What are the factors that determine whether a plaintiff has standing in a claim for emotional distress arising from the abuse of a deceased relative?

The source of a plaintiff's knowledge of misconduct which cannot be readily observed, and the time at which the knowledge was acquired, do not otherwise affect the plaintiff's standing to seek relief except insofar as the statute of limitations may bar the action. These factors instead go to the reasonableness of a plaintiff's claim to have suffered severe emotional distress and thus present issues for the trier of fact. We cannot say as a matter of law, as defendants would have us do, that belated discovery of mistreatment of the remains of a close relative cannot cause severe emotional distress. That suits may be filed by some persons as to whom the degree of suffering claimed is unreasonable is not a basis for denying relief to all. (Dillon v. Legg, supra, 68 Cal.2d 728, 736-739, 69 Cal.Rptr. 72, 441 P.2d 912.)
