The primary issue in this products liability case is whether ORS 30.905,1 the products liability statute of ultimate repose, violates either the Oregon Constitution or the Seventh or Fourteenth Amendments to the United States Constitution. A secondary issue concerns whether plaintiffs’ complaint alleges a negligent, continuing failure on the part of the manufacturer to warn of the product’s defective and dangerous condition. If the pleadings adequately allege such a theory, a question arises whether the time limit imposed by ORS 30.905(1) can be avoided by pleading a negligent continuing failure to warn consumers of such dangers. We hold that ORS 30.905 is constitutional under both constitutions. We further hold that plaintiffs allegations are insufficient to raise a theory of negligent, continuing failure to warn of a dangerous or defective product.
FACTS
On April 23, 1986, 15-year-old Scott Sealey, the plaintiff, was a passenger in a 1975 Toyota Landcruiser. The driver, defendant Erik James Hicks, also a minor, lost control of the vehicle. The vehicle rolled over and its roof came off. Plaintiff was seriously injured and is now a quadriplegic.
Plaintiff, acting through his guardian ad litem, filed his original complaint on August 27, 1986. The defendants were Hicks, Toyota Motor Distributors, and Toyota Motor Corporation (TMC). TMC moved for summary judgment, claiming that the action was time barred by ORS 30.905(1) because the vehicle was originally sold in May of 1975 and the accident occurred more than eight years later. The trial court agreed and granted summary judgment. Finding no reason for *391delay, the court entered judgment for TMC and against plaintiff pursuant to ORCP 67 B.2
Plaintiff appealed, contending that, insofar as ORS 30.905(1) bars a claim before the injury upon which it is based even occurs, the statute is unconstitutional. Plaintiff further contended that, even if ORS 30.905(1) is constitutional, he also has alleged ordinary post-purchase negligence, governed by the general torts statutes of limitation and repose, ORS 12.110(1)3 and 12.115, and his complaint was timely under those statutes.4
The Court of Appeals upheld the constitutionality of ORS 30.905(1).5 Sealey v. Hicks, 95 Or App 182, 768 P2d 428 (1989). The Court of Appeals further ruled that plaintiff had not alleged a continuing failure to warn and, even if he had, the definition of “product liability civil action” provided in ORS 30.9006 included within its limitation any failure to warn *392concerning a defective product. We allowed plaintiffs resulting petition for review to address the important issues involved.
THE STATUTE’S MEANING
The products liability statute of repose, ORS 30.905(1), states that it applies “except as provided in subsection (2) of this section.” This language could be read to make the time limit in ORS 30.905(1) subordinate to the time limit in ORS 30.905(2). If it were so read, the fact that plaintiff commenced this action less than two years after the accident would make the action timely under ORS 30.905(2). This interpretation, however, renders ORS 30.905(1) a virtual nullity — an action brought 10, 20, or even 30 years after a product was “first purchased for use or consumption” would still be timely so long as it was brought within two years of the date of the “death, injury or damage complained of.” The legislature cannot have intended to enact a provision that would have no legal effect.
A brief look at the legislative history reveals the legislature’s intent and a rational statutory structure. ORS 30.905(2) is a statute of limitation. Anyone injured by a defective product has two years from the date of the death, injury, or damage complained of to commence a civil action. ORS 30.905(1), on the other hand, is a statute of repose. The legislature has determined that an injury occurring more than eight years after a defective product first entered the stream of commerce is not legally cognizable. See Minutes, House Judiciary Committee, May 16, 1977, pp 10-12. Plaintiff here filed within two years of his injury, but his injury did not occur within eight years of the date the vehicle first was purchased. Subsection (1) of ORS 30.905 is the applicable subsection. Plaintiffs case therefore was properly ended by summary judgment, unless some constitutional provision, state or *393federal, forbids the enactment or application of ORS 30.905(1). We turn to that issue.
THE STATUTE’S CONSTITUTIONALITY
Plaintiff attacks the constitutionality of ORS 30.905(1) on five separate bases, three under the Oregon Constitution and two under the Federal Constitution. As is our normal practice, we consider the three state constitutional challenges before moving on to the federal issues. See, e.g., State v. Kennedy, 295 Or 260, 666 P2d 1316 (1983).
1. Article I, Section 10
Article I, section 10, of the Oregon Constitution provides:
“No court shall be secret, but justice shall be administered, openly and without purchase, completely and without delay, and every man shall have remedy by due course of law for injury done him and his person, property or reputation.”
Plaintiff contends that ORS 30.905(1) violates this section because it bars his claim before the claim ever accrues, thereby denying him a “remedy by due course of law for [an] injury done him and his person.” Plaintiff is particularly aggrieved because the statute of repose eliminates his remedy even before he has suffered an injury. This is true. ORS 30.905(1) does bar plaintiffs claim and deny him a remedy for what would otherwise be a legally cognizable injury. However, ORS 30.905(1) is nonetheless constitutional.
This court already has considered and upheld the constitutionality of another statute of ultimate repose under similar circumstances. In Josephs v. Burns & Bear, 260 Or 493, 491 P2d 203 (1971), the plaintiffs were the owners of a building whose roof collapsed more than 10 years after its construction. Plaintiffs alleged that the collapse resulted from the defendant’s negligent construction of the building.
At that time ORS 12.115(1) provided:
“In no event shall any action for negligent injury to person or property of another be commenced more than 10 years from the date of the act or omission complained of.”
The trial court sustained the defendant’s demurrer on the *394basis that the statute of limitations had run prior to the commencement of the action.7 This court affirmed the trial court’s ruling despite the plaintiffs’ contention “that a statute which purports to extinguish a remedy before the legally protected right becomes actionable is unconstitutionable because it contravenes Article I, section 10, of the Oregon Constitution * * *.” Id. at 502. We held:
“Assuming that the effect of ORS 12.115(1) is to abolish causes of action in tort where the damage does not result within ten years after the negligent acts or omissions complained of, we see nothing unconstitutional in so doing. * * *
******
“It has always been considered a proper function of legislatures to limit the availability of causes of action by the use of statutes of limitation so long as it is done for the purpose of protecting a recognized public interest. It is in the interest of the public that there be a definite end to the possibility of future litigation resulting from past actions. It is a permissible constitutional legislative function to balance the possibility of outlawing legitimate claims against the public need that at some definite time there be an end to potential litigation.”
The reasoning of Josephs is equally applicable to civil product liability actions.8 The legitimate legislative purposes behind ORS 12.115(1) also support ORS 30.905(1).
Article I, section 10, does not apply to a situation like the present one. The legislature has the authority to determine what constitutes a legally cognizable injury. It has chosen to declare that injuries resulting from defective products are not legally cognizable if they occur more “than 8 years after the date on which the product was first purchased for use *395or consumption.” In making this determination, the legislature has not deprived this plaintiff of a preexisting remedy for his injury.9
Plaintiff relies heavily on Heath v. Sears, Roebuck & Co., 464 A2d 288 (NH 1983). In Heath, the Supreme Court of New Hampshire struck down the entire New Hampshire products liability statutory scheme as unconstitutional under the New Hampshire state constitution. Obviously, Heath has no direct authority here, but we are always open to persuasive analysis from any source. However, we find little helpful assistance in the Heath opinion.
Heath rests on a similar state constitution remedies clause. Part one, article fourteen of the New Hampshire Constitution provides:
“Every subject of this state is entitled to a certain remedy, by having recourse to the laws, for all injuries he may receive in his person, property, or character; to obtain right and justice freely, without being obligated to purchase it; completely and without any denial; promptly, and without delay; conformably to the laws.”
The New Hampshire Supreme Court views this clause as a substantive guarantee that the state courts will provide a remedy to every citizen for every injury. Based on this provision, the court determined that “although not a fundamental right, ‘the right to recover for personal injuries is * * * an important substantive right.’ ” Id. at 294. An attempt to alter or eliminate this right was subject to attack under the state’s equal protection clause wherein “classifications * * * were required to be ‘reasonable’ and to ‘rest upon some ground of difference having a fair and substantial relation to the object of the legislation.’ ” Id. at 294-95. The court reviewed various provisions of the product liability law and found that many of the provisions were unreasonable or not “substantially related to a legitimate legislative object.” Id. at 296. The 12-year statute of repose was found unreasonable because it could deprive persons of a remedy before their claim had accrued and because it was, in that court’s view, unrelated to *396the underlying purpose of holding down insurance rates, primarily because “the crisis in products liability insurance had abated nationwide independent of [this law].”10 Id.
Such statements reflect a fundamental difference between the powers and duties of the Supreme Court of New Hampshire and of this court. There is no “substantive due process” clause in our constitution. We are not empowered to strike down a duly enacted law simply because we believe it is unwise, unnecessary, or unsuccessful. Apparently, the Supreme Court of New Hampshire is so empowered. Lacking such a power, we are in no position to strike down ORS 30.905(1) under a Heath approach.
2. Article I, Section 17
Article I, section 17, of the Oregon Constitution provides:
“In all civil cases the right of Trial by Jury shall remain inviolate.”
Plaintiff argues that, “[b]y denying this minor plaintiff any access to the Oregon Courts, ORS 30.905 has deprived the minor plaintiff [of] the right to have his claim heard by a jury.” This contention is without merit. ORS 30.905(1) terminates product liability claims for all persons no matter what their age. Plaintiff is not deprived of any right or privilege because of his age. Section 17 is designed to guarantee a jury trial when a right to a trial exists in a civil action.11 It is not an independent guarantee of the existence of a cognizable claim.
3. Article I, Section 20
Plaintiff contends that ORS 30.905 violates Article I, section 20, of the Oregon Constitution:
“No law shall be passed granting to any citizen or class of citizens privileges, or immunities, which, upon the same terms, shall not equally belong to all citizens.”
*397The question is whether plaintiff is a member of a class, some of whom have been denied a privilege or immunity granted to others in the same class, or whether the manufacturers and sellers of products have been granted a privilege or immunity not available equally to others in the same class. See State v. Clark, 291 Or 231, 237-40, 630 P2d 810 (1981).
In evaluating whether a class exists under Article I, section 20, we must first determine whether the class “is created by the challenged law itself’ or “by virtue of characteristics * * * apart from the law in question.” State v. Clark, supra, 291 Or at 240. Classes of the first type are entitled to no special protection and, in fact, are not even considered to be classes for the purposes of Article I, section 20. See, e.g., Hale v. Port of Portland, 308 Or 508, 783 P2d 506 (1989); Cole v. Dept. of Rev., 294 Or 188, 191-92, 655 P2d 171 (1982); State v. Freeland, 295 Or 367, 374-75, 667 P2d 509 (1983); Norwest v. Presbyterian Intercommunity Hosp., 293 Or 543, 567-68, 652 P2d 318 (1982); State v. Clark, supra, 291 Or at 242-43.
There are three classes alleged to be at issue in this case:
(1) Persons injured by products more than eight years after their initial sale, contrasted with persons injured by products sold more recently;
(2) Potential tortfeasors who injure their victims with eight-year-old manufactured products, contrasted with tortfeasors who injure their victims in other ways; and
(3) Persons injured by products, contrasted with those persons injured by other causes.
The first two classes are clearly classes “created by the challenged law itself.” Any statute of repose, by setting a time limit beyond which the legislature declines to recognize the existence of a legal injury, will divide tortfeasors and their victims into classes based upon those time limits. However, such a decision is within the purview of the legislature.
The third class does exist apart from the statute. Whether an individual is injured by a manufactured product or in some other fashion is not dependent upon the terms of the statute. Nevertheless, the legislature has the authority to decide, for example, that increases in insurance rates or other *398costs associated with litigation warrant legislation to limit the liability of manufacturers in order to ensure the continued availability of manufactured goods at a reasonable cost. If the legislature attempted to deny a recovery to specific individuals, or to permit the courts to deny such a recovery to arbitrarily chosen members of the same class, Article I, section 20, might be violated. But that is not the case here.12 See Hale v. Port of Portland, supra; State v. Freeland, supra; State v. Clark, supra.
4.Seventh Amendment
Plaintiff contends that ORS 30.905(1) violates his right to a jury trial under the Seventh Amendment in the United States Constitution. The Seventh Amendment right to a jury trial does not apply to the states. See, e.g., Dohany v. Rogers, 281 US 362, 50 S Ct 299, 74 L Ed 904 (1930).
FOURTEENTH AMENDMENT
Plaintiff claims that ORS 30.905 violates the Equal Protection Clause of the Fourteenth Amendment to the United States Constitution. We disagree. In a federal equal protection analysis, the first step is to ascertain the level of scrutiny to be applied to the governmental action.
The appropriate level of review in this case is the “rational basis test.” Under this test, a court simply asks whether “a classification bears a rational relationship to an end of government which is not prohibited by the Constitution.” If it does bear such a relationship, the matter is at an end. 2 Rotunda, Nowak & Young, Treatise on Constitutional Law: Substance and Procedure 324 (1986). Clearly, the classifications made by ORS 30.905(1) do bear such a relationship to legitimate legislative ends, among them avoiding the necessity of trying stale claims. This argument is not well taken.
*399CONTINUING FAILURE TO WARN
Plaintiffs final argument is that his complaint alleged a negligent continuing failure by TMC to warn of the Landcruiser’s defects. If plaintiff is correct, that portion of his complaint would be governed by the two-year negligence statute of limitation, ORS 12.110, and summary judgment would not have been appropriate. TMC responded, and the Court of Appeals agreed,13 that plaintiff alleged no continuing failure to warn. We agree that plaintiffs complaint did not adequately raise the question of a continuing failure to warn.
The closest plaintiffs complaint came to such allegations were the following allegations:
“[A] proximate cause and/or enhancement of plaintiffs personal injuries was the negligence of defendant [TMC] in one or more of the following particulars:
* * * *
“4. In failing to give adequate warning of the vehicle’s dangerous propensity to roll over at low speeds.”
The only reasonable reading of these allegations is that they refer to an initial failure to warn prior to the first sale of the vehicle; they cannot also be read to include a failure to warn at some later date after the product’s defect was discovered. While ORCP 12 A directs that “[a]ll pleadings shall be liberally construed with a view of substantial justice between the parties,” we would have to rewrite these pleadings, not construe them, to make out a claim of negligent continued failure to warn. The Court of Appeals correctly concluded that this theory had not been adequately pleaded.14
The decision of the Court of Appeals and the judgment of the circuit court are affirmed.
ORS 30.905 provides:
“(1) Notwithstanding ORS 12.115 or 12.140 and except as provided in subsection (2) of this section and ORS 30.907, a product liability civil action shall be commenced not later than eight years after the date on which the product was first purchased for use or consumption.
“(2) Except as provided in ORS 30.907, a product liability civil action shall be commenced not later than two years after the date on which the death, injury or damage complained of occurs.”
ORCP 67 B provides:
“When more then one claim for relief is presented in an action, whether as a claim, counterclaim, cross-claim, or third party claim, or when multiple parties are involved, the court may direct the entry of a final judgment as to one or more but fewer than all of the claims or parties only upon an express determination that there is no just reason for delay and upon an express direction for entry of judgment. In the absence of such determination and direction, any order or other form of decision, however designated, which adjudicates fewer than all the claims or the rights and liabilities of fewer than all the parties shall not terminate the action as to any of the claims or parties, and the order or other form of decision is subject to revision at any time before the entry of judgment adjudicating all the claims and rights and liabilities of all the parties.”
ORS 12.110(1) provides in pertinent part:
“An action for assault, battery, false imprisonment, or for any other injury to the person or rights of another, not arising on contract, and not especially enumerated in this chapter, shall be commenced within two years * *
ORS 12.115 provides:
“(1) In no event shall any action for negligent injury to person or property of another be commenced more than 10 years from the date of the act or omission complained of.
“(2) Nothing in this section shall be construed to extend any period of limitation otherwise established by law, including but not limited to the limitations established by ORS 12.110.”
TMC also claimed that an earlier, favorable resolution of this same claim against co-defendant Toyota Motor Distributors was the law of the case and absolved it as well. The Court of Appeals rejected that contention. The issue was not raised before us and we do not consider it.
ORS 30.900 provides:
“As used in ORS 30.900 to 30.920, ‘product liability civil action’ means a civil *392action brought against a manufacturer, distributor, seller or lessor of a product for damages for personal injury, death or property damage arising out of:
“(1) Any design, inspection, testing, manufacturing or other defect in a product;
“(2) Any failure to warn regarding a product; or
“(3) Any failure to properly instruct in the use of a product.”
Although the Josephs court referred to ORS 12.115(1) as a “statute of limitation,” we prefer to view it in this context as a “statute of ultimate repose.” A “statute of limitation” limits the time a party has to initiate an action once a claim has accrued. A “statute of ultimate repose,” on the other hand, provides a deadline for the initiation of an action whether or not the injury has been discovered or has even occurred.
In fact, prior to the enactment of ORS 30.905(1) we held in Johnson v. Star Machinery Co., 270 Or 694, 530 P2d 53 (1974), that the general torts statute of repose, ORS 12.115(1), also applied to strict product liability actions.
Prior to the enactment of ORS 30.905, this plaintiff would have been barred by the general ten-year ultimate statute of repose, ORS 12.115(1), which we applied to product liability actions in Johnson v. Star Machinery Company, supra n 9.
There apparently was some support in the record for this conclusion in the form of a report by a New Hampshire Legislative Commission to Study Product Injury Reparations.
By “civil action” we mean what was once called an action at law. There is no right to a jury trial in equity. Phillips v. Johnson, 266 Or 544, 549, 514 P2d 1337 (1973).
If, for example, the legislature established a statute of repose that applied only to this defendant, to injured persons with facial hair, or to persons bom in Canada, we doubtless would strike down the limitation as a violation of Article I, section 20.
Sealey v. Hicks, 95 Or App 182, 185, 768 P2d 428 (1989).
We express no opinion as to whether a properly pleaded continuing failure to warn would actually state a cause of action independent of the statutory product liability claim.
