   MEMORANDUM

California state prisoner Tony Campbell appeals pro se from the district court’s judgment dismissing for failure to state a claim his 42 U.S.C. § 1983 action alleging defendant violated his due process rights during disciplinary proceedings. We have jurisdiction under 28 U.S.C. § 1291. We review de novo the district court’s dismissal pursuant to 28 U.S.C. § 1915A, Ramirez v. Galaza, 334 F.3d 850, 853-54 (9th Cir.2003), and we affirm.

Campbell’s due process claim challenged the propriety of a disciplinary proceeding that resulted in the loss of 90 days of good-time credit. The district court properly dismissed the claim because Campbell did not allege that the punishment had been invalidated. See Edwards v. Balisok, 520 U.S. 641, 646-48, 117 S.Ct. 1584, 137 L.Ed.2d 906 (1997) (holding that a due process claim challenging disciplinary proceeding that necessarily implies the invalidity of the deprivation of good-time credits is not cognizable under section 1983).

The remaining contentions lack merit.

AFFIRMED.
