Opinion
SULLIVAN, J.The plaintiff, Ronald Gold, a state employee, brought this action on his own behalf and on behalf of all others similarly situated, against the defendants, John G. Rowland, the former governor of the state of Connecticut, and the state of Connecticut (collectively referred to as the state), and also against Anthem, Inc., Anthem Health Care Plans, Inc., doing business as Anthem Blue Cross and Blue Shield of Connecticut, Anthem East, Inc., and Anthem Insurance Companies, Inc. (collectively referred to as the insurance company defendants), alleging that the state had received approximately 1.6 million shares of stock in Anthem, Inc., that should have been distributed to the plaintiff and other state employees. The state filed a motion to dismiss the complaint on the ground that it was barred by the doctrine of sovereign immunity. The trial court granted the state’s motion to dismiss with respect to eleven of the complaint’s seventeen counts against the state, but denied the motion with respect to the counts alleging that the state had taken the plaintiffs property in violation of article first, § 11, of the constitution of Connecticut1 and had violated his due process rights under article first, § 8, of the constitution of Connecticut.2 The trial court also denied the motion to dismiss the plaintiffs interpleader claims under General *190Statutes § 52-484.3 The state then appealed,4 claiming that the trial court improperly had denied its motion to dismiss the counts alleging constitutional violations. The insurance company defendants filed a cross appeal claiming that the trial court improperly had concluded that the plaintiff did not have a colorable claim of an unconstitutional taking under a theory of individual entitlement and that the trial court improperly had dismissed the plaintiffs constructive trust claims. The plaintiff also filed a cross appeal claiming that the trial court improperly had granted the state’s motion to dismiss with respect to his constructive trust and resulting trust claims.5 6With respect to the state’s appeal, we conclude that the trial court improperly denied the state’s motion to dismiss the plaintiffs claims under the state constitution. With respect to the insurance company defendants’ cross appeal, we conclude that they lack standing to raise their claims. Finally, with respect to the plaintiffs cross appeal, we conclude that *191the trial court properly dismissed the plaintiffs claims of a constructive trust and a resulting trust.6 Accordingly, we reverse in part and affirm in part the judgment of the trial court.
The record reveals the following undisputed facts and procedural history. On July 31,1997, Anthem Insurance Companies, Inc. (Anthem Insurance), a mutual insurance company organized under Indiana law, merged with Blue Cross and Blue Shield of Connecticut, Inc. (Blue Cross), a mutual insurance company organized under Connecticut law. Under the plan and joint agreement of merger, Anthem Insurance was designated as the company that would survive the merger. In connection with the merger, Blue Cross formed a subsidiary, Anthem Health Care Plans, Inc., doing business as Anthem Blue Cross and Blue Shield of Connecticut (Anthem Health Care), to carry on the health insurance business of Blue Cross after the merger.
Under Anthem Insurance’s premerger membership rules, each individual holder of a certificate of coverage under a fully insured group health insurance policy was an individual member of the company. The employer that had procured the coverage was not a member. Blue Cross’ premerger bylaws provided in relevant part that, “[i]n the case of a group insurance policy, the group as a whole shall be considered one policyholder, and such policyholder’s rights as a [vjoting [m] ember shall be exercised by the individual designated in, or pursuant to, such policy to act for the group for voting purposes. Individual members of the group who have been issued certificates shall not be considered [vjoting [m] embers. . . .’’On March 26, 1997, Blue Cross designated an entity identified as “00042-243, [s]tate of Connecticut, [ojffice of [comptroller, 55 Elm Street, Hartford, CT *19206106” as the voting member for a group health insurance policy, known as the care plus policy, issued by Blue Cross for 571 retired state employees.
On June 18, 2001, the board of directors of Anthem Insurance approved a plan of conversion from a mutual insurance company to a stock corporation (plan of conversion) under Indiana law.7 The Indiana insurance commissioner approved the plan of conversion with an effective date of November 2,2001. Thereafter, Anthem, Inc., was organized as a stock corporation under Indiana law to be the parent corporation of Anthem Insurance. Under the plan of conversion, upon the effective date of the demutualization, all of the outstanding capital stock of Anthem Insurance would be issued to Anthem, Inc., and “[e]ligible [statutory [m]ember[s]”8 of Anthem Insurance would become entitled to receive stock in Anthem, Inc., or cash, in exchange for the extinguishment of their membership interests in Anthem Insurance. The plan of conversion defined “[e]ligible [statutory [m]ember” as “a [p]erson who (a) is a [statutory [m] ember of Anthem Insurance on the [a]doption [d]ate [i.e., June 18, 2001] and continues to be a [statutory [m]ember of Anthem Insurance on the [effective [d]ate [i.e., November 2, 2001], and (b) has had continuous health care benefits coverage with the same company during the period between those two dates under any [p]olicy or [p]olicies without a break *193of more than one day.” During the period from June 18, 2001, through November 2, 2001, the plaintiff and other state employees and retirees continuously held certificates of coverage under a group policy that the state had procured from Anthem Health Care in 1999 (1999 group policy).
In late 2001 and early 2002, Anthem Insurance distributed 1,645,773 shares of Anthem, Inc., stock to the state, on the basis of its determination that the state was an eligible statutory member under the 1999 group policy. On January 14,2002, Nancy Wyman, the state comptroller, sent a letter to then governor John G. Rowland requesting the establishment of a “fiduciary agency fund” for the stock and any proceeds derived therefrom. Wyman explained that “the state has taken custody of an asset to which it does not have a clear and unfettered right of ownership” and asked that the stock and proceeds be maintained in the fund “pending the resolution of all ownership issues.” Governor Rowland approved the establishment of the fund. Thereafter, Attorney General Richard Blumenthai provided an opinion to the state treasurer in which he concluded that the state owned the Anthem, Inc., stock and that, “[ujnless and until a court or administrative tribunal directs otherwise, [the treasurer] ha[s] the authority to receive and manage the stock consistent with [her] statutory and fiduciary duties.” He further stated that, “[a]s a prudential matter, the proceeds from the liquidation of the stock may be maintained in [the fiduciary agency] fund until the legal issues are resolved.” Thereafter, the state sold the stock for $93,768,950.
In January, 2002, the plaintiff filed a two count inter-pleader action against the state and the insurance company defendants alleging that he and others similarly situated were entitled to receive the Anthem, Inc., stock pursuant to the plan of conversion. In April, 2002, the plaintiff filed a motion for order compelling the state *194and the insurance company defendants to deposit the proceeds from the sale of the stock into the court. The trial court declined to rule on the motion, but issued a scheduling order in which it ordered that all “funds received for the sale of stock received from the [insurance company defendants] . . . shall remain sequestered until such time as this court shall determine the legality of so holding them, the necessity thereof to preserve the plaintiff’s interest in satisfying any judgment that may be entered in his favor in this case, and any other matter the parties may raise as to the appropriateness of their continuing sequestration.”
In May, 2002, the parties entered into a stipulation in which they noted that the trial court had entered “an interim order . . . solely to preserve the status quo pending its determination of the [m]otion [for order compelling the state and the insurance company defendants to deposit disputed property into court].” They agreed that “[a]ny transfer or use by the [s]tate of some or all of the proceeds [from the sale of the Anthem, Inc., stock] shall not result in the surrender, waiver, change, diminution or loss of any rights or claims of right or the enhancement of any defense of any party by virtue of such transfer or use as they may have existed or shall exist any time hereafter.” The trial court then vacated the interim order. Effective July 1, 2002, the legislature authorized the state treasurer to credit the proceeds from the sale of the stock held in the fiduciary agency fund to the general fund. See Public Acts, Spec. Sess., May, 2002, No. 02-1, § 39. Thereafter, the state transferred the proceeds to the general fund and spent them.
In November, 2002, the plaintiff filed a second amended complaint in which he raised interpleader claims pursuant to § 52-484 alleging that, under the plan of conversion, he and other similarly situated state employees were entitled to the stock that the insurance *195company defendants had issued to the state (counts one and two). In addition, the plaintiff claimed that: the state had been unjustly enriched by receipt of the Anthem, Inc., stock (counts three and four); the state held the stock or its cash equivalent in constructive trust for the plaintiff and others similarly situated (counts five and six); the state held the stock or its cash equivalent in resulting trust for the plaintiff and others similarly situated (count seven); the state had converted property rightfully owned by the plaintiff and others similarly situated (counts eight and nine); the state had failed to compensate the plaintiff and others similarly situated for the taking of the stock in violation of article first, § 11, of the constitution of Connecticut (counts ten and eleven); the state had taken the stock without providing due notice of the taking to the plaintiff and others similarly situated and without affording them the right to a hearing or other process in violation of article first, § 8, of the constitution of Connecticut (counts twelve and thirteen); the state had failed to compensate the plaintiff and others similarly situated for the taking of the stock in violation of the fifth and fourteenth amendments to the United States constitution9 and they were therefore entitled to compensation under 42 U.S.C. § 198310 (counts fourteen and fifteen); *196the state had taken the stock without providing due notice of the taking to the plaintiff and others similarly situated and without affording them the right to a hearing or other process in violation of the fifth and fourteenth amendments to the United States constitution11 and they were therefore entitled to compensation under 42 U.S.C. § 1983 (counts sixteen and seventeen); and the insurance company defendants had breached their duties to the plaintiff and others similarly situated by failing to issue the stock or its cash equivalent to them (counts eighteen and nineteen).
Thereafter, the state filed a motion to dismiss the plaintiffs claims against it on the ground that the claims were barred by the doctrine of sovereign immunity. After a hearing, the trial court concluded that the common-law claims raised in counts three through nine of the complaint were barred by the doctrine of sovereign immunity and dismissed those counts. The court also dismissed the plaintiffs federal constitutional claims as set forth in counts fourteen through seventeen on the basis of the plaintiffs representation that he did not intend to pursue those claims.
With respect to the plaintiffs claims under the state constitution, the state had claimed in its motion to dismiss that the complaint did not set forth allegations that could support a finding that the state had taken the plaintiffs property in a constitutional sense because the plaintiff had not alleged that the state had taken affirmative action with respect to the stock or the proceeds from its sale. Rather, the state argued, the plaintiff had merely alleged that the state had received the stock from Anthem, Inc. The state further contended that the *197plaintiff had alleged only that he was entitled to receive generic stock or cash from Anthem, Inc., not that he was entitled to the specific stock that had been delivered to the state. Because the plaintiff was entitled to bring a contractual claim against Anthem, Inc., for delivery of the stock or its cash equivalent, the state argued, the state’s receipt of the stock had not deprived the plaintiff of anything. The trial court rejected these claims and agreed with the plaintiff that, because he had alleged that the stock that the state had received from Anthem Insurance belonged exclusively to him and to others similarly situated, the state’s physical retention of the property could constitute a taking.
The state had also claimed that, even if its mere retention of the stock could constitute a constitutional taking, the plaintiff had not alleged a taking because he had not alleged that he and others similarly situated had an ownership interest in the stock at the time of the alleged taking. The plaintiff contended that, to the contrary, he and others similarly situated had a legitimate entitlement to the stock in the state’s possession because: (1) as individual holders of certificates of insurance under the 1999 group policy from June 18, 2001, through November 2,2001, he and those on whose behalf he was suing all had been eligible statutory members of Anthem Insurance and, therefore, under the express provisions of the plan of conversion, they were individually entitled to receive personal distributions of stock or its cash equivalent from Anthem, Inc.; and (2) alternatively, under Blue Cross’ premerger bylaws, he and others similarly situated, as a “group as a whole,” had been the sole policyholder and, upon the merger of Anthem Insurance and Blue Cross and the subsequent demutualization of Anthem Insurance, the group as a whole became the eligible statutory member with the state as its voting representative.12
*198With respect to the plaintiffs first theory of entitlement, the trial court concluded that, even if the plaintiff and others similarly situated were individually entitled to receive the stock, the state had done nothing to interfere with that right and, therefore, its conduct could not have constituted a taking. With respect to the plaintiffs second group as a whole theory of entitlement, the court rejected the state’s argument that, because the “only property interest asserted by the plaintiff ... is [his] alleged right, under the plan of conversion, to receive an unknown quantity of [Anthem, Inc.] stock or cash from [Anthem, Inc.] upon the demutualization of Anthem Insurance,” the plaintiff had not alleged that the state had taken a discrete property interest. In support of this claim, the state had argued that Anthem, Inc.’s determination as to how much stock the state was to receive necessarily would be different from its determination as to how much stock the group as a whole would be entitled to receive. The trial court concluded that, because, apart from a fixed component of twenty-one shares per statutory member, the allocation of the stock was based on Anthem, Inc.’s profit and loss experience under the relevant policy, the amount of stock allocated to the group as a whole would have been no different than the amount allocated to the state. The court concluded that the plaintiff had made a color-able claim that the group as a whole was entitled to the stock that Anthem Insurance had delivered to the state and that the plaintiff could establish a taking at trial “provided only that [he] also proved that the relationship between the group as a whole and the state . . . was that of principal and agent.” (Internal quotation marks omitted.) Accordingly, the trial court denied *199the state’s motion to dismiss the plaintiffs claim of an unconstitutional taking under the state constitution under his group as a whole theory.
With respect to the plaintiffs due process claims under the state constitution, the trial court concluded that, in light of the plaintiffs valid claim of an unconstitutional taking, the plaintiff had made a colorable claim that he and others similarly situated were constitutionally entitled to procedures to ensure that they were aware of their rights to the stock, if any, or to a posttaking hearing to determine the amount of compensation that they should receive for the stock. Accordingly, the court denied the motion to dismiss these claims.
Finally, with respect to the plaintiffs interpleader claims under § 52-484, the trial court concluded that the claims were “merely procedural vehicles for obtaining a final judicial determination as to who owns the disputed stock and stock sales proceeds, and thus . . . their viability depends upon the viability of at least one of his other, substantive claims.” Because the plaintiff had raised viable substantive claims under the state constitution, the court denied the motion to dismiss with respect to the interpleader claims.
This appeal by the state and these cross appeals by the plaintiff and the insurance company defendants followed. See footnotes 4 and 5 of this opinion. The state claims on appeal that the trial court improperly denied its motion to dismiss the plaintiffs claim of an unconstitutional taking under the state constitution because: (1) the plaintiff had not alleged any agency relationship between the state and the plaintiff and others similarly situated in their capacity as a group as a whole under Blue Cross’ premerger bylaws; (2) the property held by the state is not identical to the property to which the plaintiff claims an entitlement; (3) the state’s passive receipt of property under a claim of right cannot consti*200tute an unconstitutional taking; and (4) the plaintiff was required to exhaust his remedies with the claims commissioner pursuant to General Statutes § 4-142 et seq., before bringing his takings claim. The plaintiff disputes these claims by the state and cross appeals from the trial court’s dismissal of his claims alleging a constructive trust and a resulting trust. The insurance company defendants also dispute the state’s claims on appeal and cross appeal from the trial court’s determination that the plaintiff had not raised a colorable claim of an unconstitutional taking under his individual theory of entitlement, as well as from that court’s dismissal of the plaintiffs constructive trust claims.
I
THE STATE’S APPEAL
We first address the state’s claim on appeal that the plaintiff neither alleged nor presented evidence that the state had received the Anthem, Inc., stock in its capacity as agent for the plaintiff and others similarly situated. We agree.13
We begin our analysis with the appropriate standard of review. “The standard of review for a court’s decision on a motion to dismiss is well settled. A motion to dismiss tests, inter alia, whether, on the face of the record, the court is without jurisdiction. . . . [0]ur review of the court’s ultimate legal conclusion and resulting [determination] of the motion to dismiss will be de novo. . . . When a . . . court decides a jurisdictional question raised by a pretrial motion to dismiss, it must consider the allegations of the complaint in their most favorable light. ... In this regard, a court must take the facts to be those alleged in the complaint, including those facts necessarily implied from the allegations, construing them in a manner most favorable *201to the pleader. . . . The motion to dismiss . . . admits all facts which are well pleaded, invokes the existing record and must be decided upon that alone.” (Citation omitted; internal quotation marks omitted.) Cogswell v. American Transit Ins. Co., 282 Conn. 505, 516, 923 A.2d 638 (2007). “The complaint, to survive the defense of sovereign immunity, must allege sufficient facts to support a finding of a taking of [property] in a constitutional sense . . . ,”14 Horak v. State, 171 Conn. 257, 261, 368 A.2d 155 (1976).
In the present case, the trial court concluded that the plaintiff could prevail on his claim of an unconstitutional taking if he could establish at trial that the state had acted as his agent when it received the Anthem, Inc., stock. In support of this conclusion, the trial court stated that, if the plaintiff were able to establish at trial that the group as a whole had “received collective membership rights in Anthem Insurance pursuant to [the care plus policy], including the right to receive a single joint distribution of stock or cash from [Anthem, Inc.] upon the demutualization of Anthem Insurance . . . then the plaintiff and his fellow class members would have established that their group as a whole was collectively entitled to receive all of the stock which [Anthem, Inc.] delivered to the state in exchange for the state’s assumed membership rights in Anthem Insurance pursuant to the care plus policy and the 1999 group policy, provided only that they also proved that the *202relationship between the group as a whole and the state with respect to those policies was that of principal and agent. In that event, the state’s receipt of the disputed stock would not have been in its personal capacity, in its own right or for its own benefit, but in its representative capacity, as the statutory member of Anthem Insurance on behalf of and for the benefit of the group as a whole. If such facts are proved at trial, then the state’s sale of the disputed stock and continuing retention of all proceeds from its sale for its own use would clearly constitute a taking, in the constitutional sense, of the plaintiffs and his fellow class members’ private property.”15 (Internal quotation marks omitted.)
According to the trial court, this theory was in contrast to the plaintiffs individual theory of entitlement, under which the plaintiff and others similarly situated “would logically have expected that such distributions would be made to them directly, not through the state or any other third party intermediary.” Thus, the trial court’s conclusion that the plaintiff could prevail under his group as a whole theory if he could establish an agency relationship between himself and the state was premised on that court’s determination that, under the *203group as a whole theory, unlike the plaintiffs individual theory of entitlement, the plaintiff and others similarly situated logically would have expected to receive a single joint distribution of stock rather than individual distributions.
The state contends that the trial court improperly concluded that the plaintiff could prevail on his claim of an unconstitutional taking at trial if he could prove that the state received the stock in its capacity as an agent for the plaintiff and others similarly situated because the plaintiff did not allege that he and others similarly situated had an agency relationship with the state. Specifically, the state claims that the plaintiff failed to allege any facts capable of establishing a manifestation of his assent that the state would act on his behalf, any facts capable of establishing that the state agreed to receive the stock on his behalf or any facts capable of establishing that the parties understood that the plaintiff ultimately would be in control of the stock.16 The plaintiff responds that the trial court properly held that the issue of representative capacity was a question of fact to be determined at trial and that the plaintiff was not required to prove an agency relationship at this stage of the proceedings. We agree with the state.
The plaintiff neither alleged in his complaint nor presented any evidence to the trial court that Anthem Insurance in fact delivered the stock to the state in its *204capacity as the agent for the group as a whole. Rather, the plaintiffs complaint more reasonably is read as alleging that Anthem Insurance failed to deliver the stock to the state in its capacity as the agent for the group as a whole, in violation of Anthem Insurance’s obligations under the plan of conversion.17 Indeed, the plaintiff does not dispute that Anthem Insurance determined that the state was entitled to the stock as a statutory member in its own right and that the plaintiff and others similarly situated were not statutory members and were not entitled to the stock. Nor does he dispute that Anthem Insurance delivered the stock to the state in its capacity as a statutory member in its own right. See footnote 17 of this opinion. He claims only that these actions violated the plan of conversion.
Thus, although the trial court may have been correct that the plaintiff had made a colorable claim that the group as a whole was entitled to the stock, and that the plaintiff had a reasonable expectation under the plan of conversion that Anthem Insurance would deliver a single, joint distribution of the stock to the group and that the state was the logical representative of the group for the purpose of receiving the stock, in the absence of any allegation that Anthem Insurance in fact delivered the stock to the state in its capacity as the agent for the plaintiff and others similarly situated, we must conclude that the trial court improperly determined that *205the plaintiff could prove this fact at trial. See Cogswell v. American Transit Ins. Co., supra, 282 Conn. 516 (“[t]he motion to dismiss . . . admits all facts which are well pleaded, invokes the existing record and must be decided upon that alone” [internal quotation marks omitted]). Accordingly, we conclude that the trial court improperly denied the state’s motion to dismiss the plaintiffs claim of an unconstitutional taking under the state constitution on this ground. Because the plaintiffs due process claims under the state constitution are premised on his taking claims, we further conclude that the trial court improperly denied the state’s motion to dismiss those claims.18
*206II
THE INSURANCE COMPANY DEFENDANTS’ CROSS APPEAL
As we have indicated previously herein, the trial court effectively treated each count of the plaintiffs complaint alleging violations of the state constitution as two separate counts alleging separate theories of recovery and concluded that his claims under the individual theory of entitlement must be dismissed. In their cross appeal, the insurance company defendants claim that the trial court improperly dismissed those claims. They contend that, regardless of whether the state acted as an agent for the plaintiff and others similarly situated, the plaintiff raised a valid claim of an unconstitutional taking under both his individual theory of entitlement and his group as a whole theory of entitlement because, if a trier of fact ultimately were to determine that the plaintiff and other similarly situated state employees are the true owners of the stock, the state’s retention of the stock or the proceeds from its sale would unconstitutionally exclude the true owners from its use and possession. Thus, the insurance company defendants challenge the trial court’s conclusion that, in the *207absence of an agency relationship, the state could not have interfered unconstitutionally with the plaintiff’s property rights. The insurance company defendants also claim that the trial court improperly dismissed the plaintiffs constructive trust and resulting trust claims on the ground that the doctrine of sovereign immunity does not bar claims for declaratory or injunctive relief. The state counters that the insurance company defendants lack standing to bring this cross appeal because the trial court’s dismissal of the plaintiffs claims against the state did not affect any specific personal or legal interest of the insurance company defendants. We agree with the state.
“Standing is the legal right to set judicial machinery in motion. One cannot rightfully invoke the jurisdiction of the court unless [one] has, in an individual or representative capacity, some real interest in the cause of action .... Standing is established by showing that the party claiming it is authorized by statute to bring suit or is classically aggrieved. . . . The fundamental test for determining [classical] aggrievement encompasses a well-settled twofold determination: first, the party claiming aggrievement must successfully demonstrate a specific personal and legal interest in the subject matter of the decision, as distinguished from a general interest, such as is the concern of all the members of the community as a whole. Second, the party claiming aggrievement must successfully establish that the specific personal and legal interest has been specially and injuriously affected by the decision. . . . Aggrievement is established if there is a possibility, as distinguished from a certainty, that some legally protected interest . . . has been adversely affected.” (Citation omitted; internal quotation marks omitted.) Briggs v. McWeeny, 260 Conn. 296, 308-309, 796 A.2d 516 (2002). “If a party is found to lack standing, the court is without subject matter jurisdiction to determine *208the cause. ... A determination regarding a trial court’s subject matter jurisdiction is a question of law.” (Internal quotation marks omitted.) Fort Trumbull Conservancy, LLC v. Alves, 286 Conn. 264, 271, 943 A.2d 420 (2008).
The state claims that the insurance company defendants lack standing to cross appeal from the dismissal of the plaintiffs claims against the state because the insurance company defendants have raised no claims against the state. Because the plaintiffs claims against the insurance company defendants are entirely distinct from his claims against the state, the state argues, the dismissal of the plaintiffs claims against the state does not affect the insurance company defendants. In response, the insurance company defendants contend that, because the practical effect of the dismissal of the plaintiffs claims against the state is to expose the insurance company defendants to the risk of a double recovery of the value of the stock, they have a specific interest in keeping the state as a party in the case.
We recognize that, as a practical matter, permitting the plaintiff to pursue his claims against the state could reduce the insurance company defendants’ risk of exposure to multiple recoveries. We also recognize that their interest in avoiding multiple recoveries against them probably would be sufficient to confer standing on them to bring a claim against the state, which are the claims at issue in the insurance company defendants’ cross appeal.19 We conclude, however, that the insurance company defendants have no legally protectible interest in the plaintiffs claims against the state. As the state points out, the plaintiff could have brought a claim for the stock solely against the insurance company defen*209dants and he could withdraw his claims against the state at will.20 We conclude, therefore, that the dismissal of the plaintiffs claims against the state did not deprive the insurance company defendants of anything in which they had “a specific personal and legal interest . . . .” Briggs v. McWeeny, supra, 260 Conn. 308. Accordingly, we conclude that the insurance company defendants lack standing to bring their cross appeal from the judgment of the trial court dismissing the plaintiffs constitutional claims against the state.21
*210III
THE PLAINTIFFS CROSS APPEAL
In Ids cross appeal, the plaintiff claims that the trial court improperly dismissed his constructive trust and resulting trust claims22 on the ground that they were barred by the doctrine of sovereign immunity. The plaintiff contends that the claims come within the exception to that doctrine for claims of injunctive relief.23 The state counters that this exception applies only when the plaintiff has alleged that the government has acted in excess of its statutory authority or pursuant to an unconstitutional statute. In turn, the plaintiff disputes the state’s claim and also claims that, even if the exception is limited in this way, the state acted in excess of its statutory authority when it accepted the Anthem, Inc., stock. Because we agree with the state that the exception to the doctrine of sovereign immunity is lim*211ited to actions by the state in excess of its statutory authority or pursuant to an unconstitutional statute and disagree with the plaintiff that the state acted in excess of its statutory authority when it accepted the stock, we conclude that the trial court properly dismissed these claims.
We begin with the standard of review. “Sovereign immunity relates to a court’s subject matter jurisdiction over a case, and therefore presents a question of law over which we exercise de novo review. ... In so doing, we must decide whether [the trial court’s] conclusions are legally and logically correct and find support in the facts that appear in the record. . . . The principle that the state cannot be sued without its consent, or sovereign immunity, is well established under our case law. ... It has deep roots in this state and our legal system in general, finding its origin in ancient common law.” (Internal quotation marks omitted.) DaimlerChrysler Corp. v. Law, 284 Conn. 701, 711, 937 A.2d 675 (2007). “Exceptions to this doctrine are few and narrowly construed under our jurisprudence.” (Internal quotation marks omitted.) Id.
In support of his claim on cross appeal, the plaintiff cites this court’s statement in Bloom v. Gershon, 271 Conn. 96, 107, 856 A.2d 335 (2004), that “the state cannot use sovereign immunity as a defense in an action for declaratory or injunctive relief.” (Internal quotation marks omitted.) See also Pamela B. v. Ment, 244 Conn. 296, 328, 709 A.2d 1089 (1998) (“[t]he state is subject to suit without consent ... in a suit for injunctive relief when the action does not defeat the purpose of the doctrine of sovereign immunity by undue interference with governmental functions” [internal quotation marks omitted]); Krozser v. New Haven, 212 Conn. 415, 421, 562 A.2d 1080 (1989) (“Sovereign immunity does not bar suits against state officials acting in excess of their statutory authority or pursuant to an unconstitutional *212statute. ... In addition, the state cannot use sovereign immunity as a defense in an action for declaratory or injunctive relief.” [Citations omitted; internal quotation marks omitted.]), cert. denied, 493 U.S. 1036, 110 S. Ct. 757, 107 L. Ed. 2d 774 (1990). The state counters that the trial court properly concluded that, under Doe v. Heintz, 204 Conn. 17, 31, 526 A.2d 1318 (1987), actions for declaratory and injunctive relief may be brought without the consent of the state only when the plaintiff alleges that the state officials had acted in excess of their statutory authority or pursuant to an unconstitutional statute. See id. (“[sovereign immunity does not bar suits against state officials acting in excess of their statutory authority or pursuant to an unconstitutional statute”); see also Miller v. Egan, 265 Conn. 301, 314, 828 A.2d 549 (2003) (“a plaintiff seeking to circumvent the doctrine of sovereign immunity must show that ... in an action for declaratory or injunctive relief, the state officer or officers against whom such relief is sought acted in excess of statutory authority, or pursuant to an unconstitutional statute” [internal quotation marks omitted]). We agree with the state.
This court previously has stated that “[t]he practical and logical basis of the doctrine [of sovereign immunity] is today recognized to rest ... on the hazard that the subjection of the state and federal governments to private litigation might constitute a serious interference with the performance of their functions and with their control over their respective instrumentalities, funds, and property. . . . [A]dherence to the doctrine of sovereign immunity does not mean [however] that all suits against government officers, since they are in effect suits against the government, must be barred. ... In those cases in which it is alleged that the defendant officer is proceeding under an unconstitutional statute or in excess of his statutory authority, the interest in the protection of the plaintiffs right to be free from the *213consequences of such action outweighs the interest served by the sovereign immunity doctrine. Moreover, the government cannot justifiably claim interference with its functions when the acts complained of are unconstitutional or unauthorized by statute. On the other hand, where no substantial claim is made that the defendant officer is acting pursuant to an unconstitutional enactment or in excess of his statutory authority, the purpose of the sovereign immunity doctrine requires dismissal of the suit for want of jurisdiction.” (Citations omitted; internal quotation marks omitted.) Horton v. Meskill, 172 Conn. 615, 624, 376 A.2d 359 (1977).
This court also has stated that, as a general matter, “a court may tailor declaratory and injunctive relief so as to minimize . . . interference [with the state’s performance of its functions], and ... to afford an opportunity for voluntary compliance with the judgment . . . .” (Internal quotation marks omitted.) Miller v. Egan, supra, 265 Conn. 314. The plaintiff has not cited, however, and our research has not revealed, any case in which this court has concluded that a claim for injunctive relief that did not involve conduct by the state in excess of its statutory authority or pursuant to an unconstitutional statute was not barred by sovereign immunity. Indeed, the cases are to the contrary. See, e.g., C. R. Klewin Northeast, LLC v. Fleming, 284 Conn. 250, 259-67, 932 A.2d 1053 (2007) (mandamus action in which plaintiff sought order requiring state to pay plaintiff pursuant to settlement agreement did not come within “in excess of statutory authority” exception to sovereign immunity in absence of statute requiring state to implement settlement agreements); Alter & Associates, LLC v. Lantz, 90 Conn. App. 15, 22-23, 876 A.2d 1204 (2005) (alleged failure of state to honor regulation concerning obligations to contract bidders, without more, did not meet “in excess of statutory authority” *214exception to sovereign immunity doctrine for equitable claims). Accordingly, in light of the language in Horton v. Meskill, supra, 172 Conn. 624, indicating that the exception to the doctrine of sovereign immunity for claims of declaratory or injunctive relief is premised on the notion that a plaintiff has an important interest in being protected from government action in excess of its statutory authority or pursuant to an unconstitutional statute, while the government has no legitimate interest in being free from interference with such conduct, and pursuant to the principle that exceptions to the doctrine of sovereign immunity must be narrowly construed; see DaimlerChrysler Corp. v. Law, supra, 284 Conn. 711; we must reject the plaintiffs invitation to adopt the dictum in Doe v. Heintz, supra, 204 Conn. 31-32, Pamela B. v. Ment, supra, 244 Conn. 328, and Krozser v. New Haven, supra, 212 Conn. 421, suggesting that the exception may be applied to all claims of injunctive relief, regardless of whether the state has acted in excess of its statutory authority or pursuant to an unconstitutional statute.
The plaintiff also claims, however, that, even if there is no broad exception to the doctrine of sovereign immunity for all claims for injunctive relief, there is an exception for claims to property held by the state in an account that is separate from the general fund. See Fernandez v. Chardon, 681 F.2d 42, 59 (1st Cir. 1982) (“where state funds are held in a separate account . . . and an award limited to those funds will not affect the state’s budgetary decisions ... its consent to suit and waiver of sovereign immunity seem unnecessary” [citation omitted]), affd sub nom. Chardon v. Soto, 462 U.S. 650, 103 S. Ct. 2611, 77 L. Ed. 2d 74 (1983); see also Schiff v. Williams, 519 F.2d 257, 262 (5th Cir. 1975) (when fund was not property of state, but only had been entrusted to state pending outcome of appeal, claim against fund was not barred by eleventh amend*215ment to federal constitution); Conrad v. Perales, 92 F. Sup. 2d 175, 185 (W.D.N.Y. 2000) (burden on state to prove affirmative defense of sovereign immunity by establishing that it had transferred money into general fund); Morrow v. Sudler, 502 F. Sup. 1200, 1204 (D. Colo. 1980) (eleventh amendment did not bar claim to money obtained from private donors and held by state in separate fund for sole use of state historical society). The plaintiff contends that, because the proceeds from the sale of the stock are “segregated from the state’s general treasuiy, judgment for the plaintiff on the constructive and resulting trust counts . . . will not, in any way, result in the ‘disruption of government’ that the doctrine of sovereign immunity is designed to prevent.”
We agree with the general principle that “where the state will be unaffected by [a judgment in favor of the plaintiff], its consent to suit and waiver of sovereign immunity seem unnecessary.” (Emphasis added.) Fernandez v. Chardon, supra, 681 F.2d 59. That principle, however, does not apply in the present case. The trial court entered the interim order to sequester the proceeds from the sale of the stock pending resolution of the plaintiffs motion for order compelling the state and the insurance company defendants to deposit the proceeds from the sale of the stock into the court. In turn, the resolution of that motion with respect to the state was contingent on the resolution of the state’s motion to dismiss. If the court were to grant the state’s motion to dismiss all of the plaintiffs claims against it, it would be required to deny the motion for order compelling the state and the insurance company defendants to deposit the proceeds into the court with respect to the state because it would have no jurisdiction to order the state to do anything. See Graham v. Zimmerman, 181 Conn. 367, 373, 435 A.2d 996 (1980) (court lacks jurisdiction over nonparty). For the same reason, the court also would be required to vacate the interim *216order. Thus, the interim order was analogous to a temporary restraining order, the sole purpose of which was to preserve the status quo until the court could determine whether the plaintiffs claims against the state would survive the motion to dismiss and, therefore, could provide the basis for an interlocutory judgment of interpleader.24 If the substantive claims underlying the plaintiffs interpleader action were dismissed, the interpleader action would not he and the state would be entitled to use the proceeds in the fund immediately.25 On the other hand, if the interpleader action were to survive the motion to dismiss, the trial court presumably would grant the motion to compel the state to deposit the proceeds subject to the interim order into court pending resolution of the merits of the plaintiffs substantive claims.
Ultimately, however, the trial court vacated the interim order when the parties entered into the stipulation providing that the state could use the funds and that doing so would not affect any party’s rights. The plaintiff now contends that the trial court’s order and the subsequent stipulation preserving the parties’ rights manifested an agreement by the state that the proceeds of the sale of the Anthem, Inc., stock would be available for distribution to the plaintiff if he prevailed before the trial court. Similarly, the insurance company defendants claim that the state “covenanted to make [the proceeds from the sale of the stock subject to the interim order] *217available to the plaintiff should the court . . . find in the plaintiffs favor” in his action against them. Thus, the plaintiff and the insurance company defendants appear to contend that the stipulation was the functional equivalent of an interlocutory judgment of inter-pleader and that, by entering into it, the state effectively waived its sovereign immunity to the substantive claims underlying the interpleader action and agreed to pay the plaintiff should he prevail on those claims. The stipulation merely provided, however, that the state’s use of the proceeds would not affect any existing or future rights of the parties, including the right, created by the interim order, to have the proceeds available to satisfy a future judgment in favor of the plaintiff should the substantive claims against the state survive the motion to dismiss,26 Nothing in the stipulation suggests that it was intended to create new rights.
To the extent that the plaintiff claims that the state’s initial creation of the fiduciary agency fund somehow conferred on him and the other state employees a conditional property interest in the fund that will exist until his claim that he is entitled to the proceeds of the stock is judicially resolved, we disagree. The plaintiff has made no claim that the state was legally obligated to create the fund instead of placing the proceeds immediately in the general treasury,27 and we cannot perceive *218how the state’s voluntary and unilateral creation of the fund could confer any rights on any individual or group. Thus, even if, as a matter of internal accounting, the state chooses to maintain a separate account for the proceeds from the sale of the stock until the merits of all claims against the proceeds are resolved, neither the plaintiff nor the insurance company defendants will have any property interest in that account in the absence of any pending claims against the state.
In the cases relied on by the plaintiff in support of his claim that sovereign immunity does not bar his resulting trust and constructive trust claims because a judgment that he is entitled to the proceeds from the sale of the stock cannot affect the state, the government would have been barred from using the money in the separate fund for general government purposes regardless of the outcome of the case.28 Because that is not the case here, and it is clear that a judgment against *219the state would affect the state’s treasury, we reject the plaintiffs claim.
Finally, we address the plaintiffs alternate argument that his claims of a resulting trust and a constructive trust fall into the exception to the doctrine of sovereign immunity for claims for injunctive relief because the state acted in excess of its statutory authority when it accepted the Anthem, Inc., stock. Specifically, the plaintiff contends that the state violated General Statutes § 5-25929 because the plain language of that statute suggests that each individual employee, and not the state, is a covered individual under the plan. He argues that this interpretation is bolstered by the language of General Statutes § 5-257 (c), which authorizes the state comptroller to procure life insurance for state employ*220ees and expressly provides that “[a]ny dividends or other refunds or rate credits shall inure to the benefit of the state and shall be applied to the cost of such insurance.” The fact that § 5-259 contains no such express language, the plaintiff argues, evinces a contrary legislative intent. See State v. Nixon, 231 Conn. 545, 563, 651 A.2d 1264 (1995) (when legislature uses language in one statute, absence of language in similar statute shows that legislature intended different result).
It is unclear to us whether the plaintiff is claiming that § 5-259 bolsters his claim that he and others similarly situated were entitled to receive the Anthem, Inc., stock under the plan of conversion, or whether he is claiming that, regardless of whether he and the other similarly situated state employees were entitled to receive the stock under the plan of conversion, § 5-259 required the state to deliver the stock to them. To the extent that the plaintiff is making the former claim, he has not provided any authority for the proposition that the “in excess of statutory authority” exception to the doctrine of sovereign immunity applies in situations where a particular statute may shed light on an issue that is not directly governed by the statute, but resolution of the issue in a way that is inconsistent with the statute would not undermine the purpose of the statute in any way. To the extent that he is claiming that the state actually violated § 5-259 when it failed to deliver the proceeds to him, the plaintiff raised no such claim in his complaint. Practice Book § 10-3 (a) provides that, “[w]hen any claim made in a complaint, cross complaint, special defense, or other pleading is grounded on a statute, the statute shall be specifically identified by its number.” The plaintiff has not explained why his statutory claim should not be barred under this rule of practice. Cf. Mazurek v. Great American Ins. Co., 284 Conn. 16, 28, 930 A.2d 682 (2007) (“[a]s long as the defendant is sufficiently apprised of the nature of the action . . . *221the failure to comply with the directive of Practice Book § 10-3 [a] will not bar recovery” [internal quotation marks omitted]); see also Moore v. Sergi, 38 Conn. App. 829, 841-42, 664 A.2d 795 (1995) (“[a] plaintiff may not allege one cause of action and recover on another” [internal quotation marks omitted]). We conclude, therefore, that this claim is barred.
Moreover, even if the plaintiffs claim that the state violated § 5-259 was not barred by Practice Book § 10-3 (a), we agree with the trial court’s alternate determination that it is meritless. The plaintiff concedes that nothing in § 5-259 sets forth the manner in which proceeds from the demutualization of an insurance company should be distributed. As the trial court recognized, the fact that, unlike § 5-257, § 5-259 does not provide that demutualization proceeds “shall inure to the benefit of the state and shall be applied to the cost of [health] insurance” does not imply that the legislature had a specific intent that the proceeds would be distributed to individual employees. Rather, it implies only that the legislature intended that the entitlement to such proceeds would be governed by the provisions of the insurance contracts and relevant law and that the legislature did not have any specific intent as to how any proceeds to which the state was contractually entitled should be used.
The plaintiff also claims that, even if the state did not violate any statute, in the absence of a statute specifically authorizing it to receive and retain the Anthem, Inc., stock, the state exceeded its statutory authority when it did so. As the plaintiff recognizes, however, the state is specifically authorized to enter into contracts to procure health insurance for state employees. See General Statutes § 5-259. Thus, the state is implicitly authorized to receive any benefits to which it is entitled under those contracts, including any demutualization proceeds.
*222To the extent that the plaintiff claims that the state acted in excess of its statutory authority when it received and retained the demutualization proceeds because it is not entitled to them under the plan of conversion, we conclude that this claim does not fall within the “in excess of statutory authority” exception to the doctrine of sovereign immunity. As we have explained, the entitlement to the Anthem, Inc., stock is governed by the plan of conversion, not by statute. In C. R. Klewin Northeast, LLC v. Fleming, supra, 284 Conn. 257-67, this court concluded that a mandamus action in which the plaintiff sought an order requiring the state to pay the plaintiff pursuant to a settlement agreement that the state had executed did not come within the “in excess of statutory authority” exception to sovereign immunity in the absence of any statute imposing on the state a mandatory duty to implement settlement agreements, even though the state plainly is not statutorily authorized to breach settlement agreements.30 See also Alter & Associates, LLCv. Lantz, supra, 90 Conn. App. 22-23 (alleged failure of state to honor regulation concerning obligations to contract bidders, without more, did not meet “in excess of statutory authority” exception to sovereign immunity doctrine for equitable claims); cf. Unisys Corp. v. Dept. of Labor, 220 Conn. 689, 697-98, 600 A.2d 1019 (1991) (sovereign immunity did not bar plaintiffs claim that *223state was barred from entering into contract because state failed to comply with statute requiring competitive bidding). Similarly, we conclude that, in the absence of any statute governing the entitlement to demutualization proceeds, the plaintiffs claim that the state wrongfully has received and retained those proceeds under the plan of conversion does not fall within the exception.
As we have indicated, the trial court concluded, and the plaintiff conceded, that if none of the plaintiffs substantive claims survived the state’s motion to dismiss, then his inteipleader action should also be dismissed. We have concluded that the trial court should have dismissed the plaintiffs claim of an unconstitutional taking under his group as a whole theory and that the court properly dismissed the plaintiffs constructive trust and resulting trust claims. Because there are no surviving substantive claims against the state, the inter-pleader action must be dismissed.31
The insurance company defendants’ cross appeal is dismissed. The judgment of the trial court denying the state’s motion to dismiss the plaintiffs claims under the state constitution and his interpleader action is reversed and the case is remanded to the trial court with direction to dismiss those claims and for further proceedings on the plaintiffs claims against the insurance company defendants. The judgment is affirmed in all other respects.

Such court shall hear and determine all questions which may arise in the case, may tax costs at its discretion and, under the rules applicable to an action of interpleader, may allow to one or more of the parties a reasonable sum or sums for counsel fees and disbursements, payable out of such fund or property; but no such allowance shall be made unless it has been claimed by the party in his complaint or answer.”
The state appealed from the judgment of the trial court to the Appellate Court, and we transferred the appeal to this court pursuant to General Statutes § 51-199 (c) and Practice Book § 65-1.

The plaintiffs two theories of entitlement to the Anthem, Inc., stock involve extremely complex factual and legal issues arising from the treat*198ment of the 1999 group policy and the care plus policy under the plan of conversion. Because of the complexity of those issues, and because the trial court’s conclusion that the plaintiff had made colorable claims under both theories is not at issue in this appeal, there is no need to explain the theories in detail here.
Accordingly, we need not consider its other claims on appeal.
“The word taken as used in . . . article first, § 11, of the Connecticut constitution means generally the exclusion of the owner from his private use and possession, and the assumption of the use and possession for the public purpose by the authority exercising the right of eminent domain.” (Internal quotation marks omitted.) Horak v. State, 171 Conn. 257, 261, 368 A.2d 155 (1976). “An inverse condemnation claim accrues when the purpose of government [action] and its economic effect on the property owner render the [action] substantially equivalent to an eminent domain proceeding.” (Internal quotation marks omitted.) Rural Water Co. v. Zoning Board of Appeals, 287 Conn. 282, 298, 947 A.2d 944 (2008).
“Generally, an agent is under a duty to repay or deliver to the principal money or property belonging to the principal which comes into the agent’s hands . . . while conducting the business of the agency, and an action will lie at the instance of the principal to recover such money.” 3 Am. Jur. 2d 689-90, Agency § 322 (2002). In such cases, the principal has an action for “money had and received,” which is the equivalent of the more modem action for unjust enrichment. See id., 690 n.l; 66 Am. Jur. 2d 747, Restitution and Implied Contracts § 172 (2001). Given these principles, it is not entirely clear to us why the trial court, having concluded that the plaintiffs claims against the state for unjust enrichment were barred by the doctrine of sovereign immunity, concluded that the plaintiffs claim that the state had received the stock as the agent for the group as a whole was not barred but, rather, constituted a colorable taking claim. We need not resolve this issue, however, because we agree with the state that the plaintiff has not made a colorable claim that the state received the stock in its capacity as the agent for the group as a whole.
“Under § 1 of 1 Restatement (Second) of Agency (1958), [a]gency is defined as the fiduciary relationship which results from manifestation of consent by one person to another that the other shall act on his behalf and subject to his control, and consent by the other so to act .... Thus, the three elements required to show the existence of an agency relationship include: (1) a manifestation by the principal that the agent will act for him; (2) acceptance by the agent of the undertaking; and (3) an understanding between the parties that the principal will be in control of the undertaking. . . . The existence of an agency relationship is a question of fact.” (Internal quotation marks omitted.) Wesley v. Schaller Subaru, Inc., 277 Conn. 526, 543, 893 A.2d 389 (2006).
The plaintiff alleged in his complaint that “[t]he stock which should have been issued to [the plaintiff] and [others similarly situated] pursuant to the [p]lan of [conversion . . . was issued by Anthem [Insurance] to [the state] . . . .”
In his brief to this court, the plaintiff characterizes this portion of his complaint as alleging that “the stock was issued to the state in lieu of to the plaintiff”; (emphasis added); not that it was issued to the state on behalf of the plaintiff. The plaintiff also states in his brief that Anthem Insurance “misdelivered” the stock to the state. Neither of these characterizations of Anthem Insurance’s conduct is consistent with a claim that Anthem Insurance delivered the stock to the state in its capacity as the plaintiffs agent.
The plaintiff has not challenged the trial court’s conclusion that he can prevail under his group as a whole theory only if he proves that the state acted as his agent when it received the stock. Rather, he argues that, if we agree with that conclusion, we should not reverse the judgment denying the state’s motion to dismiss on the basis of the state’s alternate claim that the state’s passive retention of property that it received from a third party cannot constitute a taking. Because we conclude that the trial court improperly determined that the plaintiff could prove an agency relationship at trial, we need not address this question.
The dissent contends that, in reaching our conclusion that the plaintiffs state constitutional claims should be dismissed because he has not alleged that the insurance company defendants transferred the stock to the state in its capacity as the agent for the plaintiff and others similarly situated, we confuse the procedural vehicle of a motion to dismiss with the procedural vehicle of a motion to strike. This court previously has held, however, that, when a complaint properly would have been subject to a motion to strike, and the plaintiff has made no showing that he could amend the complaint to avoid the deficiencies of the original complaint, the granting of a motion to dismiss instead of a motion to strike is harmless error. See, e.g., Fort Trumbull Conservancy, LLC v. Alves, 262 Conn. 480, 501-502, 815 A.2d 1188 (2003). Similarly, when a complaint properly would have been subject to a motion to strike and the plaintiff cannot cure the deficiencies in the complaint, we properly may reverse the trial court’s denial of a motion to dismiss rather than remand the case to the trial court so that the defendant may file a motion to strike that the trial court would be required to grant. The dissent does not dispute that the complaint in the present case properly would have been subject to a motion to strike and, because the plaintiff has not pointed to any evidence that Anthem Insurance transferred the stock to the state in its capacity as the agent for the plaintiff and others similarly situated, we must conclude that he cannot amend the complaint to cure its deficiencies. Accordingly, we properly may reverse the trial court’s ruling denying the motion to dismiss.
*206The dissent also places much emphasis on the evidence supporting an inference that the state was the agent for the plaintiff and others similarly situated and accuses the majority of ignoring this evidence. The dissent has pointed to no evidence, however, that the insurance company defendants transferred the stock to the state in its capacity as an agent and not in its capacity as a statutory member in its own right.
Finally, we recognize that, as the dissent points out, the insurance company defendants’ subjective belief that the state was the rightful owner of the stock has no bearing on whether the state, in fact, is the rightful owner of the stock. That question will be resolved in the ongoing litigation between the plaintiff and the insurance company defendants. Neither the dissent nor the plaintiff has provided any authority, however, for the proposition that, when property had been transferred by one party to another party, the intent and beliefs of the parties have no bearing on whether the transfer was made to the transferee in its capacity as an agent for another, or in its capacity as the purported rightful owner.
We express no opinion here as to the nature of any such claim, whether it would be time barred or ripe, or whether it would be barred by the doctrine of sovereign immunity.
Moreover, the plaintiff has not cross appealed from either the trial court’s determination that he cannot prevail on his claim of an unconstitutional taking under his theory of individual entitlement or from that court’s determination that he can prevail under his group as a whole theory only if he establishes that the state received the stock in its capacity as an agent for the plaintiff and others similarly situated. Rather, in response to the state’s claims on appeal, the plaintiff has claimed only that the trial court properly determined that he need not prove an agency relationship until the time of trial, that the state’s mere retention of the proceeds from the sale of the stock would constitute a taking under those circumstances and that his claim was not a contractual claim in a constitutional guise. We must presume, therefore, that the plaintiff believes that the trial court properly determined that proof of an agency relationship is a critical element of his taking claim. We have concluded that the plaintiff has not made a colorable claim that the state received the stock in its capacity as the plaintiffs agent. Thus, there is no reason to believe that the plaintiff would pursue his constitutional claims under either theory if this court were to rule in favor of the insurance company defendants on their cross appeal. Accordingly, even if the insurance company defendants had standing to raise their cross appeal from the trial court’s dismissal of the constitutional claims, the appeal would be moot.
The insurance company defendants’ reliance on Rose v. Freedom of Information Commission, 221 Conn. 217, 602 A.2d 1019 (1992), in support of their claim to the contrary is misplaced. This court held in Rose that the word “party” as used in General Statutes § l-21i (d), now General Statutes § 1-206 (d), includes intervenors in proceedings before the freedom of information commission for purposes of allowing an appeal by an aggrieved party. See id., 224-30. We did not hold that a person who did not have a specific legal interest in the subject matter of the decision could have standing to appeal.
Although we conclude that the insurance company defendants lack standing to cross appeal from the trial court’s dismissal of the plaintiffs constructive trust and resulting trust claims, we may consider the arguments raised by them in connection with the plaintiffs cross appeal. Cf. Kerrigan v. *210Commissioner of Public Health, 289 Conn. 135, 336 n. 15, 957 A.2d 407 (2008) (Zarella, J., dissenting) (“amicus is not at liberty to inject new issues in a proceeding . . . [but] is not confined solely to arguing the parties’ theories in support of a particular issue” [internal quotation marks omitted]).
“A constructive trust is the formula through which the conscience of equity finds expression. When property has been acquired in such circumstances that the holder of the legal title may not in good conscience retain the beneficial interest, equity converts him into a trustee. . . . The imposition of a constructive trust by equity is a remedial device designed to prevent unjust enrichment. . . . Thus, a constructive trust arises where a person who holds title to property is subject to an equitable duty to convey it to another on the ground that he would be unjustly enriched if he were permitted to retain it.” (Internal quotation marks omitted.) New Hartford v. Connecticut Resources Recovery Authority, 291 Conn. 433, 466, 970 A.2d 592 (2009).
“A resulting trust arises by operation of law at the time of a conveyance when the purchase money for property is paid by one party and the legal title is taken in the name of another.” (Internal quotation marks omitted.) Denby v. Commissioner of Income Maintenance, 6 Conn. App. 47, 53, 502 A.2d 954 (1986).
The trial court concluded that the plaintiffs claims of a constructive trust and a resulting trust “are not ‘dressed up’ claims for money damages, but proper claims for equitable relief.” The state does not directly challenge that conclusion on appeal.
“An interpleader proceeding typically involves two distinct parts, the first of which is an interlocutory judgment of interpleader. . . . An interlocutory judgment of interpleader, which determines whether inteipleader lies, traditionally precedes adjudication of the claims.” (Citation omitted.) State v. Burnaka, 61 Conn. App. 45, 50 n.11, 762 A.2d 485 (2000).
Indeed, after the court issued the interim order, the parties stipulated that the state could use the proceeds and that doing so would not affect any party’s rights or claims to them. The state then transferred the proceeds to the general fund. It is clear, therefore, that there were no restrictions on the state’s use of the funds other than the interim order, the continued existence of which was dependent on the survival of the plaintiffs claims against the state.
Indeed, during argument on the motion to dismiss, the trial court stated that it would take the view that it had been “flimflammed" if the proceeds from the sale of the stock were “not immediately available to be used for the purpose of an interpleader action in the event that the court determines that the action lies.” (Emphasis added.) When the attorney for the state contended that “you can’t ratchet [the stipulation] into . . . creating a viable interpleader claim,” the trial court responded that it was “certainly not” doing so. Thus, the trial court clearly recognized that the stipulation was not the functional equivalent of an interlocutory judgment of interpleader.
Indeed, the record suggests that the state had no such obligation. The attorney general provided an opinion to the state treasurer regarding this issue in which he stated that “[o]s a prudential matter, the proceeds from the liquidation of the stock may be maintained in this fund until the legal issues are resolved.” (Emphasis added.)
In Conrad v. Perales, supra, 92 F. Sup. 2d 178, the state had received refunds of medicaid payments from a number of skilled nursing facilities. The refunds included amounts that the plaintiffs, who were patients, had paid to the facilities. Id. The plaintiffs brought an action against the state claiming that the state had converted that portion of the refunds representing their payments. Id., 177. The court concluded that, when an action for the return of money is brought against the state, the burden is on the state to establish sovereign immunity by proving that it has not placed the money in a segregated account. Id., 185. Because the state had not established that it had placed the refunds in the general treasury, the court concluded that it was not entitled to immunity from suit under the eleventh amendment to the federal constitution. Id.
Although this case arguably supports the plaintiffs position that sovereign immunity does not bar a claim to money that has not been placed in the general fund, we are not persuaded by its reasoning. Even if the court in Conrad correctly determined that the burden was on the state to establish sovereign immunity and that it could do so by proving that it had not placed the money in a separate account, it would not follow that the state may be sued whenever the state has placed money in a separate account. As we explain in the body of this opinion, the purpose and ownership of the separate account are highly relevant to the question of whether an action seeking funds from the account will affect state operations and, therefore, be barred by sovereign immunity.
General Statutes § 5-259 (a) provides in relevant part: “The Comptroller, with the approval of the Attorney General and of the Insurance Commissioner, shall arrange and procure a group hospitalization and medical and surgical insurance plan or plans for (1) state employees .... The minimum benefits to be provided by such plan or plans shall be substantially equal in value to the benefits that each such employee . . . could secure in such plan or plans on an individual basis on the preceding first day of July. The state shall pay for each such employee . . . covered by such plan or plans the portion of the premium charged for such . . . employee’s individual coverage and seventy per cent of the additional cost of the form of coverage and such amount shall be credited to the total premiums owed by such employee . . . for the form of such member’s or employee’s coverage under such plan or plans. On and after January 1, 1989, the state shall pay for anyone receiving benefits from any such state-sponsored retirement system one hundred per cent of the portion of the premium charged for such . . . employee’s individual coverage and one hundred per cent of any additional cost for the form of coverage. The balance of any premiums payable by an individual employee . . . for the form of coverage shall be deducted from the payroll by the State Comptroller. The total premiums payable shall be remitted by the Comptroller to the insurance company or companies or nonprofit organization or organizations providing the coverage. The amount of the state’s contribution per employee for a health maintenance organization option shall be equal, in terms of dollars and cents, to the largest amount of the contribution per employee paid for any other option that is available to all eligible state employees included in the health benefits plan, but shall not be required to exceed the amount of the health maintenance organization premium.”
The insurance company defendants contend that C. R. Klewin Northeast, LLC, is distinguishable because, in that case, “the very existence of a property interest was in dispute,” while, in the present case, “there is no dispute . . . that a property interest exists and that it is owned either by the state or by some as yet undetermined state employees . . . .” For purposes of reviewing the trial court’s denial of the state’s motion to dismiss in C. R. Klewin Northeast, LLC, however, this court assumed the truth of the plaintiffs allegation that he had a contractually based property interest in the settlement proceeds. C. R. Klewin Northeast, LLC v. Fleming, supra, 284 Conn. 253 (“we take the facts as expressly set forth, and necessarily implied, in the plaintiffs complaint, construing them in the light most favorable to the pleader”).
The insurance company defendants request that, if the state prevails on its appeal and this court directs the trial court on remand to dismiss all claims against the state, we should direct the trial court to order the state to place the proceeds from the sale of the stock in a fiduciary agency fund pending the resolution of the plaintiffs claims against them. The dismissal of all claims against the state, however, means that the state will no longer be a party to this case. As we have indicated, neither this court nor the trial court has jurisdiction over persons or entities who are not parties to the action before it. See Graham v. Zimmerman, supra, 181 Conn. 373. Accordingly, we must deny this request.
