SWC, LLC v. Herr

(1) Whether the United States Forest Service"s powers under the property clause of the Constitution to limit gas-powered motorboat use on lakes in congressionally designated wilderness areas are dependent upon and subservient to whether a state has first acted to restrict motorboat activities on the same lakes; and (2) whether prior existing uses of property near the many national wilderness areas are immunized from and ossified against regulations to achieve the Wilderness Act of 1964"s goal to protect wildernesses and keep them "unimpaired for future use and enjoyment as wilderness," 16 U.S.C. § 1131(a).
