In Raymonde Aleta Slater v. John Robert Blackwood, the Supreme Court of California addressed the retroactive application of its prior ruling declaring the guest statute unconstitutional. The plaintiff, a minor injured in a 1969 car accident while a guest in the defendant's vehicle, initially filed a damages claim in 1970 under California’s guest statute, which limited recovery to cases of intoxication or wilful misconduct. The trial court granted a nonsuit in favor of the defendants based on the statute, leading to a judgment against the plaintiff, which was affirmed by the Court of Appeal.

In 1973, after the court's decision in Brown v. Merlo deemed the guest statute unconstitutional as applied to nonowner guests, the plaintiff filed a new complaint based on the same accident, seeking recovery on a negligence theory. The defendants argued that the original judgment barred this new action under the doctrine of res judicata. The trial court agreed and sustained the demurrers without leave to amend.

On appeal, the plaintiff contended that res judicata did not apply because the second complaint represented a distinct cause of action, that the court should have rejected the res judicata defense in the interest of justice, and that defendants were estopped from claiming res judicata due to their prior actions. The court rejected these arguments, affirming that a valid final judgment on the merits serves as a complete bar to further litigation on the same cause of action, emphasizing California's 'primary rights' theory, which maintains that the invasion of one primary right gives rise to a single cause of action. Thus, the court concluded that the plaintiff's right to be free from personal injury constituted the same primary right in both actions, affirming the judgment against her.

One personal injury resulting from a wrongful act constitutes a single cause of action, regardless of the number of legal theories presented. The harm suffered is the basis for the cause of action, not the specific legal theory used. Consequently, a judgment for the defendant bars any subsequent actions by the plaintiff related to the same injury, even if a different legal ground is claimed. The term "cause of action" can refer to different counts asserting the same underlying claim.

The plaintiff’s argument that multiple causes of action exist due to language in previous cases is dismissed, as such terminology is often used interchangeably. The court also addresses the possibility of applying res judicata, noting it may be disregarded in cases of manifest injustice. However, the court questions the validity of this doctrine and clarifies that it does not apply when the basis for its invocation is a change in law post-judgment. Previous case law supports this view, as illustrated by an example where a plaintiff sought to vacate a judgment following a significant change in legal interpretation regarding governmental immunity.

The appellate court reversed the trial court's decision by affirming the applicability of res judicata, emphasizing that changes in case law do not justify relitigating previously settled matters. The court cited the principle that a prior judgment, even if based on an erroneous understanding of the law, remains binding to ensure the finality of judgments and maintain judicial order. It referenced cases such as Zeppi and Bank of America, which support the notion that judgments based on later invalidated statutes are still res judicata in subsequent suits. The court acknowledged the hardships caused by legal changes but stated that public policy necessitates an end to litigation, as reopening cases could undermine the finality of judicial decisions.

The court rejected the plaintiff's argument that defendants were estopped from asserting res judicata due to their motion for nonsuit in the earlier action. It clarified that the defendants had not taken inconsistent positions in their litigations and had consistently maintained that the plaintiff's claim was not legally viable under the law at the time of the original filing. Thus, the court concluded that allowing the plaintiff's theories would disrupt the stability of judgments and affirmed the trial court's ruling sustaining the defendants' demurrer based on res judicata. The judgment was ultimately upheld, with the court denying the appellant's petition for rehearing.
