Let's start with the case name: United States v. Nature. Seems timely.
Anyway, in United States v. Nature, --- F.3d ---, No. 17-10161 (9th Cir. 2018), the Court affirmed the defendant’s conviction for being dangerously under the influence of alcohol in violation of 36 C.F.R. § 34.5(b)(21), while he was in the El Portal Administrative Site, which is adjacent to Yosemite National Park.
The only reason for publishing this case seems to be the brief discussion of "mutatis mutandis," meaning making necessary alterations while not affecting the main point.
The Ninth Circuit used this doctrine to incorporate the relevant dangerous-drinking-prohibition into the regulations applicable to the Site.
