MEMORANDUM **

California state prisoner Carl Lee Callegari appeals pro se from the district court’s summary judgment in favor of correctional officers J. Lacy and C. Sharpes *165in his 42 U.S.C. § 1983 action alleging that the defendants filed false disciplinary reports against him in retaliation for his filing a lawsuit against the prison. We have jurisdiction pursuant to 28 U.S.C. § 1291. We review de novo a district court’s grant of summary judgment, Barnett v. Centoni, 31 F.3d 813, 815 (9th Cir. 1994) (per curiam), and we affirm.

The district court properly granted summary judgment on Callegari’s retaliation claims because Callegari offered only his unsupported hypothesis that defendants acted out of an improper motive. See Nelson v. Pima Community College, 83 F.3d 1075, 1081-82 (9th Cir. 1996) (“[M]ere allegation and speculation do not create a factual dispute for purposes of summary judgment.”).

The defendants’ failure to comply with the local rule requiring that a separate statement of undisputed facts accompany a motion for summary judgment is insufficient to warrant reversal in the absence of any showing of prejudice. See Lewis v. Holzman (In re Telemart Enters., Inc.), 524 F.2d 761, 766 (9th Cir. 1975).

AFFIRMED.
