Andrew Maxwell Parker, federal prisoner # 08987-424, appeals a third amended *245 judgment, which modified, in his favor, periods of supervised release imposed pursuant to his pleading guilty to, inter alia, counts 27 and 28 of his indictment. Parker raises no issue, however, with respect to that amended judgment. E.g., Brinkmann v. Dallas Cnty. Deputy Sheriff Abner, 813 F.2d 744, 748 (5th Cir. 1987) (failure to brief issues relating to judgment appealed from equivalent to not appealing at all). He instead raises claims rejected by the district court in denying his related 28 U.S.C. § 2255 motion. (Although the § 2255 motion was denied, it prompted the judgment’s being amended.)

Parker, however, has not obtained the requisite certificate of appealability (COA) authorizing an appeal of those claims. The COA requirement is jurisdictional. 28 U.S.C. § 2253(c); Miller-El v. Cockrell, 537 U.S. 322, 336, 123 S.Ct. 1029, 154 L.Ed.2d 931 (2003).

On the other hand, Parker has an appeal pending (case number 12-50628) from the denial of his § 2255 motion. The district court denied a COA. He may seek a COA from this court for that appeal.

DISMISSED.
