¶2 Nevada state prisoner Julio Smith Parra appeals pro se from the district court’s summary judgment in his 42 U.S.C. § 1983 action alleging retaliation and due process violations. We have jurisdiction under 28 U.S.C. § 1291. We review de novo, Brodheim v. Cry, 584 F.3d 1262, 1267 (9th Cir.2009), and we affirm.
¶3 The district court properly granted summary judgment on Parra’s due process claim because Parra failed to raise a genuine dispute of material fact as to whether he experienced an “atypical and significant hardship ... in relation to the ordinary incidents of prison life” that would give rise to a protected liberty interest. See Sandin v. Conner, 515 U.S. 472, 484, 115 S.Ct. 2293, 132 L.Ed.2d 418 (1995). Contrary to Parra’s contention, the district court was not required to address whether there was “some evidence” to support the disciplinary finding.
¶4 The district court properly granted summary judgment on Parra’s retaliation claim because Parra failed to raise a genuine dispute of material fact as to whether defendant Bryant took an adverse action against Parra in response to Parra’s protected conduct. See id. at 1269-71 (elements of a retaliation claim in the prison context; “a plaintiff must show that his protected conduct was the substantial or motivating factor behind the defendant’s conduct” (citation and internal quotation marks omitted)).
¶5 We do not consider matters not specifically and distinctly raised and argued in the opening brief. See Padgett v. Wright, 587 F.3d 983, 985 n. 2 (9th Cir.2009) (per curiam).
¶6 AFFIRMED.
