MEMORANDUM **

Roberto Herrera, a California state prisoner, appeals pro se from the district court’s judgment in his 42 U.S.C. § 1983 action alleging that defendants violated his constitutional rights in obtaining a state court criminal conviction. We have jurisdiction under 28 U.S.C. § 1291. We review de novo. Guerrero v. Gates, 442 F.3d 697, 703 (9th Cir. 2006) (dismissal under Fed.R.Civ.P. 12(b)(6)); Whitaker v. Gar-cetti, 486 F.3d 572, 579 (9th Cir. 2007) (dis *615 missal under Heck v. Humphrey, 512 U.S. 477, 114 S.Ct. 2364, 129 L.Ed.2d 383 (1994)). We affirm.

The district court properly dismissed Herrera’s action for damages as Heck-barred because if successful, his claims would necessarily imply the invalidity of his conviction, and Herrera has not demonstrated that his conviction has been overturned. See Heck, 512 U.S. at 486-87, 114 S.Ct. 2364 (the district court must dismiss a damages action, which, if successful, would necessarily imply the invalidity of a conviction, absent a showing that the conviction has been overturned).

Herrera’s motion for copies of certain district court documents, filed on March 16, 2015, is denied as moot.

AFFIRMED.
