Berk v. Choy

Background

Harold Berk sued a hospital and a doctor after treatment for a broken ankle in Delaware. Delaware law requires a medical professional’s “affidavit of merit” to accompany a malpractice complaint or the clerk must refuse to file it. Berk filed in federal court under diversity, failed to supply the affidavit, the District Court dismissed, and the Third Circuit affirmed.

Reasoning

The Court asked whether a Federal Rule of Civil Procedure answers the same question as Delaware’s affidavit law. It held that Rule 8, which requires only a short, plain statement of a claim, governs the information a plaintiff must give at the start of a federal case. Because Rule 8—backed by Rule 12’s limits on considering materials outside the pleadings and by the Rules Enabling Act—answers the same question and is a valid procedural rule, it displaces Delaware’s §6853. The Court also rejected arguments that Rule 11 or creative reinterpretations of §6853 preserve the state rule in federal court. The Supreme Court reversed and remanded.

Real world impact

The decision means federal courts sitting in diversity cannot enforce Delaware’s affidavit filing rule. Plaintiffs can proceed in federal court without the state affidavit and defendants must use tools in the Federal Rules, like motions for summary judgment, to challenge claims. The ruling applies when a Federal Rule directly conflicts with a state filing requirement, and the case returns to lower courts for further proceedings.

Dissents or concurrances

Justice Jackson agreed the affidavit law cannot apply but emphasized conflicts with Federal Rules 3 and 12 rather than Rule 8, noting the affidavit functions as a filing precondition or a matter outside the pleadings.
