Before LUCERO, SEYMOUR, TACHA, Circuit Judges.


SEYMOUR, Circuit Judge.
      Jason Fowler appeals the district court’s determination that the United

States was entitled to summary judgment on a tort action he filed against the

United States and an employee of the U.S. Air Force, Sean Garrick. We reverse.

                                         I.

      On June 4, 2006, in Boulder County, Colorado, Mr. Fowler was injured

when a car driven by Sean Garrick collided with Mr. Fowler and his motorcycle.

Mr. Garrick was an active-duty member of the U.S. Air Force, stationed at

Buckley Air Force Base in Aurora, Colorado. He was in Boulder County 1 for a

three-day temporary duty assignment (“TDY”).

      On his TDY assignment, Mr. Garrick worked twelve-hour shifts (7 a.m. to

7 p.m.) for three consecutive days. He was required to report for duty thirty

minutes before his shift began. He was also required to rest for at least eight

hours before each shift. Mr. Garrick testified that these shifts are demanding; at

the end of the twelve-hour shift, Mr. Garrick would be “pretty much too tired to

do anything else besides eat and sleep.” Dep. of Garrick, Aplt. App. at 291.

      The Air Force provided Mr. Garrick, and other employees assigned to the

Boulder Facility, with hotel accommodations during TDY. 2 While on this

      1
        Out of concerns for national security, the precise location of Mr.
Garrick’s temporary duty assignment has not been disclosed. We will refer to it
as the “Boulder Facility.”
      2
       Although the Air Force employees were not forced to stay at the hotel,
Sgt. Derick Lucas, Mr. Garrick’s commanding officer, testified that he knew of
only one employee assigned to the Boulder Facility who did not stay at the hotel.

assignment, Mr. Garrick was also eligible for a per diem allowance and mileage

reimbursement for the cost of travel between Buckley and the Boulder Facility.

Although Mr. Garrick could have stayed in the hotel the night before his shift

began, he instead spent the night of June 3rd in Aurora. The next morning, he

drove the hour and fifteen minute commute to the Boulder Facility for his shift.

      The accident occurred on the first day of Mr. Garrick’s TDY. Shortly

before 1:00 p.m., Mr. Garrick’s commanding officer, Sergeant Lucas, authorized

Mr. Garrick to go on a break until 2:30 p.m., so that an Air Force reservist could

use his work station. During these breaks, the Air Force does not require

employees to spend their time in specific ways, but typically when employees

“get a break, they just go and relax at the hotel.” Dep. of Sgt. Lucas, Aplt. App.

at 306. Mr. Garrick decided to use his break to go to the hotel and sleep. During

the break, Mr. Garrick continued to be “on duty.” On his way to the hotel, Mr.

Garrick and Mr. Fowler were in a car accident with each other. After the

accident, Mr. Garrick was picked up by a co-worker and returned to the Boulder

Facility to complete his shift.

      Mr. Fowler filed suit against Mr. Garrick and the United States under the




That employee lived in Boulder County, near the Boulder Facility. To his
knowledge, everyone else assigned to the Boulder Facility would stay at the hotel.

Federal Tort Claims Act (“FTCA”). 3 28 U.S.C. § 1346(b). Mr. Fowler contended

the United States should be liable for the collision because it “is liable for the

negligent acts of its employees committed in the scope and course of their

employment.” Complaint, Aplt. App. at 9 (citing 28 U.S.C. § 1346(b)). He also

alleged state law claims against Mr. Garrick.

      The Federal Employees Liability Reform and Tort Compensation Act of

1988, 28 U.S.C. § 2679, commonly known as the Westfall Act, “accords federal

employees absolute immunity from common-law tort claims arising out of acts

they undertake in the course of their official duties.” Osborn v. Haley, 

, 229 (2007) (citing 28 U.S.C. § 2679(b)(1)). Under the Westfall Act, the

Attorney General may certify that the employee “was acting within the scope of

his office or employment.” 28 U.S.C. § 2679(d)(1). If the Attorney General

declines to make such a certification, the employee may petition the trial court “to

find and certify that the employee was acting within the scope of his office or

employment.” 28 U.S.C. § 2679(d)(3). If such certification is granted, the United

States is substituted as defendant in place of the employee, and the litigation is

governed by the FTCA. 28 U.S.C. § 2679(d)(4).

      After limited discovery, Mr. Garrick moved the district court to certify that

      3
        The FTCA waives the United States’s sovereign immunity in civil damage
actions based upon “injury or loss of property, or personal injury or death caused
by the negligent or wrongful act or omission of any employee of the Government
while acting within the scope of his office or employment.” 28 U.S.C.
§ 1346(b)(1).

                                          -4-
he was acting within the scope of his employment, to substitute the United States

as the sole party defendant, and to dismiss him from the case. See 28 U.S.C.

§ 2679. The following day, the United States filed a motion to dismiss Mr.

Fowler’s complaint under Fed. R. Civ. P. 12(b)(1), contending the district court

lacked subject matter jurisdiction over the action because the FTCA requires the

tortfeasor to be within the scope of his employment when the tortious act occurs.

The United States denied that Mr. Garrick was acting within the scope of his

employment at the time of the accident, and argued it should therefore be

dismissed from the lawsuit. It also filed a response to Mr. Garrick’s motion to

certify, pointing out the Attorney General had declined to certify that Mr. Garrick

was acting as a federal employee when the accident occurred. It noted that Mr.

Garrick had the burden to prove otherwise.

      Because both Mr. Garrick’s and the United States’s motions related to Mr.

Garrick’s scope of employment, the court decided Mr. Garrick’s certification and

the United States’s jurisdictional motions together. With respect to Mr. Garrick’s

certification motion, the court stated:

      The Tenth Circuit has adopted the view that “certification, although
      subject to de novo review, is prima facie evidence that an employee’s
      challenged conduct was within the scope of his employment. The
      plaintiff then bears the burden of rebutting the scope-of-employment
      certification with specific facts.” Richman v. Straley, 

,
      1145 (10th Cir.1995). Therefore, Garrick bears the burden to present
      “whatever evidence is necessary to persuade [the Court] that [the]
      . . . alleged act, not found by the U.S. Attorney to be within the scope
      of employment, falls within the scope of employment.” Lyons v.

                                          -5-
      Brown, 

, 610-11 (1st Cir. 1998).

Fowler v. United States, No. 08-cv-02650-PAB-BNB, 

, at *2

(D. Colo. Dec. 28, 2009) (alterations in original) (citations omitted). With

respect to the United States’s motion to dismiss Mr. Fowler’s claim against it for

lack of subject matter jurisdiction, the district court said:

      As the United States points out, “[w]hen reviewing a factual attack
      on subject matter jurisdiction, . . . . [a] court has wide discretion to
      allow affidavits, other documents, and a limited evidentiary hearing
      to resolve disputed jurisdictional facts under Rule 12(b)(1).” Holt v.
      United States, 

, 1003 (10th Cir. 1995). Nevertheless, “a
      court is required to convert a Rule 12(b)(1) motion to dismiss into a
      Rule 12(b)(6) motion or a Rule 56 summary judgment motion when
      resolution of the jurisdictional question is intertwined with the merits
      of the case.” 

Third Circuit noted in CNA v. United States,
      

, 140 (3rd Cir. 2008), a great deal turns on this question
      because Rule 12(b)(6) or Rule 56 would provide more procedural
      safeguards to the plaintiff than does Rule 12(b)(1). For example, a
      district court acting under Rule 12(b)(1) may independently evaluate
      the evidence regarding disputes over jurisdictional facts, rather than
      assuming that the plaintiff’s allegations are true. 

question is intertwined with the merits of the case if
      subject matter jurisdiction is dependent on the same statute which
      provides the substantive claim in the case.” 

.

             . . . [H]ere, both the substantive claim and the jurisdictional
      issue require application of the FTCA. . . . Therefore, and because
      all the parties have relied upon evidence outside the pleadings and
      none has indicated any objection to the Court converting the motion
      to one for summary judgment, the Court shall convert the United
      States’ motion into one for summary judgment.

4 Having thus framed the motions before it, the court concluded:


      4
          The United States did not appeal the district court’s conversion.

                                           -6-
       Here, if Garrick has met his burden of presenting evidence sufficient
       to persuade the Court that he was acting within the scope of his
       employment, then the United States necessarily will have failed to
       establish that it is entitled to judgment as a matter of law.
       Conversely, if summary judgment for the United States is warranted
       here, Garrick will have failed to meet his burden of proof.

       The district court granted the United States’s motion for summary

judgment, dismissed the United States from the case, and denied Mr. Garrick’s

motion for certification. 

Subsequently, Mr. Fowler and Mr. Garrick

filed a joint stipulation for the dismissal, with prejudice, of all Mr. Fowler’s

remaining claims against Mr. Garrick, reserving Mr. Fowler’s right to pursue his

FTCA claim against the United States. Mr. Fowler then appealed the court’s

summary judgment decision in favor of the United States.

       At oral argument before this court, the United States for the first time

asserted that we lack jurisdiction over this appeal because, it said, the Westfall

Act decision made the appeal of summary judgment moot. We ordered

supplemental briefing on this issue. 5


       5
         At oral argument, the United States argued that when the district court
denied Mr. Garrick’s motion to certify scope of employment, “it automatically
dismisse[d] the United States from this case.” Transcript of Oral Argument at 18.
In its supplemental brief, the United States does not appear to take such a
position, but it continues to argue that the summary judgment appeal is moot
because the district court’s Westfall Act ruling found “that Garrick was not acting
in the scope of his employment at the time of the accident . . . . That ruling
became the law of the case. Consequently, this Court cannot grant any effectual
relief to Mr. Fowler.” Aple. Supp. Br. at 7.

                                          -7-
      For the reasons explained below in Part II.B., we conclude that the district

court’s Westfall decision regarding Mr. Garrick did not moot Mr. Fowler’s

appeal. We first address the district court’s decision granting summary judgment

to the United States.

                                         II.

A.    Summary Judgment.

      Summary judgment is appropriate if “there is no genuine issue as to any

material fact and . . . the movant is entitled to a judgment as a matter of law.”

Fed. R. Civ. P. 56(a). “When applying this standard, we view the evidence and

draw reasonable inferences therefrom in the light most favorable to the

nonmoving party.” Simms v. Okla. ex rel. Dep’t of Mental Health & Substance

Abuse Servs., 

, 1326 (10th Cir. 1999). Summary judgment is

inappropriate if a rational factfinder could find in favor of the nonmoving party

based on the evidence presented. See Chasteen v. UNISIA JECS Corp., 

, 1216 (10th Cir. 2000). “We review the district court’s grant of summary

judgment de novo, applying the same legal standard used by the court.” Garrison

v. Gambro, Inc., 

, 935 (10th Cir. 2005).

      Under the FTCA, the government is liable only for tortious acts committed

by employees “acting within the scope of [their] office or employment.” 28

U.S.C. § 1346(b)(1). “Scope of employment” is determined by the law of the

place where the accident occurred. Franklin v. United States, 

,

                                         -8-
1495 (10th Cir. 1993); see also 28 U.S.C. § 1346(b)(1). Accordingly, we examine

Colorado respondeat superior law in this case, as did the district court, to

determine if Mr. Garrick was within the scope of his employment when the car

accident occurred.

      Under Colorado law, “the doctrine of respondeat superior is based on the

theory that the employee acts on behalf of the employer when the employee is

within the scope of his or her employment.” Raleigh v. Performance Plumbing &

Heating, 

, 1019 (Colo. 2006). An employer “is liable only if the

servant’s conduct was in some way caused by an intent to serve his employer’s

interests and connected with his authorized acts.” Grease Monkey Int’l, Inc. v.

Montoya, 

, 473 (Colo. 1995) (en banc) (internal quotation marks

omitted). In general, “the question of whether an employee is acting within the

scope of the employment is a question of fact . . . .” 

.

      Significantly, Colorado courts have long recognized the so-called

“traveling employee” rule. Under this rule, when an employee is “[r]equired to

be away from his home by the duties of his employment, his compensation

covering the expenses necessary and incident to living away from home, any

hazards present in staying at the motel, eating at a restaurant, and in going to and

from these places” are considered incident to the employee’s employment.

Alexander Film Co. v. Indust. Comm’n, 

, 1077 (Colo. 1957) (en

banc). Thus, when a traveling employee “must of necessity eat and sleep in

                                          -9-
various places in order to carry on the business of his master,” the acts committed

by an employee “while lodging in a public accommodation, preparing to eat, or

while going to or returning from a meal” are necessarily incident to, and within

the scope of, his employment. Hynes v. Donaldson, 

, 223 (Colo.

1964). Under this doctrine, the employer may be liable for those acts that “are

necessarily incidental to the employment.” Pham v. OSP Consultants, Inc., 

, 659 (Colo. App. 1999); see also Goettman v. N. Fork Valley Rest., 

, 70 (Colo. 2007) (en banc) (“[U]nder Colorado law, a traveling employee

need not be engaged in the actual performance of work to be considered engaged

in the course of his employment.”).

      The United States offers two reasons why the traveling employee rule

should not apply in this case. First, it contends Mr. Garrick was not “required” to

be away from home, because the Air Force would have allowed him to commute

from Buckley. Second, it asserts that Mr. Garrick’s actions while on the break

were not “necessarily incidental” to his employment.

      The government’s first point is unpersuasive. It offers no support for its

rigid interpretation of the word “required.” Although Mr. Garrick has not pointed

to any cases in which the traveling employee doctrine was extended to an

employee who was working an hour and fifteen minutes away from home, the

facts in this case strongly imply that, for all practical purposes, Mr. Garrick was

required to stay in the hotel near the Boulder Facility. If Mr. Garrick were to

                                         -10-
commute to the Boulder Facility each day, while also completing his shift and rest

requirements, he would have only one hour at home to eat dinner and breakfast,

while also showering and attending to other personal needs. Although commuting

may have been technically possible, staying at the hotel was a practical necessity.

This conclusion is bolstered by the Air Force’s decision to provide meal and

travel reimbursements and lodging for TDY at the Boulder Facility. Cf. 

(“As was done in this case, the master recognized these

necessities [of working away from home] and paid the expenses of lodging.”).

Additionally, apparently all other employees living outside Boulder County made

use of the hotel accommodations. Mr. Garrick’s decision to drive to Boulder

County on the morning of his first shift, and to drive home the evening that his

TDY assignment ended, does not undermine this conclusion. Completing the one

and one-half hour commute once in a day does not make it practical to commute

twice-a-day, between twelve-hour shifts, with eight hours of mandated rest time.

Although the Air Force did not force Mr. Garrick to stay in the hotel, it was

clearly in the Air Force’s best interest that he do so. Reading the facts in the light

most favorable to Mr. Fowler, as we must, we are easily persuaded that Mr.

Garrick was a “traveling employee” for purposes of Colorado law.

      Yet, even as a traveling employee, Mr. Garrick’s actions will fall within the

scope of his employment only if they were “necessarily incidental” to his

employment. See 

court declined to decide whether the traveling

                                         -11-
employee doctrine applied because it determined that Mr. Garrick’s trip to the

hotel to nap was not “necessarily incidental” to his employment. Fowler, 

, at *5 n.2. The United States contends the district court made

factual findings relating to scope of employment which we must review only for

clear error. 6 Because summary judgment may only be based on undisputed facts,

however, such “factual findings,” to the extent they were made, were

inappropriate for summary judgment. See Fed. R. Civ. P. 56(a). If we

characterize the district court’s determination as based on undisputed facts, we

review those conclusions de novo for summary judgment purposes. See, e.g.,

.

      When considering which actions are “necessarily incidental” to a traveling

employee’s job, Colorado courts have broadly construed the scope of

employment. For example, in 

, a New Mexico

employee was in Denver for business meetings, and was involved in an

automobile accident on the way back to his hotel from a business dinner. The

Colorado Supreme Court reversed summary judgment in favor of the employer,

holding there was a question of fact as to whether the employee was within the

scope of his employment. 

Similarly, in 

,


      6
        Such alleged findings include “that Garrick was on a ‘pleasurable frolic of
his own’ that was not ‘necessarily incidental’ to his work and not ‘committed in
the furtherance of his employer’s business.’” Aple. Br. at 13 (quoting Fowler,

, at *5).

                                        -12-
a miner in Colorado on a temporary assignment went to dinner after work one

evening with a co-worker, and then drove with the co-worker while drunk back to

the hotel at 1:00 a.m. The car went off the road, killing the co-worker. 

Supreme Court held that these facts created a reasonable inference that

the driver was acting within the scope of his employment as a traveling employee.

See 

The court also explained, “[I]n Colorado, the question of whether

an employee’s consumption of alcohol is outside of the scope of his employment

depends upon the facts and circumstances of the case.” 

      On the other hand, the Colorado Court of Appeals had previously affirmed

summary judgment in a case in which an out-of-state employee caused a fatal car

accident while driving drunk back to his employer-provided apartment after

leaving a bar. 

. The accident was held to be outside the

employee’s scope of employment because his trip to the bar was not necessarily

incidental to his employment. In its scope-of-employment analysis, the court

emphasized that the outing to the bar began several hours after work had ended,

the outing was for “personal entertainment,” and the tacos the employee ate

outside the bar at 1:30 a.m. were “incidental to the trip to the bar and the late

hour at which [he] left the bar–not to the necessities of employment away from

home.” 

      Reading the facts here in a light most favorable to Mr. Fowler, we conclude

that summary judgment was improperly granted. The United States and the

                                          -13-
district court make much of the argument that Mr. Garrick was free to do

“whatever he want[ed],” during his break, Aple. Br. at 6, “including shopping for

sneakers or washing his car,” 

See also Fowler, 

, at

*5. It matters not what Mr. Garrick could have done, but rather what he actually

did do. “[N]ot every act by an employee working away from home is

compensable: ‘He might rob a bank; he might attend a dance; or he might engage

in other activities equally conceivable for his own pleasure and gratification

. . . .’” 

(quoting Alexander Film 

)

(emphasis omitted)). However, the possibility that an employee could rob a bank

in his free time is not in itself a reason to find that he is outside the scope of

employment when he does not rob a bank. Similarly, the possibility that Mr.

Garrick could have bought shoes during his break is not determinative of whether

his trip to the hotel to nap was within his scope of employment.

      Several factors lead us to conclude that the accident may have occurred

within the scope of Mr. Garrick’s employment: First, there is evidence that Mr.

Garrick was given the break for the benefit of the U.S. Air Force. There were

reservists at the Boulder Facility that day who needed an opportunity to work at

the console Mr. Garrick was using, to gain proficiency with the equipment. If

there had not been extra employees on duty that day, Mr. Garrick may well have

never left the Boulder Facility to take a nap at the hotel. Second, unlike the

accidents in Hynes and Goettman, Mr. Garrick was in the middle of his shift when

                                           -14-
the accident occurred, 7 which is clearly distinguishable from a trip to the bar five

hours after work has ended. Third, although the parties dispute whether Mr.

Garrick intended to benefit the Air Force by napping, Mr. Garrick testified that he

intended to nap so he could return to work refreshed and more alert. His

commanding officer also testified that such breaks help employees to work more

efficiently. Finally, although breaks like the one given to Mr. Garrick are not

frequent, his commanding officer assumed that Mr. Garrick would return to his

hotel because “[u]sually, when they get a break, they just go and relax at the

hotel.” Dep. of Sgt. Lucas, App. at 306.

      The district court emphasized that Mr. Garrick “did not believe returning to

the hotel during his break was part of his duties.” Fowler, 

, at

*5. Such a fact is not determinative of scope of employment under Colorado law.

Colorado courts have found traveling employees to be within the scope of their

employment when eating dinner at a restaurant, even if going to the restaurant

was not part of the employee’s duty. See, e.g., Alexander Film 

         The United States argues that for members of the military, the employee’s
“on-call” status is inapplicable to the scope of employment analysis, since
“[m]ost military personnel are paid on a 24 hour basis and are technically ‘on
call’ at all times.” Aple. Br. at 20 (quoting Pruden v. United States, 

(E.D.N.C. 1973)). The accident at issue in this case, however, occurred when
Mr. Garrick was in the middle of his shift, not while he was off duty. Since we
need not rely on Mr. Garrick’s active military status to determine his scope of
employment under Colorado law, we find this line of cases inapposite. Cf. Flohr
v. Mackovajak, 

(11th Cir. 1996) (concluding a civilian Army
employee acted within the scope of employment when in an automobile accident
driving from a restaurant to the hotel during a business trip).

                                         -15-
1077. The district court erred by construing scope of employment under the

traveling employee doctrine so narrowly. On this record, there is a genuine issue

of material fact as to whether Mr. Garrick was within the scope of his

employment during the accident. We therefore hold that summary judgment in

favor of the United States on Mr. Fowler’s claim was improper as a matter of law.

B. Certification of Scope of Employment under the Westfall Act

      Neither party appealed the district court’s denial of Mr. Garrick’s motion

for certification. The district court correctly noted that both the Westfall

certification and summary judgment motions depend on the same issue–whether

Mr. Garrick was acting within the scope of his employment under Colorado law.

See Fowler, 

, at *3. As we have already explained, the FTCA

waives the United States’s sovereign immunity for tort actions arising from a

“negligent or wrongful act or omission of any employee of the Government while

acting within the scope of his office or employment.” 28 U.S.C. § 1346(b)(1).

In effect, this waiver enables tort plaintiffs to bring actions against the federal

government under a theory of respondeat superior. Wood v. United States, 

, 1125 (1st Cir. 1993) (en banc), abrogated on other grounds by

. The Westfall Act, on the other hand, “create[s] a

type of respondeat superior immunity for federal employees that roughly tracks

the federal government’s respondeat superior liability.” 

the United States is substituted as the defendant in place of the

defendant-employee who “was acting within the scope of his office or

employment.” 28 U.S.C. § 2679(d)(1)-(4).

      Under the Westfall Act, a court must “identify and resolve” any disputed

issues of fact regarding the employee’s scope of employment. Arthur v. United

States, 

, 296 (9th Cir. 1994). If there are disputed issues of fact, the

district court “should hold such hearings as appropriate (including an evidentiary

hearing if necessary), and make the findings necessary” to decide the Westfall

certification question. 

here made no such express findings of fact,

and relied on its summary judgment analysis as the basis for denying Mr.

Garrick’s motion for certification. It declared that “if summary judgment for the

United States is warranted here, Garrick will have failed to meet his burden of

proof [for certification under the Westfall Act].” Fowler, 

, at

*3. It also recognized that under Colorado law, “the question of whether an

employee is acting within the scope of the employment is a question of fact,” 

(quoting 

) (internal quotation marks omitted). The

court then concluded its discussion by stating, “[H]ere, there are no genuine

issues of material fact, and the United States is entitled to judgment as a matter of

law that Garrick was acting outside the scope of his employment when he drove

back to the hotel during a break.” 

granted the United States’s

motion, dismissed the United States as a defendant, and denied Mr. Garrick’s

motion without further analysis. See 

United States contends the district court’s determination under the

Westfall Act that Mr. Garrick was acting outside the scope of his employment

precludes it from being sued in federal court because, under the FTCA, the United

States can only be sued for claims involving employees acting within the scope of

their federal employment. Because no one appealed the Westfall determination, it

argues, this court is without jurisdiction to consider Mr. Fowler’s appeal of the

district court’s similar determination under the FTCA. Its claim is without merit.

      The United States is incorrect in its apparent assumption that the district

court’s Westfall determination dismissed the United States from this action. It

did nothing of the sort. As already explained, the purpose and effect of the

Westfall Act is to protect federal employees, not the federal government. The

effect of the district court’s Westfall determination was to deny Mr. Garrick’s

request for immunity, not to dismiss the United States from this action.

      Because the United States remains a party to this litigation, our review of

the district court’s grant of summary judgment is not moot. “A case is moot when

it is impossible for the court to grant any effectual relief whatever to a prevailing

party.” In re Overland Park Fin. Corp., 

, 1254 (10th Cir. 2001)

(quoting Church of Scientology v. United States, 

, 12 (1992)) (internal

quotation marks omitted). A live controversy continues to exist in this case,

however, because our reversal of summary judgment permits Mr. Fowler to

pursue his tort action against the United States.

                                         -18-
      For the foregoing reasons, we VACATE the district court’s determination

that Mr. Garrick was not acting within the scope of his employment for purposes

of the FTCA and REMAND for further proceedings consistent with this opinion. 8

        We need not and do not consider the district court’s similar determination
under the Westfall Act, as that decision was not appealed. In any event, because
the parties have voluntarily dismissed Mr. Garrick from this case, the Westfall
determination is moot and will not be before the district court on remand.
