Supplemental jurisdiction - sustany/dvg GitHub Wiki

A way for federal courts to hear claims for which they would not ordinarily have jurisdiction. �Supplemental jurisdiction only exists in the situation where a lawsuit consists of more than one claim, and the federal court has valid jurisdiction (either diversity jurisdiction or federal question jurisdiction) over at least one of the claims. � In that situation, if the federal claim and the other claims arise out of a "common nucleus of operative fact," then the court may (but does not have to) exercise�supplemental jurisdiction to hear the other claims as well. �United Mine Workers v Gibbs, 383 US 715 (1966).
