Daryl W. Smith seeks to appeal the 18-month term of imprisonment imposed upon the revocation of his supervised release. Counsel has filed a brief pursuant to Anders v. California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967), questioning the reasonableness of Smiths sentence but stating that there are no meritorious issues for appeal. Although advised of his right to file a supplemental pro se brief, Smith has not done so. During the pendency of this appeal, Smith was released from federal custody.
To maintain our subject matter jurisdiction over an appeal, “an actual controversy must be extant at all stages of review, not merely at the time the [appeal] is filed.” Arizonans for Official English v. Arizona, 520 U.S. 43, 67, 117 S.Ct. 1055, 137 L.Ed.2d 170 (1997) (internal quotation marks omitted). “When a case or controversy ceases to exist—either due to a change in the facts or the law—the litigation is moot, and the courts subject matter jurisdiction ceases to exist also.” Porter v. Clarke, 852 F.3d 358, 363 (4th Cir. 2017) (internal quotation marks omitted). “Because mootness is jurisdictional, we can and must consider it even if neither party has raised it.” United States v. Ketter, 908 F.3d 61, 65 (4th Cir. 2018).
Smith already has served his prison term and faces no further term of supervised release. Because the record suggests no collateral consequences from his expired prison term, there is no longer a live controversy regarding the length of his sentence. Smiths challenge to his revocation sentence is therefore moot. See United States v. Hardy, 545 F.3d 280, 283-85 (4th Cir. 2008).
Accordingly, we dismiss the appeal for lack of jurisdiction. In accordance with Anders, we have reviewed the entire record in this case and have found no meritorious grounds for appeal. This court requires that counsel inform Smith, in writing, of the right to petition the Supreme Court of the United States for further review. If Smith requests that a petition be filed, but counsel believes that such a petition would be frivolous, then counsel may move in this court for leave to withdraw from representation. Counsels motion must state that a copy thereof was served on Smith. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before this court and argument would not aid the decisional process.
