MEMORANDUM **
Former California state prisoner Michael Grimes appeals pro se from the district courts judgment dismissing his 42 U.S.C. § 1983 action alleging various constitutional claims. We have jurisdiction under 28 U.S.C. § 1291. We review de novo a dismissal under Federal Rule of Civil Procedure 12(b)(6). Hebbe v. Pliler, 627 F.3d 338, 341 (9th Cir. 2010). We affirm.
The district court properly dismissed Grimess deliberate indifference claim because Grimes failed to allege facts sufficient to show that defendants knew of and disregarded an excessive risk to Grimess health or safety. See Farmer v. Brennan, 511 U.S. 825, 837, 114 S.Ct. 1970, 128 L.Ed.2d 811 (1994) (a prison official cannot be held liable for deliberate indifference “unless the official knows of and disregards an excessive risk to inmate health or safety; the official must both be aware of facts from which the inference could be drawn that a substantial risk of serious harm exists, and he must also draw the inference”).
The district court properly dismissed Grimess due process claim because Grimes failed to allege facts sufficient to show that the disciplinary decision was not supported by some evidence. See Superintendent v. Hill, 472 U.S. 445, 455, 105 S.Ct. 2768, 86 L.Ed.2d 356 (1985) (requirements of due process are satisfied if “some evidence” supports the disciplinary decision).
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).
Grimess motion to dismiss case without prejudice is denied as moot.
AFFIRMED.
