The plaintiffs in this civil rights action filed a notice of appeal from an order of the district court dismissing fewer than all of the claims and parties. They seek to appeal the dismissal of the South Central Texas Regional Narcotics Task Force (“the Task Force”).

This court must examine the basis of its jurisdiction on its own motion if necessary. Mosley v. Cozby, 813 F.2d 659, 660 (5th Cir. 1987). This court has authority to hear appeals from “final decisions” under 28 U.S.C. § 1291. It also has jurisdiction under 28 U.S.C. § 1292 to hear appeals from interlocutory decisions, nonfinal judgments certified as final under Fed. R. Crv. P. 54(b), and some other nonfinal orders and judgments to which an exception applies. See Briargrove Shopping Ctr. Joint Venture v. Pilgrim Enters., 170 F.3d 536, 538 (5th Cir. 1999).

The plaintiffs argue that the district court’s order dismissing the Task Force is appealable under the collateral-order doc *260 trine. See Mitchell v. Forsyth, 472 U.S. 511, 524-25, 105 S.Ct. 2806, 86 L.Ed.2d 411 (1985). Because the district court’s order dismissing the Task Force “is capable of being fully and effectively reviewed after final judgment,” the collateral order doctrine is inapplicable, and this court lacks jurisdiction over the appeal. See Thompson v. Betts, 754 F.2d 1243, 1246 (5th Cir. 1985). Accordingly, the appeal is DISMISSED for lack of jurisdiction. The plaintiffs’ request for a stay of the appeal is DENIED.

APPEAL DISMISSED; STAY DENIED.
