A doctrinal conflict that arises when a federal court sitting in diversity must decide whether to apply a federal rule or a state rule on a given issue. The analysis first checks for a valid Federal Rule of Civil Procedure on point. When none exists the court weighs state substantive policies against federal institutional interests or applies the forum-shopping deterrence test.
Ethan Evans sued Eclipse Manufacturing in federal court under diversity jurisdiction after a workplace injury. Eclipse sought to invoke a state rule channeling contribution issues to an administrative tribunal. A valid Federal Rule of Civil Procedure addressed jury trials on those issues. The court applied the federal rule because it was on point and valid under the Rules Enabling Act.
Eva Espinosa filed a diversity action against Elemental Pharmaceuticals for asbestos-related harm. The state had enacted a statute that extinguished the cause of action after a fixed period. Federal practice would have allowed the suit to proceed. The court dismissed the claim because the state rule determined whether recovery was possible at all.

In a civil action where state law supplies the rule of decision the effect of a state presumption is itself governed by state law. The federal court must give the presumption the same force it would have in state court.

A federal court sitting in diversity must respect the bar. The state rule determines whether the plaintiff can recover at all and therefore controls the outcome.
