Appeal from the United States District Court
for the District of Arizona
Raner C. Collins, District Judge, Presiding
Submitted November 12, 2025**
Before: SCHROEDER, RAWLINSON, and NGUYEN, Circuit Judges.
Arizona state prisoner Mario Armando Obregon 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 Fourteenth Amendment violations arising

from his pretrial detention. We 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 Obregon
failed to exhaust his administrative remedies or raise a genuine dispute of material
fact as to whether administrative remedies were effectively 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 under which administrative remedies are
effectively unavailable); Woodford v. Ngo, 548 U.S. 81, 90 (2006) (stating that
proper exhaustion requires “using all steps that the agency holds out, and doing so
properly (so that the agency addresses the issues on the merits)” (emphasis,
citation, and internal quotation marks omitted)).
The district court did not abuse its discretion by denying Obregon’s motion
to set aside the judgment because Obregon failed to set forth any basis for relief.
See Sch. Dist. No. 1J, Multnomah County, Or. v. ACandS, Inc., 5 F.3d 1255, 1262-
63 (9th Cir. 1993) (setting forth standard of review and grounds for a motion under
Fed. R. Civ P. 59(e)).
2 24-350
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.
