Plaintiff-appellant AVE, Inc. (“AVE”) appeals the district court’s order granting the defendants-appellees’ motion to dismiss for lack of standing in AVE’s suit alleging that Comal County’s sexually oriented business regulations violate the United States Constitution. AVE argues that the district court erred by resolving factual ambiguities in favor of the defendants-appellees, the moving parties, contrary to the proper summary judgment standard. AVE also contends, in the alternative, that even if the district court properly determined the disputed facts, those facts do not establish that AVE lacks standing to sue.

We review the district court’s standing determination de novo. Pederson v. La. State Univ., 213 F.3d 858, 869 (5th Cir. 2000). A district court may hold a preliminary hearing to resolve factual disputes in *998 order to determine standing, especially when the jurisdictional challenge does not implicate the merits. Barrett Computer Servs., Inc. v. PDA Inc., 884 F.2d 214, 220 (5th Cir. 1989). Standing is a jurisdictional matter; therefore, the district court has greater latitude in resolving factual disputes than in a motion for summary judgment and it may decide factual ambiguities in favor of the moving party. Id. at 220. “If the district court resolves any factual disputes in making its jurisdictional findings, the facts expressly or impliedly found by the district court are accepted on appeal unless the findings are clearly erroneous.” Pederson, 213 F.3d at 869.

After carefully reviewing all submissions by the parties and the record in this case, we conclude that the district court’s factual findings were not clearly erroneous. In light of the facts determined by the district court, AVE failed to prove that it had standing. We therefore AFFIRM the order of the district court.

AFFIRMED.
