          APPEAL FROM THE UNITED STATES DISTRICT COURT

                 FOR THE DISTRICT OF MASSACHUSETTS

                               Before

                    Thompson, Selya, and Lipez,
                          Circuit Judges.



     Michael D. Grabhorn, with whom Jonathan M. Feigenbaum and
Grabhorn Law Office, PLLC were on brief, for appellant.
     Joshua Bachrach, with whom Wilson, Elser, Moskowitz, Edelman
& Dicker LLP was on brief, for appellee.



                          August 16, 2013
            LIPEZ,    Circuit   Judge.      This   case   requires   us    to

determine, inter alia, whether the "safe harbor" exception to the

Employee Retirement Income Security Act of 1974 ("ERISA") applies

to the long term disability insurance policy that covers appellant

Diahann Gross.       The district court found that it did not.            The

court therefore held that Gross's state law claims were preempted.

Furthermore, it concluded that her insurer was entitled to the

highly deferential "arbitrary and capricious" review prescribed for

certain ERISA benefits decisions.         Using that standard, the court

upheld the insurer's denial of benefits to Gross.

            On appeal, Gross asserts that the district court triply

erred.   She first argues that the safe harbor exception applies,

removing her benefits claim from the ERISA scheme.            She further

maintains that, even accepting that ERISA governs, the court

reviewed the insurer's decision under the wrong standard and --

even under that standard -- reached the wrong result.

            Each of appellant's contentions raises a substantial

question.   Although we agree with the district court that the safe

harbor exception is inapplicable, we hold that the benefits denial

was subject to de novo review.      Joining several other circuits, we

conclude that language requiring proof of disability "satisfactory

to us" is inadequate to confer the discretionary authority that

would trigger deferential review.           We also conclude that the

administrative record is inadequate to allow a full and fair


                                    -2-
assessment of Gross's entitlement to disability benefits.                   Hence,

we vacate the judgment and remand the case to the district court so

that it may return the matter to Sun Life for further development

of the record as described below.

                                       I.

            In reciting the facts germane to resolution of this ERISA

appeal,   we     draw   on   the   record    that    was   before     the   claims

administrator.      Buffonge v. Prudential Ins. Co. of Am., 

, 22 (1st Cir. 2005).

A. Background

            Appellant Gross, an optician and office manager for

Pinnacle Eye Care LLC in Lexington, Kentucky, was placed on

disability leave in early August 2006, when she was 34 years old.

She complained of severe pain, weakness and numbness in her legs

and arms, and recurring headaches that had been worsening since

early 2004.       Gross's treating physician concluded that she had

reflex sympathetic dystrophy ("RSD"),1 fibromyalgia, migraines, and

chronic fatigue.        In a report signed in September 2006, the doctor

wrote that Gross "cannot work."

            Gross is covered under a long term disability ("LTD")

policy    that    Pinnacle    obtained      from    Medical   Group    Insurance

Services, Inc. ("MGIS"), a company that sells employee benefit


     1
       RSD is apparently considered equivalent to complex regional
pain syndrome, or "CRPS," and we thus refer to the two conditions
interchangeably.

                                      -3-
coverage provided by the United Health Services Employer's Trust

("the Trust").       Pinnacle had obtained group policies from the

Trust, through MGIS, since 2003,2 with the policies originally

written   by   The   Hartford   Life    &    Accident    Insurance   Company

("Hartford") and, beginning in 2006, by appellee Sun Life Assurance

Company of Canada.      Pinnacle paid 100 percent of its employees'

premiums for life and accidental dismemberment and death ("AD&D")

insurance, but the employees themselves paid for LTD coverage.

Despite the payment differences, the policies were administered

under the same group number, MGIS Group. No. 20178808, and all of

the coverage was billed to Pinnacle in a single monthly statement.3

            Shortly after leaving her job, Gross filed a claim with

MGIS seeking long term disability benefits.              The administrative

record includes voluminous medical evidence, some submitted by

Gross to support her application for benefits and some solicited by

Sun Life to aid in its evaluation.                  Sun Life also hired an

investigator to perform a background check and video surveillance

on Gross.      In April 2007, Sun Life notified Gross that it had

denied her request for benefits because of "insufficient objective

evidence to substantiate" a disability that precluded her from

coverage.

                                   -4-
performing her duties at Pinnacle.     In so concluding, the insurer

relied, inter alia, on its video surveillance and the opinions of

consulting physicians who reviewed Gross's medical history but did

not physically examine her.   Gross filed an administrative appeal,

which Sun Life rejected in January 2008 with the explanation that

it had found "no basis on which to conclude that Ms. Gross would be

unable to perform the Material and Substantial Duties of her Own

Occupation."    Sun Life emphasized the discrepancy between Gross's

activities while under surveillance and her appearance and behavior

during medical visits.

B. Procedural History

             Gross initially filed a lawsuit against Sun Life in

Kentucky state court challenging the insurer's denial of benefits

on state law grounds, but later dismissed that action without

prejudice.     In September 2009, she filed suit in Norfolk County

Superior Court in Massachusetts, again alleging only state law

causes of action.4     Sun Life removed the new action to federal

district court and filed a motion to dismiss based on ERISA

preemption.     After the court ruled in Sun Life's favor, Gross

amended her complaint to add claims under 29 U.S.C. § 1132, which,

among other things, provides a cause of action for an ERISA plan


     4
       Gross evidently chose to file her original lawsuit in
Kentucky because she lives there. After Sun Life removed that
action to federal court, Gross dismissed it and filed a new
complaint in the Massachusetts county where Sun Life maintains its
principal United States place of business.

                                 -5-
participant "to recover benefits due to him under the terms of his

plan, to enforce his rights under the terms of the plan, or to

clarify his rights to future benefits under the terms of the plan."

29 U.S.C. § 1132(a)(1)(B).

           In February 2011, Gross filed a motion asking that the

district court apply de novo review in its evaluation of her ERISA

claims, based on the Supreme Court's decision in Firestone Tire &

Rubber Co. v. Bruch, 

(1989).             See 

that the default standard for ERISA claims is de novo).               The court

denied the motion, and cross motions for summary judgment followed.

On January 6, 2012, the district court granted summary judgment for

Sun Life and denied Gross's parallel motion.                The court held that

Sun   Life's    decision    to     deny    benefits   was   not   arbitrary   and

capricious, and thus complied with ERISA's requirements.                  In so

ruling,   the    court     noted    that    plan   administrators    "'are    not

obligated to accord special deference to the opinions of treating

physicians,'" Gross v. Sun Life Assurance Co. of Canada, No. 09-

11678-RWZ, 

, at *4 (D. Mass. Jan. 6, 2012) (quoting

Black & Decker Disability Plan v. Nord, 

, 825 (2003)),

and that "even 'sporadic surveillance capturing limited activity'

may be used to uphold termination of benefits, particularly where

videos show plaintiff engaging in activities that specifically

contradict her claims as to 'how she spent her time and what

[actions] she could tolerate,'" 

Maher v. Mass.


                                          -6-
Gen. Hosp. Long Term Disability Plan, 

, 295 (1st Cir.

2011)).

            On   appeal,   Gross   asserts    that   the   district   court

incorrectly found that: (1) her long term disability policy was

part of an ERISA plan; (2) the plan gave Sun Life discretionary

authority to make claims decisions, thus allowing only arbitrary

and capricious review of the insurer's rejection of benefits; and

(3) Sun Life permissibly exercised its discretion in denying

benefits to her.    We begin as we must with Gross's contention that

her claims do not fall under ERISA.

                                    II.

            A finding that ERISA governs a benefits plan typically

will impact a plaintiff's appeal of her insurer's denial of

benefits in ways that will make that challenge more difficult. See

Johnson v. Watts Regulator Co., 

, 1131-32 (1st Cir.

1995).    The application of ERISA triggers preemption of state-law

principles, see 29 U.S.C. § 1144(a), which "may cause potential

state-law remedies to vanish, or may change the standard of review,

or may affect the admissibility of evidence, or may determine

whether a jury trial is available."          Watts 

(citations omitted); see also Aetna Health Inc. v. Davila,

, 215 (2004) ("The limited remedies available under

ERISA are an inherent part of the 'careful balancing' between

ensuring fair and prompt enforcement of rights under a plan and the


                                    -7-
encouragement of the creation of such plans." (quoting Pilot Life

Ins. Co. v. Dedeaux, 

, 55 (1987)).          Gross's vigorous

opposition     to   applying   ERISA    to   her   claim   is   therefore

unsurprising.

             With exceptions not pertinent here, ERISA applies to "any

employee benefit plan if it is established or maintained . . . by

any employer engaged in commerce or in any industry or activity

affecting commerce."     29 U.S.C. § 1003(a)(1).5      We have observed

that "the existence of a plan turns on the nature and extent of an

employer's benefit obligations," Belanger v. Wyman-Gordon Co., 

, 454 (1st Cir. 1995), and, accordingly, the two common

ways to show that a benefits decision falls outside ERISA both

involve inquiry into the employer's relationship with the benefits

under scrutiny.      First, the regulatory "safe harbor" provision

excludes "group or group-type insurance programs" from ERISA's

oversight if they satisfy four criteria:

             (1) the employer makes no contributions on
             behalf of its employees;

             (2) participation in the program is voluntary;

             (3) the employer's sole functions are to
             collect premiums and remit them to the
             insurer, and, without endorsing the program,
             to allow the insurer to publicize the program
             to its employees; and


     5
       ERISA also applies to plans established or maintained by
employee organizations or "organizations representing employees
engaged in commerce or in any industry or activity affecting
commerce." 29 U.S.C. § 1003(a)(2).

                                  -8-
               (4) the employer receives no consideration for
               its    efforts,    other    than    reasonable
               compensation   for   administrative   services
               necessary to collect premiums.

See 29 C.F.R. § 2510.3-1(j); see also Watts 

.

               A benefits program that fails the safe harbor test will

not necessarily be deemed an ERISA plan, however. Watts 

.          Exemption also may result from application of

"the conventional tests" for determining whether ERISA governs.

  benefit     plan        has   "five   essential

constituents":

               (1) a plan, fund or program (2) established or
               maintained (3) by an employer or by an
               employee organization, or by both (4) for the
               purpose of providing medical, surgical,
               hospital care, sickness, accident, disability,
               death, unemployment or vacation benefits,
               apprenticeship or other training programs, day
               care centers, scholarship funds, prepaid legal
               services   or   severance   benefits  (5)   to
               participants or their beneficiaries.


Wickman v. Nw. Nat'l Ins. Co., 

, 1082 (1st Cir. 1990)

(quoting Donovan v. Dillingham, 

, 1370 (11th Cir.

1982) (en banc)).         We have observed that "[t]he crucial factor in

determining if a 'plan' has been established is whether the

purchase of the insurance policy constituted an expressed intention

by the employer to provide benefits on a regular and long term

basis."        

   inquiry     is    performed    from   the

perspective of a reasonable person: "[A] 'plan, fund or program'

                                          -9-
under ERISA is established if from the surrounding circumstances a

reasonable person can ascertain the intended benefits, a class of

beneficiaries,       the    source    of   financing,   and   procedures   for

receiving benefits."         

).

             Thus, even if the Sun Life policy does not fall within

the regulatory safe harbor, we must separately determine if it was

a "plan" or "program" that was "established or maintained" by

Pinnacle.     Although we often start with the safe harbor inquiry,

we begin here by examining whether Pinnacle's benefits arrangement

is properly classified as an ERISA plan because that sequence

better fits our analysis.

A. Standard of Review

             Although the district court's refusal to remand this case

to   state   court    was    a   ruling    on   subject-matter   jurisdiction

engendering de novo review, see Samaan v. St. Joseph Hosp., 

, 27 (1st Cir. 2012); BIW Deceived v. Local S6, Indus. Union

of Marine & Shipbuilding Workers of Am., 

, 830 (1st

Cir. 1997), the underlying jurisdictional issue -- whether ERISA

governs the Pinnacle plan -- is a mixed question of fact and law

triggering scrutiny "along a degree-of-deference continuum," Watts

.            Where, as here, factual questions

about the plan dominate the inquiry, the clear-error standard will

be our primary tool.        See 

mind, however, that "the


                                       -10-
removing   party   bears   the   burden      of    persuasion   vis-à-vis   the

existence of federal jurisdiction." BIW 

.

B. Existence of an ERISA Plan

           The record demonstrates beyond debate that the "crucial

factor" we identified in Wickman is satisfied here, i.e., that

Pinnacle undertook to provide benefits for its employees "on a

regular and long term 

; see also, e.g.,

Anderson v. UNUM Provident Corp., 

, 1263 (11th Cir.

2004) ("[T]he 'established or maintained' requirement is designed

to ensure that the plan is part of an employment relationship

. . . ." (alteration in original) (internal quotation marks

omitted)). Pinnacle has participated in the United Health Services

Employer's Trust since at least October 2003, when the company and

MGIS representatives signed a one-page "Group Benefit Summary"

issued by the Trust that described the life, accidental death, and

LTD   coverages    available     to    Pinnacle's      employees   and   their

beneficiaries.6    So far as the record shows, each of those benefits

has been offered to employees or provided at no cost on an ongoing

basis since that time.

           Gross    does   not    address         ERISA's   applicability    to

Pinnacle's insurance benefits generally, but focuses instead on the



      6
       The Trust also provided short-term disability coverage for
Pinnacle.   The "Remarks" section of the Group Benefit Summary
directs the reader to "[s]ee [the] attached addendum for Short Term
Disability benefits." The addendum is not in the record.

                                      -11-
LTD policy.   Emphasizing that the LTD policy is the only one the

employees must pay for themselves,7 she seeks to divorce that

policy from any benefit "program" and have us separately evaluate

whether ERISA applies to it.   The district court, however, viewed

the LTD policy as one part of a "comprehensive employee benefit

plan."   Gross v. Sun Life Assurance Co. of Can., No. 09-11678-RWZ,

, at *2 (D. Mass. March 4, 2010).   We detect no clear

error in that conclusion.   As detailed below, the record provides

ample support for the court's finding that Pinnacle's package of

insurance benefits constituted a unitary ERISA program.8

           Significantly, the Trust identifies all of the Pinnacle

employee policies by a single group number.   In addition, as noted

above, the Group Benefit Summary issued by the Trust referred to

all of those policies.   Paul Wedge, the "owner-member" of Pinnacle

who signed the Summary on behalf of the employer, is noted on the



     7
       As noted earlier, the record does not reveal whether
Pinnacle funded its employees' short-term disability coverage,
although the district court stated that, while Gross paid her own
LTD premium, Pinnacle funded "all the others." Gross v. Sun Life
Assurance Co. of Can., No. 09-11678-RWZ, 

, at *1 (D.
Mass. March 4, 2010).
     8
       Gross points to a statement by Paul Wedge of Pinnacle that
the company did not intend to create an ERISA welfare benefits
plan. The question, however, is not the employer's intent vis-à-
vis ERISA, but whether the employer "intended to establish or
maintain a plan to provide benefits to its employees as part of the
employment relationship." 

; see also,
e.g., Watts 

n.5 (discussing the Safe
Harbor elements and noting that "this case turns on the employer's
activities, not its intentions").

                                -12-
document as the administrative contact, without distinction among

policies.      Similarly, invoices sent to Pinnacle by MGIS in 2006

list the life, AD&D, LTD, and short-term disability policies with

the amounts due for each.        The record also contains an "Employer's

Participation Agreement," signed by Wedge in 2006, requesting

membership in the Trust "and coverage under the Group Policies

issued to the Trustees of the Trust now in effect or later modified

or replaced," again without distinction among the different types

of insurance offered by the Trust.

              The Trust polices have thus consistently been treated as

a     unit,   despite   their    different      contribution     requirements.

Moreover, the information provided to employees was in keeping with

that approach.     The record contains single-page summary fliers for

the    life    insurance   and     LTD    coverages    that   are   similar    in

appearance, both containing the Sun Life logo in the upper right

corner and both offering "Highlights" of the particular policy "for

Employees of Pinnacle Eye Care, LLC."                  The disability flier

contains instructions on how to enroll, directs employees to return

the form to their employer, and tells them that they "must elect or

refuse    insurance     coverage    within      31   days   of   your   date   of

eligibility" -- creating an explicit link between that form of

insurance and Pinnacle notwithstanding the employer's lack of

financial involvement.      The link is reinforced by the requirement

that an enrolling employee acknowledge the following understanding:


                                         -13-
"I am requesting LTD coverage under a Group Insurance policy

offered by my employer.   This coverage will end when my employment

terminates."   Yet another indicator of Pinnacle's role is the fine

print at the bottom of the flier describing the LTD coverage as a

"benefit[] available from your employer" and advising employees

that Pinnacle will provide a copy of Sun Life's LTD booklet with

complete details "[w]hen you become eligible for benefits under the

plan."

          In these circumstances, we see no justification for

isolating the long-term disability policy from Pinnacle's insurance

package for purposes of our ERISA inquiry.    A "plan" under ERISA

may embrace one or more policies, see 

(noting that a benefits plan or program may consist of "a group

policy or multiple policies"), quoted in 

,

and it strikes us as both impractical and illogical to segment

insurance benefits that are treated as a single group and managed

together, potentially placing some under ERISA and some outside the

statute's scope.   In so concluding, we join several other courts

that have declined to "unbundle[]" a set of policies or benefits

offered by an employer to its employees when evaluating whether

ERISA governs.   Postma v. Paul Revere Life Ins. Co., 

,

538 (7th Cir. 2000); see also Gaylor v. John Hancock Mut. Life Ins.

Co., 

, 463 (10th Cir. 1997) (rejecting plaintiff's

attempt to "sever her optional disability coverage from the rest of


                                -14-
the benefits she received through her employer's plan");9 Peterson

v. Am. Life & Health Ins. Co., 

, 407 (9th Cir. 1995)

(concluding that policy that did not on its own comply with ERISA

requirements nonetheless fell under the statute because it "was

just one component of [the] employee benefit program and . . . the

program, taken as a whole, constitutes an ERISA plan");10 Pando v.

Prudential Ins. Co. of Am., 

, 736 (W.D. Tex.

2007) ("[W]here the employer contributes to some, but not all,

benefits which arise from the employment relationship, a court will

separately evaluate whether a particular policy is an ERISA plan



     9
       Gross asserts that Postma and Gaylor are distinguishable
because the companies in each instance paid the premiums for all of
the policies. She is correct that, in Postma, the employer took
over paying the LTD premium from the employees. 

. The circumstances in Gaylor are less clear. The opinion
states in one place that the employer contributed part of the LTD
premium "for certain 

, but elsewhere
indicates that the plaintiff paid the full cost of her coverage,
see 

of these distinctions, the pertinent
point is that "the disability policy was part of a broader benefits
package maintained by [the employer] for its employees." 

.
     10
       In Peterson, the policy at issue would not on its own have
qualified as an ERISA plan because coverage was provided only to a
partner in a business partnership and not to any employees. 

(citing 29 C.F.R. § 2510.3-3(b)). We offer no view on
the Peterson court's conclusion that a policy ineligible for ERISA
coverage may nevertheless be governed by the statute if it is part
of an ERISA-covered employee benefit program.       In a somewhat
similar context -- where the benefit at issue (reimbursement for
educational expenses) is not among those protected by ERISA -- the
Eleventh Circuit held that the benefit's inclusion in a plan
providing ERISA-covered employee benefits did not bring the non-
ERISA benefit within the statute's scope. See Kemp v. IBM Corp.,

, 713 (11th Cir. 1997).

only when it is clearly separate from the benefits plan to which

the employer does contribute."); cf. Smith v. Jefferson Pilot Life

Ins. Co., 

, 567 (11th Cir. 1994) (rejecting plaintiff's

attempt "to sever the dependent coverage feature from the benefits

package provided . . . through the Plan").11

             Having concluded that the LTD policy must be treated as

part of Pinnacle's longstanding insurance benefits program, we also

conclude that a reasonable person could readily ascertain the

program's    specific      elements   --     the   benefits,    the     class   of

beneficiaries, the source of funding, and procedures for obtaining

benefits.    See 

.          The one-page Highlights

fliers for the LTD and the combined life and AD&D insurance

policies generally describe the benefits, costs, and enrollment

procedure,    and   they    direct    employees    to   Sun    Life's   detailed

booklets for "complete plan details."              The life insurance flier

notes that eligible employees will need to designate beneficiaries

using one of two identified forms, and the LTD flier states that




     11
       As the Eleventh Circuit noted in 

n.3,
the Supreme Court, in a different context, has recognized the
importance of treating benefits plans holistically.      See Shaw v.
Delta Air Lines, Inc., 

, 107-108 (1983) ("The
administrative impracticality of permitting mutually exclusive
pockets of federal and state jurisdiction within a plan is
apparent."); see also 

n.3 (stating that,
based on Shaw, "we may infer that, generally, ERISA plans may not
be severed so that portions of them may be excluded from regulation
under ERISA").

                                      -16-
the benefits are "[a]vailable to all full time employees working 30

or more hours per week."

               Also in the record is an individualized LTD "Benefit

Highlights" form prepared for Gross that lists pertinent details of

the Sun Life policy, among them the waiting period for eligibility

("1st of the month following full-time employment"); the benefit

percentage of earnings (sixty percent); the maximum monthly benefit

($9,000); and the elimination period (180 days). Sun Life's forty-

seven page LTD booklet contains instructions on filing a claim and

explains the appeals process, including "your right to bring a

civil    action     under   ERISA,    §    502(a)     following    an   adverse

determination on review."          See 

(noting

that handbook detailing ERISA rights, distributed to employees, "is

strong evidence that the employer has adopted an ERISA regulated

plan"); cf. Thompson v. Am. Home Assurance Co., 

, 437

(6th    Cir.    1996)   (noting,   among     facts   undermining   finding   of

employer endorsement, that "[t]he policy documentation . . .

nowhere mentions that the policy is subject to ERISA" nor describes

employee's ERISA rights).

               In combination, the documents in the record associated

with Pinnacle's employee benefits program establish all five of the

constituent elements of an ERISA plan listed in Wickman: (1) a

plan, (2) established and maintained (3) by an employer (4) to

provide multiple types of insurance benefits (5) to employees and,


                                      -17-
in some cases, their beneficiaries.12   The materials further show

that a reasonable Pinnacle employee would understand the nature of

the plan, including the scope of coverage, the costs for the plan's

different components, and the claims procedures.       Inescapably,

Pinnacle's arrangement with MGIS and the Trust represented a

"calculated commitment to qualified employees for similar benefits

regularly in the future." 

. We therefore

conclude that Pinnacle offered LTD benefits to its employees under

a "plan" or "program" that is subject to ERISA.

C. The Safe Harbor Exception

            Gross's argument that the safe harbor exception applies

depends on her assumption that the LTD policy may be examined

independently from the rest of Pinnacle's insurance benefits plan.

Based on that assumption, she asserts that three of the four safe

harbor requirements are clearly met: Pinnacle does not contribute

to her LTD policy, her participation was voluntary, and Pinnacle

did not receive any consideration in connection with the sale of

the LTD policy to its employees.   See Watts 

.     She states that only the fourth requirement -- that the




     12
       An ERISA plan may be created without formal documentation.
See 

(noting that "[t]here is no
requirement of a formal, written plan in either ERISA's coverage
section . . . or its definitions section"); see also N.E. Mut. Life
Ins. Co. v. Baig, 

, 5 n.6 (1st Cir. 1999) (citing
Donovan).

                                -18-
employer's sole functions are administrative and do not reflect

endorsement of the policy -- is "reasonably in dispute."

             Our    rejection       of   Gross's       assumption    that    Pinnacle

provided multiple, independent plans is fatal to her safe harbor

argument.          The   exception       does    not    apply    unless     all   four

requirements are met, 

funding of the life

and AD&D insurance is thus sufficient to disqualify the Pinnacle

plan.   In addition, with respect to the "endorsement" criterion,

the Pinnacle plan falls short as well.                 Our discussion above shows

the close relationship between the LTD plan and the other Pinnacle

insurance benefits, which were treated alike except for who paid

the premiums.        In an affidavit, Pinnacle's Wedge stated that the

employer "did not negotiate the terms of the voluntary long term

disability insurance policy from Sun Life."                 Although the employer

did   not   specify      the    policy's    terms,      MGIS's   benefits     manager

reported that Pinnacle did provide guidelines for eligibility,

submitting    "a     list      of   eligible     employees      as   well   as    class

definitions, classes for each employee, plan waiting periods, and

plan designs."

             Thus, eligibility for this LTD policy was not only tied

to employment at Pinnacle, but Pinnacle also determined which

employees had access to that benefit.                     Consequently, both in

outward appearance and internally, Pinnacle played more than a

bystander's role concerning the LTD policy.                  See Watts Regulator,


                                          

(linking endorsement to the employer's "engagement

in activities that would lead a worker reasonably to conclude that

a    particular      group   insurance      program   is    part   of   a   benefit

arrangement backed by the company"); 

(holding that a finding of endorsement may be appropriate "where

the employer plays an active role in . . . determining which

employees will be eligible for coverage"); ERISA Op. Letter No. 94-

26A,    

,    at   *3    (July    11,    1994)   (stating    that

endorsement occurs "if the [employer] engages in activities that

would lead [an employee] reasonably to conclude that the program is

part of a benefit arrangement established or maintained by the

[employer]").

               In short, because Pinnacle's insurance benefits program

is an ERISA plan, and the safe harbor exception is inapplicable, we

must determine the proper ERISA standard of review.

                                          III.

A.    Background

               The question of what standard of review is applicable to

a benefits decision governed by ERISA is an issue of law that we

review de novo.       

.         The default standard for

reviewing benefits decisions also is de novo, and plenary review is

displaced only if the benefit plan gives discretionary authority to

the    administrator     or    fiduciary     to    determine   eligibility     for

benefits.      See 

; 

.


                                          -20-
If   the    plan   affords    such   discretion,    the    court   applies     "a

deferential 'arbitrary and capricious' or 'abuse of discretion'

standard."     

(quoting Cusson v. Liberty Life

Assurance Co. of Bos., 

, 224 (1st Cir. 2010)).13

             The   district    court   summarily    denied    Gross's   motion

seeking application of de novo review. Sun Life urges us to affirm

that ruling, arguing that the LTD policy contains sufficiently

clear language granting discretionary authority to the insurer and

that    Pinnacle    accepted    that    language,    and     the   resulting

deferential review of benefits decisions, when it signed the

Employer's Participation Agreement with the Trust.14                 Sun Life

points specifically to two statements in the policy: "Proof [of

claim] must be satisfactory to Sun Life" and "Benefits are payable

when Sun Life receives satisfactory Proof of Claim."                 Sun Life

relies on our decision in Brigham v. Sun Life of Canada, 

(1st Cir. 2003), where we accepted the view that language in a

different Sun Life policy comparable to the pertinent language here



       13
       The parties' arguments on this issue rely on the language
contained in a booklet that is described therein as "intended to
provide a summarized explanation of the current Group Policy
Benefits."    The booklet warns that "the Group Policy is the
document which forms Sun Life's contract to provide benefits."
Because the parties do not assert otherwise, we presume that the
language in the booklet and the language in the policy are the same
for our purposes.
       14
       The Agreement states, inter alia, that "upon acceptance for
participation under the policies, Participant will be bound by the
terms of this Request form and Policies."

                                       -21-
constituted "an indicator of subjective, discretionary authority on

the part of the administrator."    

Sun Life is correct that the language at issue

in Brigham is similar to the language now before us,15 two factors

important to our decision in Brigham are absent here.          First,

plaintiff Brigham advocated for de novo review for the first time

on appeal, having assumed throughout the district court proceedings

that the arbitrary and capricious standard applied.        We saw no

injustice in rejecting Brigham's belated argument based on our well

established raise or waive rule, and without "undertak[ing] a

thorough exploration of the issue," in light of the "widespread

acceptance" by courts at that time that the phrase "satisfactory to

us" triggers discretionary review.      

our decision in Brigham, however, the precedential

landscape -- the second important factor -- has changed.           In

Brigham, decided more than a decade ago, we noted the split in the

circuits on whether policy provisions containing a "satisfaction"

requirement were sufficient to confer discretionary authority

triggering deferential review.     

reported that

some circuits considered the use of "to us" after "satisfactory" to


     15
        To the extent it differs, the Brigham language is more
expansive. The Sun Life policy there stated that the insurer "'may
require proof in connection with the terms or benefits of [the]
Policy'" and further declared: "'If proof is required, we must be
provided with such evidence satisfactory to us as we may reasonably
require under the circumstances.'" 

(alteration in original) (emphasis removed).

                                 -22-
be "an indicator of subjective, discretionary authority on the part

of the administrator, distinguishing such phrasing from policies

that simply require 'satisfactory proof' of disability, without

specifying who must be satisfied."           

inter alia,

Nance v. Sun Life Assurance Co. of Can., 

, 1267-68

(10th Cir. 2002); Ferrari v. Teachers Ins. & Annuity Ass'n, 

, 806 (8th Cir. 2002)).        Only the Sixth Circuit, in an 8-6

en banc decision, had held that discretionary review is triggered

by a requirement of "'satisfactory proof' without specification of

who must be satisfied."       

Perez v. Aetna Life

Ins. Co., 

, 556-58 (6th Cir. 1998) (en banc)).                 The

Second Circuit, in dicta, stood alone in suggesting that the

"satisfactory to us" language might not convey discretion.           

Kinstler v. First Reliance Standard Life Ins. Co., 

, 252 (2d Cir. 1999)).

           Although the division of opinion remains, three circuits

have in the interim adopted the Second Circuit's suggestion that

the "to us" amplification on "satisfactory" is inadequate in itself

to confer discretion.     See Viera v. Life Ins. Co. of N.A., 

,   414-417   (3d   Cir.   2011)    (describing    cases);   Feibusch    v.

Integrated Device Tech., Inc. Emp. Benefit Plan, 

, 884

(9th Cir. 2006); Diaz v. Prudential Ins. Co. of Am., 

,

639-40 (7th Cir. 2005).       In reaching that conclusion, the Seventh

Circuit panel departed from its own prior precedent and thus


                                      -23-
submitted its proposed decision to all active judges before it was

published.      No judge requested en banc review.     See 

.      On the other hand, at least one circuit has reaffirmed its

earlier view that a plan requiring submission of "'satisfactory

proof of Total Disability to [the plan administrator]'" granted

discretion to the administrator.      See Tippitt v. Reliance Standard

Life Ins., 

, 1233-34 (11th Cir. 2006) (quoting

Levinson v. Reliance Standard Life Ins., 

, 1324-25

(11th Cir. 2001)).

              The procedural backdrop of Brigham and the intervening

circuit court decisions mean that the standard of review issue in

this case cannot be resolved, as Sun Life cursorily asserts, on the

ground that it is governed by Brigham.        That decision explicitly

relied on the plaintiff's procedural default, which we declined to

sidestep because of the then-current state of the law: "[W]ith the

possible exception of the Second Circuit in dicta, no federal

appeals court has viewed the type of language at issue in this case

as inadequate to confer discretion on the plan 

.      Here, where we do not have procedural default and we

do    have    out-of-circuit   precedent   rejecting   the   adequacy   of

"satisfactory to us," our acceptance of the language in Brigham is

not binding. Rather, the time is now appropriate for the "thorough

exploration of the issue" that we put off in 

.


                                   -24-
B.   The Pursuit of Clarity

            We have long recognized that the threshold question in

determining the standard of review is whether the provisions of the

benefit plan at issue "reflect a clear grant of discretionary

authority   to   determine   eligibility   for   benefits."   Leahy   v.

Raytheon Co., 

, 15 (1st Cir. 2002) (emphasis added). In

Leahy, for example, we observed that the "discretionary grant

hardly could be clearer" where the plan documents gave the insurer

"'the exclusive right, in [its] sole discretion, to interpret the

Plan and decide all matters arising thereunder,'" and further

provided that the insurer's decision "in the exercise of that

authority 'shall be conclusive and binding on all persons unless it

can be shown that the . . . determination was arbitrary and

capricious.'" 

in original); see also,

e.g., Twomey v. Delta Airlines Pilots Pension Plan, 

, 31

(1st Cir. 2003) (giving administrative committee "'such duties and

powers as may be necessary to discharge its responsibilities under

the Plan, including . . . decid[ing] all questions of eligibility

of any Employee . . . to receive benefits,'" with such decisions,

assuming good faith, "'to be final and conclusive'" (first omission

and alteration in original)).

            The wording at issue here is obviously a far cry from the

explicit provisions in Leahy and Twomey.         There are no required

"magic words," however, to confer discretion, and "language that


                                  -25-
falls short of th[e] ideal" can suffice.   

.

Here, the two pertinent sentences appear in a section of the LTD

insurance booklet in which a series of questions about claims

procedures are asked and answered.      The first three questions

address how a claim is submitted.   The next question asks "What is

considered Proof of Claim?"    The response includes one of the

sentences under scrutiny:

          Proof of Claim must consist of at least the
          following information:
          -a description of the disability;
          -the date the disability occurred; and
          -the cause of the disability.

          Proof of claim may include, but is not limited
          to, police accident reports, autopsy reports,
          laboratory   results,    toxicology   results,
          hospital records, x-rays, narrative reports,
          or other diagnostic testing materials as
          required.

          Proof of Claim for disability must include
          evidence    demonstrating    the  disability
          including, but not limited to, hospital
          records,   Physician   records,  Psychiatric
          records, x-rays, narrative reports, or other
          diagnostic testing materials as appropriate
          for the disabling condition.

          Sun Life may require as part of the Proof,
          authorizations to obtain medical and non-
          medial information.

          Proof of your continued disability and regular
          and continuous care by a Physician must be
          given to Sun Life within 30 days of the
          request for proof.

          Proof must be satisfactory to Sun Life.




                               -26-
App. at 250 (emphasis added).             The next question in sequence asks

when benefits will be received, with this response: "Benefits are

payable when Sun Life receives satisfactory Proof of Claim."                          

   note   initially      that    the        second     reference     to

satisfactory proof lacks the "to us" modifying phrase and is thus

used in a way that, as we noted in Brigham, most courts consider

inadequate to signify discretionary authority. 

;

see also 

.             We agree, and we therefore focus

on the "satisfactory to us" (here, "satisfactory to Sun Life")

formulation.

              The    courts     deeming       even     the      "to     us"    wording

insufficiently explicit have offered several justifications for

their conclusions. The Second Circuit observed that specifying the

need to satisfy the administrator adds nothing to the obvious point

that "[n]o plan provides benefits when the administrator thinks

that benefits should not be paid."               

.

That    assessment      was    echoed   in    Diaz:     "All    plans     require     an

administrator first to determine whether a participant is entitled

to benefits before paying them; the alternative would be to hand

money   out    every    time    someone      knocked    on    the     door,   which   is

obviously out of the 

.           According to

these    courts,       there    must    be    language        that     "unambiguously

indicate[s] that the plan administrator has authority, power, or


                                        -27-
discretion to determine eligibility or to construe the terms of the

Plan."     

(internal quotation marks

omitted); see also 

(stating that in order

for a plan to be insulated from de novo review, it must reveal that

the administrator "'has the power to interpret the rules, to

implement the rules, and even to change them entirely'" (quoting

)); 

-40 ("[T]he critical

question is whether the plan gives the employee adequate notice

that the plan administrator is to make a judgment within the

confines of pre-set standards, or if it has the latitude to shape

the application, interpretation, and content of the rules in each

case.").

           Both the Ninth and Seventh Circuits emphasized that the

"satisfactory to us" construct fails to alert plan participants to

the administrator's discretion because it is ambiguous as to what

must be satisfactory to Sun Life.     When faced with language and

context virtually identical to that before us -- also in a Sun Life

policy -- the Ninth Circuit easily dismissed the wording as

inadequate:

           [T]he Sun Life policy language simply does not
           clearly indicate that Sun Life has discretion
           to grant or deny benefits.        Indeed, the
           language makes no reference whatsoever to
           granting or denying benefits, and is included
           under the policy heading "What is considered
           proof of claim?"    We construe ERISA policy
           ambiguities in favor of the insured.




                               -28-


.        The Seventh Circuit likewise found the

"satisfactory to us" phrase ambiguous, observing that,

             [f]airly read, it suggests only that the plan
             participant must submit reliable proof of two
             things: continuing disability and treatment by
             a doctor. In short, under [the policy], the
             only discretion reserved is the inevitable
             prerogative to determine what forms of proof
             must be submitted with a claim -- something
             that an administrator in even the most tightly
             restricted plan would have to do.

; see also 

(observing

that "the only discretion reserved by this single phrase, nested

within a section wholly regarding the procedural requirements for

submission of a claim, is 'the inevitable prerogative to determine

what forms of proof must be submitted with a claim'" (quoting Diaz,

supra)).16

             All four courts rejecting the adequacy of "satisfactory

to us" recommended the use of language that either explicitly

"stat[es] that the award of benefits is within the discretion of

the   plan   administrator   or    .    .     .   is   plainly   the   functional

equivalent of such wording," and three of the courts proposed



      16
       The policy at issue in Viera covered accidental death and
dismemberment.    The pertinent language appeared in a section
labeled "Proof of Loss" and stated: "'Written or authorized
electronic proof of loss satisfactory to Us must be given to Us at
Our office, within 90 days of the loss for which claim is 

. The court explained the ambiguity in the language
as follows: "In other words, it is not clear whether 'satisfactory
to Us' means 'electronic proof of loss [in a form] satisfactory to
Us' or 'electronic proof of loss [substantively and subjectively]
satisfactory to Us.'" 

specific language.    

; see also 

("'Benefits under this plan will be paid only if the

plan administrator decides in [its] discretion that the applicant

is entitled to them.'" (quoting Herzberger v. Standard Ins. Co.,

, 331 (7th Cir. 2000)); 

("The

plan administrator has discretionary authority to grant or deny

benefits under this plan." (internal quotation marks omitted));

(stating that "the surest way" for a plan to

insulate its benefits denial from de novo review is to "includ[e]

language that either mimics or is functionally equivalent" to the

Herzberger language).

C. Our Conclusion

           Our   acknowledgment     in      Brigham       of     "an     increasing

recognition of the need for the clearest signals of administrative

discretion" foreshadowed the insistence on "greater precision" that

has surfaced in the later 

.              Although we

refrained there from entering the discussion in light of the

appellant's   procedural   default,       we   did    "wholly      endorse"       the

Herzberger model language that the Third and Seventh Circuits have

since   expressly   recommended.      

   now    fully

considered the issue, we agree with those courts holding that the

"satisfactory to us" wording, without more, will ordinarily fail to

meet the "requisite if minimum clarity" necessary to shift from de

novo to deferential review.    

.                    We are


                                   -30-
persuaded      primarily   by    the    ambiguity    of   the    phrase,   which

reasonably may be understood to state Sun Life's right to insist on

certain   forms    of    proof   rather    than     conferring   discretionary

authority over benefits claims.           Indeed, in the present context,

the language more naturally supports the former reading, as the

phrase appears following a listing of the required information and

appropriate types of evidence to prove a claim.17 We reiterate that

no precise words are required.                Yet, to secure discretionary

review, a plan administrator must offer more than subtle inferences

drawn from such unrevealing language.             To conclude otherwise would

negate our requirement of a clear grant of discretion.                        See

("We have 'steadfastly applied Firestone to

mandate   de    novo    review   of    benefits    determinations    unless   "a

benefits plan . . . clearly grant[s] discretionary authority to the

administrator."'" (alterations in original) (quoting Terry v. Bayer

Corp., 

, 37 (1st Cir. 1998)); 

("'Neither the parties nor the courts should have to divine whether

discretion is conferred.         It either is, in so many words, or it

isn't." (quoting Sandy v. Reliance Standard Life Ins. Co., 

, 1207 (9th Cir. 2000)).




     17
        Although the language as used here is unquestionably
ambiguous, we do not foreclose the possibility that the same phrase
may be clear if used in a context where the only plausible meaning
would link it to the administrator's discretion to make eligibility
determinations.

                                       -31-
           Two additional factors contribute to our decision.

First, it is not difficult to craft clear language. The model text

offered by other courts -- including the wording endorsed in

Brigham -- demonstrates that "clear language can be readily drafted

and included in policies."   

; see also

-84 ("[I]t is easy enough to confer

discretion unambiguously if plan sponsors, administrators, or

fiduciaries want benefits decisions to be reviewed for abuse of

discretion." (internal quotation marks omitted) (alteration in

original)).   Second, the drafters of ERISA plans have had ample

time to take heed of the developing precedent rejecting the

adequacy of the "satisfactory to us" language.

           Indeed, Sun Life had every opportunity to avoid an

adverse ruling on this issue.      Our decision in Brigham, which

indicated discomfort with the clarity of the "satisfactory to us"

wording, made reliance on that language a risky strategy for

securing discretionary review of benefits decisions.     Sun Life's

relationship with the Trust began in 2006 -- three years after

Brigham and a year after Diaz.     Sun Life was also the insurer in

Brigham.   We see no reason why it could not have inserted more

explicit language in either its policy or the summary policy

booklet that it provided to Gross and the other employees covered

by the Trust's group policies.




                                 -32-
           In sum, the "satisfactory to us" language as used in the

Sun Life policy insuring Gross does not state with sufficient

clarity "that the plan administrator is to make a judgment largely

insulated from judicial review by reason of being discretionary."

.        Hence, Sun Life's rejection of

Gross's claim for benefits is subject to de novo review.

                                  IV.

A. Standards of Review

           As with any summary judgment appeal, we review a district

court's decision on the merits of an ERISA benefits case de novo.

See Kansky v. Coca-Cola Bottling Co. of New Eng., 

, 57

(1st Cir. 2007).     Given that we play the same role as the district

court in evaluating Sun Life's denial of benefits, we have chosen

not to remand to that court for application of the correct, de

novo, standard for reviewing Sun Life's decision.

           Both in the district court and on appeal, however, the

summary judgment analysis in ERISA benefits cases differs from the

ordinary   summary   judgment   inquiry   "in   one   important   aspect."

Orndorf v. Paul Revere Life Ins. Co., 

, 517 (1st Cir.

2005).     In these cases, "where review is based only on the

administrative record before the plan administrator and is an

ultimate conclusion as to disability to be drawn from the facts,

summary judgment is simply a vehicle for deciding the issue." 

in an ERISA benefits case is thus not entitled


                                  -33-
to the usual inferences in its favor.                Id.; see also 

.

           Where, as here, a challenged denial of benefits is

subject to de novo review under ERISA because there has been no

grant of discretionary authority, "our task on appeal 'is to

independently weigh the facts and opinions in the administrative

record to determine whether the claimant has met [her] burden of

showing that [she] is disabled within the meaning of the policy.'"

Scibelli v. Prudential Ins. Co. of Am., 

, 40 (1st Cir.

2012) (quoting Richards v. Hewlett-Packard Corp., 

, 239

(1st Cir. 2010)).        In so doing, we give no deference to the

administrator's opinions or conclusions.               

   summarizing      both    the   evidence   in   the

administrative record and Sun Life's decisions rejecting Gross's

claim for benefits.

B. Gross's Medical Evidence

           1.   Dr. Rita Egan

           The physician who recommended that Gross stop working,

Dr. Rita Egan, a rheumatologist, began treating Gross in February

2006.   The doctor ordered a triple-phase bone scan to look for

evidence   of   RSD,    but   the     results   were    negative.     Dr.     Egan

nonetheless concluded that Gross probably had the disease in her

right arm, as well as other conditions that were contributing to

her   difficulties.      For    the    first    of    three   insurance-related


                                       -34-
assessments    that   Dr.   Egan   subsequently   completed,   the   doctor

prepared an Attending Physician's Statement dated September 23,

2006, classifying Gross's impairment level from her combination of

medical problems as a "[s]evere limitation of functional capacity;

incapable of minimum (sedentary[]) activity."         On the line asking

for "objective findings," Dr. Egan wrote that Gross experienced

"[p]ain to touch all over but [right] arm is untouchable."              The

doctor did not note any mental impairment, although she had

prescribed an anti-depressant to Gross in April 2006 and stated at

that time that, if the drug did not work, Gross would "need[] to

see a psychiatrist to help us with her medication."18

            In the second such statement, completed in October 2006,

Dr. Egan stated that Gross's pain had worsened over time, despite

treatment, and that Gross could not sit in one place or drive for

more than ninety minutes, use her right hand, or firmly grasp with



     18
          In notes dated September 20, 2006, Dr. Egan reported:

     1. Chronic migraines -- a little improved with present
     regimen of medications.
     2.   Widespread pain and right arm reflex sympathetic
     dystrophy -- she is doing a little better with the
     medications we have her on, but I think a lot of the
     problem is depression. It certainly is contributing to
     her pain. She also is not sleeping well. At this point,
     I am going to look into another neurosurgeon or
     anesthesiologist who may be able to put an implantable
     stimulator or consider cranial stimulation therapy, which
     I have been reading about with fibromyalgia, and also the
     patient needs to see a psychiatrist to help with a lot of
     issues.


                                    -35-
her left hand.      She reiterated her findings that Gross suffered

from RSD, fibromyalgia, widespread pain, and fatigue.          Two months

later, in the third report ("Attending Physician's Supplemental

Statement"), Dr. Egan confirmed Gross's limitations,19 adding that

she could not lift more than ten pounds.          The doctor described

Gross's diseases as "chronic" and stated that her condition was

expected to last for her lifetime.

             2. Other Medical Evaluations

             In addition to her ongoing treatment with Dr. Egan, Gross

consulted with several other medical practitioners.            In October

2005, before she began seeing Dr. Egan, Gross was evaluated by Dr.

Tarvez    Tucker   for   complaints   of   headaches,   neck   pain,   and

scoliosis.      Diagnostic tests showed no abnormalities, but Dr.

Tucker noted her pain and weakness symptoms:

             [Gross] has intractable transformed migraine,
             chronic daily headache, which has not been
             responsive       to      a    variety       of
             preventatives. . . . She also has . . . a lot
             of radicular upper extremity and cervical pain
             associated with tingling and numbness of the
             right arm and hand, which is worse at the end
             of the day. She has on examination a drift of
             the outstretched right upper extremity without
             pronation, weakness of the intrinsic hand
             muscles, and diminished perception of primary
             sensory modalities in the right arm and face.




     19
       This report varied slightly from the previous one, stating
that Gross could not stand or walk for more than an hour, drive for
more than ninety minutes, or sit in one place for more than two
hours.

                                  -36-
In December, Dr. Tucker noted that her headaches had improved, but

Gross reported worsening joint and muscle pain.

            Dr.    Egan    twice   referred    Gross    to pain management

specialists.      In April and May 2006, she saw Dr. William Witt, who

diagnosed    her    with   fibromyaligia,     CRPS,    and   "probable   post

traumatic stress disorder" related to a history of sexual abuse.20

In May, Dr. Witt observed that "[h]er right hand continues to be

reddened, somewhat swollen, and she is holding in a claw position."

He deferred medical intervention until after a scheduled evaluation

and treatment by a psychologist,21 but there is no indication in the

record that such an evaluation took place.22           The following year,



     20
          Among his written findings were the following:

     She has multiple health-related problems, various aches
     and pains throughout her body. . . .

     . . . She has definite swelling of the right hand as
     compared with the left. There is obviously differential
     sweating as well.     . . . [Her gait] is slow and
     purposeful . . . . She has multiple tender points in all
     of the classic sites for fibromyalgia.
     21
       Dr. Witt noted that he was "very hesitant to engage in any
interventional treatment or any further medical treatment . . .
until we have had a chance to work with her from a behavioral
standpoint which may serve several purposes . . . as this is
clearly a sympathetically maintained pain."
     22
        As reported in another doctor's notes, Gross apparently
explained to Dr. Egan that she could not afford to see the
psychiatrist to whom she originally was referred and was to
investigate other options. Dr. Egan stated in August 2006 that her
scheduled appointments with a psychologist "did not work out . . .
because they cancelled." Gross was, however, treated with anti-
depressants.

                                    -37-
in March 2007, Gross saw Dr. Fred Coates, who joined the chorus of

doctors who diagnosed her with fibromyalgia and either RSD or CRPS.

Dr. Coates observed that she was "showing signs of severe pain

while seated," and further noted that her right arm hung "limply at

her side."    He described her right hand as "red, slightly swollen,

cool to the touch and sweating."     He also recommended psychiatric

or psychological counseling and treatment.

             Meanwhile, in January 2007, Gross underwent a functional

capacity evaluation ("FCE") to determine her physical capabilities.

The physical therapist who performed the evaluation offered a

"[p]rimary" diagnosis of CRPS or RSD, and a "[s]econdary" diagnosis

of fibromyalgia.     He reported swelling of her right hand, as well

as a "shiny" appearance, perspiration, and "increased temperature

to touch vs. the left."      The report identifies a number of "key

limitations" in Gross's physical abilities, including lack of

functional use of her right arm, poor standing balance, inability

to perform sustained overhead activity, need for assistance or a

handrail to negotiate stairs, and inability to crouch, kneel, squat

or crawl.    The document also lists numerous medications that Gross

reported using on a daily basis: Wellbutrin, Duragesic patches,

Klonipin, Tizanadine, Lortab, Ambien CR, Valtrex, Estrostep FE,

Senokot, Tylenol Rapid Release, Excedrin Tension Headache, and

Phaxyme.     The FCE concludes that Gross

             does not present at a functional level that
             could maintain sustained work activity. Her

                                 -38-
           overall level of physical activity is well
           below the sedentary level category based upon
           the frequent position change requirement, lack
           of bilateral activity ability, and short
           length of time able to perform activity.
           Unless there is a significant change in her
           current level of activity, it is not known
           what form of employment this client would be
           able to obtain.

C.   Surveillance Evidence

           Sun Life supplemented the medical evidence by arranging

for nine days of video surveillance of Gross during November 2006

and in January and February 2007.       The investigator's written

reports reveal little activity by Gross during most of the

surveillance days, with three exceptions.    First, on November 9,

2006, shortly after dropping off a teenager believed to be her

stepdaughter at school, Gross was observed driving for about an

hour and a half to her mother's home, with a brief stop at a rest

area along the way.    Second, during the evening of January 11,

2007, Gross drove a short distance with her stepdaughter to a

Kmart, where she was observed bending down toward lower-level

shelves, extending her arms above her head to retrieve items, and

kneeling to examine other items.      Third, on February 21, after

receiving a phone call that her mother had been admitted to the

hospital with chest pain, Gross drove to a gas station, pumped gas

using her right hand, and then drove for two hours to the hospital,




                               -39-
with a brief stop halfway through the trip. About two hours later,

she left the hospital and drove home.23

            The   surveillance    reports    showed   inconsistencies      in

Gross's stamina and physical abilities. On multiple occasions, she

was seen limping, but also was twice described as "jogging" a few

steps.     On November 7, for example, Gross left home with her

husband at 7:17 AM to vote at a local elementary school, returned

home at 7:34 AM, and then departed again with her stepdaughter at

8:21 AM for an apparent appointment at a nearby office building.

When they returned home at 9:27 AM, Gross appeared to be limping.

The investigator remained on the scene, but observed no further

activity before his departure at about 4 PM.          Two days later, the

investigator reported that Gross "jogged down the sidewalk" to her

car before driving her stepdaughter to school.

D.   The Independent Medical Examination ("IME")

            On February 22, 2007, the last day of video surveillance

and the day after Gross had driven to the hospital to see her

mother,    an   IME   was   conducted   at   Sun   Life's   request   by   a




      23
       Sun Life states in its brief that Gross made the return trip
without stopping. Although that may be a fair inference from the
record, Gross correctly notes that the investigator did not
explicitly say that she did not stop.     Despite stating that he
"followed [Gross] approximately the same distance back towards her
residence," he evidently lost sight of her at some point because,
when he arrived at her residence, her car was already parked and
she had entered her home.

                                   -40-
neurologist, Dr. Rukmaiah Bhupalam.24    The investigator observed

Gross walk with a limp as she left home that morning for the

appointment and, when she emerged from the doctor's office more

than four hours later, she was seated in a wheelchair pushed by her

husband.    Once they reached home, Gross's husband opened the car

door for her, though she stood up without assistance.   The couple

embraced before walking arm-in-arm up the driveway toward the

house. About halfway to the front door, Gross's husband held on to

her right arm as she walked, with a slight limp, the remaining

distance.

            In his initial report of the IME, dated March 19, Dr.

Bhupalam stated that Gross's husband had "to assist her to move

from [a] chair to the bed as she appeared to be in significant pain

and she could not use her right hand."    Gross told Dr. Bhupalam

that "she is usually able to walk 6 hours after she changes her

Duragesic patch [pain medication delivered through the skin], and


     24
       This independent evaluation was recommended by Dr. James
Sarni, a Sun Life medical consultant who had reviewed the
information in Gross's chart. Dr. Sarni noted that

     the documentation does not strongly support a diagnosis
     of reflex sympathetic dystrophy or complex regional pain
     syndrome. . . .

     Therefore, it would be helpful if this patient were to be
     evaluated by a neurologist who would have experience in
     treating migraine headaches. Any neurologist should be
     able to comment intelligently upon the right upper
     extremity and whether or not they believe it is
     consistent with complex regional pain syndrome or RSD and
     what steps could be taken to both diagnose and treat it.

                                -41-
she can function better for approximately 10 to 12 hours after that

and again she goes downhill." The doctor stated that Gross's "main

difficulty is ambulating because of pain and also use of her right

hand."   He diagnosed Gross with, inter alia, chronic fibromyalgia

and "probably complex regional pain syndrome," but speculated that

"emotional    factors   .   .   .   could    be   contributing   to   her   pain

symptomatology," and recommended that she be seen by a behavioral

specialist or mental health professional.                In conclusion, Dr.

Bhupalam stated that Gross is "unable to return to [her] prior

occupation and is totally disabled even for sedentary work even on

a part time basis."

             Immediately after receiving Dr. Bhupalam's report, Sun

Life sent him copies of the video surveillance.            After viewing the

recordings, the physician changed his assessment:

             [I]t does appear that she can function very
             well without any difficulty and appears
             neurologically normal even the day before my
             examination.   On the day of examination she
             was limping even in the videotape however,
             this appears to be a functional component.
             Based on the observation in the video tape,
             especially on the day before, and also to
             previous videotapes in January and November, I
             do feel that she can function quite well and
             probably will be able to return to her
             previous occupation as a manager in a multi
             physician opthalmology and optometric office.
             However, a re-evaluation might be beneficial.
             It does appear that she can use both upper and
             lower extremities quite well and her gait also
             appears to be normal, and she does not appear
             to be in any pain or discomfort in the video
             recorded on February 21, 2007 just a day
             before my evaluation in the office. Even on

                                      -42-
            the videos that were done in November and
            January, it appears that she can function
            quite well, based on my review of the video.

Following Dr. Bhupalam's examination, Sun Life obtained a paper

review of Gross's medical records from another medical consultant,

Dr. William Hall, who likewise noted that the surveillance videos

undermined   Gross's   subjective      reports    of    pain   and   functional

limitations.

E.   Sun Life's Benefits Decisions

            In a seven-page letter dated April 23, 2007, Sun Life

notified Gross that it had denied her benefits claim because of

"insufficient objective evidence to substantiate" a disability that

precluded her from performing her duties at Pinnacle.                The letter

cited to the surveillance evidence, which in Sun Life's view

demonstrated "a capacity for activity that far exceeds" the limits

described    in   Gross's   claim    forms.      The   insurer   specifically

referred to Dr. Bhupalam's reports, and it quoted from Dr. Hall's

file review.      Dr. Hall's evaluation highlighted the absence of

"[c]onsistent and abnormal objective physical and neurological

findings," other than the doctors' reports of swelling, temperature

variation, perspiration, and discoloration of her right arm.                 He

further noted that, while Gross's medical records "provisionally

support diagnosis of RSD right arm and hand," the surveillance

video   "compellingly       weighs     against"        that    diagnosis    and

corresponding activity restrictions.


                                     -43-
             Gross filed an appeal of Sun Life's decision, which she

supported with results of a fourth functional capacity evaluation

by Dr. Egan.25        In that November 2007 report, the doctor again

diagnosed CRPS in the right arm, fibromyalgia, severe migraines,

and chronic fatigue, as well as depression.                She observed that

Gross's right arm was colder and discolored, "as is seen in complex

regional pain syndrome," and that Gross "can hardly raise her arm."

She further reported that Gross spends most of her day in bed or on

a   recliner   and    that    "[a]ctivity    leads    to   worsening   pain."

Predicting     that   Gross    was   "unlikely   to   improve,"   the   doctor

summarized her conclusions as follows:

             She has had symptoms for many years.        No
             medication or other modality has made her able
             to function well enough to have a life at home
             much less at work. With these diagnoses, she
             is unlikely to get to the point she will be
             able to work.

             Dr. Egan stated that Gross was limited to sitting and

standing for no more than one hour per day, and that she could

neither push nor lift any weight.            The physician also noted that

Gross's work capacity was further limited by the effects of four

prescription medications, which left her tired or with trouble

thinking, or both.




      25
       Gross submitted a forty-seven page letter to Sun Life in
December 2007, which, inter alia, reviewed evidence that she
previously had submitted and described the results of Dr. Egan's
most recent assessment.

                                      -44-
             Sun Life rejected the appeal on January 23, 2008.             Its

letter of explanation relied heavily on a report from a third-party

medical consultant, who had performed a paper review of Gross's

medical file earlier that month.         The physician, Dr. Alan Neuren,

noted "the marked dichotomy between [Gross's] reported appearance,

behavior, and findings when seen by healthcare providers . . .

compared with her appearance under surveillance," and asserted that

"[t]he only reasonable conclusion" to be drawn "is that she has

deliberately      embellished   her    symptoms    to   her   providers    for

secondary gain."      Invoking the multiple medical reports that had

questioned the medical support for, and thus the veracity of,

Gross's complaints, Sun Life stated that "[t]he severe restrictions

and limitations, as noted by Dr. Egan on . . . September 23, 2006,

are clearly not credible when viewed in light of Ms. Gross'

demonstrated functional capacity on the surveillance video."               The

insurer thus found "no basis on which to conclude that Ms. Gross

would be unable to perform the Material and Substantial Duties of

her Own Occupation."

F.   Discussion

             Gross argues primarily that Sun Life gave unjustified

weight to the surveillance videotapes.              She asserts that the

insurer wrongly depicted the activity seen during the surveillance

as inconsistent with the physical limitations determined by the

physicians    and   physical    therapist    who   examined   her,   and   she


                                      -45-
emphasizes that the episodes highlighted by Sun Life constituted a

small percentage of the time she was observed. With respect to the

long-distance driving in particular, she objects to Sun Life's

failure to take into account -- and inform its medical consultants

about -- her mother's poor health and medical emergency. Sun Life,

meanwhile,    insists     that   the    surveillance       videotapes    provide

substantial evidence in support of its denial of Gross's claim, and

it highlights the absence of objective evidence in support of her

proffered diagnoses and limitations.

             In considering these arguments, we initially put to one

side the video surveillance, considering its impact only after

examining the medical evidence.

             1. Medical Analysis

             We   have   no   difficulty      concluding    that   the   medical

evidence in the record, if credited, is adequate to prove Gross's

entitlement to disability benefits. Her long history of migraines,

extreme fatigue, and widespread muscular pain is well documented,

and the progressive weakness and numbness affecting her right arm

and hand are also supported by numerous medical reports.                 Without

exception, the doctors who examined her viewed her symptoms to be

consistent with RSD, CRPS, fibromyalgia, or more than one of those

illnesses. Although many of Gross's physical complaints may not be

readily susceptible to objective confirmation, findings of chronic

for lack of confirmable symptoms.                See, e.g., 

(Lipez, J., dissenting) ("Our court has emphasized before that

in dealing with hard-to-diagnose, pain-related conditions, it is

not reasonable to expect or require objective evidence supporting

the beneficiary's claimed diagnosis."); 

(recognizing that "fibromyalgia is a disease that is diagnosed

primarily based on a patient's self-reported pain symptoms");

("We have previously found it unreasonable for an insurer to

require objective evidence to support a diagnosis of a condition

that is not subject to verification through laboratory testing.").

              Importantly, however, the record here includes objective

evidence, as well as the recognition by Sun Life's own medical

consultant, Dr. Hall, that Gross's "musculoskeletal symptoms, as

presented      by    her,    are    credible     to   treating     and   consulting

physicians."        Indeed, Dr. Hall wrote that the medical records he

had   reviewed       "support      her   reported     subjective    symptoms,     and

provisionally support diagnosis of RSD right arm and hand."                       For

example, each of the medical professionals who examined Gross found

her   right    arm    to    be   visibly   abnormal     in   one   or    more   ways,

including: reddened, blue or purplish, swollen, "profuse sweating,"

shiny, cool to the touch, or with "increased temperature to touch

vs. the left."             Multiple doctors viewed these distortions as


                                          -47-
symptomatic of RSD or CRPS.26          In addition, the physical therapist

who performed her FCE, Chris Kaczmarek, noted that the "[g]eneral

muscle tone of the right upper extremity and bilateral lower

extremities was . . . hypotonic."27

           Moreover, not only did the examining doctors uniformly

perceive   her   complaints       of   pain   and   limited    capacity    to   be

credible, but Kaczmarek also reported that, when undertaking tasks

for the FCE, Gross was cooperative and "willing to work to maximum

abilities in all test items."            He further observed that Gross's

"perceived abilities . . . are consistent with client's functional

abilities objectively identified during the FCE."                  His assessment

that she "gave maximal effort on all test items" was based on his

observations     of   "predictable      patterns     of    movement     including

increased accessory muscle recruitment, counterbalancing and use of

momentum, and physiological responses such as increased heart

rate."     These      objective    indicators       of    effort    diminish    the

possibility that Gross was deliberately "failing" the capacity test

and lend weight to Kaczmarek's report that Gross was "physically

unable to perform" a range of tasks.          Medical notes from various

doctors show that her weight dropped by about thirty pounds between

October 2005 and March 2007.

             Gross's good faith in describing her limitations is also

reinforced by letters from her co-workers and employers -- not

mentioned in either of Sun Life's denial letters -- describing her

persistence     in   continuing   to   work   despite   obvious   pain   and

compromised physical capacity.         Indeed, contrary to Sun Life's

assertion in its initial denial letter that Gross chose to stop

working,28 Pinnacle's Paul Wedge told the insurer that "[w]e stopped

her from working when we received her doctor orders that she was

not fit to work."     In a "To Whom It May Concern Letter" written in

February 2007, the general manager of the optometry practice where

Gross worked described the "steady decline in the use of her arms

and legs for nearly nine months."29       Simply put, this does not seem


     28
          The pertinent paragraph in the denial letter was as follows:

     Therefore, it does not appear that you would be eligible
     for Total Disability benefits, Partial Disability
     benefits or benefits under the rider attached to your
     policy based on our thorough review of all of the
     medical, occupational and other information in the claim
     file. Rather, any loss of income appears to be as a
     result of a choice to stop working for your Employer and
     not as a result of any change in restrictions and
     limitations that would prevent you from performing a
     light occupation.
     29
        Gross's boss, Mike Feeney, elaborated in his letter as
follows:

     Countless times I spoke with Diahann about the need to

                                   -49-
to be the history of a person seeking to exaggerate her illnesses

to avoid working and obtain disability pay.      Cf. Gannon v. Metro.

Life Ins. Co., 

, 213 (1st Cir. 2004) (observing that

claimant's performance during FCE was inconsistent and she "did not

put forth her maximum effort during the tests").

            Of course, the medical evidence is not entirely favorable

to Gross.   All of her diagnostic tests, including a bone scan that

is sometimes used to diagnose RSD, were negative, and Dr. Bhupalam

noted that "there is no definitive evidence" for that syndrome.

Dr. Hall noted that neither Gross's "symptoms nor varying right arm

or hand findings explained by appropriate MRI, CT, radioisotope or

electrophysiologic    findings   or     by   hematologic,   metabolic,

endocrinologic or renal testing."     Dr. Coates pointed, inter alia,

to Gross's report that her Fentanyl pain-relief patch inexplicably


     take time off, to take care of herself before the job
     responsibilities. Stubborn is not a strong enough term
     each time she told me to mind my own business.       She
     wasn't going to give in until she absolutely had to. She
     never lacked in doing a great job in the office.      It
     wasn't until early May of 2006 when I witnessed her fall
     in the office, that I felt I could do something to try
     and help. That day after falling, she couldn't use her
     legs and get up.     Dr. Baier (staff Optometrist) and
     myself assisted her up into a chair, and I refused to
     take no for an answer. The two of us drove her home,
     helping her into her home. I did not allow her back into
     the office until she obtained a doctor's note releasing
     her for work.    She gave me that on May 10, 2006 and
     returned.

Another letter, from Dr. Baier, noted that, in August 2006, "Ms.
Gross finally succumbed to the advice of her physicians, family,
friends and co-workers and terminated her employment."

                                 -50-
wore off "in what would normally be the middle of the dosing."                      The

doctors who performed physical examinations speculated that the

severity     of     her    symptoms   might       be   attributable    in    part    to

psychological factors and recommended that she obtain counseling or

behavioral treatment.              See, e.g., App. at 416 (Dr. Egan, in

September 2006, stating that she believes "a lot of the problem is

depression" and that Gross "needs to see a psychiatrist"); 

Coates in March 2007); 

Witt); 

Bhupalam).           She did not do so.

              Nonetheless, even with negative tests and some puzzlement

over the extent of her reported pain, doctors continued to diagnose

her   with    RSD    and     fibromyalgia.         The   negative     bone   scan    --

emphasized by Sun Life -- is not decisive.                     A CRPS fact sheet

prepared by the National Institute of Neurological Disorders and

Stroke ("NINDS"), a 2007 version of which is contained in the

record,      reported       that   "CRPS    is    diagnosed    primarily     through

observation of the signs and symptoms" and stated that "there is no

specific diagnostic test for CRPS."                    R. 03359.    The NINDS fact

sheet further explained:

              [T]he most important role for testing is to
              help rule out other conditions.           Some
              clinicians apply a stimulus (such as touch,
              pinprick, heat, or cold) to the area to see if
              it causes pain. Doctors may also use triple-
              phase bone scans to identify changes in the
              bone and in blood circulation.

Id.30        The repeated referrals to counseling also reflect common

practice in treating CRPS.31

                In sum, the sustained and progressive nature of Gross's

complaints, their facial credibility to the medical practitioners

who personally examined her, and the objective symptoms consistent

with RSD -- given the absence of any method for reaching a

conclusive diagnosis -- support a finding of total disability. Cf.

n.4 (observing that the claimant arguably

would be unable "to fool so many doctors over so many years if

there were little or no serious pain").          The narrative changes,

however, with the addition of the surveillance evidence.

       The current NINDS fact sheet lists psychotherapy as one form
of treatment for relieving the symptoms of CRPS. It states:

        CRPS and other painful and disabling conditions often are
        associated with profound psychological symptoms for
        affected individuals and their families. People with
        CRPS may develop depression, anxiety, or post-traumatic
        stress disorder, all of which heighten the perception of
        pain and make rehabilitation efforts more difficult.
        Treating these secondary conditions is important for
        helping people cope and recover from CRPS.

evaluation before the initial rejection of Gross's claim, reveals

the impact of the surveillance evidence on Sun Life's decision to

deny benefits.       Although Dr. Bhupalam's examination of Gross and

her medical history had led him to conclude that Gross "is totally

disabled even for sedentary work even on a part time basis," the

videotapes led him to the opposite conclusion: "I do feel that she

can function quite well and probably will be able to return to her

previous occupation as a manager in a multi physician ophthalmology

and optometric office."

             Dr. Neuren, whose paper review of Gross's file was the

final medical assessment before Sun Life's second rejection of her

claim, similarly placed substantial weight on the videotapes.                  He

noted   "the   marked     dichotomy     between      her   reported   appearance,

behavior, and findings when seen by healthcare providers (her own

treating   physicians,        along   with     Dr.    Bhupalam     and   therapist

Kaczmarek)     compared    with   her    appearance        under   surveillance."

Addressing the one objectively manifested symptom noted by all

examiners,     Dr.   Neuren    stated    that     "[t]he    reported     sweating,

redness, etc. can be self induced and may have been in this

instance."     Dr. Neuren opined that the inconsistencies between

Gross's "observed activities while under surveillance and her

appearance in the physicians' offices are . . . indicative of

symptom embellishment," and he concluded that "[i]t is obvious that

there has been no loss of function."


                                        -53-
          We have long recognized that even limited surveillance is

a useful way to check the credibility of individuals who claim

disability based on symptoms that are difficult to evaluate through

objective tests.   See, e.g., 

("We have

permitted ERISA plan administrators to use this type of sporadic

evidence in the past."); 

(recognizing that

insurer could properly use an investigator's report and photographs

in making the benefits determination); Tsoulas v. Liberty Life

Assurance Co., 

, 80 (1st Cir. 2006) (approving insurer's

reliance on both surveillance evidence and medical advice).    Where

the activities captured on video directly contradict a claimant's

asserted limitations, and there is no definitive evidence of a

disabling condition, the surveillance alone could provide adequate

support for a denial of benefits.     See, e.g., 

-30 (noting that the insurer "reached its decision not because

it failed to consider the evidence in [claimant's] favor, but

because it determined that the surveillance results undermined the

credibility of important portions of that evidence"); 

(affirming denial of benefits where claimant stated,

inter alia, that she could not walk or stand without assistance and

spent fourteen to eighteen hours in bed each day and surveillance

showed her walking without assistance and "traveling to a hotel, a

parking garage, a restaurant, a comedy club, a night club, and back

to the hotel on a single day").


                               -54-
           Sun Life maintains that this is such a case.           On this

record, under a de novo standard of review, we cannot agree.            In

our view, the most significant incompatibilities between Gross's

reports   and   her   observed   functional   capacity   arise   in   three

episodes recorded by the investigator: the two lengthy drives to

see her mother, and the evening shopping excursion to Kmart in

which Gross was seen in a short span of time reaching over her

head, bending, and kneeling, with "no signs of guarded motion."

Without these more ambitious activities, the remainder of the

observations cited by Sun Life -- Gross's jogging a few steps on

two occasions, driving short distances for errands or appointments,

and walking without limping or other signs of pain -- could be

dismissed as day-to-day variations in physical ability related,

inter alia, to fluctuations in her level of fatigue and the timing

of pain medications.     Indeed, even the ninety-minute drive to her

mother's home on the morning of November 9, 2006 was within the

limitations specified by Dr. Egan, who reported that Gross could

not sit or drive for more than that amount of time.       Notably, Gross

stopped at a rest area one hour into the trip, and it is not known

when she drove home.     The investigator left while Gross was still

at her mother's home, and no surveillance took place the next day.

           The trip to Kmart on January 11, which spanned an hour

door-to-door in the early evening, is more at odds with Gross's

reported limitations.       Though accompanied by her stepdaughter,


                                   -55-
Gross was seen reaching for an item above her head, bending down to

the lower level of the shelves, and kneeling to examine other

items.   Once at home, Gross carried two plastic bags as well as her

purse from the car to the house.    All of these movements occurred

with no reported hesitancy or instability.    According to physical

therapist Kaczmarek, however, Gross reported a week later that "she

tolerates short bouts of activity for less than a few minutes," and

that she has "difficulty walking with frequent falls."     Based on

his testing, Kaczmarek concluded that Gross had "[p]oor standing

balance," "[u]nstable gait pattern requiring assistance of device

or hand held assistance," and "[i]nability to get into and out of

positions such as crouching, kneeling, squatting, crawling."

             The 120-mile round-trip drive on February 21 from her

home to the medical center in Ashland, Kentucky, is particularly

troubling.     Before setting off on the trip, Gross pumped gas,

"us[ing] her right hand to hold the gas nozzle in her gas tank."

She then drove for an hour before stopping at a rest area, where

she was observed "walk[ing] quickly and show[ing] no signs of

guarded motion."      When she exited the restroom, she was seen

walking quickly to her vehicle and taking two jogging steps before

entering the car.      She drove for another hour to the medical

center, arriving at about 1:30 PM, and two hours later made the

return trip home -- possibly without a rest stop along the way.

Gross's activity on this day was singled out by Dr. Bhupalam in his


                                -56-
revised assessment of her ability to work. Her manipulation of the

gas pump is especially noteworthy given her reports of pain and

numbness and "little functional usage" of her right hand.

               Dr. Bhupalam also noted, however, that "a re-evaluation

might be beneficial" -- an observation we understand to suggest

that the video surveillance, while damaging to Gross, did not

necessarily undermine her claim.      Indeed, the record does not show

that either Dr. Bhupalam or Dr. Neuren knew that Gross's travel to

the medical center in Ashland was in response to a phone call

reporting that her mother had experienced a medical emergency,

possibly a heart attack.       Dr. Neuren, in fact, commented in his

report that "[i]t is unclear who the claimant was seeing [at the

medical building in Ashland] or why she would need to travel so far

to be seen."        We consider knowledge of the reason for Gross's

unusual travel that day essential for any reliable appraisal of her

medical condition.       Individuals often rise to the occasion in the

event of an emergency. Hence, on the current record, we are unable

to judge whether Gross's condition and physical limitations, as she

reports them, are necessarily inconsistent with her activities that

day.        In context, the extra driving, the hurried movements, the

pumping of gas may have been at the far edge of what she could

manage with the aid of medication in the face of a family crisis.32


       32
       Gross reported to two different doctors in March 2007 that
she retained at least some use of her right arm. She told Dr.
Coates that she could lift her arm slightly after changing her pain

                                   -57-
In addition, the pain and functional limitations observed by Dr.

Bhupalam during his examination of Gross the next day might

possibly have been the price she paid for those actions, supporting

her claim that she could not handle such activities on a daily

basis.    It is also noteworthy that on February 23, two days after

the trip and the day after the doctor's visit, the investigator

observed no activity by Gross.

            Sun Life's handling of the inconsistencies between the

medical reports and the video surveillance -- specifically its

apparent failure to provide important context to Dr. Bhupalam and

its internal reviewers -- raises a legitimate question about

whether Sun Life has made a bona fide effort to determine Gross's

capabilities.      On de novo review, we have no choice but to remand.

As the record now stands, we are unable to resolve the debate

between    the    parties   on    the    significance    of   the   surveillance

evidence.        Although the medical evidence in Gross's favor is

impressive, it is not monolithic and the surveillance results

diminish    its    force.        The    capabilities    documented    on   video,

particularly on January 11 and February 21, require us to look more

skeptically at Gross's self-reported complaints of constant pain,

fatigue, and limited function.            Yet, we are unwilling to disregard

the evidence in her favor without any contextualized assessment of




medication patch, and she told Dr. Bhupalam that she felt the
"right upper extremity" is "almost useless almost 95% of the time."

the most significant departures from her professed limitations.

See Marantz v. Permanente Med. Grp, Inc. Long Term Disability Plan,

,    329   (7th   Cir.    2012)    ("[T]he      weight   given   to

surveillance evidence of this type depends both on the amount and

nature of the activity observed."); 

(same).

              We     recognize    that    Gross    bears    the   burden   to   prove

disability.        Moreover, as Sun Life pointed out in rejecting her

appeal, she did not submit a statement from her own doctor refuting

Sun Life's assertion in its original denial letter that the

surveillance "show[ed] a capacity for activity that far exceeds"

the limitations she claims.                This omission highlights what we

regard as the open question: the effect that the surveillance

evidence, when viewed in context, may have on other evidence

indicating disability.33

              Hence, as in Maher, we cannot "say with assurance that

[Sun Life] denied [Gross] benefits to which she was entitled," but

we    also    have    doubts     about   Sun     Life's    justification    for    its

parties can further address both the significance of the video

        Relatedly, we note that Dr. Neuren's assertion that the
physical abnormalities affecting Gross's right arm could have been
self-induced is unexplained and thus provides dubious support for
his conclusion that Gross likely exaggerated her symptoms. This
gap, too, can be explored in future proceedings.

condition of her right arm.        Cf., e.g., 

(ordering remand to the claims administrator for a new review);

Quinn v. Blue Cross & Blue Shield Ass'n, 

, 477 (7th

Cir. 1998).

           To recap, we hold that Pinnacle's disability policy was

a component of a benefits plan governed by ERISA and that the

applicable standard of review for benefits claims under the plan is

de novo.   Applying that standard to the evidence currently in the

record, we cannot determine whether Sun Life justifiably rejected

Gross's disability claim on the basis of the surveillance video and

the likelihood of symptom embellishment, particularly relating to

her right arm.

           We therefore vacate the judgment appealed from and remand

the case to the district court, with directions that it remand the

matter to Sun Life for proceedings consistent with this opinion.

The insurer, as plan administrator, will have the opportunity to

address    the   concerns   that    we    have   identified,   i.e.,   the

significance of the video evidence in assessing Gross's limitations

and the veracity of her self-reported and observed symptoms.

Gross, in turn, must be given the opportunity to respond.          Before

the district court enters its remand order, it should hear from the

parties on whether to allow the record to be supplemented beyond

those specific inquiries.          We leave to the district court's

administrative process goes forward.   We take no view as to the

outcome of the further proceedings to be held on remand.
