Newsome

MEMORANDUM **

Derrick J. Newsome, an Arizona state prisoner, appeals pro se the district court’s sua sponte dismissal of Newsome’s civil rights action alleging that his due process rights were violated in a prison disciplinary hearing which deprived him of good time credits. We have jurisdiction pursuant to 28 U.S.C. § 1291 , and we affirm.

We review de novo a dismissal under the screening provisions of the Prison Litigation Reform Act, 28 U.S.C. §§ 1915A(a), 1915A(b)(1) & (2). See Barren v. Harrington, 152 F.3d 1193, 1194 (9th Cir.1998) *363 (order), cert. denied, 525 U.S. 1154 , 119 S.Ct. 1058 , 143 L.Ed.2d 68 (1999). Newsome’s action is barred by Heck v. Humphrey, 512 U.S. 477, 483-84 , 114 S.Ct. 2364 , 129 L.Ed.2d 383 (1994), because Newsome’s claims challenge the duration of his confinement, and Newsome may not bring such a 42 U.S.C. § 1983 action unless and until his disciplinary conviction is overturned. See Edwards v. Balisok, 520 U.S. 641, 647 , 117 S.Ct. 1584 , 137 L.Ed.2d 906 (1997).

AFFIRMED.
