The Federal Public Defender appointed to represent Oscar Omar Fuentes has moved for leave to withdraw and has filed a brief as required by Anders v. California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967). Fuentes has filed a response.

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). Article III, § 2, of the Constitution limits federal court jurisdiction to actual cases and controversies. Spencer v. Kemna, 523 U.S. 1, 7, 118 S.Ct. 978, 140 L.Ed.2d 43 (1998). The case-or-controversy requirement demands that “some concrete and continuing injury other than the now-ended incarceration or parole — some ‘collateral consequence’ of the conviction— must exist if the suit is to be maintained.” Id.

Fuentes has served the sentence that was imposed upon the revocation of his *313 supervised release. The order revoking Fuentes’s term of supervised release imposed no further term of supervised release. Accordingly, there is no case or controversy for this court to address, and the appeal is dismissed as moot. Counsel’s motion to withdraw is denied as unnecessary.

MOTION DENIED AS UNNECESSARY; APPEAL DISMISSED.
