Cessions of legislative jurisdiction are free not only from the requirements of article I, section 8, clause 17, as to purchase--and, with it, ownership--but they are also free from the requirement that the property be used for one of the purposes enumerated in clause 17, assuming that however broad those purposes are under modern decisions the term "other needful Buildings" used therein may have some limitation. In Collins v. Yosemite Park Co., 304 U.S. 518 (1938), in which the Supreme Court sustained the exercise of Federal legislative jurisdiction acquired pursuant to a State cession statute, it was said (pp. 529-530):
* * * There is no question about the power of the United States to exercise jurisdiction secured by cession, thought this is not provided for by Clause 17. And it has been held that such a cession may be qualified. It has never been necessary, heretofore, for this Court to determine whether or not the United States has the constitutional right to exercise jurisdiction over territory, within the geographical limits of a State, acquired for purposes other than those specified in Clause 17. It was raised but not decided in Arlington Hotel v. Fant, 278 U.S. 439, 454. It was assumed without discussion in Yellowstone Park Transportation Co. v. Gallatin County, 31 F.2d 644. On account of the regulatory phases of the Alcoholic Beverage control Act of California, it is necessary to determine that question here. The United States has large bodies of public lands. These properties are used for forests, parks, ranges, wild life sanctuaries, flood control, and other purposes which are not covered by Clause 17. In Silas Mason Co. v. Tax commission of Washington, 302 U.S. 186, we upheld in accordance with the right of the United States to acquire private property for use in "the reclamation of arid and semiarid lands" and to hold its purchases subject to state jurisdiction. In other instances, it may be deemed important or desirable by the
National Government and the State Government in which the particular property is located that exclusive jurisdiction be vested in the United States by cession or consent. No question is raised as to the authority to acquire land or provide for national parks. As the National Government may, "by virtue of its sovereignty" acquire lands within the border of states by eminent domain and without their consent, the respective sovereignties should be in a position to abject their jurisdiction. There is no constitutional objecting to such an adjustment of right. * * *
This quoted excerpt suggests that the Federal Government may exercise legislative jurisdiction, ceded to it by a State, over any area which it might own, acquire, or use for Federal purposes. In Bowen v. Johnston, 306 U.S. 19 (1939), the Supreme Court again indicated that it was constitutionally permissible for the Federal Government to exercise over a national park area legislative jurisdiction which might be ceded to it by a State...
LIMITATIONS ON AREAS OVER WHICH JURISDICTION MAY BE RETAINED BY FEDERAL RESERVATION: The courts have not, apparently, had occasion to consider whether any limitations exist with respect to the types of areas in which the Federal Government may exercise legislative jurisdiction by reservation at the time of granting statehood. There appears, however, to be no reason for concluding that Federal legislative jurisdiction may not be thus retained with respect to all the variety of areas over which Federal legislative jurisdiction may be ceded by a State.
