Exclusive Legislative Jurisdiction Law and Legal Definition

Exclusive legislative jurisdiction refers to the jurisdiction exercised by the federal government by displacing state's sovereign authority in that area.

The following is an example of a case law on exclusive legislative jurisdiction:

Exclusive Legislative Jurisdiction is applied when the Federal Government possesses, by whatever method acquired, all of the authority of the State, and in which the State concerned has not reserved to itself the right to exercise any of the authority concurrently with the U.S. except the right to serve civil or criminal process in the area relative to activities which occurred outside the area. This term is applicable even though the State may exercise certain authority over the land pursuant to the authority granted by Congress in several federal statutes permitting the State to do so. [Prof'l Helicopter Pilots Ass'n v. Lear Siegler Servs., 326 F. Supp. 2d 1305, 1310-1311 (D. Ala. 2004)].

Federal exclusive authority over places purchased or ceded is as follows:

To exercise exclusive Legislation in all Cases whatsoever, over such District (not exceeding ten Miles square) as may, by Cession of particular States, and the Acceptance of Congress, become the Seat of the Government of the U.S., and to exercise like Authority over all Places purchased by the Consent of the Legislature of the State in which the Same shall be, for the Erection of Forts, Magazines, Arsenals, dock-Yards, and other needful Buildings. [USCS Const. Art. I, § 8, Cl 17].
