In Baldwin v. Fish & Game Commission of Montana, 436 U.S. 371, 98 S.Ct. 1852, 56 L.Ed.2d 354 (1978), the Supreme Court considered whether Montana's preference for residents in access to recreational elk hunting violated the Privileges and Immunities Clause. The Court explained the limited reach of this constitutional provision, "Only with respect to those `privileges' and `immunities' bearing upon the vitality of the Nation as a single entity must the State treat all citizens, resident and nonresident, equally." Id. at 383, 98 S.Ct. 1852.
