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.
