MEMORANDUM ***

Joseph Diaz and Luis Campas brought a 20-count, 51-page complaint against a dozen defendants. Diaz and Campas claim that one defendant wrote them a bad check, and that when they tried to have that defendant prosecuted, the other defendants retaliated against them by, among other things, taking away their boxing licenses. (Diaz is a trainer and Cam-pas a boxer.) The district court granted the defendants’ motions to dismiss under Rule 12(b)(6) of the Federal Rules of Civil Procedure. Campas and Diaz appeal. Jurisdiction lies under 28 U.S.C. § 1291. We review de novo, Knievel v. ESPN, 393 F.3d 1068, 1072 (9th Cir. 2005), and affirm for the reasons stated by the district court.

AFFIRMED.
