    HARRY FRANKLIN PHILLIPS,
    Appellant,
    vs.
    STATE OF FLORIDA,
    Appellee.
    May 21, 2020
    PER CURIAM.
    Harry Franklin Phillips, a prisoner under sentence of death, appeals the
    circuit court’s order summarily denying his successive motion for postconviction
    relief, which was filed under Florida Rule of Criminal Procedure 3.851. We have
    jurisdiction. See art. V, § 3(b)(1), Fla. Const.
    Phillips murdered Bjorn Thomas Svenson in 1982, and his conviction and
    death sentence for that crime became final in 1998. A postconviction court in 2006
    fully adjudicated and denied Phillips’s claim that he is intellectually disabled and,
    under the rule of Atkins v. Virginia, 
    536 U.S. 304
    (2002), constitutionally ineligible
    for the death penalty. We affirmed the denial of Phillips’s intellectual disability
    claim in 2008. Phillips now seeks yet another determination of his intellectual
    disability, relying in part on this Court’s decision in Walls v. State, 
    213 So. 3d 340
    (Fla. 2016), in which we held that the United States Supreme Court’s decision in
    Hall v. Florida, 
    572 U.S. 701
    (2014), is retroactive to cases where there has
    already been a finding that the defendant is not intellectually disabled.
    For the reasons we explain, we affirm the circuit court’s denial of relief. We
    also recede from our prior decision in Walls.
    I. BACKGROUND
    The facts of the case were summarized on direct appeal as follows:
    In the evening of August 31, 1982, witnesses heard several
    rounds of gunfire in the vicinity of the Parole and Probation building
    in Miami. An investigation revealed the body of Bjorn Thomas
    Svenson, a parole supervisor, in the parole building parking lot.
    Svenson was the victim of multiple gunshot wounds. There
    apparently were no eyewitnesses to the homicide.
    As parole supervisor, the victim had responsibility over several
    probation officers in charge of appellant’s parole. The record
    indicates that for approximately two years prior to the murder, the
    victim and appellant had repeated encounters regarding appellant’s
    unauthorized contact with a probation officer. On each occasion, the
    victim advised appellant to stay away from his employees and the
    parole building unless making an authorized visit. After one incident,
    based on testimony of the victim and two of his probation officers,
    appellant’s parole was revoked and he was returned to prison for
    approximately twenty months.
    On August 24, 1982, several rounds of gunfire were shot
    through the front window of a home occupied by the two probation
    officers who had testified against appellant. Neither was injured in
    the incident, for which appellant was subsequently charged.
    Following the victim’s murder, appellant was incarcerated for
    parole violations. Testimony of several inmates indicated that
    -2-
    appellant told them he had killed a parole officer. Appellant was
    thereafter indicted for first-degree murder.
    Phillips v. State, 
    476 So. 2d 194
    , 195-96 (Fla. 1985). Phillips was convicted of the
    first-degree murder of Svenson and sentenced to death.
    Id. at 197.
    His conviction
    and sentence were affirmed on direct appeal,
    id., but on
    collateral review, this
    Court reversed the death sentence and remanded for a new penalty phase based on
    a finding that counsel was ineffective in the penalty phase, Phillips v. State, 
    608 So. 2d 778
    (Fla. 1992). After a new penalty phase in 1994, the jury returned a
    recommendation of death by a vote of seven to five, and Phillips was again
    sentenced to death, which was affirmed on appeal. Phillips v. State, 
    705 So. 2d 1320
    , 1321, 1323 (Fla. 1997), cert. denied, 
    525 U.S. 880
    (1998). We later
    affirmed the denial of Phillips’s initial motion for postconviction relief after
    resentencing and denied his petition for a writ of habeas corpus. Phillips v. State,
    
    894 So. 2d 28
    , 31 (Fla. 2004). And we have affirmed the denial of his prior
    successive motions for postconviction relief. Phillips v. State, 
    234 So. 3d 547
    , 548
    (Fla.) (affirming denial of successive motion for postconviction relief based on
    Hurst v. Florida, 
    136 S. Ct. 616
    (2016), and Hurst v. State, 
    202 So. 3d 40
    (Fla.
    2016)), cert. denied, 
    139 S. Ct. 187
    (2018); Phillips v. State, 
    91 So. 3d 783
    (Fla.
    2012) (affirming denial of successive motion for postconviction relief based on the
    claim that Phillips’s sentence violates the Sixth and Eighth Amendments under
    Porter v. McCollum, 
    558 U.S. 30
    (2009)); Phillips v. State, 
    996 So. 2d 859
    (Fla.
    -3-
    2008) (affirming denial of successive motion for postconviction relief and denial of
    motion to interview jurors); Phillips v. State, 
    984 So. 2d 503
    (Fla. 2008) (affirming
    finding that Phillips is not intellectually disabled).
    During Phillips’s initial postconviction proceedings after resentencing,
    Phillips filed a “Notice of Supplemental Authority and Motion for Permission to
    Submit Supplemental Briefing” related to the United States Supreme Court’s
    decisions in Ring v. Arizona, 
    536 U.S. 584
    (2002), and Atkins, and this Court
    permitted supplemental briefing on the intellectual disability issues under Atkins.
    
    Phillips, 894 So. 2d at 34
    . We affirmed the denial of postconviction relief and
    denied the habeas petition, but regarding his claim of intellectual disability, we
    noted that “Phillips [was] free to file a motion under rule 3.203” but expressed “no
    opinion regarding the merits of such a claim.”
    Id. at 40.
    We later relinquished
    jurisdiction for a determination of intellectual disability pursuant to Florida Rule of
    Criminal Procedure 3.203. 
    Phillips, 984 So. 2d at 506
    .
    At an evidentiary hearing on Phillips’s intellectual disability claim in 2006,
    the circuit court permitted Phillips to present evidence regarding all three prongs of
    the intellectual disability standard and concluded that Phillips failed to prove by
    clear and convincing evidence that he met any of the three prongs of the statutory
    intellectual disability standard (intellectual functioning, adaptive behavior, and
    onset before age eighteen) and therefore was not intellectually disabled.
    Id. at 509.
    -4-
    In 2008, this Court upheld the circuit court’s findings that Phillips failed to
    establish that he met any of the three prongs and affirmed the denial of relief based
    on his claim of intellectual disability.
    Id. at 513.
    Phillips filed the instant successive motion for postconviction relief in 2018
    seeking a new determination of his claim that he is ineligible for the death penalty
    due to intellectual disability in light of the decisions in Hall, Walls, and Moore v.
    Texas, 
    137 S. Ct. 1039
    (2017). Phillips contended that the prior denial of his
    intellectual disability claim must be reheard and determined under new
    constitutional law that, according to Phillips, requires a court to holistically
    consider all three prongs of the intellectual disability standard.
    At a case management conference held in the circuit court on Phillips’s
    motion, Phillips argued that in light of Hall and Walls, and a new evaluation report
    prepared by Dr. Denis Keyes, who had testified at the 2006 hearing, he is entitled
    to a new evidentiary hearing. Alternatively, Phillips requested that the circuit court
    reevaluate the evidence presented at the 2006 hearing along with Dr. Keyes’s new
    report, although Phillips conceded that there was no new evidence of intellectual
    disability in this case and that Dr. Keyes did not change his opinion in his updated
    report. The circuit court abruptly decided during the case management conference
    -5-
    that it would review de novo the entire record from the 2006 hearing 1 and Dr.
    Keyes’s new report before making any decision on Phillips’s motion.
    On June 14, 2018, the circuit court entered an order denying an evidentiary
    hearing and denying relief. But in its 2018 order, the circuit court also made new
    findings regarding the evidence presented at the 2006 evidentiary hearing. First, it
    concluded that because Hall requires that courts take into account the standard
    error of measurement (SEM), which is “plus or minus five points” and “[a]n IQ of
    up to 75 would meet the definition of [intellectual disability],” Phillips “has clearly
    proven the first prong by clear and convincing evidence,” because the IQ scores
    presented in 2006 were 70, 74, and 75. 2 The circuit court also made a new finding
    that Phillips met the third prong—onset before age eighteen. 3 Nonetheless, the
    1. Because it is not germane to our analysis or conclusion today, we make
    no comment on the propriety of the circuit court’s decision to conduct a de novo
    review of the record of the 2006 evidentiary hearing or of the new credibility
    determinations it made regarding witnesses who testified in 2006 based on the cold
    record.
    2. In reaching this conclusion, however, the 2018 circuit court ignored the
    fact that the 2006 circuit court found that because neither of the defense experts
    performed a complete evaluation that tested for malingering, they were not
    credible on this prong.
    3. But in doing so, the 2018 circuit court either ignored or rejected—without
    explanation—the finding made by the 2006 circuit court (and affirmed by this
    Court in 2008) that Phillips failed to establish that he met this prong, and simply
    concluded instead “that Dr. Keyes[’s] testimony from the 2006 hearing is credible
    and sufficient to prove onset before 18.”
    -6-
    2018 circuit court ultimately declined to find that Phillips is intellectually disabled
    based on its agreement with the 2006 circuit court’s finding (and this Court’s 2008
    opinion affirming that finding) that Phillips failed to establish that he met the
    second prong of the intellectual disability standard—concurrent deficits in adaptive
    behavior. Phillips now appeals that decision.
    II. ANALYSIS
    First, we review the recent history of intellectual disability as a bar to
    execution. Then we discuss the clear error in this Court’s decision in Walls and
    why Hall does not entitle Phillips to relief. Finally, we consider and reject
    Phillips’s claim that he is entitled to relief based on Moore.
    A. Intellectual Disability as a Bar to Execution
    In 2002, the United States Supreme Court held in Atkins that the Eighth and
    Fourteenth Amendments to the United States Constitution forbid the execution of
    persons with intellectual disability. 
    Atkins, 536 U.S. at 321
    . The Court observed
    that “clinical definitions of [intellectual disability] require not only subaverage
    intellectual functioning, but also significant limitations in adaptive skills such as
    communication, self-care, and self-direction that became manifest before age 18.”
    Id. at 318.
    The Atkins Court further noted that an IQ between 70 and 75 or lower
    “is typically considered the cutoff IQ score for the intellectual function prong of
    the [intellectual disability] definition,”
    id. at 309
    n.5, but it did not define
    -7-
    subaverage intellectual functioning as having an IQ of 75 or below or mandate that
    courts take the SEM into account or permit defendants who present a score of 75 or
    below to present additional evidence of intellectual disability. Instead, the Court
    explicitly granted states discretion to determine how to comply with its prohibition
    on execution of the intellectually disabled.
    Id. at 317
    (“As was our approach in
    Ford v. Wainwright, 
    477 U.S. 399
    (1986), with regard to insanity, ‘we leave to the
    State[s] the task of developing appropriate ways to enforce the constitutional
    restriction upon [their] execution of sentences.’ ” (alterations in original)).
    Under Florida law, “ ‘intellectual disability’ means significantly subaverage
    general intellectual functioning existing concurrently with deficits in adaptive
    behavior and manifested during the period from conception to age 18.”
    § 921.137(1), Fla. Stat. (2017). “Significantly subaverage general intellectual
    functioning” is defined as “performance that is two or more standard deviations
    from the mean score on a standardized intelligence test specified in the rules of the
    Agency for Persons with Disabilities.”
    Id. “Adaptive behavior”
    “means the
    effectiveness or degree with which an individual meets the standards of personal
    independence and social responsibility expected of his or her age, cultural group,
    and community.”
    Id. Thus, to
    establish intellectual disability as a bar to
    execution, a defendant must demonstrate (1) significantly subaverage general
    -8-
    intellectual functioning; (2) concurrent deficits in adaptive behavior; and (3)
    manifestation of the condition before age eighteen.
    Until Hall, Florida law required that a defendant have an IQ of 70 or below
    in order to meet the first prong of the intellectual disability standard—significantly
    subaverage intellectual functioning. See Cherry v. State, 
    959 So. 2d 702
    , 712-13
    (Fla. 2007) (“One standard deviation on the WAIS-III, the IQ test administered in
    the instant case, is fifteen points, so two standard deviations away from the mean
    of 100 is an IQ score of 70. As pointed out by the circuit court, the statute does not
    use the word approximate, nor does it reference the SEM. Thus, the language of
    the statute and the corresponding rule are clear.”), abrogated by Hall, 
    572 U.S. 701
    . Thus, a defendant was required to present an IQ score of 70 or below in order
    to establish the first prong of the intellectual disability standard. Failure to present
    the requisite IQ score precluded a finding of intellectual disability.
    In Hall, the Supreme Court held that Florida’s “rigid rule” interpreting
    section 921.137(1) as establishing a strict IQ test score cutoff of 70 or less in order
    to present additional evidence of intellectual disability “creates an unacceptable
    risk that persons with intellectual disability will be executed, and thus is
    
    unconstitutional.” 572 U.S. at 704
    . The Court further held that when assessing the
    subaverage intellectual functioning prong of the intellectual disability standard,
    courts must take into account the standard error of measurement of IQ tests, which
    -9-
    is five points.
    Id. at 723.
    And “when a defendant’s IQ test score falls within the
    test’s acknowledged and inherent margin of error [±5], the defendant must be able
    to present additional evidence of intellectual disability, including testimony
    regarding adaptive deficits.”
    Id. In Walls,
    we considered whether, under the standards set out in Witt v. State,
    
    387 So. 2d 922
    (Fla. 1980), Hall warranted retroactive application to cases on
    collateral review. 
    Walls, 213 So. 3d at 346
    . Under Witt, a change in the law “only
    appl[ies] retroactively if the change ‘(a) emanates from this Court or the United
    States Supreme Court, (b) is constitutional in nature, and (c) constitutes a
    development of fundamental significance.’ ”
    Id. (quoting Witt,
    387 So. 2d 
    at 931).
    We acknowledged that “[i]t is without question that the Hall decision emanates
    from the United States Supreme Court and is constitutional in nature.”
    Id. Regarding the
    third prong of the Witt analysis, a decision is of fundamental
    significance when it either (1) places beyond the authority of the state the power to
    regulate certain conduct or to impose certain penalties or (2) when the rule is of
    sufficient magnitude to necessitate retroactive application under the retroactivity
    test of Stovall v. Denno, 
    388 U.S. 293
    , 297 (1967), and Linkletter v. Walker, 
    381 U.S. 618
    , 636 (1965). See id.; Hernandez v. State, 
    124 So. 3d 757
    , 764 (Fla.
    2012); 
    Witt, 387 So. 2d at 929
    . In concluding that Hall met the third prong of the
    Witt analysis, we declared “that Hall warrants retroactive application as a
    - 10 -
    development of fundamental significance that places beyond the State of Florida
    the power to impose a certain sentence—the sentence of death for individuals
    within a broader range of IQ scores than before.” 
    Walls, 213 So. 3d at 346
    . Based
    on this declaration, we determined that Hall warranted retroactive application.
    Upon further consideration, we have determined that this Court clearly erred in
    reaching that conclusion and we now recede from our decision in Walls.
    B. The Error in the Analysis in Walls
    Because it remains clear that Hall establishes a new rule of law that
    emanates from the United States Supreme Court and is constitutional in nature, it
    satisfies the first two prongs of Witt. 
    Witt, 387 So. 2d at 931
    . Thus, the question of
    Hall’s retroactivity still turns on the third prong of Witt: whether the new rule
    constitutes a “development of fundamental significance.”
    Id. In Walls,
    this Court determined that the Hall decision met the third prong of
    the Witt analysis by “plac[ing] beyond the authority of the state the power to
    regulate certain conduct or impose certain penalties,” because it “removes from the
    state’s authority to impose death sentences more than just those cases in which the
    defendant has an IQ score of 70 or below” and is therefore of fundamental
    significance. 
    Walls, 213 So. 3d at 346
    . We now conclude that this Court erred in
    making that determination.
    - 11 -
    In discussing developments of fundamental significance that fall within the
    category of changes of law that place beyond the authority of the state the power to
    regulate certain conduct or impose certain penalties, this Court in Witt cited as an
    example of a decision falling within that category Coker v. Georgia, 
    433 U.S. 584
    (1977), which held that the Eight Amendment categorically prohibits the
    imposition of the death penalty for the crime of rape of an adult woman as cruel
    and unusual punishment. 
    Witt, 387 So. 2d at 929
    . But contrary to the reasoning of
    the majority in Walls, “Hall places no categorical limitation on the authority of the
    state to impose a sentence of death.” 
    Walls, 213 So. 3d at 350
    (Canady, J.,
    dissenting). The example of Coker is totally inapposite.
    In Hall, the Supreme Court recounted its decisions holding that particular
    punishments are prohibited by the Eighth Amendment “as a categorical matter,”
    such as the denaturalization of natural-born citizens as a punishment, 
    Hall, 572 U.S. at 708
    (citing Trop v. Dulles, 
    356 U.S. 86
    , 101 (1958) (plurality opinion)), the
    imposition of the death penalty for crimes committed by juveniles,
    id. (citing Roper
    v. Simmons, 
    543 U.S. 551
    , 572 (2005)), “[a]nd, as relevant for [Hall],” the
    imposition of the death penalty on persons who are intellectually disabled, id.
    (citing 
    Atkins, 536 U.S. at 321
    ). The Court then unambiguously set out the issue it
    was to address: “The question this case presents is how intellectual disability must
    be defined in order to implement . . . the holding of Atkins.”
    Id. at 709
    (emphasis
    - 12 -
    added). And the holding of Hall was limited to a determination that it is
    unconstitutional for courts to refuse to allow capital defendants whose IQ scores
    are above 70 but within the test’s standard error of measurement to present
    evidence of their asserted adaptive deficits. 
    Hall, 572 U.S. at 723
    . Thus, Hall
    merely “created a procedural requirement that those with IQ test scores within the
    test’s standard of error would have the opportunity to otherwise show intellectual
    disability.” In re Henry, 
    757 F.3d 1151
    , 1161 (11th Cir. 2014).4
    The categorical prohibition on executing the intellectually disabled was not
    expanded by Hall. See 
    Walls, 213 So. 3d at 350
    (Canady, J., dissenting) (“Hall . . .
    does not preclude death sentences for individuals whose scores fall within the
    SEM.”). The issue addressed in Hall was not whether the State is categorically
    prohibited from executing those intellectually disabled defendants with IQs above
    70, but within the SEM. Intellectually disabled persons with IQ scores above 70
    are not a distinct class from intellectually disabled persons with IQ scores of 70 or
    below; all are members of the same class protected by Atkins. In re Hill, 
    777 F.3d 1214
    , 1223 (11th Cir. 2015) (“Hall merely provides new procedures for ensuring
    that States do not execute members of an already protected group.”); Henry, 757
    4. The new rule announced in Hall is a procedural rule because it
    “regulate[s] only the manner of determining the defendant’s culpability.” Schriro
    v. Summerlin, 
    542 U.S. 348
    , 353 (2004) (“[R]ules that regulate only the manner of
    determining the defendant’s culpability are procedural.”).
    - 13 -
    F.3d at 1161 (“The Supreme Court made clear in Hall that the class affected by the
    new rule—those with an intellectual disability—is identical to the class protected
    by Atkins. . . . Hall did not expand this class; instead, the Supreme Court limited
    the states’ power to define the class . . . .”); Elmore v. Shoop, No. 1:07-CV-776,
    
    2019 WL 5287912
    , at *4 (S.D. Ohio Oct. 18, 2019) (“[The class of people which is
    addressed in Hall] is the same class of people that Atkins found ineligible for the
    death penalty because that is the definition of mental retardation/intellectual
    disability the Court used in Atkins. What Hall did was to preclude the State of
    Florida from using an IQ score of 70 as an automatic disqualification for proving
    that a person is in the class of people [who], on account of their intellectual
    disability, may not be executed if they commit murder.”).
    The conclusion “that Hall warrants retroactive application as a development
    of fundamental significance that places beyond the State of Florida the power to
    impose a certain sentence” because it may prohibit execution of intellectually
    disabled persons “within a broader range of IQ scores than before,” Walls, 
    213 So. 3d
    at 346, is therefore incorrect. Hall does not place beyond the authority of the
    State the power to regulate certain conduct or impose certain penalties; Hall
    merely more precisely defined the procedure that is to be followed in certain cases
    to determine whether a person facing the death penalty is intellectually disabled.
    Hall is merely an application of Atkins. Kilgore v. Sec’y, Florida Dept. of Corr.,
    - 14 -
    
    805 F.3d 1301
    , 1314 (11th Cir. 2015) (“[Hall] merely provides new procedures for
    ensuring that states follow the rule enunciated in Atkins.”). Hall’s limited
    procedural rule does nothing more than provide certain defendants—those with IQ
    scores within the test’s margin of error—with the opportunity to present additional
    evidence of intellectual disability. Thus, Hall does not constitute “a development
    of fundamental significance that places beyond the State of Florida the power to
    impose a certain sentence,” 
    Walls, 213 So. 3d at 346
    .
    C. Hall is an Evolutionary Refinement
    Although this Court in Walls did not consider whether Hall falls within
    Witt’s second category of developments of fundamental significance—that is, a
    change of “sufficient magnitude” under the Stovall/Linkletter test—having receded
    from our conclusion that it falls within the first, we do so now.
    In order to determine whether a new rule of law is of “sufficient magnitude”
    to merit retroactive application, this Court considers the following three factors of
    the Stovall/Linkletter test adopted in Witt: “(a) the purpose to be served by the new
    rule; (b) the extent of reliance on the old rule; and (c) the effect on the
    administration of justice of a retroactive application of the new rule.” Witt, 
    387 So. 2d
    at 926. We agree with the reasons given by the Walls dissent as to why these
    factors counsel against the retroactive application of Hall:
    Hall should not be given retroactive effect under the Stovall/Linkletter
    test based on (a) Hall’s purpose of adjusting at the margin the
    - 15 -
    definition of IQ scores that evidence significant subaverage
    intellectual functioning, (b) the State’s reliance on Cherry’s holding in
    numerous cases over an extended period of time, and (c) the ongoing
    threat of major disruption to application of the death penalty resulting
    from giving retroactive effect to Hall as well as similar future changes
    in the law regarding aspects of the definition of intellectual disability.
    Walls, 
    213 So. 3d
    at 351 (Canady, J., dissenting) (footnote omitted).
    Moreover, our Court in Witt equated new rules of law that are of “sufficient
    magnitude” to merit retroactive application with “jurisprudential upheavals.” 
    Witt, 387 So. 2d at 929
    . Gideon v. Wainwright, 
    372 U.S. 335
    (1963)—which first
    announced that each state must provide counsel to every indigent defendant
    charged with a felony at all critical stages of the proceeding—“is the prime
    example of a law change included within this category.” 
    Witt, 387 So. 2d at 929
    .
    “In contrast to these jurisprudential upheavals are evolutionary refinements in the
    criminal law, affording new or different standards for the admissibility of evidence,
    for procedural fairness, for proportionality review of capital cases, and for other
    like matters.”
    Id. Hall is
    an evolutionary refinement of the procedure necessary to comply
    with Atkins. It merely clarified the manner in which courts are to determine
    whether a capital defendant is intellectually disabled and therefore ineligible for
    the death penalty. Roybal v. Chappell, No. 99CV2152-JM (KSC), 
    2014 WL 3849917
    , at *2 (S.D. Cal. Aug. 5, 2014) (stating that Hall was a clarification of
    Florida’s implementation of Atkins). It did not invalidate any statutory means for
    - 16 -
    imposing the death sentence, nor did it prohibit the states from imposing the death
    penalty against any new category of persons.
    Before Walls, this Court had been clear that evolutionary refinements do not
    apply retroactively. See, e.g., State v. Barnum, 
    921 So. 2d 513
    , 526 (Fla. 2005)
    (“Witt dictates that those decisions constituting ‘evolutionary refinements’ and not
    ‘jurisprudential upheavals’ should not be applied retroactively.” (quoting 
    Witt, 387 So. 2d at 929
    )); State v. Glenn, 
    558 So. 2d 4
    , 8 (Fla. 1990) (“Applying the
    principles of Witt, we conclude that Carawan was an evolutionary refinement of
    the law which should not have retroactive application.”). As an evolutionary
    refinement, Hall “do[es] not compel an abridgement of the finality of judgments.”
    
    Witt, 387 So. 2d at 929
    . It is not of sufficient magnitude to warrant retroactive
    application to cases on collateral review.
    In Walton v. State, 
    77 So. 3d 639
    (Fla. 2011), we rejected a claim that the
    United States Supreme Court’s decision in Porter v. McCollum, 
    558 U.S. 30
    (2009), warranted retroactive application. Porter was a fact-intensive decision in
    which the Supreme Court held that in a particular case, this Court had
    unreasonably applied the prejudice test for establishing ineffective assistance of
    counsel under Strickland v. Washington, 
    466 U.S. 688
    (1984). We held in Walton
    that
    the decision in Porter d[id] not concern a major change in
    constitutional law of fundamental significance. Rather, Porter
    - 17 -
    involved a mere application and evolutionary refinement and
    development of the Strickland analysis, i.e., it addressed a
    misapplication of Strickland. Porter, therefore, does not satisfy the
    retroactivity requirements of Witt.
    
    Walton, 77 So. 3d at 644
    . Similarly, as explained above, Hall involved a mere
    application and evolutionary refinement of the Atkins analysis and therefore does
    not satisfy the retroactivity requirements of Witt.
    D. Federal Law Does Not Require Retroactive Application of Hall
    Finally, we must consider whether federal law requires retroactive
    application of Hall. Under Teague v. Lane, 
    489 U.S. 288
    (1989), state courts must
    give retroactive effect to new substantive rules of federal constitutional law.
    Montgomery v. Louisiana, 
    136 S. Ct. 718
    , 728-29 (2016) (holding “that when a
    new substantive rule of [federal] constitutional law controls the outcome of a case,
    the Constitution requires state collateral review courts to give retroactive effect to
    that rule” under the first prong of Teague’s retroactivity analysis).5 Substantive
    rules set forth categorical constitutional guarantees that place certain criminal laws
    5. Although the federal standard for determining retroactivity under Teague
    is a two-pronged approach stating that courts must give retroactive effect to (1)
    new substantive rules of federal constitutional law and (2) new watershed rules of
    criminal procedure implicating the fundamental fairness and accuracy of the
    criminal proceeding, Montgomery held only that substantive rules of federal
    constitutional law must be applied retroactively by state courts. The Court in
    Montgomery explicitly declined to address “the constitutional status of Teague’s
    exception for watershed rules of 
    procedure.” 136 S. Ct. at 729
    .
    - 18 -
    and punishments altogether beyond the State’s power to impose.
    Id. at 729.
    In
    contrast, procedural rules are designed to enhance the accuracy of a conviction or
    sentence by regulating the manner of determining the defendant’s culpability and
    merely raise the possibility that someone convicted with use of the invalidated
    procedure might have been acquitted otherwise.
    Id. at 730.
    Because we have
    concluded that Hall announced a new procedural rule, which does not categorically
    place certain criminal laws and punishments altogether beyond the State’s power to
    impose but rather regulates only the manner of determining the defendant’s
    culpability, we conclude that federal law does not require retroactive application of
    Hall as a new substantive rule of federal constitutional law. Hall is similar to other
    nonretroactive “decisions [that] altered the processes in which States must engage
    before sentencing a person to death,” which “may have had some effect on the
    likelihood that capital punishment would be imposed” but which did not render “a
    certain penalty unconstitutionally excessive for a category of offenders.”
    Id. at 736.
    E. Receding from Walls
    Having concluded that Hall does not satisfy the Witt analysis for
    retroactivity and that it is not a new substantive rule of federal constitutional law
    requiring retroactive application to cases on collateral review, we are now faced
    with the question of whether the policy of stare decisis should yield.
    - 19 -
    We recently discussed the doctrine of stare decisis, stating:
    While this Court has consistently acknowledged the importance
    of stare decisis, it has been willing to correct its mistakes. In a recent
    discussion of stare decisis, we said:
    Stare decisis provides stability to the law and to the
    society governed by that law. Yet stare decisis does not
    command blind allegiance to precedent. “Perpetuating
    an error in legal thinking under the guise of stare decisis
    serves no one well and only undermines the integrity and
    credibility of the court.”
    Shepard v. State, 
    259 So. 3d 701
    , 707 (Fla. 2018) (quoting State v.
    Gray, 
    654 So. 2d 552
    , 554 (Fla. 1995)). Similarly, we have stated that
    “[t]he doctrine of stare decisis bends . . . where there has been an error
    in legal analysis.” Puryear v. State, 
    810 So. 2d 901
    , 905 (Fla. 2002).
    And elsewhere we have said that we will abandon a decision that is
    “unsound in principle.” Robertson v. State, 
    143 So. 3d 907
    , 910 (Fla.
    2014) (quoting Brown v. Nagelhout, 
    84 So. 3d 304
    , 309 (Fla. 2012)).
    It is no small matter for one Court to conclude that a
    predecessor Court has clearly erred. The later Court must approach
    precedent presuming that the earlier Court faithfully and competently
    carried out its duty. A conclusion that the earlier Court erred must be
    based on a searching inquiry, conducted with minds open to the
    possibility of reasonable differences of opinion. “[T]here is room for
    honest disagreement, even as we endeavor to find the correct answer.”
    Gamble v. United States, 
    139 S. Ct. 1960
    , 1986 (2019) (Thomas, J.,
    concurring).
    State v. Poole, 45 Fla. L. Weekly S41, S47-48 (Fla. Jan. 23, 2020), clarified, 45
    Fla. L. Weekly S121 (Fla. Apr. 2, 2020).
    We cannot escape the conclusion that this Court in Walls clearly erred in
    concluding that Hall applies retroactively. We say that based on our review of
    Hall, our state’s judicial precedents regarding retroactivity, and the decisions of
    federal habeas courts concluding that Hall does not apply retroactively. Based on
    - 20 -
    its incorrect legal analysis, this Court used Hall—which merely created a limited
    procedural rule for determining intellectual disability that should have had limited
    practical effect on the administration of the death penalty in our state—to
    undermine the finality of numerous criminal judgments. As in Poole, “[u]nder
    these circumstances, it would be unreasonable for us not to recede from [Walls’]
    erroneous holdings.”
    Id. at S48.
    “[O]nce we have chosen to reassess a precedent and have come to the
    conclusion that it is clearly erroneous, the proper question becomes whether there
    is a valid reason why not to recede from that precedent. . . . The critical
    consideration ordinarily will be reliance.”
    Id. But reliance
    interests are “at their acme in cases involving property and
    contract rights.” Payne v. Tennessee, 
    501 U.S. 808
    , 828 (1991). And
    reliance interests are lowest in cases—like this one—“involving
    procedural and evidentiary rules.” Id.; see also 
    Alleyne, 570 U.S. at 119
    (Sotomayor, J., concurring) (“[W]hen procedural rules are at issue
    that do not govern primary conduct and do not implicate the reliance
    interests of private parties, the force of stare decisis is reduced.”).
    Id. As the
    expectant potential beneficiary of the erroneous decision in Walls,
    Phillips has no concrete reliance interest; he has in no way changed his position in
    reliance on Walls. In this postconviction context, Phillips’s interest as an expectant
    potential beneficiary of Walls is set against all the interests that support
    maintaining the finality of Phillips’s judgment. The surviving victims, society-at-
    - 21 -
    large, and the State all have a weighty interest in not having Phillips’s death
    sentence set aside for the relitigation of his claim of intellectual disability based on
    Hall’s evolutionary refinement in the law.
    Thus, we conclude that we should not continue to apply the erroneous
    reasoning of Walls. And because Hall does not apply retroactively, it does not
    entitle Phillips to a reconsideration of whether he meets the first prong of the
    intellectual disability standard.
    F. Moore
    Phillips also asserts that he is entitled to a new determination as to whether
    he meets the adaptive deficits prong of the intellectual disability standard because
    the circuit court in 2006 and this Court in 2008 improperly relied on his adaptive
    strengths in concluding that he did not meet the adaptive deficits prong, assertedly
    in violation of the Supreme Court’s recent decision in Moore. But because Phillips
    has conclusively failed to establish that he meets the first prong of the intellectual
    disability standard, he cannot be found to be intellectually disabled even if he were
    entitled to a renewed determination on the second prong and could establish that he
    has deficits in adaptive behavior. As we have repeatedly stated, if a defendant fails
    to prove that he or she meets any one of the three prongs of the intellectual
    disability standard, he or she will not be found to be intellectually disabled. E.g.,
    - 22 -
    Jones v State, 
    231 So. 3d 374
    , 376 (Fla. 2017); Salazar v. State, 
    188 So. 3d 799
    ,
    812 (Fla. 2016). Thus, we need not address his Moore claim.
    III. CONCLUSION
    For these reasons, we affirm the circuit court’s order denying Phillips’s
    successive motion for postconviction relief. We also recede from our prior opinion
    in Walls and hold that Hall does not apply retroactively.
    It is so ordered.

    LABARGA, J., dissenting.
    Yet again, this Court has removed an important safeguard in maintaining the
    integrity of Florida’s death penalty jurisprudence. The result is an increased risk
    that certain individuals may be executed, even if they are intellectually disabled—a
    risk that this Court mitigated just three years ago by holding that the decision in
    Hall v. Florida, 
    572 U.S. 701
    (2014), is to be retroactively applied. See Walls v.
    State, 
    213 So. 3d 340
    (Fla. 2016). I strongly dissent to the majority’s decision to
    recede from Walls, and I write to underscore the unraveling of sound legal
    holdings in this most consequential area of the law.
    - 23 -
    Before the United States Supreme Court’s decision in Hall, under Florida
    law, individuals with an IQ score above 70 were barred from demonstrating that
    they were intellectually disabled. This “rigid rule,” as described by the Supreme
    Court, “creates an unacceptable risk that persons with intellectual disability will be
    executed, and thus is unconstitutional.” 
    Hall, 572 U.S. at 704
    . The Supreme Court
    stated:
    The Florida statute, as interpreted by its own courts, misuses IQ score
    on its own terms; and this, in turn, bars consideration of evidence that
    must be considered in determining whether a defendant in a capital
    case has intellectual disability. Florida’s rule is invalid under the
    Constitution’s Cruel and Unusual Punishment Clause.
    Id.
    at 723.
    In concluding that Florida’s intellectual disability law violated the Eighth
    Amendment, the Supreme Court pointedly criticized the “mandatory cutoff” that
    “disregards established medical practice in two interrelated ways”: (1) “tak[ing] an
    IQ score as final and conclusive evidence of a defendant’s intellectual capacity,
    when experts in the field would consider other evidence,” and (2) “rel[ying] on a
    purportedly scientific measurement of the defendant’s abilities, his IQ score, while
    refusing to recognize that the score is, on its own terms, imprecise.”
    Id. at 712.
    The “other evidence” to which the Court referred primarily consists of evidence of
    deficits in adaptive functioning, which is “an essential part of a sentencing court’s
    inquiry.”
    Id. at 724.
    The Supreme Court concluded: “This Court agrees with the
    - 24 -
    medical experts that when a defendant’s IQ test score falls within the test’s
    acknowledged and inherent margin of error, the defendant must be able to present
    additional evidence of intellectual disability, including testimony regarding
    adaptive deficits.”
    Id. at 723.
    The Court admonished that while “the States play a
    critical role in advancing protections and providing the Court with information that
    contributes to an understanding of how intellectual disability should be measured
    and assessed,” states do not have “unfettered discretion to define the full scope of
    the constitutional protection.”
    Id. at 719.
    The categorical prohibition of the execution of the intellectually disabled is
    not limited to those whose convictions and sentences became final after a certain
    date. However, the import of today’s decision is that some individuals whose
    convictions and sentences were final before Hall was decided, despite timely
    preserved claims of intellectual disability, are not entitled to consideration of their
    claims in a manner consistent with Hall. What this means is that an individual
    with significant deficits in adaptive functioning, and who under a holistic
    consideration of the three criteria for intellectual disability could be found
    intellectually disabled, is completely barred from proving such because of the
    timing of his legal process. This arbitrary result undermines the prohibition of
    executing the intellectually disabled.
    - 25 -
    “Considerations of fairness and uniformity make it very ‘difficult to justify
    depriving a person of his liberty or his life, under process no longer considered
    acceptable and no longer applied to indistinguishable cases.’ ” Witt v. State, 
    387 So. 2d 922
    , 925 (Fla. 1980) (quoting ABA Standards Relating to Postconviction
    Remedies 37 (Approved Draft 1968)). If Hall is not retroactively applied in a
    uniform manner, an intellectually disabled individual on Florida’s death row may
    eventually be put to death.
    I reject the majority’s conclusion that Hall was a mere procedural evolution
    in the law. When the law develops in such a manner as to clarify the criteria for
    intellectual disability—a status which poses an absolute bar to execution—this
    cannot simply be deemed “an evolutionary refinement.” Majority op. at 16. Walls
    properly concluded that Hall was a “development of fundamental significance that
    places beyond the State of Florida the power to impose a certain sentence—the
    sentence of death for individuals within a broader range of IQ scores than before.”
    
    Walls, 213 So. 3d at 346
    .
    What is especially troubling is that because this Court held Hall to be
    retroactive more than three years ago in Walls, some individuals have been granted
    relief pursuant to Walls and received consideration of their intellectual disability
    claims under the standard required by Hall. However, going forward, similarly
    - 26 -
    situated individuals will not be entitled to such consideration. This disparate
    treatment is patently unfair.
    In justifying its holding, the majority discusses the need for finality in the
    judicial process. I agree that finality is a fundamental component of a functioning
    judicial system. However, we simply cannot be blinded by an interest in finality
    when that interest leaves open the genuine possibility that an individual will be
    executed because he is not permitted consideration of his intellectual disability
    claim. “No legitimate penological purpose is served by executing a person with
    intellectual disability. To do so contravenes the Eighth Amendment, for to impose
    the harshest of punishments on an intellectually disabled person violates his or her
    inherent dignity as a human being.” 
    Hall, 572 U.S. at 708
    (citation omitted) (citing
    Atkins v. Virginia, 
    536 U.S. 304
    , 317-20 (2002)). “This is not to say that under
    current law persons with intellectual disability who ‘meet the law’s requirements
    for criminal responsibility’ may not be tried and punished. They may not,
    however, receive the law’s most severe sentence.”
    Id. at 709
    (citation omitted)
    (quoting 
    Atkins, 536 U.S. at 306
    ).
    Hall concluded with language that we would all do well to remember:
    The death penalty is the gravest sentence our society may
    impose. Persons facing that most severe sanction must have a fair
    opportunity to show that the Constitution prohibits their execution.
    Florida’s law contravenes our Nation’s commitment to dignity and its
    duty to teach human decency as the mark of a civilized world. The
    - 27 -
    States are laboratories for experimentation, but those experiments may
    not deny the basic dignity the Constitution protects.
    Hall, 572 U.S at 724.
    Today’s decision potentially deprives certain individuals of consideration of
    their intellectual disability claims, and it results in an inconsistent handling of these
    cases among similarly situated individuals.
    For these reasons, I dissent.
