AMENDED MEMORANDUM

California state prisoner Larry P. Contero appeals pro se from the district court’s judgment denying his habeas petition under 28 U.S.C. § 2254. We have jurisdiction under 28 U.S.C. § 1291. We review de novo, Sass v. Cal. Bd. of Prison Terms, 461 F.3d 1123, 1126 (9th Cir.2006), and we affirm.

We reject as foreclosed the State’s contention that this court lacks jurisdiction to entertain this appeal because Contero did not obtain a certificate of appealability. See Rosas v. Nielsen, 428 F.3d 1229, 1231-32 (9th Cir.2005) (per curiam).

The California courts’ rejection of Contero’s claims was neither contrary to nor an unreasonable application of clearly established federal law. See 28 U.S.C. § 2254(d)(1). We reject as foreclosed Contero’s contention that he has a protected liberty interest in the accrual of work credits. See Toussaint v. McCarthy, 801 F.2d 1080, 1094-95 (9th Cir.1986). Accordingly, we evaluate under the rational-basis test his contention that California’s 15% cap on work credits he may earn toward his sentence, see CahPenal Code § 2933.1(a), violates his Fourteenth Amendment guarantee of equal protection. See Kalka v. Vasquez, 867 F.2d 546, 547 (9th Cir.1989). We agree with the district court that the state’s interest in treating violent felons more harshly provides a rational basis for California’s requirement that Contero, who was convicted of voluntary manslaughter, serve at least 85% of his sentence. See id.

Contero’s estoppel contention does not state a violation of federal law and is thus not cognizable in these proceedings. See Lewis v. Jeffers, 497 U.S. 764, 780, 110 S.Ct. 3092, 111 L.Ed.2d 606 (1990) (“[Federal habeas corpus relief does not lie for errors of state law.”).

Finally, we decline to address claims Contero has raised for the first time on appeal, including Contero’s contention that he has been unlawfully deprived of good-conduct credits. See Allen v. Ornoski, 435 F.3d 946, 960 (9th Cir.), cert. denied, 546 U.S. 1136, 126 S.Ct. 1140, 163 L.Ed.2d 944 (2006).

AFFIRMED.
