*394 **731 This writ of error is the companion case to Independent Party of CT-State Central v. Merrill , 330 Conn. 681 , 200 A.3d 1118 (2019), in which this court affirmed the judgment of the trial court resolving a long running dispute between the Danbury and Waterbury factions of the state's Independent Party by, inter alia, granting declaratory and injunctive relief directing the named defendant in the underlying action, Secretary of the State Denise W. Merrill (Secretary), to accept only those endorsements made pursuant to the party's 2010 bylaws. The plaintiffs in error, thirteen candidates for the state House of Representatives endorsed by the Danbury faction 1 prior to the issuance of the trial court's decision in the underlying action, brought this writ of **732 error 2 to protect their rights with respect to the judgment of the trial court. The endorsed candidates now argue that their writ of error is moot given the unchallenged decision of the Secretary to accept the Danbury faction's endorsements with respect to twelve of them, thus allowing them to be on the Independent Party's ballot line for the 2018 election. Rebekah Harriman-Stites, a candidate endorsed by the Waterbury faction for the 106th assembly district, however, has appeared in the present proceeding as a defendant in error 3 and contends that the writ of error is not moot in light of her request that we order the Secretary to print her name on the ballot in accordance with the trial court's decision. Because the writ of error is moot, and Harriman-Stites' separate request for relief is not properly before us, we dismiss this writ of error.

The record reveals the following relevant facts and procedural history. 4 In the underlying action, the plaintiffs, the Independent Party of CT-State Central and *395 **733 its officers, Michael Duff, Donna L. LaFrance, and Roger Palanzo, who lead the Danbury faction of the Independent Party, brought an action seeking declaratory and injunctive relief against two defendants, Michael Telesca and Rocco Frank, Jr., who lead its Waterbury faction. 5 The central dispute in the underlying case concerned which of two sets of bylaws govern the Independent Party under General Statutes §§ 9-372 (6) and 9-374 -namely, a set of bylaws that the Danbury faction filed with the Secretary in 2006 (2006 bylaws), or a set filed in 2010 (2010 bylaws), which was drafted after Ralph Nader had received a sufficient number of votes in the 2008 presidential election to afford the Independent Party with statewide minor party status for the first time.

After a three day trial to the court, on August 21, 2018, the trial court, Hon. A. Susan Peck , judge trial referee, 6 issued a lengthy memorandum of decision. With respect to its specific findings of fact and conclusions of law, the trial court first concluded that the 2010 bylaws were controlling under the statutory scheme governing minor parties, in particular §§ 9-372 (6) and 9-374, the "plain language of [which indicates] that a minor party does not exist in Connecticut until it designates a candidate for office who achieves 1 percent of the vote." The trial court further observed that, in contrast to the 2010 bylaws, which were created in a statewide process after Nader's nomination in 2008, the 2006 bylaws were filed with the Secretary at a time when the "party so-named had not achieved minor party status for any statewide office." Thus, the trial court determined that the "2006 bylaws are valid only to the extent they are recognized as such within the local **734 committee. Although the plaintiffs filed the 2006 bylaws with the [Secretary], the filing of these rules merely allowed the [Danbury faction] to nominate local candidates and get them on an official ballot once they had attained 1 percent of the vote for a particular office. The 2006 bylaws did not automatically allow the [Danbury faction] to gain control of the statewide Independent Party after the 2008 presidential election." (Footnote omitted.) Accordingly, the trial court concluded that "the only statewide Independent Party was created post-2008, and the 2010 bylaws are the only valid governing rules of that party." 7 *396 The trial court further concluded that the plaintiffs had "failed to establish by a preponderance of the evidence that they are entitled to the declaratory and injunctive relief requested in their second amended complaint." Instead, the trial court turned to the defendants' counterclaim and special defenses, and concluded that they had "established by a preponderance of the evidence that the 2010 bylaws are the validly adopted and operative bylaws of the Independent Party/Independent Party of Connecticut, filed pursuant to the **735 requirements of § 9-374, and that [Telesca and Frank] are the duly elected officers of the Independent Party/Independent Party of Connecticut, and the individual plaintiffs are not. In addition, the court hereby declares that the 2006 bylaws apply only to the Danbury faction's local committee of the Independent Party. Finally, the court hereby declares and orders that the [Secretary] must accept only the nominations and endorsements of the Independent Party/Independent Party of Connecticut, made pursuant to the 2010 bylaws filed with the [Secretary] on March 22, [2010], or as may be amended, pursuant to ... § 9-374." According to the plaintiffs, this order effectively "gives the Waterbury faction under the leadership of Telesca and Frank control of the statewide ballot line."

Prior to the issuance of the trial court's underlying decision, the Danbury faction published, in the August 15, 2018 edition of the Hartford Courant, notice of the "Independent Party Endorsement Meeting," scheduled for August 20, 2018. On August 20, 2018, the Danbury faction held that endorsement meeting and endorsed certain candidates for the 2018 general election, including each of the endorsed candidates in the present proceeding. On the morning of August 21, 2018, the Danbury faction filed these endorsements with the Secretary. Later that same day, the trial court issued its memorandum of decision.

Given some uncertainty about the effect of the trial court's decision on those endorsements, on September 7, 2018, the endorsed candidates filed this writ of error to preserve their rights. 8 On September 7, 2018, the endorsed candidates also filed motions to intervene in **736 the underlying action, and for declaration of an automatic stay pursuant to Practice Book § 72-3A. 9 *397 The trial court did not take any action on these motions.

Subsequently, on September 11, 2018, the Secretary advised the parties and the individual candidates running for the 106th assembly district, Mitch Bolinsky, who was endorsed by the Danbury faction, and Harriman-Stites, who was endorsed by the Waterbury faction, by certified letter that the Secretary had received competing endorsements for the Independent Party ballot line. The Secretary informed Bolinsky and Harriman-Stites that, consistent with her policy and General Statutes § 9-250, she would not print either of their names as the Independent Party nominee for that office, unless one of them were to withdraw.

Telesca, as chairman of the Waterbury faction, received the letter from the Secretary on September 14, 2018, which was a Friday. That same day, Telesca called Ted Bromley, an attorney with the Secretary's office, and left him a voice mail message. Bromley **737 responded to Telesca with an e-mail stating that he was out of the office and would look into the matter when he returned to the office on Monday. On Thursday, September 20, 2018, not having heard from Bromley, Telesca e-mailed Bromley a letter detailing the trial court's decision in the present case. In that letter, Telesca argued that the only nomination made pursuant to the 2010 bylaws was that of Harriman-Stites, noted that the Waterbury faction had not made any endorsements for certain other House or Probate Judge districts, and concluded that the Secretary must "disregard any nominations that you may have received from the Danbury faction ...." Telesca did not hear further from the Secretary's office.

On September 25, 2018, the Secretary published a list of nominees for the November, 2018 election, which included the twelve endorsed candidates other than Bolinsky, in accordance with the September 11, 2018 letter. Absentee ballots had been printed during the week of September 17, 2018, and were made available in town clerks on October 5, 2018, as required by General Statutes § 9-140. Further, military and overseas ballots were mailed to voters on September 22, 2018.

Shortly thereafter, Harriman-Stites filed a motion to intervene in the underlying action, an objection to the endorsed candidates' motion for an automatic stay, and a caseflow request seeking to have her motion and objection heard along with the other posttrial motions filed by the endorsed candidates. Following a motion for continuance filed by the plaintiffs, to which Harriman-Stites' objected, oral arguments on posttrial motions were rescheduled for October 22, 2018. On October 17, 2018, Harriman-Stites filed a motion for contempt in the trial court against the Secretary, arguing that the court's decision has not been stayed and asking it to find the Secretary "in contempt of the orders of the court and [to] direct the Secretary to act consistent with the court's findings immediately."

*398 **738 Although Harriman-Stites asked the trial court to consider this contempt motion at the October 22 hearing, the trial court, Sheridan, J. , rescheduled arguments on that motion and all other posttrial motions for October 29, 2018, because Judge Peck was unavailable until that date. Subsequently, because the October 29 hearing would have been after the statutory deadline for filing sample ballots; see General Statutes § 9-256 ; the trial court, Sheridan, J. , granted Harriman-Stites' request to mark off the October 29 hearing. Accordingly, the trial court has not taken action with respect to any of these posttrial motions filed by the endorsed candidates or Harriman-Stites.

In the meantime, briefing and oral argument on this writ of error and the plaintiffs' appeal continued on an expedited basis. See footnote 8 of this opinion. Beyond challenging the merits of the trial court's decision in the underlying action, the endorsed candidates now suggest that this writ of error has been rendered moot by intervening events, namely, the Secretary's September 11, 2018 decision to accept the Danbury faction's twelve unchallenged endorsements, as reflected in the list of nominees that she dated September 25, 2018. 10 In response, Harriman-Stites contends, inter alia, that (1) the writ of error is not moot, and (2) we should **739 direct judgment enforcing the trial court's order and requiring the Secretary to accept the Waterbury faction's endorsement for purposes of the ballots for the 2018 election in the 106th assembly district. 11

We heard oral argument on the writ of error and the underlying appeal on October 19, 2018. After oral arguments, we issued an order denying Harriman-Stites' request in this writ of error "for relief from [this] court prior to the election" 12 and stating that we would issue written opinions in both proceedings "in due course." This is the opinion relating to the writ of error.

We first consider whether this writ of error is moot, as argued by the endorsed candidates. "It is well established that [m]ootness implicates [this] court's subject matter jurisdiction and is thus a threshold matter for us to resolve....

*399 [T]he 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 through-out 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." (Internal quotation marks omitted.) In re Emma F. , 315 Conn. 414 , 423-24, 107 A.3d 947 (2015) ; see, e.g., Statewide Grievance Committee v. Burton , 282 Conn. 1 , 13, 917 A.2d 966 (2007) ("the central question **740 in a mootness problem is whether a change in the circumstances that prevailed at the beginning of the litigation has forestalled the prospect for meaningful, practical, or effective relief").

We conclude that the endorsed candidates' writ of error is moot. Given the Secretary's unchallenged decision to accept twelve of the thirteen nominations and print their names on the ballot for the 2018 election, there is no practical relief that we can afford them with respect to the trial court's decision. Accordingly, their claims are moot, and their writ of error is, therefore, nonjusticiable. See, e.g., Statewide Grievance Committee v. Burton , supra, 282 Conn. at 7 , 917 A.2d 966 ("[J]usticiability comprises several related doctrines, namely, standing, ripeness, mootness and the political question doctrine.... Consequently, a court may have subject matter jurisdiction over certain types of controversies in general, but may not have jurisdiction in any given case because the issue is not justiciable." [Citations omitted; internal quotation marks omitted.] ).

Harriman-Stites argues, however, that the writ of error is not moot with respect to her claims because of the Secretary's "confounding and inexplicable" decision to leave her off the ballot, despite the Secretary's assurance that she would abide by the trial court's decision in this case. Specifically, Harriman-Stites asked us to render judgment denying the writ of error and to direct the trial court to order the Secretary to comply with the trial court's order by putting her name on the ballot for the 106th assembly district. In responding to that argument, the endorsed candidates relied on, inter alia, River Dock & Pile, Inc. v. O & G Industries, Inc. , 219 Conn. 787 , 595 A.2d 839 (1991), and East Windsor v. East Windsor Housing, Ltd., LLC , 150 Conn. App. 268 , 92 A.3d 955 (2014), contending that we should refuse to reach this claim because "Harriman-Stites' raising of a claim for relief through an opposition to a writ of error is malapropos," and that her briefing of **741 this issue is founded on Telesca's "untested, testimonial affidavit [which is] replete with hearsay." (Emphasis in original.) Given the numerous factual issues attendant to Harriman-Stites' improperly raised claims for relief, we decline to consider them in the first instance in connection with this writ of error.

"A writ of error ... is generally subject to the same procedural rules as direct appeals." State v. Abushaqra , 153 Conn. App. 282 , 286 n.8, 100 A.3d 1014 , cert. denied, 315 Conn. 906 , 104 A.3d 757 (2014) ; see also Practice Book § 72-4 ("[e]xcept as otherwise provided by statute or rule, the prosecution and defense of a writ of error shall be in accordance with the rules for appeals"). Given Harriman-Stites' course of seeking this relief in her brief without filing a separate writ of error to seek affirmative relief with respect to the action or inaction of the trial court, we *400 take guidance from the ample body of case law considering claims raised by appellees in briefs, without having first been raised in a cross appeal, seeking relief vis-à-vis the judgment of the trial court. As a general rule, "[i]f an appellee wishes to change the judgment in any way, the party must file a cross appeal." (Internal quotation marks omitted.) East Windsor v. East Windsor Housing, Ltd., LLC , supra, 150 Conn. App. at 270 n.1, 92 A.3d 955 ; see also River Dock & Pile, Inc. v. O & G Industries, Inc. , supra, 219 Conn. at 792 n.5, 595 A.2d 839 (declining to reach affirmative claims for relief raised by appellee because appellee failed to file cross appeal); Board of Police Commissioners v. White , 171 Conn. 553 , 557, 370 A.2d 1070 (1976) (declining to reach appellees' claims that "the plaintiffs had waived any claim of illegality as to the collective bargaining agreement and that the court erred in overruling their plea in abatement addressed to the capacity of the plaintiffs to bring [the] action," because "[t]hey did not file an assignment of errors and a cross appeal and we do not consider the merits of these contentions"); **742 Farmers & Mechanics Savings Bank v. First Federal Savings & Loan Assn. , 167 Conn. 294 , 303 n.4, 355 A.2d 260 (1974) (declining to consider briefed issue concerning validity of restrictive covenants because, although appellees "raised this issue at the trial level, the trial court did not find it necessary to rule thereon," and appellee did not "file a cross appeal assigning error in the court's failure to treat this issue"); East Windsor v. East Windsor Housing, Ltd., LLC , supra, at 270 n.1, 92 A.3d 955 (refusing appellee's request "to direct the trial court to remove costs of seven title searches and seven filing fees from the fees awarded to the plaintiff" because of failure to file cross appeal). This rule is not, however, absolute, and the court may consider such a claim otherwise improperly raised in the appellee's brief in the absence of prejudice to the appellant. See Akin v. Norwalk , 163 Conn. 68 , 70-71, 301 A.2d 258 (1972) ; Rizzo v. Price , 162 Conn. 504 , 512-13, 294 A.2d 541 (1972) ; DiSesa v. Hickey , 160 Conn. 250 , 262-63, 278 A.2d 785 (1971).

We decline to reach this claim for affirmative relief, raised in the first instance in Harriman-Stites' brief. We agree with the endorsed candidates that this claim raises numerous issues of fact, particularly with respect to the feasibility of an order to put Harriman-Stites on the ballot given the timing of the election, that would have been more properly considered by a trial judge in the first instance. See Rizzo v. Price , supra, 162 Conn. at 513 , 294 A.2d 541 (declining to review appellee's challenge, raised for first time in brief, to trial court's failure to make certain factual conclusions as "clearly prejudicial to the appellant"); see also Furs v. Superior Court , 298 Conn. 404 , 412-13, 3 A.3d 912 (2010) (declining to reach state's claim in writ of error challenging contempt finding, which state did not raise as "an [alternative] ground for affirmance in a filing pursuant to Practice Book § 63-4 [a] [1], and did not designate ... as such in its brief" because it depended on presumption that "trial court would have accepted the state's claim of an independent **743 source of authority to grant use immunity only" or that plaintiff-in-error, "who claims that he refused to testify on the advice of counsel, would have refused to testify if he had been informed that the state had inherent authority to offer use immunity, which would be sufficient under the fifth amendment to compel his testimony and that this would not be violative of the statute" [footnote omitted] ); Gianetti v. Norwalk Hospital , 266 Conn. 544 , 560, 833 A.2d 891 (2003) ("[o]rdinarily it is not the function of this court or the Appellate Court to make factual *401 findings, but rather to decide whether the decision of the trial court was clearly erroneous in light of the evidence ... in the whole record" [internal quotation marks omitted] ). Although we are sympathetic to the delays experienced by Harriman-Stites in obtaining a hearing before the trial court, we note that, beyond objecting to the caseflow requests filed by the plaintiffs and the endorsed candidates, she did not file any motions before that court seeking expedited review, including assignment to a different judge given Judge Peck's unavailability, or seek similar relief from this court under Practice Book § 60-2. Accordingly, we conclude that this unmeritorious request for relief does not save the writ of error from dismissal. 13

The writ of error is dismissed.

In this opinion the other justices concurred.
