¶1 Randy Johnson appeals the denial of his motion for summary judgment in this action under 42 U.S.C. § 1983 and Mississip *293 pi state law brought by the plaintiffs Jonathan P. New, Robert E. Stroupe, Michael P. Trouard, Scott M. Walle, and Brock L. Whitson. He argues that the district court erred by denying his summary judgment motion on the merits of his qualified immunity defense.
¶2 We must determine the basis of our jurisdiction, on our own motion, if necessary. Mosley v. Cozby, 813 F.2d 659, 660 (5th Cir.1987). “[Ojrders denying qualified immunity are immediately appealable only if they are predicated on conclusions of law, and not if a genuine issue of material fact precludes summary judgment on the question of qualified immunity.” Palmer v. Johnson, 193 F.3d 346, 351 (5th Cir.1999). Because genuine issues of material fact are disputed, precluding a determination that the appellant should enjoy qualified immunity, we lack jurisdiction to consider the instant appeal. The appeal is DISMISSED.
