Statute of Repose:  Although a twelve (12) year statute of repose is on the books for product liability actions, the statute was declared unconstitutional in Hazine v. Montgomery Elevator, 861 P.2d 625 (Ariz. 1993) and has not been enforced since.

Accrual Rule:  Statute begins to run when the injured party discovers, or through reasonable diligence and intelligence should have discovered, the facts that form the basis of a cause of action. In most cases, this is the injury and a causal link. (Discovery Rule Based)
