The dispositive issue in this appeal is the constitutionality of statutory procedures for the arbitration of motor vehicle disputes that, for manufacturers but not for consumers, severely limit the scope of judicial review for challenges to adverse arbitration determinations. This case is here pursuant to the remand that we ordered in Motor Vehicle Manufacturers Assn. of the United States, Inc. v. O’Neill, 203 Conn. 63, 523 A.2d 486 (1987) (Motor Vehicle Manufacturers Assn. I), to amplify a factual record that we deemed inadequate for consideration of a reservation raising a number of constitutional challenges to the validity of Public Acts 1984, No. 84-338, codified as General Statutes §§ 42-181 through 42-185, both in its initial form and as amended in 1985 (Lemon Law II).1 [85]*85Id., 80. Upon remand, and further factual stipulations by the parties,2 the trial court concluded that the plain[86]*86tiffs had failed to establish any violation of their state or federal constitutional rights, and accordingly ren[87]*87dered a judgment denying their request for declaratory or injunctive relief. We find error.
[88]*88The history of Lemon Law II, which is fully described in Motor Vehicle Manufacturers Assn. I, supra, 66-73, may be summarized as follows. In 1982, the legislature enacted General Statutes § 42-179 (Lemon Law I) in order to provide consumers of new motor vehicles additional substantive remedies for the enforcement of express warranties made by the manufacturers of such vehicles. The plaintiffs have not contested the constitutionality of Lemon Law I. Two years later, the legislature enacted Lemon Law II; General Statutes §§ 42-181 through 42-184; to provide such consumers an additional forum for the enforcement of express warranties. The new act authorizes consumers, but not manufacturers, to bring disputes about the performance of new motor vehicles to arbitration panels established by the department of consumer protection. General Statutes § 42-181 (a), (b), (c).3 The act also permits consumers, but not manufacturers, to reject an unfavorable arbitration decision and to institute a de [89]*89novo civil action. See General Statutes §§ 42-179 (i) and 42-181 (c). Neither consumers nor manufacturers may pursue Lemon Law claims before a jury.
The plaintiffs, in their third amended complaint filed after our remand in Motor Vehicle Manufacturers Assn. I, attacked the constitutionality of Lemon Law II on three grounds. They claimed that the act: (1) deprived them of their right to a trial by jury, in violation of article first, § 19, of the Connecticut constitution; (2) improperly limited the scope of judicial review, in violation of the separation of powers provisions of articles second and fifth, § 1, of the Connecticut constitution and the right of access to courts provision of article first, § 10, of the Connecticut constitution; and (3) denied them due process and equal protection of the laws, in violation of the fourteenth amendment to the United States constitution and article first, §§ 8, 10 and 20, of the Connecticut constitution, because the act requires them to pay a $250 filing fee to defend against the claims of consumers.
None of these contentions persuaded the trial court. With respect to the claimed right to a jury trial, the court found, upon an analysis of statistical data contained in a stipulation between the parties, that the proceedings conducted pursuant to Lemon Law II were essentially equitable rather than legal, because the remedies sought from the arbitration panels, and awarded by them, went beyond requests and awards for price refunds. Cf. Motor Vehicle Manufacturers Assn. I, supra, 79-80. On the basis of this finding, the court concluded that the plaintiffs were not entitled to a jury trial. The court concluded, furthermore, that the scope of judicial review afforded to arbitration awards under Lemon Law II passed constitutional muster because the act entitled the plaintiffs to the same scope of review presently afforded to the determinations of administrative agencies under the Uniform Adminis[90]*90trative Procedure Act. Finally, the court held that the act was not unconstitutional in requiring the manufacturer to pay the $250 filing fee; General Statutes § 42-181 (b); because it included a statutory provision permitting the waiver of any fee upon proof of economic hardship. General Statutes § 42-185. The court accordingly upheld the constitutionality of Lemon Law II.
In their appeal, the plaintiffs renew the same constitutional challenges that they raised at trial. Although we agree with the trial court’s resolution of the plaintiffs’ claimed right to a jury trial and to relief from filing fees, we disagree with the court’s construction of the act’s judicial review provisions as satisfying constitutional due process requirements, and hence find Lemon Law II unconstitutional in part.
I
The plaintiffs’ first challenge to Lemon Law II asserts that the statutory arbitration procedures contained in § 42-181 (c) unconstitutionally deprive them of their right to a trial by jury, in violation of article first, § 19, of the Connecticut constitution.4 In Motor Vehicle Manufacturers Assn. I, supra, 68-69, we described Lemon Law II as a statute that “provides supplemental remedies of repair, replacement and refund to facilitate the enforcement of express warranties made by [automobile] manufacturers . . . . ” In determining whether such a statutory cause of action must preserve the litigants’ right of access to a jury, this court has regularly applied a historical test: would this cause of action have been triable to a jury prior to the constitution of 1818? Id., 76, and cases there cited; see also Skinner v. Angliker, 211 Conn. 370, 375-78, 559 A.2d 701 (1989); Bishop v. Kelly, 206 Conn. [91]*91608, 618, 539 A.2d 108 (1988); Swanson v. Boschen, 143 Conn. 159, 164-66, 120 A.2d 546 (1956).
If Lemon Law II is accurately to be characterized, in law and in fact, as essentially a restatement of an enhanced cause of action for breach of express warranties, the plaintiffs would be correct in their contention that they cannot be deprived of their right to a trial by jury. “Whether a warranty claim is viewed as a contract action, a tort action, or a hybrid of the two . . . such a matter has always been triable to a jury.” Motor Vehicle Manufacturers Assn. I, supra, 77. If, however, the statute creates a new cause of action that is essentially an equitable claim for specific performance or rescission and restitution, then, as the defendants contend, there is no right to a jury trial for the enforcement or defense of Lemon Law II claims.5 We agree with the trial court that the record demonstrates the essentially equitable nature of Lemon Law II claims and hence we conclude that the plaintiffs have failed to prove their constitutional claim in this regard.
The trial court made the following findings relying on the records of 521 Lemon Law arbitration decisions rendered from October 1,1984, to September 30,1987. “Between 1985 and 1987, 75.58% of consumers requested refunds and 4.42% requested partial refunds. . . .

I
The plaintiffs’ first challenge to Lemon Law II asserts that the statutory arbitration procedures contained in § 42-181 (c) unconstitutionally deprive them of their right to a trial by jury, in violation of article first, § 19, of the Connecticut constitution.4 In Motor Vehicle Manufacturers Assn. I, supra, 68-69, we described Lemon Law II as a statute that “provides supplemental remedies of repair, replacement and refund to facilitate the enforcement of express warranties made by [automobile] manufacturers . . . . ” In determining whether such a statutory cause of action must preserve the litigants’ right of access to a jury, this court has regularly applied a historical test: would this cause of action have been triable to a jury prior to the constitution of 1818? Id., 76, and cases there cited; see also Skinner v. Angliker, 211 Conn. 370, 375-78, 559 A.2d 701 (1989); Bishop v. Kelly, 206 Conn. [91]*91608, 618, 539 A.2d 108 (1988); Swanson v. Boschen, 143 Conn. 159, 164-66, 120 A.2d 546 (1956).
If Lemon Law II is accurately to be characterized, in law and in fact, as essentially a restatement of an enhanced cause of action for breach of express warranties, the plaintiffs would be correct in their contention that they cannot be deprived of their right to a trial by jury. “Whether a warranty claim is viewed as a contract action, a tort action, or a hybrid of the two . . . such a matter has always been triable to a jury.” Motor Vehicle Manufacturers Assn. I, supra, 77. If, however, the statute creates a new cause of action that is essentially an equitable claim for specific performance or rescission and restitution, then, as the defendants contend, there is no right to a jury trial for the enforcement or defense of Lemon Law II claims.5 We agree with the trial court that the record demonstrates the essentially equitable nature of Lemon Law II claims and hence we conclude that the plaintiffs have failed to prove their constitutional claim in this regard.
The trial court made the following findings relying on the records of 521 Lemon Law arbitration decisions rendered from October 1,1984, to September 30,1987. “Between 1985 and 1987, 75.58% of consumers requested refunds and 4.42% requested partial refunds. . . . However, 99.61% of the consumers requested replacement (51.35%), repair (6.54%), incidental expenses (22.31%), consequential damages (2.30%), finance charges (3.46%) or other remedies (13.65%). . . . Furthermore, between 1985 and 1987, 39.54% of consumers received refunds and .19% received partial refunds. . . . However, 94.63% of consumers received replacement (7.87%), repair [92]*92(24.95%), incidental expenses (11.52%), finance charges (20.35%) or other remedies (29.94%).”6
These factual findings, which are not clearly erroneous, do not support the plaintiffs’ allegation that the nature of Lemon Law II claims and remedies is essentially legal rather than equitable. In the remand that we ordered in Motor Vehicle Manufacturers Assn. I, supra, we asked for precisely this kind of factual exploration of the scope of Lemon Law arbitrations. We agree with the plaintiffs that, to the extent that refunds are central to such proceedings, recharacterizing such refund claims as claims for rescission and restitution would not resolve the question of whether such claims are essentially legal or equitable, particularly when a legal action for revocation of acceptance, under §§ 2-608 and 2-715 of the Uniform Commercial Code; General Statutes §§ 42a-2-608 and 42a-2-715; covers much the same ground. Id., 79; see also Aubrey’s R. V. Center, Inc. v. Tandy Corporation, 46 Wash. App. 595, 600-601, 731 P.2d 1124 (1987). The trial court found, however, that, to a significant extent, consumers sought and received orders for replacement and repair designed to approximate the kind of specific relief that is characteristically equitable. “ ‘[W]hen legal and equitable issues are combined in a single action, whether the right to a jury trial attaches depends upon the relative importance of the two types of claims. . . .’’’Texaco, Inc. v. Golart, 206 Conn. 454, 458-59, 538 A.2d 1017 (1988); United States Trust Co. v. Bohart, 197 Conn. 34, 45, 495 A.2d 1034 (1985). Overall, the flexibility and range of Lemon Law remedies, as well as the statutory linkage of claims for repair and replacement with claims for a variety of monetary remedies, reflect a pattern that is more equitable than legal. Indeed, the very enactment of Lemon Law II arises [93]*93out of a legislative determination that legal remedies alone did not provide adequate relief for disappointed consumer purchasers of new motor vehicles. Cf. Conservation Commission v. Price, 193 Conn. 414, 429-30, 479 A.2d 187 (1984). We therefore conclude that the plaintiffs have not established that they were unconstitutionally deprived of their right to a jury trial.7
II
The plaintiffs’ second challenge to Lemon Law II focuses on the limited judicial review that the act affords to manufacturers who are disappointed by the outcome of arbitral decisions. Although consumers are entitled, at their discretion, to initiate de novo civil proceedings to prosecute their Lemon Law claims; General Statutes §§ 42-179 (i) and 42-181 (c); manufacturers may only appeal from arbitration decisions “in accordance with the provisions of sections 52-417, 52-418, 52-419 and 52-420.” General Statutes § 42-181 (c). The cross-referenced provisions, designed to govern appeals from awards in consensual arbitrations, require courts to defer to arbitral resolution of virtually all issues of law and fact, so long as the arbitral award conforms to the terms of the issues submitted for arbitration. Diamond Fertiliser & Chemical Corporation v. Commodities Trading International Corporation, 211 Conn. 541, 547, 560 A.2d 419 (1989); Wilson v. Security Ins. Group, 199 Conn. 618, 626-27, 509 A.2d 467 (1986). Because Lemon Law II’s arbitration procedures are compulsory for manufacturers,8 the [94]*94plaintiffs maintain that incorporation of consensual arbitration procedures violates the rights to judicial review that the Connecticut constitution guarantees to them. They claim first that the procedures violate the separation of powers provisions in that a legislatively created tribunal may resolve a legal dispute, traditionally an exclusive judicial function, without resort to review. Conn. Const., arts. II and V, § 1. Second, the plaintiffs claim that the provision that disallows them from pursuing judicial review of the arbitration panel’s decision violates their guaranteed right of access to courts. Conn. Const., art. I, § 10; see Ecker v. West Hartford, 205 Conn. 219, 234, 530 A.2d 1056 (1987). We agree with the plaintiffs.
This court has recently discussed the proper standard of judicial review of a compulsory arbitration award. Because of the fundamental difference between voluntary and compulsory arbitration, “a higher level of judicial review of an arbitration award is warranted where the arbitration is statutorily mandated.” American Universal Ins. Co. v. DelGreco, 205 Conn. 178, 188, 530 A.2d 171 (1987); Wilson v. Security Ins. Group, supra, 630; Carofano v. Bridgeport, 196 Conn. 623, 637-38, 495 A.2d 1011 (1985); see also Mount St. Mary’s Hospital v. Catherwood, 26 N.Y.2d 493, 500, 260 N.E.2d 508, 311 N.Y.S.2d 863 (1970). In DelGreco, we cited, with approval, case law from a number of jurisdictions holding that “compulsory arbitration statutes that effectively close the courts to the litigants by compelling them to resort to arbitrators for a final and binding determination are void as against public policy and are unconstitutional.” American Universal Ins. Co. v. DelGreco, supra, 188. The constitutional grounds relied upon in these other jurisdictions include the very [95]*95grounds pressed by the present plaintiffs: violation of a state’s constitutional separation of powers provisions, and violation of a state’s constitutional access to courts provision. Id., 189; see also Spillman v. United States Fidelity & Guaranty Co., 179 So. 2d 454, 455 (La. App. 1965); Macaluso v. Watson, 171 So. 2d 755, 758 (La. App. 1965); Biddeford v. Biddeford Teachers Assn., 304 A.2d 387, 402-403 (Me. 1973); Local 170, Transport Workers Union of America v. Circuit Judge, 322 Mich. 332, 347-48, 34 N.W.2d 71 (1948); Simon v. St. Elizabeth Medical Center, 3 Ohio Op. 3d 164, 167, 355 N.E.2d 903 (1976). In assessing the reach of these constitutional strictures, we concluded that compulsory arbitration passes constitutional muster “so long as fair procedures are provided by the legislature and ultimate judicial review is available. . . . Courts throughout the United States have uniformly upheld compulsory arbitration statutory schemes as against the constitutional challenges previously mentioned where de novo judicial review of the arbitrator’s award is available to either party.” (Emphasis in original.) American Universal Ins. Co. v. DelGreco, supra, 189.
Under § 42-181 (c), de novo judicial review is expressly afforded to consumers but not to manufacturers. The defendants justify this departure from the standard articulated in American Universal Ins. Co. v. DelGreco on the ground that the cross-reference in § 42-181 (c) to the judicial review standards of § 52-418, when properly construed, authorizes sufficiently broad judicial review to withstand the plaintiffs’ constitutional challenges. The defendants maintain that, in the context of compulsory arbitrations, § 52-418 permits judicial review closely resembling the scope of judicial review afforded to administrative proceedings. Pursuing that analogy, the defendants urge us to hold that § 52-418 authorizes a court, in an appeal from a compulsory arbitration award, to undertake a de novo review of ques[96]*96tions of law and a substantial evidence review of questions of fact. Because the proposed standard would permit judicial review that is broader than that traditionally available for § 52-418 review of voluntary arbitration awards, it would, according to the defendants, meet constitutional requirements while accommodating the Lemon Law’s purpose of avoiding costly litigation. The trial court relied on the defendants’ statutory construction argument in rejecting the plaintiffs’ constitutional claims.
The defendants’ proffered construction, although it has constitutional appeal,9 finds little direct support in the language of §§ 42-181 (c) or 52-418. We might nonetheless reach for a somewhat strained construction in the service of our acknowledged obligation to implement the legislature’s purpose in a manner that is both effective and constitutional, if it were reasonably clear that such a construction accorded with the legislature’s underlying intent. Compare McConnell v. Beverly Enterprises-Connecticut, Inc., 209 Conn. 692, 706, 553 A.2d 596 (1989), and Moscone v. Manson, 185 Conn. 124, 128, 440 A.2d 848 (1981), with Bishop v. Kelly, supra, 617, and French v. Amalgamated Local Union 376, 203 Conn. 624, 636-37, 526 A.2d 861 (1987). The legislative history is, however, to the contrary. During the earlier stages of this litigation, while arguing Motor Vehicle Manufacturers Assn. I in this court, the parties suggested the possible applicability, in the judicial review of Lemon Law arbitration decisions, of the substantial evidence rule that governs administrative appeals. The legislature promptly enacted Public Acts 1987, No. 87-522, § 1, which amends General Statutes § 4-166, the definitions section of the Uniform Administrative Procedure Act, to exclude “automobile [97]*97dispute settlement panels established pursuant to section 42-181” from the definition of “agency.” In effect, that amendment repudiated the suggestion that the administrative appeal standard of “substantial evidence” was intended to govern the judicial review of factfinding of Lemon Law II arbitrations. We considered the effect of similar legislative action in Circle Lanes of Fairfield, Inc. v. Fay, 195 Conn. 534, 539-41, 489 A.2d 363 (1985). There too the legislature had clarified its intent with regard to the scope of permissible administrative appeals during the pendency of judicial proceedings. We held that such a clarification bound the courts because of the legislature’s plenary authority to define the scope of administrative appeals. Id., 540. Applying that principle here leads us to conclude that the legislature intended to adopt a judicial review procedure for manufacturers contesting Lemon Law arbitration decisions that is substantially more limited than the review that a litigant may obtain after exhaustion of mandated administrative remedies. We agree with the plaintiffs that this limited review is constitutionally insufficient under the standards enunciated in American Universal Ins. Co. v. DelGreco, supra, 189.
Our conclusion about the unconstitutionality of the judicial review procedures incorporated in § 42-181 (c) finds additional support in the disparate access that the legislation affords to the various litigants who participate in Lemon Law II arbitrations. No question has been raised about the constitutionality of empowering the consumer to make the decision whether to invoke Lemon Law arbitration proceedings in the first instance. The difficulty arises because § 42-181 (c), in addition, permits the consumer, having invoked arbitration, to disregard an unfavorable award and to pursue a de novo civil action, while it limits the manufacturer to the record review contemplated by § 52-418. The parties have cited no authority, and we have dis[98]*98covered none, that the legislature, in fashioning rules for judicial review, may discriminate in such a fashion against the party whose participation in statutory arbitration proceedings is compulsory. We hold that such disparate treatment violates the plaintiffs’ constitutional right to a reasonable opportunity to have a remedy, “by due course of law,” in our courts. Conn. Const., art. I, § 10; see Ryszkiewicz v. New Britain, 193 Conn. 589, 597-600, 479 A.2d 793 (1984).
Ill
The plaintiffs’ final claim is that the provision of § 42-181 (b) requiring a manufacturer to pay a $250 filing fee to defend against a consumer’s complaint violates their constitutional guarantees of due process and equal protection of the laws.10 We conclude that the fee requirement does not violate the plaintiffs’ constitutional rights.
The plaintiffs argue that their having to pay an access fee violates their fundamental right to present a defense.11 If the plaintiffs were correct in their premise that the access fee deprives them of a judicial hearing, the statutory fee might have to pass a strict scrutiny test. Boddie v. Connecticut, 401 U.S. 371, 380, 91 S. Ct. 780, 28 L. Ed. 2d 113 (1971), upon which the plaintiffs rely, held that such an access fee “may offend [99]*99due process [when] it operates to foreclose a particular party’s opportunity to be heard.” We are, however, unpersuaded of the plaintiffs’ premise that the statute imposes such draconian consequences. In conjunction with the $250 filing fee, General Statutes § 42-18512 provides for a waiver of the filing fee upon proof of economic hardship. Thus, unlike the appellants in Boddie, if one of the plaintiffs somehow could not afford the filing fee, the legislature has provided for the vindication of that party’s right to be heard.
We are equally unpersuaded of the plaintiffs’ alternate argument that the $250 filing fee requirement deprives them of equal protection of the laws because it treats them differently from other civil defendants, who need not pay filing fees to defend themselves from suit. The equal protection clause mandates like treatment for all those similarly situated. Darak v. Darak, 210 Conn. 462, 473, 556 A.2d 145 (1989); Barde v. Board of Trustees, 207 Conn. 59, 65, 539 A.2d 1000 (1988). In determining the validity of disparities in personal treatment, courts ordinarily invoke the rational basis test, which is especially applicable to the review of economic and social legislation. See United States v. Kras, 409 U.S. 434, 446, 93 S. Ct. 631, 34 L. Ed. 2d 626 (1973); Chrysler Corporation v. Texas Motor Vehicle Commission, 755 F.2d 1192, 1202-1203 (5th Cir. 1985); Zapata v. Burns, 207 Conn. 496, 506-507, 542 A.2d 700 (1988). We conclude that there exists a [100]*100rational nexus between the legislature’s goal of creating a fiscally independent arbitration mechanism for automobile consumers and the requirement that manufacturers pay a filing fee.13 The plaintiffs have, accordingly, failed to sustain their heavy burden of proving that this statutory provision is unconstitutional beyond a reasonable doubt. Zapata v. Burns, supra, 508; Peck v. Jacquemin, 196 Conn. 53, 64-65, 491 A.2d 1043 (1985).
There is error, the judgment is set aside and the case is remanded to the trial court with direction to render judgment for the plaintiffs.
In this opinion the other justices concurred.
