    Opinion
    McDONALD, J. In a recent trilogy of cases, the United
    States Supreme Court fundamentally altered the legal
    landscape for the sentencing of juvenile offenders1 to
    comport with the ban on cruel and unusual punishment
    under the eighth amendment to the federal constitution.
    The court first barred capital punishment for all juvenile
    offenders; Roper v. Simmons, 
    543 U.S. 551
    , 575, 125 S.
    Ct. 1183, 
    161 L. Ed. 2d 1
    (2005); and then barred life
    imprisonment without the possibility of parole for juve-
    nile nonhomicide offenders. Graham v. Florida, 
    560 U.S. 48
    , 79–80, 
    130 S. Ct. 2011
    , 
    176 L. Ed. 2d 825
    (2010).
    Most recently, in Miller v. Alabama,         U.S.    , 
    132 S. Ct. 2455
    , 2460, 
    183 L. Ed. 2d 407
    (2012), the court
    held that mandatory sentencing schemes that impose
    a term of life imprisonment without parole on juvenile
    homicide offenders, thus precluding consideration of
    the offender’s youth as mitigating against such a severe
    punishment, violate the principle of proportionate pun-
    ishment under the eighth amendment.
    Miller did not specifically address the constitutional
    parameters of when a life sentence without parole may
    be imposed in the exercise of the sentencing authority’s
    discretion on a juvenile homicide offender. The present
    case requires us to consider this question.
    The defendant, Ackeem Riley, was seventeen years
    old when he committed homicide and nonhomicide
    offenses for which the trial court imposed, in the exer-
    cise of its discretion, a total effective sentence of 100
    years imprisonment. The defendant has no possibility
    of parole before his natural life expires. In his certified
    appeal to this court, the defendant claims that his sen-
    tence and the procedures under which it was imposed
    violate Graham and Miller, and, hence, the eighth
    amendment. Specifically, the defendant contends that:
    (1) Miller required the trial court to consider his youth
    and circumstances attendant to his youth as mitigating
    against the functional equivalent to a life sentence with-
    out parole when exercising its sentencing discretion;
    and (2) if the trial court imposes the functional equiva-
    lent to a life sentence in the exercise of its discretion,
    Graham requires that he be afforded a subsequent
    opportunity to obtain release based on his demon-
    strated maturity and rehabilitation.
    We agree with the defendant’s Miller claim. There-
    fore, he is entitled to a new sentencing proceeding at
    which the court must consider as mitigation the defen-
    dant’s age at the time he committed the offenses and
    the hallmarks of adolescence that Miller deemed consti-
    tutionally significant when a juvenile offender is subject
    to a potential life sentence. We decline, however, to
    address the defendant’s Graham claim. As we explain
    later in this opinion, the legislature has received a sen-
    tencing commission’s recommendations for reforms to
    our juvenile sentencing scheme to respond to the dic-
    tates of Graham and Miller. Therefore, in deference to
    the legislature’s authority over such matters and in light
    of the uncertainty of the defendant’s sentence upon due
    consideration of the Miller factors, we conclude that
    it is premature to determine whether it would violate
    the eighth amendment to preclude any possibility of
    release when a juvenile offender receives a life
    sentence.
    We begin with a brief overview of the facts that the
    jury reasonably could have found and the procedural
    history of this case. In November, 2006, when the defen-
    dant was seventeen years old, he participated in a drive-
    by shooting into a crowd that left an innocent sixteen
    year old dead and two other innocent bystanders, ages
    thirteen and twenty-one, seriously injured. The defen-
    dant and his accomplice thought that someone respon-
    sible for a gang related shooting the previous week was
    at the scene. The defendant’s identity as one of the
    perpetrators was corroborated by his involvement in
    an incident two months after the crimes at issue in
    which a firearm was discharged that matched the
    weapon used in the 2006 shootings. A jury convicted
    the defendant of one count of murder in violation of
    General Statutes §§ 53a-54a (a) and 53a-8, two counts
    of attempt to commit murder in violation of General
    Statutes §§ 53a-49 (a) (2) and 53a-54a (a), two counts
    of assault in the first degree in violation of General
    Statutes §§ 53a-59 (a) (5) and 53a-8, and one count of
    conspiracy to commit murder in violation of General
    Statutes §§ 53a-48 (a) and 53a-54a (a). The murder con-
    viction exposed the defendant to a potential sentence
    of twenty-five to sixty years imprisonment, with no
    possibility of parole. See General Statutes §§ 53a-35a
    (2), 53a-35b and 54-125a (b) (1) (E). The other convic-
    tions exposed him to sentences ranging from one year
    imprisonment to twenty years imprisonment.
    The trial court ultimately imposed a total effective
    sentence of 100 years imprisonment. It is undisputed
    that this sentence is the functional equivalent to life
    without the possibility of parole.2 See State v. Riley,
    
    140 Conn. App. 1
    , 3 n.2, 
    58 A.3d 304
    (2013). In stating
    its basis for imposing this sentence, the trial court made
    no reference to the defendant’s age at the time he com-
    mitted the offenses. After the trial court rendered judg-
    ment in the present case in 2009, the United States
    Supreme Court issued its decision in Miller.
    In his appeal to the Appellate Court, the defendant
    contended that his sentence and the procedure under
    which it was imposed violated his rights under the
    eighth and fourteenth amendments to the federal consti-
    tution. 
    Id., 4, 10
    and n.7. A majority of the Appellate
    Court rejected these contentions. 
    Id., 4. The
    majority
    concluded that Miller requires only that a defendant be
    afforded the opportunity to present mitigating evidence,
    including evidence relating to his age, and that the court
    be permitted to impose a lesser sentence than life with-
    out parole after considering any such evidence. 
    Id., 10, 14–16.
    It determined that Connecticut’s sentencing
    scheme comported with these requirements. 
    Id., 18. The
    majority further concluded that the trial court in the
    present case had in fact considered many of the factors
    identified as relevant in Miller before imposing the
    defendant’s sentence. 
    Id., 19–21. In
    his dissenting opin-
    ion, Judge Borden disagreed with each of these determi-
    nations and concluded that the defendant was entitled
    to a new sentencing proceeding. 
    Id., 23–40. Judge
    Bor-
    den further opined that, if a trial court determines that
    a life sentence is appropriate after giving due weight
    to the offender’s youth, Graham requires the court to
    provide for a ‘‘second look,’’ i.e., a meaningful opportu-
    nity for the juvenile offender to obtain release based
    on demonstrated maturity and rehabilitation. 
    Id., 39–40. In
    his certified appeal to this court, the defendant
    contends that the Appellate Court majority was incor-
    rect as a matter of law and fact. Specifically, he con-
    tends that the sentencing procedure and the sentence
    itself failed to conform to the dictates of Miller and
    Graham. For the reasons that follow, we agree that the
    defendant is entitled to a new sentencing proceeding
    that follows the dictates of Miller.
    I
    THE UNITED STATES SUPREME COURT’S TRILOGY
    The eighth amendment to the United States constitu-
    tion provides: ‘‘Excessive bail shall not be required,
    nor excessive fines imposed, nor cruel and unusual
    punishments inflicted.’’ This provision is applicable to
    the states through the fourteenth amendment. See Fur-
    man v. Georgia, 
    408 U.S. 238
    , 239, 
    92 S. Ct. 2726
    , 33 L.
    Ed. 2d 346 (1972). ‘‘[T]he [e]ighth [a]mendment guaran-
    tees individuals the right not to be subjected to exces-
    sive sanctions. The right flows from the basic precept
    of justice that punishment for crime should be gradua-
    ted and proportioned to [the] offense.’’ (Internal quota-
    tion marks omitted.) Roper v. 
    Simmons, supra
    , 
    543 U.S. 560
    .
    Although the unique aspects of adolescence had long
    been recognized in the Supreme Court’s jurisprudence,3
    it was not until the trilogy of Roper, Graham, and Miller
    that the court held that youth and its attendant charac-
    teristics have constitutional significance for purposes
    of assessing proportionate punishment under the eighth
    amendment. Cf. Stanford v. Kentucky, 
    492 U.S. 361
    ,
    382–405, 
    109 S. Ct. 2969
    , 
    106 L. Ed. 2d 306
    (1989) (Bren-
    nan, J., dissenting) (criticizing majority’s failure to con-
    sider principle of proportionate punishment in
    determining that death penalty may be applied to per-
    sons who committed capital crime between ages of
    sixteen and eighteen), overruled in part by Roper v.
    Simmons, 
    543 U.S. 551
    , 574, 
    125 S. Ct. 1183
    , 161 L.
    Ed. 2d 1 (2005). Because Roper and Graham lay the
    foundation for Miller, we begin with a brief overview
    of those cases.
    A
    Roper
    Christopher Simmons was seventeen years old when
    he planned and carried out the brutal murder of a
    stranger. Roper v. 
    Simmons, supra
    , 
    543 U.S. 556
    –57.
    The state of Missouri challenged the Missouri Supreme
    Court’s decision setting aside Simmons’ sentence of
    death and resentencing him to life imprisonment with-
    out eligibility for parole due to his age when he commit-
    ted the offense. 
    Id., 559–60. The
    United States Supreme
    Court agreed with the state court that the execution of
    a person who was between the ages of sixteen and
    eighteen when he committed a capital crime constituted
    disproportionate punishment in violation of the eighth
    amendment.4 
    Id., 555, 568;
    see Thompson v. Oklahoma,
    
    487 U.S. 815
    , 838, 
    108 S. Ct. 2687
    , 
    101 L. Ed. 2d 702
    (1988) (plurality) (concluding that execution of person
    who was under age of sixteen at time offense was com-
    mitted violates eighth and fourteenth amendments).
    In reaching its conclusion, the court relied upon its
    prior case law recognizing the unique characteristics of
    juveniles and scientific evidence regarding differences
    between adult and juvenile psychological development
    that explained these characteristics. Roper v. 
    Simmons, supra
    , 
    543 U.S. 569
    –71. This evidence demonstrated
    that a juvenile’s less developed character, maturity and
    impulse control affect decision making and apprecia-
    tion of risk, and that a juvenile’s poor decisions did not
    necessarily portend how the offender might act upon
    achieving maturation. 
    Id., 569–70. Because
    of a juve-
    nile’s diminished culpability, the court concluded that
    the two penological justifications for the death penalty,
    retribution and deterrence, applied with lesser force to
    them than to adults. 
    Id., 571. The
    court suggested that,
    ‘‘[t]o the extent the juvenile death penalty might have
    residual deterrent effect, it is worth noting that the
    punishment of life imprisonment without the possibility
    of parole is itself a severe sanction, in particular for a
    young person.’’ 
    Id., 572. The
    court ultimately determined that a categorical
    ban on executing juvenile offenders was required. 
    Id., 573. It
    reasoned that ‘‘[a]n unacceptable likelihood
    exists that the brutality or cold-blooded nature of any
    particular crime would overpower mitigating argu-
    ments based on youth as a matter of course, even where
    the juvenile offender’s objective immaturity, vulnerabil-
    ity, and lack of true depravity should require a sentence
    less severe than death.’’ 
    Id. In response
    to an argument
    that a rare case might exist wherein the juvenile demon-
    strated sufficient maturity and depravity to warrant a
    death sentence, the court pointed out that ‘‘[i]t is diffi-
    cult even for expert psychologists to differentiate
    between the juvenile offender whose crime reflects
    unfortunate yet transient immaturity, and the rare juve-
    nile offender whose crime reflects irreparable corrup-
    tion.’’ 
    Id. Accordingly, the
    court held that ‘‘[w]hen a
    juvenile offender commits a heinous crime, the [s]tate
    can exact forfeiture of some of the most basic liberties,
    but the [s]tate cannot extinguish his life and his poten-
    tial to attain a mature understanding of his own human-
    ity.’’ (Internal quotation marks omitted.) 
    Id., 573–74. B
                             Graham
    Five years later, the court considered whether a sen-
    tence of life imprisonment without parole is dispropor-
    tionate punishment for a juvenile offender who
    committed a nonhomicide crime. Graham v. 
    Florida, supra
    , 
    560 U.S. 52
    –53, 59. Terrance Jamar Graham was
    seventeen years old when he violated his probation on
    charges including armed burglary by committing other
    crimes six months later. 
    Id., 53–55. Reasoning
    that the
    defendant had an escalating pattern of criminal con-
    duct, the trial court imposed the maximum sentence
    permitted by law—life imprisonment. 
    Id., 57. Parole
    was unavailable under state law. 
    Id. The First
    District
    Court of Appeal of Florida concluded that Graham’s
    sentence was not grossly disproportionate to his
    crimes. 
    Id., 58. The
    United States Supreme Court cate-
    gorically rejected that conclusion. 
    Id., 67–75. The
    court’s reasoning in Graham largely expanded
    upon the analytic blueprint of Roper. Graham relied
    on further developments in psychology and brain sci-
    ence that supported the foundational determination in
    Roper regarding the lesser culpability of juvenile offend-
    ers. 
    Id., 68. Graham
    analogized the severity of a sen-
    tence of life without the possibility of parole for a
    juvenile offender to capital punishment: ‘‘[F]or a juve-
    nile defendant, this sentence 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 convict], he
    will remain in prison for the rest of his days.’’ (Internal
    quotation marks omitted.) 
    Id., 70. The
    court reasoned
    that a life sentence without parole, the most severe
    punishment permitted by law for a juvenile offender,
    was particularly disproportionate in light of prior cases
    ‘‘recogniz[ing] that defendants who do not kill, intend
    to kill, or foresee that life will be taken are categorically
    less deserving of the most serious forms of punishments
    than are murderers.’’ 
    Id., 69. Thus,
    the juvenile nonhomi-
    cide offender has a ‘‘twice diminished moral culpability’’
    when compared to an adult murderer. 
    Id. In addition
    to the legitimate penological goals of retri-
    bution and deterrence that Roper had found lacking in
    applying the death penalty to juvenile offenders, the
    court found that other legitimate goals for punish-
    ment—rehabilitation and incapacitation—also were
    rendered largely ineffective due to the unique character-
    istics of juvenile offenders. 
    Id., 71–74. Like
    Roper, Gra-
    ham questioned the sentencer’s ability to predict
    whether a juvenile would be a risk to society for the
    rest of his life in light of his greater capacity for change
    than an adult offender. The court noted that, ‘‘[e]ven if
    the [s]tate’s judgment that Graham was incorrigible
    were later corroborated by prison misbehavior or fail-
    ure to mature, the sentence was still disproportionate
    because that judgment was made at the outset. A life
    without parole sentence improperly denies the juvenile
    offender a chance to demonstrate growth and matu-
    rity.’’ 
    Id., 73. In
    light of these considerations, the court held: ‘‘A
    [s]tate is not required to guarantee eventual freedom to
    a juvenile offender convicted of a nonhomicide crime.
    What the [s]tate must do, however, is give defendants
    like Graham some meaningful opportunity to obtain
    release based on demonstrated maturity and rehabilita-
    tion. . . . The [e]ighth [a]mendment does not foreclose
    the possibility that persons convicted of nonhomicide
    crimes committed before adulthood will remain behind
    bars for life. It does forbid [s]tates from making the
    judgment at the outset that those offenders never will
    be fit to reenter society.’’ 
    Id., 75. C
                              Miller
    Roper and Graham followed a strand of the court’s
    proportionality jurisprudence under which the court
    adopted categorical bans on sentencing practices for
    particular groups of offenders ‘‘based on mismatches
    between the culpability of [that] class of offenders and
    the severity of a penalty.’’ Miller v. 
    Alabama, supra
    ,
    
    132 S. Ct. 2463
    . Another strand of proportionality juris-
    prudence, applied in death penalty cases, required indi-
    vidualized sentencing procedures wherein the
    mitigating characteristics of a defendant and the details
    of the offense must be considered. See, e.g., Eddings
    v. Oklahoma, 
    455 U.S. 104
    , 115, 
    102 S. Ct. 869
    , 
    71 L. Ed. 2d
    1 (1982) (evidence of violent family background and
    emotional disturbance is ‘‘particularly relevant’’ mitigat-
    ing circumstance that must be considered before impos-
    ing death penalty on sixteen year old). In light of
    Graham’s analogy between life without parole and the
    death penalty, the court in Miller concluded that both
    strands of jurisprudence were implicated in eighth
    amendment challenges by two offenders who were four-
    teen years old when they committed murder, an offense
    for which state law mandated life without parole. Miller
    v. 
    Alabama, supra
    , 2460, 2464. The court concluded
    that such a scheme violates the eighth amendment
    because it ‘‘prevents those meting out punishment from
    considering a juvenile’s ‘lessened culpability’ and
    greater ‘capacity for change,’ Graham v. Florida,
    [supra, 
    560 U.S. 48
    ], and runs afoul of our cases’ require-
    ment of individualized sentencing for defendants facing
    the most serious penalties.’’ Miller v. 
    Alabama, supra
    , 2460.
    The court explained that ‘‘Roper and Graham estab-
    lish that children are constitutionally different from
    adults for purposes of sentencing. . . . Those cases
    relied on three significant gaps between juveniles and
    adults. First, children have a lack of maturity and an
    underdeveloped sense of responsibility, leading to reck-
    lessness, impulsivity, and heedless risk-taking. . . .
    Second, children are more vulnerable . . . to negative
    influences and outside pressures, including from their
    family and peers; they have limited contro[l] over their
    own environment and lack the ability to extricate them-
    selves from horrific, crime-producing settings. . . .
    And third, a child’s character is not as well formed as
    an adult’s; his traits are less fixed and his actions less
    likely to be evidence of irretrievabl[e] deprav[ity].’’
    (Citations omitted; internal quotation marks omitted.)
    
    Id., 2464. The
    court emphasized that these two decisions rested
    not only on common sense, but also on science and
    social science: ‘‘In Roper, we cited studies showing that
    [o]nly a relatively small proportion of adolescents who
    engage in illegal activity develop entrenched patterns
    of problem behavior. . . . And in Graham, we noted
    that developments in psychology and brain science con-
    tinue to show fundamental differences between juvenile
    and adult minds—for example, in parts of the brain
    involved in behavior control. . . . We reasoned that
    those findings—of transient rashness, proclivity for
    risk, and inability to assess consequences—both les-
    sened a child’s moral culpability and enhanced the pros-
    pect that, as the years go by and neurological
    development occurs, his deficiencies will be reformed.’’
    (Citations omitted; footnote omitted; internal quotation
    marks omitted.) 
    Id., 2464–65. Miller
    further under-
    scored the connection between these findings and the
    diminished penological justifications for imposing the
    harshest sentences on juvenile offenders ‘‘even when
    they commit terrible crimes.’’ 
    Id., 2465. Despite
    the distinction the court in Graham drew
    between homicide and nonhomicide offenders, the
    court in Miller determined that the reasoning of Gra-
    ham applied with equal force to any juvenile life sen-
    tence without parole: ‘‘[N]one of what [Graham] said
    about children . . . is crime-specific. . . . Graham’s
    reasoning implicates any life-without-parole sentence
    imposed on a juvenile, even as its categorical bar relates
    only to nonhomicide offenses. Most fundamentally,
    Graham insists that youth matters in determining the
    appropriateness of a lifetime of incarceration without
    the possibility of parole. . . . An offender’s age, we
    made clear in Graham, is relevant to the [e]ighth
    [a]mendment, and so criminal procedure laws that fail
    to take defendants’ youthfulness into account at all
    would be flawed.’’ (Citation omitted; internal quotation
    marks omitted.) 
    Id., 2465–66. A
    mandatory sentence of life without parole for a
    juvenile offender, however, contravenes this reasoning
    insofar as it ‘‘precludes consideration of his chronologi-
    cal age and its hallmark features—among them, imma-
    turity, impetuosity, and failure to appreciate risks and
    consequences. It prevents taking into account the fam-
    ily and home environment that surrounds him—and
    from which he cannot usually extricate himself—no
    matter how brutal or dysfunctional. It neglects the cir-
    cumstances of the homicide offense, including the
    extent of his participation in the conduct and the way
    familial and peer pressures may have affected him.
    Indeed, it ignores that he might have been charged and
    convicted of a lesser offense if not for incompetencies
    associated with youth—for example, his inability to
    deal with police officers or prosecutors (including on
    a plea agreement) or his incapacity to assist his own
    attorneys. . . . And finally, this mandatory punish-
    ment disregards the possibility of rehabilitation even
    when the circumstances most suggest it.’’ (Citations
    omitted.) 
    Id., 2468. Perhaps
    most significantly for our purposes, the court
    in Miller summarized its holding as follows: ‘‘[T]he
    [e]ighth [a]mendment forbids a sentencing scheme that
    mandates life in prison without possibility of parole for
    juvenile offenders. . . . By making youth (and all that
    accompanies it) irrelevant to imposition of that harshest
    prison sentence, such a scheme poses too great a risk
    of disproportionate punishment. Because that holding
    is sufficient to decide these cases, we do not consider
    [the petitioners’] alternative argument that the [e]ighth
    [a]mendment requires a categorical bar on life without
    parole for juveniles, or at least for those [fourteen] and
    younger. But given all we have said in Roper, Graham,
    and this decision about children’s diminished culpabil-
    ity and heightened capacity for change, we think appro-
    priate 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 juve-
    nile offender whose crime reflects irreparable corrup-
    tion. . . . 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 differ-
    ent, and how those differences counsel against irrevoca-
    bly sentencing them to a lifetime in prison.’’ (Citations

    Id., 2469. II
        IMPORT OF MILLER FOR DISCRETIONARY
    SENTENCING SCHEMES
    The parties dispute whether Miller extends beyond
    mandatory sentencing schemes. The state reads Miller
    narrowly in light of its emphasis on the defects inherent
    in a mandatory scheme. The defendant reads Miller
    broadly in light of its rationale. We conclude that the
    state’s view of Miller is unduly restrictive. We read the
    import of Miller as impacting two aspects of sentencing:
    (1) that a lesser sentence than life without parole must
    be available for a juvenile offender; and (2) that the
    sentencer must consider age related evidence as mitiga-
    tion when deciding whether to irrevocably sentence
    juvenile offenders to a lifetime in prison. Accordingly,
    for the reasons set forth subsequently in this opinion,
    we hold that the dictates set forth in Miller may be
    violated even when the sentencing authority has discre-
    tion to impose a lesser sentence than life without parole
    if it fails to give due weight to evidence that Miller
    deemed constitutionally significant before determining
    that such a severe punishment is appropriate.
    We begin by acknowledging that Miller is replete
    with references to ‘‘mandatory’’ life without parole and
    like terms. Nonetheless, the Supreme Court’s incremen-
    tal approach to assessing the proportionality of juvenile
    punishment counsels against viewing these cases
    through an unduly myopic lens. Roper contained lan-
    guage indicating that life imprisonment without parole
    would be a constitutionally permissible punishment for
    a juvenile offender when striking down the juvenile
    death penalty. See Roper v. 
    Simmons, supra
    , 
    543 U.S. 572
    ; see also State v. Allen, 
    289 Conn. 550
    , 581–82, 
    958 A.2d 1214
    (2008) (agreeing with authority from other
    jurisdictions concluding that life sentence without
    parole for juvenile offender is permissible under Roper).
    Yet, the court in Graham relied on the reasoning in
    Roper to conclude that imposing such a punishment on
    juvenile nonhomicide offenders violates eighth amend-
    ment proportionality principles. See Graham v. Flor-
    
    ida, supra
    , 
    560 U.S. 68
    , 71–73. Similarly, Graham
    contained language distinguishing between nonhomi-
    cide and homicide offenses when striking down life
    sentences without parole for nonhomicide offenders.
    See 
    id., 69. Yet,
    the court in Miller underscored that
    nothing Graham had noted about juvenile characteris-
    tics was crime specific when the court extended the
    reasoning of Graham to preclude mandatory life sen-
    tences without parole. Miller v. 
    Alabama, supra
    , 132 S.
    Ct. 2465. Indeed, while carefully limiting its holding to
    mandatory sentences, Miller expressly reserved judg-
    ment on whether all juvenile life sentences without
    parole would run afoul of the eighth amendment. 
    Id. Accordingly, the
    court’s approach in this arena counsels
    us to examine the logical implications of its reasoning
    in these decisions.
    Three aspects of Miller, when read in light of Roper
    and Graham, demonstrate that the decision logically
    reaches beyond its core holding. First, Roper, Graham
    and Miller emphasized their reliance on an ever growing
    body of authoritative evidence establishing constitu-
    tionally significant differences between adult and juve-
    nile brains. See 
    id., 2464–65 n.5
    (‘‘[t]he evidence
    presented to us in these cases indicates that the science
    and social science supporting Roper’s and Graham’s
    conclusions have become even stronger’’). In reliance
    on this evidence, the court in Miller explained that
    ‘‘[m]ost fundamentally, Graham insists that youth mat-
    ters in determining the appropriateness of a lifetime of
    incarceration without the possibility of parole.’’
    (Emphasis added.) 
    Id., 2465. Consistent
    with that dic-
    tate, the court in Miller held that it would ‘‘require
    [the sentencer] to take into account how children are
    different, and how those differences counsel against
    irrevocably sentencing them to a lifetime in prison.’’
    (Emphasis added.) 
    Id., 2469. This
    mandate logically
    would extend to a discretionary sentencing scheme.
    Second, in Miller, the court expressed its confidence
    that, once the sentencing authority considers the miti-
    gating factors of the offender’s youth and its attendant
    circumstances, ‘‘appropriate occasions for sentencing
    juveniles to this harshest possible penalty will be
    uncommon.’’ 
    Id. This language
    suggests that the mitigat-
    ing factors of youth establish, in effect, a presumption
    against imposing a life sentence without parole on a
    juvenile offender that must be overcome by evidence
    of unusual circumstances. This presumption logically
    would extend to discretionary schemes that authorize
    such a sentence.
    Third, Miller and Graham analogized the harshness
    of a life sentence without parole for a juvenile to the
    death penalty. See 
    id., 2466; Graham
    v. 
    Florida, supra
    ,
    
    560 U.S. 69
    –71. This penalty is no less harsh if imposed
    pursuant to an exercise of discretion.
    We also find instructive the approach of other juris-
    dictions to the question of what Miller demands.
    Although there is a split of authority among courts that
    have considered whether Miller applies to discretionary
    sentencing schemes,5 we find most telling the response
    of those jurisdictions whose mandatory sentencing
    schemes were rendered unconstitutional by Miller.
    Many of these jurisdictions have reformed their sen-
    tencing procedures to require the sentencing court to
    consider those youth related factors that Miller identi-
    fied as constitutionally relevant mitigation. See, e.g.,
    Mich. Comp. Laws § 769.25 (6) (2014) (‘‘If the prosecut-
    ing attorney files a motion [seeking a sentence of life
    imprisonment without parole], the court shall conduct
    a hearing on the motion as part of the sentencing pro-
    cess. At the hearing, the trial court shall consider the
    factors listed in Miller [v.] Alabama, [supra, 
    132 S. Ct. 2455
    ], and may consider any other criteria relevant to
    its decision, including the individual’s record while
    incarcerated.’’); Neb. Rev. Stat. § 28-105.02 (2) (Supp.
    2013) (requiring court to consider juvenile offender’s
    age and numerous other youth related factors); Wash.
    Rev. Code § 10.95.030 (3) (b) (2014) (‘‘[i]n setting a
    minimum term, the court must take into account miti-
    gating factors that account for the diminished culpabil-
    ity of youth as provided in Miller v. Alabama, [supra,
    2455] including, but not limited to, the age of the individ-
    ual, the youth’s childhood and life experience, the
    degree of responsibility the youth was capable of exer-
    cising, and the youth’s chances of becoming rehabili-
    tated’’); W. Va. Code Ann. § 61-11-23 (c) (LexisNexis
    2014) (requiring court to consider juvenile offender’s
    age and numerous other youth related factors); but
    see, e.g., State v. Ali, 
    855 N.W.2d 235
    , 257 (Minn. 2014)
    (sentencer must hold evidentiary hearing to consider
    Miller mitigation factors ‘‘upon request and with the
    assistance of counsel’’). In addition, several jurisdic-
    tions have required the sentencing court to state on the
    record the basis for a conclusion that life imprisonment
    without parole is an appropriate sentence, despite miti-
    gating factors relating to the offender’s youth. See, e.g.,
    Mich. Comp. Laws § 769.25 (7) (2014); N.C. Gen. Stat.
    Ann. § 15A-1340.19C (a) (LexisNexis 2013); 18 Pa. Cons.
    Stat. Ann. § 1102.1 (d) (7) (West Cum. Supp. 2014); see
    also Sen v. State, 
    301 P.3d 106
    , 127 (Wyo. 2013) (‘‘in
    exercising its discretion with regard to a determination
    as to parole eligibility, the district court must set forth
    specific findings supporting a distinction between ‘the
    juvenile offender whose crime reflects unfortunate yet
    transient immaturity, and the rare juvenile offender
    whose crime reflects irreparable corruption’ ’’).
    For the foregoing reasons, we conclude that Miller
    does not stand solely for the proposition that the eighth
    amendment demands that the sentencer have discretion
    to impose a lesser punishment than life without parole
    on a juvenile homicide offender. Rather, Miller logically
    indicates that, if a sentencing scheme permits the impo-
    sition of that punishment on a juvenile homicide
    offender, the trial court must consider the offender’s
    ‘‘chronological age and its hallmark features’’ as mitigat-
    ing against such a severe sentence. Miller v. 
    Alabama, supra
    , 
    132 S. Ct. 2468
    . As the court in Miller explained,
    those features include: ‘‘immaturity, impetuosity, and
    failure to appreciate risks and consequences’’; the
    offender’s ‘‘family and home environment’’ and the
    offender’s inability to extricate himself from that envi-
    ronment; ‘‘the circumstances of the homicide offense,
    including the extent of [the offender’s] participation in
    the conduct and the way familial and peer pressures
    may have affected him’’; the offender’s ‘‘inability to deal
    with police officers or prosecutors (including on a plea
    agreement) or his incapacity to assist his own attor-
    neys’’; and ‘‘the possibility of rehabilitation . . . .’’6 
    Id. We note
    that, following the decision in Miller, our
    state’s presentence report has incorporated these fac-
    tors as required subjects of investigation and reporting.
    See State of Connecticut, Judicial Branch, Court Sup-
    port Services Division, ‘‘Policies and Procedures,’’ Pol-
    icy 4.31, effective August 15, 2013, pp. 11, 14–22. In
    addition to these factors specific to the individual juve-
    nile offender, the report must ‘‘note any scientific and
    psychological evidence showing the differences
    between a child’s (a person under the age of [eighteen])
    brain development and an adult’s brain development
    . . . .’’ 
    Id., p. 22.
    Although it appears from the report
    form that the Court Support Services Division intends
    to provide courts with information on this subject at
    some point in the future, in the interim, we direct our
    trial courts to the evidence that Roper, Graham, and
    Miller credited as authoritative on this subject. To con-
    form to Miller’s mandate and our rules of practice; see
    Practice Book § 43-10; the record must reflect that the
    trial court has considered and given due mitigating
    weight to these factors in determining a proportion-
    ate punishment.
    III
    APPLICATION OF MILLER TO THE PRESENT CASE
    By statute and the rules of practice, our trial courts
    must consider the information in the presentence report
    before imposing sentence. See General Statutes § 54-
    91a (a); Practice Book §§ 43-3 and 43-10. In 2009, when
    the court imposed sentence in the present case, the
    presentence report did not require information specific
    to juvenile offenders. The report generically required
    information regarding, inter alia, ‘‘the circumstances of
    the offense . . . and the criminal record, social history
    and present condition of the defendant.’’ General Stat-
    utes § 54-91a (c). The court was required at that time,
    and still is today, to hear from all parties and to state
    on the record the reasons for the sentence imposed.
    Practice Book § 43-10 (6). Accordingly, nothing in our
    sentencing scheme specifically required the trial court
    in the present case to consider, let alone give mitigating
    weight to, the defendant’s age at the time of the offense
    or the hallmarks of youth.
    Nor does the record in the present case reflect, as
    the state contends, that the trial court adequately con-
    sidered the factors identified in Miller. In the entire
    sentencing proceeding, only defense counsel made an
    oblique reference to age. Defense counsel commented,
    ‘‘[y]ou can see that, obviously, [the defendant is] a young
    man’’—a remark that appears to refer to the defendant’s
    age at the time of sentencing—and asked the court to
    consider the defendant’s age. The defendant was then
    almost twenty years old. Although the undated presen-
    tence report reflected the defendant’s date of birth and
    age (nineteen) at the time the report was prepared, it
    did not address the defendant’s immaturity, impetuos-
    ity, and failure to appreciate risks and consequences.
    Nor did it address the science that establishes such
    factors as generally applicable.
    The main thrust of the court’s comments at sentenc-
    ing related to the innocence of the victims and the
    choice made by the defendant to commit these sense-
    less crimes. Before imposing a sentence under which
    the defendant would undoubtedly die in prison, the
    court characterized the presentence report as reflecting
    a life that was ‘‘pretty unremarkable.’’ The court made
    no mention of facts in the presentence report that might
    reflect immaturity, impetuosity, and failure to appreci-
    ate risks and consequences. For example, there was no
    mention of the fact that the defendant was reported to
    have a five year old child, which meant that he had
    fathered the child at or before the age of fourteen.
    Instead, the court noted: ‘‘I have very little sense of the
    type of person [the defendant] is except for what he
    did on this day and for that that’s what I have to sentence
    him for.’’ Accordingly, the record does not clearly
    reflect that the court considered and gave mitigating
    weight to the defendant’s youth and its hallmark fea-
    tures when considering whether to impose the func-
    tional equivalent to life imprisonment without parole.
    Therefore, the defendant is entitled to a new sentenc-
    ing proceeding that conforms to the dictates of Miller.
    Both the defendant and the state are free to present
    additional evidence at this new proceeding.
    IV
    WHETHER THE DEFENDANT’S SENTENCE
    VIOLATED GRAHAM
    As we previously explained, Graham precludes the
    sentencer from determining at the outset that a juvenile
    nonhomicide offender is beyond rehabilitation, thus
    requiring that such offenders be afforded a meaningful
    opportunity to obtain release based on demonstrated
    maturity and rehabilitation if sentenced to life imprison-
    ment. Graham v. 
    Florida, supra
    , 
    560 U.S. 75
    . The court
    left it to the states ‘‘to explore the means and mecha-
    nisms for compliance’’; id.; with this so-called ‘‘second
    look’’ opportunity. State v. 
    Riley, supra
    , 
    140 Conn. App. 22
    (Borden, J., dissenting); State v. Null, 
    836 N.W.2d 41
    , 67–68 (Iowa 2013). Although Graham was limited
    to nonhomicide offenses, the defendant in the present
    case relied on the fact that Miller underscored that
    Graham’s rationale was not crime specific; see Miller
    v. 
    Alabama, supra
    , 
    132 S. Ct. 2465
    ; as support for the
    view that this second look opportunity extends to juve-
    nile homicide offenders. Two considerations persuade
    us that it would be inappropriate for us to resolve this
    question at this juncture.
    This court has recognized that ‘‘the fixing of prison
    terms for specific crimes involves a substantive peno-
    logical judgment that, as a general matter, is properly
    within the province of legislatures, not courts.’’ (Inter-
    nal quotation marks omitted.) State v. Higgins, 
    265 Conn. 35
    , 63, 
    826 A.2d 1126
    (2003); accord State v.
    Heinemann, 
    282 Conn. 281
    , 311, 
    920 A.2d 278
    (2007)
    (‘‘[w]e defer to the broad authority that legislatures
    possess in determining the types and limits of punish-
    ment for crimes’’); State v. Darden, 
    171 Conn. 677
    , 679–
    80, 
    372 A.2d 99
    (1976) (‘‘the constitution assigns to the
    legislature the power to enact laws defining crimes and
    fixing the degree and method of punishment and to the
    judiciary the power to try offenses under these laws
    and impose punishment within the limits and according
    to the methods therein provided’’). Staying our hand
    in deference to a coordinate branch of government is
    particularly appropriate in the present case. In the wake
    of Miller and Graham, the legislature directed the Con-
    necticut Sentencing Commission (commission) to make
    recommendations regarding reforms for the sentencing
    of juvenile offenders. Following the commission’s rec-
    ommendation, comprehensive bills were drafted relat-
    ing both to the consideration of youth, and its attendant
    characteristics, as a mitigating factor and to the provi-
    sion of a second look opportunity upon imposition of
    sentences in excess of ten years. See Substitute Senate
    Bill No. 1062, 2013 Sess.; Substitute House Bill No. 6581,
    2013 Sess.; Substitute House Bill No. 5221, 2014 Sess.
    For reasons that are not apparent, in successive years,
    the bills were tabled in the Senate and were not acted
    upon before the expiration of the legislative sessions
    in which they were raised, thus requiring the legislature
    to take up the issue anew in the next session. In light
    of our decision in the present case, there is every reason
    to believe that the legislature will take definitive action
    regarding these issues with all deliberate speed. There-
    fore, for now, we will not provide the ‘‘means and mech-
    anisms for compliance’’ with the dictates of Graham.
    See Graham v. 
    Florida, supra
    , 
    560 U.S. 75
    .
    In addition, concerns of ripeness counsel against
    reaching this issue. The defendant is entitled to a new
    sentencing proceeding. It is reasonably possible that
    the trial court will impose a less severe sentence than
    what is functionally life imprisonment without parole
    upon due consideration of the defendant’s age at the
    time of the offenses and the hallmark characteristics
    of youth as they bear on his conduct. Because the defen-
    dant’s claim rests on the factual predicate of a sentence
    that is the functional equivalent to life imprisonment
    without parole, it may be unnecessary for us to decide
    whether the defendant is entitled to a second look. See
    Chapman Lumber, Inc. v. Tager, 
    288 Conn. 69
    , 86–87,
    
    952 A.2d 1
    (2008) (‘‘in determining whether a case is
    ripe, [the] court must be satisfied that the case before
    [it] does not present a hypothetical injury or a claim
    contingent upon some event that has not and indeed
    may never transpire’’ [internal quotation marks omit-
    ted]). Indeed, at oral argument before this court, the
    defendant conceded that we need not reach this claim.
    The judgment of the Appellate Court is reversed and
    the case is remanded to that court with direction to
    reverse the judgment of the trial court only with respect
    to the defendant’s sentence and to remand the case to
    that court for a new sentencing proceeding consistent
    with this opinion.
    In this opinion ROGERS, C. J., and PALMER, EVE-
    LEIGH and ROBINSON, Js., concurred.
    1
    We use the term juvenile offenders to refer to persons who committed
    a crime when they were younger than eighteen years of age.
    2
    The Penal Code defines ‘‘life imprisonment’’ as a definite sentence of
    sixty years, unless a sentence of life imprisonment without the possibility
    of release is imposed, in which case the term means imprisonment for the
    remainder of the defendant’s natural life. See General Statutes § 53a-35b.
    The defendant was sentenced to sixty years on count one for murder; twenty
    years on count two for attempt to commit murder, consecutive to the first
    count; twenty years on count three for attempt to commit murder, consecu-
    tive to the first two counts; twenty years on count four for assault with a
    firearm, concurrent to the second count; twenty years on count five for
    assault in the first degree with a firearm, concurrent to the third count; and
    twenty years on count six for conspiracy to commit murder, concurrent to
    the previous counts.
    The defendant contends that the parole statute is ambiguous as to whether
    he is per se ineligible for parole because of his murder conviction; see
    General Statutes § 54-125a (b) (1) (E); or whether he is eligible after complet-
    ing the sentence for that offense and 85 percent of his sentences for the
    nonhomicide offenses. See General Statutes § 54-125a (b) (2) (B). Even
    under the interpretation more favorable to him, the defendant would not
    be eligible for release until he has served ninety-four years imprisonment.

    In Roper and Graham, the court first determined that there was a national
    consensus against the punishment at issue as applied to juvenile offenders
    before examining the proportionality of the punishment. See Roper v. Sim-
    
    mons, supra

    We note that, although some cases simply consider whether Miller is
    violated if the sentencer has discretion to impose a sentence of life without
    parole, others also consider whether the sentencer was required to consider
    the offender’s youth as a mitigating factor when exercising that discretion.
    Some courts have concluded that Miller only applies to sentences of manda-
    tory life without parole yet have made a point of concluding that the discre-
    tionary procedure conformed to Miller because the trial court considered
    the offender’s youth. Thus, we conclude that there is no clear consensus
    on this issue. Compare State v. Agboghidi, Docket No. 2 CA-CR 2013-0497-
    PR, 
    2014 WL 1572742

    life without parole on a juvenile homicide offender when the penalty is
    discretionary and when the sentencing court’s discretion is properly exer-

    (2014) (The court initially stated that ‘‘Ohio’s sentencing scheme
    does not fall afoul of Miller, because the sentence of life without parole is
    discretionary’’ but later stated: ‘‘Because the trial court did not separately
    mention that [the defendant] was a juvenile when he committed the offense,
    we cannot be sure how the trial court applied this factor. Although Miller
    does not require that specific findings be made on the record, it does mandate
    that a trial court consider as mitigating the offender’s youth and its attendant
    characteristics before imposing a sentence of life without parole.’’ [Emphasis
