Ashley Keller, a founding partner of Keller Postman LLC representing Wullschleger, argued that federal jurisdiction should align with the current claims in the complaint. “A suit arises under the law that creates the cause of action,” Keller told the court, adding that adhering to this principle avoids constitutional issues and unnecessary litigation over jurisdiction.
The ruling resolves the jurisdictional dispute but does not address the merits of Wullschleger’s allegations that Royal Canin and Nestlé Purina misrepresented their prescription dog foods. The case will now proceed in state court.
Royal Canin and Nestlé are represented by Katherine Wellington of Hogan Lovells.
The consumers are represented by Ashley C. Keller of Keller Postman LLC.
The case is Royal Canin USA Inc. et al. v. Wullschleger et al., case number 23-677, in the Supreme Court of the United States.
