  •            DOMINIC PEREZ v. COMMISSIONER
    OF CORRECTION
    (SC 19855)
    Rogers, C. J., and Palmer, Eveleigh, McDonald, Espinosa,
    Robinson and Vertefeuille, Js.*
    Syllabus
    Pursuant to statute ([Rev. to 2009] § 54-125a [b] [2], as amended by P.A. 10-
    36), a person convicted of an offense involving the use of physical force
    against another person shall be ineligible for parole until he has served
    not less than 85 percent of the definite sentence imposed.
    Pursuant further to statute ([Rev. to 2009] § 54-125a [e]), the Board of
    Pardons and Paroles shall hold a hearing to determine the suitability
    for parole of any person whose eligibility for such parole is subject to
    the provisions of § 54-125a (b) (2) upon his completion of 85 percent
    of his definite or aggregate sentence.
    The petitioner, who had been convicted of manslaughter in the first degree
    and carrying a pistol without a permit for conduct occurring in 2010,
    filed a petition for a writ of habeas corpus, claiming, inter alia, that
    amendments in 2013 (P.A. 13-3 and P.A. 13-247) to § 54-125a violated
    his constitutional rights to due process and equal protection, the ex
    post facto clause of the United States constitution, and the separation
    of powers doctrine. In 2011, while the petitioner’s criminal case was
    pending, the legislature enacted a statute (§ 18-98e) pursuant to which
    the respondent, the Commissioner of Correction, was vested with discre-
    tion to award risk reduction credit toward the reduction of an inmate’s
    sentence, up to five days per month, for positive conduct. The legislature
    also amended § 54-125a (b) (2) and (e) in 2011 to provide that risk
    reduction credit earned under § 18-98e was to be applied to an inmate’s
    definite sentence to advance the inmate’s end of sentence date, and
    rendered that inmate eligible for a parole hearing after he had served
    85 percent of that reduced sentence. After the petitioner had been
    sentenced, the legislature again amended § 54-125a in 2013, eliminating
    the language that permitted the parole eligibility date to be advanced
    by the application of earned risk reduction credit, and eliminating the
    requirement that the Board of Pardons and Paroles ‘‘shall’’ hold a parole
    hearing after an inmate has completed 85 percent of his sentence. Under
    the 2013 amendments, which became effective July 1, 2013, any risk
    reduction credit earned by an inmate, and not subsequently revoked by
    the respondent, would still be applied to reduce an inmate’s sentence
    but would not be applied to advance his parole eligibility date, and,
    once that eligibility date arises, the parole board may decline to hold a
    hearing. In his habeas petition, the petitioner challenged the application
    of the 2013 amendments to the calculation of his parole eligibility date
    and to his right to a hearing on his suitability for parole, alleging that
    he had already been awarded risk reduction credit by the respondent,
    and that, prior to the 2013 amendments, the respondent had applied
    that credit to advance his parole eligibility date. The habeas court granted
    the respondent’s motion to dismiss all counts of the habeas petition,
    concluding that all of the petitioner’s claims failed given the speculative
    nature of earned risk reduction credit and the respondent’s discretion
    to award and revoke such credit, and concluding that, because the
    petition failed to state a claim on which habeas relief could be granted,
    the court lacked subject matter jurisdiction over the petition. The habeas
    court thereafter rendered judgment dismissing the petition, from which
    the petitioner, on the granting of certification, appealed. Held that the
    habeas court properly dismissed the petition for a writ of habeas corpus,
    this court having determined that, although the habeas court improperly
    dismissed many of the petitioner’s claims solely on the basis of the
    speculative nature of earned risk reduction credit, the habeas court
    lacked jurisdiction over all of the petitioner’s claims:
    1. The petitioner could not prevail on his claims that the 2013 amendments
    to § 54-125a that eliminated the application of prior earned risk reduction
    credit to advance his parole eligibility date and the mandate that a parole
    hearing be held violated his right to due process under the federal and
    state constitutions and his right to personal liberty pursuant to the state
    constitution: the petitioner failed to establish a vested liberty interest
    in either the granting of parole, the timing of when parole is granted or
    the procedure by which the parole board exercises its discretion to
    award or deny parole, as the granting of parole is within the discretion
    of the parole board, and the petitioner also failed to establish a vested
    right in the application of the risk reduction credit previously granted
    to advance his parole eligibility date, as that credit was subject to
    revocation at the discretion of the respondent for good cause; moreover,
    the monthly parole eligibility calculation that the respondent provided
    to the petitioner was simply an informational tool to allow the respon-
    dent and the petitioner to estimate his parole eligibility date, provided
    the respondent did not rescind any of the earned credit.
    2. The petitioner’s claim that the 2013 amendments to the parole hearing
    and eligibility provisions of § 54-125a violated the ex post facto clause
    of the federal constitution was not cognizable, as the parole hearing
    provision did not increase the petitioner’s overall sentence, alter his
    initial parole eligibility date, change the standard used by the parole
    board to determine parole suitability, or increase the punishment
    imposed for the petitioner’s offense, and the parole eligibility amend-
    ment restored the parole eligibility calculation to 85 percent of the
    petitioner’s definite sentence, thereby returning the petitioner to the
    position he was in at the time of his offense.
    3. This court found unavailing the petitioner’s claim that the parole board’s
    established policy of not awarding parole to any inmate whose parole
    eligibility date was within six months of the date he would have com-
    pleted serving his definite sentence violated the doctrine of separation
    of powers in that such a policy converted a legislatively determined
    parole eligible offense into an offense that, by virtue of executive action,
    was rendered parole ineligible: the petitioner failed to allege that the
    determination of parole eligibility was a power solely vested in the
    legislature and may not be delegated to the executive branch, and the
    circumstances giving rise to such a constitutional defect were extraordi-
    narily speculative because, even if the petitioner earned the maximum
    possible risk reduction credit, the respondent was vested with discretion
    to revoke such credit, and, thus, the claim therefore was premature;
    moreover, the petitioner did not address or challenge a 2015 amendment
    to § 18-98e (a) that rendered him ineligible to earn any further risk
    reduction credit.
    4. The petitioner could not be granted habeas relief on his claim that the
    2013 amendment to the parole eligibility provision of § 54-125a as applied
    to him violated the equal protection clause of the federal constitution
    because there was disparate treatment of classes of inmates by the
    parole board when that board calculated the parole eligibility dates for
    certain inmates who had been granted parole as of July 1, 2013, by
    including earned risk reduction credit, but did not include such credit
    in the calculation of the parole eligibility date for the petitioner and
    other inmates who had not yet been granted parole; even if the two
    classes of inmates were similarly situated, the timing of parole eligibility
    was not a fundamental right and inmates, or subsets of inmates differenti-
    ated only by the timing of when they were considered for parole, are
    not a suspect class, and, accordingly, the application of earned risk
    reduction credit to parole eligibility based on whether an inmate had
    already been granted parole prior to July 1, 2013, did not violate equal
    protection when there was a rational basis for such differentiation, that
    basis being the parole board’s determination that its decision not to
    revoke a grant of parole that had already been awarded supported clarity
    in the administration of parole and an understanding that revocation of
    parole due to no action on the part of the offender could have a negative
    impact on the offender’s rehabilitation and reintroduction into society.
    5. The petitioner could not obtain habeas relief on his claim that § 18-98e
    facially violates the equal protection clause of the federal constitution
    on the ground that it does not permit offenders to earn risk reduction
    credit while held in presentence confinement and, as a result, offenders
    like the petitioner, who cannot afford bail, do not earn risk reduction
    credit for the entire period of their confinement, whereas offenders who
    can afford bail are able to benefit from the award of risk reduction
    credit during their entire sentence; even if these two classes of offenders
    are similarly situated, an inmate has no fundamental right in the opportu-
    nity to earn risk reduction credit because such credit is a statutory
    creation and is not constitutionally required, the petitioner has not
    alleged that, as a result of § 18-98e, he, or other indigent individuals, have
    been imprisoned beyond the maximum period authorized by statute, the
    class’ status as indigent individuals did not constitute a suspect class, and
    there are numerous rational bases for treating presentence confinement
    differently under a credit statute, including the different purposes of
    presentence confinement and incarceration after sentencing.
    6. The petitioner could not be granted habeas relief on his statutory claim
    that a proper interpretation of the 2013 amendments to the parole eligibil-
    ity and hearing provisions of § 54-125a would limit application of those
    provisions prospectively to inmates who were committed to the respon-
    dent’s custody to begin serving their sentences on or after July 1, 2013,
    that claim having been premature; it was uncertain whether the parole
    board would decline to conduct a parole hearing when the petitioner
    became eligible for parole, and if the parole board decided to hold a
    hearing or if the petitioner did not have any earned risk reduction credit
    remaining that would have advanced his parole eligibility date under
    the 2011 parole eligibility provision, then retroactive application to the
    petitioner of the 2013 amendments would not cause the petitioner to
    suffer an actual injury.

    Procedural History
    Amended petition for a writ of habeas corpus,
    brought to the Superior Court in the judicial district of
    Tolland, where the court, Fuger, J., granted the respon-
    dent’s motion to dismiss and rendered judgment dis-
    missing the petition, from which the petitioner, on the
    granting of certification, appealed. Affirmed.

    lant (petitioner).

    Opinion
    McDONALD, J. This case presents challenges to the
    constitutionality of substantive and procedural amend-
    ments to General Statutes (Rev. to 2013) § 54-125a,
    which governs parole eligibility for persons who
    received a definite sentence or aggregate sentence of
    more than two years, as applied to an offender who was
    sentenced before the amendments took effect. More
    specifically, we consider statutory amendments (1)
    eliminating earned risk reduction credit from the calcu-
    lation of a violent offender’s parole eligibility date, when
    such credit was not available at the time the offense
    was committed; Public Acts 2013, No. 13-3, § 59 (P.A.
    13-3); and (2) altering parole eligibility hearing proce-
    dures to allow the Board of Pardons and Paroles to
    forgo holding a hearing. Public Acts 2013, No. 13-247,
    § 376 (P.A. 13-247). The petitioner, Dominic Perez,
    appeals1 from the judgment of the habeas court dismiss-
    ing his petition claiming that application of these 2013
    amendments to him violated his state and federal due
    process and liberty rights, the ex post facto clause of
    the United States constitution, the separation of powers
    doctrine, and the equal protection clause of the United
    States constitution, and is contrary to the language of
    § 54-125a. The petitioner contends that the habeas court
    improperly dismissed his claims on the ground that it
    would be speculative whether the statutory changes
    would cause any injury to the petitioner because the
    award of risk reduction credit by the respondent, the
    Commissioner of Correction, is discretionary. We agree
    with the petitioner to the extent that the habeas court
    improperly dismissed many of the claims raised in the
    petition solely on the basis of the ‘‘speculative nature’’
    of earned risk reduction credit. Nevertheless, applying
    the proper test to each claim raised by the petitioner,
    we hold that the habeas court lacked jurisdiction over
    the petitioner’s claims. We therefore affirm the judg-
    ment of the habeas court dismissing the petition.
    I
    The following procedural and statutory history is rele-
    vant to this appeal. The petitioner committed the
    offenses giving rise to his incarceration, which involved
    his use of deadly force, in November, 2010. At that time,
    the relevant parole eligibility provision of § 54-125a pro-
    vided in relevant part: ‘‘A person convicted of . . . an
    offense, other than [certain parole ineligible offenses]
    where the underlying facts and circumstances of the
    offense involve the use, attempted use or threatened
    use of physical force against another person shall be
    ineligible for parole under subsection (a) of this section
    until such person has served not less than eighty-five
    per cent of the definite sentence imposed.’’ General
    Statutes (Rev. to 2009) § 54-125a (b) (2), as amended
    by Public Acts 2010, No. 10-36, § 30. At that time, the
    relevant parole hearing provision of § 54-125a provided
    that the board ‘‘shall hold a hearing to determine the
    suitability for parole release of any person whose eligi-
    bility for parole release is subject to the provisions of
    subdivision (2) of subsection (b) of this section upon
    completion by such person of eighty-five percent of
    such person’s definite or aggregate sentence. . . .’’
    (Emphasis added.) General Statutes (Rev. to 2009) § 54-
    125a (e).
    In July, 2011, while the petitioner’s criminal case was
    pending before the trial court, General Statutes § 18-
    98e2 became effective, pursuant to which the respon-
    dent had discretion to award risk reduction credit
    toward a reduction of an inmate’s sentence, up to five
    days per month, for positive conduct. General Statutes
    § 18-98e (a) and (b). The respondent also was vested
    with discretion to revoke such credit, even credit yet
    to be earned, for good cause. See General Statutes § 18-
    98e (b). At the same time, the legislature amended the
    parole eligibility provision to provide: ‘‘A person con-
    victed of . . . an offense . . . where the underlying
    facts and circumstances of the offense involve the use,
    attempted use or threatened use of physical force
    against another person shall be ineligible for parole
    under subsection (a) of this section until such person
    has served not less than eighty-five per cent of the
    definite sentence imposed less any risk reduction
    credit earned under the provisions of section 18-98e.’’
    (Emphasis added.) General Statutes (Rev. to 2011) § 54-
    125a (b) (2), as amended by Public Acts 2011, No. 11-
    51, § 25 (P.A. 11-51). The subsection of § 54-125a
    addressing parole hearings was similarly amended to
    account for earned risk reduction credit. General Stat-
    utes (Rev. to 2011) § 54-125 (e), as amended by P.A.
    11-51, § 25. Accordingly, under the 2011 amendments,
    earned risk reduction credit was to be applied to an
    inmate’s definite sentence to advance the inmate’s end
    of sentence date, and the parole eligibility date calcu-
    lated as a percentage of the sentence would advance
    in similar measure.
    In May, 2013, the petitioner was sentenced to a total
    effective sentence of fifteen years incarceration after
    he pleaded guilty to manslaughter in the first degree
    with a firearm in violation of General Statutes § 53a-
    55a, and carrying a pistol without a permit in violation
    of General Statutes (Rev. to 2009) § 29-35 (a), for the
    2010 offense. Under the 2011 amendments to § 54-125a
    and § 18-98e, any risk reduction credit earned by an
    inmate, and not subsequently revoked, would have both
    reduced his sentence and rendered him eligible for a
    hearing to determine whether he should be granted
    parole after he had served 85 percent of that reduced
    sentence.
    Effective July 1, 2013, the legislature again amended
    § 54-125a. Specifically, with regard to offenses like one
    of those of which the petitioner was convicted, the
    legislature eliminated the language that permitted the
    parole eligibility date to be advanced by the application
    of any earned risk reduction credit. See P.A. 13-3. The
    legislature also eliminated the requirement that the
    board ‘‘shall’’ hold a parole hearing after such inmates
    had completed 85 percent of their definite or aggregate
    sentences. See P.A. 13-247. Instead, under the revised
    statute, the board ‘‘may’’ hold such a hearing, but ‘‘[i]f
    a hearing is not held, the board shall document the
    specific reasons for not holding a hearing and provide
    such reasons to such person. . . .’’ General Statutes
    (Supp. 2014) § 54-125a (e). Thus, under the 2013 amend-
    ments, any risk reduction credit earned by an inmate,
    and not subsequently revoked, would still be applied
    to reduce his sentence, but would not be applied to
    advance his parole eligibility date. In other words, he
    would only be eligible for a hearing to determine
    whether he should be granted parole after he had served
    85 percent of his original sentence (in the petitioner’s
    case, after twelve years and nine months). Moreover,
    the board may decline to hold a hearing once that eligi-
    bility date arises.
    The petitioner thereafter filed his petition for a writ
    of habeas corpus challenging the application of the 2013
    amendments to the calculation of his parole eligibility
    date and to his right to a hearing on his suitability
    for parole. In the operative thirteen count petition, the
    petitioner alleged that he already had been awarded
    risk reduction credit by the respondent and that prior
    to July 1, 2013, the respondent had applied that credit
    to advance the petitioner’s parole eligibility date. The
    petitioner challenged the application of these amend-
    ments to him by the respondent3 as a violation of his
    constitutional rights under the federal and/or state con-
    stitution—specifically, claims related to due process,
    liberty interests, the ex post facto clause, the separation
    of powers doctrine and the equal protection clause—
    and as contrary to the statutory text. Subsequently,
    the respondent filed a motion to dismiss all counts of
    the petition.
    After a hearing, the habeas court granted the respon-
    dent’s motion to dismiss the petition. The habeas court’s
    decision did not analyze each claim separately. Rather,
    it concluded that all of the petitioner’s claims failed on
    the same basis, namely, that ‘‘[g]iven the speculative
    nature of [earned risk reduction credit], and the
    [respondent’s] discretion to both award and take [it]
    away as an administrative tool to manage the inmate
    population, [the habeas] court . . . lacks subject mat-
    ter jurisdiction over the . . . petition and . . . [the
    petition] fails to state a claim upon which habeas corpus
    relief can be granted.’’ This appeal followed.
    II
    The petitioner asserts that the habeas court improp-
    erly dismissed all of his claims based on lack of justicia-
    bility, a conclusion that he contends the habeas court
    would not have reached had it properly analyzed each
    claim separately under the appropriate respective juris-
    dictional test. The petitioner argues that the habeas
    court improperly interpreted his claims as dependent
    on the future award of risk reduction credit to the
    petitioner, and, therefore, too speculative a basis for
    habeas relief. He contends that the claims challenging
    the hearing provision are not dependent on whether
    earned risk reduction credit is applied to determine his
    parole eligibility date. He further asserts that the claims
    challenging the parole eligibility provision are not
    dependent on any future award of risk reduction credit
    because he already had been awarded credit, which the
    respondent used to calculate his new parole eligibility
    date prior to July 1, 2013.
    The respondent asserts that the habeas court prop-
    erly dismissed all of the petitioner’s claims, even though
    it did not address each claim separately in its analysis,
    because the claims were so clearly without a legal or
    factual basis that no analysis was required. The respon-
    dent further asserts that even if the reason stated by
    the habeas court for dismissing the entire petition was
    improper, the court nevertheless lacked jurisdiction
    over each claim, and this court may affirm the habeas
    court’s granting of the respondent’s motion to dismiss
    on alternative grounds.4 We conclude that, under a
    proper analysis of the individual claims, the habeas
    court properly dismissed the petition in its entirety.
    Practice Book § 23-29 provides: ‘‘The judicial author-
    ity may, at any time, upon its own motion or upon
    motion of the respondent, dismiss the petition, or any
    count thereof, if it determines that: (1) the court lacks
    jurisdiction; (2) the petition, or a count thereof, fails
    to state a claim upon which habeas corpus relief can
    be granted; (3) the petition presents the same ground
    as a prior petition previously denied and fails to state
    new facts or to proffer new evidence not reasonably
    available at the time of the prior petition; (4) the claims
    asserted in the petition are moot or premature; (5) any
    other legally sufficient ground for dismissal of the peti-
    tion exists.’’
    ‘‘[I]n order to invoke successfully the jurisdiction of
    the habeas court, a petitioner must allege an interest
    sufficient to give rise to habeas relief.’’ (Internal quota-
    tion marks omitted.) Baker v. Commissioner of Correc-
    tion, 
    281 Conn. 241
    , 251, 
    914 A.2d 1034
    (2007). ‘‘We
    have long held that because [a] determination regarding
    a trial court’s subject matter jurisdiction is a question
    of law, our review is plenary.’’ (Internal quotation marks
    omitted.) Ajadi v. Commissioner of Correction, 
    280 Conn. 514
    , 532, 
    911 A.2d 712
    (2006). Likewise,
    ‘‘[w]hether a habeas court properly dismissed a petition
    pursuant to Practice Book § 23-29 (2), on the ground
    that it ‘fails to state a claim upon which habeas corpus
    relief can be granted,’ presents a question of law over
    which our review is plenary.’’ Kaddah v. Commissioner
    of Correction, 
    324 Conn. 548
    , 559, 
    153 A.3d 1233
    (2017).
    As reflected in the analysis that follows, we conclude
    that the habeas court improperly based its dismissal of
    all of the petitioner’s claims, challenging the effect of
    the 2013 amendments, solely on the basis of the ‘‘specu-
    lative nature’’ of the future award of risk reduction
    credit. Insofar as the habeas court intended ‘‘specula-
    tive nature’’ to encompass both the discretionary nature
    of the risk reduction credit scheme and the prematurity
    of any claim based on the future award of such credit,
    we agree that those aspects of earned risk reduction
    credit are relevant to some of the petitioner’s claims
    challenging the parole eligibility provision. The peti-
    tioner has raised a variety of claims challenging the
    parole eligibility and hearing provisions, however, not
    all of which implicate the discretionary or prospective
    nature of earned risk reduction credit. See Baker v.
    Commissioner of 
    Correction, supra
    , 
    281 Conn. 260
    –61
    (comparing jurisdictional requirements for ex post
    facto claim with due process claim). Nonetheless, if
    the habeas court reached the correct decision, but on
    mistaken grounds, this court will sustain the habeas
    court’s action if proper grounds exist to support it.
    Perez-Dickson v. Bridgeport, 
    304 Conn. 483
    , 540, 
    43 A.3d 69
    (2012) (Palmer, J., concurring). Therefore, we
    conduct a plenary review to determine if the habeas
    court lacked jurisdiction over each claim raised in the
    petition, and we analyze the petitioner’s claims together
    only insofar as they turn on the same legal framework.
    A
    The petitioner points to the fact that, prior to the
    effective date of the 2013 amendments, he had already
    earned risk reduction credit. In reliance solely on that
    ‘‘earned’’ credit, the petitioner claims that the 2013
    amendment eliminating the application of that credit
    to advance his parole eligibility date5 violates his right
    to due process under the federal and state constitutions
    and his right to personal liberty pursuant to article first,
    § 9, of the Connecticut constitution.6 See P.A. 13-3. The
    petitioner similarly claims that the 2013 amendment
    eliminating the parole hearing mandate violates his right
    to due process under the federal and state constitutions
    and his right to personal liberty pursuant to article first,
    § 9, of the Connecticut constitution. See P.A. 13-247.
    We disagree with these claims.
    An essential predicate to all of these claims is a cogni-
    zable liberty interest. When a petitioner seeks habeas
    relief on the basis of a purported liberty interest in
    parole eligibility, he is invoking ‘‘a liberty interest pro-
    tected by the [d]ue [p]rocess [c]lause of the [f]ourteenth
    amendment which may not be terminated absent appro-
    priate due process safeguards.’’ (Footnote omitted.)

    Correction, supra
    , 
    281 Conn. 252
    . ‘‘In order . . . to qualify as a constitutionally pro-
    tected liberty, [however] the interest must be one that
    is assured either by statute, judicial decree, or regula-
    tion.’’ (Emphasis in original; internal quotation marks
    omitted.)

    a right has vested is

    This court previously has held that ‘‘parole eligibility
    under § 54-125a does not constitute a cognizable liberty
    interest sufficient to invoke habeas jurisdiction.’’ 
    Id., 261–62. In
    reaching this conclusion, we noted that ‘‘the
    decision to grant parole is entirely within the discretion
    of the board. Indeed, this court squarely has held that,
    ‘[t]here is no statutory requirement that the panel [of
    the board] actually consider the eligibility of any inmate
    for parole, the statute does not vest an inmate with
    the right to demand parole, and there is no statutory
    provision which even permits an inmate to apply for
    parole. . . . For even if the inmate has complied with
    the minimum requirements of [the parole statute], the
    statute does not require the board to determine his
    eligibility for parole.’ . . . Taylor v. Robinson, [
    171 Conn. 691
    , 697–98, 
    372 A.2d 102
    (1976)].’’7 Baker v.
    Commissioner of 
    Correction, supra
    , 
    281 Conn. 257
    . We
    further noted that ‘‘the parole eligibility statute is not
    within the terms of the sentence imposed.’’ (Internal
    quotation marks omitted.) 
    Id., 260. In
    the present case, neither the substantive (parole
    eligibility calculation) nor the procedural (hearing)
    changes under the 2013 amendments altered the funda-
    mental fact that the determination whether to grant an
    inmate parole is entirely at the discretion of the board.
    It follows that if an inmate has no vested liberty interest
    in the granting of parole, then the timing of when the
    board could, in its discretion, grant parole does not rise
    to the level of a vested liberty interest either. The lack
    of a vested interest giving rise to a due process claim
    is further compounded by the fact that under the provi-
    sions effective in 2011; P.A. 11-51; the award of risk
    reduction credit itself is at the discretion of the
    respondent.
    With respect to the risk reduction credit previously
    granted to the petitioner, he overlooks the fact that
    such credit is not vested in him because it could be
    rescinded by the respondent at any time in the respon-
    dent’s discretion for good cause during the petitioner’s
    period of incarceration. The petitioner, in his brief, dis-
    putes that the award or revocation of risk reduction
    credit is wholly discretionary, but does not provide any
    analysis to support this assertion, instead claiming that
    the scope of the respondent’s discretion is not neces-
    sary to resolve this motion to dismiss and would be
    addressed in a trial on the merits. The petitioner’s posi-
    tion, however, is manifestly contradicted by the plain
    language of § 18-98e (a), which provides that an inmate
    may be eligible to earn risk reduction credit ‘‘at the
    discretion of the [respondent] for conduct as provided
    in subsection (b) of this section,’’ and § 18-98e (b) (2),
    which provides that ‘‘the [respondent] . . . may, in his
    or her discretion, cause the loss of all or a portion of
    such earned risk reduction credit for any act of miscon-
    duct or insubordination or refusal to conform to recom-
    mended programs or activities or institutional rules
    occurring at any time during the service of the sentence
    or for other good cause.’’ Although the legislature has
    provided guidance to the respondent as to how to exer-
    cise his discretion, the respondent still has broad discre-
    tion to award or revoke risk reduction credit. As such,
    the statute does not support an expectation that an
    inmate will automatically earn risk reduction credit or
    will necessarily retain such credit once it has been
    awarded.
    The petitioner further relies on the monthly calcula-
    tion of his parole eligibility date that he purportedly
    receives from the respondent, which included his
    earned risk reduction credit prior to July 1, 2013, as
    evidence that he has a vested interest in continuing to
    have that earned risk reduction credit reflected in his
    parole eligibility date. See General Statutes § 18-98e (a)
    (inmate is ‘‘eligible to earn risk reduction credit toward
    a reduction of such person’s sentence, in an amount
    not to exceed five days per month’’). The petitioner
    misapprehends the significance of the respondent’s
    monthly parole eligibility date calculation. Under the
    scheme even prior to 2013, because the respondent
    could have rescinded any or all of that earned credit
    in his discretion, the monthly parole eligibility date is
    nothing more than an estimate of the inmate’s parole
    eligibility date. As such, the monthly parole eligibility
    date calculation is simply an informational tool to allow
    the respondent and an inmate to know at any given
    time how close to parole eligibility the inmate would be
    if nothing changed. Accordingly, the petitioner lacked a
    vested right in the application of the risk reduction
    credit previously granted to advance his parole eligibil-
    ity date.
    Similarly, the pre-2013 language providing that the
    board ‘‘shall’’ hold a parole hearing did not alter the
    fact that the determination of whether to grant an
    inmate parole is entirely at the discretion of the board.
    General Statutes (Rev. to 2009) § 54-125a (e). Where,
    as here, an inmate has no vested liberty interest in
    parole itself, then it follows that the procedure by which
    the board exercises its discretion to award or deny the
    petitioner parole does not implicate a vested liberty
    interest. See Baker v. Commissioner of 
    Correction, supra
    , 
    281 Conn. 257
    (‘‘[T]here is no statutory require-
    ment that the [board] actually consider the eligibility
    of any inmate for parole, the statute does not vest an
    inmate with the right to demand parole, and there is
    no statutory provision [that] even permits an inmate to
    apply for parole. . . . For even if the inmate has com-
    plied with the minimum requirements of [the parole
    statute], the statute does not require the board to deter-
    mine his eligibility for parole.’’ [Internal quotation
    marks omitted.]). Therefore, the habeas court lacked
    jurisdiction over the petitioner’s due process and state
    liberty interest claims.
    B
    The petitioner also claims that the retroactive appli-
    cation of the 2013 amendments to him, when he commit-
    ted his offense and was sentenced prior to the
    amendments’ effective date, violates the ex post facto
    clause of the United States constitution. Specifically,
    he points to the fact that the elimination of earned
    risk reduction credit from the calculation of his parole
    eligibility date will require him to serve a longer portion
    of his sentence before he may be considered for parole,
    and, even then, the elimination of a mandatory hearing
    upon his parole eligibility date will result in a significant
    risk that he will be subject to a longer period of incarcer-
    ation than under the mandatory hearing provision.
    We disagree.
    ‘‘A law may be considered to violate the ex post
    facto clause if it punishes as a crime an act previously
    committed, which was innocent when done; which
    makes more burdensome the punishment for a crime,
    after its commission, or which deprives one charged
    with [a] crime of any defense available according to
    law at the time when the act was committed . . . .’’

    321 Conn. 821
    , 844–45, 
    146 A.3d 1
    (2016). The petitioner’s
    claims in the present case implicate the second aspect
    of the ex post facto clause.
    In contrast to a claim grounded in the due process
    clause, ‘‘[t]he presence or absence of an affirmative,
    enforceable right is not relevant . . . to the ex post
    facto prohibition, which forbids the imposition of pun-
    ishment more severe than the punishment assigned by
    law when the act to be punished has occurred. Critical
    to relief under the [e]x [p]ost [f]acto [c]lause is not an
    individual’s right to less punishment, but the lack of fair
    notice and governmental restraint when the legislature
    increases punishment beyond what was prescribed
    when the crime was consummated. Thus, even if a
    statute merely alters penal provisions accorded by the
    grace of the legislature, it violates the [c]lause if it is
    both retrospective and more onerous than the law in
    effect on the date of the offense.’’ (Internal quotation
    marks omitted.) Johnson v. Commissioner of Correc-
    tion,

    omitted]).
    ‘‘[T]he primary focus of an ex post facto claim is
    the probability of increased punishment. To establish
    a cognizable claim under the ex post facto clause, there-

    .
    We begin with the petitioner’s challenge to the retro-
    active application of the 2013 parole hearing provision,
    P.A. 13-247. As we indicated in part I of this opinion,
    the statute in effect when the petitioner committed his
    offense stated that the board shall conduct a hearing
    when a person has completed 85 percent of his total
    effective sentence. General Statutes (Rev. to 2009) § 54-
    125a (e). The 2013 amendment provides that the board
    may conduct a hearing at that time, but requires that,
    in the event that the board declines to hold a hearing,
    it must document the specific reasons for not doing so
    and provide such reasons to the offender. See P.A. 13-
    247. Therefore, under both the pre-2013 and post-2013
    scheme, the board could not release an offender on
    parole without having conducted a hearing.8
    Our conclusion that the 2013 parole hearing provision
    did not violate the ex post facto clause is guided by the
    United States Supreme Court’s decision in California
    Dept. of Corrections v. Morales, 
    514 U.S. 499
    , 
    115 S. Ct. 1597
    , 
    131 L. Ed. 2d 588
    (1995). In that case, the court
    held that a change in the frequency of parole hearings
    for certain offenders did not constitute an ex post facto
    violation. 
    Id., 510, 514.
    Under the statute in place at the
    time of that offender’s crime, an offender was entitled
    to an initial parole hearing upon his parole eligibility
    date, and, if denied parole, he was thereafter entitled
    to annual hearings. 
    Id., 503. The
    legislature amended
    the statute to provide that, after the initial hearing,
    the parole board could elect to wait three years for a
    subsequent hearing if it determined at the initial hear-
    ing, or at any hearing thereafter, that the offender was
    unlikely to become suitable for parole within three
    years. 
    Id. In reaching
    its conclusion that retroactive
    application of this change was permissible, the court
    explained that ‘‘the focus of the ex post facto inquiry
    is not on whether a legislative change produces some
    ambiguous sort of ‘disadvantage,’ nor . . . on whether
    an amendment affects a prisoner’s ‘opportunity to take
    advantage of provisions for early release’ . . . but on
    whether any such change alters the definition of crimi-
    nal conduct or increases the penalty by which a crime
    is punishable.’’ (Citation omitted; emphasis omitted.)
    
    Id., 506–507 n.3;
    see also Garner v. Jones, 
    529 U.S. 244
    ,
    251–52, 
    120 S. Ct. 1362
    , 
    146 L. Ed. 2d 236
    (2000) (noting
    that ex post facto clause must not be used as tool to
    micromanage legislative adjustments to parole proce-
    dures and is only violated when retroactive application
    of procedural changes creates significant risk of
    increased punishment). The court further explained
    that ‘‘[i]f a delay in parole hearings raises ex post facto
    concerns, it is because that delay effectively increases
    a prisoner’s term of confinement, and not because the
    hearing itself has independent constitutional signifi-
    cance.’’ California Dept. of Corrections v. 
    Morales, supra
    , 509 n.4. The court noted that the amended provi-
    sion at issue did not alter the offender’s parole eligibility
    date or otherwise increase his sentence. 
    Id., 507. The
    court also noted that the board was required to hold
    the initial hearing and make findings before delaying
    the next hearing for three years. 
    Id., 511. In
    the present case, as in Morales, the challenged
    parole hearing provision does not increase the petition-
    er’s overall sentence, alter his initial parole eligibility
    date, or change the standard used by the board to deter-
    mine parole suitability. Although the board is no longer
    required to provide an initial hearing, it must document
    its reasons if it declines to do so. Because the parole
    hearing provision does not alter the calculation of when
    an inmate is eligible for parole, and because the board
    must still consider the inmate’s parole suitability at that
    time, the elimination of a mandatory hearing in the
    2013 parole hearing provision does not increase the
    punishment imposed for the petitioner’s offense. There-
    fore, the habeas court lacked jurisdiction to consider
    the petitioner’s ex post facto claim concerning the
    parole hearing provision.
    We next turn to the petitioner’s challenge to the 2013
    amendment to the parole eligibility provision, P.A. 13-
    3. As noted in part I of this opinion, when the petitioner
    committed his offense in 2010, a violent offender for
    whom parole was available would become eligible for
    parole after he had served 85 percent of his definite
    sentence. See General Statutes (Rev. to 2009) § 54-125a
    (e). Although a short-lived 2011 amendment altered this
    calculation to include earned risk reduction credit; P.A.
    11-51, § 25; the challenged 2013 amendment restored
    the parole eligibility calculation to 85 percent of the
    violent offender’s definite sentence. Far from creating
    a genuine risk that the petitioner would be incarcerated
    for a longer period of time, the 2013 parole eligibility
    provision simply returned the petitioner to the position
    that he was in at the time of his offense.9
    The petitioner contends, however, that, in conducting
    the ex post facto inquiry, this court is not limited to
    comparing the challenged statute with the statute in
    effect at the time the offense was committed. Rather,
    the petitioner contends that Lynce v. Mathis, 
    519 U.S. 433
    , 
    117 S. Ct. 891
    , 
    137 L. Ed. 2d 63
    (1997), supports the
    proposition that a court also may consider the statute in
    effect at the time of his plea and sentencing. We disagree
    that Lynce supports this proposition.
    In Lynce, the Supreme Court held that the habeas
    court had jurisdiction to consider a petitioner’s claim
    that a Florida statute eliminating good time credit,
    which resulted in the revocation of the petitioner’s
    parole based on such credit and his rearrest, violated
    the ex post facto clause. 
    Id., 438–39, 449.
    At the time
    of the commission of the offense at issue in Lynce,
    mandatory good time credit was issued to eligible
    inmates when the inmate population exceeded a spe-
    cific percentage of prison capacity. 
    Id., 437–39. Prior
    to the petitioner’s sentencing, an amendment took
    effect that decreased the percentage of prisoner capac-
    ity that triggered the mandatory issuance of credit. 
    Id., 438. The
    petitioner was released on parole on the basis
    of the various credits issued to him. 
    Id. Thereafter, the
    legislature amended the statute to eliminate altogether
    credit based on prison population for certain classes
    of inmates. 
    Id., 438–39. The
    petitioner’s credits were
    revoked and he was rearrested. 
    Id., 439. Notably,
    in
    concluding that the habeas court had jurisdiction over
    the petitioner’s ex post facto claim, the court relied on
    the fact that the provision enacted after the petitioner
    committed his criminal offense, and that resulted in his
    initial release on parole, was ‘‘essentially the same’’ as
    the provision in effect at the time of his offense, differing
    only in the percentage of prison capacity that triggered
    the award, and, therefore, the fact that the petitioner
    was awarded credit based on the statute in effect at
    the time of his sentencing, rather than the statute in
    effect at the time of his offense, ‘‘[did] not affect the
    petitioner’s core ex post facto claim.’’ 
    Id., 448–49. The
    court emphasized, however, ‘‘that although the differ-
    ences in the statutes did not affect [the] petitioner’s
    central entitlement to [credit], they may have affected
    the precise amount of [credit] he received.’’ 
    Id., 449. Because
    it was unclear from the record whether, and
    to what extent, the petitioner would have been issued
    credit under the statute in effect at the time of the
    commission of his crime—the focal point of the ex post
    facto inquiry—the court remanded the case for further
    proceedings to determine the merits of the ex post facto
    claim. 
    Id. The court
    pointed out that, if the conditions
    had not occurred that would have triggered the issuance
    of credit under that statute, then ‘‘there is force to the
    argument that [revocation of credit earned under the
    statute in effect at the time of sentencing] did not violate
    the [e]x [p]ost [f]acto [c]lause.’’ 
    Id. The mandatory
    nature of the good time credit scheme made it possible
    for the habeas court to determine on remand whether
    the petitioner would have received credit had the
    scheme not been changed from the time of his offense.
    Thus, the court looked past the statute in effect at
    the time the petitioner was sentenced and pursuant to
    which he had been awarded credit, and instead com-
    pared the statute in effect at the time of the criminal
    offense to the challenged statute repealing the credit.
    Accordingly, Lynce supports the traditional
    approach, comparing the statute in effect at the time
    of the petitioner’s offense to the challenged statute, not
    the one advocated by the petitioner in the present case.
    Under that approach, the petitioner does not state a
    cognizable ex post facto claim.
    C
    The petitioner also claims that the board’s application
    of the 2013 parole eligibility provision violates the doc-
    trine of separation of powers by converting a legisla-
    tively determined parole eligible offense into an offense
    that, by virtue of executive action, is rendered parole
    ineligible. Specifically, the petition alleges that the
    board has an established policy of not awarding parole
    to any inmate whose parole eligibility date is within
    six months of the date on which the inmate will have
    completed serving his definite sentence. He further
    alleges that if he continues to earn ‘‘all possible’’ risk
    reduction credit—five days per month, every month—
    his sentence will be reduced to within six months of his
    parole eligibility date under the 2013 parole eligibility
    provision—85 percent of his original sentence. As such,
    he contends that the board will not consider him for
    parole, even though the legislature has deemed his
    offense parole eligible, in violation of the separation of
    powers doctrine.
    Putting aside the significant problem that the peti-
    tioner has failed to allege that the determination of
    parole eligibility is a power solely vested in the legisla-
    ture and may not be delegated to the executive branch,
    an essential element of a viable separation of powers
    claim; see generally Massameno v. Statewide Griev-
    ance Committee, 
    234 Conn. 539
    , 552–53, 
    663 A.2d 317
    (1995); he ignores the fact that the circumstance that
    he claims purportedly would give rise to such a constitu-
    tional defect is extraordinarily speculative. He not only
    would have to earn the maximum possible credit, but
    would also have to have had none of the credit revoked,
    both acts wholly left to the respondent’s discretion.
    Even if such a circumstance could arise, any claim
    based on such facts would be premature. Further, the
    petitioner has ignored the fact that a 2015 amendment to
    § 18-98e (a), which he has not challenged in his petition,
    rendered him ineligible to earn any risk reduction credit
    as of October 1, 2015. See Public Acts 2015, No. 15-216,
    § 9. Accordingly, for a host of reasons, the habeas court
    properly concluded that it lacked subject matter juris-
    diction over this claim. See Janulawicz v. Commis-
    sioner of Correction, 
    310 Conn. 265
    , 270–71, 
    77 A.3d 113
    (2013).
    D
    The petitioner raises two equal protection chal-
    lenges—an as applied challenge to the parole eligibility
    provision of § 54-125a and a facial challenge to § 18-
    98e.10 First, he contends that the 2013 parole eligibility
    provision as applied to him violates the equal protection
    clause of the United States constitution because violent
    offenders who were granted parole between the effec-
    tive dates of the 2011 and 2013 amendments (from July
    1, 2011 through June 30, 2013), but who had not yet
    been physically released on parole until July 1, 2013
    or later, benefited from the inclusion of earned risk
    reduction credit in the calculation of their parole eligi-
    bility dates, whereas, violent offenders who were not
    yet granted parole as of July 1, 2013, including the
    petitioner, will not benefit from the inclusion of such
    credit in the calculation of their parole eligibility dates.
    Put differently, he contends that there is disparate treat-
    ment because the board does not eliminate the inclusion
    of earned risk reduction credit from the parole eligibility
    calculation for the first class and in turn revoke their
    grant of parole calculated on the basis of that credit.
    Second, he contends that § 18-98e facially violates equal
    protection because it does not permit offenders to earn
    risk reduction credit while held in presentence confine-
    ment, as was the petitioner. As a result, offenders like
    the petitioner who cannot afford bail do not earn risk
    reduction credit for the entire period of their confine-
    ment, whereas offenders who can afford bail are able
    to benefit from the award of risk reduction credit during
    their entire sentence. We are not persuaded that the
    petitioner has stated a claim on which habeas relief
    may be granted.
    ‘‘[T]o implicate the equal protection [clause] . . . it
    is necessary that the state statute . . . in question,
    either on its face or in practice, treat persons standing
    in the same relation to it differently. . . . [Conse-
    quently], the analytical predicate [of consideration of
    an equal protection claim] is a determination of who
    are the persons similarly situated.’’ (Internal quotation
    marks omitted.) Hammond v. Commissioner of Correc-
    tion, 
    259 Conn. 855
    , 877 n.22, 
    792 A.2d 774
    (2002). Hav-
    ing determined the persons who are similarly situated,
    the court must then establish ‘‘the standard by which
    the challenged statute’s constitutional validity will be
    determined. If, in distinguishing between classes, the
    statute either intrudes on the exercise of a fundamental
    right or burdens a suspect class of persons, the court
    will apply a strict scrutiny standard [under which] the
    state must demonstrate that the challenged statute is
    necessary to the achievement of a compelling state
    interest. . . . If the statute does not touch upon either
    a fundamental right or a suspect class, its classification
    need only be rationally related to some legitimate gov-
    ernment purpose in order to withstand an equal protec-
    tion challenge.’’ (Internal quotation marks omitted.)

    271 Conn. 808
    ,
    831, 
    860 A.2d 715
    (2004).
    This court concluded in Harris that application of
    presentence confinement credit to all sentences
    imposed on a single day in a single location, but not to
    all sentences imposed on separate dates or locations,
    does not violate equal protection. 
    Id., 836. The
    court
    determined that presentence confinement credit, as a
    matter of legislative grace, is not a fundamental right,
    persons who receive concurrent sentences on different
    dates are not a suspect class, and there was a rational
    basis to treat such individuals differently from persons
    sentenced to concurrent sentences on a single date.

    –89 (presentence con-
    finement credit is not fundamental right and persons
    detained in another state while contesting extradition
    are not suspect class). The court relied on settled law
    holding that prisoners do not constitute a suspect class.

    , 1300 (D.C. Cir. 1998). Notably, the court rejected
    a claim that the respondent’s method of applying pre-
    sentence confinement credit violated equal protection
    on the basis of the petitioner’s indigency. Harris v.
    Commissioner of 
    Correction, supra
    , 836–41. The court
    held that indigent persons who cannot afford bail were
    not a suspect class under the scheme because applica-
    tion of the statute did not enable the state to imprison
    a defendant beyond the maximum period authorized
    by statute because of his indigency. 
    Id., 838–40 (poverty
    itself is not suspect class; classification based on pov-
    erty can become suspect class only if statutory scheme
    enables state to imprison defendant beyond maximum
    period authorized by statute because of indigency).
    Turning to the petitioner’s challenge to the parole
    eligibility provision in the present case, even if we
    assume that the two classes are similarly situated, the
    petitioner’s claim would fail. See State v. Wright, 
    246 Conn. 132
    , 143, 
    716 A.2d 870
    (1998) (court has frequently
    assumed, for equal protection purposes, that categories
    of defendants are similarly situated with respect to chal-
    lenged statute). Like the presentence confinement
    credit at issue in Harris, the award and application of
    risk reduction credit is not constitutionally required
    and is a matter of legislative grace. Further, the timing
    of parole eligibility itself is not a fundamental right. See
    Baker v. Commissioner of 
    Correction, supra
    , 
    281 Conn. 253
    (‘‘[t]here is no constitutional or inherent right of a
    convicted person to be conditionally released before
    the expiration of a valid sentence’’ [internal quotation
    marks omitted]); see also McGinnis v. Royster, 
    410 U.S. 263
    , 270, 
    93 S. Ct. 1055
    , 
    35 L. Ed. 2d 282
    (1973)
    (‘‘determination of an optimal time for parole eligibility
    elicit[s] multiple legislative classifications and group-
    ings, which . . . require only some rational basis to
    sustain them’’). Therefore, it follows that application
    of earned risk reduction credit to advance an inmate’s
    parole eligibility date does not impinge on a fundamen-
    tal right. As inmates are not a suspect class; Harris v.
    Commissioner of 
    Correction, supra
    , 
    271 Conn. 833
    ; it
    follows that subsets of inmates differentiated only by
    the timing of when they were considered for parole are
    also not a suspect class. The petitioner has not alleged
    any other basis for considering as a suspect class those
    inmates who were awarded risk reduction credit prior
    to July 1, 2013, but had not yet been granted parole. In
    the absence of a fundamental right or suspect class,
    the application of earned risk reduction credit to parole
    eligibility based on whether an inmate had already been
    granted parole prior to July 1, 2013, does not violate
    equal protection if there is a rational basis for such
    differentiation. The determination by the board that it
    would not revoke a grant of parole that had already
    been awarded supports clarity in the administration of
    parole and also an understanding that revocation of
    parole due to no action on the part of the offender
    could have a negative impact on the offender’s rehabili-
    tation and reintroduction into society. Therefore, the
    petitioner has failed to state a claim for which habeas
    relief may be granted with regard to the parole eligibil-
    ity provision.
    With respect to the petitioner’s claim of disparate
    treatment under § 18-98e, even if we assume that indi-
    gent individuals who cannot afford bail and are held
    in presentence confinement prior to sentencing and
    nonindigent individuals who are not held in presentence
    confinement prior to sentencing are similarly situated,
    the petitioner’s claim is without merit. As previously
    noted, an inmate has no fundamental right in the oppor-
    tunity to earn risk reduction credit because such credit
    is a creature of statute and not constitutionally required.
    The petitioner has not alleged that the earned risk
    reduction credit statute has caused him, or other indi-
    gent individuals, to be imprisoned beyond the maximum
    period authorized by statute. Therefore, the class’ status
    as indigent individuals does not constitute a suspect
    class. In the absence of a fundamental right or a suspect
    class, the exclusion of indigent individuals held in pre-
    sentence confinement from the earned risk reduction
    credit scheme does not violate equal protection if there
    is a rational basis for such treatment. In McGinnis v.
    
    Royster, supra
    , 
    410 U.S. 264
    –65, 277, the United States
    Supreme Court rejected an equal protection challenge
    to a substantially similar New York good time credit
    statute that did not permit the award of credit during
    presentence confinement. The court identified numer-
    ous rational bases for treating presentence confinement
    differently under the credit statute, including the vastly
    different purposes of presentence confinement and
    incarceration after sentencing. 
    Id., 270–73. In
    the con-
    text of the rational bases identified in McGinnis, there-
    fore, the petitioner also has failed to state a claim for
    which habeas relief may be granted with regard to the
    earned risk reduction credit statute.
    E
    The petition summarily alleges that the respondent’s
    construction of the 2013 amendments is contrary to the
    language of § 54-125a and the intent of the legislature
    without pointing to any particular statutory language
    being contravened or identifying the intent of the legis-
    lature in enacting either the 2011 or 2013 amendments.
    On the basis of the petitioner’s brief to this court, we
    understand his claim to be that a proper interpretation
    of the 2013 parole eligibility and parole hearing provi-
    sions would limit application of those provisions pro-
    spectively to inmates who were committed to the
    respondent’s custody to begin serving their sentences
    on or after July 1, 2013, the effective date of those
    provisions.11 In determining whether the habeas court
    had jurisdiction over the petitioner’s claim, however,
    we are limited to the allegations in the petition. See
    Oliphant v. Commissioner of Correction, 
    274 Conn. 563
    , 570, 
    877 A.2d 761
    (2005). Limiting our inquiry to
    the conclusory allegations in the petition, the petitioner
    has failed to allege a statutory application claim upon
    which habeas relief could be granted.
    Further, even if we assume that the petitioner had
    sufficiently alleged the statutory claims he described
    in his brief to this court, and that those claims were
    claims upon which habeas relief could be granted, the
    petitioner’s claims would be premature. ‘‘[A] trial court
    must be satisfied that the case before [it] does not
    present a hypothetical injury or a claim contingent [on]
    some event that has not and indeed may never transpire.
    . . . [R]ipeness is a sine qua non of justiciability . . . .’’
    (Internal quotation marks omitted.) Janulawicz v.
    
    Commissioner, supra
    , 
    310 Conn. 271
    . It is impossible
    to know at this time whether the board will decline to
    conduct a hearing upon the petitioner’s parole eligibility
    date. As discussed more fully in our analysis of the
    petitioner’s due process claims in part II A of this opin-
    ion, even though the petitioner had previously been
    awarded risk reduction credit, it is uncertain whether
    the petitioner will have any earned risk reduction credit
    remaining in the future that would have advanced his
    parole eligibility date under the 2011 parole eligibility
    provision. See General Statutes § 18-98e (b) (authoriz-
    ing respondent to revoke credit, and if earned credit is
    insufficient, to deduct from future earned credit). If the
    board decides to hold a hearing or the petitioner does
    not have any earned risk reduction credit remaining,
    then retroactive application of the 2013 amendments
    would not create an actual injury to the petitioner.
    Therefore, the petitioner’s statutory application claims
    would be premature in any event.
    The judgment is affirmed.
    In this opinion the other justices concurred.
    * This case originally was scheduled to be argued before a panel of this
    court consisting of Chief Justice Rogers and Justices Palmer, Eveleigh,
    McDonald, Espinosa, Robinson and Vertefeuille. Although Justices Palmer
    and Espinosa were not present when the case was argued before the court,
    they have read the briefs and appendices, and listened to a recording of the
    oral argument prior to participating in this decision.
    1
    The habeas court granted the petitioner’s petition for certification to
    appeal pursuant to General Statutes § 52-470 (g). The petitioner subsequently
    appealed from the judgment of the habeas court to the Appellate Court,
    and we transferred the appeal to this court pursuant to General Statutes
    § 51-199 (c) and Practice Book § 65-1.
    2
    General Statutes § 18-98e provides in relevant part: ‘‘(a) Notwithstanding
    any provision of the general statutes, any person sentenced to a term of
    imprisonment for a crime committed on or after October 1, 1994, and commit-
    ted to the custody of the Commissioner of Correction on or after said date
    . . . may be eligible to earn risk reduction credit toward a reduction of
    such person’s sentence, in an amount not to exceed five days per month,
    at the discretion of the Commissioner of Correction for conduct as provided
    in subsection (b) of this section occurring on or after April 1, 2006.
    ‘‘(b) An inmate may earn risk reduction credit for adherence to the inmate’s
    offender accountability plan, for participation in eligible programs and activi-
    ties, and for good conduct and obedience to institutional rules as designated
    by the commissioner, provided (1) good conduct and obedience to institu-
    tional rules alone shall not entitle an inmate to such credit, and (2) the
    commissioner or the commissioner’s designee may, in his or her discretion,
    cause the loss of all or any portion of such earned risk reduction credit for an
    act of misconduct or insubordination or refusal to conform to recommended
    programs or activities or institutional rules occurring at any time during
    the service of the sentence or for other good cause. If an inmate has not
    earned sufficient risk reduction credit at the time the commissioner or the
    commissioner’s designee orders the loss of all or a portion of earned credit,
    such loss shall be deducted from any credit earned by such inmate in the
    future. . . .
    ‘‘(d) Any credit earned under this section may only be earned during the
    period of time that the inmate is sentenced to a term of imprisonment and
    committed to the custody of the commissioner and may not be transferred
    or applied to a subsequent term of imprisonment. . . .’’
    We note that § 18-98e was amended in 2015; see Public Acts 2015, No.
    15-216, § 9; to include additional offenses for which conviction renders an
    inmate ineligible to earn risk reduction credit, including General Statutes
    § 53a-55a, one of the two offenses of which the petitioner is convicted. The
    majority of the petitioner’s claims are based on previously awarded risk
    reduction credit and, therefore, the 2015 amendment is not relevant to those
    claims. Insofar as the petitioner’s separation of powers claim relies on the
    future award of risk reduction credit, however, this amendment is addressed
    in part II C of this opinion.
    3
    The petitioner did not name the Board of Pardons and Paroles as a party
    to his habeas petition. Because we conclude that the habeas court lacked
    jurisdiction over all of the petitioner’s claims, we do not reach the issue of
    whether the board was a necessary or indispensable party. Further, ‘‘[e]ven
    if it is assumed that the board is a necessary or indispensable party, the
    failure to join the board is not a jurisdictional defect depriving the habeas
    court or this court of subject matter jurisdiction.’’ Robinson v. Commis-
    sioner of Correction, 
    258 Conn. 830
    , 837 n.9, 
    786 A.2d 1107
    (2002).
    4
    The respondent also asserts that the petitioner, in his appeal, has aban-
    doned counts seven through thirteen of his petition, in which he raises
    equal protection, separation of powers, and several due process claims, by
    inadequately briefing them. Reading the petitioner’s brief fairly, we have
    determined that he has adequately asserted that the habeas court dismissed
    those claims for an improper reason and explained why the reason was
    improper. We conclude that the petitioner’s brief is minimally sufficient for
    us to address whether the habeas court lacked jurisdiction as to those counts.
    5
    The petitioner is not claiming that he has been deprived of his earned
    risk reduction credit, but merely that the credit he has earned is no longer
    being applied to advance his parole eligibility date. Therefore, we need not
    decide whether a deprivation of his actual earned risk reduction credit
    would violate due process. See Abed v. Armstrong, 
    209 F.3d 63
    , 66–67 (2d
    Cir. 2000) (inmates have liberty interest in good time credit they have already
    earned, but no liberty interest in opportunity to earn credit under discretion-
    ary scheme).
    6
    In his petition, the petitioner alleges that he has a right to personal
    liberty under article first, § 10, of the Connecticut constitution. We construe
    this allegation as a typographical error and note that the right to personal
    liberty is found in article first, § 9, of the Connecticut constitution. The
    petition does not allege, and the petitioner’s briefs to this court do not
    contend, that the petitioner’s right to personal liberty under the state consti-
    tution entitles him to any greater protection than he is due under the due
    process clause of the federal constitution. For purposes of this appeal,
    therefore, we treat those provisions as embodying the same level of protec-
    tion. E.g., Florestal v. Government Employees Ins. Co., 
    236 Conn. 299
    , 314
    n.8, 
    673 A.2d 474
    (1996); see also State v. Lamme, 
    216 Conn. 172
    , 177, 
    579 A.2d 484
    (1990) (article first, § 9, is state constitutional provision guaranteeing due
    process of law).
    7
    ‘‘In Board of Pardons v. Allen, [
    482 U.S. 369
    , 378–79 n.10, 
    107 S. Ct. 2415
    ,
    
    96 L. Ed. 2d 303
    (1987)], the Supreme Court noted that circuit courts had
    held that, ‘statutes or regulations that provide that a parole board ‘‘may’’
    release an inmate on parole do not give rise to a protected liberty interest.’ ’’
    Baker v. Commissioner of 
    Correction, supra
    , 
    281 Conn. 256
    n.13.
    8
    The respondent asserts that the 2013 parole hearing provision merely
    resolved conflicting language in General Statutes (Rev. to 2009) §§ 54-124a
    (h) and 54-125a (e) regarding when a hearing must be held and codified the
    accepted practice of the board. Because we conclude that the parole hearing
    provision does not create a genuine risk that the petitioner will be incarcer-
    ated for a longer period of time than that under the provision in place at
    the time of his offense, we decline to reach the issue of whether the purported
    practice of the board prior to 2013 is an appropriate consideration in
    determining whether the petitioner has raised a valid ex post facto claim
    in the context of a motion to dismiss.
    9
    We understand the petitioner’s argument before this court at oral argu-
    ment to include the assertion that, if he were to earn near the maximum
    amount of risk reduction credit authorized by § 18-98e (a)—five days per
    month, every month—the 2013 parole eligibility provision would not place
    him in the same position that he would have been in pursuant to the parole
    eligibility provision in effect at the time of his offense because, under those
    circumstances, he would be denied any possibility of parole. Although we
    explore and explain this speculative factual scenario in connection with the
    petitioner’s separation of powers claim in part II C of this opinion, we note
    that the petitioner did not raise this argument in the ex post facto section
    of his petition or his brief to this court. Therefore, we decline to reach the
    issue of whether the court would have jurisdiction over his ex post facto
    claim based on such circumstances. See Grimm v. Grimm, 
    276 Conn. 377
    ,
    393, 
    886 A.2d 391
    (2005) (‘‘claims [raised] on appeal must be adequately
    briefed, and cannot be raised for the first time at oral argument before the
    reviewing court’’), cert. denied, 
    547 U.S. 1148
    , 
    126 S. Ct. 2296
    , 
    164 L. Ed. 2d
    815 (2006).
    10
    The petitioner also claims a violation of equal protection under article
    first, § 20, of the Connecticut constitution, but he has failed to provide an
    independent analysis under the state constitution. For purposes of this
    appeal, therefore, we treat both provisions as embodying the same level of
    protection. E.g., Florestal v. Government Employees Ins. Co., 
    236 Conn. 299
    , 314 n.8, 
    673 A.2d 474
    (1996).
    11
    The petitioner does not provide this court with any analysis as to why
    the 2013 amendments must be applied prospectively only. This court has
    undertaken analysis to determine whether a criminal statute is prospective
    or retroactive when the statute is silent as to whether it applies retroactively.
    See State v. Nathaniel S., 
    323 Conn. 290
    , 294–95, 
    146 A.3d 988
    (2016) (in
    absence of clear legislative guidance, substantive statutes apply prospec-
    tively and procedural statutes apply retroactively).
