    McDONALD, Justice.
    Petitioner James Dorsey shot and killed a woman when he was eighteen
    years and five days old. He was found guilty of murder in the first degree and
    was sentenced to a mandatory term of life in prison without the possibility of
    parole. Dorsey contends this sentence violates his state constitutional right to
    be free from “cruel and unusual punishment.” Iowa Const. art. I, § 17. He argues
    the state constitution prohibits imposing a mandatory punishment on a young
    adult offender and instead requires the district court to hold an individualized
    sentencing hearing before imposing any sentence. He further argues his life
    sentence without the possibility of parole is grossly disproportionate to the crime.
    For the reasons expressed below, we affirm Dorsey’s sentence.
    I.
    On September 3, 1984, Dorsey, accompanied by two other men, entered
    the Des Moines home of Juanita Weaver with a shotgun. Dorsey went to Weaver’s
    home to retrieve a revolver that Dorsey and Weaver’s son had previously stolen
    from Dorsey’s uncle. After Dorsey entered the home, he realized Weaver’s son
    was not there. Weaver went into the living room upon hearing noises in the home
    and came upon Dorsey and the two other men. Dorsey fired at Weaver and
    missed. Weaver ran into the bathroom, and Dorsey followed, where he shot
    Weaver at close range and killed her. The three men fled the scene and went to
    a party but were eventually arrested. A jury found Dorsey guilty of murder in the
    first degree, and the district court sentenced Dorsey to a mandatory term of life
    in prison without the possibility of parole.
    4
    In the nearly thirty-eight years since the murder, Dorsey has challenged
    his conviction and resulting mandatory life sentence on numerous occasions.
    His conviction was first affirmed on direct appeal in February 1986. In
    September 1986, Dorsey filed two separate but overlapping applications for
    postconviction relief. The applications were treated as a single application and
    dismissed as meritless in March 1994. Dorsey filed a second application for
    postconviction relief in November 1994, which the district court dismissed as
    time-barred. Dorsey filed his third and fourth applications for postconviction
    relief in January 1999 and October 2008, which were also dismissed as
    time-barred.
    In January 2014, Dorsey filed a motion to correct an illegal sentence in
    the underlying criminal case. In that motion, he contended that his mandatory
    life sentence without the possibility of parole inflicted cruel and unusual
    punishment upon him in violation of the Federal and State Constitutions. In
    support of his argument, Dorsey relied on United States Supreme Court
    precedents stating that juvenile offenders have diminished culpability and better
    chances for reform and that “the penological justifications for imposing the
    harshest sentences on juvenile offenders” are diminished and, in some
    instances, categorically prohibited. Miller v. Alabama, 
    567 U.S. 460
    , 472 (2012);
    see 
    id. at 489
     (“By requiring that all children convicted of homicide receive
    lifetime incarceration without possibility of parole, regardless of their age and
    age-related    characteristics   and    the     nature   of    their   crimes,     the
    mandatory-sentencing      schemes      before   us   violate    this   principle    of
    5
    proportionality, and so the Eighth Amendment’s ban on cruel and unusual
    punishment.”); Graham v. Florida, 
    560 U.S. 48
    , 82 (2010) (“The Constitution
    prohibits the imposition of a life without parole sentence on a juvenile offender
    who did not commit homicide. A State need not guarantee the offender eventual
    release, but if it imposes a sentence of life it must provide him or her with some
    realistic opportunity to obtain release before the end of that term.”); Roper v.
    Simmons, 
    543 U.S. 551
    , 578 (2005) (“The Eighth and Fourteenth Amendments
    forbid imposition of the death penalty on offenders who were under the age of 18
    when their crimes were committed.”). Dorsey recognized that he was not a
    juvenile at the time of the offense, but he argued “[t]he courts in Iowa are
    expanding on the ruling of the United States Supreme Court” by applying the
    same rationale in other contexts. The district court denied the motion. Although
    Dorsey raised both a federal and state constitutional claim in his motion, the
    district court’s order referenced only the federal claim.
    The filing at issue in this case is Dorsey’s fifth application for
    postconviction relief. In his application, Dorsey argued that his mandatory life
    sentence without the possibility of parole violated the federal and state
    constitutional prohibitions against cruel and unusual punishment. In support
    of his claims, Dorsey relied on this court’s more recent juvenile sentencing
    jurisprudence applying and extending Roper v. Miller, Graham v. Florida, and
    Miller v. Alabama. See generally State v. Roby, 
    897 N.W.2d 127
     (Iowa 2017);
    State v. Sweet, 
    879 N.W.2d 811
     (Iowa 2016); State v. Louisell, 
    865 N.W.2d 590
    (Iowa 2015); State v. Seats, 
    865 N.W.2d 545
     (Iowa 2015); State v. Lyle, 854
    
    6 N.W.2d 378
     (Iowa 2014); State v. Ragland, 
    836 N.W.2d 107
     (Iowa 2013); State v.
    Pearson, 
    836 N.W.2d 88
     (Iowa 2013); State v. Null, 
    836 N.W.2d 41
     (Iowa 2013).
    Dorsey relied specifically on State v. Lyle, in which this court held that “all
    mandatory minimum sentences of imprisonment for youthful offenders are
    unconstitutional under the cruel and unusual punishment clause in article I,
    section 17 of our constitution.” 854 N.W.2d at 400. He also relied on State v.
    Sweet, which created “a categorical rule that juvenile offenders may not be
    sentenced to life without the possibility of parole under article I, section 17 of
    the Iowa Constitution.” 879 N.W.2d at 839. In his application, Dorsey recognized
    that these holdings explicitly applied only to juvenile offenders, but he argued
    the cases should be extended or their holdings modified to provide relief for
    young adult offenders. He argued Lyle and Sweet should preclude the imposition
    of mandatory punishments on young adult offenders and should require
    individualized sentencing hearings for all young adult offenders, including those
    convicted of murder in the first degree.
    The district court declined to provide Dorsey any relief and granted the
    State’s motion for summary disposition of the claims. The district court held
    Dorsey’s application for postconviction relief was barred by the three-year statute
    of limitations set forth in Iowa Code section 822.3 (2019). The district court also
    concluded that, to the extent Dorsey’s claims could be considered a motion to
    correct an illegal sentence, the claims were barred res judicata because Dorsey
    raised the same claims in his 2014 motion to correct an illegal sentence. Finally,
    the district court concluded that Dorsey was not entitled to any relief on the
    7
    merits because Lyle and Sweet applied only to juvenile offenders and not adult
    offenders. Dorsey timely filed his notice of appeal, and we retained the case.
    II.
    When an offender files an application for postconviction relief and
    “complains his sentence is illegal . . . the claim ‘is not a postconviction relief
    action.’ ” Bonilla v. State, 
    791 N.W.2d 697
    , 699 (Iowa 2010) (quoting Veal v. State,
    
    779 N.W.2d 63
    , 65 (Iowa 2010)). Instead, the application for postconviction relief
    is treated as a motion to correct an illegal sentence. 
    Id.
     at 699–700. We therefore
    construe Dorsey’s application for postconviction relief as a motion to correct an
    illegal sentence. There is no appeal as a matter of right from the denial of a
    motion to correct an illegal sentence. See State v. Propps, 
    897 N.W.2d 91
    , 96–97
    (Iowa 2017). However, when a case is initiated by a notice of appeal, but another
    form of review is proper, we need not dismiss the action and may proceed instead
    as though the proper form of review was requested. Iowa R. App. P. 6.108. We
    treat Dorsey’s “notice of appeal and accompanying briefs as a petition for writ of
    certiorari, as we conclude that appeals from a motion to correct an illegal
    sentence are most appropriately fashioned in this manner. We grant the petition
    for writ of certiorari.” Propps, 897 N.W.2d at 97.
    III.
    The district court denied Dorsey’s challenge to his mandatory life sentence
    without the possibility of parole on three grounds. First, the district court held
    that Dorsey’s application for postconviction relief was barred by the three-year
    statute of limitations set forth in Iowa Code section 822.3. Second, the district
    8
    court held Dorsey’s claims were barred res judicata because Dorsey had raised
    the same claims in his 2014 motion to correct an illegal sentence. Finally, the
    district court concluded that Dorsey was not entitled to any relief on the merits.
    We address each ruling in turn.
    A.
    The statute of limitations governing postconviction-relief proceedings does
    not bar Dorsey’s constitutional challenge to his sentence. In general, an
    application for postconviction relief “must be filed within three years from the
    date the conviction or decision is final or, in the event of an appeal, from the date
    the writ of procedendo is issued.” 
    Iowa Code § 822.3
    . But the statute of
    limitations for postconviction-relief proceedings is not applicable here. As
    discussed above, the district court should have treated Dorsey’s application for
    postconviction relief as a motion to correct an illegal sentence. See Bonilla, 791
    N.W.2d at 699–700. Because an offender can file a motion to correct an illegal
    sentence at any time, the motion “is not governed by the postconviction statute
    of limitations.” Veal, 
    779 N.W.2d at 65
    . The district court thus erred to the extent
    it held that Dorsey’s claims were barred by section 822.3. See 
    id.
     (stating that
    when a claim of an illegal sentence is raised in an application for postconviction
    relief, even when “not labeled as such, the district court . . . should treat [the]
    application for postconviction relief as a challenge to an illegal sentence that is
    not subject to the three-year statute of limitations in Iowa Code section 822.3”).
    9
    B.
    Nor can we conclude Dorsey’s challenge to his sentence is barred res
    judicata. Under Iowa law, “res judicata embraces two concepts: claim preclusion
    and issue preclusion.” Braunschweig v. Fahrenkrog, 
    773 N.W.2d 888
    , 893 (Iowa
    2009). “The general rule of claim preclusion holds that a valid and final judgment
    on a claim bars a second action on the adjudicated claim or any part thereof.”
    Pavone v. Kirke, 
    807 N.W.2d 828
    , 835 (Iowa 2011). “[I]ssue preclusion prevents
    parties to a prior action in which judgment has been entered from relitigating in
    a subsequent action issues raised and resolved in the previous action.” Hunter v.
    City of Des Moines, 
    300 N.W.2d 121
    , 123 (Iowa 1981) (footnote omitted). “The
    term ‘issue preclusion’ is used interchangeably with the term ‘collateral
    estoppel.’ ” 
    Id.
     at 123 n.2.
    We cannot conclude the doctrines of claim preclusion and issue preclusion
    bar consideration of Dorsey’s claim. First, Dorsey’s 2014 motion to correct an
    illegal sentence raised federal and state constitutional claims, but the district
    court’s order addressed only Dorsey’s federal claim. There was no ruling on
    Dorsey’s state constitutional claim in the prior motion. Second, following the
    denial of Dorsey’s 2014 motion, this court created new categorical rules
    regarding juvenile sentencing. In Lyle, this court held that “all mandatory
    minimum sentences of imprisonment for youthful offenders are unconstitutional
    under the cruel and unusual punishment clause in article I, section 17 of our
    constitution.” 854 N.W.2d at 400. Two years later, in Sweet, this court extended
    Lyle and created “a categorical rule that juvenile offenders may not be sentenced
    10
    to life without the possibility of parole under article I, section 17 of the Iowa
    Constitution.” 879 N.W.2d at 839. Dorsey seeks to take advantage of these new
    categorical rules in our state constitutional jurisprudence and extend the
    rationale of Lyle and Sweet to young adult offenders such as himself. In other
    cases, we have allowed article I, section 17 challenges to the constitutionality of
    sentences following changes in our jurisprudence, and we see no reason to
    uniquely preclude Dorsey’s challenge. The district court erred in holding
    Dorsey’s claim based on new law was barred.
    C.
    We next address the district court’s alternative ruling on the merits of
    Dorsey’s challenge to his sentence. In the district court, Dorsey raised federal
    and state constitutional challenges to his sentence. On appeal, Dorsey raises
    only his state constitutional claim arising under article I, section 17 of the Iowa
    Constitution, which prohibits the infliction of “cruel and unusual punishment.”
    Dorsey contends the Iowa Constitution categorically prohibits the imposition of
    a mandatory sentence on a young adult offender and instead requires an
    individualized sentencing hearing. We conclude the district court did not err in
    denying Dorsey’s state constitutional claim on the merits.
    Generally, “[t]he legislature possesses the inherent power to prescribe
    punishment for crime, and the sentencing authority of the courts is subject to
    that power.” State v. Iowa Dist. Ct. for Shelby Cnty., 
    308 N.W.2d 27
    , 30 (Iowa
    1981). It is solely the legislature’s prerogative to set punishments that balance
    the state’s interest in achieving certain penological interests with the other
    11
    interests related to the administration of criminal justice. The legislature’s
    prerogative to set punishments is circumscribed only by the Federal and State
    Constitutions. In Sweet and Lyle, this court held article I, section 17
    circumscribes the legislature’s prerogative in imposing certain punishments on
    juvenile offenders. See Sweet, 879 N.W.2d at 839; Lyle, 854 N.W.2d at 400.
    The Sweet and Lyle courts offered several justifications for the creation of
    this categorical limitation. See, e.g., Sweet, 879 N.W.2d at 830–34 (identifying
    fourteen critical points drawn from the federal caselaw and the three critical
    principles distilled from the Iowa caselaw). Among these justifications were
    medical literature tending to show the human brain continues to develop until
    the age of twenty-five and medical and social science literature tending to show
    juveniles think and act differently than adults. See, e.g., Null, 836 N.W.2d at 55
    (stating the rationale is based on (1) recent scientific evidence showing “the
    human brain continues to mature into the early twenties,” and (2) a finding that
    young people generally “lack the ability to properly assess risks and engage in
    adult-style self-control”).
    While Dorsey acknowledges that our precedents in this area create
    categorical rules applicable only to juvenile offenders and that he was not a
    juvenile at the time of the offense, he argues the same medical and social science
    literature applies with equal force to adult offenders under age twenty-five. At
    minimum, he argues someone like him, who was only eighteen years and five
    days old at the time of his offense, is entitled to a Miller sentencing hearing before
    the imposition of a life sentence.
    12
    But the arguments by Dorsey and the dissent are foreclosed by the same
    precedents on which they rely. As we stated in Lyle:
    [O]ur holding today has no application to sentencing laws affecting
    adult offenders. Lines are drawn in our law by necessity and are
    incorporated into the jurisprudence we have developed to usher the
    Iowa Constitution through time. This case does not move any of the
    lines that currently exist in the sentencing of adult offenders.
    854 N.W.2d at 403. We later reiterated that “the line between being a juvenile
    and an adult was drawn for cruel and unusual punishment purposes at eighteen
    years of age.” Seats, 865 N.W.2d at 556–57. And in Sweet we stated that “[t]he
    qualities that distinguish juveniles from adults do not disappear when an
    individual turns eighteen, but society has generally drawn the line at eighteen
    for the purposes of distinguishing juveniles from adults.” 879 N.W.2d at 831.
    The categorical constitutional distinction this court drew between
    juveniles and adults was based on the long-accepted legal categorical distinction
    drawn between juveniles and adults. “We have long known juveniles are different
    from adults.” Goodwin v. Iowa Dist. Ct. for Davis Cnty., 
    936 N.W.2d 634
    , 652
    (Iowa 2019) (McDonald, J., concurring specially). “The legislature already
    accounted for this by creating a separate juvenile justice system to address the
    different and particular needs of juvenile offenders.” Id. at 653. This includes
    waiver and reverse waiver provisions that afford the district court discretion in
    determining whether a juvenile should be prosecuted as a juvenile or as an adult
    based on the particular circumstances of the juvenile. See 
    Iowa Code §§ 232.8
    ,
    .45. The legislature also, in accord with our caselaw, distinguishes between
    juvenile and adult offenders with respect to sentencing for murder in the first
    13
    degree. Adults convicted of murder in the first degree, such as Dorsey, are
    required to serve mandatory terms of life imprisonment without the possibility
    of parole. See 
    id.
     § 707.2(2); id. § 902.1(1). Whereas, those under the age of
    eighteen at the time of the offense, may be eligible for parole. Id. § 902.1(2). And,
    as we explained in Lyle, juveniles are treated differently than adults in a variety
    of other contexts outside the area of criminal law. See Lyle, 854 N.W.2d at 388–
    89 (cataloging laws treating juveniles differently than adults).
    The bright-line constitutional distinction between juvenile offenders and
    adult offenders for purposes of article I, section 17 has been clear from the
    outset. In reliance on that bright-line rule, the court of appeals repeatedly has
    considered and rejected the same argument Dorsey and the dissent advance
    here. See, e.g., McGuire v. State, No. 21–0031, 
    2022 WL 470841
    , at *4 (Iowa Ct.
    App. Feb. 16, 2022); Hayes v. Polk Cnty. Dist. Ct., No. 19–1660, 
    2021 WL 3378674
    , at *1 (Iowa Ct. App. Aug. 4, 2021); Mozie v. State, No. 20–0024, 
    2021 WL 810962
    , at *1 (Iowa Ct. App. Mar. 3, 2021); Shuford v. Iowa Dist. Ct. for Scott
    Cnty., No. 18–1434, 
    2020 WL 1879663
    , at *3 (Iowa Ct. App. Apr. 15, 2020);
    Swan v. State, No. 17–0877, 
    2018 WL 6706212
    , at *3 (Iowa Ct. App. Dec. 19,
    2018); Nassif v. State, No. 17–0762, 
    2018 WL 3301828
    , at *1 (Iowa Ct. App.

    , at *2 (Iowa Ct.
    App. June 21, 2017); State v. Clayton, No. 13–1771, 
    2014 WL 5862075
    , at *5
    (Iowa Ct. App. Nov. 13, 2014). “Considerations of efficiency and certainty require
    a bright line separating adults from juveniles.” United States v. Marshall, 
    736 F.3d 492
    , 500 (6th Cir. 2013). We adhere to the bright-line distinction drawn in
    14
    our caselaw and repeatedly followed by the court of appeals. Dorsey is not
    entitled to any relief on this claim.
    IV.
    Dorsey also asserts a separate challenge to his sentence for the first time
    on appeal. Dorsey argues that his sentence of life imprisonment without the
    possibility of parole is “grossly disproportionate” to the crime of murder in the
    first degree and therefore constitutes cruel and unusual punishment in violation
    of article I, section 17 of the Iowa Constitution. “Where, as here, the claim is that
    the sentence itself is inherently illegal, whether based on constitution or statute,
    we believe the claim may be brought at any time.” State v. Bruegger, 
    773 N.W.2d 862
    , 872 (Iowa 2009). This includes a claim being brought for the first time on
    appeal. See 
    id.
     We thus turn to the merits of the claim.
    We employ a three-part test to determine whether a sentence is grossly
    disproportionate to the underlying offense. The first step is a “threshold” inquiry
    which involves “a balancing of the gravity of the crime against the severity of the
    sentence.” 
    Id. at 873
    . If the sentence being reviewed does not “raise an inference
    of gross disproportionality,” then the inquiry ends and “[n]o further analysis is
    required.” State v. Wickes, 
    910 N.W.2d 554
    , 572 (Iowa 2018). If the threshold
    inquiry is satisfied, step two requires “an intrajurisdictional analysis to compare
    the challenged sentence to sentences of other crimes within our jurisdiction.” 
    Id.
    Step three requires “an interjurisdictional review and examine the sentences for
    similar crimes in other jurisdictions.” 
    Id.
    15
    At the threshold stage of analysis, our primary task is to balance “the
    gravity of the crime against the severity of the sentence.” Bruegger, 
    773 N.W.2d at 873
    . In balancing these competing considerations, we consider several general
    principles. First, “we owe substantial deference to the penalties the legislature
    has established for various crimes.” State v. Oliver, 
    812 N.W.2d 636
    , 650 (Iowa
    2012). “Criminal punishment can have different goals, and choosing among them
    is within a legislature’s discretion.” Graham, 560 U.S. at 71. Second, “it is rare
    that a sentence will be so grossly disproportionate to the crime as to satisfy the
    threshold inquiry and warrant further review.” Oliver, 812 N.W.2d at 650. Third,
    “a recidivist offender is more culpable and thus more deserving of a longer
    sentence than a first-time offender.” Id. And finally, “the unique features of a
    case can ‘converge to generate a high risk of potential gross disproportionality.’ ”
    Id. at 651 (quoting Bruegger, 
    773 N.W.2d at 884
    ).
    As a general matter, the sentence of life imprisonment without the
    possibility of parole for the crime of murder in the first degree does not raise an
    inference of gross disproportionality. The prohibition against cruel and unusual
    punishment “does not require a precise calibration of crime and punishment.”
    United States v. Graciani, 
    61 F.3d 70
    , 76 (1st Cir. 1995). Rather, the prohibition
    “gives rise to a ‘narrow proportionality principle,’ forbidding only extreme
    sentences that are significantly disproportionate to the underlying crime.” 
    Id.
    (citation omitted) (quoting Harmelin v. Michigan, 
    501 U.S. 957
    , 997 (1991)
    (Kennedy, J., concurring in part and concurring in the judgment)). “[T]he taking
    of innocent life is considered the greatest universal wrong.” State v. Izzolena, 609
    
    16 N.W.2d 541
    , 550 (Iowa 2000) (en banc). And the proportionate response is to
    impose the greatest punishment allowed under our law, life imprisonment
    without the possibility of parole. See State v. Fitz, 
    265 N.W.2d 896
    , 899 (Iowa
    1978) (rejecting challenge to life sentence for murder); State v. Fuhrmann, 
    261 N.W.2d 475
    , 479–80 (Iowa 1978) (en banc) (“Life imprisonment for first-degree
    murder is not so disproportionate to the seriousness of the offense as to shock
    the conscience or sense of justice.”).
    And there is nothing unique about the facts of this case that raise an
    inference of gross disproportionality. Dorsey entered Weaver’s home armed with
    a shotgun in search of her son. When Weaver refused to disclose her son’s
    whereabouts, Dorsey shot at her. Weaver fled into the bathroom, and Dorsey
    followed her. He reloaded the shotgun and killed Weaver with a close-range shot
    that left “a massive shotgun wound in [her] face and arm.” Based on these facts,
    the jury found Dorsey guilty of committing a willful, deliberate, and premeditated
    murder. Dorsey’s willful, deliberate, and premeditated murder of an unarmed
    woman in her own home justifies the most severe sentence allowed under our
    law. There is no inference of gross disproportionality here. See Fuhrmann, 
    261 N.W.2d at
    479–80; see also People v. Blackwell, 
    207 Cal. Rptr. 3d 444
    , 472 (Ct.
    App. 2016) (“The sentence in this case, though undoubtedly harsh, does not
    shock the conscience and is not disproportionate. Blackwell was convicted of
    first   degree   murder   with   special    circumstances.   First   degree   special
    circumstance murder, viewed in the abstract, is perhaps the most serious offense
    under California law, and the facts of this particular case do not remove it from
    17
    this category.”); People v. Castillo, ___ P.3d ___, ___ , 
    2022 WL 480893
    , at *8

    PETITION     FOR    WRIT    OF    CERTIORARI     GRANTED     AND    WRIT

    18
    #19–1917, Dorsey v. State
    APPEL, Justice (dissenting).
    I respectfully dissent. In my view, the proper disposition in this case under
    the cruel and unusual punishment clause of the Iowa Constitution is a remand
    to the district court for an individualized hearing to determine whether the State
    can show that the defendant is not entitled mitigation based upon the
    characteristics of youth.
    I. Introduction.
    In this case, we must decide if the evolving science regarding the
    characteristics of youth above the age of eighteen must be considered in cases
    involving the imposition of a sentence of life without possibility of parole in order
    to avoid a violation of the cruel and unusual punishment clause of article I,
    section 17 of the Iowa Constitution. If the answer to the threshold question is
    no, that is the end of the matter. If the answer is yes, the next question is: how
    should the science be applied in our cruel and unusual punishment
    jurisprudence?
    In order to answer these questions, I first provide a brief review of the
    sentence of life without possibility of parole. Second, I review the cruel and
    unusual punishment jurisprudence for offenders under the age of eighteen
    developed by the United States Supreme Court and this court. Third, I examine
    scientific developments related to the development of adolescents since Roper v.
    Simmons, 
    543 U.S. 551
     (2005). Fourth, I examine relevant caselaw and
    commentary advancing the idea that science, which had such a profound impact
    19
    on our jurisprudence related to cruel and unusual punishment for juveniles,
    should also apply to adolescent youth over the age of eighteen. Finally, I consider
    choices available to the court in applying the science and provide an analysis of
    why I conclude that an individualized hearing on the application of science is the
    proper approach in this case.
    II. Life-Without-Possibility-of-Parole Sentences.
    The   United    States    imposes    more   life-without-possibility-of-parole
    sentences than any other country in the world by far. William W. Berry III,
    Evolved Standards, Evolving Justices? The Case for a Broader Application of the
    Eighth Amendment, 
    96 Wash. U. L. Rev. 105
    , 109 (2018). The United States has
    approximately    50,000     persons    serving    life-without-possibility-of-parole
    sentences, while the runner-up countries have only a few hundred. 
    Id.
     The
    United States is the only country in the world that allows life-without-possibility-
    of-parole sentences on juvenile offenders. 
    Id. at 143
    .
    Life without possibility of parole has been frequently compared to the
    death penalty. As John Stuart Mill observed centuries ago:
    What comparison can there really be, in point of severity, between
    consigning a man to the short pang of a rapid death, and immuring
    him in a living tomb, there to linger out what may be a long life in
    the hardest and most monotonous toil, without any of its alleviations
    or rewards-debarred from all pleasant sights and sounds, and cut
    off from all earthly hope, except a slight mitigation of bodily
    restraint, or a small improvement of diet?
    William W. Berry III, Life-With-Hope Sentencing: The Argument for Replacing Life-
    Without-Parole Sentences with Presumptive Life Sentences, 
    76 Ohio St. L.J. 1051
    ,
    20
    1053 n.7 (2015) (quoting John Stuart Mill, Speech in Favor of Capital Punishment
    Before Parliament (Apr. 21, 1868)).
    Pope Francis also agreed with this comparison; he has concluded that “[a]
    life sentence is just a death penalty in disguise.” Address of Pope Francis to the
    Delegates of the International Association of Penal Law, Vatican (Oct. 23, 2014),
    https://www.vatican.va/content/francesco/en/speeches/2014/october/docu
    ments/papa-francesco_20141023_associazione-internazionale-diritto-
    penale.html [https://perma.cc/P42Z-P2NW]; see also Brittany L. Deitch, Life
    Without Parole as Death Without Dignity, 
    72 Ala. L. Rev. 327
    , 328 n.1 (2020).
    Some state courts have recognized the despair and hopelessness of life-
    without-possibility-of-parole sentences. For example, the Supreme Court of
    Nevada declared with respect to a life in prison without possibility of parole for
    a juvenile defendant:
    Denial of [the opportunity to seek parole] means denial of hope; it
    means that good behavior and character improvement are
    immaterial; it means that whatever the future might hold in store
    for the mind and spirit of [the offender], he will remain in prison for
    the rest of his days.
    Naovarath v. State, 
    779 P.2d 944
    , 944 (Nev. 1989). The court went on to hold
    that a sentence of life imprisonment without possibility of parole for juvenile
    offenders was unconstitutional on both state and federal grounds. 
    Id.
     at 949 n.6.
    Life-without-possibility-of-parole   sentences   deprive   the   individual’s
    personhood or humanity. As noted by one observer, the essence of personhood
    or humanity, as culled from leading philosophers:
    [I]t is a sense of self that conveys the capacity and moral right to
    make choices and hence be self-determining. Self-determination, in
    21
    turn, both finds expression in and presupposes . . . some degree of
    (1) autonomy, defined as the capacity to influence one’s environment
    and hence shape one’s fate, (2) security, defined as the capacity to
    find or create stability in one’s world and hence shelter oneself from
    harm, and (3) relatedness to others, defined as the capacity for fees
    for oneself and others and hence to have caring and constructive
    relationships.
    Robert Johnson, Death Work: A Study of the Modern Execution Process 204 (2d
    ed. 1998).
    By the above measure, life without possibility of parole is inhumane and
    the distinction between death by incarceration and death by execution is closed
    if not eliminated. Commentators have described a life sentence without
    possibility of parole as the “new death penalty” or “the other death penalty” or
    as being sentenced to be “buried alive.” See Marie Gottschalk, Sentenced to Life:
    Penal Reform and the Most Severe Sanctions, 9 Ann. Rev. L. & Soc. Sci. 353, 354
    (2013); see also Miller v. Alabama, 
    567 U.S. 460
    , 474–75 (2012) (noting that life-
    without-parole sentences for juveniles is akin to the death penalty).
    Some persons sentenced to life without possibility of parole agree. Scholar
    Margaret E. Leigey has collected statements from such prisoners. See Margaret
    E. Leigey, The Forgotten Men: Serving a Life Without Parole Sentence (2015). One
    prisoner declared that a person serving life without possibility of parole “would
    be a lot better off if they just went on and executed him as opposed to the life
    without parole because that’s torture.” Id. at 15. Another prisoner stated that “it
    would be better if they just take us out back and shot us,” and referred to the
    sentence as “the hard death penalty.” Id. Given the extraordinarily severe
    consequences of a life-without-possibility-of-parole sentence, courts have
    22
    remarkably upheld prisoners’ decisions of preferring the death penalty to life in
    prison. See Autry v. McKaskle, 
    727 F.2d 358
    , 363 (5th Cir. 1984) (per curiam)
    (noting prisoners preference for death over life in prison not irrational); Smith v.
    State, 
    686 N.E.2d 1264
    , 1273 (Ind. 1997) (collecting cases and concluding that
    prisoners preference for death over life in prison not per se irrational); Wayne A.
    Logan, Proportionality and Punishment: Imposing Life Without Parole on Juveniles,
    
    33 Wake Forest L. Rev. 681
    , 712 (1998); see also John H. Blume, Killing the
    Willing: “Volunteers,” Suicide and Competency, 
    103 Mich. L. Rev. 939
     (2005).
    III. Overview of Cruel and Unusual Punishment Jurisprudence
    Applicable to Juveniles Under Eighteen Years of Age.
    A. United States Supreme Court Precedent.
    1. Evolving standards of decency. I begin by briefly traveling on a familiar
    path. The United States Supreme Court has repeatedly declared that the content
    of the Cruel and Unusual Punishment Clause is not static but instead derives
    meaning from “evolving standards of decency that mark the progress of a
    maturing society.” Estelle v. Gamble, 
    429 U.S. 97
    , 102 (1976) (quoting Trop v.
    Dulles, 
    356 U.S. 86
    , 101 (1958) (plurality opinion)); see also Weems v. United
    States, 
    217 U.S. 349
    , 378 (1910). As explained by the Supreme Court in Kennedy
    v. Louisiana, “[T]he standard of extreme cruelty is not merely descriptive, but
    necessarily embodies a moral judgment. The standard itself remains the same,
    but its applicability must change as the basic mores of society change.” 
    554 U.S. 407
    , 419 (2008) (quoting Furman v. Georgia, 
    408 U.S. 238
    , 382 (1972)
    (per curiam) (Burger, C.J., dissenting)).
    23
    There can be no question that recent cases of the Supreme Court have
    evolved even in a relatively short period of time, particularly when dealing with
    harsh sentences of juvenile offenders. For example, in Thompson v. Oklahoma,
    the Supreme Court held that the death penalty could not be constitutionally
    applied to persons under the age of sixteen. 
    487 U.S. 815
    , 838 (1988). In the
    following year, the Supreme Court rejected the extension of the prohibition to
    persons aged sixteen to eighteen. See Stanford v. Kentucky, 
    492 U.S. 361
    , 378–
    79 (1989), abrogated by Roper, 
    543 U.S. 551
    . But a little more than fifteen years
    later, the Supreme Court overruled Stanford and extended the prohibition to
    persons under the age of eighteen. See Roper, 
    543 U.S. at
    563–64 (conducting
    the inquiry into “our society’s evolving standards of decency,” and recognizing
    evidence of a “national consensus against the death penalty for juveniles”).
    Similarly, in Penry v. Lynaugh, the Supreme Court declined to mandate a
    categorical exemption from the death penalty for the mentally disabled. 
    492 U.S. 302
    , 335 (1989), abrogated by Atkins v. Virginia, 
    536 U.S. 304
     (2002). But less
    than fifteen years later, in Atkins v. Virginia, the Court reversed course and
    declared categorically that the death penalty could not be imposed on the
    mentally disabled. 
    536 U.S. at 321
    . The cruel and unusual punishment cases of
    the Supreme Court clearly leave room for constitutional growth and
    development.
    Applying evolving standards in three important cases, the Supreme Court
    determined that, notwithstanding historic practice, the Cruel and Unusual
    Punishment Clause of the Eighth Amendment categorically prohibited
    24
    imposition of the death penalty to persons under eighteen, Roper, 
    543 U.S. at
    574–75; categorically prohibited life without possibility of parole for juveniles
    who commit a nonhomicidal crime, Graham v. Florida, 
    560 U.S. 48
    , 79 (2010);
    and generally held that a person under eighteen years of age who committed
    homicide could not be sentenced to life without possibility of parole unless shown
    to be a rare juvenile who was incorrigible. Miller, 
    567 U.S. at 479
    . These dynamic
    cases set the framework for analysis of the question of whether the harshest
    irrevocable punishments may be imposed against young offenders.
    2. Roper v. Simmons. In Roper, the Supreme Court considered whether
    the death penalty could be constitutionally imposed on a juvenile who committed
    the crime while under the age of eighteen. 
    543 U.S. at
    574–75. For the
    prosecution, the answer to this question was obvious. At trial, the prosecution
    argued that the young age of the offender was an aggravating factor. 
    Id. at 558
    .
    The prosecution told the jury, “Think about age. Seventeen years old. Isn’t that
    scary? Doesn’t that scare you? Mitigating? Quite the contrary I submit. Quite
    the contrary.” 
    Id.
    In categorically declaring that the death penalty could not constitutionally
    be imposed on any juvenile under the age of eighteen, the Supreme Court in
    Roper unequivocally rejected the prosecution’s age-as-an-aggravating-factor
    theory. 
    Id.
     at 572–73. The Roper Court did so in part by relying on developing
    neuroscience and social psychology. 
    Id.
     at 569–70. First, the Roper Court
    emphasized that persons eighteen and under lack maturity and have an
    underdeveloped sense of responsibility. 
    Id. at 569
    . Second, the Roper Court
    25
    stressed that juveniles are “more vulnerable or susceptible to negative influences
    and outside pressures, including peer pressure.” 
    Id.
     (citing Eddings v. Oklahoma,
    
    455 U.S. 104
    , 115 (1982)). Finally, the Roper Court observed that “the character
    of a juvenile is not as well formed as that of an adult.” Id. at 570. According to
    Roper, “From a moral standpoint it would be misguided to equate the failings of
    a minor with those of an adult, for a greater possibility exists that a minor’s
    character deficiencies will be reformed.” Id.
    Given these factors, not only was age not an aggravating factor as argued
    by the Roper prosecution, but age under the United States Constitution was
    categorically a mitigating factor. See id. at 569–73. In so holding, the Supreme
    Court favored science over rhetoric. In light of the neuroscience and social
    psychology developments that demonstrated lessened culpability of youth and
    greater prospects for reform, the Roper Court refused to embrace scientifically
    unsupported but politically popular age-aggravation trope. See id. at 573. Under
    the United States Constitution as interpreted by the Supreme Court, there was
    no constitutional space for the age-aggravation theory in applying the death
    penalty. See id.
    For juveniles who committed homicidal crimes, the Supreme Court drew
    a line at the age of eighteen for application of the categorical ban on execution.
    Id. at 574. The Roper Court recognized that the drawing of a bright line had
    arbitrary features. Id. (noting that line-drawing is subject to objections). The
    Roper Court noted, “The qualities that distinguish juveniles from adults do not
    disappear when an individual turns 18.” Id. Yet, according to Roper, “a line must
    26
    be drawn.” Id. Roper declared that the categorical line for purposes of
    categorically prohibiting the death penalty was drawn at age eighteen because of
    its social acceptance as the dividing line between childhood and adulthood. Id.
    Nothing in Roper, however, suggests that other lines could not be drawn in other
    contexts involving juveniles.
    3. Graham v. Florida. Indeed, Graham demonstrated the notion that there
    were further lines to be drawn. 
    560 U.S. 48
    . In Graham, the question was
    whether a juvenile offender under the age of eighteen could be sentenced to
    mandatory death in prison, typically referred to as life without possibility of
    parole, for nonhomicidal crimes. The Supreme Court, drawing another
    categorical line, said no. 
    Id.
     at 74–75.
    The reasoning of the decision in Graham hewed closely to that of Roper.
    The Graham Court noted that developments “in psychology and brain science
    continue to show fundamental differences between juvenile and adult minds[,]
    [f]or example, parts of the brain involved in behavior control.” 
    Id. at 68
    . It cited
    amicus briefs filed by the American Medical Association and the American
    Psychological Association for the proposition that behavior control continues to
    mature through adolescence. 
    Id.
    The Graham Court recognized the goals of retribution, deterrence,
    incapacitation, and rehabilitation. 
    Id.
     at 71–72. While recognizing the legitimacy
    of retribution in criminal sentencing, the Court observed that the personal
    culpability of a juvenile offender was not as strong as it was with an adult. 
    Id. at 74
    . Further, deterrence was limited because of the limited moral responsibility
    27
    of the offender. 
    Id. at 72
    . With respect to incapacitation, the Graham Court noted
    it was difficult even for trained “psychologists to differentiate between the
    juvenile offender whose crime reflects unfortunate yet transient immaturity, and
    the rare juvenile offender whose crime reflects irreparable corruption.” 
    Id. at 73
    (quoting Roper, 
    543 U.S. at 573
    ). Finally, the Graham Court noted the similarity
    between the death penalty and life without possibility of parole. Id. at 78.
    Although life in prison without the possibility of parole was different than death,
    the Graham Court recognized that both “share some characteristics” in that both
    “alter[] the offender’s life by a forfeiture that is irrevocable,” and “deprive[] the
    convict of the most basic liberties without giving hope of restoration.” Id. at 69–
    70.
    The Graham Court further noted that a sentence of life without possibility
    of parole “forswears altogether the rehabilitative ideal.” Id. at 74. While the Court
    recognized that the state was “not required to guarantee eventual freedom to a
    juvenile offender,” it must give the offender “some meaningful opportunity to
    obtain release based on demonstrated maturity and rehabilitation.” Id. at 75. In
    adopting a categorical rule and rejecting a case-by-case analysis, the Graham
    Court noted that it was difficult to distinguish with accuracy “the few incorrigible
    juvenile offenders” from the many who are capable of change. Id. at 77.
    4. Miller v. Alabama. Finally, the Supreme Court in Miller v. Alabama,
    considered whether juveniles under the age of eighteen who committed homicidal
    crimes could be sentenced to life without possibility of parole. 
    567 U.S. 460
    , 465
    (2012). Miller recognized that the observations in Graham were made in the
    28
    context of nonhomicidal crimes. 
    Id. at 473
    . Yet, it emphasized that “none of what
    [Graham] said about children—about their distinctive (and transitory) mental
    traits and environmental vulnerabilities—is crime-specific.”1 
    Id.
     Here, the
    Supreme Court clearly broke from its “death is different” analysis in favor of a
    “children are different” approach, see 
    id.
     at 472–74, and stated that “imposition
    of a State’s most severe penalties on juvenile offenders cannot proceed as though
    they were not children.” 
    Id. at 474
    .
    Again, the Miller Court emphasized that juvenile life sentences were
    “analogous to capital punishment.” 
    Id. at 475
     (quoting Graham, 560 U.S. at 89
    (Roberts, C.J., concurring in the judgment)). In imposing the harshest sentences
    like life without possibility of parole, Miller stressed the importance of not
    excluding “the possibility of compassionate or mitigating factors” from
    consideration. Id. (quoting Woodson v. North Carolina, 
    428 U.S. 280
    , 304 (1976)).
    Miller pointed out that Alabama’s mandatory sentencing scheme “poses too great
    a risk of disproportionate punishment.” Id. at 479. Although Miller did not
    foreclose the possibility of a life-without-possibility-of-parole sentence for
    juveniles in homicide cases, it required the state “to take into account how
    children are different, and how those differences counsel against irrevocably
    sentencing them to a lifetime in prison.” Id. at 480.
    1In  Miller, the Supreme Court repeated the observations in Graham that the science and
    social science findings related to “transient rashness, proclivity for risk, and inability to assess
    consequences[] both lessened a child’s ‘moral culpability’ and enhanced the prospect that, as the
    years go by and neurological development occurs, his ‘ “deficiencies will be reformed.” ’ ” Miller,
    
    567 U.S. at 472
     (quoting Graham, 560 U.S. at 68).
    29
    An important aspect of Miller is the reliance on Woodson v. North Carolina,
    
    428 U.S. 280
     (1976). Woodson, of course, stands for the proposition that before
    the death penalty may be imposed, the court must conduct an individualized
    inquiry on a case-by-case basis to determine whether the defendant is
    sufficiently culpable to merit the death penalty. 
    Id. at 304
    ; see also Lockett v.
    Ohio, 
    438 U.S. 586
    , 605 (1978) (“[A]n individualized decision is essential in
    capital cases.”).
    B. Iowa Precedent Regarding Juvenile Sentencing. Although the
    language in article I, section 17 of the Iowa Constitution is similar to that of the
    Eighth Amendment to the United States Constitution, we, of course, are not
    bound to follow the approach of the United States Supreme Court in its
    interpretation of parallel Eighth Amendment provisions, and instead are free to
    develop our own independent approach. E.g. State v. Ochoa, 
    792 N.W.2d 260
    ,
    264 (Iowa 2010). See generally Mark Denniston & Christoffer Binning, The Role
    of State Constitutionalism in Determining Juvenile Life Sentences, 17 Geo. J.L. &
    Pub. Pol’y 599 (2019) (identifying and discussing the post-Miller implementation
    trend of criminal sentences for juvenile offenders and concluding that, due to a
    lack of guidance, states resolve issues in vastly different ways). That said, we
    look to cases of the Supreme Court, and indeed any court, for whatever
    persuasive reasoning they might provide. Ochoa, 792 N.W.2d at 264–65.
    We have embraced the Supreme Court’s rationale in Roper, Graham, and
    Miller and further extended application of the role of neuroscience and social
    psychology in the considering whether certain punishments of juveniles under
    30
    the age of eighteen constitutes cruel and unusual punishment under the Iowa
    Constitution. See, e.g., State v. Sweet, 
    879 N.W.2d 811
    , 839 (Iowa 2016) (holding
    under article I, section 17 of the Iowa Constitution, juvenile offenders may not
    be sentenced to life without possibility of parole); State v. Null, 
    836 N.W.2d 41
    ,
    71 (Iowa 2013) (holding that lengthy sentence imposed on juvenile offenders
    triggers Miller-type protections); State v. Pearson, 
    836 N.W.2d 88
    , 96 (Iowa 2013)
    (holding that consecutive sentences resulting in lengthy imprisonment triggers
    Miller-Null-type protections); State v. Ragland, 
    836 N.W.2d 107
    , 118–21 (Iowa
    2013) (holding that the Governor’s commuted sentence amounts to mandatory
    life without parole and was unconstitutional under Miller).
    In State v. Ragland, we considered whether the Governor’s commuting of
    a mandatory life without possibility of parole for a juvenile offender who
    committed felony murder to sixty years mandatory imprisonment was
    constitutional under article I, section 17 of the Iowa Constitution. Ragland, 836
    N.W.2d at 118–19. We concluded that it was not. Id. at 121 (holding that for all
    practical purposes, the same motivation in Miller applies to the commuted
    sentence since it is the practical equivalent to life without parole).
    In State v. Null, after recognizing the fundamental differences between
    juveniles and adults as illustrated by Miller, we held that a cumulative
    mandatory prison term of fifty-two and a half years for second-degree murder
    and first-degree robbery was contrary to the Cruel and Unusual Punishment
    Clause of the United States and Iowa Constitutions. Null, 836 N.W.2d at 70–73.
    After extensively canvassing the body of science related to juvenile immaturity,
    31
    we concluded that the teaching of Miller about children being different was fully
    applicable and that Null was entitled to an individualized sentencing hearing to
    determine the question of parole eligibility. Id. at 70. Although not a life-without-
    possibility-of-parole sentence, we stated that the opportunity for geriatric release
    “does not provide a ‘meaningful opportunity’ to demonstrate the ‘maturity and
    rehabilitation’ required to obtain release and reenter society as required by
    Graham.” Id. at 71 (quoting Graham, 560 U.S. at 75).
    We considered lengthy prison terms for nonhomicidal crime in State v.
    Pearson, 
    836 N.W.2d 88
    , and State v. Lyle, 
    854 N.W.2d 378
     (Iowa 2014). In
    Pearson, we considered a case where a juvenile defendant was convicted of two
    counts of first-degree robbery and two counts of first-degree burglary in
    connection with a crime spree. 836 N.W.2d at 89. The defendant was sentenced
    to thirty-five years in prison without the possibility of parole. Id. We held that
    the teaching of Miller—namely, the need for an individualized hearing before a
    lengthy sentence is imposed on a juvenile offender—applied in a case where a
    thirty-five-year mandatory sentence was imposed for the crimes of robbery and
    burglary. Id. at 91, 96.
    Similarly, in Lyle, we considered a seven-year mandatory sentence of a
    juvenile arising out of a second-degree robbery conviction. 854 N.W.2d at 381.
    We noted, among other things, that “scientific data and the opinions of medical
    experts provide a compelling and increasingly ineluctable case that from a
    neurodevelopment standpoint, juvenile culpability does not rise to the adult-like
    standard.” Id. at 398. We concluded that sentencing to a statutory mandatory
    32
    minimum without a hearing to consider the mitigating factors of youth did not
    adequately serve legitimate penological objectives in light of the child’s
    categorically diminished culpability. Id. at 399.
    Our next foray into the field was State v. Sweet, 
    879 N.W.2d 811
    . In Sweet,
    we considered whether juvenile offenders could be sentenced to life in prison
    without possibility of parole for first-degree murder. Id. at 812. We noted that
    using our independent judgment under article I, section 17 of the Iowa
    Constitution, we have applied the principles of the Roper-Graham-Miller trilogy
    “outside the narrow factual confines of those cases, including cases involving
    de facto life sentences, very long sentences, and relatively short sentences.” Id.
    at 834.
    Further, we repeated that it was extremely difficult for even a trained
    psychologist to determine the small percentage of juvenile offenders who were
    “irreparably corrupt.” Id. at 834. We noted that the district court could not decide
    in any principled way which adolescents were those very few who might later
    prove to be irreparably depraved. Id. at 837. We cited Montgomery v. Louisiana,
    
    577 U.S. 190
     (2016), for the proposition that a life-without-possibility-of-parole
    sentence should be available to a juvenile offender only in the rarest of cases. Id.
    at 834. We declined to ask our district courts to do what trained professionals
    with years of clinical experience declined to do, namely, identify the rarest of
    cases where a youth could be shown to be irreparably corrupt, thereby
    supporting a life-without-possibility-of-parole sentence. Id. at 839. Ultimately,
    33
    we held that life-without-possibility-of-parole sentences were categorically
    barred for juveniles. Id.
    IV. Post-Roper/Graham/Miller Authorities Applying Developments in
    Neuroscience and Psychology to Sentencing of Defendants Beyond Age
    Eighteen.
    A. Cases Declining to Extend Analysis. There are a number of federal
    and state court cases that have declined to extend the Miller principles where a
    criminal defendant was over the age of eighteen at the time of the crime. See,
    e.g., Wright v. United States, 
    902 F.3d 868
    , 871–72 (8th Cir. 2018); United States
    v. Williston, 
    862 F.3d 1023
    , 1039–40 (10th Cir. 2017); United States v. Marshall,
    
    736 F.3d 492
    , 500 (6th Cir. 2013); Burgie v. State, 
    575 S.W.3d 127
    , 128–29 (Ark.
    2019); State v. Allen, 
    958 A.2d 1214
    , 1233–36 (Conn. 2008).
    At least some of the cases that have denied relief, however, leave the door
    open to as-applied challenges to harsh sentences by young adults on cruel and
    unusual punishment grounds. For instance, in People v. Harris, the Illinois
    Supreme Court declined to extend the categorical prohibition of Roper to a
    seventy-six-year sentence to a young adult who was eighteen years old at the
    time of the crime. 
    120 N.E.3d 900
    , 912 (Ill. 2018). While the court rejected the
    categorical change, the court declined to rule on the question of whether the
    sentence might be cruel and unusual as applied. 
    Id.
     at 912–14.
    B. Cases Considering Roper/Graham/Miller Principles Beyond the
    Age of Eighteen.
    1. Commonwealth v. Bredhold. In Commonwealth v. Bredhold, a Kentucky
    circuit court considered the potential application of the death penalty to a
    34
    defendant who was eighteen years and five months old at the time of the murder
    and robbery. No. 14–CR–161, 
    2017 WL 8792559
    , at *1 (Ky. Cir. Ct. Aug. 1, 2017).
    Notably, the judge presiding in Bredhold had heard testimony from a nationally
    known expert, Dr. Laurence Steinberg, regarding the differences between
    adolescents under the age of eighteen and young adults aged eighteen to twenty-
    one in a companion case.2 
    Id.
     According to the Bredhold court, Steinberg testified
    that “if a different version of Roper were heard today, knowing what we know
    now, one could’ve made the very same arguments about eighteen (18), nineteen
    (19), and twenty (20) year olds that were made about sixteen (16) and seventeen
    (17) year olds in Roper.” 
    Id.
    The Bredhold court concluded that there was a growing consensus against
    the death penalty for persons under age twenty-one. Id. at *3. Further, the
    Bredhold court concluded that individuals in their late teens and early twenties
    were less mature than older adults and more likely to engage in behavior that
    underestimates risks and promotes “sensation-seeking.” Id. at *4. The Bredhold
    court further noted that young adults are less able to control their impulses and
    consider the future consequences of their acts. Id. In addition, the Bredhold court
    noted that cognitive abilities mature more rapidly than emotional abilities,
    including the ability to exercise control, to properly consider the risks and
    rewards of alternative courses of action, and to resist coercive pressure from
    others. Id. According to the Bredhold court, the applicable research as well as
    2There are some characteristics with death sentences that are shared by other sentences.
    Commonwealth v. Diaz, No. 15–CR–584–001 (Ky. Cir. Ct. Sept. 6, 2017).
    35
    the individual assessment “support the exclusion of the death penalty for this
    Defendant.” Id. at *7.
    The circuit court ruling in Bredhold, however, was short lived. The
    Kentucky Supreme Court vacated the ruling, noting that the defendant had not
    yet been sentenced and, as a result, did not have standing to support a
    constitutional challenge. See Commonwealth v. Bredhold, 
    599 S.W.3d 409
    , 417–
    18 (Ky. 2020).
    Even so, as the Bredhold circuit court noted, the conclusions of an expert
    who made an individualized assessment of the defendant, “are still relevant.”
    Bredhold, 
    2017 WL 8792559
    , at *7. The expert reported that the defendant
    operated “at a level at least four years below that of his peers.” 
    Id.
     According to
    the circuit court, the findings of the expert “further support the exclusion of the
    death penalty” for the defendant. 
    Id.
     Bredhold, of course, is a death penalty case,
    but it extends and applies the science described in Roper to a case involving a
    criminal defendant above the age of eighteen.
    2. State v. Norris. A New Jersey appellate court considered the application
    of Miller in a case involving a twenty-one-year-old defendant in State v. Norris,
    No. A–3008–15T4, 
    2017 WL 2062145
    , at *5 (N.J. Super. Ct. App. Div. May 15,
    2017) (per curiam). The New Jersey appellate court in a short per curiam opinion
    did not explicitly state that the defendant was entitled to the same consideration
    as a juvenile offender, but suggested that Miller factors should be considered
    when the trial court considers a sentence for a lengthy term of incarceration. 
    Id.
    (“[T]he real life consequences of a consecutive, extended-term sentence should
    36
    be considered, particularly under circumstances such as these, where on the
    attempted murder charge the most serious aggravating factors had been
    eliminated and the two that remained were somewhat ubiquitous.”).
    3. People v. House. An intermediate Illinois appellate court considered the
    applicability of developments in brain science to a nineteen-year-old defendant
    in People v. House, 
    72 N.E.3d 357
    , 384 (Ill. App. Ct. 2015), appeal denied,
    judgment vacated, 
    111 N.E.3d 940
     (Ill. 2018). That case involved a question of
    the validity of a life-without-possibility-of-parole sentence imposed on a
    nineteen-year-old defendant convicted of multiple murders. Id. at 383. The court
    reasoned that while the defendant was not a juvenile at the time of the crime,
    his “young age of 19 is relevant in consideration.” Id. at 384. Under the specific
    facts of the case, the court questioned the propriety of mandatory natural life for
    a nineteen-year-old under the theory of accountability. Id. at 385. Additionally,
    the court recognized the continuing brain development in adolescents, id., and
    noted that legal scholars had observed that “the United States Supreme Court is
    moving rather quickly towards abolishing life without parole sentences for
    juvenile offenders entirely.” Id. at 386 (quoting Maureen Dowling, Note, Juvenile
    Sentencing in Illinois: Addressing the Supreme Court Trend Away from Harsh
    Punishments for Juvenile Offenders, 
    35 N. Ill. U. L. Rev. 611
    , 619 (2015)). Most
    importantly, the court argued that while Roper delineated the division between
    juvenile and adult offenders at the age of eighteen, it did not believe that “this
    demarcation has created a bright line rule.” Id. at 386. Instead, it believed such
    division is “somewhat arbitrary.” Id. at 387. Accordingly, the court argued that
    37
    there was a need to expand juvenile sentencing provisions for young adult
    offenders. Id.
    The House holding, however, was vacated by the Illinois Supreme Court,
    
    111 N.E.3d 940
    , with instructions to the appellate court to consider the recent
    holding of the Illinois Supreme Court in Harris, 
    120 N.E.3d 900
    . In Harris, the
    Illinois Supreme Court held that an aggregate sentence of seventy-six years in
    prison upon an eighteen-year-old defendant did not violate the cruel and
    unusual punishment provision of Illinois’s constitution where the defendant only
    raised a facial challenge to the sentence. Id. at 845. The Illinois Supreme Court
    refused to extend Miller, which it regarded as establishing a categorical rule, to
    persons over the age of eighteen. Id. at 846–47. The Harris court emphasized,
    however, that the defendant did not claim the sentence as applied to him was
    cruel and unusual. Id. at 847.
    4. United States v. Cruz. A federal district court approached the question
    of the application of science to the sentencing of a defendant when he was
    eighteen years and twenty weeks old. Cruz v. United States, No. 11–CV–787
    (JCH), 
    2018 WL 1541898
    , at *1 (D. Conn. Mar. 29, 2018), vacated and
    remanded, 826 F. App’x 49 (2d Cir. 2020). In that case, Cruz had been
    incarcerated for many years and was bringing his claim that the life-without-
    possibility-of-parole sentence amounted to cruel and unusual punishment. 
    Id.
    at *1–2.
    The Cruz court considered whether Supreme Court precedent barred the
    district court from consideration of application of the Miller principles to the
    38
    defendant. Id. at *6. According to the Cruz court, Miller said nothing about how
    the Eighth Amendment would apply to mandatory life without possibility for
    parole for those over the age of eighteen. Id. at *15 (stating that the state failed
    to recognize that there were “different kinds of lines” and taking for example that
    the Supreme Court expanded the protection of death penalty sentences for
    underage offenders from sixteen to eighteen through a series of cases from
    Thompson, 
    487 U.S. 815
    , to Stanford, 
    492 U.S. 361
    , and reasoning that,
    similarly, Roper, Graham, and Miller protected offenders that fall under the line
    while remaining silent as to offenders that fall above the line). As a result, Miller
    did not preclude the district court from considering the relevance of science to a
    cruel-and-unusual-punishment claim where the defendant was eighteen years
    old. Id. at *16.
    Dr. Steinberg, an expert on juvenile brain development, testified
    extensively at trial. Dr. Steinberg testified that early adolescence as occurring
    between the ages of ten and thirteen, middle adolescence between the ages of
    fourteen and seventeen, and late adolescence between the ages of eighteen and
    twenty-one. Cruz, 
    2018 WL 1541898
    , at *23. Specifically, late adolescents “still
    show problems with impulse control and self-regulation and heightened
    sensation-seeking, which would make them in those respects more similar to
    somewhat younger people than to older people.” 
    Id.
     Therefore, scientific evidence
    revealed that late adolescents displayed similar characteristics of immaturity
    and impulsivity as juveniles under eighteen. 
    Id.
     Yet, people in late adolescence
    were still more capable of change than adults. Id. at *24.
    39
    Additionally, Dr. Steinberg testified that at the time when Roper was
    decided, little research focused on the brain development of late adolescence or
    young adulthood, so when Roper drew the line at the age of eighteen in 2005,
    scientific record was not available to the United States Supreme Court as it is
    today. Cruz, 
    2018 WL 1541898
    , at *25. Based on the evidence and the body of
    research, the district court concluded that Miller-type principles should be
    extended to persons over the age of eighteen. Id. at *25.
    But the United States Court of Appeals for the Second Circuit reversed.
    See Cruz v. United States, 826 F. App’x 49, 52 (2d Cir. 2020). The Second Circuit
    held that persons who committed offenses when over the age of eighteen were
    not entitled to Miller-type protections, and insisted that Miller embraced the age
    of eighteen as a substantive cut-off date for making similar claims. Id.
    5. United States v. C.R. In C.R., United States District Court Judge Jack
    Weinstein wrote a lengthy opinion considering the validity of a mandatory five-
    year prison sentence on a nineteen-year-old convicted of possession of child
    pornography. 
    792 F. Supp. 2d 343
    , 347 (E.D.N.Y. 2011), vacated by United
    States v. Reingold, 
    731 F.3d 204
     (2d Cir. 2013). Judge Weinstein canvassed the
    science related to the development of juveniles into young adults, and concluded
    that young brains are still developing after the age of eighteen and that their
    culpability was therefore reduced. Id. at 490. He concluded under the facts of
    the case that the imposition of a five-year minimum prison sentence on a
    nineteen-year-old defendant would amount to cruel and unusual punishment.
    Id. at 510.
    40
    V. Overview of the Science Regarding Harsh Sentences for Young
    Adults.
    Roper, of course, was decided in 2005. 
    543 U.S. 551
    . Even in Roper,
    however, the Supreme Court recognized that the juvenile brain development that
    impacted the culpability of criminal defendants did not end at age eighteen but
    extended beyond that date. 
    Id. at 574
    .
    Since then, neuroscience involving adolescents has continued to
    accumulate. Post-Roper studies reinforce the notion that impulsivity and neural
    plasticity are characteristic of young adults. Madison Ard, Note, Coming of Age:
    Modern Neuroscience and the Expansion of Juvenile Sentencing Protections, 
    72 Ala. L. Rev. 511
    , 520–21 (2020). Research has confirmed that the brain
    continues to mature beyond the age of eighteen. See, e.g., Kathryn L. Mills et al.,
    Structural Brain Development Between Childhood and Adulthood: Convergence
    Across Four Longitudinal Samples, 141 Neuroimage 273, 276 (2016); Marc D.
    Rudolph et al., At Risk of Being Risky: The Relationship Between “Brain Age”
    Under Emotional States and Risk Preference, 24 Developmental Cognitive
    Neuroscience 93, 102–03 (2017); Christian K. Tamnes et al., Development of the
    Cerebral Cortex Across Adolescence: A Multisample Study of Inter-Related
    Longitudinal Changes in Cortical Volume, Surface Area, and Thickness, 71 J.
    Neuroscience 3402, 3410 (2017). And social psychology continues to show the
    immaturity of young adults beyond the age of eighteen. See, e.g., Alexandra O.
    Cohen et al., When Is an Adolescent an Adult? Assessing Cognitive Control in
    Emotional and Nonemotional Contexts, 27 Psychological Sci. 549, 550, 559–60
    (2016); Kathryn Monahan et al., Juvenile Justice Policy and Practice: A
    41
    Developmental Perspective, 44 Crime & Just. 577, 582 (2015). As summarized
    by one commentator, “[E]ighteen-to twenty-one-year-olds [are] more similar to
    ten- to seventeen-year-olds on indices of psychosocial maturity than they [are]
    to adults twenty-six years of age and older.” Andrew Michaels, A Decent Proposal:
    Exempting Eighteen- to Twenty-Year-Olds from the Death Penalty, 
    40 N.Y.U. Rev. L. & Soc. Change 139
    , 163 (2016) [hereinafter Michaels].
    In light of the evolving science, there have been suggestions in scholarly
    literature regarding how best to treat young offenders who fall within the aged
    eighteen to twenty-one or eighteen to twenty-five category. Some scholars have
    cogently suggested simply moving some of the categorical goal posts, just like
    the Supreme Court did when it increased the categorical age for prohibition of
    the death penalty from sixteen in Thompson to eighteen in Roper. See John H.
    Blume et al., Death by Numbers: Why Evolving Standards Compel Extending
    Roper’s Categorical Ban Against Executing Juveniles from Eighteen to Twenty-
    One, 
    98 Tex. L. Rev. 921
    , 950 (2020); Carly Loomis-Gustafson, Student Article,
    Adjusting the Bright-Line Age of Accountability within the Criminal Justice System:
    Raising the Age of Majority to Age 21 Based on the Conclusions of Scientific
    Studies Regarding Neurological Development and Culpability, 
    55 Duq. L. Rev. 221
    , 237 (2017); Michaels, 
    40 N.Y.U. Rev. L. & Soc. Change 139
    . These scholars
    urge that the categorical judgment that the death penalty cannot be applied to
    children under the age of eighteen should be raised to age twenty-one or twenty-
    five. In the context of Iowa law, where life without possibility of parole is the
    42
    harshest sanction available, the implication is that this sentence should be
    categorically barred for young adults as well as those under the age of eighteen.
    Other authorities have rejected a per se bar on severe sentences such as
    life without possibility of parole for persons over the age of eighteen, but have
    instead argued that the appropriate way to integrate the science into the
    sentencing process is through an individualized hearing. See William W. Berry
    III, Eighth Amendment Presumptive Penumbras (and Juvenile Offenders), 
    106 Iowa L. Rev. 1
    , 42 (2020). One scholar has suggested that in such an
    individualized hearing, the state would carry the burden of demonstrating the
    need for a life-without-possibility-of-parole sentence. 
    Id.
     Under such a regime, it
    might be difficult to apply a life-without-possibility-of-parole sentence to a
    nonhomicidal crime of a young adult. 
    Id.
    Three leading scholars—Elizabeth S. Scott, Richard J. Bonnie, and
    Laurence Steinberg—wrote a 2016 article considering the question of proper
    treatment of young adults for purposes of applying cruel and unusual
    punishment law. See Elizabeth S. Scott et al., Young Adulthood as a Transitional
    Legal Category: Science, Social Change, and Justice Policy, 
    85 Fordham L. Rev. 641
     (2016) [hereinafter Scott]. In this somewhat dated review of scholarship, the
    authors recognize that it was time to reconsider the law’s approach to young
    adult offenders in light of recent scientific research. Id. at 643. The authors
    caution that the research does not establish that individuals aged eighteen
    through twenty are not indistinguishable from children under the age of
    eighteen. Id. Instead, according to the authors, the young adult years can be best
    43
    understood as a transition stage between adolescence and mature adulthood.
    Id. at 644. In short, the authors reject a binary approach to childhood and
    adulthood. Id. They do not advocate simply extending the categorical goal posts
    of Roper and its progeny to persons under the age of twenty-one or twenty-five.
    The authors caution is based, at least in part, on the limitations in the
    psychological studies of young adults. First, they note that the studies showing
    emotional immaturity are somewhat task dependent. Id. at 648–50. Second, the
    studies of peer pressure for the older age group are equivocal. Id. Third,
    psychological maturity varies at given ages considerably. Id. Finally, age
    differences in psychological functioning in young adulthood seems to vary as a
    function of context. Id. With respect to brain development studies, the authors
    observe that the research has not yet significantly informed our understanding
    of the characteristics necessary for the formation of social policy. Id. at 652.
    Yet, the authors conclude that the research, though not conclusive, shows
    young adults may be “driven by tendencies toward impulsivity and risk-taking
    that characterize much of the criminal activity of juveniles.” Id. at 656–57. Even
    for violent offenses, the authors suggest that the offender’s relative youth should
    be considered in sentencing. Id. at 661. They assert that the evidence may
    support a presumption that mandatory minimum sentencing regimes should
    exclude young adult offenders. Id. at 662; see also William W. Berry III,
    Individualized Sentencing, 
    76 Wash. & Lee L. Rev. 13
     (2019) [hereinafter Berry
    III, Individualized Sentencing] (urging individualized sentencing for youth over
    the age of eighteen); Josh Gupta-Kagan, The Intersection Between Young Adult
    44
    Sentencing and Mass Incarceration, 
    2018 Wis. L. Rev. 669
    , 714 (2018)
    (recommending youth be considered a separate category for cruel and unusual
    punishment proportionality analysis).
    VI. Discussion.
    A. Introduction. This case involves whether the developments in
    neuroscience and social science undermines a mandatory sentence of life
    without possibility of parole for an eighteen-year-old charged with homicide
    under the cruel and unusual punishment clause of article I, section 17 of the
    Iowa Constitution. There are two questions presented. The first question is
    whether the categorical rule in Sweet, namely, that juvenile offenders under the
    age of eighteen cannot be sentenced to life without possibility of parole, should
    be extended to cover the defendant here who committed homicide when he was
    just over eighteen years of age. If the answer to this question is no, a second
    distinctly different question arises, namely, whether a defendant is entitled to an
    individualized Miller-type hearing on the question of whether life in prison
    without possibility of parole may be constitutionally applied given the maturity
    of the defendant.
    B. Categorical Ban on Life Without Parole to Defendants Who Commit
    Crimes When over the Age of Eighteen. In Sweet, we categorically held that a
    child who commits a crime while under the age of eighteen cannot be sentenced
    to life without possibility of parole. 879 N.W.2d at 839. The defendant here
    argues that the categorical rule in Sweet should be extended to a defendant who
    is just over the age of eighteen when the crime is committed. The defendant
    45
    argues that the age of eighteen should not be regarded as a “bright line” that
    excludes consideration of the mitigating features of youth for young adults aged
    eighteen and over. The State responds that the language in Sweet stating that
    the relief applied to persons eighteen years of age was designed as a “bright line”
    that should not be altered in this case.
    Drawing the line at age eighteen for the categorical judgment in Sweet was
    not based on the notion that the mitigating factors of youth explored in those
    cases have no application to sentences of adolescents beyond the age of eighteen.
    Instead, the line has been drawn to support the categorical judgment that life
    without possibility of parole could never be imposed on any juvenile. See id. at
    835–39. The risk of disproportionate punishment of youth under the age of
    eighteen through application of mandatory adult punishment is so high, and the
    ability to identify incorrigible exceptions so difficult, that an across the board
    judgment prohibition is required.
    The case for a categorical judgment that life without possibility of parole
    could never be imposed weakens after the age of eighteen. It is no doubt true
    that the science has evolved since Roper was decided in 2005 and that the
    judgments made in Roper, and in Sweet have been further reinforced by
    additional research. But as pointed out by Scott, Binnie, and Steinberg in 2016,
    the neurological and social science suggesting mitigating factors involving young
    adults who commit serious crimes is at least somewhat more ambiguous than
    the studies involving children. See generally Scott, 
    85 Fordham L. Rev. 641
    . In
    other words, based on the current science, the potential disproportionality of
    46
    application of adult mandatory sentence of life without possibility of parole to
    persons over eighteen when the crime is committed is sufficiently reduced that
    a categorical ban on the punishment is not required.
    As a result, I would decline the invitation of Dorsey to simply extend the
    categorical rule of Sweet prohibiting life-without-possibility-of-parole sentences
    to young adults like Dorsey at this time. I would not, however, rule out the
    possibility that at some point scientific and other developments may require a
    reexamination of my conclusion.
    C. As-Applied Challenge. In the alternative to a categorical challenge,
    Dorsey suggests we apply a State v. Bruegger-type proportionality test in this
    case that takes into account the mitigating factors of youth. See 
    773 N.W.2d 862
    (Iowa 2009). In Bruegger, we held that under Iowa Rule of Criminal Procedure
    2.24(5)(a), a defendant could raise a challenge to the legality of a sentence at any
    time, including claims that the sentence amounted to cruel and unusual
    punishment. 
    Id. at 884
    . We reviewed a case involving a number of nonexclusive
    factors that contributed to excessive punishment, including the convergence of
    a broadly defined criminal statute, the use of a juvenile adjudication when he
    was twelve to enhance his sentence, and the dramatic increase in his
    punishment resulting from the enhancement. 
    Id. at 885
    . We emphasized in
    Bruegger, however, that no party advocated a standard for interpreting the Iowa
    Constitution differently from its federal counterpart. 
    Id. at 883
    . Nonetheless, we
    emphasized our familiar ability to apply the generally applicable standard in a
    fashion more stringent than the federal caselaw. 
    Id.
    47
    This case, however, is distinguishable from Bruegger in two important
    respects. First, no party in Bruegger presented to us an argument regarding the
    potential application of the evolving neuroscience in the evaluation of the
    defendant’s culpability. In this case, however, Dorsey invites us to consider the
    question of gross proportionality in the context of a life-without-possibility-of-
    parole sentence for a person just over the age of eighteen. Second, Brugger
    involved a term of years, while this case involves the harshest sentence available
    in Iowa—life without possibility of parole. In short, the sum and substance of
    Dorsey’s argument, unlike that in Bruegger, is to ask that this court depart from
    the federal precedent and extend our holdings to young adults over eighteen
    years old.
    I now turn to Dorsey’s alternate argument that he is entitled to an
    individualized hearing on his as-applied challenge under article I, section 17 of
    the Iowa Constitution. Dorsey’s position is consistent with the thread of
    authorities that emphasize the need for an individualized assessment before the
    harshest sentence may be imposed on an offender. For instance, in Atkins, the
    Supreme Court ruled in the death penalty context that an individualized
    assessment of a defendant’s mental capacity is required before the death penalty
    could be imposed. 
    536 U.S. at 317, 321
     (noting that an assessment is required
    to decide if the offender is actually mentally impaired, and that such assessment
    possibly would draw much disagreement, but where the offender meets the
    standard, “death is not a suitable punishment for a mentally retarded
    criminal”). Similarly, in Woodson and Lockett v. Ohio, the Supreme Court held
    48
    that individualized assessments were required for considering mitigation in a
    death penalty case. Woodson, 
    428 U.S. at 304
    ; Lockett, 
    438 U.S. at 605
    .
    It is true, of course, that Atkins, Woodson, and Lockett were death penalty
    cases. But life without possibility of parole is the harshest of penalties in Iowa.
    As   established   earlier,   “[L]ife   without   parole   sentences   share   some
    characteristics with death sentences that are shared by no other sentences.”
    Graham, 560 U.S. at 69. They are “an irrevocable judgment about that person’s
    value and place in society.” Id. at 74. From a practical perspective, “[a] young
    person who knows that he or she has no chance to leave prison before life’s end
    has little incentive to become a responsible individual.” Id. at 79.
    In the life-without-possibility-of-parole case of Miller, the Supreme Court
    emphasized the importance of the Woodson-Lockett individualized assessment
    and suggested that the distinction between the death penalty and noncapital
    cases was not absolute. See Berry III, Individualized Sentencing, 76 Wash. & Lee
    L. Rev. at 62; William W. Berry III, The Mandate of Miller, 
    51 Am. Crim. L. Rev. 327
    , 339 (2014). Although Miller involved a defendant under the age of eighteen,
    the availability of an individualized hearing on proportionality of a young offender
    just over the age of eighteen serves as a protective measure to ensure that only
    the most incorrigible of young defendants receive the harshest penalty.
    In my view, the state must make a showing of incorrigibility before a life-
    without-possibility-of-parole sentence can be imposed on a young adult in light
    of the reduced culpability ordinarily associated with youth. As a result, this
    matter should be remanded for a Miller-type individualized hearing to determine
    49
    whether the State can show that the defendant is incorrigible and therefore has
    the culpability necessary to support a life-without-possibility-of-parole-death-in-
    prison sentence. While an offender under the age of eighteen may be entitled to
    a categorical exclusion from a life-without-possibility-of-parole sentence, I would
    hold that an individual older than eighteen might be subject to life without
    possibility of parole provided that the state can make the necessary showing of
    incorrigibility to support the sentence.
    Because of the confluence of the mitigating factors of youth and the
    harshness of the penalty, I would apply a different version of the gross
    proportionality test than has traditionally been applied under the federal
    caselaw. Instead, in the context of a youthful offender facing life without
    possibility of parole, the state should be required to show that the individual
    offender is so incorrigible that even considering a parole-based release at a later
    date is out of the question. This heightened sense of proportionality is necessary
    because of the potent combination of potential mitigating factors and the
    irreversible and severe nature of the underlying punishment. This extension of
    individualized determinations is a small but necessary evolution of our current
    law.
    VII. Conclusion.
    For the above reasons, I would vacate the sentence and remand the matter
    to the district court for further proceedings consistent with this opinion.
