MEMORANDUM Lawrence George Hash, a California state prisoner, appeals pro se from the district court’s
summary judgment in his 42 U.S.C. § 1983 action alleging due process violations in connection with a prison disciplinary hearing. We have jurisdiction under 28 U.S.C. § 1291. We review de novo. Toguchi v. Chung, 391 F.3d 1051, 1056 (9th Cir.2004). We affirm. The district court properly granted
summary judgment because Hash failed to raise a genuine dispute of material fact as to whether he was improperly denied procedural protections during his disciplinary hearing. See Superintendent v. Hill, 472 U.S. 445, 454-55, 105 S.Ct. 2768, 86 L.Ed.2d 356 (1985) (setting forth due process requirements in prison disciplinary proceedings). We do not consider matters not specifically and distinctly raised and argued in the opening brief, or arguments and allegations raised for the first time on appeal. See Padgett v. Wright, 587 F.3d 983, 985 n. 2 (9th Cir.2009) (per curiam).
Hash’s contention regarding the alleged denial of a mental health evaluation is unpersuasive. Hash’s opposed motion for judicial notice, filed on April 16, 2013, is denied as unnecessary. We grant defendants’ motion to strike Hash’s Fed. R.App. P. 28(
j) letter, filed on August 14, 2013, because Hash attached evidence that was not part of the district court record. AFFIRMED. This disposition is not appropriate for publication and is not precedent except as provided by 9th Cir. R. 36-3.
