The narrow issue presented by this appeal is whether the statute of limitations of the state of Connecticut or the state of Delaware governs the unjust enrichment claims brought by the plaintiff, Reclaimant Corp., against the defendants, William J. Deutsch and Laurence B. Simon, seeking recovery for alleged overpayments issued to the defendants by the plaintiff's putative predecessor in interest pursuant to a limited partnership agreement. The trial court rendered summary judgment in favor of the defendants, concluding that the plaintiff's unjust enrichment claims were governed by Delaware law and were time-barred under the three-year statute of limitations in the Delaware Revised Uniform Limited Partnership Act (DRULPA), Del. Code Ann. tit. 6, § 17-607 (c) (2005). 1 On appeal, the plaintiff contends that summary judgment was improper because Connecticut law governs the timeliness of its unjust enrichment claims and that those claims timely were filed under Connecticut law.

We conclude that Delaware law governs the substantive rights and liabilities of the parties arising out of the limited partnership agreement but that Connecticut law governs matters of judicial administration and procedure. We further conclude that, because the plaintiff's unjust enrichment claims have a common-law origin, the limitation period properly is "characterized as procedural because it functions only as a qualification on the remedy to enforce the preexisting right." Baxter v. Sturm, Ruger & Co. , 230 Conn. 335 , 347, 644 A.2d 1297 (1994). Thus, Connecticut law, rather than Delaware law, controls the timeliness of the plaintiff's claims. We therefore reverse the judgment of the trial court and remand the case for further proceedings.

I

The record reveals the following relevant facts and procedural history. In 2007, the defendants entered into a limited partnership agreement with SV Special Situations Fund LP (SV Fund), a Delaware limited partnership formed for the purpose of investing in and trading securities and other investments. In early 2008, the defendants redeemed their respective investments and withdrew from the partnership as of March 31, 2008. Deutsch received approximately 90 percent of the funds in his capital account, for a total distribution in the amount of $22,309,473.03, and Simon received approximately 90 percent of the funds in his capital account, for a total distribution in the amount of $2,176,785.80. 2

By letters dated September 4, 2012, Scott A. Stagg, the director of SV Fund, informed each of the defendants that the "net asset value of your interest in the ... Fund was ... overstated [at the time you redeemed your investment], resulting in ... overpayment ...." Stagg alleged that Deutsch had received a total overpayment in the amount of $7,047,974.03 and that Simon had received a total overpayment in the amount of $724,557.80, and he demanded that the defendants return the alleged overpayments within thirty days.

The defendants responded by requesting documentation and clarification of the alleged overpayments. The defendants also requested payment of the remaining funds in their capital accounts, which had been held back at the time of redemption. Specifically, Deutsch asked for the payment of $807,127.97 and Simon asked for the payment of $102,753.

SV Fund was liquidated in February, 2013, and its claims against the defendants were assigned to the plaintiff. On May 8, 2013, the plaintiff filed a two-count complaint against the defendants, both of whom reside in Connecticut. In the first count, the plaintiff alleged that Deutsch had been "unjustly enriched as a result of receiving and retaining" the alleged overpayment in the amount of $7,047,974.03. In the second count, the plaintiff alleged that Simon had been "unjustly enriched as a result of receiving and retaining" the alleged overpayment in the amount of $724,557.80.

The defendants moved to strike the complaint as time-barred under the three-year statute of limitations in § 17-607 (c) of DRULPA because "the distributions were made in 2008 and the complaint was not filed until 2013 ...." The plaintiff opposed the defendants' motion to strike, contending that, "if any statute of limitations applies to the plaintiff's equitable unjust enrichment claims ... it is [Connecticut's] six-year statute [of limitations applicable to contracts] set forth in [General Statutes] § 52-576 (a), and the plaintiff's claims are, therefore, not time-barred." The trial court determined that it was "inappropriate to decide this potentially dispositive issue within the context of a motion to strike" and, therefore, denied the defendants' motion.

The defendants filed an answer denying that they had been unjustly enriched and raising the following affirmative defenses: (1) the plaintiff's claims are barred by § 17-607 (b) of DRULPA, "which specifies that a limited partner who unknowingly receives an alleged overpayment is not liable for returning the amount of that distribution"; (2) the plaintiff's claims are barred by the three-year statute of limitations in § 17-607 (c) of DRULPA; (3) the plaintiff's complaint fails to state a claim on which relief may be granted because SV Fund "could have prevented and/or addressed any potential alleged overpayments"; (4) the plaintiff's claims are barred by the three-year statute of limitations governing torts in General Statutes § 52-577 ; (5) the plaintiff "lacks standing because [it] has not established its right to bring a cause of action on behalf of SV Fund"; (6) the plaintiff "lacks standing because [it] has not established that SV Fund or its assignees have a right to bring a cause of action on behalf of 3V Capital Partners, LP"; 3 (7) the plaintiff's claims are barred by the doctrine of laches due to its "inexcusable delay" in filing suit; (8) the plaintiff's claims are "barred by the doctrine of waiver"; (9) the plaintiff's claims are "barred by the doctrine of estoppel"; (10) the plaintiff's claims "are barred by the equitable doctrine of unclean hands"; (11) the plaintiff's claims "are barred by the doctrine of satisfaction and accord"; and (12) the plaintiff "failed to mitigate its damages, if any exist." The defendants also filed a counterclaim against the plaintiff on the basis of SV Fund's alleged failure to distribute the funds remaining in their capital accounts.

The plaintiff moved for summary judgment on the defendants' second and fourth special defenses, contending that "Connecticut's statute of limitations law applies to the plaintiff's common-law unjust enrichment claims" and "Connecticut law provides that either no statute of limitations applies to an equitable action for unjust enrichment, or, at a minimum, that a six-year statute of limitations applies, and this action is timely under either measure." The defendants opposed the plaintiff's motion for summary judgment and moved for summary judgment on their first, second, third, fourth, and seventh special defenses. The essence of the defendants' argument was that the plaintiff's "contention that Connecticut law applies to [this] dispute is academic since neither Connecticut nor Delaware law ... permit[s] parties to pursue unjust enrichment claims as a means to rewrite the express terms of a written agreement governing the payments at issue" and the plaintiff's unjust enrichment claims are time-barred under both Delaware and Connecticut law.

The trial court's resolution of the parties' competing motions for summary judgment was guided largely by the fact that the limited partnership agreement contains a choice of law provision, which states: "This [a]greement and all rights and liabilities of the parties hereto shall be governed by and construed in accordance with the laws of the [s]tate of Delaware, without regard to its conflicts of law principles." The trial court observed that § 187 (1) of the Restatement (Second) of Conflict of Laws "requires that the law of the state chosen by the parties to govern their contractual rights and duties will be applied if the particular issue was one which the parties could have resolved by an explicit provision in their agreement directed to that issue." The trial court determined that the contractual choice of law provision here "expressly elects Delaware law for all issues regarding the parties' rights and liabilities including those set forth in [§] 17-607 (c) of ... DRULPA." In arriving at its decision, the trial court rejected the plaintiff's contention that the choice of law provision governed the substantive law of the contract but not procedural matters like the applicable statute of limitations, reasoning that the "broad and clear" language of the contract "evidences an intent to include all issues (whether substantive or procedural) concerning rights, and all issues concerning liabilities, to be governed by Delaware law within the breadth of the choice of law election." Having determined that "the parties clearly and unambiguously elected to have Delaware law govern their relationship, even when it provides time limits on liabilities that are different [from] the time limits on liabilities that may be imposed by the state of Connecticut," 4 the trial court granted the defendants' motion for summary judgment on their second special defense, denied the plaintiff's motion for summary judgment, and rendered judgment in favor of the defendants.

The plaintiff filed an appeal with the Appellate Court, and we transferred the appeal to this court pursuant to General Statutes § 51-199 (c) and Practice Book § 65-1. On appeal, the plaintiff claims that the trial court improperly rendered summary judgment in favor of the defendants because the choice of law provision in the limited partnership agreement "refers only to Delaware substantive law; it does not encompass Delaware procedural law," and the limitation period governing common-law claims properly is characterized as procedural rather than substantive. Alternatively, the plaintiff contends that, even if Delaware procedural law controls the timeliness of its claims, § 17-607 (c) of DRULPA is inapplicable because the defendants withdrew from the limited partnership in 2008 and, therefore, were not limited partners at the time the action was filed. Lastly, the plaintiff claims that its complaint was filed timely under Connecticut law because "unjust enrichment is either not subject to any statute of limitations at all (as an equitable claim) or is governed by the six-year [limitation] period [applicable to contracts] set forth in ... § 52-576 (a)." The defendants respond that the judgment of the trial court should be affirmed because that court properly concluded that the limited partnership agreement expressly incorporated Delaware law, including the three-year limitation period in § 17-607 (c) of DRULPA. They also argue that Connecticut law requires the application of § 17-607 (c) because General Statutes § 34-38f (1) provides that "the laws of the state under which a foreign limited partnership is organized govern its organization and internal affairs and the liability of its limited partners." Alternatively, the defendants contend that, even if we were to conclude that Connecticut law, rather than Delaware law, governs the timeliness of the plaintiff's claims, the trial court's judgment nonetheless should be affirmed on the ground that the plaintiff's unjust enrichment claims are time-barred under either the three-year statute of limitations in § 52-577 or the doctrine of laches. Lastly, the defendants argue that the judgment of the trial court may be affirmed on the alternative ground that "the equitable remedy of unjust enrichment is unavailable where there is a written contract between the parties on the subject."

The applicable standard of review is not in dispute. " Practice Book § 17-49 provides that summary judgment shall be rendered forthwith if the pleadings, affidavits and any other proof submitted show that there is no genuine issue as to any material fact and that the moving party is entitled to judgment as a matter of law. In deciding a motion for summary judgment, the trial court must view the evidence in the light most favorable to the nonmoving party.... The party moving for summary judgment has the burden of showing the absence of any genuine issue of material fact and that the party is, therefore, entitled to judgment as a matter of law.... On appeal, we must determine whether the legal conclusions reached by the trial court are legally and logically correct and whether they find support in the facts set out in the memorandum of decision of the trial court.... Our review of the trial court's decision to grant the defendant's motion for summary judgment is plenary." (Citations omitted; internal quotation marks omitted.) Cogan v. Chase Manhattan Auto Financial Corp. , 276 Conn. 1 , 6-7, 882 A.2d 597 (2005). It is well settled that "[c]hoice of law questions are subject to de novo review." Western Dermatology Consultants, P.C. v. VitalWorks, Inc. , 322 Conn. 541 , 558, 153 A.3d 574 (2016) ; see also American States Ins. Co. v. Allstate Ins. Co. , 282 Conn. 454 , 461, 922 A.2d 1043 (2007) (noting that "choice of law issues present questions of law over which our review is plenary").

Nor do the parties disagree about the fundamental starting point of the conflict of laws analysis, which requires initial resort to Connecticut conflict of laws rules. "In determining the governing law, a forum applies its own [conflict of laws] rules ...." Gibson v. Fullin , 172 Conn. 407 , 411, 374 A.2d 1061 (1977). The applicable Connecticut conflict of laws rule depends upon the nature of the plaintiff's claim. See Macomber v. Travelers Property & Casualty Corp. , 277 Conn. 617 , 640, 894 A.2d 240 (2006) (applying different choice of law rules to tort and contract claims). This court previously has referred to unjust enrichment as both a tort 5 and a quasi-contractual claim; 6 however, we also have recognized, more accurately, that it is neither a species of tort nor contract but, rather, an equitable "means of recovery in restitution." Walpole Woodworkers, Inc. v. Manning , 307 Conn. 582 , 587 n.9, 57 A.3d 730 (2012) (clarifying that unjust enrichment is a "noncontractual means of recovery in restitution"); see also Vertex, Inc. v. Waterbury , 278 Conn. 557 , 573, 898 A.2d 178 (2006) ("[u]njust enrichment is, consistent with the principles of equity, a broad and flexible remedy," and there is "no other test than what, under a given set of circumstances, is just or unjust, equitable or inequitable, conscionable or unconscionable" [internal quotation marks omitted] ); Connecticut National Bank v. Chapman , 153 Conn. 393 , 399, 216 A.2d 814 (1966) (noting that unjust enrichment "is essentially equitable," and, in order to recover in restitution under that doctrine, there is no requirement that "the party unjustly enriched should have been guilty of any tortious or fraudulent act").

Section 221 of the Restatement (Second), titled "Restitution," "is concerned with what law governs a person's right to recover from another, on grounds of fairness and good conscience, the amount by which the other has been unjustly enriched at his expense." 1 Restatement (Second), Conflict of Laws c. 8, topic 6, introductory note, p. 726 (1971). Section 221 provides in relevant part that "[i]n actions for restitution, the rights and liabilities of the parties with respect to the particular issue are determined by the local law of the state which, with respect to that issue, has the most significant relationship to the occurrence and the parties under the principles stated in § 6." 7 Id., § 221 (1), p. 727. Under subsection (2) of § 221, one of the "[c]ontacts to be taken into account in applying the principles of § 6" is "the place where a relationship between the parties was centered, provided that the receipt of enrichment was substantially related to the relationship." Id., § 221 (2) (a), p. 727. According to the commentary, "[t]he place where a relationship between the parties was centered, provided that this relationship was substantially related to the receipt of enrichment, is the contact that, as to most issues, is given the greatest weight in determining the state of the applicable law." Id., comment (d), pp. 729-30. For example, "[w]hen the enrichment was received in the course of the performance of a contract between the parties, the law selected by application of the rules of §§ 187-188 [of the Restatement (Second) ] will presumably govern one party's rights in restitution against the other. The applicable law will be that chosen by the parties if they have made an effective choice under the circumstances stated in § 187." Id., comment (d), p. 730.

In the present case, the alleged unjust enrichment occurred in the course of the performance of the limited partnership agreement, and, therefore, we must turn to § 187 of the Restatement (Second) to resolve the conflict of law inquiry. Section 187 of the Restatement (Second) provides in relevant part that "[t]he law of the state chosen by the parties to govern their contractual rights and duties will be applied if the particular issue is one which the parties could have resolved by an explicit provision in their agreement directed to that issue." Id., § 187 (1), p. 561; see Elgar v. Elgar , 238 Conn. 839 , 850, 679 A.2d 937 (1996) (noting that, under § 187, "parties to a contract generally are allowed to select the law that will govern their contract"). This "is a rule providing for incorporation by reference and is not a rule of choice of law. The parties, generally speaking, have power to determine the terms of their contractual engagements. They may spell out these terms in the contract. In the alternative, they may incorporate into the contract by reference extrinsic material which may, among other things, be the provisions of some foreign law. In such instances, the forum will apply the applicable provisions of the law of the designated state in order to effectuate the intention of the parties." 1 Restatement (Second), supra, § 187, comment (c), p. 563.

The limited partnership agreement here contains a choice of law provision that provides: "This [a]greement and all rights and liabilities of the parties hereto shall be governed by and construed in accordance with the laws of the [s]tate of Delaware, without regard to its conflicts of law principles." Pursuant to this choice of law provision, as well as the other parts of the contract evidencing the signatories' intent "to form a limited partnership ... in accordance with the provisions of [DRULPA]," we conclude that Delaware substantive law controls the plaintiff's unjust enrichment claims. 8

This does not end our analysis, however, because it is well established that "in a choice of law situation the forum state will apply its own procedure ...." Paine Webber Jackson & Curtis, Inc. v. Winters , 22 Conn. App. 640 , 650, 579 A.2d 545 , cert. denied, 216 Conn. 820 , 581 A.2d 1055 (1990) ; see, e.g., Ferri v. Powell-Ferri , 326 Conn. 438 , 447, 165 A.3d 1137 (2017) ("[a]lthough the choice of law provision in the 1983 trust dictates that matters of substance will be analyzed according to Massachusetts law, procedural issues such as the standard of review [and standing] are governed by Connecticut law"); Montoya v. Montoya , 280 Conn. 605 , 612 n.7, 909 A.2d 947 (2006) ("[a]lthough the agreement's choice of law provision dictates that the substance of the contract will be analyzed according to New York law, procedural issues such as the applicable standard of review are governed by Connecticut law"); People's United Bank v. Kudej , 134 Conn. App. 432 , 438, 39 A.3d 1139 (2012) ("because the 1998 note and the guarantee contain choice of law clauses stating that they are to be governed and construed in accordance with Massachusetts law ... we are guided by Massachusetts substantive law in deciding the defendant's claims, but we must apply the procedural laws of Connecticut"). This approach is consistent with § 122 of the Restatement (Second), which provides that "[a] court usually applies its own local law rules prescribing how litigation shall be conducted even when it applies the local law rules of another state to resolve other issues in the case." 1 Restatement (Second), supra, § 122, p. 350. As the commentary to that section explains, "[t]he forum has compelling reasons for applying its own rules" to procedural issues, even if the substantive law of another jurisdiction applies, because, "in matters of judicial administration, it would often be disruptive or difficult for the forum to apply the local rules of another state. The difficulties involved in doing so would not be repaid by a furtherance of the values that the application of another state's local law is designed to promote." Id., comment (a), p. 350. Additionally, "[p]arties do not usually give thought to matters of judicial administration before they enter into legal transactions," and, therefore, "the parties have no expectations as to such eventualities, and there is no danger of unfairly disappointing their hopes by applying the forum's rules in such matters." Id., p. 351. Even if the application of the forum's procedural rule would alter the outcome of a case, "the forum will usually apply its own rule if the issue primarily concerns judicial administration. The statute of limitations is a striking example of such an issue ...." Id.

In Baxter v. Sturm, Ruger & Co. , supra, 230 Conn. at 339 , 644 A.2d 1297 , we addressed whether a "statute of limitation[s] is procedural or substantive for choice of law purposes." We noted that it is "undisputed that ... remedies and modes of procedure depend upon the lex fori" and that statutes of limitations typically are procedural because they "relate to the remedy as distinguished from the right." (Internal quotation marks omitted.) Id. ; see also Thomas Iron Co. v. Ensign-Bickford Co. , 131 Conn. 665 , 668, 42 A.2d 145 (1945) ("[i]t is undisputed that, as a principle of universal application, remedies and modes of procedure depend upon the lex fori"). Nonetheless, a statute of limitations may be deemed substantive, rather than procedural, "if the limitation is so interwoven with ... the cause of action as to become one of the congeries of elements necessary to establish the right ...." (Internal quotation marks omitted.) Baxter v. Sturm, Ruger & Co. , supra, at 340, 644 A.2d 1297 ; see also Thomas Iron Co. v. Ensign-Bickford Co. , supra, at 668-69, 42 A.2d 145 (observing that, if "the remedial law of the foreign jurisdiction is inseparable from the cause of action," then "the lex loci and not the lex fori governs"). We determined that neither statutes of limitations nor statutes of repose are "substantive [or] procedural per se for choice of law purposes," but, rather, the characterization of the applicable limitation period "depends on the nature of the underlying right that forms the basis of the lawsuit. If the right existed at common law, then the [limitation period] is properly characterized as procedural because it functions only as a qualification on the remedy to enforce the preexisting right. If, however, the right is newly created by the statute, then the [limitation period] is properly characterized as substantive because the period of repose is so integral a part of the cause of action as to warrant saying that it qualifie[s] the right." (Internal quotation marks omitted.) Baxter v. Sturm, Ruger & Co. , supra, at 346-47, 644 A.2d 1297 ; see also 1 Restatement (Second), supra, § 143, p. 400 ("[a]n action will not be entertained in another state if it is barred in the state of the otherwise applicable law by a statute of limitations which bars the right and not merely the remedy"). 9 Applying these principles to the facts at issue in Baxter , we held that the timeliness of the plaintiff's product liability claims was governed by Connecticut's statute of limitations, rather than Oregon's statute of repose, "in light of the [common-law] origin of the law of products liability ...." Baxter v. Sturm, Ruger & Co. , supra, at 347, 644 A.2d 1297 .

Pursuant to Baxter , the procedural or substantive nature of the limitation period depends on whether the plaintiff's right to relief existed under Delaware common law. See id., at 341, 644 A.2d 1297 (examining Oregon law to determine whether plaintiff's claims existed at common law). 10 Under Delaware law, unjust enrichment is a claim for restitution. See Fleer Corp. v. Topps Chewing Gum, Inc. , 539 A.2d 1060 , 1062 (Del. 1988). The right to relief is not created by statute but, rather, derives from equitable principles under the common law. See, e.g., Schock v. Nash , 732 A.2d 217 , 232 (Del. 1999) ("[u]njust enrichment is defined as the unjust retention of a benefit to the loss of another, or the retention of money or property of another against the fundamental principles of justice or equity and good conscience" [internal quotation marks omitted] ). Given the common-law origin of the plaintiff's unjust enrichment claims, we conclude that the limitation period "is properly characterized as procedural because it functions only as a qualification on the remedy to enforce the preexisting right." 11 Baxter v. Sturm, Ruger & Co. , supra, 230 Conn. at 347 , 644 A.2d 1297 . Accordingly, Connecticut law, rather than Delaware law, governs the timeliness of the plaintiff's claims.

The defendants contend that § 17-607 (c) of DRULPA is substantive, rather than procedural, because it extinguishes the liability of a limited partner after the expiration of three years. To support this contention, the defendants rely on Century City Doctors Hospital, LLC v. Friedman , 466 B.R. 1 , 12-13 (Bankr. C.D. Cal. 2012), and Freeman v. Williamson , 383 Ill.App.3d 933 , 322 Ill.Dec. 208 , 890 N.E.2d 1127 , 1133-34 (2008), both of which held that § 17-607 (c) is substantive because it is a statute of repose, not a statute of limitations. We agree with the courts in Century City Doctors Hospital, LLC , and Freeman that § 17-607 (c) properly is characterized as a statute of repose because it "clearly terminates the possibility of the limited partner's liability after a defined period of time, three years after receiving a distribution, regardless of whether a potential plaintiff knows of his or her cause of action." Century City Doctors Hospital, LLC v. Friedman , supra, at 13, quoting Freeman v. Williamson , supra, 322 Ill.Dec. 208 , 890 N.E.2d at 1134 ; see Baxter v. Sturm, Ruger & Co. , supra, 230 Conn. at 341 , 644 A.2d 1297 (recognizing that "statutes of repose differ in some respects from statutes of limitation" because they terminate "any right of action after a specific time has elapsed, regardless of whether there has as yet been an injury" [internal quotation marks omitted] ). Labeling the statute as such does not resolve the issue at hand, however, because this court in Baxter explicitly rejected the notion that "statutes of repose ... are always substantive"; Baxter v. Sturm, Ruger & Co. , supra, at 341, 644 A.2d 1297 ; instead, concluding that statutes of repose should be treated the same as statutes of limitations for choice of law purposes because they both "serve the same public policy of avoiding the litigation of stale claims." Id., at 344, 644 A.2d 1297 . Under Connecticut's choice of law rules, the dispositive inquiry is not whether the statute at issue properly is characterized as a statute of repose or a statute of limitations, but whether the "nature of the underlying right that forms the basis of the lawsuit" existed at common law. 12 Id., at 347, 644 A.2d 1297 . Because Delaware law recognizes a common-law claim for unjust enrichment, § 17-607 (c) of DRULPA is a procedural limitation on that preexisting right to relief.

The defendants next contend that the choice of law provision in the limited partnership agreement is worded broadly to include all of Delaware's procedural law as well as its substantive law. We disagree. "Choice of law provisions in contracts are generally understood to incorporate only substantive law, not procedural law such as statutes of limitation[s]." Federal Deposit Ins. Corp. v. Petersen , 770 F.2d 141 , 142 (10th Cir. 1985). Thus, "[a]bsent an express statement that the parties intended another state's limitations statute to apply, the procedural law of the forum governs time restrictions ...." Cole v. Mileti , 133 F.3d 433 , 437 (6th Cir.), cert. denied, 525 U.S. 810 , 119 S. Ct. 42 , 142 L. Ed. 2d 32 (1998) ; see also Gluck v. Unisys Corp. , 960 F.2d 1168 , 1179 (3d Cir. 1992) ("[c]hoice of law provisions in contracts do not apply to statutes of limitations, unless the reference is express"); Des Brisay v. Goldfield Corp. , 637 F.2d 680 , 682 (9th Cir. 1981) (Choice of law "clauses generally do not contemplate application to statutes of limitation. [Limitation] periods are usually considered to be related to judicial administration and thus governed by the rules of local law, even if the substantive law of another jurisdiction applies.");

Portfolio Recovery Associates, LLC v. King , 14 N.Y.3d 410 , 416, 927 N.E.2d 1059 , 901 N.Y.S.2d 575 (2010) ("Choice of law provisions typically apply to only substantive issues ... and statutes of limitations are considered procedural because they are deemed as pertaining to the remedy rather than the right .... There being no express intention in the agreement that Delaware's statute of limitations was to apply to this dispute, the choice of law provision cannot be read to encompass that [limitation] period." [Citations omitted; internal quotation marks omitted.] ).

The choice of law provision in the limited partnership agreement does not mention, much less expressly incorporate, the three-year limitation period in § 17-607 (c) of DRULPA. 13 A "standard choice of law provision," such as the one at issue in the present case, which does not mention the procedural law of another state, "will not be interpreted as covering a statute of limitations." Federal Deposit Ins. Corp. v. Peterson , supra, 770 F.2d at 142-43 ; see also Generali-U.S. Branch v. Lachel & Associates, Inc. , Docket No. 3:16-cv-595-DJH, 2017 WL 6999998 , *3 (W.D. Ky. August 7, 2017) (holding that "the phrase 'governed by' is not an express statement indicating that Indiana law should apply to the statute of limitations"); American Energy Technologies, Inc. v. Colley & McCoy Co. , Docket No. CIV A. 98-398 MMS, 1999 WL 301648 , *2 (D. Del. April 15, 1999) (holding that choice of law provision, providing in relevant part that "[t]he agreement shall be interpreted according to the laws of the [c]ommonwealth of Virginia," did "not expressly provide for the laws of the [c]ommonwealth of Virginia to apply to the statute of limitations," and, therefore, "Virginia's five-year statute of limitations for contract cases [was] inapplicable").

Finally, the defendants contend that § 17-607 (c) of DRULPA must apply to the plaintiff's unjust enrichment claims pursuant to the Connecticut Uniform Limited Partnership Act (CULPA), General Statutes § 34-9 et seq., which provides in relevant part that "[s]ubject to the Constitution of this state ... the laws of the state under which a foreign limited partnership is organized govern its organization and internal affairs and the liability of its limited partners ...." General Statutes § 34-38f (1). Again, we disagree. Consistent with CULPA and the choice of law provision in the limited partnership agreement, Delaware law governs the substantive liability of the defendants with respect to the plaintiff's unjust enrichment claims. As we have explained, however, the time in which to file a Delaware unjust enrichment action is a matter of judicial administration and procedure that is controlled by Connecticut law. Therefore, Connecticut law governs the timeliness of the plaintiff's claims.

III

Having concluded that Connecticut law governs the timeliness of the plaintiff's unjust enrichment claims, we next address the defendants' contention that the judgment of the trial court may be affirmed on the alternative ground 14 that the plaintiff's claims are barred by the three-year statute of limitations in § 52-577 generally applicable to tort actions. 15 The plaintiff responds that § 52-577 is inapplicable to the present case because unjust enrichment is not a tort but an equitable claim for relief. The plaintiff contends that its unjust enrichment claims are not subject to any limitation period at all or, in the alternative, are subject to the six-year statute of limitations applicable to contract actions. See General Statutes § 52-576 (a). 16

As a preliminary matter, we note that the trial court did not reach the issue of which statute of limitations, if any, governs the plaintiff's unjust enrichment claims under Connecticut law. When a trial court has not ruled on all of the grounds raised in a motion for summary judgment, we have the discretion either to "remand for further trial court proceedings" or "to consider whether, as a matter of law, the trial court's judgment can be sustained on ... [alternative] grounds." Skuzinski v. Bouchard Fuels, Inc. , 240 Conn. 694 , 703, 694 A.2d 788 (1997) ; see also Vollemans v. Wallingford , 103 Conn. App. 188 , 219, 928 A.2d 586 (2007) ("[a]lthough the trial court did not rule on those [alternative] grounds for summary judgment, it is within our discretion to do so on appeal"), aff'd, 289 Conn. 57 , 956 A.2d 579 (2008). Because the issue presents a pure question of law 17 that has been briefed extensively by the parties on appeal, the interest of judicial economy induces us to consider whether the plaintiff's unjust enrichment claims are barred by the three-year limitation period in § 52-577.

As explained in part II of this opinion, unjust enrichment is not a legal claim sounding in either tort or contract-it is an equitable claim for relief. As an equitable claim, its timeliness is not subject to a statute of limitations but, rather, to the equitable doctrine of laches. See Dunham v. Dunham , 204 Conn. 303 , 326-27, 528 A.2d 1123 (1987) (holding that plaintiff's equitable claim for relief was not barred by three-year statute of limitations in § 52-577 ), overruled in part on other grounds by Santopietro v. New Haven , 239 Conn. 207 , 213 n.8, 682 A.2d 106 (1996) ; see also Government Employees Ins. Co. v. Barros , 184 Conn. App. 395 , 399, 401, 195 A.3d 431 (2018) (recognizing that "[s]tatutes of limitations do not apply in a strict fashion to causes of action arising in equity," and when "the plaintiff's claim sounds only in equity, not in law or in both law and equity ... the plaintiff's claim is not subject to any statute of limitations, let alone the same statutes of limitations applicable to the underlying claims" [footnote omitted] ). In an action for equitable relief, a court is not "bound to apply the statute of limitations that governs the underlying cause of action. In fact, in an equitable proceeding, a court may provide a remedy even though the governing statute of limitations has expired, just as it has discretion to dismiss for laches an action initiated within the period of the statute."

Dunham v. Dunham , supra, at 326, 528 A.2d 1123 . "Although courts in equitable proceedings often look by analogy to the statute of limitations to determine whether, in the interests of justice, a particular action should be heard, they are by no means obliged to adhere to those time limitations." Id., at 326-27, 528 A.2d 1123 ; see Certain Underwriters at Lloyd's, London v. Cooperman , 289 Conn. 383 , 411, 957 A.2d 836 (2008) (concluding that plaintiffs' equitable claims were time-barred because its legal claims were time-barred under statute of limitations). As equitable claims for relief, the plaintiff's unjust enrichment claims are not barred by the three-year limitation period in § 52-577.

The defendants contend 18 that, even under the doctrine of laches, the three-year limitation period in § 52-577 should apply to this action by analogy because the plaintiff "has no excuse whatsoever for waiting until 2013 to seek recovery of payments made in 2008," and the defendants have suffered prejudice as a consequence of the plaintiff's delay because "SV Fund recouped the alleged loss, SV Fund no longer exists, and all of the other partners have received their distributions." To prevail on the affirmative defense of laches, the defendants must establish, first, that there was an inexcusable delay and, second, that the delay "prejudiced the defendant[s].... The mere lapse of time does not constitute laches ... unless it results in prejudice to the defendant[s] .... A conclusion that a plaintiff has been guilty of laches is one of fact for the trier and not one that can be made by this court, unless the subordinate facts found make such a conclusion inevitable as a matter of law." (Citations omitted; internal quotation marks omitted.) Papcun v. Papcun , 181 Conn. 618 , 620-21, 436 A.2d 282 (1980). The trial court made no factual findings regarding the defendants' special defense of laches, and, in the absence of subordinate facts, we decline to address the issue. We therefore remand this case to the trial court for consideration of the defendants' seventh special defense of laches, as well as the remaining grounds for summary judgment raised in the defendants' August 12, 2016 motion for summary judgment.

The judgment is reversed and the case is remanded for further proceedings according to law.

In this opinion the other justices concurred.
