Berk v. Choy

607 U.S. ___ (2026) · Supreme Court of the United States · January 20, 2026 · No. 24-440

Summary

The Supreme Court held that Delaware’s medical-malpractice affidavit-of-merit requirement does not apply in federal court because it conflicts with the Federal Rules of Civil Procedure, particularly Rule 8. The Court reversed the Third Circuit and remanded, concluding that Rule 8 is valid under the Rules Enabling Act and displaces the contrary state requirement.

Questions Presented

  1. Whether Delaware's medical-malpractice affidavit-of-merit requirement applies in federal court when it conflicts with the Federal Rules of Civil Procedure.
  2. Whether Federal Rule of Civil Procedure 8 answers the same procedural question as Delaware Code title 18, section 6853 and therefore displaces the state requirement.
  3. Whether Rule 8 is valid under the Rules Enabling Act and displaces contrary state law without a separate inquiry into whether the displaced state law is substantive.
  4. Whether Rules 3, 11, or 12 independently permit enforcement of Delaware's affidavit requirement in federal court.

Holdings

  1. When a valid Federal Rule of Civil Procedure answers the disputed procedural question, it governs in federal court and displaces contrary state law, even if the state law would be considered substantive under Erie.
  2. Federal Rule of Civil Procedure 8 displaces Delaware Code title 18, section 6853 because Rule 8 answers the same question concerning what information a plaintiff must provide about the merits of a claim at the outset of litigation and does not permit an additional evidentiary showing through an affidavit of merit.
  3. Federal Rule of Civil Procedure 11 does not preserve Delaware's affidavit-of-merit requirement because Rule 11's reference to affidavits concerns verification by an attorney or party, not affidavits supplied by third-party medical professionals.
  4. Rule 8 is valid under the Rules Enabling Act because it regulates procedure, and its validity does not depend on whether the displaced state law is substantive or serves a substantive purpose.

Key quotations

Thus, a valid Rule of Civil Procedure displaces contrary state law even if the state law would qualify as substantive under Erie’s test. (4)
We first ask whether the Federal Rule “answers the question in dispute.” (4)
Unless the Federal Rules single out a claim for special treatment, see, e.g., Fed. Rule Civ. Proc. 9, Rule 8 sets a ceiling on the information that plaintiffs can be required to provide about the merits of their claims. (6)
To determine whether a Rule is valid under the Rules Enabling Act, the only question is whether it “really regulates procedure.” (11)

Factual background

While visiting Delaware, Harold Berk fell from a bed and fractured his ankle. At a hospital owned by Beebe Medical Center, Dr. Choy recommended a protective boot, but employees forced Berk's leg into the boot and twisted the fractured ankle; Dr. Choy did not immediately order another X ray. A later X ray showed severe deformity requiring surgery, after which Berk brought a Delaware medical-malpractice action without the required affidavit of merit.

Procedural history

Berk sued Dr. Wilson Choy and Beebe Medical Center in federal court under Delaware law based on diversity jurisdiction. The District Court dismissed the action because Berk did not file the affidavit required by Delaware Code title 18, section 6853, and the Third Circuit affirmed. The Supreme Court granted certiorari, reversed, and remanded.

Remand instructions

The judgment of the Third Circuit was reversed and the case remanded for further proceedings consistent with the opinion; Delaware's affidavit-of-merit requirement may not be enforced in federal court.
