MEMORANDUM **

Reinhold V. Sommerstedt appeals pro se from the district court’s order holding him in civil contempt for failing to obey its orders requiring him to file a certification of compliance stating that he notified customers of the underlying summary judgment and injunction against him. We have jurisdiction under 28 U.S.C. § 1291. We review for an abuse of discretion a civil contempt order. Irwin v. Mascott, 370 F.3d 924, 931 (9th Cir. 2004). We affirm.

The district court did not abuse its discretion when it found Sommerstedt in contempt for his failure to comply with its orders requiring him to file a certification stating his compliance with the underlying injunction’s customer notification requirement. See id. (person subject to injunction generally may not contest its lawfulness by disobeying it).

Under the law of the case doctrine, we do not consider Sommerstedt’s challenges to the district court’s underlying summary judgment for the United States or to the resulting injunction’s customer notification requirement. See Leslie Salt Co. v. United States, 55 F.3d 1388, 1392 (9th Cir. 1995) (“Under law of the case doctrine, ... one panel of an appellate court will not reconsider matters resolved in a prior appeal to another panel in the same case.”).

AFFIRMED.
