Ronald Coleman, Louisiana prisoner # 119449, applied for federal habeas corpus relief, invoking 28 U.S.C. § 2241 and challenging his sentence. Before ruling on the merits of the application, the district court issued an order construing the petition as arising under 28 U.S.C. § 2254 and transferring the case to another section within the court. Coleman appealed to this court from the denial of his motion for reconsideration of the order construing his petition as arising under § 2254; he moves this court for a certificate of appealability (“COA”) to appeal the ruling on this interlocutory issue.

“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 order denying Coleman’s motion to reconsider the order construing his petition as arising under § 2254 and transferring the case to another section of the district court is a nonappealable interlocutory order. See 28 U.S.C. §§ 1291, 1292(a), (b); Brinar v. Williamson, 245 F.3d 515, 516-18 (5th Cir. 2001); Thomas v. Scott, 47 F.3d 713, 714-16 (5th Cir. 1995). This court is without jurisdiction to consider Coleman’s request for a COA. Accordingly, the motion for a COA is denied, and the appeal is dismissed for lack of jurisdiction.
