Plaintiffs appeal from the district court’s grant of a motion for judgment on the pleadings. The court held that the two-year statute of limitations in Ariz.Rev.Stat. § 12-542(2) barred the plaintiffs’ wrongful death action. We reverse and remand.
I. BACKGROUND
The plaintiffs’ decedent, James R. Davis, died from cancer of the kidney on October 9, 1976. The plaintiffs, Davis’ wife and two daughters, asserted that the cancer was caused by exposure to dioxin, a chemical manufactured by the defendant, Dow Chemical Corporation (“Dow”). Davis had been exposed to dioxin by using a garden herbicide produced by Dow. The plaintiffs contended that at the time of Davis’ death they did not know of, and could not reasonably have known of, the link between dioxin and cancer of the kidney. They alleged that they discovered, and “in the exercise of reasonable diligence should have discovered,” the link between dioxin and cancer only in April 1984, when certain facts about dioxin became public. On May 7, 1985, the plaintiffs brought suit for wrongful death pursuant to Ariz.Rev.Stat.Ann. §§ 12-611 to -613 (1982).
The plaintiffs filed this action almost nine years after Davis’ death but less than two years after the alleged date of discovery of the link between Dow’s chemical and Davis’ death. Dow moved for judgment on the pleadings pursuant to Fed.R. Civ.P. 12(c), contending that Ariz.Rev.Stat. Ann. § 12-542(2) barred any action for wrongful death not prosecuted within two years of the victim’s death.

The district court, with the consent of the parties, certified two questions of law to the Arizona Supreme Court: (1) whether the date of discovery rule in determining accrual dates for a statute of limitations applies to the wrongful death statute, and (2) whether the wrongful death statute of limitations violates article 18, section 6 of the Arizona Constitution

by barring an action before it reasonably could be discovered. The Arizona Supreme Court declined jurisdiction, stating that it “appealed] that
Kenyon v. Hammer,
The district court subsequently decided that the “reasoning of Kenyon does not extend to an action for wrongful death,” concluded that the plaintiffs’ action was time-barred, and granted Dow’s motion for judgment on the pleadings. On appeal, the plaintiffs primarily argue (1) that the discovery rule applies to the wrongful death *233 statute of limitations, and (2) in the alternative, that the statute of limitations, as applied by the district court in this case, violates article 18, section 6 of the Arizona Constitution, as well as the state equal protection clause in article 2, section 13. The plaintiffs further contend that Dow’s alleged fraudulent concealment of information concerning dioxin should toll the statute of limitations.
II. DISCUSSION
This court reviews de novo a district court’s interpretation of state law.
MWS Wire Indus., Inc. v. California Fine Wire Co.,
A. Judicial Construction of the Discovery Rule
Arizona’s statute of limitations governing tort actions provides generally that actions must be commenced and prosecuted “within two years after the cause of action accrues.” Ariz.Rev.Stat.Ann. § 12-542 (Supp.1986). This statute does not define the point at which most tort actions accrue. Arizona courts have adopted the discovery rule for these tort actions and held that such an action accrues when the plaintiff knew or by the exercise of reasonable diligence should have known that a claim exists.
Kenyon v. Hammer,
The plaintiffs contend that the discovery rule should similarly apply to the wrongful death statute of limitations.
Kenyon
does not support this contention. The court in
Kenyon
refused to apply the discovery rule to the state’s medical malpractice statute of limitations, which specified that a cause of action for medical malpractice accrues as of “the date of injury.” Ariz.Rev.Stat. Ann. § 12-564(A) (1982) (repealed 1985). The court observed that this statute, along with the wrongful death statute of limitations, is “the only tort statute which contains a legislative definition of the term ‘accrues.’ ”
Kenyon,
The wrongful death statute of limitations also defines a particular time of accrual: “the death of the party injured.” Thus, like the statute in
Kenyon,
it is not amenable to judicial construction of the word “accrues.” The district court correctly held that the discovery rule does not, as a matter of judicial construction, apply to the wrongful death statute in § 12-542(2).
See Anson v. American Motors Corp.,
No. 1-CA-CIV-7625, slip op. at 9-10 (Ariz.Ct. App. Mar. 31, 1987);
Gomez v. Leverton,
*234 B. The Constitutionality of the Statute of Limitations
In
Kenyon,
the Arizona Supreme Court held that the right to bring an action for bodily injury is a fundamental right under the Arizona Constitution.
Id.
at 83,
We believe that either rationale supports a similar conclusion in this case. In An-son, a decision of the Arizona Court of Appeals rendered after the district court’s decision in this case, the court held that the right to bring a wrongful death action is a fundamental right under article 18, section 6 and article 2, section 31 4 of the Arizona Constitution. Anson, slip op. at 9-10. The court reasoned that the “special burden” placed on a group of tort claimants by the denial of the discovery rule in wrongful death actions was not rationally related to an important state interest, much less justifiable as serving a compelling state interest. Id. at 10-14. The court also held that the two-year limitation ran afoul of article 18, section 6 by abrogating a cause of action before it reasonably could have been discovered. Id. at 15. The Anson court therefore applied the discovery rule to the wrongful death statute of limitations in order to prevent the statute from violating the Arizona Constitution. Although a decision of an intermediate state appellate court is not binding on us, we find it to be persuasive authority. 5
Dow argues that § 12-542(2) does not involve a fundamental right as in
Kenyon,
but a right of statutory creation that is not subject to the protections of the Arizona Constitution. It cites an observation in
Halenar v. Superior Court,
We decline to rely on the implications of the statements in
Halenar
and
Schoenrock
for several reasons. First, in
Summerfield v. Superior Court,
The creation of rights by tort theory is primarily a matter of state law; the state may create such rights, provide defenses to them and regulate them, except that once szwh rights have been created and vested the state may not arbitrarily abrogate them.
Kenyon,
Dow also argues that § 12-542(2) is constitutional because it merely limits or regulates a cause of action, but does not abrogate it. This position is clearly untenable. As stated in Kenyon, "any statute which bars a cause of action before it could legitimately be brought abrogates rather than limits the cause of action and offends Article 18, § 6 of the Arizona Constitution." Id. at 75,
Therefore, as in Kenyon, invocation of the discovery rule is necessary to save the statute from constitutional infirmity. We hold that, under Arizona law, causes of action for wrongful death accrue at the death of the injured person unless application of the two-year period would abrogate the cause of action before it reasonably could be discovered. In those cases, Arizona courts "shall follow the discovery rule." Kenyon,
CONCLUSION
For the reasons given above, we reverse the decision granting Dow's motion for judgment on the pleadings. On remand, the district court should permit the parties to offer evidence on whether the plaintiffs knew or by the exercise of reasonable diligence should have known of the link between dioxin and cancer of the kidney, and whether Dow fraudulently concealed such information, as the plaintiffs contend. See id. at 2, 15-24.
REVERSED AND REMANDED.
Notes
. The statute provides in pertinent part:
[TJhere shall be commenced and prosecuted within two years after the cause of action accrues, and not afterward, the following actions:
2. For injuries done to the person of another when death ensues from such injuries, which action shall be considered as accruing at the death of the party injured.
Ariz.Rev.Stat.Ann. § 12-542 (Supp.1986).
. This provision states:
The right of action to recover damages for injuries shall never be abrogated, and the amount recovered shall not be subject to any statutory limitation.
Ariz. Const, art. 18, § 6.
.
Kenyon
involved claims for medical malpractice brought by a husband and wife for injury done to the wife and to their baby. Although the parents had filed a claim for wrongful death because the baby was stillborn, the court ruled that the medical malpractice statute of limitations superseded the wrongful death statute of limitations and that the wrongful death statute would not apply.
Kenyon v. Hammer,
. This provision states:
No law shall be enacted in this State limiting the amount of damages to be recovered for causing the death or injury of any person.
Ariz. Const, art. 2, § 31.
. At oral argument, counsel for Dow stated that a motion for reconsideration had been filed in Anson, based partly on the nonsubstantive ground that the Anson court should not have reached the constitutional issues because they were raised only in a reply brief. We note that, should Anson be withdrawn on that ground, we would reach the same conclusion. Anson supports, but is not necessary to, our holding, which relies principally on our understanding of Kenyon.
