Opinion

This appeal concerns the denial of a motion to intervene in an action involving the alleged sexual abuse of a child. Because that action has been withdrawn, we dismiss the appeal as moot.

The relevant facts are not in dispute. In the spring of 2005, the plaintiff, John Doe,1 commenced a civil action against the defendants, the Hartford Roman Catholic Diocesan Corporation (diocese), Saint Augustine Church of North Branford (church) and Daniel McSheffery. The complaint sought damages for, inter alia, sexual abuse allegedly suffered at the hands of a priest. On May 25, 2005, Roger J. Frechette filed a motion to intervene in the matter.2 The plaintiff subsequently filed an opposition to the motion to invervene, which the court sustained. Frechette thereafter filed a *498motion to reargue his motion to intervene, which the court denied on September 1, 2005. On September 19, 2005, Frechette filed an appeal from that judgment; he then filed a motion for permission to file a corrected appeal on September 22, 2005. On December 5, 2005, the plaintiff withdrew the entire action against the defendants. This court granted Frechette’s motion to file a corrected appeal from the denial of his motion to intervene on December 8, 2005, which he filed on December 12, 2005.

Prior to oral argument, we ordered the parties to file supplemental briefs on, inter alia, the issue of whether the appeal is moot due to the withdrawal of the underlying action.3 In addition, we permitted the Connecticut Trial Lawyers Association and the Survivors Network of Those Abused by Priests to file an amicus curiae brief.

“Mootness implicates [the] court’s subject matter jurisdiction and is thus a threshold matter for us to resolve. ... It is a well-settled general rule that the existence of an actual controversy is an essential requisite to appellate jurisdiction; it is not the province of appellate courts to decide moot questions, disconnected from the granting of actual relief or from the determination of which no practical relief can follow. ... An actual controversy must exist not only at the time the appeal is taken, but also throughout the pen-dency 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.” (Internal quotation marks omitted.) Giaimo v. New Haven, 257 Conn. 481, 492-93, 778 A.2d 33 (2001).

*499The plaintiff withdrew the underlying action on December 5, 2005. That development is dispositive of the present appeal. Under Connecticut law, withdrawal of the action underlying an appeal from the denial of a motion to intervene renders the appeal moot.4 Commissioner of Revenue Services v. Estate of Culpeper, 4 Conn. App. 249, 250, 493 A.2d 297 (1985); see also Jones v. Ricker, 172 Conn. 572, 576, 375 A.2d 1034 (1977).

Frechette argues that his claim implicates the capable of repetition, yet evading review exception to the mootness doctrine as enunciated in Loisel v. Rowe, 233 Conn. *500370, 660 A.2d 323 (1995). To qualify for review under that exception, an otherwise moot question must meet 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.” Id., 382-83.

To satisfy the first requirement, the challenged action must possess “an intrinsically limited lifespan.” Id., 383. As the Loisel court explained, “[i]f 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.” Id., 383-84. The present action lacks that prerequisite to review. While the plaintiff in this particular action chose to withdraw the action, he was under no compulsion to do so. Future litigants in a similar proceeding likewise will be free either to withdraw their respective actions or to proceed to trial. Put simply, this action involves no functionally insurmountable time constraints.

We further conclude that the challenged action fails to satisfy the second requirement of the capable of repetition, yet evading review exception. Analysis under that requirement “entails two separate inquiries: (1) whether the question presented will recur at all; and (2) whether the interests of the people likely to be affected by the question presented are adequately represented in the current litigation.” Id., 384. Commonly *501referred to as the “surrogacy concept,” that second inquiry requires “some nexus between the litigating party and those people who may be affected by the court’s ruling in the future.” Id., 386. No such nexus is present here. While it did not precisely define the contours of the surrogacy concept, the Loisel court stated that “a public interest advocacy group purporting to litigate on behalf of, without actually representing, any of the affected parties” certainly would be excluded. Id., 387. Frechette is, in many respects, akin to a public interest advocacy group. He appears pro se in this litigation, as he has done previously in other-civil actions of a similar nature. He characterizes his attempted intervention as one “of prime public importance . . . .” Moreover, his attempted intervention is predicated on statutory defenses he seeks to assert on behalf of the diocese and church. Frechette represents none of the affected parties; his involvement in the action is, in the words of the Loisel court, “completely divorced from the relevant parties . . . .” Loisel v. Rowe, supra, 233 Conn. 387. As such, the necessary nexus is lacking.

We conclude that the issue before the court is not capable of repetition, yet evading review and, therefore, does not qualify for review under that exception to the mootness doctrine. Accordingly, this court lacks jurisdiction to entertain the appeal.

The appeal is dismissed.
