Alanda Jabar Clayton, federal prisoner # 13570-064, appeals the district court’s denial of his 28 U.S.C. § 2241 petition alleging that his constitutional rights were violated when the Bureau of Prisons (“BOP”) denied him a one-year sentence reduction, pursuant to 18 U.S.C. § 3621(e), after initially informing him that he was eligible for such a reduction.

Clayton argues that the Supreme Court decision in Lopez v. Davis, 531 U.S. 230, 121 S.Ct. 714, 148 L.Ed.2d 635 (2001), was impermissibly applied retroactively to deprive him of eligibility for a one-year reduction in his sentence. Contrary to Clayton’s belief, Lopez did not create a new law that denied him eligibility for early release under 18 U.S.C. § 3621(e). Because Lopez merely declared permissible a regulation that had gone into effect prior to Clayton’s conviction, there is no retroactivity issue here.

Clayton argues that when his sentence was recalculated he acquired a liberty interest in early release and that the subsequent change in his eligibility status for early release violated his due process rights. His claims fail because there is no protected liberty interest in early release under 18 U.S.C. § 3621(e). See Rublee v. Fleming, 160 F.3d 213, 216 (5th Cir. 1998); Venegas v. Henman, 126 F.3d 760, 765 (5th Cir. 1997). Accordingly, the district court did not err in denying Clayton’s petition, and its judgment is AFFIRMED.
