'Inherent powers' are defined in Black's Law Dictionary as 'powers over and beyond those explicitly granted in the Constitution or reasonably to be implied from express grants[.]' Black's Law Dictionary 782 (6th ed. 1990).
A district court possesses inherent power over the administration of its business. It has inherent authority to regulate the conduct of attorneys who appear before it, Chambers v. NASCO, Inc., 501 U.S. 32, 43 (1991), to promulgate and enforce rules for the management of litigation, Thomas v. Arn, 474 U.S. 140, 146 (1985), to punish contempt, Young v. United States, 481 U.S. 787, 793 (1987), and to remand cases involving pendent claims. Carnegie-Mellon Univ. v. Cohill, 484 U.S. 343, 357 (1988). A federal court's inherent authority to manage its docket and maintain proper decorum does not authorize it to carve out exceptions to remedies expressly provided by Congress.
