Opinion
The defendant was charged, in three separate informations brought pursuant to General Stat
*369
utes § 53a-32,
1
with violating the terms of his probation by committing certain criminal offenses. After a hearing, the trial court found that the defendant had violated his probation, revoked his probation, and sentenced him to serve time in prison. The defendant appealed to the Appellate Court claiming that the trial court had: (1) improperly found that he had violated his probation; and (2) abused its discretion in revoking his probation. The Appellate Court dismissed the defendant’s first claim as moot because he had pleaded guilty to the underlying offenses, thereby eliminating any live controversy about his conduct;
State
v.
Preston,
The state then appealed, following our grant of certification, 2 from the judgment of the Appellate Court. In its appeal, the state claims that although the Appellate Court properly dismissed both of the defendant’s claims on appeal as moot, the Appellate Court improperly concluded that the defendant’s guilty plea—which rendered moot the defendant’s claim that he did not violate a term of his probation—did not render moot his second claim that the trial court abused its discretion in the dispositional phase when it revoked his probation. Id., 533. The defendant also appealed from the judgment of the Appellate Court, following our grant of certification, 3 claiming that, although his appeal from the evidentiary phase of the revocation of probation hearing is moot, his appeal from the dispositional phase is not moot under the collateral consequences doctrine. We conclude that the Appellate Court properly determined that the defendant’s claim with regard to the trial court’s exercise of discretion to revoke his probation in the dispositional phase of the revocation of probation proceeding was not rendered moot as a result of his guilty plea. We also conclude that the Appellate Court improperly determined that the defendant’s appeal was moot for lack of a live controversy. Accordingly, we reverse the judgment of the Appellate Court as to the defen *371 dant’s claim that the trial court abused its discretion when it revoked his probation.
The following facts and procedural history are set forth in the Appellate Court’s opinion. “On September 28, 2001, the defendant was convicted of two counts of breach of the peace in the second degree in violation of General Statutes § 53a-181 and violation of probation in violation of ... § 53a-32 and was sentenced to one year incarceration, execution suspended, for breach of the peace and one year incarceration, execution suspended, for violation of probation, followed by two and one-half years of probation. The defendant signed the notice of his conditions of probation on September 28, 2001. The terms of the defendant’s probation included the condition that he not violate any criminal law.”
State
v.
Preston,
supra,
“During the defendant’s period of probation, he was arrested and charged with assault in the first degree in violation of General Statutes § 53a-59, unlawful discharge of a firearm in violation of General Statutes § 53-203, illegal use of a facsimile firearm in violation of General Statutes § 53-206c (c) and carrying a pistol without a permit in violation of General Statutes § 29-35 (a).” Id. Following his arrest, on September 18, 2002, the defendant was charged in three separate informations with violating the terms of his probation, in violation of § 53a-32. “On March 20, 2003, a revocation of probation hearing was held in which the court found that the defendant had violated the conditions of his probation. The court revoked the defendant’s probation and sentenced him to an effective term of two years incarceration, which was the maximum sentence for the violation.” Id.
The defendant then appealed from the judgment of the trial court to the Appellate Court, claiming “that the [trial] court (1) improperly found violations of pro
*372
bation and (2) abused its discretion in revoking his probation.” Id., 528. While the defendant’s appeal before the Appellate Court was pending, “the defendant pleaded guilty to attempt to commit assault in the first degree in violation of General Statutes §§ 53a-49 (a) (2) and 53a-59 (a) (5) and conspiracy to commit assault in the first degree in violation of General Statutes §§ 53a-48 (a) and 53a-59 (a) (5)____” Id., 529-30. “The defendant was sentenced to six years incarceration with five years special parole to run concurrently with his outstanding sentence.” Id., 530. On September 14, 2005, the Appellate Court dismissed as moot the defendant’s first claim, that the trial court improperly had found violations of probation, because the defendant’s guilty plea had “eliminat[ed] any controversy as to whether he had engaged in the criminal conduct that gave rise to his violation of probation.” Id., citing
State
v.
Singleton,
The Appellate Court then turned to the defendant’s only remaining claim on appeal, that the trial court had abused its discretion when it revoked the defendant’s probation.
State
v.
Preston,
supra,
On appeal, the state challenges the rationale for the Appellate Court’s determination that the defendant’s appeal was moot. Specifically, the state claims that the Appellate Court improperly rejected the state’s argument that the defendant’s appeal from the revocation of his probation was moot because he had pleaded guilty to the underlying offenses. 4 The defendant challenges the Appellate Court’s determination that his appeal from the judgment of the trial court revoking his probation is moot under the collateral consequences doctrine. We agree with the defendant.
We begin with the standard of review. “Mootness is a question of justiciability that must be determined as a threshold matter because it implicates [this] court’s subject matter jurisdiction .... We begin with the
*374
four part test for justiciability established in
State
v.
Nardini,
“The mootness doctrine is rooted in the first factor of the Nardini test. ... It is founded on the same policy interests as the doctrine of standing, namely, to assure the vigorous presentation of arguments concerning the matter at issue. . . . This court recently reiterated that the standing doctrine is designed to ensure that courts and parties are not vexed by suits brought to vindicate nonjusticiable interests and that judicial decisions which may affect the rights of others are forged in hot controversy, with each view fairly and vigorously represented. . . . Indeed, we note that courts are called upon to determine existing controversies, and thus may not be used as a vehicle to obtain advisory judicial opinions on points of law. . . .
“[A]n actual controversy must exist not only at the time the appeal is taken, but also throughout the pendency of the appeal. . . . When, 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.” (Citations omitted; internal quotation marks omitted.) Id., 767.
*375 I
We first turn to the state’s claim that, although the Appellate Court properly dismissed the defendant’s appeal as moot, it did so for improper reasons. The state contends that our decision in
Singleton
requires that, when a defendant challenges the outcome of both the evidentiary phase and dispositional phase of a revocation of probation hearing and subsequently pleads guilty to the underlying offense, the defendant’s
entire
appeal is rendered moot. The state asserts that, under our decisions in
State
v.
Singleton,
supra,
In order to address fully the state’s position, it is helpful to review the principles governing revocation of probation hearings. We have recognized that revocation of probation hearings, pursuant to § 53a-32, are comprised of two distinct phases, each with a distinct purpose. See
State v. Faraday,
Moreover, we previously have recognized that the evidentiary and dispositional phases are governed by two different standards of review.
State
v.
Faraday,
supra,
“The standard of review of the trial court’s decision at the [dispositional] phase of the revocation of probation hearing is whether the trial court exercised its discretion properly by reinstating the original sentence and ordering incarceration. ... In determining whether there has been an abuse of discretion, every reasonable presumption should be given in favor of the correctness of the court’s ruling. . . . Reversal is required only where an abuse of discretion is manifest or where injustice appears to have been done.” (Internal quotation marks omitted.)
State
v.
Faraday,
supra,
The state contends that, despite the language of § 53a-32, the cases that have involved appeals from the distinct phases of a revocation of probation hearing, and the two distinct standards of review that we apply to these two phases, it is improper to distinguish between the two phases of a revocation of probation hearing when a challenge to the evidentiary phase is moot. The state contends that these cases stand for the proposition that, when a defendant appeals from a revocation of probation that is based on criminal conduct, a challenge to the sufficiency of the evidence of the violation and a challenge to the court’s actual revocation present the same issue, namely, whether the trial court abused its discretion in revoking the defendant’s probation, and *378 that this issue becomes moot when there is no live controversy as to whether the defendant violated his probation.
In support of this claim, the state primarily relies on our decision in
Singleton.
In
Singleton,
the defendant filed an appeal in the Appellate Court from the judgment of the trial court revoking his probation.
State
v.
Singleton,
supra,
In its appeal, the state argued that, under
McElveen,
the defendant’s guilty plea rendered his challenge of the trial court’s determination that he had violated the terms of his probation moot. Id., 436, citing
State
v.
McElveen,
supra,
To resolve this inconsistency, we were required in
Singleton
to “overrule the conclusion in
Daniels
that a subsequent conviction of criminal conduct arising out of the same facts underlying a violation of probation does not render the appeal from the violation of probation moot.”
State
v.
Singleton,
supra,
In the present case, the state argues that our conclusion in
Singleton
applies equally to the evidentiary and dispositional phases of the revocation hearing. In support of this claim the state relies on certain language in our decision in
McElveen
suggesting that the issue in that case was whether the trial court properly had revoked the defendant’s probation.
6
A careful reading of
McElveen,
however, reveals that that is not the case.
*380
Although we did not directly address the merits of the defendant’s appeal in
McElveen,
we stated that “the defendant appealed from the judgment of the trial court . . . claiming that the trial court improperly found that
the state had presented sufficient evidence to prove that the had violated the conditions of his probation.”
(Emphasis added.)
State
v.
McElveen,
supra,
Similarly, our decision in
Singleton,
overruling the holding of
Daniels
that a guilty plea in the underlying criminal case does not render moot a claim that the trial court improperly had revoked the defendant’s probation, does not support the state’s position. The only claims in
Daniels
were that the trial court improperly had: (1) found that the state had proved by a preponderance of the evidence that the defendant had violated his probation; and (2) admitted certain evidence of the defendant’s guilt.
State
v.
Daniels,
supra,
We conclude, therefore, that Singleton and McElveen do not answer the question that is presented by the state, namely, whether a circumstance that renders moot a claim arising from the evidentiary phase of a revocation of probation hearing also renders moot any claim arising from the dispositional phase of the hearing. We conclude that it does not. As we have indicated, the trial court’s ruling in the dispositional phase is sub *381 ject to review for abuse of discretion. We have recognized that, in exercising its discretion, the trial court is required to give the defendant’s case individualized consideration, in light of the purpose of probation. 7 Although a finding of abuse of discretion during the dispositional phase will be rare when there is no live controversy as to whether the defendant violated his probation by committing a criminal offense, 8 affirmance of the trial court’s judgment is not a foregone conclusion. 9 We conclude that, when the defendant has raised a claim that the trial court abused its discretion in rendering its judgment during the dispositional phase, practical relief is available even when there is no live *382 controversy as to whether the defendant committed the underlying offense and, therefore, the claim is not moot.
In the present case, the defendant claims that, even if the trial court properly had found that he violated his probation, the trial court abused its discretion in revoking his probation. Accordingly, we conclude that the Appellate Court properly determined that the defendant’s guilty plea to the underlying criminal charges did not render moot his claim that the trial court improperly revoked his probation.
II
We now turn to the defendant’s claim that the Appellate Court improperly dismissed his appeal from the trial court’s judgment revoking his probation because he will suffer collateral consequences as a result of the revocation. We agree.
“[U]nder this court’s long-standing mootness jurisprudence . . . despite developments during the pendency of an appeal that would otherwise render a claim moot, the court may retain jurisdiction when a litigant shows that there is a reasonable possibility that prejudicial collateral consequences will occur.” (Internal quotation marks omitted.)
Wallingford
v.
Dept. of Public Health,
supra,
In
McElveen,
we noted that “a violation of probation carries consequences in connection with future involvement with the criminal justice system, beginning with [the defendant’s] ability to obtain a favorable decision concerning preconviction bail. . . . [T]he failure to abide by conditions of probation is a relevant consideration in the trial court’s decision when setting conditions of release. A defendant’s past probation violation is equally relevant when considering whether to afford a convicted defendant future probation.” (Citations omitted.)
State
v.
McElveen,
supra,
The state asserts, however, that we should adopt the federal standard for collateral consequences, as articu
*384
lated by the United States Supreme Court in
Spencer
v.
Kemna,
The judgment of the Appellate Court is reversed as to the defendant’s claim that the trial court abused its discretion when it revoked his probation and the case is remanded to the Appellate Court for consideration of that claim.
In this opinion the other justices concurred.
Notes
General Statutes § 53a-32 provides in relevant part: “(a) At any time during the period of probation or conditional discharge, the court or any judge thereof may issue a warrant for the arrest of a defendant for violation of any of the conditions of probation or conditional discharge, or may issue a notice to appear to answer to a charge of such violation, which notice shall be personally served upon the defendant. . . . [U]pon an arrest by warrant as herein provided, the court shall cause the defendant to be brought before it without unnecessary delay for a hearing on the violation charges. At such hearing the defendant shall be informed of the manner in which such defendant is alleged to have violated the conditions of such defendant’s probation or conditional discharge, shall be advised by the court that such defendant has the right to retain counsel and, if indigent, shall be entitled to the services of the public defender, and shall have the right to cross-examine witnesses and to present evidence in such defendant’s own behalf.
“(b) If such violation is established, the court may: (1) Continue the sentence of probation or conditional discharge; (2) modify or enlarge the conditions of probation or conditional discharge; (3) extend the period of probation or conditional discharge, provided the original period with any extensions shall not exceed the periods authorized by section 53a-29; or (4) revoke the sentence of probation or conditional discharge. If such sentence is revoked, the court, shall require the defendant to serve the sentence imposed or impose any lesser sentence. Any such lesser sentence may include a term of imprisonment, all or a portion of which may be suspended entirely or after a period set by the court, followed by a period of probation with such conditions as the court may establish. No such revocation shall be ordered, except upon consideration of the whole record and unless such violation is established by the introduction of reliable and probative evidence and by a preponderance of the evidence.”
We certified the following question in the state’s appeal: “Did the Appellate Court properly conclude that the defendant’s appeal from the judgment revoking his probation was moot because the defendant was serving concurrent sentences for (1) the violation of probation and (2) the conviction of attempted assault in the first degree and conspiracy to commit assault in the first degree?”
State
v.
Preston,
We certified the following question in the defendant’s appeal: “Did the Appellate Court properly dismiss the defendant’s appeal from the judgment revoking his probation as moot?”
State
v.
Preston,
We note that the state was not aggrieved by the judgment of the Appellate Court, which was rendered in its favor. See
Seymour
v.
Seymour,
The United States Supreme Court also has recognized that revocation of probation hearings usually consist of an evidentiary phase and a dispositional phase. “In identifying the procedural requirements of due process, we have observed that the decision to revoke probation typically involves two distinct components: (1) a retrospective factual question whether the probationer has violated a condition of probation; and (2) a discretionary determination by the sentencing authority whether violation of a condition warrants revocation of probation.”
Black
v.
Romano,
In McElveen,
we stated: “[t]he defendant. . . appeals from the judgment of the trial court revoking his probation . . .
State
v.
McElveen,
supra,
“A revocation proceeding is held to determine whether the goals of rehabilitation thought to be served by probation have faltered, requiring an end to the conditional freedom obtained by a defendant at a sentencing that allowed him or her to serve less than a full sentence. . . . [T]he ultimate question [in the probation process is] whether the probationer is still a good risk .... This determination involves the consideration of the goals of probation, including whether the probationer’s behavior is inimical to his own rehabilitation, as well as to the safety of the public.” (Internal quotation marks omitted.)
State
v.
Fagan,
supra,
See
State
v.
Fagan,
supra,
The state argues that, because conviction of a felony is a permissible basis for revoking probation, any claim of abuse of discretion by the trial court is necessarily an “exercise in futility.” In support of this proposition, the state contends that “[i]t is universally held that the commission of a felony violates a condition inherent in every probation order.”
