MEMORANDUM **
Federal prisoner Donald Lewis Davis appeals pro se from the district courts judgement dismissing for failure to state a claim his action regarding his prison orientation and loss of good time credits. We have jurisdiction under 28 U.S.C. § 1291. We review de novo the district courts dismissal under 28 U.S.C. § 1915A. Resnick v. Hayes, 213 F.3d 443, 447 (9th Cir. 2000). We affirm.
The district court properly dismissed Daviss action because Davis failed to allege facts sufficient to state a plausible claim. See Hebbe v. Pliler, 627 F.3d 338, 341-42 (9th Cir. 2010) (although pro se pleadings are construed liberally, a plaintiff must allege facts sufficient to state a plausible claim); see also Wolff v. McDonnell, 418 U.S. 539, 563-68, 94 S.Ct. 2963, 41 L.Ed.2d 935 (1974) (due process requirements for prison disciplinary proceedings); Cousins v. Lockyer, 568 F.3d 1063, 1070 (9th Cir. 2009) (failure to follow internal prison policy does not amount to a constitutional violation).
To the extent that Davis challenged the loss of good time credits, the district court properly dismissed Daviss claim because he failed to allege facts sufficient to show that the disciplinary proceeding resulting in the loss of good time credits had been invalidated. See Heck v. Humphrey, 512 U.S. 477, 486-87, 114 S.Ct. 2364, 129 L.Ed.2d 383 (1994) (if “a judgment in favor of the plaintiff would necessarily imply the invalidity of his conviction or sentence ․ the complaint must be dismissed unless the plaintiff can demonstrate that the conviction or sentence has already been invalidated”); see also Edwards v. Balisok, 520 U.S. 641, 648, 117 S.Ct. 1584, 137 L.Ed.2d 906, (1997) (extending Heck to prison disciplinary proceedings resulting in the loss of good-time credits).
AFFIRMED.
