MEMORANDUM **

California state prisoner Ramon Birl appeals from the district court’s judgment denying his 28 U.S.C. § 2254 habeas petition. We have jurisdiction under 28 U.S.C. § 2253, and we affirm.

Birl contends that the Board’s 2004 decision to deny him parole was not supported by “some evidence” and therefore violated his due process rights. The only federal right at issue in the parole context is procedural, and the only proper inquiry is what process the inmate received, not whether the state court decided the case correctly. See Swarthout v. Cooke, — U.S. -, 131 S.Ct. 859, 862-63, 178 L.Ed.2d 732 (2011); Pearson v. Muntz, 639 F.3d 1185, 1191 (9th Cir. 2011). Because Birl raises no procedural challenges, we affirm.

We deny Birl’s request for supplemental briefing.

AFFIRMED.
