The petitioner, Bryan Jordan, appeals from the judgment of the habeas court dismissing his petition for a writ of habeas corpus for lack of subject matter jurisdiction and for the failure to state a claim upon which habeas relief can be granted. The petitioner's sole claim on appeal is that the habeas court improperly dismissed his claim that the respondent, the Commissioner of Correction, entered into, and subsequently breached, a purported contract with the petitioner to award him risk reduction credit in exchange for his adherence to his offender accountability plan. We disagree and, accordingly, affirm the judgment of the habeas court.

The following facts and procedural history are relevant to the resolution of this appeal. The petitioner was found guilty, following a jury trial, of manslaughter in the first degree with a firearm in violation of General Statutes § 53a-55a (a) and carrying a pistol or revolver without a permit in violation of General Statutes § 29-35 (a). The charges stemmed from a shooting death that occurred on September 19, 2005. See State v. Jordan , 117 Conn. App. 160 , 161, 978 A.2d 150 , cert. denied, 294 Conn. 904 , 982 A.2d 648 (2009). On April 27, 2007, the petitioner was sentenced to a total effective sentence of forty-five years of incarceration. 1 The petitioner's conviction was upheld on direct appeal by this court. See id.

Thereafter, the then self-represented petitioner initiated this action by filing a petition for a writ of habeas corpus. On November 6, 2017, the petitioner, after obtaining counsel, filed the operative amended petition alleging, inter alia, breach of contract. Specifically, the petitioner's breach of contract claim alleges that the respondent, by virtue of having the petitioner sign his offender accountability plan, agreed to award the petitioner five days of risk reduction credit per month in exchange for the petitioner's adherence to the offender accountability plan. Further, he alleges that, once No. 15-216 of the 2015 Public Acts (P.A. 15-216) came into effect, which rendered the petitioner unable to earn further risk reduction credit, the respondent nonetheless breached the parties' agreement by failing to award further risk reduction credit.

On March 19, 2018, the court, sua sponte, dismissed the amended petition for lack of subject matter jurisdiction and failure to state a claim on which habeas relief could be granted. 2 See Practice Book § 23-29. 3 The court in its memorandum of decision did not address each of the petitioner's counts but, instead, broadly concluded that the court did not have subject matter jurisdiction over the petitioner's claims and that the petitioner had failed to state a claim on which habeas relief could be granted. The court subsequently granted the petition for certification to appeal, which was timely filed in this court. Additional facts will be set forth as necessary.

We begin our analysis with the applicable standards 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 to 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 subject 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.

"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.... In other words, a petitioner must allege an interest sufficient to give rise to habeas relief.... 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." (Citations omitted; internal quotation marks omitted.) Green v. Commissioner of Correction , 184 Conn. App. 76 , 85, 194 A.3d 857 , cert. denied, 330 Conn. 933 , 195 A.3d 383 (2018). "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." (Internal quotation marks omitted.) Perez v. Commissioner of Correction , 326 Conn. 357 , 368, 163 A.3d 597 (2017). "It is well settled that [t]he petition for a writ of habeas corpus is essentially a pleading and, as such, it should conform generally to a complaint in a civil action." (Internal quotation marks omitted.) Pentland v. Commissioner of Correction , 176 Conn. App. 779 , 786, 169 A.3d 851 , cert. denied, 327 Conn. 978 , 174 A.3d 800 (2017). "In reviewing whether a petitioner states a claim for habeas relief, we accept its allegations as true." Coleman v. Commissioner of Correction , 137 Conn. App. 51 , 55, 46 A.3d 1050 (2012). We next turn to a brief discussion of the relevant law pertaining to risk reduction credit.

Pursuant to General Statutes (Rev. to 2011) § 18-98e, the respondent had discretion to award risk reduction credit to reduce an inmate's sentence, up to five days per month, for good conduct. Section 18-98e subsequently was amended, however, by P.A. 15-216, such that inmates convicted of certain violent crimes, including manslaughter in the first degree with a firearm, are no longer eligible to earn future risk reduction credit. 4 Both our Supreme Court and this court have consistently held that an inmate does not have a cognizable liberty interest in earning future risk reduction credit. See Perez v. Commissioner of Correction , supra, 326 Conn. at 370-73 , 163 A.3d 597 ; Rivera v. Commissioner of Correction , 186 Conn. App. 506 , 514, 200 A.3d 701 (2018), cert. denied, 331 Conn. 901 , 201 A.3d 402 (2019) (collecting cases). With these legal principles in mind, we now turn to the petitioner's claim.

The petitioner argues that his claim that the respondent breached a contract by failing to award him risk reduction credit in exchange for adherence to his offender accountability plan implicates a cognizable liberty interest sufficient to invoke the court's subject matter jurisdiction. The petitioner does not dispute our well established jurisprudence that there is no liberty interest in risk reduction credit. See Perez v. Commissioner of Correction , supra, 326 Conn. at 370-73 , 163 A.3d 597 . Rather, the petitioner essentially argues that he has a contractual interest in earning risk reduction credit by virtue of his alleged agreement with the respondent to adhere to his offender accountability plan in exchange for risk reduction credit. 5 To bolster this claim, the petitioner argues that, pursuant to Santobello v. New York , 404 U.S. 257 , 92 S. Ct. 495 , 30 L. Ed. 2d 427 (1971), his breach of contract claim is sufficient to invoke the court's subject matter jurisdiction. We do not find Santobello to be applicable in the present case. 6 In Santobello , the defendant agreed to plead guilty to a lesser offense if the prosecutor agreed not to make a recommendation as to the length of the defendant's sentence. Id., at 258 , 92 S. Ct. 495 . At the time of the defendant's sentencing, a different prosecutor, who was unaware of the plea agreement, recommended the maximum sentence, which the court imposed, in violation of the agreement. Id., at 259 , 92 S. Ct. 495 . The court held that a prosecutor has an obligation to honor a plea agreement with a criminal defendant. Id., at 262 , 92 S. Ct. 495 . Central to the court's holding was the importance of plea bargaining to our judicial system and the need to ensure fairness during that phase of the judicial process. Id. ("[t]his [plea bargaining] phase of the process of criminal justice, and the adjudicative element inherent in accepting a plea of guilty, must be attended by safeguards to insure the defendant what is reasonably due in the circumstances").

By contrast, in the present case, the alleged agreement between the petitioner and the respondent did not take place during the plea bargaining process, but, rather, after the petitioner had been convicted and was incarcerated. Thus, the concerns regarding fairness during the plea bargaining process are not present here as they were in Santobello . Moreover, our reading and application of Santobello in the present case is consistent with our prior holding in Green v. Commissioner of Correction , supra, 184 Conn. App. at 84 , 194 A.3d 857 , in which this court addressed a petitioner's claim that he entered into a binding contract with the respondent that allegedly conferred on him a contractual right to earn risk reduction credit. This court rejected the petitioner's assertion in that case that the respondent, pursuant to Santobello , was required to honor the purported contract because it found that the habeas action "present[ed] a completely different procedural posture" than the plea bargaining process. Id., at 89 , 194 A.3d 857 n.7. Additionally, this court concluded that, even if the petitioner properly had alleged a breach of contract claim against the respondent, 7 a breach of contract claim did not invoke the habeas court's subject matter jurisdiction because "the petitioner, at best, has a contractual interest in such [credit] rather than a constitutionally protected liberty interest." Id., at 91 , 194 A.3d 857 .

The petitioner, citing to Vandever v. Commissioner of Correction , 315 Conn. 231 , 106 A.3d 266 (2014), also argues that his claim raises a valid liberty interest because, if he does not comply with his offender accountability plan, he can potentially receive a disciplinary ticket and, as a result, may be segregated from the general inmate population. In Vandever , our Supreme Court recognized that "prison inmates have a protected liberty interest in avoiding certain conditions of confinement if, pursuant to state statute or regulation, they can be subjected to such conditions only if certain procedural requirements are met, and those conditions impose an atypical and significant hardship in relation to the ordinary incidents of prison life." Id., at 232-33, 106 A.3d 266 . The court therefore examined whether the petitioner in that case had a liberty interest in avoiding administrative segregation and was accordingly afforded due process before his segregation. Id., at 233, 106 A.3d 266 .

In the present case, the petitioner has not been segregated from the general prison population and, as a result, there is no concern that he has not been afforded due process in avoiding segregation. We also find dubious the petitioner's assertion in his appellate brief that, if he had not signed the offender accountability plan, he would not be subject to the same punishment. It defies logic that the respondent would be unable to discipline an inmate for disobedience in the absence of an offender accountability plan. Accordingly, because the petitioner's claim in the present case does not give rise to a cognizable liberty interest, 8 we conclude that the habeas court properly dismissed the petitioner's breach of contract claim for lack of subject matter jurisdiction. 9

The judgment is affirmed.

In this opinion the other judges concurred.
