NOT FOR PUBLICATION FILED UNITED STATES COURT OF APPEALS MAR 21 2025 MOLLY C. DWYER, CLERK U.S. COURT OF APPEALS FOR THE NINTH CIRCUIT DOUGLAS WAYNE DERELLO, Jr., No. 23-1944 D.C. No. 2:22-cv-00348-MTL Plaintiff - Appellant, v. MEMORANDUM* UNKNOWN BACKES, CO IV; UNKNOWN STICKLEY, DW; UNKNOWN MORRIS, Defendants - Appellees.

Appeal from the United States District Court for the District of Arizona Michael T. Liburdi, District Judge, Presiding Submitted March 17, 2025** Before: CANBY, R. NELSON, and FORREST, Circuit Judges.

Arizona state prisoner Douglas Wayne Derello, Jr., appeals pro se from the district court’s summary judgment for failure to exhaust administrative remedies in his 42 U.S.C. § 1983 action alleging deliberate indifference and retaliation. We

* This disposition is not appropriate for publication and is not precedent except as provided by Ninth Circuit Rule 36-3. ** The panel unanimously concludes this case is suitable for decision without oral argument. See Fed. R. App. P. 34(a)(2). have jurisdiction under 28 U.S.C. § 1291. We review de novo. Williams v. Paramo, 775 F.3d 1182, 1191 (9th Cir. 2015). We affirm.

The district court properly granted summary judgment because Derello failed to exhaust administrative remedies and failed to raise a genuine dispute of material fact as to whether administrative remedies were unavailable to him. See Ross v. Blake, 578 U.S. 632, 642-44 (2016) (explaining that an inmate must exhaust such administrative remedies as are available before bringing suit, and describing limited circumstances in which administrative remedies are unavailable).

We do not consider arguments and allegations raised for the first time on appeal. See Padgett v. Wright, 587 F.3d 983, 985 n.2 (9th Cir. 2009).

AFFIRMED.
