*378Following the habeas court's granting of certification to appeal, the petitioner, Latuan Gainey, appeals from the judgment of the habeas court sua sponte dismissing his petition for a writ of habeas corpus. On appeal, the petitioner claims that the habeas court abused its discretion by dismissing his petition for a writ of habeas corpus pursuant to the prior pending action doctrine. We dismiss the appeal as moot.
The following procedural history is relevant to our resolution of this appeal. On March 17, 2015, the petitioner pleaded guilty to the charges pending against him in two consolidated criminal files in Waterbury for offenses he committed on March 20, 2014, and May 20, *3792012.1 At that *786time, the petitioner was sentenced to serve concurrent sentences of two and one-half years incarceration and seven years of special parole.2
On April 7, 2015, the petitioner filed a self-represented petition for a writ of habeas corpus (first petition).3 On September 11, 2015, the petitioner was released from incarceration and began serving his term of special parole. On September 23, 2015, the petitioner was arrested and charged with risk of injury to a child in violation of General Statutes § 53-21 and assault in the third degree in violation of General Statutes § 53a-61 for incidents that took place one day after he was released from prison. In his brief on appeal, the petitioner represents that on September 24, 2015, he was served with a notice of parole violation by the Board of Pardons and Paroles (parole board) on the basis of his failure to register with the state police deadly offender registry unit and his September 23, 2015 arrest.
On December 8, 2015, the petitioner pleaded guilty to one count of breach of peace in the second degree for incidents that occurred on September 20, 2015, and received an unconditional discharge. The petitioner appeared before the parole board for an evidentiary hearing on December 28, 2015. The parole board found *380that the petitioner had violated the conditions of his release and the terms of his special parole. See footnote 1 of this opinion. The parole board, therefore, sentenced the petitioner to incarceration for two years and six months of his remaining seven year term of special parole.
On September 26, 2016, the petitioner filed a self-represented petition for a writ of habeas corpus (second petition), which is the petition at issue in the present appeal.4 On September 29, 2016, the habeas court sua sponte dismissed the second petition on the basis of the prior pending action doctrine.5 See *787Practice Book § 23-29 (5).6 The habeas court granted the petition for *381certification to appeal from the judgment dismissing the second petition.
The petitioner appealed, claiming that the habeas court committed legal error by dismissing his second petition under the prior pending action doctrine and that he was entitled to a hearing on his second petition before it could be dismissed. While the appeal was pending in this court, but before oral argument had occurred, the petitioner completed the term of imprisonment imposed by the parole board for the petitioner's violation of special parole on September 11, 2015. Thus, during oral argument, the respondent, the Commissioner of Correction, suggested that the appeal was moot. Following oral argument, we sua sponte ordered the parties to provide certain information and submit simultaneous supplemental briefs addressing whether the petitioner's appeal was moot.7
In their responses to our sua sponte order, the parties agree that the petitioner has completed the term of his *382reincarceration, has been readmitted to special parole, and is now residing in a halfway house in Waterbury.8 In his supplemental brief, the respondent argues that the appeal is moot because the remedy the petitioner sought in his second petition was release from incarceration and to be readmitted to special parole, which has taken place. Consequently, he asserts, there is no practical relief that this court can grant the petitioner. The respondent also argues that the issue on appeal is not subject to the capable of repetition, yet evading review exception to the mootness doctrine. See Loisel v. Rowe , 233 Conn. 370, 378, 660 A.2d 323 (1995).
In his supplemental brief, the petitioner acknowledges that he has been readmitted *788to special parole but argues that the appeal is not moot because he is still in the custody of the respondent and his special parole will not end until September 9, 2022. Although the petitioner is correct that he is still in the custody of the respondent and his special parole will not expire for some years, that is not the issue with respect to the appeal. In his second petition, the petitioner challenged the parole board's finding that he had violated his special parole and sentenced him to incarceration. The relief he sought pursuant to the second petition was to be released from incarceration and readmitted to special parole. Due to the passage of time, the petitioner has been released from incarceration and is now on special parole, living in a halfway house. Therefore, because the petitioner obtained the relief he sought, there is no practical relief this court can afford him and his appeal is moot.
"Mootness implicates the subject matter jurisdiction of this court. ... We will not decide questions where there exists no actual controversy or where no actual or practical relief can follow from our determination *383.... An actual controversy must exist not only at the time the appeal is taken, but also throughout the pendency of the appeal.... Moreover, [w]hen, during the pendency of an appeal, events have occurred that preclude an appellate court from granting any practical relief through its disposition of the merits, a case has become moot."

(relief originally sought by plaintiff was decision transferring him to less restrictive hospital, and because plaintiff since obtained requested relief, appeal was moot).
In his supplemental brief, the petitioner argues that the issue on appeal is subject to the capable of repetition, yet evading review exception to the mootness doctrine. We disagree.
"To qualify under this exception, an otherwise moot question must satisfy the following three requirements: First, the challenged action, or the effect of the challenged action, by its very nature, must be of a limited duration so that there is a strong likelihood that the substantial majority of cases raising a question about its validity will become moot before appellate litigation can be concluded. Second, there must be a reasonable likelihood that the question presented in the pending case will arise again in the future, and that it will affect either the same complaining party or a reasonably identifiable group for whom that party can be said to act as surrogate. Third, the question must have some public importance. Unless all three requirements are met, the appeal must be dismissed as moot." (Internal quotation marks omitted.) We the People of Connecticut, Inc. v. Malloy , 150 Conn. App. 576, 583, 92 A.3d 961, cert. denied, 314 Conn. 919, 100 A.3d 850 (2014) ; see also Loisel v. Rowe , supra, 233 Conn. at 382-83, 660 A.2d 323.
*384"The first element in the analysis pertains to the length of the challenged action." Loisel v. Rowe , supra, 233 Conn. at 383, 660 A.2d 323. "If an action or its effects is not of inherently limited duration, the action can be reviewed the next time it arises, when it will present an ongoing live controversy. Moreover, if the question presented is not strongly likely to become moot in the substantial majority of cases in which it arises, the urgency of deciding the pending case is significantly reduced.... [A] party typically satisfies this prong if there exists a functionally insurmountable time [constraint] ...." (Citations omitted; internal quotation *789marks omitted.) Patterson v. Commissioner of Correction , 112 Conn. App. 826, 835-36, 964 A.2d 1234 (2009).
In the present appeal, the exception to the mootness doctrine requires that there be a functionally insurmountable time constraint inherent in dismissing a petition for a writ of habeas corpus for a petitioner who has been incarcerated for a portion of his term of special parole; additionally, the time constraint must create a strong likelihood that a substantial majority of cases challenging the dismissal of the petition under the prior pending action doctrine will become moot before the appeal is resolved. A petitioner whose special parole has been revoked faces imprisonment over the term of special parole that may vary in length from a minimum of one year to a maximum of ten years per offense. For certain crimes, and under certain circumstances, the term of special parole may be longer. See General Statutes § 54-125e (c) ;9 see *385also State v. Brown , 310 Conn. 693, 710, 80 A.3d 878 (2013) (legislature has not expressed intention to prevent trial court from imposing sentences of special parole consecutively). Consequently, given the range of possible sentences for a parole violation, it is unlikely that a substantial majority of the appellate cases that contest the habeas court's dismissal, under the prior pending action doctrine, of a petition for a writ of habeas corpus seeking release from incarceration following the parole board's revocation of special parole will become moot as the result of the petitioner's completing the term of reimprisonment before the appeal is resolved. The petitioner, therefore, has failed to meet the first prong of Loisel. The petitioner's claim does not qualify for review under the capable of repetition, yet evading review exception to the mootness doctrine, because it cannot satisfy Loisel 's three requirements required for review.10 See We the People of Connecticut, Inc. v. Malloy , supra, 150 Conn. App. at 583, 92 A.3d 961. For the foregoing reasons, we dismiss the appeal as moot.
The appeal is dismissed.
In this opinion the other judges concurred.
