ROBINSON, J.

**729The defendant, Stephen J. Leonetti, appeals from the judgment of the trial court, rendered after a jury trial, in favor of the plaintiff, MacDermid, Inc., on its *617claim of unjust enrichment.1 On appeal, the defendant contends the following: (1) the plaintiff's unjust enrichment claim is barred by collateral estoppel on the basis of the proceedings underlying our decision in Leonetti v. MacDermid, Inc. , 310 Conn. 195, 76 A.3d 168 (2013) ; (2) the plaintiff's recovery is precluded by General Statutes §§ 31-2902 and 31-296 (a),3 the terms **730of a termination agreement (agreement) between the parties, and public policy; (3) the trial court's jury instructions were improper; and (4) the trial court improperly excluded certain evidence. The plaintiff disagrees and claims that many of the defendant's arguments are unpreserved, inadequately briefed, or both. We agree with the plaintiff. Accordingly, we affirm the judgment of the trial court.

The record, including our decision in Leonetti v. MacDermid, Inc. , supra, 310 Conn. at 195, 76 A.3d 168, reveals the following facts and procedural history. "The [defendant] worked for the [plaintiff] for twenty-eight years until he was discharged in early November, 2009. Five years earlier, in June, 2004, the [defendant] sustained a lower back injury during the course of his employment. The [defendant] timely filed notice of a workers' compensation claim related to this injury on April 14, 2005. The parties stipulated to the [Workers' Compensation Commissioner (commissioner) ] that the injury suffered by the [defendant] was a compensable injury.

"At the time that the [plaintiff] informed the [defendant] that he would be discharged from his employment, the [plaintiff] presented the [defendant] with a proposed ... agreement." Id., at 199, 76 A.3d 168. Under the terms of the agreement, the defendant's purpose in entering into the agreement was to provide "a binding agreement and understanding" with the plaintiff. As such, the agreement provided that the parties desired "to make the proposed transition as amiable and [trouble *618free] **731as possible ...." "Article II of the agreement signed by the parties provides that the [defendant] agreed to release the [plaintiff] from the following: 'any and all suits, claims, costs, demands, attorney's fees, damages, back pay, front pay, interest, special damages, general damages, workers' compensation claims, punitive damages, liabilities, actions, administrative proceedings, expenses, accidents, injuries and any other cause of action in law or equity that [the defendant] has or may have or might in any manner acquire which arise out of, relate to, or is in connection with his ... employment with, relationship with or business dealings with [the plaintiff] or the termination of that employment, relationship or dealings, or any other act, occurrence or omission, known or unknown, which occurred or failed to occur on or before the date this [a]greement is executed.'

"Article III of the agreement provides that, in consideration 'for the agreements and covenants made herein, the release given, the actions taken or contemplated to be taken, or to be refrained from,' the [defendant] would be paid twenty-seven weeks 'severance pay, determined solely upon the [defendant's] current base salary,' which amounted to $70,228.51, within thirty days of the [plaintiff's] receipt of the properly executed agreement; the [defendant] would continue to earn paid time off through his final day of employment; the [defendant] would be able to continue to obtain medical and dental benefits for up to eighteen consecutive months from his last date of employment under the Consolidated Omnibus Budget Reconciliation Act of 1985; 29 U.S.C. §§ 1161 through 1168 [2006] ; and the [defendant] had the option to convert group life insurance to individual life insurance within thirty days of his last day of employment.

"Article III of the agreement also provided that '[the defendant] understands that the payments and benefits **732listed above are all that [the defendant] is entitled to receive from [the plaintiff].... [The defendant] agrees that the payments and benefits above are more than [the plaintiff] is required to pay under its normal policies, procedures and plans.' ...

"Article IV of the agreement also required the [defendant] to enter into a one year noncompete agreement and also contained a clause stating in part that '[the defendant] acknowledges that he has been given a reasonable period of time of at least thirty ... days to review and consider this [a]greement before signing it. [The defendant] is encouraged to consult his or her attorney prior to signing this [a]greement.' " (Emphasis in original.) Leonetti v. MacDermid, Inc. , supra, 310 Conn. at 199-201, 76 A.3d 168.

Article V (b) of the agreement, entitled "[i]nvalid [c]lauses," provides: "It is understood and agreed that if any terms or provisions of this [a]greement shall contravene or be invalid under the laws of the United States, such contravention or invalidity shall not invalidate the whole [a]greement, but it shall be construed and enforced as to most nearly give effect to the intentions of the parties as expressed herein as possible."

"The [defendant] did not want to release his preexisting workers' compensation claim relating to the 2004 injury by signing the agreement. He consulted with his attorney, who contacted the [plaintiff's] counsel and requested that the [plaintiff] remove from the agreement the language that could operate to release the [defendant's] workers' compensation claim. The [plaintiff] refused to modify the language of the agreement. The [defendant's] counsel wrote a letter to the [plaintiff's] counsel asserting that the release language of article *619II of the agreement 'really has no effect without the [c]ommissioner's approval' and scheduled an informal hearing before a workers' compensation commissioner **733for January 8, 2010. The [plaintiff's] counsel did not attend the informal hearing, although a representative of Liberty Mutual Insurance Group, which administered the claim on behalf of the [plaintiff], did attend. Nothing was resolved on January 8, and, on January 27, 2010, the hearing was rescheduled for March 1, 2010.

"On January 26, 2010, the [plaintiff] sent the [defendant] a letter stating that, unless the [defendant] signed the unmodified agreement within the next ten days, it would withdraw its offer of $70,228.51 in severance pay. The [defendant] signed the agreement on February 2, 2010, and the commissioner found that the [defendant] did so because he did not wish to forfeit his severance pay. After the [plaintiff] received the signed agreement from the [defendant], it paid the [defendant] the $70,228.51. At that time, the commissioner had not approved the agreement as a 'voluntary agreement' or stipulation as defined in § 31-296.

"A formal hearing was held several months later to determine the enforceability of the language in article II of the agreement that dealt with the release of the [defendant's] workers' compensation claim. Specifically, the parties asked the commissioner to determine as follows: (1) '[w]hether a signed termination agreement between [an] employer and [an] employee can effectively waive the parties' rights and obligations set forth in the [Workers' Compensation Act (act), General Statutes § 31-275 et seq., in the absence of] approval of the agreement by a [commissioner]'; and (2) '[i]f the ... agreement does not waive the parties' rights and obligations set forth in the [act]-whether the [c]ommissioner would issue an order that the ... agreement be entered as a full and final stipulation of the [defendant's] workers' compensation claim against the [plaintiff].'

"The commissioner first found that, without approval by a commissioner, the agreement did not effectively **734waive the parties' rights and obligations under the act. Next, the commissioner found that the agreement should not be approved as a full and final stipulation of the [defendant's] workers' compensation claim. In making this determination, the commissioner credited the [defendant's] testimony that 'the [agreement] and payment of $70,228.51 was based on the number of years [the defendant] worked for the [plaintiff] and there was no money paid in this agreement for [the defendant's] workers' compensation claim.' As a result, the commissioner found that the [plaintiff] had paid no consideration to the [defendant] for his accepted workers' compensation claim. In light of these findings, the commissioner found that the Workers' Compensation Commission (commission) retained jurisdiction over the [defendant's] 2004 injury and scheduled a further hearing on the [defendant's] assertion that the injury has rendered a 10 percent permanent partial disability rating to the [defendant's] lumbar spine." Leonetti v. MacDermid, Inc. , supra, 310 Conn. at 201-203, 76 A.3d 168. The plaintiff appealed from the commissioner's decision to the Workers' Compensation Review Board (board), which affirmed the commissioner's decision. Id., at 203, 76 A.3d 168. Thereafter, the plaintiff appealed from the decision of the board. Id., at 199, 76 A.3d 168. We then transferred that appeal to this court. Id.

On appeal, this court concluded that, under § 31-296, a contractual release of a workers' compensation claim is unenforceable until it has been approved by the commissioner. Id., at 207, 76 A.3d 168. We *620then upheld the board's decision affirming the commissioner's refusal to approve the release as a full and final settlement of the defendant's workers' compensation claim in light of its finding that the defendant had not intended to release his compensation claim by signing the agreement. Id., at 208, 76 A.3d 168. Importantly, we went on to explain that the commission "is not competent to rule on the rights and obligations of **735the parties to a contract when those rights and obligations do not involve the issues that the legislature has authorized the commission to consider." Id., at 220, 76 A.3d 168. Thus, we noted that "[t]he enforceability of the remainder of the agreement is not a question for the workers' compensation forum.... Of course , [the plaintiff ] retains the right to seek whatever civil recourses it deems appropriate with respect to the remainder of the agreement, a matter about which we express no opinion ." (Emphasis added.) Id., at 221, 76 A.3d 168.

On November 30, 2011, while the workers' compensation matter was still pending on appeal, the plaintiff commenced the present action against the defendant, asserting claims of civil theft, fraud, unjust enrichment, conversion, and seeking rescission of the agreement.4 Specifically, the plaintiff claimed that its promise to pay the defendant under the agreement was rendered unenforceable by the defendant's conduct, false promises, and misrepresentations. The defendant denied the plaintiff's allegations and asserted certain special defenses, including res judicata or collateral estoppel, on the basis of the proceedings underlying this court's decision in Leonetti v. MacDermid, Inc. , supra, 310 Conn. at 195, 76 A.3d 168. The defendant also claimed that enforcement of the worker's compensation release provisions in the agreement would render the contract illegal under §§ 31-290 and 31-296.5 The plaintiff denied the special defenses.

**736The matter was tried to a jury, and, after the close of the plaintiff's evidence, the defendant moved for a directed verdict. The trial court reserved decision on that motion. Both parties filed preliminary requests to charge the jury, which were later supplemented. See part III of this opinion. Thereafter, the defendant took exception to the trial court's jury charge, claiming various errors in the charge given as well as the trial court's failure to instruct the jury in accordance with the defendant's request to charge.

On February 26, 2016, the jury returned a verdict in favor of the plaintiff on the *621claim of unjust enrichment, awarding $70,228.51 in damages, and in favor of the defendant on the remaining counts of the complaint. Thereafter, on March 7, 2016, the defendant filed a motion for judgment notwithstanding the verdict and a motion to set aside the verdict as to unjust enrichment. The trial court denied the defendant's motions in a memorandum of decision dated April 22, 2016, and rendered judgment in accordance with the jury's verdict. The trial court also awarded the plaintiff interest in accordance with a previous offer of compromise in the amount of $24,689.65 and attorney's fees of $350. This appeal followed. See footnote 1 of this opinion. Additional relevant facts will be set forth as necessary.

On appeal, the defendant contends that (1) the plaintiff's unjust enrichment claim is barred by collateral estoppel on the basis of the proceedings underlying this court's decision in **737Leonetti v. MacDermid, Inc. , supra, 310 Conn. at 195, 76 A.3d 168, (2) the plaintiff's recovery is precluded by §§ 31-290 and 31-296, the terms of the agreement, and public policy, (3) the trial court's jury instructions were improper, and (4) the trial court improperly excluded certain evidence. We address each of these claims in turn.

I

We first address the question of whether the plaintiff's unjust enrichment claim is barred by the doctrine of collateral estoppel.6 The defendant argues that the material facts underlying Leonetti v. MacDermid, Inc. , supra, 310 Conn. at 195, 76 A.3d 168, are the same as those at issue in the present case. Specifically, the defendant contends that it has already been finally determined that the agreement's workers' compensation release, upon which, the defendant argues, the plaintiff's claim is based, is unenforceable, and, therefore, his agreement to release his claim was not binding on him and cannot legally constitute a pretense or a promise. As such, the defendant further contends that Leonetti served as a final judicial determination that the agreement was neither enforceable nor effective with respect to the release of the defendant's workers' compensation claim. The defendant argues, therefore, that the principles **738of collateral estoppel barred the plaintiff from relitigating that same issue in the present case.

In response, the plaintiff argues, inter alia, that the defendant's collateral estoppel claim is meritless because he fails to identify any element of the plaintiff's unjust enrichment claim that was actually litigated and previously decided.7 The *622plaintiff also argues that the defendant's claim "stem[s] from the false premise that [the plaintiff's] unjust enrichment claim is an attempt to enforce the unenforceable workers' compensation release." We agree with the plaintiff and conclude that the doctrine of collateral estoppel does not bar the plaintiff's recovery for unjust enrichment.

We begin by setting forth the applicable standard of review. The defendant's claim requires us to determine whether the doctrine of collateral estoppel precludes **739the plaintiff's unjust enrichment claim. This presents a question of law over which our review is plenary. Lighthouse Landings, Inc. v. Connecticut Light & Power Co. , 300 Conn. 325, 345, 15 A.3d 601 (2011).

The fundamental principles underlying the doctrine of collateral estoppel are well established. "The common-law doctrine of collateral estoppel, or issue preclusion, embodies a judicial policy in favor of judicial economy, the stability of former judgments and finality.... Collateral estoppel, or issue preclusion, is that aspect of res judicata which prohibits the relitigation of an issue when that issue was actually litigated and necessarily determined in a prior action between the same parties upon a different claim.... For an issue to be subject to collateral estoppel, it must have been fully and fairly litigated in the first action. It also must have been actually decided and the decision must have been necessary to the judgment....

"An issue is actually litigated if it is properly raised in the pleadings or otherwise, submitted for determination, and in fact determined.... An issue is necessarily determined if, in the absence of a determination of the issue, the judgment could not have been validly rendered.... If an issue has been determined, but the judgment is not dependent [on] the determination of the issue, the parties may relitigate the issue in a subsequent action." (Citations omitted; emphasis in original; internal quotation marks omitted.) Lyon v. Jones , 291 Conn. 384, 406, 968 A.2d 416 (2009). "Before collateral estoppel applies [however] there must be an identity of issues between the prior and subsequent proceedings. To invoke collateral estoppel the issues sought to be litigated in the new proceeding must be identical to those considered in the prior proceeding." (Emphasis in original; internal quotation marks omitted.) Corcoran v. Dept. of Social Services , 271 Conn. 679, 689, 859 A.2d 533 (2004). In other words, *623"collateral estoppel has **740no application in the absence of an identical issue." Gladysz v. Planning & Zoning Commission , 256 Conn. 249, 261, 773 A.2d 300 (2001). Further, "an overlap in issues does not necessitate a finding of identity of issues for the purposes of collateral estoppel." Wiacek Farms, LLC v. Shelton , 132 Conn. App. 163, 172, 30 A.3d 27 (2011), cert. denied, 303 Conn. 918, 34 A.3d 394 (2012) ; see also Corcoran v. Dept. of Social Services , supra, at 691, 859 A.2d 533 (acknowledging that there was overlap of issues but declining to apply collateral estoppel because issues were not identical).

We conclude that there is not a sufficient identity of issues between the present case and Leonetti v. MacDermid, Inc. , supra, 310 Conn. at 195, 76 A.3d 168, to establish that the plaintiff's recovery is barred by collateral estoppel. A successful claim of unjust enrichment requires proof that (1) the defendant received a benefit, (2) the defendant did not perform in exchange for that benefit, and (3) the failure to perform operated to the detriment of the plaintiff. Gagne v. Vaccaro , 255 Conn. 390, 409, 766 A.2d 416 (2001). These issues were not considered in Leonetti . In Leonetti , this court identified the principal issue as "whether the [board] properly affirmed the commissioner's refusal to approve as a valid 'stipulation' [the agreement] between [the plaintiff] and [the defendant]." Leonetti v. MacDermid, Inc. , supra, at 198, 76 A.3d 168. We concluded that, under the act, the agreement's release of the defendant's workers' compensation claim was unenforceable "unless and until the commissioner approved the agreement." Id., at 207, 76 A.3d 168. In Leonetti , we noted that the commission's subject matter jurisdiction was limited to whether to approve the agreement as a release of the defendant's workers' compensation claim; as such, we explained that "[t]he enforceability of the remainder of the agreement is not a question for the workers' compensation forum ...."8 Id., at 221, 76 A.3d 168.

**741Thus, we concluded that any consideration of the defendant's "allegedly deceitful" conduct in entering into the agreement was properly left to another forum. Id., at 215-16, 76 A.3d 168. Specifically, we explained that, "once the commissioner determined that the $70,228.51 was not paid to the [defendant] in exchange for his release of his workers' compensation claim, the actions engaged in by the [defendant] warranted no further consideration in the workers' compensation forum." Id., at 220, 76 A.3d 168. Importantly, we noted that the plaintiff "retains the right to seek whatever civil recourses it deems appropriate with respect to the remainder of the agreement, a matter about which we express no opinion ." (Emphasis added.) Id., at 221, 76 A.3d 168. The plaintiff now seeks to have this "deceitful" conduct adjudicated in the context of the present unjust enrichment action, an issue that cannot be deemed barred by collateral estoppel given that Leonetti expressly did not address that issue.

The defendant, however, asserts that the plaintiff's claim of unjust enrichment is predicated on the defendant's "alleged[ly] deceptive conduct" and "[t]he only deceit that the [p]laintiff alleged was [the] [d]efendant's *624misrepresentation in the [a]greement that he would release his workers' compensation claim." We disagree. The plaintiff's claims do not depend on the enforceability of the release of workers' compensation claims contained in the agreement. It is undisputed that the defendant was allowed to pursue his workers' compensation claim and that the payment of $70,228.51 was not a workers' compensation benefit. Id., at 203, 76 A.3d 168. Rather, the plaintiff's unjust enrichment claim is based on the parties' actions as they relate to the remainder of the **742agreement. Specifically, the plaintiff points to several instances of the defendant's conduct, apart from the unenforceable release, that form the basis of its claim. For example, the plaintiff notes that the defendant acted contrary to the purpose of the agreement, which was "to make the proposed transition as amiable and trouble-free as possible ...." The plaintiff also notes that the defendant breached article IV (d) of the agreement, which provided that he had received a "reasonable period of time" to review the agreement prior to signing it, by arguing to the contrary before the commission. Most importantly, the plaintiff contends that the defendant breached article III of the agreement that provided that the defendant understood that "the payments ... are all that [the defendant] is entitled to receive from [the plaintiff].... [The defendant] agrees that the payments ... are more than [the plaintiff] is required to pay under its normal policies, procedures and plans."9 (Emphasis altered.) Accordingly, the prior proceedings in Leonetti did not resolve identical issues, and, as such, the plaintiff's recovery under its unjust enrichment claim is not barred by the doctrine of collateral estoppel.

II

We next turn to the defendant's claims that the plaintiff's recovery is barred by §§ 31-290 and 31-296, by the terms of the agreement, and by public policy and that, as such, the plaintiff cannot prevail on its unjust enrichment claim as a matter of law.

The record reveals the following additional facts and procedural history that are relevant to our resolution of these claims. On February 18, 2016, after the close **743of the plaintiff's evidence, the defendant filed a motion seeking a directed verdict. With respect to the plaintiff's unjust enrichment claim, this motion centered on the fact that the defendant had "received no consideration in exchange for the workers' compensation release." The defendant referenced his supplemental request to charge number forty-two, which stated that, "[b]ecause [the plaintiff] did not pay [the defendant] any consideration ... in exchange for releasing his workers' compensation claim, the workers' compensation release ... failed to comply with the requirements of Connecticut law ...." The trial court reserved decision on that motion. Thereafter, on March 7, 2016, the defendant filed a motion for judgment notwithstanding the verdict and a motion to set aside the verdict as to the claim of unjust enrichment. Both of those motions asserted that the plaintiff's recovery for unjust enrichment "would violate the public policy embodied in [the act], including but not limited to the provisions of [ §§ 31-290 and 31-296 ]." The trial court denied the defendant's motions on April 22, 2016. *625On appeal, the defendant claims that § 31-296 provides that a voluntary agreement between an employer and an injured employee must be reviewed by the commissioner to ascertain whether it conforms with the provisions of the act. Accordingly, the defendant claims that, because § 31-290 prohibits contracts from relieving employers of "any obligation created by [the act]," the plaintiff is improperly attempting to circumvent the approval requirement of § 31-296 by "couching its claim as one based upon unjust enrichment/implied contract ...." The defendant also argues that article V (b) of the agreement provides that, if the defendant's release of his workers' compensation claim was found to be invalid, the remainder of the agreement would still be enforced. According to the defendant, this, in turn, would bar the plaintiff from recovering under a theory **744of unjust enrichment, or a contract implied in law, because an express contract between the parties fore-closes the possibility of recovery under an implied-in-law contract. Finally, the defendant claims that the agreement violates public policy and is, therefore, unenforceable.10 In response, the plaintiff argues, inter alia, that the defendant did not adequately preserve these claims. We agree with the plaintiff and conclude that the defendant failed to adequately preserve these claims in his motion for a directed verdict.

Whether the evidence presented by the plaintiff is sufficient to withstand a motion for a directed verdict is a question of law, over which our review is plenary. Curran v. Kroll , 303 Conn. 845, 855, 37 A.3d 700 (2012). "Directed verdicts are not favored.... A trial court should direct a verdict only when a jury could not reasonably and legally have reached any other conclusion.... In reviewing the trial court's decision [to deny a defendant's motion for a directed verdict] we must consider the evidence in the light most favorable to the plaintiff.... A directed verdict is justified if ... the evidence is so weak that it would be proper for the court to set aside a verdict rendered for the other party." (Internal quotation marks omitted.) Bagley v. Adel Wiggins Group , 327 Conn. 89, 102, 171 A.3d 432 (2017) ; see also Gagne v. Vaccaro , supra, 255 Conn. at 400, 766 A.2d 416 (same standard applies to motions for judgment notwithstanding verdict).

A motion for a directed verdict serves to "adequately [alert the opposing party] and the trial court to the **745[relevant] legal issue[s] ...." Salaman v. Waterbury , 246 Conn. 298, 309, 717 A.2d 161 (1998). Specifically, "[a] motion for a directed verdict is a prerequisite to the filing of a motion to set aside the verdict.... [T]o permit the appellant first to raise posttrial an issue that arose during the course of the trial would circumvent the policy underlying the requirement of timely preservation of issues." (Citations omitted.) Willow Springs Condominium Assn., Inc. v. Seventh BRT Development Corp. , 245 Conn. 1, 49, 717 A.2d 77 (1998). "[A] motion for judgment notwithstanding the verdict is not a new motion, but the renewal of a motion for a directed verdict." (Internal quotation marks omitted.) *626Haynes v. Middletown , 314 Conn. 303, 312, 101 A.3d 249 (2014). Thus, such postverdict motions may not be predicated on a ground not previously raised in a motion for a directed verdict. Salaman v. Waterbury , supra, at 309, 717 A.2d 161 ; see also Practice Book § 16-37 ("a party who has moved for a directed verdict may move to have the verdict and any judgment rendered thereon set aside and have judgment rendered in accordance with his or her motion for a directed verdict " [emphasis added] ).

In the present case, the defendant's motion for directed verdict, as to the unjust enrichment claim, was based solely on the ground that the defendant "received no consideration in exchange for the [w]orkers' [c]ompensation release." Although the defendant's motion for a directed verdict referenced his supplemental request to charge forty-two, which in turn mentions the requirements of Connecticut law generally , there is no mention of § 31-290, § 31-296, article V (b) of the agreement, or public policy. Moreover, the defendant also made no mention whatsoever of article V (b) of the agreement in his postverdict motions. The defendant did, however, assert that the plaintiff's recovery "would violate the public policy embedded in [ §§ 31-290 and 31-296 ]" in his motion for judgment notwithstanding **746the verdict and motion to set aside the verdict. The defendant's attempt to preserve these statutory and public policy arguments by including them in his postverdict motions is unsuccessful because such motions may not be predicated on a ground not previously raised in a motion for a directed verdict.11 See Salaman v. Waterbury , supra, 246 Conn. at 309, 717 A.2d 161. Thus, the defendant did not timely alert the plaintiff and the trial court to his public policy and statutory arguments and never alerted the trial court to his argument regarding article V (b) of the agreement. Accordingly, we conclude that defendant did not adequately preserve these claims for appeal.12

III

We next address the defendant's challenges to the trial court's jury instructions. The record reveals the following additional relevant facts and procedural history.

**747The defendant filed a preliminary request to charge on November 6, 2015. Request thirty-six in that document sought an instruction *627relating to the provisions of §§ 31-290 and 31-296. Thereafter, on February 16, 2016, the defendant filed a supplemental request to charge. Request forty-four in that document pertained to this court's holding in Leonetti . Specifically, it sought the following instruction: "In considering the claims raised by [the plaintiff] concerning its severance agreement, [the plaintiff] is free to seek recourse with respect to the provisions contained in its agreement, other than the workers' compensation release. In other words, you may consider [the plaintiff's] claims of fraud, theft, conversion and unjust enrichment only as they pertain to the remainder of the severance agreement." The trial court declined to provide the jury with those specific instructions.

On appeal, the defendant contends that the trial court improperly failed to instruct the jury in accordance with requests forty-four and thirty-six and that the court's unjust enrichment charge was not proper. Specifically, the defendant claims that, in refusing to charge the jury in accordance with request forty-four, the plaintiff was able to "pursue its claim of unjust enrichment based on the very clause that had previously been judged unenforceable under the act." With respect to request thirty-six, the defendant claims that, in failing to charge the jury on the provisions of §§ 31-290 and 31-296, the trial court "permitted the jury to rely upon the unenforceable promise contained in the [a]greement in order to find the defendant liable in derogation of the public policy" of the act. The defendant also contends that the trial court's instructions on unjust enrichment improperly permitted the jury to find in favor of the plaintiff in the absence of proof that any of the defendant's actions or omissions caused the plaintiff injury.

**748In response, the plaintiff argues, inter alia, that the defendant failed to adequately brief the harmfulness of the alleged instructional errors. The plaintiff further argues that the trial court adequately instructed the jury on the legal principles of Leonetti and the provisions of §§ 31-290 and 31-296, and, as such, was under no obligation to charge the jury in the specific manner requested by the defendant. With respect to the trial court's instruction on unjust enrichment, the plaintiff argues, inter alia, that the defendant's claim is barred by the general verdict rule. We agree with the plaintiff and conclude that, with respect to requests forty-four and thirty-six, the defendant failed to adequately brief the harmfulness of the alleged instructional errors. We also conclude that the defendant's argument with respect to the trial court's unjust enrichment instructions is barred by the general verdict rule.

A

Requests Forty-Four and Thirty-Six

We begin our analysis of the defendant's claims with respect to requests forty-four and thirty-six by noting that "[w]e are not required to review issues that have been improperly presented to this court through an inadequate brief.... Analysis, rather than mere abstract assertion, is required in order to avoid abandoning an issue by failure to brief the issue properly.... Where a claim is asserted in the statement of issues but thereafter receives only cursory attention in the brief without substantive discussion or citation of authorities, it is deemed to be abandoned." (Internal quotation marks omitted.) Connecticut Light & Power Co. v. Gilmore , 289 Conn. 88, 124, 956 A.2d 1145 (2008). Moreover, without adequate briefing on the harmfulness of an alleged error, "the defendant is not entitled to review of [the] claim on the merits."

*628**749Saint Bernard School of Montville, Inc. v. Bank of America , 312 Conn. 811, 829, 95 A.3d 1063 (2014). Specifically, with respect to jury instructions, we have explained that "[i]t is axiomatic ... that not every error is harmful.... [W]e have often stated that before a party is entitled to a new trial ... he or she has the burden of demonstrating that the error was harmful.... An instructional impropriety is harmful if it is likely that it affected the verdict." (Citation omitted; internal quotation marks omitted.) Scanlon v. Connecticut Light & Power Co. , 258 Conn. 436, 448, 782 A.2d 87 (2001).

As the party challenging the jury instructions, the defendant was required to prove that the instructions likely affected the verdict. With respect to request forty-four, the defendant's harm analysis consists of only one sentence in which he claims that, had the trial court given his requested instruction, he "would have been entitled to judgment as a matter of law on the [f]ourth [c]ount of the amended complaint ...." As to request thirty-six, the defendant's harm analysis is similarly brief and asserts that the trial court's charge permitted the plaintiff to recover "in derogation of the protections afforded by the [a]ct" and misled the jury and caused injustice to him. Thus, the defendant's harm analyses consist of only cursory statements. In the absence of additional detail regarding the question of harm, we conclude that these claims of instructional error were inadequately briefed.13

Unjust Enrichment Jury Instruction

Turning to the defendant's claim that the trial court improperly instructed the jury on the plaintiff's unjust enrichment cause of action, we note that "[u]nder the general verdict rule, if a jury renders a general verdict for one party, and [the party raising a claim of error on appeal did not request] interrogatories, an appellate court will presume that the jury found every issue in favor of the prevailing party." (Internal quotation marks omitted.) Tetreault v. Eslick , 271 Conn. 466, 471, 857 A.2d 888 (2004). As such, the general verdict rule precludes an appeal claiming instructional error when the jury could have decided the case on a ground not implicated by the challenged instruction. See *629Kalams v. Giacchetto , 268 Conn. 244, 251-52, 842 A.2d 1100 (2004) (declining to consider claim of instructional error under general verdict rule); see also Dowling v. Finley Associates, Inc. , 248 Conn. 364, 371, 727 A.2d 1245 (1999) (noting that "if any ground for the verdict is proper, the verdict must stand" and that "only if every ground is improper does the verdict fall" [internal quotation marks omitted] ). The purpose of the rule is based "on the policy of the conservation of judicial resources, at both the appellate and trial levels. On the appellate level, the rule relieves an appellate court from the necessity of adjudicating claims of error that may not arise from **751the actual source of the jury verdict that is under appellate review.... In the trial court, the rule relieves the judicial system from the necessity of affording a second trial if the result of the first trial potentially did not depend upon the trial errors claimed by the appellant." (Internal quotation marks omitted.) Gajewski v. Pavelo , 229 Conn. 829, 836, 643 A.2d 1276 (1994).

"This court has held that the general verdict rule applies to the following five situations: (1) denial of separate counts of a complaint; (2) denial of separate defenses pleaded as such; (3) denial of separate legal theories of recovery or defense pleaded in one count or defense, as the case may be; (4) denial of a complaint and pleading of a special defense; and (5) denial of a specific defense, raised under a general denial, that had been asserted as the case was tried but that should have been specially pleaded." (Internal quotation marks omitted.) Kalams v. Giacchetto , supra, 268 Conn. at 255, 842 A.2d 1100.

In the present case, the defendant claims that the following unjust enrichment instruction by the trial court was improper: "When considering [the defendant's promise to release his workers' compensation claim] I instruct you, as a matter of law, that a promise includes within it a promise to do all that is necessary to carry the promise into effect." The third general verdict situation-separate legal theories of recovery pleaded in one count-is implicated in the present case, barring review of this claim. See Kalams v. Giacchetto , supra, 268 Conn. at 255, 842 A.2d 1100. The plaintiff's unjust enrichment claim not only relied on the defendant's intentions not to release his workers' compensation claim and to do all that was necessary to carry that into effect, but also on other misrepresentations contained in the agreement, such as the statements indicating the defendant believed that he had sufficient time to review the agreement and that $70,228.51 was more than he was **752entitled to receive.14 See Brown v. Bridgeport Police Dept. , 155 Conn. App. 61, 70, 107 A.3d 1013 (2015) (third situation was implicated because pleading "set forth distinct legal theories on which the jury could find [that] use of deadly force was statutorily authorized"); Thames River Recycling, Inc. v. Gallo , 50 Conn. App. 767, 782, 720 A.2d 242 (1998) (given that plaintiff had several theories of recovery supporting one count, case fell into third situation); cf. Staudinger v. Barrett , 208 Conn. 94, 99-100, 544 A.2d 164 (1988) (general verdict rule applied when "defendants' denial of negligence and their allegations of contributory negligence constitute[d] two discrete defenses, either of which could have supported the jury's general verdict"). The defendant did not request jury interrogatories that would properly establish *630the ground on which the jury made its decision on the unjust enrichment count. As such, the defendant's claim of instructional error as to unjust enrichment is unreviewable under the general verdict rule.

IV

Finally, we address the defendant's evidentiary claims. The following additional facts are relevant to our resolution of these claims. In accordance with the court's trial management orders, the plaintiff moved to exclude, inter alia, all evidence and argument showing that the commissioner had imposed a $500 fine on the plaintiff as a result of its general counsel's refusal to attend a workers' compensation hearing, including exhibit I, which is the January 8, 2010 order from the commission imposing that fine. The defendant objected **753to that motion and also opposed the plaintiff's objections to the introduction of defendant's exhibits C, D, and F through L, which were based on similar legal arguments.15 The plaintiff also sought to exclude exhibit Z, which was an April 5, 2010 letter from the defendant's attorney. The defendant opposed that motion. After oral argument, the trial court issued a ruling excluding exhibit I and ruling that it would consider other evidentiary issues briefed in the motion during trial. The trial court ultimately excluded defendant's exhibits G, H, I, J, Z, and JJJ16 on the basis of hearsay, the danger of unfair prejudice substantially outweighing probative value, and confusion of the issues.

On appeal, the defendant claims that the trial court improperly excluded his exhibits G, H, I, J, Z, and JJJ. The defendant contends that these exhibits revealed relevant communications between the parties and the state of mind of the defendant. Moreover, the defendant contends that, contrary to the plaintiff's objection at trial, exhibits G, H, I, J, Z, and JJJ did not constitute hearsay. Specifically, the defendant contends that exhibits G, J, Z, and JJJ did not constitute hearsay because they were not offered for the truth of the matters **754asserted. In response, the plaintiff argues, inter alia, that the defendant's arguments with respect to exhibits G, H, I, J, and JJJ, are unreviewable because the defendant does not address all of the trial court's bases for excluding these exhibits. The plaintiff also argues that the defendant failed to adequately brief the harmfulness of the trial court's evidentiary rulings, and, as such, the defendant's claim with respect to exhibit Z may not be considered. We agree with the plaintiff, and conclude that, because the defendant did not challenge all of the bases under which the trial court excluded exhibits G, H, I, J, and JJJ, his claims on appeal related to those exhibits are moot. *631With respect to exhibit Z, we further conclude that the defendant failed to adequately brief the harmfulness of the evidentiary ruling.

A

Exhibits G, H, I, J, and JJJ

We begin our analysis of the defendant's claims with respect to exhibits G, H, I, J, and JJJ by noting that "[m]ootness is a question of justiciability that must be determined as a threshold matter because it implicates [this] court's subject matter jurisdiction ...." (Internal quotation marks omitted.) Lyon v. Jones , supra, 291 Conn. at 392, 968 A.2d 416. "The fundamental principles underpinning the mootness doctrine are well settled.... Because courts are established to resolve actual controversies, before a claimed controversy is entitled to a resolution on the merits it must be justiciable. Justiciability requires (1) that there be an actual controversy between or among the parties to the dispute ... (2) that the interests of the parties be adverse ... (3) that the matter in controversy be capable of being adjudicated by the judicial power ... and (4) that the determination of the controversy will result in practical relief to the complainant." (Citation omitted; internal quotation **755marks omitted.) State v. Lester , 324 Conn. 519, 526, 153 A.3d 647 (2017). "[I]t 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 .... In determining mootness, the dispositive question is whether a successful appeal would benefit the plaintiff or defendant in any way." (Citation omitted; emphasis in original; internal quotation marks omitted.) Lyon v. Jones , supra, at 394, 968 A.2d 416.

"Where an appellant fails to challenge all bases for a trial court's adverse ruling on his claim, even if this court were to agree with the appellant on the issues that he does raise, we still would not be able to provide [him] any relief in light of the binding adverse finding[s] [not raised] with respect to those claims.... Therefore, when an appellant challenges a trial court's adverse ruling, but does not challenge all independent bases for that ruling, the appeal is moot." (Citation omitted; internal quotation marks omitted.) State v. Lester , supra, 324 Conn. at 526-27, 153 A.3d 647 ; see also Lyon v. Jones , supra, 291 Conn. at 395, 968 A.2d 416 ("even if we were to agree with the plaintiff on the issue that she does raise with respect to her ... claims, we still would not be able to provide her any relief in light of the binding adverse finding with respect to those claims" [emphasis in original] ).

In the present case, the trial court excluded exhibits G, H, J, and JJJ as both hearsay and because their probative value was substantially outweighed by the danger of unfair prejudice. The trial court excluded exhibit I because its probative value was substantially outweighed by the danger of unfair prejudice and confusion of the issues. On appeal, the defendant challenges the trial court's exclusion of these exhibits only on the limited basis of hearsay. Because there are independent bases for the trial court's exclusion of the evidence that the defendant has not challenged in the present appeal, **756even if we were to hold that the trial court improperly excluded exhibits G, H, I, J, and JJJ on the basis of hearsay, we could grant no practical relief to the defendant. Accordingly, we conclude that the defendant's evidentiary claims pertaining to these exhibits are moot and that, therefore, this *632court lacks subject matter jurisdiction to consider those claims.17

B

Exhibit Z

Turing to the defendant's claim with respect to exhibit Z, we set forth the applicable standard of review. "Upon review of a trial court's decision, we will set aside an evidentiary ruling only when there has been a clear abuse of discretion.... The trial court has wide discretion in determining the relevancy of evidence ... and [e]very reasonable presumption should be made in favor of the correctness of the court's ruling in determining whether there has been an abuse of discretion." (Internal quotation marks omitted.) State v. Santos , 318 Conn. 412, 423, 121 A.3d 697 (2015). Moreover, "evidentiary rulings will be overturned on appeal only where there was an abuse of discretion and a showing by the defendant of substantial prejudice or injustice." (Internal quotation marks omitted.) Stokes v. Norwich Taxi, LLC , 289 Conn. 465, 489, 958 A.2d 1195 (2008).

"It is a fundamental rule of appellate review of evidentiary rulings that if [the] error is not of constitutional dimensions, an appellant has the burden of establishing **757that there has been an erroneous ruling which was probably harmful to him ." (Emphasis added; internal quotation marks omitted.) State v. Gonzalez , 272 Conn. 515, 527, 864 A.2d 847 (2005). Thus, "[w]e do not reach the merits of [a] claim [where] the defendant has not briefed how he was harmed by the allegedly improper evidentiary ruling." State v. Baker , 168 Conn. App. 19, 35, 145 A.3d 955, cert. denied, 323 Conn. 932, 150 A.3d 232 (2016) ; see also Saint Bernard School of Montville, Inc. v. Bank of America , supra, 312 Conn. at 829, 95 A.3d 1063 (without adequate briefing of harmfulness of error, "the defendant is not entitled to review of [the] claim on the merits").

The only mention of the harmfulness of this evidentiary ruling in the defendant's brief consists of only broad statements and a conclusory assertion that the alleged errors "deprived [the] defendant of his opportunity to properly and fairly present his case to the jury and misled the jury ...." Nowhere does the defendant's brief explain how the verdict was likely affected by the trial court's particular exclusion of exhibit Z. Accordingly, because we conclude that the defendant failed to adequately brief the harmfulness of the trial court's evidentiary ruling, he is not entitled to review of his claim with respect to exhibit Z on the merits.

The appeal is dismissed with respect to the defendant's claims regarding exhibits G, H, I, J, and JJJ; the judgment is affirmed.

In this opinion the other justices concurred.
