MEMORANDUM*
DEBORAH A. CUMBA,
Defendant - Appellee.
Appeal from the United States District Court
for the Southern District of California
Cathy Ann Bencivengo, District Judge, Presiding
Submitted February 18, 2026**
Before: CALLAHAN, FRIEDLAND, and BRESS, Circuit Judges.
Phillip Walter Simon appeals pro se from the district court’s judgment
dismissing his 42 U.S.C. § 1983 action alleging constitutional claims arising from
a child support case in state court. We have jurisdiction under 28 U.S.C. § 1291.
We review de novo a dismissal under Federal Rule of Civil Procedure 12(b)(6) on

The panel unanimously concludes this case is suitable for decision

the basis of judicial immunity. Sadoski v. Mosley, 435 F.3d 1076, 1077 n.1 (9th
Cir. 2006). We affirm.
The district court properly dismissed Simon’s action because defendant
Cumba is immune from liability. See Moore v. Urquhart, 899 F.3d 1094, 1104 (9th
Cir. 2018) (“Section 1983 . . . provides judicial officers immunity from injunctive
relief even when the common law would not.”); Duvall v. County of Kitsap, 260
F.3d 1124, 1133 (9th Cir. 2001) (describing factors relevant to whether an act is
judicial in nature and subject to absolute judicial immunity); Franceschi v.
Schwartz, 57 F.3d 828, 830 (9th Cir. 1995) (per curiam) (applying judicial
immunity from damage liability to a state court commissioner for acts taken in a
judicial capacity and not in a clear absence of jurisdiction); see also Munoz v.
Superior Ct. of L.A. County, 91 F.4th 977, 980-81 (9th Cir. 2024) (affirming
dismissal of § 1983 claims seeking declaratory and injunctive relief because “state
court judges cannot be sued in federal court in their judicial capacity under the
Eleventh Amendment,” including for prospective injunctive relief); Lund v.
Cowan, 5 F.4th 964, 969 (9th Cir. 2021) (“The Eleventh Amendment does not
permit retrospective declaratory relief.”).
We reject as unsupported by the record Simon’s contentions about judicial
bias, misconduct, and conspiracy.
We do not consider matters not specifically and distinctly raised and argued
2 25-1727
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).
All pending motions and requests are denied.
AFFIRMED.
