McMahon

MEMORANDUM **

Patrick R. McMahon appeals pro se the district court’s judgment dismissing his action against Pier 39, Bay Marina Management, Inc., and the City and County of San Francisco (“defendants”), and the district court’s orders granting defendants’ motion for sanctions pursuant to Fed.R.Civ.P. 11 and motion to enter a vexatious litigant order against McMahon. We have jurisdiction under 28 U.S.C. § 1291 . We review de novo a dismissal for failure to state a claim, Decker v. Advantage Fund, Ltd., 362 F.3d 593, 596-97 (9th Cir.2004), and the district court’s determination that res judicata applies, Gregory v. Widnall, 153 F.3d 1071, 1074 (9th Cir.1998). We review for abuse of discretion a vexatious litigant order, De Long v. Hennessey, 912 F.2d 1144, 1146 (9th Cir.1990), an award of Rule 11 sanctions, G.C. & K.B. Investments, Inc. v. Wilson, 326 F.3d 1096, 1109 (9th Cir.2003), and denial of a motion for leave to amend, Johnson v. Buckley, 356 F.3d 1067, 1077 (9th Cir.2004). We affirm.

The district court properly determined that all but one of McMahon’s claims were proscribed by the doctrine of res judicata. See Tahoe-Sierra Pres. Council, Inc. v. Tahoe Reg’l Planning Agency,…
