What follows is an opinion from the Supreme Court of the United States. Your task is to determine the bases on which the Supreme Court rested its decision with regard to the legal provision that the Court considered in the case. Consider "judicial review (national level)" if the majority determined the constitutionality of some action taken by some unit or official of the federal government, including an interstate compact. Consider "judicial review (state level)" if the majority determined the constitutionality of some action taken by some unit or official of a state or local government. Consider "statutory construction" for cases where the majority interpret a federal statute, treaty, or court rule; if the Court interprets a federal statute governing the powers or jurisdiction of a federal court; if the Court construes a state law as incompatible with a federal law; or if an administrative official interprets a federal statute. Do not consider "statutory construction" where an administrative agency or official acts "pursuant to" a statute, unless the Court interprets the statute to determine if administrative action is proper. Consider "interpretation of administrative regulation or rule, or executive order" if the majority treats federal administrative action in arriving at its decision.Consider "diversity jurisdiction" if the majority said in approximately so many words that under its diversity jurisdiction it is interpreting state law. Consider "federal common law" if the majority indicate that it used a judge-made "doctrine" or "rule; if the Court without more merely specifies the disposition the Court has made of the case and cites one or more of its own previously decided cases unless the citation is qualified by the word "see."; if the case concerns admiralty or maritime law, or some other aspect of the law of nations other than a treaty; if the case concerns the retroactive application of a constitutional provision or a previous decision of the Court; if the case concerns an exclusionary rule, the harmless error rule (though not the statute), the abstention doctrine, comity, res judicata, or collateral estoppel; or if the case concerns a "rule" or "doctrine" that is not specified as related to or connected with a constitutional or statutory provision. Consider "Supreme Court supervision of lower federal or state courts or original jurisdiction" otherwise (i.e., the residual code); for issues pertaining to non-statutorily based Judicial Power topics; for cases arising under the Court's original jurisdiction; in cases in which the Court denied or dismissed the petition for review or where the decision of a lower court is affirmed by a tie vote; or in workers' compensation litigation involving statutory interpretation and, in addition, a discussion of jury determination and/or the sufficiency of the evidence.

Opinion:
MOORE v. UNITED STATES
No. 07-10689.
Decided October 14, 2008
Per Curiam.
James Eric Moore was convicted of one count of possessing cocaine base with intent to distribute, a violation of 21 U. S. C. §§ 841(a)(1) and (b)(1). Given the quantity of crack cocaine, the presentence report calculated that Moore’s sentencing range under the United States Sentencing Guidelines was 151 to 188 months. At sentencing, Moore asked the District Court to impose a below-Guidelines sentence in light of our decision in United States v. Booker, 543 U. S. 220 (2005), and the Guidelines’ disparate treatment of similar amounts of crack and powder cocaine.
The District Court refused, saying:
“With regard to the crack and powder cocaine difference, that is the law. Pm applying the law as it currently stands. If that is going to be changed, that is a congressional matter. Congress is the one who looks at the guidelines and decides whether or not they should be put in — in force.... It isn’t the judges. It’s the lawmakers, and I have taken an oath to apply the law, and that’s what I will do in this sentencing.” App. D to Pet. for Cert. 55-56.
The District Court sentenced Moore to 188 months of imprisonment and six years of supervised release.
Moore appealed, and the United States Court of Appeals for the Eighth Circuit affirmed his conviction and sentence. United States v. Moore, 470 F. 3d 767 (2006). In response to his claim that the District Court should have considered the crack/powder disparity, the Court of Appeals held that “the district court was correct in concluding that ‘neither Booker nor [18 U. S. C.] § 3553(a) authorizes district courts to reject’ the powder cocaine to crack cocaine quantity ratio mandated by Congress and reflected in the Guidelines.” Id., at 770 (quoting United States v. Spears, 469 F. 3d 1166, 1176 (CA8 2006) (en banc)). Moore filed a petition for certiorari with this Court. Pet. for Cert. in Moore v. United States, O. T. 2007, No. 06-9749.
While Moore’s certiorari petition was pending, this Court issued its opinion in Kimbrough v. United States, 552 U. S. 85 (2007), concluding that a judge “may consider the disparity between the Guidelines’ treatment of crack and powder cocaine offenses” when applying 18 U. S. C. § 3553(a), “even in a mine-run case.” 552 U. S., at 91, 110. We granted Moore’s petition, vacated the judgment, and remanded the case to the Eighth Circuit for further consideration in light of Kimbrough. Moore v. United States, 552 U. S. 1090 (2008).
On remand, without new briefing, the Eighth Circuit affirmed again. 518 F. 3d 577 (2008). This time, the Court of Appeals concluded that “[a]s there was then no circuit authority to the contrary, we presume the district court was aware that Booker granted it discretion to vary downward based upon the impact of the crack cocaine guidelines on this defendant, but elected not to exercise that discretion.” Id., at 580.
Proceeding pro se, Moore again petitioned for certiorari, arguing that the Eighth Circuit’s new characterization of the transcript is wrong, and that it is “clear that the district court thought judges had no discre[t]ion to reject” the Guidelines ratio. Pet. for Cert. 7. The United States agrees that the Eighth Circuit erred, see Brief for United States 9, and so do we.
When the District Court said that “[i]t isn’t the judges” but Congress that “looks at the [Guidelines and decides whether or not they should be put ... in force,” the court showed that it did not think it had the discretion later upheld by Kimbrough. App. D to Pet. for Cert. 56. The Eighth Circuit’s first decision recognized this, describing the District Court as “concluding” (correctly under Circuit precedent) that it was not “authorized] ... to reject” the crack/ powder disparity. Moore, supra, at 770 (internal quotation marks omitted). In light of the District Court’s comments at sentencing, the Court of Appeals should have remanded the case to the District Court for resentencing under Kimbrough. We express no views on how the District Court should exercise its discretion at resentencing.
The petition for certiorari and the motion for leave to proceed in forma pauperis are granted. The judgment of the Court of Appeals is reversed, and the case is remanded for further proceedings consistent with this opinion.
It is so ordered.
