This case was vacated and remanded to us by the United States Supreme Court for reconsideration in light of
Kimbrough v. United States,
— U.S. -,
On appeal, Tabor argues that the district court erred when it refused to consider that the crack cocaine Guidelines were “irrational” and resulted in “unfair and disparate sentences as compared to sentences for powder cocaine.”
Tabor,
I.
Like all versions prior to the recent amendments, the Guidelines in effect at Tabor’s sentencing advised that “a drug trafficker dealing in crack cocaine is subject to the same sentence as one dealing in 100 times more powder cocaine.”
Kimbrough v. United States,
— U.S. -,
These facts set the stage for
Kimbrough,
and in late 2007 the Supreme Court held that a district court may vary from the advisory sentencing range solely on the basis of its disagreement with the extent of the crack/powder disparity if it concludes that the “disparity yields a sentence ‘greater than necessary’ to achieve § 3553(a)’s purposes, even in a mine-run case.”
Id.
at 575 (quoting 18 U.S.C. § 3553(a)). Tabor’s sentencing occurred much earlier, however, on April 18, 2005.
United States v. Tabor,
In our original review of Tabor’s appeal, we did not address the correctness of this conclusion. Rather, we concluded that a sentence within the crack cocaine Guidelines was not inherently unreasonable.
Tabor,
In the intervening year, the Supreme Court has rejected the view that these concerns prohibit a district court from granting a downward variance on the basis of the crack/powder disparity. First,
Kimbrough
rejected the argument that Congress intended the 100-to-1 crack/powder ratio to form the basis for the crack cocaine Guidelines.
II.
With this history in mind, we now turn to considering Tabor’s appeal within the framework of appellate sentencing review. We review a defendant’s sentence for “both the procedural soundness of the district court’s decision and the substantive reasonableness of the sentence imposed.”
United States v. Merrival,
Such significant procedural error occurs if the district court fails to understand the scope of its authority and discretion at sentencing.
See United States v. Roberson,
We previously vacated the sentence in another case involving the same sentencing judge based on his statement that he did not have the power to vary downward on the basis of his disagreement with the 100-to-1 crack/powder cocaine ratio.
See United States v. Lee,
III.
Since we are remanding this case due to a procedural error, we need not consider the effect of the now-enacted retroactive Guideline amendments on Tabor’s advisory sentencing range. See USSG app. C, amend. 713 (Supp.2008); Sentencing Guidelines for United States Courts, 73 Fed.Reg. 217 (Jan. 2, 2008). Moreover, the propriety of such a remand is the subject of some disagreement in our circuit.
Compare United States v. Coleman,
Of course, we are not suggesting that the district court must impose a sentence lower than 151 months or even that the district court must impose a lower sentence at all. The core legal rule in Part IV of our prior panel opinion remains valid even in light of
Kimbrough:
A sentence is not unreasonable simply because the district court refuses to vary from the advisory sentencing range on the basis of the crack/powder disparity.
United States v. Moore,
IV.
For the reasons stated above, Tabor’s conviction is AFFIRMED pursuant to Parts I, II and III of our prior panel opinion,
United States v. Tabor,
