PER CURIAM.
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 plaintiff, Citizen D. “K” Stewart, has filed a notice of appeal and motion to proceed on appeal in forma pauperis (IFP) from the district court’s February 4, 2003, order. In that order, the district court denied Stewart’s motion for relief from judgment or order, which challenged the district court’s January 22, 2003, order denying service by the United States Marshal without prepayment of fees.
Federal appellate courts have jurisdiction over appeals only from (1) final orders, 28 U.S.C. § 1291; (2) orders that are deemed final due to jurisprudential exception or which can be properly certified as final pursuant to Fed. R. Civ. P. 54(b); and (3) interlocutory orders that fall into specific classes, 28 U.S.C. § 1292(a), or which can be properly certified for appeal by the district court, 28 U.S.C. § 1292(b). Askanase v. Livingwell, Inc., 981 F.2d 807, 809-10 (5th Cir.1993); Dardar v. Lafourche Realty Co., 849 F.2d 955, 957 (5th Cir. 1988). The district court’s February 4, 2003, order is not final or otherwise appealable. Accordingly, the appeal is DISMISSED for lack of appellate jurisdiction. Stewart’s motion for IFP is DENIED.
Pursuant to 5th Cir. R. 47.5, the court has determined that this opinion should not be published and is not precedent except under the limited circumstances set forth in 5th Cir. R. 47.5.4.
