Keller Postman LLC Celebrates Unanimous Victory for Plaintiffs at the U.S. Supreme Court

Keller Postman LLC is proud to announce that it has secured a momentous victory for plaintiffs across the country: The U.S. Supreme Court unanimously affirmed the appellate court’s decision in Royal Canin U.S.A., Inc. v. Wullschleger, reconfirming that plaintiffs are the masters of their complaints. Specifically, Justice Kagan’s opinion makes clear that when a plaintiff removes all federal claims from her complaint, federal courts are not allowed to interfere with the plaintiff’s decision to have her case heard in state court. The Supreme Court also made clear that this principle is a jurisdictional rule, such that when a plaintiff amends her complaint to destroy the basis for removal jurisdiction, the district court has no discretion to keep the case but rather must remand the case back to state court.

The Supreme Court’s decision marks a sharp break from past practice, where plaintiffs were stripped of authority to dictate their choice of forum, even if they eliminated all federal claims from their complaints. Keller Postman Co-Founder Ashley Keller argued the case for respondents, and Noah Heinz played an integral role in briefing the jurisdictional dispute and helping Ashley prepare for oral argument.

Keller Postman Makes Second Argument Before the U.S. Supreme Court

On the first day of the 2024 term, Keller Postman Co-Founder Ashley Keller made his second oral argument before the Supreme Court. Representing respondents in Royal Canin U.S.A. Inc. v. Wullschleger, Keller Postman defended the principle that a plaintiff is the master of her suit, such that amending out federal claims deprives federal courts of supplemental jurisdiction to adjudicate state-law claims. That rule, Keller Postman maintains, should apply in both original and removed cases.

Appearing on Monday at counsel’s table was Associate Noah Heinz, who was instrumental in writing respondents’ brief on the merits and helping Ashley prepare for oral argument. A decision in the case is expected by June of 2025.
