Civil Procedure—Supplemental Jurisdiction Extended to Plaintiffs in Diversity Jurisdiction Cases with Claims Less Then $75,000—Exxon Mobil Corporation v. Allapattah Services, Inc., 125 S. Ct. 2611 (2005)

The federal courts derive subject matter jurisdiction from Congress as outlined in the United States Constitution.  By enacting 28 U.S.C. § 1367, Congress granted federal courts supplemental jurisdiction over claims where original subject matter jurisdiction is already established.  In Exxon Mobil Corp. v. Allapattah Services, Inc., the Supreme Court considered whether § 1367 is applicable to plaintiffs permissively joined or who form part of a class action, but fail to meet the amount-in-controversy requirement of § 1332(a).  The Court determined that § 1367 is applicable to such plaintiffs if at least one named plaintiff meets the amount-in-controversy requirement of § 1332(a). . . .
