UNITED STATES OF AMERICA, Plaintiff - Appellee, No. 08-3311 v. (D. Kansas) CARL MARSHALL, Defendant - Appellant. (D.C. No. 2:93-CR-20048-JWL-1)

ORDER AND JUDGMENT *

Before HARTZ , McKAY , and O’BRIEN , Circuit Judges.
Federal prisoner Carl Marshall appeals the denial of his motion under 18 U.S.C. § 3582(c)(2) for a reduction to his sentence. We have jurisdiction under 28 U.S.C. § 1291 and affirm. In 1993 Mr. Marshall was convicted in the United States District Court for the District of Kansas on a count of conspiracy to distribute crack cocaine and multiple counts of distribution of crack cocaine. He received a sentence of life-2- imprisonment. In 1997 the district court reduced his sentence to 400 months’ imprisonment based on a retroactive amendment to the sentencing guidelines. See USSG app. C, amend. 505 (Nov. 1, 1994); id . amend. 536 (Nov. 1, 1995) (making Amendment 505 retroactive). Mr. Marshall filed the § 3582(c)(2) motion at issue in June of 2008. He argued that Amendment 706, a retroactive amendment to the crack-cocaine guidelines, warranted a further reduction in his sentence. See id . supp. to app. C. amend. 706 (Nov. 1, 2007); id . supp. to app. C, amend. 713 (Mar. 3, 2008) (making Amendment 706 retroactive). But Amendment 706 did not lower Mr. Marshall’s offense level. As the district court observed, Mr. Marshall had been found responsible for 15 kilograms of crack cocaine at his original sentencing and thus his offense level was 38 (the highest level) both before and after the amendment. Because Amendment 706 had no effect on Mr. Marshall’s guideline range, the court concluded that he was not entitled to resentencing and denied his § 3582(c)(2) motion. The court relied on USSG § 1B1.10(a)(2), a Sentencing Commission policy statement providing that courts are “not authorized” to conduct resentencing under a retroactive amendment unless it has the “effect of lowering the defendant’s applicable guideline range.” On appeal Mr. Marshall advances two arguments, both of which this court has previously rejected. He first contends that § 1B1.10(a)(2) is advisory and that treating it otherwise violates the Sixth Amendment. Mr. Marshall admits that we-3- rejected this argument in United States v. Rhodes , 549 F.3d 833, 837–41 (10th Cir. 2008), and explains that he raises it here only to preserve the issue for (presumably) en banc or Supreme Court review. Mr. Marshall’s other contention is that § 1B1.10(a)(2) results from an unconstitutional delegation of Congress’s power to control the jurisdiction of the federal courts. See Panama Ref. Co. v. Ryan , 293 U.S. 388 (1935). We have rejected this argument. United States v. Dryden , __F. 3d__, No. 08-3310 (10th Cir. Apr. 30, 2009). We AFFIRM the judgment of the district court.
