                                     Respondent-Appellant Cross-Appellee



                 Appeal from the United States District Court
                      for the Southern District of Texas


Before KING, DENNIS, and OWEN, Circuit Judges.
KING, Circuit Judge:
      The petitioner–appellee, Anthony L. Pierce, was sentenced to death in
1986 in Texas state court for a murder committed during the course of a robbery
in 1977. After exhausting his state-court avenues for postconviction relief in
2007, he sought habeas relief under 28 U.S.C. § 2254 in federal district court.
The district court vacated Pierce’s death sentence and ordered resentencing,
finding that the statutory special issues presented to the jury at Pierce’s
sentencing did not permit the jury to give meaningful consideration and effect
to all of Pierce’s mitigating evidence, as Penry v. Lynaugh, 

(1989),
                                  No. 08-70042

requires. The district court denied Pierce’s other asserted bases for habeas relief
and denied a certificate of appealability (COA).        The State appealed the
resentencing. Pierce, in turn, sought a COA from this court on six of the issues
raised before the district court. We granted a COA as to two of those issues:
Whether Pierce received ineffective assistance of counsel at sentencing, and
whether Pierce was mentally retarded and therefore ineligible for the death
penalty under Atkins v. Virginia, 

(2002).
      We now affirm the district court’s grant of resentencing under Penry.
Because we affirm resentencing on that basis, we do not address whether
Pierce’s ineffective assistance of counsel claim provides an alternate basis for
resentencing. We affirm the district court’s denial of habeas relief and an
evidentiary hearing on Pierce’s Atkins claim. The reasons for these rulings are
explained below.
                              I. BACKGROUND
      The district court’s exhaustive opinion more than adequately documents
the factual background and procedural development of this case. See Pierce v.
Quarterman, No. H-07-1561, 

(S.D. Tex. Sept. 26, 2008). Here,
we recite only the facts and procedure necessary to our analysis of the Penry and
Atkins claims.
      Anthony L. Pierce was convicted of capital murder for the shooting death
of Fred Eugene Johnson, the manager of a Church’s Chicken in Houston, during
a robbery of that restaurant on August 4, 1977. Pierce’s first two convictions
were overturned by the Texas Court of Criminal Appeals (TCCA), in both cases
because the trial court had improperly overruled defense counsel’s challenges to
certain venire members. See Pierce v. State, 

(Tex. Crim. App.
1980); Pierce v. State, 

(Tex. Crim. App. 1985). Pierce was tried
and convicted a third time and sentenced to death in 1986. The TCCA affirmed
the conviction and sentence, Pierce v. State, 

(Tex. Crim. App.

                                        2
                                  No. 08-70042

1989), cert. denied, 

(1990), and denied his application for
postconviction relief, Ex parte Pierce, No. 15,859-03 (Tex. Crim. App. Sept. 19,
2001). On August 29, 2002, Pierce filed a successor state habeas application in
which he contended that he was mentally retarded and therefore ineligible for
the death penalty under Atkins. The TCCA denied the application on April 18,
2007. Ex parte Pierce, No. 15,859-04, 

(Tex. Crim. App. Apr.
18, 2007). Pierce filed a 28 U.S.C. § 2254 federal habeas petition on May 9, 2007,
an amended federal habeas petition on August 30, 2007, and a supplemental
federal habeas petition on July 1, 2008.
      On cross-motions for summary judgment, the district court granted Pierce
habeas relief on one of his sentencing claims, concluding that the special issues
presented to the jury at the sentencing phase did not permit the jury to give
meaningful consideration and effect to all of Pierce’s mitigating evidence, in
violation of Penry. The district court denied the remaining asserted bases for
habeas relief and sua sponte denied a COA on those issues. See Pierce v.
Quarterman, 

. We granted a COA as to Pierce’s claims that
he received ineffective assistance of counsel at the sentencing phase and that
because he is mentally retarded, his execution is precluded by Atkins. We
ordered (and have received several rounds of) supplemental briefing as to these
issues and denied a COA as to all other issues.
                        II. STANDARD OF REVIEW
      This habeas proceeding is subject to the Antiterrorism and Effective Death
Penalty Act (AEDPA), 28 U.S.C. § 2254, because Pierce filed his federal petition
on May 9, 2007, well after AEDPA’s effective date. See Lindh v. Murphy, 

, 336–37 (1997). Under AEDPA, a federal court may not grant a writ of
habeas corpus “with respect to any claim that was adjudicated on the merits in
State court proceedings” unless the state court’s adjudication: “(1) resulted in
a decision that was contrary to, or involved an unreasonable application of,

                                        3
                                  No. 08-70042

clearly established Federal law, as determined by the Supreme Court of the
United States; or (2) resulted in a decision that was based on an unreasonable
determination of the facts in light of the evidence presented in the State court
proceeding.” 28 U.S.C. § 2254(d). A “rule[ ] of law may be sufficiently clear for
habeas purposes even when [it is] expressed in terms of a generalized standard
rather than as a bright-line rule.” Williams v. Taylor, 

, 382 (2000).
The relevant “clearly established federal law” is the law that existed at the time
the state court’s denial of habeas relief became final. See Abdul–Kabir v.
Quarterman, 

, 238 (2007); 

–94. A state
court’s factual findings are “presumed to be correct,” although a habeas
petitioner may rebut this presumption by “clear and convincing evidence.” 28
U.S.C. § 2254(e)(1). We review a district court’s refusal to hold an evidentiary
hearing for abuse of discretion. Clark v. Johnson, 

, 765–66 (5th Cir.
2000).
                          III. THE PENRY ISSUE
      The district court vacated Pierce’s death sentence and ordered
resentencing after concluding that the statutory special issues presented to the
jury at sentencing and the prosecutor’s closing arguments regarding those
special issues precluded the jury from giving meaningful consideration and effect
to all of Pierce’s mitigating evidence, as Penry requires. Pierce, 

, at *5. The State appeals, arguing that the special issues in fact
permitted the jury to give meaningful consideration and effect to the mitigating
evidence. The special issues, as prescribed by a now-superseded version of the
Texas Code of Criminal Procedure, were:
      1)    Whether Pierce’s conduct that caused Johnson’s death was
            deliberate and undertaken with the reasonable expectation
            that the death of the victim or another would result; and




                                        4
                                       No. 08-70042

       2)     Whether there was a probability that Pierce would commit
              future criminal acts of violence that would constitute a
              continuing threat to society.
See TEX. CODE CRIM. PROC. ANN., art. 37.071(b) (Vernon 1981);1 see also TEX.
CODE CRIM. PROC. ANN., art. 37.0711 § 1 (Vernon 2006) (noting that superseded
statute applies to offenses committed before September 1, 1991).
A.     The District Court’s Opinion
       The district court summarized the mitigating evidence that Pierce
presented at sentencing as including that: Pierce was young at the time of the
crime (he had turned eighteen just 15 days before); his behavior in prison while
incarcerated at various points both before and after the crime was generally
good; he was not a discipline problem as a child and was honest and respectful
toward his mother and admitted past wrongs to her; he had matured emotionally
and spiritually while in prison; and he had developed intellectually and
creatively while in prison, improving his verbal abilities and making crafts, such
as picture frames and jewelry boxes. Pierce, 

, at *2. The
district court rejected as unreasonable the TCCA’s conclusion that the special
issues permitted the jury to give meaningful consideration and effect to this
mitigating evidence. Noting that “Penry makes clear that jurors must have an
opportunity to fully consider the mitigating evidence as it bears on the broader
question of the defendant’s moral culpability,” 

(alterations and internal
quotation marks omitted), the district court observed:
             On the face of the special issues, the jury could consider some
       of Pierce’s evidence under the future dangerousness special issue.

       1
        Pierce properly preserved his objection to the special issues, arguing at the sentencing
phase that they did not permit the jury to give meaningful consideration and effect to the
mitigating evidence. Pierce requested, but was denied, the following jury instruction:
       You are hereby instructed that you can consider all mitigating circumstances in
       regards to the punishment of the defendant herein. Mitigation will not be
       defined for you; but you may consider the age, race, background, sex, history,
       and all matters related to this defendant that have been put before you.

                                               5
                                       No. 08-70042

       For example, Pierce’s youth at the time of the offense and his
       behavior in prison are relevant to that issue. Other evidence,
       however, is irrelevant, or is only partially relevant, to the future
       dangerousness issue, yet raises questions about Pierce’s general
       moral culpability and character. For example, his honesty and
       respect toward his mother, his willingness to admit past wrongs, his
       efforts to improve himself through education, and his work making
       craft items have little relevance to future dangerousness, but are
       relevant as to his character.

       The district court also held that the “Penry violation was exacerbated by
prosecution comments during closing argument,” which the district court found
“suggest[ed] to the jury that it could not consider Pierce’s mitigating evidence at
all . . . but could consider only whether the State presented sufficient evidence
to merit a ‘yes’ answer to the special issues.” 

court concluded
that “the special issues in this case, especially when considered in light of the
State’s closing argument, violated Pierce’s rights under Penry.” 

Accordingly, the district court vacated Pierce’s death sentence with instructions
that the state court grant a new sentencing hearing or resentence Pierce to a
sentence less than death in accordance with Texas law in effect at the time of
Pierce’s crime.
B.     Pierce’s Additional Mitigating Evidence
       Pierce contends that additional mitigating evidence that he presented at
sentencing and raised in his state habeas application and federal habeas
petition, but that the district court did not discuss in its Penry analysis, provides
further support for the district court’s conclusion.2 Pierce cites the testimony of


       2
         Pierce contends that there was substantial mitigating evidence that his trial counsel
did not present at sentencing. This evidence included that Pierce: was borderline mentally
retarded; was severely abused by his alcoholic father; grew up in extreme poverty in a violent
neighborhood; and suffered from “horrific headaches” and other health problems as a child.
Counsel’s failure to present such evidence, however, does not provide a basis for a Penry claim,
and Pierce does not urge this evidence in support of his Penry claim. “[W]e have held that a

                                               6
                                     No. 08-70042

his mother, Erline Pierce, that he was a good child with few behavioral problems
until he was 13 or 14 years old, when he fell in with a crowd of older boys who
exerted a bad influence. Erline Pierce further testified that, as a result of this
corrupting influence, Pierce was sent to the Texas Youth Council (TYC)3 twice
for extended juvenile detention stays as a young teenager. She commented that
Pierce had been “locked up most of his young life,” so he “couldn’t have a
chance.” Erline Pierce testified that her son had regularly attended church
growing up and “still ha[d] those same beliefs” after his arrest. Finally, Erline
Pierce testified that her son had emotionally matured and improved himself in
prison by furthering his education, developing his reading skills, and developing
his talent for art and woodworking by making jewelry boxes and picture frames
for her.
      Pierce also cites the testimony of Sister Isabella Estrada, a principal for
Holy Cross School in Bay City, Texas. Sister Estrada testified that she got to
know Pierce during his years on death row, and she visited him regularly in the
four years leading up to Pierce’s third trial. She testified that Pierce grew from
being depressed and angry about his situation to being more understanding. As
he developed his ability to speak and articulate his thoughts, Pierce became
more open and able to communicate his feelings.
      Pierce also cites comments by the prosecutor during voir dire that he
asserts “conditioned” the prospective jurors to disregard his mitigating evidence.
In one such instance, the prosecutor stated:




petitioner cannot base a Penry claim on evidence that could have been but was not proffered
at trial.” Miniel v. Cockrell, 

, 338 (5th Cir. 2003) (internal quotation marks
omitted).
      3
        The Texas Legislature changed the name of the Texas Youth Council to the Texas
Youth Commission in 1983.           See Texas Youth Commission, TYC History, at
http://www.tyc.state.tx.us/about/history.html (last visited February 23, 2010).

      Q.    Would you also agree that under our law that the age of an
      individual, whether that be old or young age, in and of itself does
      not give anyone any special rights? Under our law when a person
      becomes the age of 17 they are an adult and are treated as such.
      Would you agree?

      A.   Yes, sir.

      Q. Okay. So in that instance whether a person is 17 or they’re 85,
      the law doesn’t ask how old you are, what color you are, what your
      job is, what your sex is, what your education is, it asks that you
      follow certain norms and those norms determine the interaction
      between human beings and violation of those be tried by a jury if it
      be a criminal. Can you follow that concept in the purposes of our
      law?

      A.   Yes, sir, I believe so.
The prosecutor also sought and obtained the juror’s oral confirmation that if the
juror concluded that the answer to the two special issues was “yes,” he would not
“change one of those answers to no just to prevent the defendant from receiving
the death sentence.”
      Similarly, to another prospective juror, the prosecutor asked:
      Q.      Now, would you agree with me . . . that our law doesn’t
      distinguish as far as finding someone guilty in the law as it relates
      to an individual on the basis of their age or sex, their race or ethnic
      background? . . . I’m saying that our law, as far as making a person
      guilty or being charged with capital murder—like that doesn’t
      distinguish whether or not that person happens to be 17 or 18 or
      black or white or a doctor or what I’m saying is race, sex,
      occupation, ethnic background, as far as whether or not they violate
      the law.

      A.   I agree.

      Q. And would you feel that if the State presented evidence to you
      on Special Issue No. 2 that was beyond a reasonable doubt that the
      answer to Special Issue No. 2 should be “yes” and you found that
      perhaps that individual was a particular age, a young person or so,


                                          8
                                        No. 08-70042

       would you necessarily answer that question “no” because of the age
       or despite what the State showed you?

       A.    No.

       The State contends that the Texas special issues in fact permitted the jury
to give meaningful consideration and effect to all of the mitigating evidence
presented and rejects the proposition that any of the prosecutor’s comments
during voir dire or closing argument could have interfered with the jury’s ability
to do so.
C.     The Legal Framework
       1.     Abdul–Kabir and Brewer
       The Supreme Court most recently addressed the Texas special issues in
Abdul–Kabir, 

, and Brewer v. Quarterman, 

(2007).4
These cases describe the “clearly established law” as it existed in 1999 and 2001,


       4
          Abdul–Kabir and Brewer clarified a long and contentious line of cases in which the
Court grappled with whether the Texas special issues provide a basis for the jury to give
meaningful consideration and effect to mitigating evidence in considering a death sentence.
See Jurek v. Texas, 

(1976) (upholding the facial constitutionality of the Texas
special issues sentencing scheme but leaving room for as-applied challenges); Franklin v.
Lynaugh, 

(1988) (rejecting as-applied challenge, reasoning that evidence of good
prison behavior did not have mitigating significance independent of its relevance to the future
dangerousness special issue); Penry, 

(concluding that habeas relief was
appropriate because the special issues did not provide a basis for jury to give meaningful
consideration and effect to evidence of low IQ, organic brain disorder, abusive upbringing, and
antisocial personality disorder); Graham v. Collins, 

(1993) (declining to decide
whether Texas special issues could give constitutionally adequate effect to mitigating evidence
of good character and youth because law was not clearly established in 1984, when the
conviction become final); Johnson v. Texas, 

(1993) (concluding, on direct review,
that the petitioner’s youth at the time of the crime could be given meaningful consideration
and effect under the future dangerousness special issue); Penry v. Johnson, 

, 799
(2001) (Penry II) (concluding that additional special instruction that allowed jury to nullify
special issues if it concluded that other mitigating circumstances existed was constitutionally
infirm because it “made the jury charge as a whole internally contradictory”); Tennard v.
Dretke, 

, 284 (2004) (rejecting a heightened-relevance standard applied by the
Fifth Circuit that “has no foundation in the decisions of this Court”); Smith v. Texas, 

(2004) (per curiam) (holding that the special issues in combination with general nullification
instruction did not allow the jury to give meaningful consideration and effect to mitigating
evidence of learning disability, low IQ score, childhood abuse, and troubled upbringing).

                                               9
                                       No. 08-70042

respectively, and Abdul–Kabir indicates that the same clearly established law
existed as early as 1990. 

; 

–95. Abdul–Kabir instructs that the relevant state-court judgment for
purposes of review under AEDPA is the judgment adjudicating the merits of the
petitioner’s state habeas 

. The TCCA rejected
Pierce’s petition for habeas relief in 2001. Therefore, the “clearly established
law” described in Abdul–Kabir and Brewer controls this case.
       This circuit has construed Abdul–Kabir and Brewer as imposing a two-part
test to determine whether resentencing is required: First, the reviewing court
must determine whether the mitigating evidence presented by the petitioner
satisfies the “‘low threshold for relevance’ articulated by the Supreme Court.”
Coble v. Quarterman, 

, 444 (5th Cir. 2007).5 If the relevance
threshold is met, the court must determine “whether there was a reasonable
likelihood that the jury applied the special issues in a manner that precluded it

       5
         The Court set out the threshold for relevance in Tennard v. Dretke, 

(2004), commenting:

       [T]he meaning of relevance is no different in the context of mitigating evidence
       introduced in a capital sentencing proceeding than in any other context, and
       thus the general evidentiary standard—any tendency to make the existence of
       any fact that is of consequence to the determination of the action more probable
       or less probable than it would be without the evidence—applies. . . .
       Once this low threshold for relevance is met, the Eighth Amendment requires
       that the jury be able to consider and give effect to a capital defendant’s
       mitigating evidence.

(internal quotation marks omitted). The Brewer majority emphasized that the
focus of the relevance inquiry is not on the “quantity, degree, or immutability” of the
mitigating evidence offered, but rather on whether the evidence, whatever it is, “has mitigating
relevance to the special issues” and “may diminish a defendant’s moral culpability for the
crime.” 

. A footnote of dicta in Abdul–Kabir, however, suggests an
important limitation, stating that no special instruction is required when the “mitigating
evidence has only a tenuous connection—some arguable relevance—to the defendant’s moral
culpability.” 

n.14 (internal quotation marks omitted). An
additional special instruction is necessary only “when the defendant’s evidence may have
meaningful relevance to the defendant’s moral culpability beyond the scope of the special
issues.”

from giving meaningful consideration and effect to all of [the petitioner’s]
mitigating evidence.”         

and Brewer emphasize “the
importance of allowing juries to give meaningful effect to any mitigating
evidence providing a basis for a sentence of life rather than death.”

(emphasis added); accord 

(“[T]he jury must be allowed not only to consider such evidence, or to have such
evidence before it, but to respond to it in a reasoned, moral manner and to weigh
such evidence in its calculus of deciding whether a defendant is truly deserving
of death.”).6 In particular, the Texas special issues will be constitutionally
insufficient as applied when the mitigating evidence presented supports an
“entirely different reason for not imposing a death sentence” than permitted by
the special issues. 

. Abdul–Kabir and Brewer also
indicate that courts should consider whether the prosecutor’s comments to the
jury may have “undermined” the jury’s ability to give meaningful consideration
and effect to all of the petitioner’s mitigating evidence by suggesting that the
jurors may not consider mitigating evidence for relevance outside the special
issues.

       2.      Franklin and Penry



       6
          Before Abdul–Kabir and Brewer, this circuit characterized the standard as requiring
that the jury be able to “fully consider[ ] and giv[e] full effect to all of the defendant’s
mitigating evidence.” Nelson v. Quarterman, 

, 293 (5th Cir. 2006) (en banc)
(citing 

–89). Since Abdul–Kabir and Brewer, this circuit has
concluded that the “meaningful effect” and “full consideration and effect” standards are the
same. See 

n.15 (rejecting the State’s assertion that the “meaningful
effect” standard was less stringent; holding that “[r]egardless of the descriptor attached to it,
the substance of the standard articulated . . . is the same”). This conclusion finds support in
Brewer, where the Court criticized this circuit for applying a “sufficient effect” test rather than
a “full effect” test in evaluating Brewer’s habeas 

. Both parties cite
the “full consideration and effect” formulation from Nelson rather than the “meaningful effect”
formulation from Abdul–Kabir and Brewer. Because this circuit has concluded that the
standards are identical, see 

n.15, we cite the Supreme Court’s
“meaningful effect” formulation.

                                               11
                                  No. 08-70042

      The standard embraced by the Court in Abdul–Kabir and Brewer was first
articulated by Justice O’Connor in her concurrence to Franklin, 

.
In Franklin, the petitioner presented evidence at sentencing that he had
behaved well in prison. 

The plurality opinion concluded that the
future dangerousness special issue provided a sufficient vehicle for the jury to
consider the mitigating evidence. 

The plurality rejected the
petitioner’s contention that an additional instruction was required because the
mitigating evidence of good behavior in prison had relevance beyond the scope
of the special issues. 

The plurality reasoned that “we have never
concluded that States cannot channel jury discretion in capital sentencing” and
rejected the argument that the jury must be able to consider mitigating evidence
for every issue to which it may be relevant. 

concurred with the plurality that the special issues were
constitutionally sufficient as applied because the “petitioner did not suggest that
his lack of disciplinary violations [in prison] revealed anything more positive
about his character” than lack of future dangerousness. 

(O’Connor,
J., concurring). But Justice O’Connor disagreed that the special issues would be
constitutionally sufficient if the mitigating evidence presented in fact had
relevance beyond their scope—for example, to “personal culpability” or
“character.” 

She commented:
      If . . . petitioner had introduced mitigating evidence about his
      background or character or the circumstances of the crime that was
      not relevant to the special verdict questions, or that had relevance
      to the defendant’s moral culpability beyond the scope of the special
      verdict questions, the jury instructions would have provided the jury
      with no vehicle for expressing its “reasoned moral response” to that
      evidence. . . . In my view, however, this is not such a case. The only
      mitigating evidence introduced by petitioner was the stipulation
      that he had no record of disciplinary violations while in prison. . . .
      While it is true that the jury was prevented from giving mitigating
      effect to the stipulation to the extent that it demonstrated positive


                                        12
                                  No. 08-70042

      character traits other than the ability to exist in prison without
      endangering jailers or fellow inmates, that limitation has no
      practical or constitutional significance in my view because the
      stipulation has no relevance to any other aspect of petitioner’s
      character. . . .

             The limited probative value of the stipulation regarding
      petitioner’s lack of prison disciplinary violations is best illustrated
      by the contrasting examples of probative character evidence
      suggested by the dissent. . . . Evidence of voluntary service,
      kindness to others, or of religious devotion might demonstrate
      positive character traits that might mitigate against the death
      penalty. Although petitioner argued to the sentencing jury that his
      prison record demonstrated his lack of future dangerousness,
      petitioner did not suggest that his lack of disciplinary violations
      revealed anything more positive about his character than that.

      The Court adopted Justice O’Connor’s Franklin concurrence in Penry, 

, in an opinion which Justice O’Connor also wrote. There, the majority
concluded that although the deliberateness and future dangerousness special
issues allowed the jury to give partial consideration to the petitioner’s mitigating
evidence of mental retardation and childhood abuse, the Eighth Amendment was
not satisfied because the mitigating evidence had “relevance to his moral
culpability beyond the scope of the special issues, and . . . the jury was unable
to express its ‘reasoned moral response’ to that evidence in determining whether
death was the appropriate punishment.” 

D.    Analysis
      The parties do not dispute that the mitigating evidence that Pierce
presented at his sentencing satisfies the “low threshold for relevance articulated
by the Supreme Court.” 

(internal quotation marks
omitted). Instead, the parties dispute whether the Texas special issues provided
the jury with a basis to give meaningful consideration and effect to the
mitigating evidence that Pierce presented. The State contends that the Supreme

                                        13
                                  No. 08-70042

Court has already ruled, over a series of cases, that the special issues provide
jurors with a meaningful basis to consider all of the types of mitigating evidence
that Pierce presented at sentencing. The State urges that under the Penry line,
the special issues are only inadequate “where the defendant offers evidence of
mental retardation or mental defect or childhood abuse or, perhaps, [childhood]
hardship”—types of evidence that the State contends Pierce did not present in
this case. Pierce counters that the Supreme Court has never taken a categorical
approach to determining whether the special issues provide a basis for giving
meaningful consideration and effect to various types of mitigating evidence, and
he argues that the special issues did not provide such a basis in this case. Pierce
also urges that the prosecutor’s comments to the jury during voir dire and at
closing—which downplayed the mitigating effects of Pierce’s youth and
suggested that the jury lacked discretion to consider mitigating evidence outside
the confines of the special issues—further deprived the jury of a basis for
meaningful consideration of Pierce’s mitigating evidence.
      The first issue is whether the special issues provided a basis for the jury
to give meaningful consideration and effect to each type of mitigating evidence
that Pierce introduced. The second issue is whether there is a reasonable
probability that the prosecution’s voir dire questioning or closing arguments
operated to undermine the jury’s ability to give such consideration. Pierce’s
mitigating evidence falls into the following general categories: youth at the time
the crime was committed, good behavior in prison, troubled childhood, and good
character. We address these categories of mitigating evidence, and the possible
effects of the prosecutor’s comments to the jury, in turn.
      1.    Youth and Good Behavior in Prison
      As the district court recognized, under clearly established federal law, the
future dangerousness special issue provided a meaningful basis for the jury to
consider and give effect to Pierce’s youth—he had just turned 18 at the time of

                                        14
                                 No. 08-70042

the killing—and his good behavior in prison. In Johnson v. 

, the Court held that the future dangerousness special issue gave the jury “a
meaningful basis to consider the relevant mitigating qualities of petitioner’s
youth,” reasoning that
      the signature qualities of youth are transient; as individuals
      mature, the impetuousness and recklessness that may dominate in
      younger years can subside. . . . [T]here is ample room in the
      assessment of future dangerousness for a juror to take account of
      the difficulties of youth as a mitigating force in the sentencing
      determination.

   The Abdul–Kabir majority reiterated that youth “has special
relevance to the question of future dangerousness” because it is “a universally
applicable mitigating circumstance that every juror has experienced and which
necessarily is 

.     The Franklin plurality and
concurrence (a total of five Justices) agreed that the future dangerousness
special issue also allows the jury to give meaningful consideration and effect to
a petitioner’s good behavior in 

–78, 185–86. The Court
has not overruled this precedent. See Garcia v. Quarterman, 257 F. App’x 717,
722 (5th Cir. 2007) (per curiam) (applying Franklin to reject the petitioner’s
Penry claim premised on mitigating evidence of good behavior in prison). The
special issues provided a basis for the jury to give meaningful consideration and
effect to the mitigating evidence of Pierce’s youth and good behavior in prison.
      2.      Troubled Childhood
      Pierce also urges as mitigating evidence his mother’s testimony that he
was a good boy until falling in with the wrong crowd when he was thirteen or
fourteen years old, and that he spent much of his young life “locked up” during
two extended stays in juvenile detention at the TYC. Pierce argues that this is
evidence of a “troubled childhood”—evidence of a type that the Court held in
Abdul–Kabir and Brewer has mitigating relevance beyond the special issues


                                       15
                                  No. 08-70042

because it bears on a defendant’s moral culpability. See 

–57 (noting that evidence of a “rough childhood” has “mitigating force
beyond the scope of the special issues”); 

–94 (finding a
Penry violation because focus on special issues would “necessarily disregard[ ]
any independent concern that, given Brewer’s troubled background, he may not
be deserving of a death sentence”). The State counters that Pierce’s evidence is
different in kind than the “troubled childhood” evidence at issue in those cases
because   those   cases   involved   circumstances   outside   the   petitioner’s
control—such as poverty and childhood abuse—while Pierce’s evidence is limited
to “his self-inflicted problems with the law.”
      The case law does not support the distinction that the State urges. In
Brewer, for example, the Court concluded that an additional instruction was
necessary in order to allow the jury to consider and give effect to evidence that
the petitioner’s “co-defendant, a woman with whom he was apparently obsessed,
dominated and manipulated him,” and that the petitioner had a history of
substance 

–90 (internal quotation marks omitted). The
Brewer majority concluded that there was a reasonable likelihood that the
special issues led the jury to “disregard[ ] any independent concern that, given
Brewer’s troubled background, he may not be deserving of a death sentence,”
and therefore deprived the jury of the opportunity to respond to the petitioner’s
mitigating evidence in a “reasoned moral manner.” 

296. Similarly,
this circuit has held that evidence of a petitioner’s substance abuse might have
“meaningful mitigating relevance beyond its tendency to disprove that [the
petitioner] acted deliberately” and therefore requires an additional instruction.
Garcia, 257 F. App’x at 722 (internal quotation marks omitted). Both of these
cases involved mitigating evidence that was arguably “self-inflicted” (to use the
State’s term), but recognized that this evidence might nevertheless have
mitigating relevance to the petitioner’s moral culpability—and therefore

                                       16
                                 No. 08-70042

relevance outside the special issues. These holdings are consistent with the
requirement that juries be allowed “to give meaningful effect to any mitigating
evidence providing a basis for a sentence of life rather than death.”

(emphases added).          Consistent with these
precedents, Pierce’s evidence of being led astray by older boys and being locked
up for a significant period of time at the TYC had mitigating relevance beyond
the special issues and therefore required an additional instruction.
      3.    Good Character
      Pierce introduced evidence of his good character before the crime,
including that he was kind to his mother, was honest and admitted past wrongs
to her, and regularly attended church. Pierce also presented evidence of his good
character as it developed after he committed the crime. This evidence included
that he had matured emotionally and spiritually while in prison, developing his
ability to speak and articulate his thoughts and becoming more open and able
to communicate his feelings. Pierce also matured in prison by furthering his
education, improving his reading skills, and developing his talent for art and
woodworking.
      In Franklin, five Justices (two concurring, three dissenting) indicated, in
dicta, that the special issues would not allow a jury to give meaningful
consideration and effect to this type of “good character” evidence. Justice
O’Connor’s concurrence stated that although the petitioner’s evidence of good
behavior in prison lacked relevance to any issue other than future
dangerousness, had the petitioner presented “[e]vidence of voluntary service,
kindness to others, or of religious devotion,” an additional instruction would
have been required:
      [i]f [the] petitioner had introduced mitigating evidence about his
      background or character or the circumstances of the crime that was
      not relevant to the special verdict questions, or that had relevance
      to the defendant’s moral culpability beyond the scope of the special

                                       17
                                         No. 08-70042

       verdict questions, the jury instructions would have provided the jury
       with no vehicle for expressing its “reasoned moral response” to that
       

–86 (O’Connor, J., concurring). Justice Stevens’s dissent likewise
emphasized that character evidence of this type “may suggest that the conduct
of which the defendant stands convicted was not in keeping with his or her usual
qualities or traits, a fact that has as much relevance to culpability as to future
dangerousness.” 

(Stevens, J., dissenting).
       Since Franklin, the Court’s jurisprudence on California’s death penalty
statute7 has repeatedly held that character evidence has relevance to a
petitioner’s moral culpability. See, e.g., Ayers v. Belmontes, 

, 15 (2006)
(noting that good character evidence may “extenuate[ ] the gravity of the crime”);
Brown v. Payton, 

, 142–43 (2005) (commenting on the relevance of
good character evidence as a means of “lessen[ing] or excus[ing] a defendant’s
culpability”); Boyde v. California, 

, 382 n.5 (1990) (commenting on
relevance of good character evidence as a means of showing “character strengths
in the face of . . . difficulties” and showing that “criminal conduct was an
aberration from otherwise good character”).8 Evidence of “postcrime character
transformations” is also relevant:
       [T]o accept the view that such evidence could not [be relevant to
       moral culpability] because it occurred after the crime, one would
       have to reach the surprising conclusion that remorse could never
       serve to lessen or excuse a crime. But remorse, which by definition
       can only be experienced after a crime’s commission, is something
       commonly thought to lessen or excuse a defendant’s culpability.



       7
          California’s death penalty statute sets out eleven factors “that the trier of fact shall
take into account . . . if relevant.” Relevant here is factor (k), which instructs the trier of fact
to consider “[a]ny other circumstance which extenuates the gravity of the crime even though
it is not a legal excuse for the crime.” CAL. PENAL CODE ANN. § 190.3(k) (West 2008).
       8
           As a direct appeal, Boyde was not governed by 

.

                                                18

–43; see also 

–16 (noting that it
would be “counterintuitive if a defendant’s capacity to redeem himself through
good works [after the crime] could not extenuate his offense and render him less
deserving of a death sentence”). Ayers and Brown set out the clearly established
law as it existed in 

; 544 U.S. at 139. Boyde was a direct
appeal decided in 1990, well before the denial of Pierce’s state habeas application
became final in 2001. All of these authorities set out the clearly established law
for purposes of this case.
      The Court has addressed good character evidence in the context of the
Texas special issues only once since Franklin, in Graham v. Collins, 

. The State urges that Graham stands for the proposition that the special
issues allow juries to give meaningful consideration and effect to good character
evidence. In Graham, the Court considered the petitioner’s mitigating evidence
that he had a transient upbringing, was a generous person, and “loved the Lord.”

(alterations omitted). The Court stated, in dicta, that the special
issues allowed the jury to give at least some effect to this character evidence, and
indicated that some effect was all that was constitutionally required. 

Graham’s actual holding, however, was that under the law as it existed
in 1984 (the year the petitioner’s conviction became final) the relief that the
petitioner sought would have constituted a new rule, in violation of Teague v.
Lane, 

(1989). 

The Abdul–Kabir majority took pains to
distinguish Graham’s “some effect” language as 

–59, as did
this court in Nelson, in which we rejected the State’s contention that Graham
altered the requirement that the jury be able to give “full consideration and full
effect to the capital defendant’s mitigating 

(“Because




                                        19
                                         No. 08-70042

the [Graham] Court disposed of the case on Teague grounds, it did not address
the substantive merits of the petitioner’s Penry claim.”).9
       Both Abdul–Kabir and Brewer emphasize “the importance of allowing
juries to give meaningful effect to any mitigating evidence providing a basis for
a sentence of life rather than death.” 

(emphases
added).     The California cases establish that good character evidence has
meaningful relevance to moral culpability, which a majority of the Justices in
Franklin indicated is not encompassed by the special issues. These authorities
establish that an additional instruction was required in order for the jury to
consider and give effect to this mitigating evidence.
       4.      Effect of Certain Comments to the Jury
       In Abdul–Kabir and Brewer, the Court indicated that a prosecutor’s
comments to the jury at voir dire and at closing may further impede the ability
of the jury to give meaningful consideration and effect to mitigating evidence.
Pierce complains that the prosecutor, at his sentencing, impressed upon the
jurors in closing argument that they could not consider evidence with relevance
beyond the special issues:
       You each promised me individually that if the State brought you
       evidence that convinced you beyond a reasonable doubt that the
       answers to these special issues would be yes and you knew that a
       “yes” answer to each one of these issues would mean the death


       9
          The State cites several cases from this circuit that cite Graham for the proposition that
“because ‘the principal mitigating thrust of good character evidence is to show that the
defendant acted atypically in committing the capital crime, this evidence can find adequate
expression under the second special issue.’” Bower v. Dretke, 145 F. App’x 879, 885 (5th Cir.
2005) (per curiam) (quoting Barnard v. Collins, 

, 640 (5th Cir. 1992)); see also
Coble v. Dretke, 

, 525 (5th Cir. 2005) (“‘Evidence of good character tends to show
that the crime was an aberration, which may support a negative answer to the special issue
regarding the future dangerousness of the defendant.’” (quoting Boyd v. Johnson, 

, 912 (5th Cir. 1999))), withdrawn and superseded on rehearing, Coble v. Quarterman, 

. But these cases predate Abdul–Kabir and fail to recognize that Graham’s “some
effect” language was dicta that the Supreme Court identified as such in Abdul–Kabir and this
court has since similarly distinguished. See 

, 303.

                                               20
                                  No. 08-70042

      penalty that you would answer those questions “yes” and that you
      would never change your answer despite the evidence in this case
      just so that the death penalty would not be imposed.
      As the district court observed, these comments are very similar (indeed,
nearly identical) to those that the Court criticized in Abdul–Kabir, in which the
prosecutor reminded jurors that they had “‘promise[d’ to] look only at the
questions posed by the special issues, which, according to the prosecutor,
required the jurors to put the petitioner’s mitigating evidence ‘out of [their]
mind[s]’ and ‘just go by the 

. The Abdul–Kabir Court
concluded that these comments had the effect of impermissibly “convinc[ing]
jurors that the law compels them to disregard the force of the evidence offered
in mitigation” that had relevance outside the special issues. 

closing comments in this case are also similar to those
that the Court criticized in Brewer, where the prosecutor urged the jury that
“‘you don’t have the power to say whether [the petitioner] lives or dies. You
answer the questions according to the evidence, much like you did at the guilt
or innocence [phase]. That’s all.’” 

(alterations omitted).
Finding a Penry violation, the Brewer Court concluded that “[t]here [wa]s surely
a reasonable likelihood that the jurors accepted the prosecutor’s argument at the
close of the sentencing hearing that all they needed to decide was whether
Brewer had acted deliberately and would likely be dangerous in the future,
necessarily disregarding any independent concern that, given Brewer’s troubled
background, he may not be deserving of a death sentence.” 

(footnote omitted). To the extent that Pierce presented evidence that could not
be given meaningful consideration and effect under the special issues, the
prosecution’s closing argument may have exacerbated the problem by instructing
the jury to consider only the special issues.




                                       21
                                    No. 08-70042

      Certain of the prosecutor’s comments at voir dire were also problematic.
The prosecutor elicited agreement from one venire member (who was later
selected to serve on the jury) that “under our law . . . the age of an individual . . .
in and of itself does not give anyone special rights,” and that “whether a person
is 17 or they’re 85, the law doesn’t ask how old you are . . . it asks that you follow
certain norms and those norms determine the interaction between human beings
and violation of those be tried by a jury . . . .” The prosecutor elicited agreement
from another venire member (also selected to the jury) that “our law, as far as
making a person guilty or being charged with capital murder—like that doesn’t
distinguish whether or not that person happens to be 17 or 18 . . . as far as
whether or not they violate the law” and the statement that she would not
necessarily answer the second special issue “no” because of the defendant’s age.
The Abdul-Kabir majority observed that comments like these, which “tak[e]
pains to convince jurors that the law compels them to disregard the force of
evidence offered in mitigation,” might “undermine[ ]” a jury’s ability to give
meaningful consideration and effect even to evidence encompassed by the special

. By essentially instructing the venire members that
“youth isn’t relevant,” the comments may have undermined the jury’s ability to
give mitigating effect to evidence of Pierce’s youth through the special issues.
E.    Conclusion
      Under the clearly established law, the special issues provided a basis for
the jury to give meaningful consideration and effect to Pierce’s mitigating
evidence of youth and good behavior in prison but did not provide such a basis
for the remainder of Pierce’s mitigating evidence. The prosecutor’s closing
comments may have exacerbated this problem by impressing upon the jury that
its deliberations should be guided by the special issues alone. The prosecutor’s
comments at voir dire may have also undermined the jury’s ability to give
meaningful consideration and effect under the special issues to the evidence of

                                          22
                                  No. 08-70042

Pierce’s youth. Accordingly, we affirm the district court’s order of resentencing.
Because we affirm on this basis, we do not consider whether Pierce’s claim of
ineffective assistance of counsel at sentencing provides an alternative basis for
resentencing. Accord Beckham v. Wainwright, 

, 265 n.4 (5th Cir.
Unit B Mar. 1981) (declining to consider whether the alleged denials of the right
to confrontation and right to jury trial provided bases for habeas relief and a new
trial because the petitioner’s ineffective assistance claim provided such a basis).
                          IV. THE ATKINS CLAIM
      We granted a COA on the issue of whether Pierce is ineligible for the death
penalty under Atkins v. Virginia, 

, in which the Supreme Court held
that the Eighth Amendment forbids the execution of mentally retarded persons.
The Atkins Court “le[ft] to the State[s] the task of developing appropriate ways
to enforce the constitutional restriction upon their execution of sentences.” 

(alterations and internal quotation marks omitted). In Texas, a finding
of mental retardation requires:       (1) significantly sub-average intellectual
functioning (generally, an IQ of 70 or below); (2) deficits in adaptive functioning;
and (3) onset before age 18. See Ex parte Briseno, 

, 7 (Tex. Crim.
App. 2004). Pierce bore the burden of establishing by a preponderance of the
evidence that he is mentally retarded. 

12; Woods v. Quarterman, 

, 585 & n.3 (5th Cir. 2007). Pierce contends that the district court erred
in concluding that the state habeas court was not unreasonable in determining
that Pierce does not meet the Texas definition of a mentally retarded person.
A.    Background
      We briefly summarize the evidence that the state habeas court considered
as to Pierce’s Atkins claim in order to provide a background for our analysis of
Pierce’s contentions. Dr. George Denkowski submitted an affidavit for the State.
Dr. Denkowski reviewed documents and examined Pierce in prison,
administering, among other tests, the Stanford–Binet Intelligence Scales—Fifth

                                        23
                                  No. 08-70042

Edition (SB-5) and the Adaptive Behavior Assessment System (ABAS). Pierce
attained a full-scale IQ score of 80 on Dr. Denkowski’s administration of the SB-
5. Dr. Denkowski opined that Pierce’s IQ might actually be slightly higher than
this score suggested because Pierce suffered from moderate anxiety and mild
depression, which may have suppressed the score. Pierce’s ABAS results showed
a significant adaptive deficit only in functional academics.
      Three expert witnesses submitted affidavits on Pierce’s behalf. The first
expert, Dr. June Kaufman, examined and evaluated Pierce in connection with
his original state habeas application in 1990. Dr. Kaufman’s affidavit did not
include an IQ score for Pierce, but did opine that he was “functionally mentally
retarded” and displayed adaptive deficits in the form of “understand[ing]
society’s basic value systems and conventions,” which resulted in “extremely
poor social judgment in everyday life situations.” The second expert, Dr. Richard
Garnett, did not examine Pierce but did review his records. Dr. Garnett noted
that Pierce had attained IQ scores ranging from 67 to 81 on various tests
administered during his childhood and young adulthood and observed that
Pierce appeared to perform best in structured settings, a trait common among
the mentally retarded. The third expert, Dr. Susana Rosin, administered the
Wechsler Adult Intelligence Scale III, on which Pierce attained an IQ score of 70.
Dr. Denkowski’s affidavit questioned that score, arguing that the result was
unreliable because Dr. Rosin had administered only a short form of that test.
Dr. Rosin also completed the Vineland Adaptive Behavior Scales using
information from Pierce’s records, reports from the Assistant Warden on death
row, and information provided by Pierce. Dr. Rosin’s Vineland results showed
a significant adaptive deficit only in communication.
      The State habeas trial court considered these affidavits and adopted the
proposed findings of fact and conclusions of law submitted by the State. These
included that the contents of Dr. Denkowski’s affidavit—including his various


                                       24
                                  No. 08-70042

criticisms of Pierce’s experts’ affidavit testimony—were credible. These also
included that because Dr. Garnett was not certified by the Texas Department of
Mental Health and Mental Retardation to make a diagnosis of mental
retardation but was instead a licensed marriage and family counselor, he was
not qualified to make a diagnosis of mental retardation under Texas law. The
TCCA rejected the state habeas trial court’s finding as to Dr. Garnett’s
qualification to diagnose mental retardation, but otherwise adopted the state
habeas trial court’s findings of fact and conclusions of law.
      In support of his claim for federal habeas relief, Pierce sought an
evidentiary hearing in the federal district court as to whether he is mentally
retarded. Pierce urged in the district court, and continues to urge in this court,
that a hearing is warranted because there is “new evidence” that Dr. Denkowski
was discredited by the TCCA in another death penalty case after making several
methodological errors. See Ex parte Plata, No. AP-75820, 

(Tex.
Crim. App. Jan. 16, 2008) (per curiam). Pierce contends that Dr. Denkowski
committed some of those same errors in the present case and also points to
additional purported shortcomings in Dr. Denkowski’s analysis that did not
occur in Plata. Pierce also asserts, for the first time on appeal, that the state
habeas trial court erroneously found that Dr. Garnett was not qualified to
diagnose mental retardation, and that although the TCCA declined to adopt this
finding, other of the findings that the TCCA did adopt were premised upon this
finding.
      The district court declined to hold an evidentiary hearing on the putative
new evidence and concluded that all of the errors that Dr. Denkowski
purportedly committed in Plata either were not committed in Pierce’s case or
would not have affected the state habeas court’s conclusions. Pierce, 

, at **13–15. Pierce asks this court to conclude that the district court
abused its discretion in refusing to hold an evidentiary hearing.          In the

alternative, Pierce asks, for the first time on appeal, that this court stay the case
and hold it in abeyance while the state habeas court (to which he proposes to
repair) considers the “new evidence” as to Dr. Denkowski’s performance in Plata.
B. Atkins Issues Raised in the COA Application
      Pierce’s COA application raised the following five specific issues as bases
for relief under Atkins:
1.    As in Plata, Dr. Denkowski improperly contended that depression and
      anxiety had a suppressive effect on Pierce’s IQ score;

2.    As in Plata, Dr. Denkowski improperly evaluated Pierce’s adaptive deficits
      and overstated the impact of sociocultural factors on these deficits;

3.    Dr. Denkowski improperly criticized the results of IQ tests administered
      to Pierce by other experts as being less reliable because only certain
      subparts were administered;

4.    Dr. Denkowski failed to inform the court of the “Flynn Effect,” which
      might have artificially inflated Pierce’s IQ score on tests administered by
      other experts in 1975 and 1976. Dr. Denkowski also failed to inform the
      court that these same tests may be structured so as to overrepresent IQ;
      and

5.    The state habeas trial court made a clearly erroneous finding of fact that
      one of Pierce’s experts, Dr. Garnett, was not qualified to diagnose mental
      retardation. Although the TCCA declined to adopt this finding of fact, the
      state habeas trial court’s other findings of fact as to Dr. Garnett, which the
      TCCA did adopt, improperly relied on this erroneous finding.
      In granting a COA, we directed Pierce to “provide a record citation to
where each such issue was raised before the state habeas court and federal
district court—or, if the issue was not raised in these forums, to explain why the
issue could not have been raised there.”
C.    Analysis
      For the first two issues on which we granted a COA, Pierce contends that,
as in Plata, Dr. Denkowski improperly testified that depression and anxiety had
a depressive effect on Pierce’s IQ score and improperly evaluated Pierce’s

                                         26
                                       No. 08-70042

adaptive deficits, overstating the impact of sociocultural factors on these deficits.
But the district court addressed both of these arguments. As to Pierce’s IQ
score, the district court observed that in Pierce’s case, unlike in Plata, “Dr.
Denkowski did not have to rely on claims of clinical judgment to achieve an IQ
score that is above the mentally retarded range.” Pierce, 

, at
*13. Pierce attained a full-scale IQ of 80 on Dr. Denkowski’s administration of
the SB-5 before making any adjustments for depression or anxiety. 

Pierce’s adaptive deficits, the district court held that even if Dr. Denkowski’s
evidence were not considered, “the evidence supports a finding that Pierce does
not have significant deficits in adaptive behavior.” 

Pierce’s COA
application and supplemental briefing do not actually challenge the district
court’s conclusions as to these issues. These issues, therefore, do not provide a
basis for Atkins relief.10 See Ortiz v. Quarterman, 

, 501 n.6 (5th Cir.
2007); Hughes v. Johnson, 

, 613 (5th Cir. 1999).
       As to the third and fourth issues on which we granted a COA—that Dr.
Denkowski improperly criticized the reliability of Pierce’s short-form IQ test
scores and failed to explain how the “Flynn Effect” and structural test flaws
would have inflated the results of tests that other specialists administered to
Pierce—Pierce concedes that he never raised these issues before the district
court. Pierce contends that he did not do so because his strategy before the
district court was to argue “that Denkowski’s credibility had been globally
undermined by Plata and that an evidentiary hearing was required to determine
precisely how Denkowski applied similarly flawed methodologies in this case.”



       10
          In any event, to the extent that Dr. Denkowski might have committed these errors
in Pierce’s case, the fact of these errors would not be “new evidence” in light of Plata because
these errors were factual in nature and could have been identified by Pierce’s experts before
Plata was published. Pierce submitted the affidavit testimony of three expert witnesses on
mental retardation in connection with his state habeas application and federal habeas petition.
None of these affidavits cited any errors in Dr. Denkowski’s affidavit.

                                              27
                                        No. 08-70042

Pierce argues that the “gist” of his argument in the district court was that Dr.
Denkowski’s entire opinion was infected with errors, and that he raised these
discrete issues on appeal simply to highlight examples: “These arguments were
intended to highlight significant flaws in Denkowski’s methodologies . . . and to
show that it is simply not possible to carve out the flawed portions of
Denkowski’s report and then make a determination that what remains is
scientifically sound and supports the state court’s decision.”
       Pierce’s argument is not persuasive and does not provide a basis for
granting habeas relief or an evidentiary hearing. First, Pierce admits that he
did not raise these contentions in the district court. “‘[W]e have repeatedly held
that a contention not raised by a habeas petitioner in the district court cannot
be considered for the first time on appeal from that court’s denial of habeas
relief.’” Goodrum v. Quarterman, 

, 259 n.49 (5th Cir. 2008) (quoting
Johnson v. Puckett, 

, 448 (5th Cir. 1991)). Second, contrary to
Pierce’s assertions about his “global” strategy in the district court, Pierce did in
fact argue in the district court that Dr. Denkowski’s affidavit contained a
number of specific errors—but those alleged errors were different than those
that he now urges on appeal. Third, none of Pierce’s own experts raised the
“Flynn Effect” or structural test flaws as reasons for concluding that Pierce’s IQ
was lower than his scores on IQ tests not administered by Dr. Denkowski might
indicate. Finally, neither the accuracy of short-form test scores, nor the “Flynn
Effect,” nor alleged structural test flaws were at issue in Plata. In short, Pierce’s
argument that Dr. Denkowski’s work in Plata provides “new evidence” that Dr.
Denkowski performed deficiently has no merit and does not provide a basis for
habeas relief or an evidentiary hearing.11 Because Pierce’s contentions as to

       11
          Pierce seems to suggest that errors in an expert witness’s work in another case,
without a showing that those errors occurred in or may have affected the outcome of the
petitioner’s case, can provide a proper basis for habeas relief or an evidentiary hearing. Pierce
cites no authority for this proposition, and we have located none. In evaluating Pierce’s

                                               28
                                      No. 08-70042

“new evidence” lack merit, we also deny Pierce’s request, raised for the first time
on appeal, to stay the case and hold it in abeyance while the state habeas court
considers the “new evidence” as to Dr. Denkowski’s performance in Plata.
       As to the fifth issue on which we granted a COA—whether the state
habeas court’s finding that Dr. Garnett was not qualified to diagnose mental
retardation, which the TCCA rejected, improperly affected other findings of fact
about Dr. Garnett that the TCCA adopted—Pierce again admits that he did not
raise this issue before the district court. It therefore does not provide a basis for
relief. See 

n.49; 

. In any
event, the TCCA’s order reveals no evidence of any such taint. The TCCA
adopted the following factual findings: Dr. Garnett did not examine Pierce but
merely reviewed his records; Dr. Garnett is not licensed as a psychologist in the
state of Texas but instead is a licensed marriage and family counselor; in other
cases, Dr. Garnett has been found to be biased or inexperienced; and based on
other evidence in the record as to Pierce’s mental faculties, Dr. Garnett’s
diagnosis of mental retardation was “unpersuasive.” None of these findings
relies on the trial court’s erroneous finding, rejected by the TCCA, that Dr.
Garnett was unqualified to diagnose an individual as mentally retarded. There
is no basis in the record to conclude that the TCCA’s findings were in any way
dependent on the finding of fact that the TCCA rejected.
       None of the issues raised in Pierce’s habeas application provides a basis
for habeas relief or an evidentiary hearing. Accordingly, we affirm the district
court’s denial of Atkins relief.
D.     The Dissent’s Argument for an Evidentiary Hearing


application for habeas relief, the district court’s task was to determine whether the state
habeas court’s determination of the facts was reasonable and whether the “new evidence” of
Dr. Denkowski’s performance in Plata called that determination into question. The district
court concluded that the errors in Plata that Pierce contended Dr. Denkowski also made in his
own case either did not occur or would not have affected the result.

                                             29
                                       No. 08-70042

       The dissent argues that Pierce is entitled to an evidentiary hearing in the
federal district court on his Atkins claim because the state habeas court did not
hold a live evidentiary hearing to determine whether Pierce was mentally
retarded. The dissent urges this court to conclude that, as a matter of clearly
established Supreme Court law, a live evidentiary hearing is “guaranteed to a
prisoner who has made a plausible showing of mental retardation.”
       The most critical obstacle to the relief the dissent proposes is that Pierce
never, in either his pleadings or voluminous briefing, cited the lack of a live
evidentiary hearing in the state habeas court as a basis for obtaining an
evidentiary hearing in the federal district court.12 Throughout his federal
habeas proceedings, Pierce’s request for an evidentiary hearing has been
premised solely on the propositions—which this entire panel has rejected—that
Plata provided “new evidence” that Dr. Denkowski’s affidavit testimony to the
state habeas court was unreliable and that the TCCA may have adopted
erroneous findings of fact regarding Dr. Garnett. Under our precedents, because
Pierce did not raise the lack of an evidentiary hearing in the state court as a
basis for relief in the district court or even in his pleadings and briefing to this
court, we cannot consider it here. See 

n.49; 

.
                                  V. CONCLUSION
       We AFFIRM the district court’s grant of habeas relief based on the Penry
violations at Pierce’s sentencing, and accordingly AFFIRM the district court’s
resentencing order. Because we affirm resentencing on this basis, we do not
address whether Pierce’s ineffective assistance of counsel claim provides an



       12
          Pierce did not make an effort to develop this argument even when the dissent to our
denial of a COA specifically invited him to do so—rather, in his supplemental briefing, Pierce
stated only that he “would add the concerns discussed by Justice Dennis in his concurring and
dissenting opinion in this case as additional reasons why a hearing is required in this case.”

additional basis for resentencing. We AFFIRM the district court’s denial of
habeas relief and an evidentiary hearing on Pierce’s Atkins claim.

DENNIS, Circuit Judge, concurring in part and dissenting in part:
       I respectfully dissent from the majority’s reasons and conclusion in
rejecting Pierce’s Atkins claim, because the procedure the Texas courts used to
determine whether Pierce is mentally retarded did not comply with the
requirements of constitutional due process. In all other respects consistent with
this view, I concur in the majority opinion.
                                               I.
       Pierce was found not to be mentally retarded by a state habeas court
judge on the basis of an affidavit by the state’s expert, without a live adversarial
evidentiary hearing, without an opportunity to testify or call witnesses, and
without an opportunity to confront and cross-examine the witness against him.
In the state habeas proceedings, Pierce presented the affidavits of three mental
retardation experts, Dr. June Kaufman, Dr. Richard Garnett, and Dr. Susana
Rosin, who each set forth his or her findings, evaluation and opinion that Pierce
is mentally retarded.1 The state presented the affidavit of its expert, Dr. George

       1
         Dr. Kaufman, a clinical psychologist, evaluated Pierce in 1990. She administered the
Wechsler Adult Intelligence Scale-Revised, the result of which she considered “without
question valid.” Dr. Kaufman also noted that Pierce exhibited classic traits of the mentally
retarded and pointed to Pierce’s adaptive behavioral issues, observing that he did not think
through the consequences of his actions, had gross deficiencies comprehending society’s basic
value systems and conventions and exhibited extremely poor social judgment in everyday life
situations. Against this background and his earlier IQ scores of 74 in 1972 and 1974 and 67
in 1975, Dr. Kaufman concluded that Pierce was mentally retarded at the time of the crime
in 1977.
        Dr. Garnett submitted an affidavit in support of Pierce’s successive state habeas
petition in 2002. Dr. Garnett also opined that Pierce was mentally retarded. He noted that
Pierce scored below 75 on seven IQ tests over a period of several years, and that a test score
of 81 on the Wechsler Adult Intelligence Scale in 1976 was an outlier and may have had to do
with hints from the administrator or the test-retest factor. Further, Dr. Garnett also noted
that Pierce had significant adaptive deficits. He pointed out that it was common for a mentally
retarded person to respond well to structured settings, such as a prison, as is the case with
Pierce, only to revert back to unacceptable or illegal behavior as soon as he is outside of that
environment.
        Dr. Rosin, a clinical psychologist, evaluated Pierce in support of his state habeas
application in 2002. She noted that Pierce’s school records showed a consistent pattern of
underachievement and observed that Pierce obtained full scale IQ scores of 69 at age nine and
74 at age twelve, both on the Otis-Lennon Test of Mental Ability, and two scores of 67 and 75
on tests administered in 1975. Dr. Rosin administered the Wechsler Adult Intelligence
Scale-III, on which Pierce scored an IQ of 70. Dr. Rosin further noted that Pierce had
                                       No. 08-70042

Denkowski, which set forth his evaluation and opinion that Pierce is not
mentally retarded. Dr. Denkowski’s affidavit also contained his reasons for
discounting or disagreeing with the contrary opinions of Pierce’s experts.2 Pierce
requested a contradictory evidentiary hearing. But the state habeas court
denied Pierce’s motion and did not seek any further input from Pierce’s experts.
Rather, the state court found that Dr. Denkowski presented a “credible affidavit”
and, on the basis of that affidavit, decided that Pierce is not mentally retarded.3
Accordingly, the state habeas trial court held that Pierce is not exempt from the




significant deficits in conceptual, social and practical skills, pointing to his long history of
problems socializing with others, exercising sound judgment, resisting peer pressure, and
learning from past experiences. According to Dr. Rosin, his IQ score and his adaptive deficits
placed him in the mildly mentally retarded range.
       2
         Dr. Denkowski reviewed Pierce’s files and evaluated him on death row. He
administered the Stanford-Binet Intelligence Scales-Fifth Edition, on which he said Pierce
achieved a score of 80. Dr. Denkowski opined that, adjusted for moderate anxiety and mild
depression, his score was actually in the 80 to 84 range. Further, Dr. Denkowski opined that,
apart from his low academic skills, Pierce did not have significant deficits in adaptive
functioning. Dr. Denkowski’s affidavit otherwise focused on criticizing the opinions of Pierce’s
three experts–shielded from any form of response or cross examination.
       3
         The state habeas court completely ignored that the expert witnesses examined Pierce
at wide intervals (in one instance over a decade apart) and under differing circumstances, with
some having analyzed Pierce and made findings prior to the Supreme Court’s decision in
Atkins; a wide variety of tests were administered involving varying parameters and substantial
nuance and complexity; and the mental health experts sharply disagreed on whether Pierce
is mentally retarded and submitted diametrically opposed affidavits. Additionally, the
qualifications and integrity of Dr. Denkowski, whose affidavit was the pivotal and exclusive
basis for the state trial habeas court’s finding that Pierce was not mentally retarded, are now
under close scrutiny and his methods have been recognized to be unreliable by this court, the
Texas state courts, and the state licensing authorities. See Hall v. Quarterman, 

,

death penalty. On appeal, the TCCA adopted the state habeas trial court’s
findings and conclusions.4
       The federal district habeas court refused to grant Pierce an evidentiary
hearing on his Atkins claim, found that the state courts’ rejection of his Atkins
claim was not unreasonable under AEDPA, and therefore rejected his petition
for federal habeas relief. Pierce v. Quarterman, No. H-07-1561, 

, at **13-15 (S.D. Tex. Sept. 26, 2008). In doing so, the district court
failed to enforce Pierce’s clearly established constitutional right to procedural
due process.
                                             II.
       Construing and applying the Eighth Amendment in the light of our
“evolving standards of decency,” the Supreme Court in Atkins v. Virginia, 

, 321 (2002), held that the Constitution “‘places a substantive restriction
on the State’s power to take the life’ of a mentally retarded offender.” 

v. Wainwright, 

, 405 (1986)). In Schriro v. Smith, the
Court observed that Atkins stated in clear terms that “‘we leave to the State[s]
the task of developing appropriate ways to enforce the constitutional restriction
upon [their] execution of sentences,’” 

, 7 (2005) (alterations in original)
(quoting 

), but also stated that “those measures might,
in their application, be subject to constitutional challenge,” 

Atkins a person has a substantive right not to be executed if he is mentally
retarded, and once he makes a prima facie showing that he is mentally retarded,




       4
        The only state habeas trial court finding not adopted by the TCCA was its clearly
erroneous exclusion of Dr. Garnett’s affidavit on the basis that he was not licensed in Texas
and thus ineligible to opine on mental retardation in civil commitments under the Persons with
Mental Retardation Act, Tex. Health & Safety Code § 591.003(16).

he is entitled to an adjudication meeting constitutional standards to determine
his condition.5
       “The Fourteenth Amendment’s Due Process Clause protects persons
against deprivations of life, liberty, or property; and those who seek to invoke its
procedural protection must establish that one of these interests is at stake.”
Wilkinson v. Austin, 

, 221 (2005). “A liberty interest may arise from
the Constitution itself, by reason of guarantees implicit in the word ‘liberty,’ or
it may arise from an expectation or interest created by state laws or policies.”

v. Jones, 

, 493-494 (1980) (liberty interest in
avoiding involuntary psychiatric treatment and transfer to mental institution)
& Wolff v. McDonnell, 

, 556-558 (1974) (liberty interest in avoiding
withdrawal of state-created system of good-time credits)).
       In Vitek, the Court held that, “[b]ecause prisoners facing involuntary
transfer to a mental hospital are threatened with immediate deprivation of
liberty interests and because of the inherent risk of a mistaken transfer,” due
process requires procedures similar to those required in parole revocation
proceedings. 

(citing Morrissey v. Brewer, 

(1972)).
According to Vitek, the minimum procedures before transferring a prisoner to a
mental hospital include the following: (1) “Written notice to the prisoner that a
transfer to a mental hospital is being considered”; (2) “A hearing, sufficiently
after the notice to permit the prisoner to prepare, at which disclosure to the
prisoner is made of the evidence being relied upon for the transfer and at which
an opportunity to be heard in person and to present documentary evidence is
given”; (3) “An opportunity at the hearing to present testimony of witnesses by
the defense and to confront and cross-examine witnesses called by the state”; (4)


       5
        See Panetti v. Quarterman, 

, 934-35 (2007) (“Under Ford, once a prisoner
makes the requisite preliminary showing that his current mental state would bar his
execution, the Eighth Amendment, applicable to the States under the Due Process Clause of
the Fourteenth Amendment, entitles him to an adjudication to determine his condition.”).

“An independent decisionmaker”; (5) “A written statement by the factfinder as
to the evidence relied on and the reasons for transferring the inmate”; (6) “[In
some instances] [a]vailability of legal counsel, furnished by the state, if the
inmate is financially unable to furnish his own”; and (7) “Effective and timely
notice of all the foregoing rights.” 

see also 

(listing elements of due process for parole revocations). If these elements of
due process are constitutionally required before a state may revoke a former
prisoner’s parole (Morrissey) or involuntarily hospitalize and treat a prisoner for
mental illness (Vitek), certainly they are guaranteed to a prisoner who has made
a plausible showing of mental retardation before he may be declared mentally
fit and eligible for execution.
       The Court’s decisions, especially Vitek, Morrissey, and Wolff, clearly
indicate that Pierce, who made a prima facie showing that he is mentally
retarded, is entitled to have his condition adjudicated in a contradictory
evidentiary hearing in which he has an opportunity to present testimony of
witnesses and to confront and cross-examine witnesses called by the state. The
state courts plainly failed to provide Pierce with these constitutional procedures
required by due process. Because Pierce’s liberty interest at issue here arises
directly from the Constitution itself, and not from an expectation or interest
created by state laws or policies, his case invokes the full due process protections
established by Vitek and Morrissey and does not call for the additional step of
applying the framework established in Mathews v. Eldridge, 

(1976).6 Moreover, application of Mathews here serves only to confirm that all
of the due process essentials set forth in Morrissey are required in this case. The


       6
         Under the Mathews balancing test, we weigh “[f]irst, the private interest that will be
affected by the official action; second, the risk of an erroneous deprivation of such interest
through the procedures used, and the probable value, if any, of additional or substitute
procedural safeguards; and finally, the Government’s interest, including the function involved
and the fiscal and administrative burdens that the additional or substitute procedural
requirement would entail.”

private interest that will be affected by the official action here, Pierce’s life, is,
of course, maximal. The risk of an erroneous deprivation of such an interest
through lesser procedures than those established by Morrissey is intolerably
great, and the value of requiring additional procedural safeguards is
extraordinarily high. Consequently, the government’s interest in avoiding the
cost of additional process, including the function involved and the fiscal and
administrative burdens that the additional or substitute procedural
requirements would entail, is relatively small and does not outweigh the other
considerations involved or justify a lesser level of process.7
       Under AEDPA, a federal court may grant habeas relief only if the state
court’s adjudication of the claim on the merits “resulted in a decision that was
contrary to, or involved an unreasonable application of, clearly established
Federal law, as determinated by the Supreme Court of the United States,” or
“resulted in a decision that was based on an unreasonable determination of the
facts in light of the evidence presented in the State court proceeding.” 28 U.S.C.
§ 2254(d). “When a state court’s adjudication of a claim is dependent on an
antecedent unreasonable application of federal law, the requirement set forth in
28 U.S.C. § 2254(d)(1) is satisfied. A federal court must then resolve the claim
without the deference AEDPA otherwise requires.” 

(citing Wiggins v. Smith, 

, 527-29, 534 (2003)). “Here, due to the

         It bears emphasis, moreover, that Pierce is one of the few Texas death row inmates
who has not been afforded such a full due process hearing in a post-Atkins case. Starting with
Ex parte Briseno, 

(Tex. Crim. App. 2004), in which the Texas Court of Criminal
Appeals implemented the Supreme Court’s pronouncements in Atkins, the prisoner was
granted a live hearing on remand in state trial court to determine whether he was mentally
retarded. As Judge Higginbotham observed, “Texas courts quickly found their footing
post-Atkins. . . . Briseno was also convicted before Atkins but . . . received a five-day
evidentiary hearing on his post-Atkins habeas claim of mental retardation.” 

(Higginbotham, J., concurring in part and dissenting in part) (citing 

). Such live hearings have become the norm in Atkins cases in the Texas state courts. See
Sarah Gail Tuthill, Comment, The Texas-Size Struggle to Implement Atkins v. Virginia, 14 Tex.

state court’s unreasonable application of [Atkins, Vitek, Morrissey, and Wolff,]
the factfinding procedures upon which the court relied were ‘not adequate for
reaching reasonably correct results’ or, at a minimum, resulted in a process that

      For these reasons, in my view, the judgment of the federal district court
deferring to the state courts’ rulings on Pierce’s mental condition should be
vacated and the case should be remanded in part to the district court with
directions to consider Pierce’s Atkins claim on the merits in an adversarial
evidentiary hearing in accordance with the foregoing due process principles and
without deferring to the state courts’ findings.
