Exxon Mobil Corp. v. Allapattah Services, Inc.

Exxon Mobil Corp. v. Allapattah Services, Inc. (2005) was a Supreme Court case addressing federal court jurisdiction. The issue was whether a federal court could hear a lawsuit asserting multiple claims under federal and state law if only some claims involved "federal question" (federal law). The Court ruled that as long as at least one claim involves federal law, the court can hear the entire case, even if other claims are solely under state law. This decision helps prevent fragmented litigation and allows for more efficient resolution of complex disputes involving multiple claims.
