Unpublished opinions are not binding precedent in this circuit.

Cornelius Keith Smith seeks to appeal his criminal judgment entered in January 2011, his amended criminal judgment entered in January 2012, and the district court’s April 2016 order granting his motion for a sentence reduction under 18 U.S.C. § 3582(c)(2) (2012). On appeal, we confine our review to the issues raised in the Appellant’s brief. See 4th Cir. R. 34(b). Because Smith’s informal brief does not address the April 2016 order, Smith has forfeited appellate review of this order. See Jackson v. Lightsey, 775 F.3d 170, 177 (4th Cir. 2014) (“The informal brief is an important document; under Fourth Circuit rules, our review is limited to issues preserved in that brief.”). * In addition, because Smith has already appealed the January 2011 and January 2012 judgments, see United States v. Smith, 498 Fed.Appx. 359 (4th Cir. 2012); United States v. Smith, 450 Fed. Appx. 306 (4th Cir. 2011), the appeals from these judgments are duplicative.

Accordingly, we affirm the district court’s April 2016 order and dismiss as duplicative the appeals from the January 2011 and January 2012 judgments. 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.
