However, any such waiver must be made "voluntarily, knowingly, and intelligently." Marsh, 105 F.3d at 111; see Lake James Community Volunteer Fire Dep't, Inc. v. Burke County, 149 F.3d 277, 280 (4th Cir. 1998), cert. denied, 525 U.S. 1106, 119 S.Ct. 874, 142 L.Ed.2d 775 (1999); United States v. Local 1804-1, 44 F.3d 1091, 1098 n. 4 (2d Cir. 1995); Leonard v. Clark, 12 F.3d 885, 889-90 (9th Cir. 1993); Erie Telecommunications, 853 F.2d at 1094; Sambo's Restaurants, 663 F.2d at 690. Moreover, the waiver must be established by "clear and compelling" evidence.
Because we conclude that Public Lands Council has standing, we need not consider whether American Farm Bureau Federation also has standing. See Leonard v. Clark, 12 F.3d 885, 888 (9th Cir. 1993). Intervenors also challenge Plaintiffs' standing to assert their claims.
NRDC, Amigos Bravos, and Powder River have demonstrated, to this Court's satisfaction, association standing under the broad standing requirement applicable here. See Leonard v. Clark, 12 F.3d 885, 888 (9th Cir. 1994) (explaining that once the court determines that one of the plaintiffs has standing, it need not decide the standing of the others). V. STANDARD OF REVIEW
Given this conclusion, the Court need not address the standing of other Plaintiffs. “The general rule applicable to federal court suits with multiple plaintiffs is that once the court determines that one of the plaintiffs has standing, it need not decide the standing of the others.” Leonard v. Clark, 12 F.3d 885, 888 (9th Cir.1993); see W. Watersheds Project v. Kraayenbrink, 632 F.3d 472, 484 n. 7 (9th Cir.2011). B. Merits.
