*78The petitioner, Courtney Green, appeals from the judgment of the habeas court disposing of his petition for a writ of habeas corpus for lack of jurisdiction. On appeal, the petitioner claims that the court improperly disposed of his petition because it (1) incorrectly concluded that it lacked jurisdiction and (2) failed to conduct a hearing on that issue prior to disposing of the petition. We disagree with the claims of the petitioner and, accordingly, affirm the judgment.
We begin by setting forth the relevant procedural history. The petitioner currently is serving a sentence of twenty years of incarceration after pleading guilty on April 21, 2009, to three counts of assault in the first degree in violation of General Statutes § 53a-59 (a) (5).
*79On May 11, 2016, the petitioner, representing himself, filed a petition for a writ of habeas corpus.
Therein, the petitioner alleged that on or about August 28, 2011, the respondent, the Commissioner of Correction (commissioner), implemented1 the Risk Reduction Earned Credit (RREC) program pursuant to his authority under General Statutes § 18-98e.2 He stated that the "RREC allowed ... [him] to be awarded time at the discretion of the commissioner ... at the rate of five days per month for participation in programs or activities [and] good conduct and obedience to departmental rules ...." Although the petitioner admitted in his petition that the risk reduction credits were awarded at the commissioner's discretion, he also alleged that he signed an "agreement with department staff" that entitles him to receive five risk reduction credits per month.
*860The petitioner further alleged that on February 1, 2016, the commissioner sent a memo to inmates informing them that he was changing the way he awarded risk reduction credits pursuant to a new policy outlined in Department of Correction, Administrative Directive 4.2A. The directive provided that, thereafter, the amount of credits an inmate would be eligible to receive each month would be based on the inmate's risk classification-a level four inmate could earn up to three days of credit per month, a level two or three inmate could earn up to four days, and a level one inmate could earn up to five days. Moreover, a level four *80inmate could apply to have reinstated the additional two credits per month that he was earning previously.
The petitioner further alleged that he continues to be in compliance with the aforementioned "agreement" and, despite the change in policy, should therefore "be grandfathered [in] to receive five days RREC per month, pursuant to ... § 18-98e." He thus requested the habeas court's intervention and that it "reinstate the RREC of five days per month that [he] signed a contract for ...."
On May 19, 2016, the habeas court, Oliver, J. , disposed of the petition sua sponte pursuant to Practice Book § 23-24 (a) (1)3 because the court lacked subject *81matter jurisdiction over it, citing Petaway v. Commissioner of Correction , 160 Conn. App. 727, 125 A.3d 1053 (2015), cert. dismissed, 324 Conn. 912, 153 A.3d 1288 (2017). The court did not hold a hearing prior to reaching this determination.
The petitioner subsequently filed a petition for certification to appeal from the court's dismissal of his petition on May 31, 2016. On June 1, 2016, the court granted the petitioner's certification to appeal, as well as the petitioner's application for appointment of counsel. The petitioner timely filed the present appeal on June 15, 2016.
*861I
We first address the petitioner's claim that the habeas court improperly dismissed his petition because it failed to first hold a hearing on the issue of whether the court had jurisdiction.4 The petitioner argues that, pursuant to this court's holding in Boyd v. Commissioner of Correction , 157 Conn. App. 122, 115 A.3d 1123 (2015), the habeas court cannot dismiss a petition sua sponte without fair notice to the petitioner and a hearing. We disagree.
In Boyd , this court concluded that it is an abuse of discretion for a habeas court to dismiss a petition sua sponte and without a hearing pursuant to its authority under Practice Book § 23-29 unless the petition "alleges the same grounds for relief sought in a previously denied petition, and fails to allege new facts or evidence ...." Id., at 125, 115 A.3d 1123. In the present case, however, unlike in *82Boyd , the court concluded that it lacked jurisdiction over the petition pursuant to its authority under Practice Book § 23-24,5 rather than Practice Book § 23-29. Thus, we must determine whether Practice Book § 23-24 requires the court to hold a hearing prior to concluding that it lacks jurisdiction over the habeas petition.
This issue presents a question of law subject to plenary review. See Menard v. Willimantic Waste Paper Co. , 163 Conn. App. 362, 367, 134 A.3d 1248, cert. denied, 321 Conn. 907, 135 A.3d 279 (2016). In determining whether the court was required to hold a hearing, we first consider the language of the provision itself. See Rivers v. New Britain , 288 Conn. 1, 10-11, 950 A.2d 1247 (2008). Practice Book § 23-24 (a) states: "The judicial authority shall promptly review any petition for a writ of habeas corpus to determine whether the writ should issue. The judicial authority shall issue the writ unless it appears that: (1) the court lacks jurisdiction; (2) the petition is wholly frivolous on its face; or (3) the relief sought is not available." Practice Book § 23-24 (b) provides: "The judicial authority shall notify the petitioner if it declines to issue the writ pursuant to this rule." Thus, there is nothing in the language of Practice Book § 23-24 that requires the court to hold a hearing before disposing of the petition for lack of jurisdiction.
In our view, Practice Book § 23-24 is intended to permit a habeas court to conduct a preliminary review of a petition prior to further adjudication of the writ to weed out those petitions the adjudication of which would be a waste of precious judicial resources either *83because the court lacks jurisdiction over it, the petition is wholly frivolous, or it seeks relief that the court simply cannot grant. We reach this conclusion for two reasons. First, the language of the rule plainly contemplates that the habeas court notify the petitioner of its actions after it reaches a decision on whether the case should proceed further. See Practice Book § 23-24 (b). If the rule were intended to impose a hearing requirement, the drafters would undoubtedly *862have inserted language requiring that the petitioner be notified before the court took such actions.
Second, requiring the habeas court to appoint counsel for a petitioner and hold a hearing over this class of petitions would constitute a considerable drain of state resources and frustrate the habeas court's ability to focus on those petitions that are worthy of adjudication. It is indisputable that the high volume of habeas petitions has been an ongoing source of concern for policymakers and has prompted legislative reforms in recent years. See Public Acts 2012, No. 12-115; 55 H.R. Proc., Pt. 5, 2012 Sess., pp. 1587-91, remarks of Representative Gerald M. Fox III; see also 55 H.R. Proc., supra, p. 1591 ("one of the things that I always thought of when I heard about ... [habeas corpus reform] is that all parties felt that there was a way to do this better and that there's a way to make sure that we can focus on those claims ... that do have merit, that are potentially legitimate and weed out those claims that seem to be bogging down the process and using up a lot of resources where the end result, in all likelihood, would be nothing would come of it"). We therefore decline to graft a hearing requirement onto Practice Book § 23-24 in the absence of language mandating such a procedure.6
*84The petitioner has presented no authority on appeal, from either this court or our Supreme Court, interpreting Practice Book § 23-24 as requiring the habeas court to hold a hearing before declining to issue the writ-nor has our review revealed any such authority. In light of the lack of authority to the contrary and the apparent policy reason underlying Practice Book § 23-24, and because the language of Practice Book § 23-24 does not explicitly require the court to hold a hearing before exercising its authority pursuant to that provision, we conclude that the petitioner was not entitled to a hearing in the present case.
II
Next, we address the petitioner's claim that the habeas court improperly dismissed his petition because it incorrectly concluded that it did not have jurisdiction. The petitioner argues that although the award of risk reduction credits ordinarily does not implicate an inmate's liberty interest because of the discretionary nature of the RREC program, he has a contractual right to such credits in this case that vitiates the discretionary nature of the program. He further argues that, because the commissioner's breach of this contract "bears directly on the duration of his sentence," he has invoked the jurisdiction of the habeas court. For the reasons set forth herein, we conclude that the court properly disposed of the petition because it lacked jurisdiction over it.
We begin with the applicable standard of review and relevant legal principles. "Our Supreme Court has long held that because [a] determination regarding a trial court's subject matter jurisdiction is a question of law, our review is plenary.... Moreover, [i]t is a fundamental rule that a court may raise and review the issue of subject matter jurisdiction at any time.... Subject matter jurisdiction involves the authority of the court *85to adjudicate the type of controversy presented by the action before it.... [A] court lacks discretion to consider the merits of a case over which it is without jurisdiction .... The *863subject matter jurisdiction requirement may not be waived by any party, and also may be raised by a party, or by the court sua sponte, at any stage of the proceedings, including on appeal." (Internal quotation marks omitted.) Pentland v. Commissioner of Correction , 176 Conn. App. 779, 784-85, 169 A.3d 851, cert. denied, 327 Conn. 978, 174 A.3d 800 (2017).
With respect to the habeas court's jurisdiction, "[t]he scope of relief available through a petition for habeas corpus is limited. In order to invoke the trial court's subject matter jurisdiction in a habeas action, a petitioner must allege that he is illegally confined or has been deprived of his liberty." (Internal quotation marks omitted.) Joyce v. Commissioner of Correction , 129 Conn. App. 37, 41, 19 A.3d 204 (2011). In other words, "a petitioner must allege an interest sufficient to give rise to habeas relief." (Internal quotation marks omitted.) Perez v. Commissioner of Correction , 326 Conn. 357, 368, 163 A.3d 597 (2017). "In order to ... qualify as a constitutionally protected liberty [interest] ... the interest must be one that is assured either by statute, judicial decree, or regulation." (Emphasis omitted; internal quotation marks omitted.) Fuller v. Commissioner of Correction , 144 Conn. App. 375, 378, 71 A.3d 689, cert. denied, 310 Conn. 946, 80 A.3d 907 (2013).
We turn now to the petitioner's claim. At the outset, we note that because this appeal arises from the habeas court's ruling declining to issue the writ pursuant to Practice Book § 23-24, which is akin to dismissal of the petition "on the basis that the court lacked jurisdiction, we take the facts to be those alleged in the petition, including those facts necessarily implied from the allegations, construing them in favor of the petitioner for *86purposes of deciding whether the court has subject matter jurisdiction." (Internal quotation marks omitted.) Vitale v. Commissioner of Correction , 178 Conn. App. 844, 850, 178 A.3d 418 (2017), cert. denied, 328 Conn. 923, 181 A.3d 566 (2018) ; see also Pentland v. Commissioner of Correction , supra, 176 Conn. App. at 782, 169 A.3d 851 ("[i]n deciding whether to sua sponte dismiss the petitioner's habeas petition, the court was required ... to take the facts to be those alleged in the petition").
The petitioner alleged that he is being deprived of risk reduction credits to which he is entitled, and thereby is being forced to serve a sentence of longer duration. In order to determine whether the court had jurisdiction, therefore, we must decide whether the petitioner has a constitutionally protected liberty interest in the risk reduction credits.
In his petition, the petitioner identified § 18-98e as the source of the commissioner's authority to implement the RREC program. Section 18-98e(a) states that "any person sentenced to a term of imprisonment for a crime committed on or after October 1, 1994 ... 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 ...." (Emphasis added.) Pursuant to § 18-98e, then, an inmate is not guaranteed a certain amount of risk reduction credits per month-or, in fact, any credits at all. Rather, the statute provides only that an inmate may be eligible to receive credits if the commissioner so chooses.
The fact that the commissioner is vested with such broad discretion in implementing the RREC program is significant. Our appellate courts have concluded, consistently, that an inmate does not have a constitutionally protected liberty interest in certain benefits-such as good time credits, risk reduction credits, and early *87parole consideration-if the statutory scheme *864pursuant to which the commissioner is authorized to award those benefits is discretionary in nature.
For example, in Abed v. Commissioner of Correction , 43 Conn. App. 176, 682 A.2d 558, cert. denied, 239 Conn. 937, 684 A.2d 707 (1996), the petitioner filed a habeas petition challenging "the prospective denial of statutory good time credits." Id., at 178, 682 A.2d 558. Prior to the filing of the petition, the commissioner administered a policy pursuant to which an inmate who was classified as a "safety threat" was precluded from earning good time credits. Id. The commissioner sought dismissal of the petition on the ground that the court lacked jurisdiction because the petitioner failed to raise a legally cognizable claim. Id., at 178-79, 682 A.2d 558. The habeas court determined that the petitioner "had a justifiable expectation of earning good time credits based on the plain reading of" General Statutes § 18-7a(c), but disposed of the petition on other grounds. (Internal quotation marks omitted.) Id., at 179, 682 A.2d 558.
On appeal in Abed , this court considered whether "the petitioner ha[d] alleged a liberty interest in good time credits he ha[d] not yet earned so as to raise a legally cognizable claim in his petition." Id., at 180, 682 A.2d 558. This court reasoned that the petitioner's claim that the habeas court had jurisdiction to consider the merits of his petition "succeed[ed] only if the awarding of good time in Connecticut is mandatory." Id. The plain language of § 18-7a(c), however, provided that "the commissioner may award good time credits at his discretion ." (Emphases altered.) Id. We therefore concluded that "because § 18-7a(c) does not require the commissioner to award good time credits, that section cannot create a liberty interest on which the petitioner may predicate habeas corpus relief." Id., at 180-81, 682 A.2d 558 ; see also Beasley v. Commissioner of Correction , 50 Conn. App. 421, 434, 435, 718 A.2d 487 (1998) (directive that *88precluded inmate in administrative segregation from earning statutory good time credits was proper use of commissioner's authority; § 18-7a [c] allowed commissioner to award credits at his discretion, so "[t]o conclude otherwise would render the discretionary nature of § 18-7a [c] superfluous"), aff'd, 249 Conn. 499, 733 A.2d 833 (1999).
Our Supreme Court considered a similar claim in Perez v. Commissioner of Correction , supra, 326 Conn. at 357, 163 A.3d 597. In that case, the petitioner filed a petition for a writ of habeas corpus challenging a statutory amendment to General Statutes § 54-125a that "eliminated the language [of the earlier version of that statute] that permitted [an inmate's] parole eligibility date to be advanced by the application of any earned risk reduction credit." Id., at 365, 163 A.3d 597. The habeas court dismissed the petition, finding that it lacked subject matter jurisdiction. Id., at 366, 163 A.3d 597. On appeal, our Supreme Court concluded that the basis for the court's dismissal was improper but that it nevertheless lacked jurisdiction to consider the merits of the petition for other reasons. Id., at 368, 374, 163 A.3d 597.
Specifically, our Supreme Court determined in Perez that the habeas court lacked jurisdiction because the petitioner did not have a liberty interest in early parole eligibility or risk reduction credits. Id., at 370-73, 163 A.3d 597. It noted that "parole eligibility under § 54-125a does not constitute a cognizable liberty interest sufficient to invoke habeas jurisdiction.... [T]he decision to grant parole is entirely within the discretion of the [Board of Pardons and Paroles]." (Citation omitted; emphasis added; internal quotation marks omitted.) Id., at 371, 163 A.3d 597. It further noted that, "[w]ith respect to the risk *865reduction 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 [commissioner] at any time *89in the [commissioner's] discretion for good cause during the petitioner's period of incarceration. The petitioner, in his brief, disputes that the award or revocation of risk reduction credit is wholly discretionary .... The petitioner's position, however, is manifestly contradicted by the plain language of § 18-98e(a).... Although the legislature has provided guidance to the [commissioner] as to how to exercise his discretion, the [commissioner] still has broad discretion 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." (Internal quotation marks omitted.) Id., at 372, 163 A.3d 597 ; see also Petaway v. Commissioner of Correction , supra, 160 Conn. App. at 734, 125 A.3d 1053 (petitioner had no liberty interest in early parole eligibility because statute gave commissioner discretion in granting inmates parole).
Thus, as precedent from this court and our Supreme Court makes clear, the petitioner in the present case does not have a liberty interest in risk reduction credits because, as the petitioner himself admitted in his petition, the commissioner has broad discretion to implement the RREC program. The petitioner fails on appeal to set forth any persuasive authority that rebuts this conclusion.7 Instead, his sole argument is that the commissioner somehow altered the discretionary nature of *90the RREC program by entering into a binding contract with the petitioner, pursuant to which he is entitled to receive five days of risk reduction credit per month. We disagree.
To begin, we note that "[i]t is the established policy of the Connecticut courts to be solicitous of [self-represented] litigants and, when it does not interfere with the rights of the other parties, to construe the rules of practice liberally in favor of the [self-represented] party." (Internal quotation marks omitted.) Vitale v. Commissioner of Correction , supra, 178 Conn. App. at 850, 178 A.3d 418. The petition for a writ of habeas corpus, however, is still "essentially a pleading and, as such, it should conform generally to a complaint in a civil action.... The principle that a plaintiff may rely only upon what he has alleged is basic.... It is fundamental in our law that the right of a plaintiff to recover is limited to the allegations of his complaint.... [T]he habeas court ... does not have the discretion to look beyond the pleadings ...." (Internal quotation marks omitted.) Id., at 851, 178 A.3d 418. Moreover, although the habeas court must accept all well pleaded facts as true, it "need not admit legal conclusions or the truth or accuracy of opinions stated in the pleadings." (Internal quotation marks omitted.) Coleman v. Commissioner of Correction , 137 Conn. App. 51, 56, 46 A.3d 1050 (2012).
*866The petitioner's assertion that the agreement he was referring to in his petition constitutes a binding contract is a legal conclusion unsupported by any facts alleged in the petition. The petitioner failed to identify the alleged contract, attach it to the petition for the court's consideration, or cite any language from it that would demonstrate that he is entitled to receive five days of risk reduction credit per month. Thus, there was no basis from which the court could have concluded that the agreement was a binding contract.
*91The petitioner argues for the first time on appeal that the agreement he referenced in his petition is his Offender Accountability Plan (OAP) and that his OAP is a contract.8 Again, nothing in the petition supports this assertion-the petitioner never once referenced his OAP or attached it to the petition for the court's consideration. Likewise, he has failed to set forth any authority on appeal that would support the conclusion that an OAP is a contract.
Moreover, even if the petitioner had properly alleged a breach of contract claim against the commissioner, it would not have been enough to invoke the habeas court's jurisdiction because the petitioner, at best, has a contractual interest in such credits rather than a constitutionally protected liberty interest. See Perez v. Commissioner of Correction , supra, 326 Conn. at 372, 163 A.3d 597 (The commissioner "has broad discretion 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.").
Finally, we doubt that the commissioner has the statutory authority to enter into an agreement with an inmate that strips the commissioner of his discretion in the future administration of the RREC program. Such action would contravene the plain language of the statute and frustrate the legislature's clear intent that the *92RREC program be discretionary in nature. See Beasley v. Commissioner of Correction , supra, 50 Conn. App. at 435, 718 A.2d 487. Thus, for all the reasons stated herein, we conclude that the court properly disposed of the habeas petition for lack of jurisdiction.9
The judgment is affirmed.
In this opinion the other judges concurred.
