   MEMORANDUM

Washington state prisoner Tommie Lee Stewart appeals pro se from the district court’s judgment dismissing his petition under 28 U.S.C. § 2254. We have jurisdiction' under 28 U.S.C. § 1291. We review de novo, Beardslee v. Woodford, 358 F.3d 560, 568 (9th Cir.2004), and we affirm.

The district court did not err when it dismissed Stewart’s challenge to the authority of the Washington Indeterminate Sentence Review Board to rescind its earlier decision to discharge him from parole. Stewart based that challenge solely on state law, and “a violation of state law standing alone is not cognizable in federal court on habeas.” Park v. California, 202 F.3d 1146, 1149 (9th Cir.2000) (citing Estelle v. McGuire, 502 U.S. 62, 67, 112 S.Ct. 475, 116 L.Ed.2d 385 (1991)). For the fust time in this court, Stewart contends that the Board’s action deprived him of a federally protected liberty interest. We decline to consider this contention. See Wildman v. Johnson, 261 F.3d 832, 840 (9th Cir. 2001).

In order for Stewart to challenge the Board’s action in this court, he did not require a certificate of appealability. See Rosas v. Nielsen, 428 F.3d 1229, 1231-32 (9th Cir.2005) (per curiam). However, before this court Stewart also raises contentions regarding his 1975 assault conviction that have not been certified for appeal. We deny a certificate of appealability with respect to these contentions. See Slack v. McDaniel, 529 U.S. 473, 483-84, 120 S.Ct. 1595, 146 L.Ed.2d 542 (2000).

AFFIRMED.
