Royal Canin U.S.A. v. Wullschleger

Question Presented

(1) Whether a post-removal amendment of a complaint to omit federal questions defeats federal-question subject matter jurisdiction pursuant to 28 U.S.C. § 1331; and (2) whether such a post-removal amendment of a complaint precludes a district court from exercising supplemental jurisdiction over the plaintiff’s remaining state-law claims pursuant to 28 U.S.C. § 1367.
