Ernst & Young LLP v. Louisiana Office of Financial Institutions

2026 CW 0188 · Louisiana Court of Appeal, First Circuit · April 16, 2026 · No. 2026 CW 0188

Summary

The Louisiana Court of Appeal, First Circuit, granted supervisory writs and reversed the trial court’s grant of the Louisiana Office of Financial Institutions’ peremptory exception of res judicata. The court held that the federal court’s dismissal based on Eleventh Amendment sovereign immunity was for lack of subject-matter jurisdiction and therefore was not a judgment on the merits, vacated the denial of Ernst & Young’s La. R.S. 6:103 motion, and remanded for further proceedings.

Questions Presented

  1. Whether a federal-court dismissal based on Eleventh Amendment sovereign immunity constitutes a final judgment on the merits supporting res judicata in a subsequent state-court action.
  2. Whether the trial court properly denied Ernst & Young's La. R.S. 6:103 motion after granting the exception of res judicata.

Holdings

  1. A dismissal based on a federal court's lack of subject matter jurisdiction, including dismissal on Eleventh Amendment sovereign-immunity grounds, is not a final judgment on the merits for purposes of res judicata in a subsequent court that has competent jurisdiction.
  2. The trial court's denial of Ernst & Young's La. R.S. 6:103 motion must be vacated because the trial court must first rule on the Louisiana Office of Financial Institutions' remaining exceptions and then rule on the disclosure motion.

Key quotations

When a federal court lacks jurisdiction over the subject matter of a claim, a dismissal of the claim on those grounds is not considered to be a final judgment on the merits in a subsequent court that does have competent jurisdiction.
A dismissal for want of jurisdiction bars access to federal courts and is res judicata only of the lack of a federal court's power to act

Factual background

Ernst & Young sought documents and information from the Louisiana Office of Financial Institutions under La. R.S. 6:103. The agency relied on a prior federal-court dismissal in Fed. Deposit Ins. Corp. v. Ernst & Young LLP, but that federal court had determined that the agency was protected by Eleventh Amendment sovereign immunity and that the federal court lacked jurisdiction over it.

Procedural history

Ernst & Young filed a La. R.S. 6:103 motion in the Nineteenth Judicial District Court for East Baton Rouge Parish seeking three categories of documents from the Louisiana Office of Financial Institutions. The trial court granted the agency's exception of res judicata and denied Ernst & Young's disclosure motion. The Louisiana Court of Appeal granted supervisory writs, reversed the res judicata ruling, vacated the denial of the disclosure motion, and remanded for further proceedings.

Remand instructions

The trial court must rule on the Louisiana Office of Financial Institutions' remaining exceptions and then rule on Ernst & Young's La. R.S. 6:103 Motion to Order Disclosures of Documents and Information.
