MEMORANDUM **

Frank B. Cockrell, II, a California state prisoner, appeals pro se from the district court’s order dismissing his 42 U.S.C. § 1983 action as barred by Heck v. Humphrey, 512 U.S. 477, 114 S.Ct. 2364, 129 L.Ed.2d 383 (1994). We have jurisdiction pursuant to 28 U.S.C. § 1291. We review de novo a dismissal pursuant to 28 U.S.C. § 1915(e). Huftile v. Miccio-Fonseca, 410 F.3d 1136 (9th Cir. 2005). We affirm.

The district court properly dismissed the action alleging that the defendants engaged in a conspiracy leading to Cockrell’s criminal convictions because judgment in Cockrell’s favor would necessarily imply the invalidity of those convictions, and Cockrell has failed to demonstrate that his convictions have been invalidated. See Heck, 512 U.S. at 487, 114 S.Ct. 2364.

Cockrell’s remaining contentions are unpersuasive.

AFFIRMED.
