three counts of committing a lewd act on a child. He was sentenced to fifteen
consecutive terms of fifteen years to life. We have jurisdiction under 28 U.S.C.
§ 2253, and we affirm.1
We review de novo a district court’s denial of a 28 U.S.C. § 2254 habeas
corpus petition. Patsalis v. Shinn, 47 F.4th 1092, 1097 (9th Cir. 2022). We review
ineffective assistance of counsel claims in the context of excusing a procedural
default de novo. Visciotti v. Martel, 862 F.3d 749, 769 (9th Cir. 2016).
Nunez’s ex post facto claim is procedurally defaulted. Nunez claims that the
trial court violated the ex post facto clause by sentencing him on his three lewd act
counts under the law in effect at the time of his sentencing rather than at the time of
his offenses. The state court deemed Nunez’s claim forfeited under California’s
contemporaneous objection rule because he did not request probation or object to
the lack of probation at his sentencing hearing.
We may not hear a claim in a habeas action that has been “decided by a state
court if the decision of that court rests on a state law ground that is independent of
the federal question and adequate to support the judgment.” Coleman v. Thompson,
501 U.S. 722, 729 (1991). We must defer to the state court’s determination that
Nunez forfeited his claim because that determination is an independent and adequate

state ground for the court’s decision. See Zapata v. Vasquez, 788 F.3d 1106, 1111–
12 (9th Cir. 2015) (finding claim procedurally defaulted under California’s
contemporaneous objection rule).
Nunez argues that ex post facto claims are exempted from forfeiture under
California law. But the state court rejected that argument, and because “state courts
are the ultimate expositors of state law,” we must abide “by the state’s construction”
unless it seems “that its interpretation is an obvious subterfuge to evade the
consideration of a federal issue.” Peltier v. Wright, 15 F.3d 860, 862 (9th Cir. 1994)
(citation omitted). There is no indication of any such dubious state conduct here.
Next, Nunez contends that even if he forfeited his claim, he could excuse the
procedural default under Coleman’s “cause and prejudice” standard because his
attorney rendered ineffective assistance by failing to object at sentencing. 501 U.S.
at 750. “[C]ounsel’s ineffectiveness will constitute cause only if it is an independent
constitutional violation,” id. at 755, so Nunez must meet the standard for ineffective
assistance set out in Strickland v. Washington, 466 U.S. 668 (1984). Strickland
requires the defendant to show prejudice from any deficient representation by
counsel. See Garza v. Idaho, 586 U.S. 232, 237 (2019) (quoting Strickland, 466
U.S. at 692).
Nunez cannot show prejudice. To show prejudice under Strickland, “there
[must be] a reasonable probability that,” but for the attorney error, “the result of the
3 23-2562
proceeding would have been different.” 466 U.S. at 694. Here, if Nunez’s counsel
had requested probation, the trial court’s statements at sentencing suggest a strong
probability that the outcome for Nunez would have remained the same. And even
in the unlikely event that the trial court granted Nunez probation on the three lewd
act counts, Nunez cannot show prejudice because he would nonetheless serve what
is effectively a life sentence. The trial court sentenced him to twelve consecutive
terms of fifteen years to life for his rape counts.
Because Nunez cannot prove his attorney’s lack of objection prejudiced him
under Strickland’s standard, he cannot show the cause necessary to excuse his
procedural default. Hence Nunez’s claim is procedurally defaulted.
AFFIRMED.
