                  Appeal from the United States District Court
                      for the Middle District of Florida
                       _________________________

                                 (May 24, 2010)

Before CARNES, BARKETT and ANDERSON, Circuit Judges.

PER CURIAM:

     Zackery Bivens, through counsel, appeals the district court’s denial of his
motion for a sentence reduction, pursuant to 18 U.S.C. § 3582(c)(2). On appeal, he

argues that: (1) the district court erred in denying his § 3582(c)(2) motion after

finding that he was ineligible for a sentence reduction under Amendment 706

because he was sentenced as a career offender; and (2) the sentencing disparity that

exists between crack cocaine and powder cocaine offenses violated his equal

protection and due process rights.

      Bivens acknowledges that United States v. Moore, 541 F.3d 1323 (11th Cir.

2008), held that career offenders are ineligible to receive a sentence reduction

under Amendment 706. Nonetheless, he urges us to reconsider our Moore

decision. However, only the en banc court can reconsider our precedent.

Accordingly, Bivens is not entitled to relief.

      Bivens next argues, for the first time on appeal, that the Sentencing

Guidelines for crack cocaine offenses violates the Equal Protection and Due

Process Clauses because the disparity in punishments for crack cocaine and

powder cocaine offenses “is irrational and racially discriminatory.”

      When a party fails to raise an issue before the district court, we review the

issue for plain error. United States v. Jones, 289 F.3d 1260, 1265 (11th Cir. 2002).

Plain error occurs if (1) there was error, (2) that was plain, (3) that affected the

defendant’s substantial rights, and (4) that seriously affected the “fairness,



                                            2
integrity, or public reputation of judicial proceedings.” Id.

      It is unclear whether Bivens argues that his original sentence violates his

equal protection and due process rights. In any event, he may not raise a

constitutional challenge to his original sentence in a § 3582(c)(2) proceeding. See

United States v. Bravo, 203 F.3d 778, 782 (11th Cir. 2000) (declining to consider

defendant’s Eight Amendment claim because “such a collateral attack on [a]

sentence” should be brought pursuant to 28 U.S.C. § 2255 and not § 3582(c)(2)).

Nonetheless, we have held that the sentencing disparity between crack cocaine and

powder cocaine offenses does not violate the Equal Protection Clause. See United

States v. Butler, 102 F.3d 1191, 1194-95 (11th Cir. 1997) (holding that 100:1

sentencing disparity between crack cocaine and powder cocaine offenses does not

violation a defendant’s equal protection rights). We have likewise held that this

sentencing disparity does not violate the Due Process Clause. See United States v.

Hanna, 153 F.3d 1286, 1287-88 (11th Cir. 1998).

      AFFIRMED.
