    IN THE COURT OF APPEALS OF THE STATE OF KANSAS
    RONELL WILLIAMS,
    Appellant,
    v.
    STATE OF KANSAS,
    Appellee.
    SYLLABUS BY THE COURT
    1.
    The Eighth Amendment to the United States Constitution prohibits a mandatory
    sentencing scheme that includes a punishment of life in prison without the possibility of
    parole for a juvenile homicide offender if the sentencing process does not give the
    sentencing court discretion to consider a juvenile offender's youth and individual
    attendant characteristics as part of the sentencing process.
    2.
    The constitutional protections afforded under Miller v. Alabama, 
    567 U.S. 460
    ,
    
    132 S. Ct. 2455
    , 
    183 L. Ed. 2d 407
     (2012), are triggered regardless of whether a
    sentencing scheme is mandatory or discretionary.

    183 L. Ed. 2d 407

    A hard 50 term of years sentence is the functional equivalent to a sentence of life
    without parole for purposes of applying the constitutional protections afforded juvenile
    homicide offenders under Miller v. Alabama, 
    567 U.S. 460

    5.
    In deciding whether imposition of a hard 50 sentence on a juvenile offender
    convicted of premediated first-degree murder is constitutionally disproportionate in
    violation of the Eighth Amendment to the United States Constitution, the sentencing
    court must consider the offender's youth and attendant characteristics, including the
    child's diminished culpability and heightened capacity for change.
    Appeal from Wyandotte District Court; J. DEXTER BURDETTE, judge. Opinion filed October 9,
    2020. Reversed, sentence vacated in part, and case remanded with directions.

    Before STANDRIDGE, P.J., HILL and ATCHESON, JJ.
    STANDRIDGE, J.: Ronell Williams committed a very serious, violent crime when
    he was 14 years old and, as a result, was convicted of two counts of premeditated first-
    degree murder arising from the death of two victims. He is serving two concurrent life
    sentences without the possibility of parole for 50 years (hard 50). Williams will spend at
    least a half century in jail before he is eligible to be considered for release.
    2
    When the sentences originally were imposed, the trial judge did not consider the
    characteristics and circumstances attendant to Williams' age. In the past decade, however,
    the United States Supreme Court sent a clear message in that regard: "children are
    different" when it comes to sentencing, and "youth and its attendant characteristics" must
    be considered at the time a juvenile is sentenced to life imprisonment without the
    possibility of parole. Miller v. Alabama, 
    567 U.S. 460
    , 465, 480, 
    132 S. Ct. 2455
    , 
    183 L. Ed. 2d 407
     (2012). The Supreme Court recognized the mitigating qualities of youth and
    directed that judges in those cases consider a number of factors at sentencing, including
    immaturity and "failure to appreciate risks and consequences"; "family and home
    environment"; family and peer pressures; an "inability to deal with police officers or
    prosecutors" or the juvenile's own attorney; and "the possibility of rehabilitation." 
    567 U.S. at 477-78
    . The Miller Court ultimately held that that the Eighth Amendment to the
    United States Constitution prohibits a mandatory sentencing scheme that includes a
    punishment of life in prison without the possibility of parole for a juvenile offender who
    has been convicted of homicide if the sentencing process does not give the sentencing
    court the discretion to consider a juvenile offender's youth and individual attendant
    characteristics as part of the sentencing process. 
    567 U.S. 489
    .
    Citing Miller and the sentencing court's failure to consider the characteristics and
    circumstances attendant to his age, Williams brings this K.S.A. 60-1507 motion
    challenging his hard 50 sentence as constitutionally disproportionate under the Eighth
    Amendment. In response, the State argues the holding in Miller is inapplicable to the
    facts of this case because Williams' hard 50 sentence is not equivalent to life without
    parole and was imposed under a discretionary sentencing scheme. For the reasons stated
    below, however, we hold (1) the constitutional protections afforded under Miller are
    triggered regardless of whether the sentencing scheme is mandatory or discretionary, (2)
    Williams' hard 50 sentence is the functional equivalent of a sentence of life without
    parole for purposes of the constitutional protections in Miller, and (3) Williams was
    deprived of the constitutional guarantees afforded under Miller because the sentencing
    3
    court failed to fully consider his diminished culpability and heightened capacity for
    change before imposing the hard 50 sentence on him. As a result, we reverse and remand
    the case, with specific directions, for resentencing on the premeditated first-degree
    murder convictions. We also vacate the part of Williams' sentence imposing lifetime
    postrelease supervision.
    FACTS
    Highly summarized, the essential facts presented at trial to support the underlying
    criminal charges against Williams are fairly straightforward. On August 3, 1999,
    Williams and his twin brother, age 14, stole a gun from a residence and walked away
    from the crime. After proceeding about a block, they saw Wilbur Williams in his front
    yard on the way to his mailbox. The brothers forced Wilbur back inside his house where
    they held him and his wife Wilma prisoner while searching the house for items to steal.
    Williams' twin brother left the house to drive the victim's vehicle around to the front of
    the house. While his brother was moving the vehicle, Williams shot and killed Wilbur
    and Wilma. The victims are not related to the brothers.
    The district court authorized the State to prosecute Williams as an adult pursuant
    to K.S.A. 1999 Supp. 38-1636(f)(1), and a jury later convicted Williams of two counts
    premeditated first-degree murder, one count aggravated robbery, and one count
    aggravated burglary. The default sentence for premeditated first-degree murder was life
    without the possibility of parole for 25 years (hard 25). See K.S.A. 1999 Supp. 21-
    4706(c); K.S.A. 1999 Supp. 22-3717(b)(1). The sentence was enhanced to a hard 50
    sentence if the sentencing judge found that one or more aggravating circumstances
    existed and that the aggravators were not outweighed by mitigating circumstances.
    K.S.A. 1999 Supp. 21-4635(c). After hearing the arguments of counsel and the
    statements from individuals in support of Williams and from the victims' family, the
    court found that one or more of the statutory aggravating circumstances existed and that
    4
    the aggravating circumstances were not outweighed by any existing mitigating
    circumstances. For each of the two first-degree murder charges, the district court imposed
    a hard 50 sentence. The court also imposed lifetime postrelease supervision. For the
    aggravated robbery and aggravated burglary convictions, the district court sentenced
    Williams to 59 months and 32 months, respectively. The court ordered all four sentences
    to run concurrently. Our Supreme Court affirmed Williams' convictions and sentences on
    March 19, 2004. State v. Williams, 
    277 Kan. 338
    , 
    85 P.3d 697
     (2004).
    On March 15, 2005, Williams filed his first motion for relief under K.S.A. 60-
    1507. See Williams v. State, No. 99,516, 
    2009 WL 1140260
     (Kan. App. 2009)
    (unpublished opinion). In it, Williams claimed his trial counsel was ineffective for failing
    to request a postinterview report from Dr. Jan Roosa, a clinical psychologist who testified
    on his behalf at trial. Williams argued counsel's deficient performance prejudiced him by
    severely limiting Dr. Roosa's ability to testify fully about his expert opinion. The district
    court held an evidentiary hearing but ultimately denied Williams relief, finding he failed
    to show that, but for counsel's deficient performance, the result of the trial would have
    been different. A panel of our court affirmed. See 
    2009 WL 1140260
    , at *8.
    In 2012, the United States Supreme Court held in Miller, 
    567 U.S. at 489
    , that the
    Eighth Amendment prohibits a mandatory sentencing scheme that includes a punishment
    of life in prison without the possibility of parole for a juvenile offender who has been
    convicted of homicide if the sentencing process does not give the sentencing court the
    discretion to consider a juvenile offender's youth and individual attendant characteristics
    as part of the sentencing process. In 2016, the United States Supreme Court decided
    Montgomery v. Louisiana, 577 U.S. __, 
    136 S. Ct. 718
    , 732, 
    193 L. Ed. 2d 599
     (2016),
    which held that the legal principles announced in Miller are substantive and therefore
    retroactive in cases on collateral review.
    5
    On September 30, 2016, Williams filed a second pro se K.S.A. 60-1507 motion
    claiming the sentencing structure under which his hard 50 sentence was imposed violated
    Miller, which means his sentence is now unconstitutional under the Eighth Amendment.
    Specifically, Williams argued that because his hard 50 sentence is the practical equivalent
    of a life sentence without parole and it was imposed under a mandatory sentencing
    scheme, the constitutional findings in Miller require that his sentence be vacated and the
    case remanded so the court can consider his youth and attendant characteristics before
    resentencing him. The district court did not reach the merits of Williams' argument and
    dismissed the habeas motion as untimely and successive.
    ANALYSIS
    Williams claims the district court erred by summarily denying his motion on
    procedural grounds because he sufficiently established the manifest injustice and
    exceptional circumstances necessary to justify his untimely and successive filing.
    Assuming we find in his favor on this procedural claim of error, Williams asks us to find
    in his favor on the merits of his claims: that his hard 50 sentence must be vacated and the
    matter remanded for a new sentencing hearing with directions for the court to consider
    his youth and its attendant characteristics as set forth in Miller before imposing a new
    sentence. Williams also claims the district court erred by imposing lifetime postrelease
    supervision as part of his sentence for the premeditated first-degree murder convictions.
    We address each of Williams' claims in turn.
    A. Summary dismissal on procedural grounds
    The district court summarily denied Williams' K.S.A. 60-1507 motion on
    procedural grounds, finding the 2016 motion was successive to his 2005 habeas corpus
    motion and untimely filed. See K.S.A. 2019 Supp. 60-1507(c), (f). But Williams argues
    that the Supreme Court's decision in Miller is an intervening change in the law that
    6
    constitutes an exceptional circumstance justifying our consideration of a successive
    motion. Williams also argues that the one-year time limit should be extended by the court
    to prevent a manifest injustice; specifically, that the untimely nature of his motion should
    be excused because Miller—the case providing substantive support for the 60-1507 claim
    that his sentence constitutes cruel and unusual punishment—was not decided until 2012
    and was not given retroactive effect until the Supreme Court decided Montgomery in
    2016.
    1. Exceptional circumstances
    When a district court summarily denies a K.S.A. 60-1507 motion, appellate review
    of that ruling is de novo. See Thuko v. State, 
    310 Kan. 74
    , 80, 
    444 P.3d 927
     (2019). The
    interpretation of statutes and Supreme Court rules involves questions of law reviewable
    de novo. Stewart v. State, 
    310 Kan. 39
    , 43, 
    444 P.3d 955
     (2019).
    A court is not required to entertain successive motions for similar relief on behalf
    of the same prisoner. K.S.A. 2019 Supp. 60-1507(c). Nevertheless, our Supreme Court
    "has decades of caselaw holding that K.S.A. 60-1507's prohibition on successive motions
    is subject to exceptions." Nguyen v. State, 
    309 Kan. 96
    , 107, 
    431 P.3d 862
     (2018). "To
    avoid having a second or successive K.S.A. 60-1507 motion dismissed as an abuse of
    remedy, the movant must establish exceptional circumstances." Beauclair v. State, 
    308 Kan. 284
    , 304, 
    419 P.3d 1180
     (2018). But cf. Nguyen, 309 Kan. at 108 ("[A] plain
    reading of [Supreme Court Rule 183(d) on successive motions] would suggest that a
    district court is permitted to decline to consider a successive motion only 'when . . .
    justice would not be served by reaching the merits of the subsequent motion.'"). See
    Supreme Court Rule 183(d) (2020 Kan. S. Ct. R. 223). "'Exceptional circumstances are
    unusual events or intervening changes in the law that prevented the defendant [from]
    raising the issue in a preceding [K.S.A.] 60-1507 motion.' The burden to make such a
    showing lies with the movant. [Citations omitted.]" Beauclair, 308 Kan. at 304.
    7
    Applying the legal principles set forth in Beauclair to the facts here, we
    necessarily conclude that the Supreme Court's decisions in Miller and Montgomery are
    intervening changes in the law under which Williams can now claim an error affecting
    his constitutional rights and therefore constitute exceptional circumstances justifying our
    consideration of Williams' second K.S.A. 60-1507 motion. See Dunlap v. State, 
    221 Kan. 268
    , 270, 
    559 P.2d 788
     (1977). Given Williams could not have raised a claim that his
    hard 50 sentence was cruel and unusual punishment until 2016—after Montgomery made
    Miller retroactive—we also conclude that justice would be served by reaching the merits
    of the motion, which excludes his successive claim from the requirement in Rule 183(d)
    that the court not consider it. See Rule 183(d) (court may not consider second or
    successive motion for relief by same movant when ground for relief was determined
    adversely to movant on merits in prior motion and when justice would not be served by
    reaching merits of subsequent motion); see also Littlejohn v. State, 
    310 Kan. 439
    , 444-45,
    
    447 P.3d 375
     (2019) (whether justice would be served by reaching merits of successive
    motion is part of statutorily driven analysis of whether exceptional circumstances exist).
    2. Manifest injustice
    The mandate in Williams' direct appeal was issued on April 15, 2004. Williams
    filed his second habeas motion in September 2016, well past the one-year time limit. The
    one-year time limit "may be extended by the court only to prevent a manifest injustice."
    K.S.A. 2019 Supp. 60-1507(f)(2). Effective July 1, 2016, the Legislature amended
    subsection (f)(2) and limited the factors a court may consider when determining whether
    the manifest injustice exception applies to "(1) a movant's reasons for the failure to timely
    file the motion . . . or (2) a movant's claim of actual innocence." White v. State, 
    308 Kan. 491
    , 496, 
    421 P.3d 718
     (2018). We apply the amended statute to Williams because it was
    in effect when he filed his second habeas motion.
    8
    Williams argues his reason for failing to file a timely motion establishes the
    required manifest injustice. The following chronology is relevant to Williams' argument:
     On June 25, 2012, the United States Supreme Court decided Miller, which held
    that mandatory life imprisonment without parole for offenders who committed
    homicide crimes as juveniles violates the Eighth Amendment's prohibition on
    cruel and unusual punishments.
     On June 5, 2015, the Kansas Supreme Court applied Miller to a case on direct
    appeal, holding that mandatory lifetime postrelease supervision for juveniles who
    have committed and are later convicted of aggravated indecent liberties
    categorically constitutes cruel and unusual punishment. See State v. Dull, 
    302 Kan. 32
    , 35, 
    351 P.3d 641
     (2015).
     On January 27, 2016, the United States Supreme Court decided Montgomery,
    which held that Miller applies retroactively on collateral review of a prisoner's
    sentence.
     On September 30, 2016, Williams filed his second K.S.A. 60-1507 motion.
    From this chronology, we can see that Williams filed his second K.S.A. 60-1507
    motion a little over eight months after the United States Supreme Court ruled that the
    holding in Miller applied retroactively and could be raised by a prisoner in a collateral
    attack of his or her sentence. Williams claims his motion must be considered on the
    merits to prevent a manifest injustice because he filed it less than one year after relief on
    his claim became a viable option. We agree and find the facts here present the rare and
    extraordinary circumstances that justify extending the one-year time limit to prevent a
    manifest injustice. See K.S.A. 2019 Supp. 60-1507(f)(2); Beauclair, 308 Kan. at 302
    9
    (Kansas' manifest injustice exception to procedural bar based on untimeliness should
    remain rare and be applied only in the extraordinary case).
    In sum, we conclude that the intervening change in the law as set forth in Miller
    and made retroactive in Montgomery constitutes a manifest injustice and extraordinary
    circumstances to justify the untimely and successive nature of Williams' motion under the
    specific facts presented in this case. Based on our conclusion, we move on to consider the
    merits of Williams' substantive claims for relief.
    B. The constitutionality of Williams' hard 50 sentence under the rule in Miller
    Williams claims his hard 50 sentence violates the Eighth Amendment's prohibition
    on cruel and unusual punishments because it was imposed under a sentencing structure
    that has since been deemed unconstitutional under Miller. To provide the proper context
    for our analysis of Williams' arguments, we start by reviewing the evolution of United
    States Supreme Court caselaw on issues relating to life sentences for juvenile offenders.
    In 1988, the Supreme Court held that the execution of a person under the age of 16
    violated the Eighth Amendment's prohibition against cruel and unusual punishment.
    Thompson v. Oklahoma, 
    487 U.S. 815
    , 838, 
    108 S. Ct. 2687
    , 
    101 L. Ed. 2d 702
     (1988).
    The Court explained that "contemporary standards of decency" inform against executing
    a person who was under 16 years of age at the time of his or her offense. 
    487 U.S. at 823
    .
    In addition to societal standards, the Court also relied on its past cases for the proposition
    that adolescents as a class are less mature and responsible than adults; therefore, less
    culpability should attach to a crime committed by a juvenile than to a comparable crime
    committed by an adult. 
    487 U.S. at 835
    .
    In 1989, the Supreme Court again referred to contemporary "standards of
    decency" but came to a different conclusion in holding that the execution of persons who
    10
    were 16 or 17 years old at the time of their offense did not violate the Eighth
    Amendment's prohibition against cruel and unusual punishment. Stanford v. Kentucky,
    
    492 U.S. 361
    , 380, 
    109 S. Ct. 2969
    , 
    106 L. Ed. 2d 306
     (1989). In support of its
    conclusion, the Stanford Court stated it was not persuaded by evidence that 16- and 17-
    year-old juveniles possess less developed cognitive skills than adults, are less likely to
    fear death, or are less mature and responsible. Accordingly, the Court held juveniles who
    committed crimes when in this narrow age group were as morally blameworthy as adults.
    
    492 U.S. at 377-78
    .
    In 2005, the Supreme Court overruled Stanford and held that the Eighth
    Amendment's prohibition against "cruel and unusual punishments" categorically
    precludes the Court from imposing the death penalty on juveniles who committed the
    offense charged when they were less than 18 years old. Roper v. Simmons, 
    543 U.S. 551
    ,
    578-79, 
    125 S. Ct. 1183
    , 
    161 L. Ed. 2d 1
     (2005). In support of its holding, the Court
    pointed to evidence of a developing consensus among the states of "evolving standards of
    decency" indicating that society had become opposed to the death penalty when the
    offender was under the age of 18. 
    543 U.S. at 561, 564-75
    . The Court found the source of
    this consensus was rooted in the undisputed and long held belief that there are major
    differences between juveniles and adults. The Court found persuasive certain scientific
    studies examining common characteristics of juvenile offenders. From these studies, the
    Court recognized that juveniles typically possess three characteristics that make them
    different than adults and, consequently, less blameworthy: juveniles often are more
    impetuous and reckless, they often are more vulnerable to negative influences and peer
    pressure, and their traits are more transitory and less fixed. 
    543 U.S. at 569-70
    . In light of
    these characteristics, the Court held the usual sentencing justifications for the death
    penalty—retribution and deterrence—did not provide adequate justification for imposing
    the death penalty on juvenile offenders. 
    543 U.S. at 571-72
    . The Court concluded that the
    differences between juveniles and adults "are too marked and well understood to risk
    11
    allowing a youthful person to receive the death penalty despite insufficient culpability."
    
    543 U.S. at 572-73
    .
    In 2010, the Supreme Court extended its reasoning in Roper to overturn the
    sentence of a juvenile offender sentenced to life imprisonment without parole. Graham v.
    Florida, 
    560 U.S. 48
    , 
    130 S. Ct. 2011
    , 
    176 L. Ed. 2d 825
     (2010). Unlike the holding in
    Roper, the Graham Court did not conclude that this punishment was unconstitutional for
    all juvenile offenders. Instead, the Court drew a distinction between juveniles convicted
    of homicide and those convicted of offenses other than homicide. The Court held that a
    sentence of life without parole violates the Eighth Amendment only when imposed on a
    juvenile offender who did not commit homicide. Graham, 560 U.S. at 82. In doing so, the
    Court applied the categorical approach to assess the limits of what constitutes cruel and
    unusual punishment under the Eighth Amendment.
    The Graham Court acknowledged that its cases previously had considered two
    distinct subsets when adopting categorical rules to define Eighth Amendment standards:
    "one considering the nature of the offense, the other considering the characteristics of the
    offender." 560 U.S. at 60.
    "With respect to the nature of the offense, the Court has concluded that capital
    punishment is impermissible for nonhomicide crimes against individuals. In cases turning
    on the characteristics of the offender, the Court has adopted categorical rules prohibiting
    the death penalty for defendants who committed their crimes before the age of 18, or
    whose intellectual functioning is in a low range. [Citations omitted.]" 560 U.S. at 60-61.
    The Graham Court began its categorical Eighth Amendment proportionality
    analysis by looking to "'the evolving standards of decency that mark the progress of a
    maturing society.'" 560 U.S. at 58, 62. In addition to evolving standards of decency, the
    Court held an Eighth Amendment proportionality analysis must also include
    "consideration of the culpability of the offenders at issue in light of their crimes and
    12
    characteristics, along with the severity of the punishment in question. In this inquiry the
    Court also considers whether the challenged sentencing practice serves legitimate
    penological goals." 560 U.S. at 67. The Court reiterated its analysis in Roper that
    juveniles have "lessened culpability" in comparison to adults. 560 U.S. at 68. Noting that
    developments in psychology and brain science continued to show fundamental
    differences between juvenile and adult minds—for example, in parts of the brain
    involved in behavior control—the Court reasoned that transient rashness, proclivity for
    risk, and inability to assess consequences all lessened a child's moral culpability and
    enhanced the prospect that, as the years go by and neurological development occurs, his
    or her deficiencies will be reformed. Graham, 560 U.S. at 67-69. The Court also noted
    that life without parole is an "especially harsh" sentence for a juvenile defendant as it
    condemns the juvenile to a larger percentage of the individual's life in prison than a much
    older individual who receives the same sentence. 560 U.S. at 70.
    The Supreme Court then turned to the "penological justifications" for imposing a
    life without parole sentence on juvenile nonhomicide offenders. 560 U.S. at 71. The
    Court discussed the four common purposes of sentencing schemes: retribution,
    deterrence, incapacitation, and rehabilitation. 560 U.S. at 71-74. It found retribution was
    insufficient as justification for a life sentence without parole because "'[t]he heart of the
    retribution rationale is that a criminal sentence must be directly related to the personal
    culpability of the criminal offender,'" and that "'the case for retribution is not as strong
    with a minor as with an adult.'" 560 U.S. at 71. Deterrence could not justify the sentence
    because the characteristics that make juveniles more likely to make bad decisions also
    make them less likely to consider the possibility of punishment, which is a prerequisite to
    a deterrent effect. Incapacitation could not support the sentence because of the difficulty
    in determining whether a juvenile defendant is incorrigible at the time of sentencing—
    i.e., "'to differentiate between the juvenile offender whose crime reflects unfortunate yet
    transient immaturity, and the rare juvenile offender whose crime reflects irreparable
    corruption.'" 560 U.S. at 72-73. Finally, rehabilitation could not justify the sentence
    13
    because it denies the prisoner the right to "reenter the community [based on] an
    irrevocable judgment about that person's value and place in society." 560 U.S. at 74.
    After considering the especially harsh nature of a sentence of life without parole
    for juvenile offenders, the lack of penological justifications for the sentencing practice,
    and the characteristics of youth outlined in Roper, the Supreme Court considered several
    potential procedural solutions. Graham, 560 U.S. at 68-79. The Court concluded that a
    "categorical rule" was needed to "give[] all juvenile nonhomicide offenders a chance to
    demonstrate maturity and reform," and held that the Eighth Amendment forbids a
    sentence of life without parole for a juvenile offender that did not commit homicide. 560
    U.S. at 68-82. But the Court noted that its holding does not mean that a state is "required
    to guarantee eventual freedom to a juvenile offender convicted of a nonhomicide crime."
    560 U.S. at 79, 82. The Court ultimately held that the Eighth Amendment does not
    prohibit the states from imposing a life sentence on a juvenile nonhomicide offender so
    long as the state provides some meaningful opportunity for release during the offender's
    lifetime based on the offender's demonstrated maturity and rehabilitation, i.e., a
    meaningful possibility of parole. 560 U.S. at 82.
    In 2012—two years after Graham—the Supreme Court applied some of the same
    reasoning to hold that the Eighth Amendment prohibits the punishment of life in prison
    without the possibility of parole for a juvenile offender convicted of homicide under a
    mandatory sentencing scheme. Miller, 
    567 U.S. 489
    . The Court did not impose a
    categorical ban to sentencing a juvenile homicide offender to life in prison without the
    possibility of parole but imposed a requirement that the Court consider a juvenile
    offender's youth and individual attendant characteristics as part of the sentencing process.
    
    567 U.S. at 489
    .
    At issue in Miller was an Eighth Amendment challenge in a consolidated appeal
    involving two 14-year-old offenders who received mandatory sentences of life
    14
    imprisonment without the possibility of parole based on their single murder convictions.
    In both defendants' cases, there was only one possible punishment for the murders: a
    statutorily mandated sentence of life without the possibility of parole. Based on the
    mandatory and lifetime nature of those sentences, the Court determined that the sentences
    implicated "two strands of precedent reflecting [its] concern with proportionate
    punishment." 
    567 U.S. at 470
    .
    The Supreme Court began with the first strand of precedent by reaffirming the
    foundational principle articulated in Roper and Graham: "children are constitutionally
    different from adults for purposes of sentencing [b]ecause juveniles have diminished
    culpability and greater prospects for reform." Miller, 
    567 U.S. at 471
    . The Court
    concluded that the mandatory nature of the sentencing schemes infringe on the
    constitutional principles announced in Roper and Graham because the "laws prohibit a
    sentencing authority from assessing whether the law's harshest term of imprisonment
    proportionately punishes a juvenile offender." Miller, 
    567 U.S. at 474
    .
    With regard to the second strand of precedent that deals with the lifetime nature of
    the punishment, the Court stated that Graham's treatment of juvenile life without parole
    sentences as analogous to capital punishment requires individualized sentencing where
    the judge or jury can assess any mitigating factors—including the mitigating qualities of
    youth—to ensure that the most severe penalty "is reserved only for the most culpable
    defendants committing the most serious offenses." 
    567 U.S. at 475-76
    . Relying on the
    analysis in Graham, the Supreme Court concluded that the flaw with a mandatory life
    sentence without parole was that it "preclude[s] a sentencer from taking [into] account
    . . . an offender's age and the wealth of characteristics and circumstances attendant to it,"
    and "disregards the possibility of rehabilitation even when the circumstances most
    suggest it." Miller, 
    567 U.S. at 476-78
    .
    15
    Dovetailing the two strands of precedent, the Supreme Court ultimately held that
    the Eighth Amendment forbids a sentencing scheme that mandates life in prison without
    the possibility of parole for a juvenile offender who has been convicted of homicide. The
    mitigating qualities of youth and its attendant characteristics, the harsh length of the term
    of imprisonment, and the mandatory nature of the sentencing scheme were key to the
    Court's decision. Unlike Roper and Graham, however, the Court expressly declined to
    impose a categorical ban on sentencing juvenile homicide offenders to life without
    parole. Instead, the Court required "only that a sentencer follow a certain process—
    considering an offender's youth and attendant characteristics—before imposing a
    particular penalty." Miller, 
    567 U.S. at 483
    . So Miller does not prohibit a sentencing
    scheme that includes a punishment of life in prison without the possibility of parole for a
    juvenile offender who has been convicted of homicide so long as the Court considers a
    juvenile offender's youth and individual attendant characteristics as part of the sentencing
    process. 
    567 U.S. at 479-80
    . The Court noted that "sentencing juveniles to this harshest
    possible penalty will be uncommon," because the sentencer must be able to "take into
    account how children are different, and how those differences counsel against irrevocably
    sentencing them to a lifetime in prison." 
    567 U.S. at 479-80
    . And the Court clarified that
    a sentence of life without parole should only be imposed on "the rare juvenile offender
    whose crime reflects irreparable corruption." 
    567 U.S. at 479-80
    .
    Most recently, the Supreme Court decided that the holding in Miller "is retroactive
    to juvenile offenders whose convictions and sentences were final when Miller was
    decided." Montgomery, 136 S. Ct. at 725. The State of Louisiana argued that the rule
    announced in Miller was procedural in nature and therefore not retroactive to juvenile
    offenders whose sentences were final when Miller was decided. But the Court disagreed.
    In its analysis, the Court acknowledged that Miller's holding had both a substantive and a
    procedural component. The Court deemed Miller's substantive holding to be that
    mandatory life without parole is an excessive sentence for children whose crimes reflect
    transient immaturity. But the Court found Miller's requirement that the sentencer consider
    16
    a juvenile offender's youth and attendant characteristics before deciding that life without
    parole is a proportionate sentence was simply an attendant procedural process that was
    necessary to implement the underlying substantive rights under the Eighth Amendment.
    136 S. Ct. at 734-35. The Court stated that "[t]here are instances in which a substantive
    change in the law must be attended by a procedure that enables a prisoner to show that he
    falls within the category of persons whom the law may no longer punish" and the
    required "hearing does not replace but rather gives effect to Miller's substantive holding
    that life without parole is an excessive sentence for children whose crimes reflect
    transient immaturity." 136 S. Ct. at 735. The Court ultimately held "that Miller
    announced a substantive rule of constitutional law" that must be applied retroactively in
    its entirety. 136 S. Ct. at 736.
    Having provided the legal framework for our forthcoming analysis, we turn to the
    merits of Williams' claim that the mandatory hard 50 life sentence imposed on him as a
    juvenile constitutes cruel and unusual punishment under the legal principles announced in
    Miller. Williams sets forth three arguments to support his claim. First, Williams argues
    the constitutional protections afforded under Miller are triggered in this case because his
    hard 50 sentence was imposed under a mandatory sentencing scheme. Second, he argues
    the constitutional protections afforded under Miller are triggered in this case because his
    hard 50 sentence is the functional equivalent of a life without parole sentence. Third,
    Williams argues he was deprived of the constitutional guarantees afforded under Miller
    because the sentencing court failed to fully consider his diminished culpability and
    heightened capacity for change before imposing the hard 50 sentence on him.
    1. The mandatory nature of the hard 50 sentencing scheme
    Williams argues the mandatory nature of the framework under which he was
    sentenced triggers the constitutional protections afforded under Miller. The State
    disagrees arguing that Miller does not apply in this case because the hard 50 sentencing
    17
    framework provided the court with discretion to determine whether the aggravating
    circumstances in Williams' case outweighed any mitigating circumstances. See K.S.A.
    1999 Supp. 21-4635(c) (if sentencing court finds aggravating circumstances are not
    outweighed by any mitigating circumstances, court shall impose hard 50 sentence instead
    of hard 25 sentence). We find it unnecessary to resolve this dispute between the parties
    because, for the reasons stated below, we conclude Miller applies regardless of whether a
    sentencing scheme is mandatory or discretionary.
    The states are split over whether the constitutional protections afforded by Miller
    apply when a juvenile defendant is sentenced under a discretionary sentencing
    framework. There was some hope that the split would be resolved by the United States
    Supreme Court in the Washington D.C. sniper case, Mathena v. Malvo, No. 18-217
    (U.S.), which was argued before the Court on October 16, 2019. But before an opinion
    was issued, Virginia enacted new legislation allowing prisoners serving life sentences
    without parole for crimes committed as juveniles to be eligible for parole after 20 years
    of incarceration. The parties in Malvo stipulated to dismissal of the case, and the Supreme
    Court dismissed the appeal on February 26, 2020. Mathena v. Malvo, __ U.S. __, 
    140 S. Ct. 919
    , 
    206 L. Ed. 2d 250
     (2020). Just over two weeks later, the Court granted certiorari
    in the case of Jones v. Mississippi, No. 18-1259 (U.S.), in which a distinct but related
    issue was presented: whether Miller and Montgomery require the sentencing court to find
    that a juvenile homicide offender is permanently incorrigible before sentencing him or
    her to a sentence of life without parole. 
    140 S. Ct. 1293
     (2020).
    So for now, the states remain divided. A majority of states conclude in published
    opinions that both mandatory and discretionary life sentences for juvenile defendants are
    disproportionate and violate the Eighth Amendment under Miller unless the sentencing
    court considers youth and its attendant characteristics. See Landrum v. State, 
    192 So. 3d 459

    187 Wash. 2d 420
    , 440-44, 
    387 P.3d 650
     (2017). Some of these courts first addressed the
    issue of whether the statutory schemes themselves were constitutionally valid before
    applying the rule in Miller. But regardless of the outcome on that issue, these courts
    ultimately applied the legal principles announced in Miller in cases where the trial court
    had at least some form of sentencing discretion.
    A minority of states conclude in published opinions that Miller offers no
    protection if the sentencing court has even nominal discretion. See Bell v. State, 
    522 S.W.3d 788
    , 789 n.1 (Ark. 2017); Conley v. State, 
    972 N.E.2d 864

    , 920 (S.D. 2017); Jones v.
    Commonwealth, 
    293 Va. 29
    , 40-42, 56-57, 
    795 S.E.2d 705
     (2017).
    After due consideration, we agree with the majority of courts that conclude Miller
    applies to both mandatory and discretionary sentences alike. We see no constitutional
    reason why a juvenile with the mandated sentence of life should receive a Miller hearing,
    19
    while a juvenile with the discretionary life sentence is deprived of the opportunity to have
    his or her "youth and attendant characteristics" taken into account. Both Miller and
    Montgomery support our conclusion.
    Supreme Court precedent now firmly establishes that "children are constitutionally
    different from adults for purposes of sentencing." Miller, 
    567 U.S. at 471
    . Because
    juveniles lack maturity, are more vulnerable to negative influences, and have characters
    that are less well formed, they "are less deserving of the most severe punishments" than
    adults. Graham, 560 U.S. at 68 (citing Roper, 
    543 U.S. at 569
    ). For the same reasons, the
    "penological justifications" for a sentence of life without parole are dramatically
    weakened for juveniles. Miller, 
    567 U.S. at 472-74
    . Applying these principles to a
    sentencing scheme that mandated life without parole, the Miller Court concluded that
    such a scheme "poses too great a risk of disproportionate punishment" to survive
    constitutional scrutiny. 
    567 U.S. at 479
    . The Court continued:
    "[G]iven all we have said in Roper, Graham, and this decision about children's
    diminished culpability and heightened capacity for change, we think appropriate
    occasions for sentencing juveniles to this harshest possible penalty will be uncommon.
    That is especially so because of the great difficulty we noted in Roper and Graham of
    distinguishing at this early age between 'the juvenile offender whose crime reflects
    unfortunate yet transient immaturity, and the rare juvenile offender whose crime reflects
    irreparable corruption.' [Citations omitted.]" Miller, 
    567 U.S. at 479-80
    .
    The Eighth Amendment concerns expressed in Miller exist regardless of whether
    the juvenile in question was sentenced pursuant to a mandatory or discretionary
    sentencing scheme. True, Miller involved two juveniles sentenced to life without parole
    under mandatory sentencing schemes. But the reason the Court invalidated the sentences
    was not because the juveniles were sentenced under a mandatory sentencing scheme but
    because the sentencing court did not have an opportunity to distinguish between juveniles
    whose crimes reflect the transient immaturity of youth from those whose crimes reflect
    20
    irreparable corruption. The reasoning in Miller makes clear that the mere existence of
    discretion, unguided by the factors relevant to the proportionality of sentences for young
    offenders, could not save a juvenile sentence of life without parole. The Eighth
    Amendment permits sentencing a juvenile defendant to life without parole only after a
    court affirmatively considers the juvenile's "diminished culpability and heightened
    capacity for change" and then specifically determines that the juvenile is one of "the rare
    juvenile offender[s] whose crime reflects irreparable corruption." Miller, 
    567 U.S. at
    479-
    80.
    Montgomery later reinforced the rule in Miller. The Court reasoned that the Miller
    rule "rendered life without parole an unconstitutional penalty for 'a class of defendants
    because of their status'—that is, juvenile offenders whose crimes reflect the transient
    immaturity of youth. [Citation omitted.]" Montgomery, 136 S. Ct. at 734. The rule
    recognized in Miller is not about policing formalistic distinctions in state law between
    mandatory and nonmandatory sentences. Instead, it is a constitutional guarantee designed
    to protect individual rights by ensuring that any punishment imposed on a certain "class
    of offenders" (juveniles) satisfies the Eighth Amendment's proportionality requirements.
    See Miller, 
    567 U.S. at 470
    ; see also Roper, 
    543 U.S. at 560
     (noting that Eighth
    Amendment "guarantees individuals the right not to be subjected to excessive
    sanctions"). So when an individual offender falls within the class, the question is not
    whether a sentencing court has an opportunity to make the constitutionally required
    inquiry but whether it seized that opportunity and actually provided the individual with
    the protections that the Constitution requires.
    Based on the constitutional principles articulated by the United States Supreme
    Court in Miller and Montgomery, we hold that the Eighth Amendment prohibits
    sentencing a juvenile to life without parole unless he or she is "the rare juvenile offender
    whose crime reflects irreparable corruption" and that this prohibition applies regardless of
    whether the sentencing scheme is construed as mandatory or discretionary. No matter
    21
    how a state characterizes its sentencing scheme, and no matter what procedures it
    provides, that scheme must "give[] effect to Miller's substantive holding" to be
    constitutional. Montgomery, 136 S. Ct. at 735. So "[e]ven if a court considers a child's
    age before sentencing him or her to a lifetime in prison, that sentence still violates the
    Eighth Amendment for a child whose crime reflects 'unfortunate yet transient
    immaturity.'" 136 S. Ct. at 734 (quoting Miller, 
    567 U.S. at 479
    .)
    2. Does the rule announced in Miller apply to Williams' hard 50 sentence?
    Although acknowledging that the punishment at issue in the Miller case was a
    sentence of life without parole and not a hard 50 sentence, Williams claims the rule in
    Miller is triggered here because his hard 50 sentence is the functional equivalent of a
    sentence of life without parole. The State disagrees, arguing the Miller rule is applicable
    to only those juveniles who are sentenced to life without any opportunity for parole and
    Williams is eligible for parole after serving 50 years in prison. The parties' dispute
    requires us to resolve two separate issues. First, we must decide whether a sentence
    expressed as a term of years, like the hard 50 sentence at issue here, can ever be
    functionally equivalent to a sentence of life without parole for purposes of applying
    Graham and Miller. If so, we must decide whether the lengthy hard 50 sentence imposed
    here is equivalent to life without parole.
    a. Term of years as the functional equivalent of life without parole
    In support of its argument that Miller is inapplicable to any sentence other than
    one expressly characterized by the sentencing court as a life sentence without parole, the
    State notes that two panels of this court previously held the Miller analysis does not apply
    to a hard 50 sentence. See Ellmaker v. State, No. 108,728, 
    2014 WL 3843076
     (Kan. App.
    2014) (unpublished opinion); State v. Redmon, No. 113,145, 
    2016 WL 5344034
     (Kan.
    App. 2016) (unpublished opinion). The defendant in Ellmaker was convicted of
    22
    premeditated first-degree murder committed when he was 17 years old. The sentencing
    court imposed a hard 50 sentence. After his conviction was affirmed on appeal, Ellmaker
    filed a K.S.A. 60-1507 motion claiming that his hard 50 sentence violated the Eighth
    Amendment's prohibition against cruel and unusual punishment under Miller because it
    was the functional equivalent of a sentence of life without parole. The district court
    denied the motion, and a panel of our court affirmed. The court held the Miller analysis
    does not apply to a hard 50 sentence because it is not the literal or functional equivalent
    of a life sentence without parole. In support of its holding, the panel relied on "the
    explicit way in which the United States Supreme Court has distinguished life without
    parole sentences and the death penalty and set them apart from all other sentences."
    Ellmaker, 
    2014 WL 3843076
    , at *10. Significantly, the panel did not consider the Miller
    case itself before ultimately holding that Miller did not apply. Instead, the panel limited
    its analysis to the categorical proportionality discussion in Graham.
    Two years later, another panel of this court cited Ellmaker approvingly to hold that
    the Miller rule does not apply to a 732-month (61-year) aggregate sentence for rape,
    aggravated burglary, aggravated robbery, and aggravated intimidation of a witness
    because the aggregated sentence was not the functional or literal equivalent of a life
    sentence without parole. Redmon, 
    2016 WL 5344034
    , at *6. The Redmon panel
    acknowledged, however, that a split of authority on the issue had become more prevalent
    since Ellmaker was decided, with other jurisdictions concluding that the rationale set
    forth in Graham and Miller applies equally to both sentences of life without parole and
    sentences that are the functional equivalent of life without parole. Nevertheless, the panel
    ultimately relied on Ellmaker to hold that the rule in Miller did not apply to a hard 50
    sentence. The panel did so without engaging in an analysis of the reasons provided by the
    Ellmaker panel for its decision or engaging in an analysis of the reasons for the mounting
    split in authority on the issue; the panel simply concluded it would be "reasonable" to go
    along with the holding in Ellmaker until the United States Supreme Court expressly
    resolved the issue. 
    2016 WL 5344034
    , at *6.
    23
    For the reasons stated below, we respectfully disagree with both the analysis and
    the holdings in Ellmaker and Redmon. See State v. Urban, 
    291 Kan. 214
    , 223, 
    239 P.3d 837
     (2010) (one panel not bound by decision of previous panel). "While we must
    carefully consider each precedent cited to us, we also must uphold our duty to correctly
    determine the law in each case that comes before us. In doing so, we sometimes find that
    we must respectfully disagree with the opinion of another panel." Uhlmann v.
    Richardson, 
    48 Kan. App. 2d 1
    , 13, 
    287 P.3d 287
     (2012).
    In Graham, Miller, and Montgomery, the United States Supreme Court placed
    constitutional limits on sentences that may be imposed on children. Graham held that
    children convicted of nonhomicide offenses cannot be sentenced to life without parole
    and must have a "realistic" and "meaningful opportunity to obtain release based on
    demonstrated maturity and rehabilitation." 560 U.S. at 74-75, 82. Miller and Montgomery
    mandate that the states must provide a juvenile convicted of homicide a meaningful
    opportunity to obtain release based on demonstrated maturity and rehabilitation except in
    the rarest of instances where the child is found to "exhibit[] such irretrievable depravity
    that rehabilitation is impossible." Montgomery, 136 S. Ct. at 733. In light of this mandate,
    one could not reasonably argue that a sentence fixed for a term of 100 years provides a
    meaningful opportunity for release, even though it is not characterized as a sentence of
    life without parole. So, at some point on the sentencing spectrum, a lengthy fixed
    sentence equates to a fixed life sentence without parole. Because the Supreme Court, 136
    S. Ct. at 733, has "counsel[ed] against irrevocably sentencing [juveniles] to a lifetime in
    prison" without consideration of the Miller factors, we conclude a sentence that fails to
    provide an opportunity for release at a meaningful point in a juvenile's life triggers Eighth
    Amendment protections, regardless of whether it is labeled life without parole, life with
    parole, or a term of years. A contrary conclusion lacks support in reason and practice as it
    necessarily allows a sentencer to circumvent the Eighth Amendment prohibition against
    cruel and unusual punishment simply by expressing the sentence in the form of a lengthy
    term of numerical years rather than labeling for what it is: a life sentence without parole.
    24
    And although not a categorical proportionality claim, we find the discussion in
    Graham regarding the absence of any legitimate penological justification for a sentence
    of life without parole to be just as persuasive in the context of considering whether the
    rule in Miller is triggered for a lengthy juvenile sentence for a term of years that is the
    functional equivalent of life without parole. See Graham, 560 U.S. at 71. The Supreme
    Court considered whether any theory of penal sanction could provide an adequate
    justification for sentencing a juvenile nonhomicide offender to life without parole and
    found none. The same test applied to a sentence of a lengthy term of years without
    eligibility for parole yields the same conclusion. The Graham Court's reasoning
    regarding retribution is equally applicable to a lengthy term-of-years sentence as it is to
    one labeled as "life." Sentences must directly relate to the personal culpability of the
    offender, which is diminished in the case of a juvenile offender who has not committed
    homicide. 560 U.S. at 71-72. In terms of deterrence, "'the same characteristics that render
    juveniles less culpable than adults suggest . . . that juveniles will be less susceptible to
    deterrence.'" 560 U.S. at 72. Regardless of what the punishment is, children are "less
    likely to take a possible punishment into consideration when making decisions,"
    especially "when that punishment is rarely imposed." 560 U.S. at 72. There is no reason
    to believe that a juvenile would be deterred from crime depending on whether the
    sentence was life without parole or a number of years that is the functional equivalent of
    life without parole. Finally, there is no difference in terms of rehabilitation or
    incapacitation between two sentences that would both incarcerate the defendant for the
    functional equivalent of the defendant's life. Neither type of sentence contemplates the
    defendant returning to society for a period of time that is the functional equivalent of a
    term of life, either as a reformed citizen or as a potential threat.
    Most courts that have considered the issue focus not on the label attached to a
    sentence but instead on whether imposing the sentence would violate the principles
    Miller and Graham sought to effectuate. See Williams v. United States, 
    205 A.3d 837

    In applying the rule in Miller, we note that some of these courts did not ultimately
    conclude that the term of years to which the offender was sentenced rose to the level of
    cruel and unusual punishment under the Eighth Amendment. But critical to the issue
    presented in answering our question—whether a sentence expressed as a term of years
    can ever be equivalent to a sentence of life without parole—all of the courts applied the
    legal principles announced in Graham and Miller to a term of years sentence. In
    constitutional terms, these courts both explicitly and implicitly agreed that the substantive
    protections afforded to juveniles in the mandatory life without parole context should
    similarly flow to juveniles who are sentenced to a term of years that is the functional
    26
    equivalent of a sentence of life without parole. It stands to reason that, at least for the vast
    majority of juvenile offenders who are not deemed irredeemable, imposition of a
    sentence for a term of years that is the functional equivalent of life without parole
    unconstitutionally thwarts those juveniles' opportunities for release under both Graham
    and Miller.
    We are persuaded by our own analysis and the compilation of cases set forth
    above holding that a sentence expressed as a term of years that fails to provide an
    opportunity for release at a meaningful point in a juvenile's life triggers the Eighth
    Amendment protections announced in Miller. Nevertheless, we acknowledge that there is
    a split of authority among the states and the federal circuits on the issue. See United
    States v. Sparks,

    case where trial court imposed six consecutive life sentences plus 60 additional years on
    juvenile who committed multiple offenses); Nathan, 522 S.W.3d at 891 ("Miller has no
    application to Nathan's second-degree murder conviction, which does not call for
    mandatory life in prison without the possibility of parole, or to his multitude of
    nonhomicide convictions because Miller did not address the constitutional validity of
    27
    consecutive sentences, let alone the cumulative effect of such sentences."); Johnson v.
    Commonwealth, 
    292 Va. 772
    , 780-82, 
    793 S.E.2d 326
     (2016) (finding that Miller does
    not apply in cases where juvenile is ordered to serve aggregate life sentence and has
    opportunity to be considered for parole).
    While acknowledging the split in authority, we find the conclusion in these
    cases—that Miller categorically does not apply to a sentence expressed as a term of
    years—is inconsistent with the reasoning of Roper, Graham, and Miller, in which the
    Supreme Court repeatedly emphasized the lessened culpability of juvenile offenders, the
    difficulty in determining which juvenile offender is one of the very few that is
    irredeemable, and the importance of a "meaningful opportunity to obtain release based on
    demonstrated maturity and rehabilitation." Graham, 560 U.S. at 75. In fact, the
    fundamental premise underlying the Court's decisions in both Graham and Miller is the
    recognition that juveniles are more amenable to rehabilitation than adults because they
    are less mature and are not fully developed, they lack the same culpability of an adult,
    and they have behavior that is transient. Those variances do not vanish simply because
    the sentence is for a lengthy term of years instead of life without parole. The
    constitutional framework upon which the Court in Graham and Miller constructed its
    holdings reflects that much more is at stake in the sentencing of juveniles than merely
    making sure that parole is possible. A juvenile offender sentenced to a lengthy term of
    years sentence should not be worse off than a juvenile offender sentenced to life in prison
    without parole who has the benefit of an individualized hearing under Miller.
    Accordingly, we hold the constitutional protections afforded under Miller are triggered
    when a juvenile offender convicted of premeditated first-degree murder is subject to a
    sentence for a term of years that is the functional equivalent to a sentence of life without
    parole.
    28
    b. Hard 50 sentence is the functional equivalent to life without parole.
    We now must decide whether the hard 50 sentence imposed on Williams is the
    functional equivalent of a sentence of life without parole. "Courts that have grappled with
    the issue of how lengthy a sentence must be to trigger the protections of Miller often
    reference Graham's instruction that juvenile offenders must retain a meaningful
    opportunity for release." Premo, 365 Or. at 14 (citing Null, 836 N.W.2d at 71-72
    ["explaining that it does 'not regard the juvenile's potential future release in his or her late
    sixties after a half century of incarceration sufficient to escape the rationales of Graham
    or Miller'"]); Casiano v. Comm'r of Corr., 
    317 Conn. 52
    , 73-75, 
    115 A.3d 1031
     (noting
    that most courts that have considered the issue have determined that a sentence that
    exceeds life expectancy or that would make the individual eligible for release near the
    end of his or her life expectancy is a de facto life sentence).
    In this case, Williams must serve a minimum of 50 years in prison for his single
    conviction before he can be considered for release. We are unaware of any state high
    court that has found a single sentence in excess of 50 years for a single homicide provides
    a juvenile with a meaningful opportunity for release. See People v. Contreras, 
    4 Cal. 5th 349
    , 369, 
    229 Cal. Rptr. 3d 249
    , 
    411 P.3d 445
     (2018) (same for 50-year-to-life sentence);
    Casiano, 317 Conn. at 73, 79-80 (same for 50-year sentence); Null, 836 N.W.2d at 71
    (same for 75-year sentence with parole eligibility after 52.5 years); Zuber, 227 N.J. at 448
    (110-year sentence with parole eligibility after 55 years and 75-year sentence with parole
    eligibility after 68 years and 3 months "is the practical equivalent of life without parole");
    White, 365 Or. at 15 (same for nearly 67-year sentence); Bear Cloud, 334 P.3d at 141-42
    (same for 45-year-to-life sentence). In finding that a juvenile defendant's 50-year
    sentence is equivalent to life without parole for purposes of applying Miller, the
    Connecticut Supreme Court relied on Miller and Graham to construe the concept of life
    more broadly than biological survival; specifically, it found that the United States
    Supreme Court "implicitly endorsed the notion that an individual is effectively
    29
    incarcerated for 'life' if he [or she] will have no opportunity to truly reenter society or
    have any meaningful life outside of prison." Casiano, 317 Conn. at 78.
    We conclude Williams' hard 50 sentence is the functional equivalent to life
    without parole for purposes of applying the rule in Miller.
    3. Individualized consideration of a juvenile's youth and attendant characteristics
    We now address Williams' claim that he was deprived of the constitutional
    protections afforded by Miller when the sentencing court failed to consider his
    diminished culpability and heightened capacity for change before imposing the hard 50
    sentence. The applicable statute required the sentencing court to consider an exclusive set
    of statutory aggravating circumstances and a nonexclusive set of statutory mitigating
    circumstances in deciding whether to impose a hard 25 or a hard 50 sentence on
    Williams. See K.S.A. 1999 Supp. 21-4635(b). This statute applies to adults and juveniles
    alike, regardless of age. There is an enumerated mitigating circumstance in the statute
    that prompts the court to consider the "age of the defendant at the time of the crime" but,
    again, that consideration applies equally to adults and children alike. See K.S.A. 21-
    4637(g). As the Supreme Court in Miller observed, "'youth is more than a chronological
    fact.'" 
    567 U.S. at 476
    . The sentencing court's mere awareness of the fact that Williams
    was 14 years old at the time he committed the crime does not provide any evidence that
    the court specifically considered Williams' youth and its attendant characteristics.
    There is nothing in the hard 50 sentencing scheme that facilitates the court's
    consideration of the characteristics and circumstances attendant to a juvenile offender's
    age or the fact that juveniles have diminished culpability and greater prospects for
    reform. And our review of the sentencing transcript reflects that the sentencing court did
    not consider any of the unique characteristics attendant to Williams' age, his diminished
    culpability, or prospects for reform before imposing the hard 50 sentence. We are not
    30
    surprised by this fact because Williams was sentenced in 2001, which was 11 years
    before Miller established the rule requiring individualized sentencing considerations for
    juveniles before imposing a sentence of life without parole or, in this case, its functional
    equivalent. See Miller, 
    567 U.S. at 489
    .
    The State relied on the existence of four statutory aggravating circumstances to
    argue in favor of a hard 50 sentence for Williams: (1) he knowingly or purposely killed
    more than one person, (2) he committed the crime for the purpose of receiving money,
    (3) he committed the crime to avoid or prevent a lawful arrest or prosecution, and (4) he
    committed the crime in an especially heinous, atrocious, or cruel manner. K.S.A. 1999
    Supp. 21-4636(b), (c), (e), (f).
    Defense counsel disputed the existence of any of the statutory aggravating
    circumstances, except the killing of more than one person. Counsel relied on the expert's
    trial testimony to argue that the murders were "really a senseless act committed by a
    person who has a deficiency in understanding what he is doing." Counsel went on to
    argue that any aggravating circumstances the court found were outweighed by mitigating
    circumstances: his youth, his mental capacity, and his emotional state at the time of the
    offense. Counsel referenced the testimony of the clinical psychologist who found
    Williams had markedly impaired abilities to perceive and conceive of sequence of events.
    Counsel argued the case boiled down to Williams' inability "to think through the
    situation, define options, foretell consequences, make enlightened or objective choices,
    strategize and see those factors as—ahead before acting is deficient. And he is slow in
    processing, therefore will not examine, observe or—violent thoughts on his own."
    People who knew Williams spoke on his behalf, each requesting the court impose
    a hard 25 sentence instead of a hard 50 sentence. A middle school teacher spoke to the
    absence of parents or other support systems in Williams' life growing up. An individual
    who employed Williams over the summer on some property she managed described
    31
    Williams as respectful, mannerable, very disciplined, and a person with potential. She
    expressed hope that "he could be put into some type of situation where he's not just
    thrown away and the key thrown away with him."
    The adult child of the two victims killed by Williams spoke on behalf of the
    family, explaining how wonderful his parents were and the devastating impact his
    parents' murders had on his adult siblings, their children, and his parents' siblings.
    After hearing the arguments of counsel and the statements of these various
    individuals, the court imposed a hard 50 sentence for each of the two first-degree murder
    charges. In support of its decision to impose the hard 50 sentence instead of the hard 25
    sentence, the court noted that in cases like these, it had a duty to find a middle ground
    between a defendant's request for mercy and a victim's request for justice. Immediately
    after framing its duty in this way, the district court judge stated:
    "The time to have helped Ronnell Williams was before this date, August of 1999.
    I mean, we talk about and we—we rail about and we—we bemoan the fact that this and
    that wasn't done for him. And now, you know, when it's too late, you can do something
    for him.
    "Whatever it was that drew him and his brother to that address on that date and
    whatever it was that made him do the things that he did, and I confess, I will never know.
    I mean, I look at you and I—I don't have a clue as to what motivated you. And you've
    given me absolutely nothing to help me figure out what—what happened. To be honest
    with you, I frankly don't even think you know or that you have an answer for that."
    (Emphasis added.)
    The court advised Williams that the decision he made on the day of the murders not only
    ruined his own life but the life of the victims and their surviving family members. The
    court then made a formal finding that the aggravating factors outweighed any mitigating
    factors presented.
    32
    The sentencing court did not consider any characteristics and circumstances
    attendant to Williams' age or the fact that, as a child, he was constitutionally different
    from adults for purposes of sentencing because juveniles have diminished culpability and
    greater prospects for reform. In fact, the italicized language above reflects that the court
    considered this 14-year-old boy, a child in middle school with no criminal history, to
    have zero possibility for reform and therefore was entitled to the most severe sentence
    that could be imposed (even on an adult) for the crime committed: life without the
    possibility of parole for 50 years.
    We find Williams was deprived of the constitutional protections afforded by
    Miller, which require the sentencing court to consider his diminished culpability and
    heightened capacity for change before imposing the hard 50 sentence for his conviction
    of premeditated first-degree murder.
    4. Conclusion
    A sentencing court cannot impose a hard 50 sentence on a juvenile offender
    convicted of premediated first-degree murder without first considering the offender's
    youth and attendant characteristics, including the child's diminished culpability and
    heightened capacity for change, while keeping in mind that such a sentence is
    constitutionally disproportionate for all but the rarest of children whose crimes reflect
    irreparable corruption. We emphasize that neither Miller, the Eighth Amendment, nor our
    opinion in this case categorically prohibit a sentencing court from imposing a life
    sentence on a juvenile in all cases. The problem lies not with the potential substance of
    the sentence but with the procedure by which the court makes its decision to impose it.
    As Miller noted: "Although we do not foreclose a sentencer's ability to make that
    judgment in homicide cases, we require it to take into account how children are different,
    and how those differences counsel against irrevocably sentencing them to a lifetime in
    prison." 
    567 U.S. at 480
    . Our decision today does not disturb the finality of state
    33
    convictions. Those juvenile offenders with irretrievable depravity, permanent
    incorrigibility, or irreparable corruption beyond the possibility of rehabilitation will
    continue to serve hard 50 sentences. The opportunity for parole or release before 50 years
    has passed will be afforded to those who "demonstrate the truth of Miller's central
    intuition—that children who commit even heinous crimes are capable of change."
    Montgomery, 136 S. Ct. at 736.
    C. Remedy
    Williams asks this court to vacate his hard 50 sentence under K.S.A. 60-1507 and
    remand for a new sentencing hearing at which the court would be required to consider his
    youth and its attendant characteristics as set forth in Miller. Under K.S.A. 2019 Supp. 60-
    1507(a), "[a] prisoner in custody under sentence of a court of general jurisdiction
    claiming the right to be released upon the ground that the sentence was imposed in
    violation of the constitution or laws of the United States" may "move the court which
    imposed the sentence to vacate, set aside or correct the sentence." If the court finds that
    the constitutional rights of the prisoner have been denied or infringed upon so as to
    render the judgment vulnerable to collateral attack, "the court shall vacate and set the
    judgment aside and shall discharge the prisoner or resentence said prisoner or grant a new
    trial or correct the sentence as may appear appropriate." K.S.A. 2019 Supp. 60-1507(b).
    Because Williams was deprived of the constitutional protections afforded by
    Miller, he is entitled to habeas relief in the form of an evidentiary hearing. See K.S.A.
    2019 Supp. 60-1507(b). To that end, we remand the matter to the district court to
    determine whether imposing a hard 50 sentence on Williams for the offense of
    premeditated first-degree murder was constitutionally disproportionate under the Eighth
    Amendment. We specifically decline, however, to vacate Williams' sentence. A district
    court's sentence is final when initially pronounced from the bench. See State v. Guder,
    
    293 Kan. 763
    , Syl. ¶ 2, 
    267 P.3d 751
     (2012). District courts generally are prohibited from
    34
    modifying sentences that have not been vacated by the appellate court. State v. Warren,
    
    307 Kan. 609
    , Syl. ¶ 1, 612-13, 
    412 P.3d 993
     (2018). But the plain language of K.S.A.
    60-1507 expressly provides the district court with the authority to vacate the sentence or
    provide other appropriate relief. See K.S.A. 2019 Supp. 60-1507(a) (habeas prisoner
    alleging sentence imposed in violation of the Constitution or laws of the United States or
    Kansas may move the court which imposed the sentence to vacate, set aside, or correct
    the sentence); K.S.A. 2019 Supp. 60-1507(b) (if habeas court finds that sentence imposed
    violates constitutional rights of movant, court may correct and resentence prisoner as
    appropriate). So if the habeas court on remand determines that imposing a hard 50
    sentence on Williams for the offense of premeditated first-degree murder is
    constitutionally disproportionate under the Eighth Amendment, then the unconstitutional
    hard 50 sentence can be vacated or modified to a constitutionally proportionate sentence
    by the habeas court.
    Finally, we look to Graham, Miller, and Montgomery for guidance in directing the
    habeas court on remand. In Miller, the Supreme Court held that a juvenile defendant may
    be sentenced to life imprisonment without parole but only if the sentencing court
    determines that the defendant's conduct showed irretrievable depravity, permanent
    incorrigibility, or irreparable corruption beyond the possibility of rehabilitation. See 
    567 U.S. at 471-73, 479-80
    . The sentencing court may make that decision only after
    considering the defendant's youth and its attendant characteristics. Those characteristics
    include, but are not limited to, the following:
     Consideration of the juvenile offender's chronological age and its hallmark
    features—among them, immaturity, impetuosity, and failure to appreciate risks
    and consequences;
    35
     Consideration of the family and home environment that surrounds the juvenile
    offender—and from which the juvenile offender cannot usually extricate himself
    or herself—no matter how brutal or dysfunctional;
     Consideration of the circumstances of the homicide offense, including the extent
    of the juvenile offender's participation in the conduct and the way familial and
    peer pressures may have affected the juvenile offender;
     Consideration of the possibility that the juvenile offender might have been charged
    and convicted of a lesser offense if not for incompetencies associated with
    youth—for example, the juvenile offender's inability to deal with police officers or
    prosecutors (including on a plea agreement) or the incapacity to assist his or her
    own attorneys; and
     Consideration of the juvenile offender's prospects for rehabilitation. See Miller,
    
    567 U.S. at 477-78
    .
    After identifying these characteristics as relevant considerations to determine a
    child's diminished culpability and heightened capacity for change, the Miller Court stated
    its belief that imposing a sentence of life without parole on a juvenile after considering
    these characteristics "will be uncommon. That is especially so because of the great
    difficulty we noted in Roper and Graham of distinguishing at this early age between 'the
    juvenile offender whose crime reflects unfortunate yet transient immaturity, and the rare
    juvenile offender whose crime reflects irreparable corruption.'" Miller, 
    567 U.S. at
    479-
    80 (quoting Roper, 
    543 U.S. at 573
    ; Graham, 560 U.S. at 68).
    Although we have summarized the list of characteristics identified by the Miller
    Court as relevant to consider before imposing a sentence of life without parole for a
    juvenile convicted of homicide, we emphasize that this list is not exclusive. At
    36
    resentencing, the habeas court may consider any characteristic it finds to be relevant in
    deciding the issue before it: whether imposing a hard 50 sentence on Williams for the
    offense of premeditated first-degree murder is constitutionally disproportionate under the
    Eighth Amendment considering Williams' age at the time he committed the crime and its
    attendant characteristics, including his diminished culpability and heightened capacity for
    change.
    We find additional guidance necessary on three more issues. The first issue relates
    to the decision of the original sentencing court to run both of Williams' hard 50 sentences
    concurrent to each other. The concurrent nature of these sentences was not an issue
    addressed by the parties on appeal, and we expressly exclude it from review on remand
    for purposes of our mandate.
    The second issue concerns the scope of evidence that can be considered by the
    habeas court in deciding whether the hard 50 sentence imposed on Williams is
    constitutionally disproportionate given his age at the time he committed the crime and its
    attendant characteristics, including his diminished culpability and heightened capacity for
    change. Specifically, whether the court is limited to considering the evidence that was
    available at the time Williams originally was sentenced or whether the court can consider
    what has happened since Williams was placed in prison. Under Miller, the court must
    consider youth and its attendant characteristics at the time of sentencing to "take into
    account how children are different, and how those differences counsel against irrevocably
    sentencing them to a lifetime in prison." Miller, 
    567 U.S. at 480
    . But Graham explains
    that the Constitution "prohibit[s] States from making the judgment at the outset that [a
    juvenile] never will be fit to reenter society." 560 U.S. at 75. The Court later highlighted
    that Graham's sentence violated the Eighth Amendment because the state "denied him
    any chance to later demonstrate that he is fit to rejoin society." 560 U.S. at 79. And most
    significantly, the Montgomery Court specifically held that the petitioner's submissions
    regarding his evolution from a troubled, misguided youth to a model member of the
    37
    prison community are relevant to show an example of one kind of evidence that prisoners
    might use to demonstrate rehabilitation. 136 S. Ct. at 736 (although factual claims on
    appeal had not been established at an evidentiary hearing, the Court found relevant for
    consideration by the district court on remand that since imprisoned, Montgomery had
    helped establish an inmate boxing team, of which he later became a trainer and coach,
    that he had contributed his time and labor to the prison's silkscreen department, and that
    he strived to offer advice and serve as a role model to other inmates).
    As noted above, the issue before the court at resentencing will be whether
    imposing a hard 50 sentence on Williams is constitutionally disproportionate under the
    Eighth Amendment considering his age at the time he committed the crime and its
    attendant characteristics, including his diminished culpability and heightened capacity for
    change. In assessing Williams' capacity for change, the court must be able to consider all
    facts relevant to deciding the issue, including evidence of whether Williams has, in fact,
    worked toward rehabilitation in the 20-plus years since he committed his crimes. To
    ignore that evidence in favor of a retrospective analysis of whether Williams had a
    heightened capacity for change at the time he committed his crime (or on the date of
    sentencing) is a useless exercise of speculation. If Williams is irretrievably depraved,
    permanently incorrigible, or irreparably corrupt, evidence from the past 20 years will bear
    that out.
    The third issue provides guidance to the district court in the event it finds
    Williams' original sentence unconstitutionally disproportionate. At the time Williams was
    sentenced, the default sentence for premeditated first-degree murder was life without the
    possibility of parole for 25 years. See K.S.A. 1999 Supp. 21-4706(c); K.S.A. 1999 Supp.
    22-3717(b)(1). Williams' sentence was enhanced to a hard 50 sentence based on the
    sentencing court's finding, by a preponderance of the evidence, that one or more
    aggravating circumstances existed and that the aggravators were not outweighed by
    mitigating circumstances. See K.S.A. 1999 Supp. 21-4635(c); State v. Spain, 
    263 Kan. 38
    708, 714, 
    953 P.2d 1004
     (1998) (holding that "the implicit standard of proof for
    aggravating circumstances under K.S.A. 21-4635[c] is preponderance of the evidence").
    But in 2013, the United States Supreme Court issued its opinion in Alleyne v.
    United States, 
    570 U.S. 99
    , 
    133 S. Ct. 2151
    , 
    186 L. Ed. 2d 314
     (2013). Alleyne held that
    the facts a sentencing court relies upon to increase an offense's mandatory minimum
    sentence are elements of that enhanced offense. As such, those sentence-enhancing facts
    must be proved to a jury beyond a reasonable doubt to avoid a violation of the
    defendant's Sixth Amendment right to jury trial. 570 U.S. at 114-15. Following Alleyne,
    the Kansas Legislature held a special session in September 2013 to amend Kansas' hard
    50 sentencing scheme. See L. 2013, ch. 1, § 1 (Special Session). Relevant here, the
    amended statute requires that a jury must find beyond a reasonable doubt that at least one
    aggravating circumstance exists and that the aggravating circumstance(s) are not
    outweighed by any mitigating circumstances before the court can enhance the sentence of
    a defendant convicted of first-degree premeditated murder from a hard 25 to a hard 50
    sentence. K.S.A. 2013 Supp. 21-6620(b), (c).
    On the issue of retroactivity, the amended statute provides that the amendments
    "shall not apply to cases in which the defendant's conviction and sentence were final prior
    to June 17, 2013, unless the conviction or sentence has been vacated in a collateral
    proceeding, including, but not limited to, K.S.A. 22-3504 or 60-1507, and amendments
    thereto." K.S.A. 2013 Supp. 21-6620(d). The amended statute also provides:
    "(e) Notwithstanding the provisions of subsection (f), for all cases on appeal on
    or after the effective date of this act, if a sentence imposed under this section, prior to
    amendment by this act, or under K.S.A. 21-4635, prior to its repeal, is vacated for any
    reason other than sufficiency of the evidence as to all aggravating circumstances,
    resentencing shall be required under this section, as amended by this act, unless the
    prosecuting attorney chooses not to pursue such a sentence.
    39
    "(f) In the event any sentence imposed under this section is held to be
    unconstitutional, the court having jurisdiction over a person previously sentenced shall
    cause such person to be brought before the court and shall sentence such person to the
    maximum term of imprisonment otherwise provided by law." K.S.A. 2013 Supp. 21-
    6620(e), (f).
    Although the Legislature amended the statute in 2014 and again in 2017, the substance of
    the language quoted above has not changed. See K.S.A. 2019 Supp. 21-6620(f), (g), (h).
    Bottom line, in the event the district court finds it necessary to vacate Williams'
    original sentence because it was unconstitutionally disproportionate, the court must
    comply with the statutory directives set forth in K.S.A. 2019 Supp. 21-6620(e), (f), (g),
    and (h) when resentencing Williams. In doing so, the district court should determine in
    the first instance whether that process will result in a constitutionally satisfactory
    sentence comporting with Miller and, if not, how then to sentence Williams consistent
    with K.S.A. 2019 Supp. 21-6620.
    D. Lifetime postrelease supervision
    When the sentencing court ordered Williams to serve a hard 50 sentence, it also
    imposed lifetime postrelease supervision. For the first time on appeal, Williams argues
    that the district court's imposition of lifetime postrelease supervision renders his sentence
    illegal. "The court may correct an illegal sentence at any time while the defendant is
    serving such sentence." K.S.A. 2019 Supp. 22-3504(a); see State v. Kelly, 
    298 Kan. 965
    ,
    975-76, 
    318 P.3d 987
     (2014) (defendant may challenge illegal sentence for first time on
    appeal). Whether a sentence is illegal under K.S.A. 2019 Supp. 22-3504 is a question of
    law over which an appellate court has unlimited review. State v. Lee, 
    304 Kan. 416
    , 417,
    
    372 P.3d 415
     (2016).
    40
    "A sentence is illegal under K.S.A. 22-3504 when: (1) it is imposed by a court
    without jurisdiction; (2) it does not conform to the applicable statutory provisions, either
    in character or punishment; or (3) it is ambiguous with respect to the time and manner in
    which it is to be served." State v. Hayes, 
    307 Kan. 537
    , 538, 
    411 P.3d 1225
     (2018).
    Williams argues that the sentencing court lacked jurisdiction to impose lifetime
    postrelease supervision. The State agrees. "An inmate who has received an off-grid
    indeterminate life sentence can leave prison only if the [Kansas Prisoner Review] Board
    grants the inmate parole. Therefore, a sentencing court has no authority to order a term of
    postrelease supervision in conjunction with an off-grid indeterminate life sentence." State
    v. Cash, 
    293 Kan. 326
    , Syl. ¶ 2, 
    263 P.3d 786
     (2011); see State v. Harsh, 
    293 Kan. 585
    ,
    590, 
    265 P.3d 1161
     (2011) (parole is separate and distinct from sentence; if defendant
    with off-grid indeterminate life sentence ever leaves prison, it will be because parole was
    granted). Williams' off-grid sentence permits parole eligibility after 50 years have been
    served, not lifetime postrelease supervision. See State v. Ross, 
    295 Kan. 1126
    , 1134, 
    289 P.3d 76
     (2012) (defendant who received off-grid life sentence for felony murder was
    subject to lifetime parole instead of lifetime postrelease supervision).
    Because the sentencing court erred in imposing lifetime postrelease supervision,
    that portion of Williams' sentence must be vacated. See State v. Johnson, 
    309 Kan. 992
    ,
    997-98, 
    441 P.3d 1036
     (2019) (vacating order of lifetime postrelease supervision rather
    than remanding case for resentencing); State v. Floyd, 
    296 Kan. 685
    , 690-91, 
    294 P.3d 318
     (2013) (same).
    CONCLUSION
     We find Williams sufficiently showed the manifest injustice and exceptional
    circumstances necessary to justify the untimely and successive filing of his second
    K.S.A. 60-1507 motion. Accordingly, we reverse the district court's decision to
    41
    summarily deny Williams' habeas claim for relief and remand to the district court
    to hold an evidentiary hearing.
     We hold the constitutional protections afforded under Miller are triggered
    regardless of whether the sentencing scheme is mandatory or discretionary.
     We find Williams' hard 50 sentence is the functional equivalent of a sentence of
    life without parole for purposes of the constitutional protections in Miller.
     We find Williams was deprived of the constitutional guarantees afforded under
    Miller because the sentencing court failed to fully consider his diminished
    culpability and heightened capacity for change before imposing the hard 50
    sentence on him. Based on this constitutional deprivation, we remand this K.S.A.
    60-1507 matter to the habeas court to hold an evidentiary hearing. At the hearing,
    the habeas court must specifically consider evidence about whether imposing a
    hard 50 sentence on Williams for the offense of premeditated first-degree murder
    is constitutionally disproportionate under the Eighth Amendment given Williams'
    age at the time he committed the crime and its attendant characteristics.
     In considering the evidence presented on remand, the habeas court shall expressly
    decide whether Williams is irretrievably depraved, permanently incorrigible, or
    irreparably corrupt beyond the possibility of rehabilitation. In making this
    decision, the habeas court must consider, at a minimum, the following
    circumstances with regard to Williams' diminished culpability and heightened
    capacity for change, while keeping in mind that such a sentence is constitutionally
    disproportionate for all but the rarest of children whose crimes reflect irreparable
    corruption:
    42
    o Williams' chronological age at the time of the crime and its hallmark
    features—among them, immaturity, impetuosity, and failure to appreciate
    risks and consequences.
    o Williams' family and home environment that surrounded him at the time of
    the crime.
    o The circumstances of the homicide offense, including the extent of
    Williams' participation in the conduct and the way familial and peer
    pressures may have affected him.
    o The possibility that Williams might have been charged and convicted of a
    lesser offense if not for incompetencies associated with youth—for
    example, Williams' inability to deal with police officers or prosecutors
    (including on a plea agreement) or the incapacity to assist his own
    attorneys.
    o Williams' prospects for rehabilitation at the time of the crime as well as
    whether Williams has, in fact, worked toward rehabilitation in the 20-plus
    years since he committed his crimes.
     On remand, the habeas court shall not consider the concurrent nature of Williams'
    two hard 50 sentences in deciding whether imposing a hard 50 sentence on
    Williams for the offense of premeditated first-degree murder is constitutionally
    disproportionate under the Eighth Amendment given Williams' age at the time he
    committed the crime and its attendant characteristics.
     If the habeas court determines on remand that imposing a hard 50 sentence on
    Williams for the offense of premeditated first-degree murder is constitutionally
    43
    disproportionate under the Eighth Amendment, then the unconstitutional hard 50
    sentence is necessarily rendered illegal and the habeas court has jurisdiction to
    vacate the sentence and set the matter to impose a sentence that complies with the
    constitutional mandate in Miller and with the statutory directives set forth in
    K.S.A. 2019 Supp. 21-6620.
     Both the evidentiary hearing—and any later hearings on sentencing disposition
    that may be held—must reflect that the habeas court meaningfully engaged in
    Miller's central inquiry.
     That part of Williams' sentence imposing lifetime postrelease supervision is
    vacated.
    Reversed, sentence vacated in part, and case remanded with directions.
