Roxanne Zabner-Willis (“Zabner”) and two other pro se plaintiffs, Timothy C. Willis and Bob G. Willis, filed an action under the civil Rackeeter Influenced and Corrupt Organizations (“RICO”) Act, 18 U.S.C. § 1961, and a diversity action against defendant attorney James W. Gladden. The two actions were assigned the same district court case number, apparently because they were based on almost identical factual allegations.

On July 8, 2004, the district court issued an order severing the combined action into three individual actions, “one for each individual named plaintiff.” Zabner has now filed an interlocutory appeal from the July 8, 2004, order.

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). The July 8, 2004, order being appealed is not a final decision within the meaning of 28 U.S.C. § 1291 as it did not end the litigation on the merits. See Cunningham v. Hamilton County, Ohio, 527 U.S. 198, 204, 119 S.Ct. 1915, 144 L.Ed.2d 184 (1999). The order severing the case is not an immediately appealable collateral order. See Coopers & Lybrand v. Livesay, 437 U.S. 463, 468, 98 S.Ct. 2454, 57 L.Ed.2d 351 (1978); In re Lieb, 915 F.2d 180, 185 (5th Cir. 1990) (and decisions cited therein); 19 Moore’s Federal Practice § 202.11[llj; 15B Charles Alan Wright & Arthur P. Miller, Federal Practice and Procedure § 3914.20.

Accordingly, the appeal is DISMISSED for lack of jurisdiction.
