Appeal from the United States District Court for the District of Idaho Amanda K. Brailsford, District Judge, Presiding Submitted July 29, 2026**

Before: McKEOWN, TALLMAN, MENDOZA, JR., Circuit Judges.

James Newlin appeals pro se the district court’s judgment dismissing his action alleging federal and state law claims. We have jurisdiction under 28 U.S.C. § 1291. We review de novo the district court's dismissal under Federal Rule of

*

This disposition is not appropriate for publication and is not precedent except as provided by Ninth Circuit Rule 36-3.

Civil Procedure 12(b)(6) on the basis of claim preclusion. V.V.V. & Sons Edible Oils Ltd. v. Meenakshi Overseas, LLC, 946 F.3d 542, 545 (9th Cir. 2019). We affirm.

The district court properly dismissed Newlin’s action as barred by claim preclusion because Newlin raised, or could have raised, his claims in a prior action, which involved the same parties or their privies and resulted in a final judgment on the merits. See Tahoe-Sierra Pres. Council, Inc. v. Tahoe Reg'l Plan. Agency, 322 F.3d 1064, 1077 (9th Cir. 2003) (setting forth elements of claim preclusion under federal law).

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).

AFFIRMED.
