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:
NELSON, aka ZIKEE v. UNITED STATES
No. 08-5657.
Decided January 26, 2009
Per Curiam.
Lawrence Nelson was convicted of one count of conspiracy to distribute and to possess with intent to distribute more than 50 grams of cocaine base. See 21 U. S. C. § 846. The District Court calculated Nelson’s sentencing range under the United States Sentencing Guidelines, and imposed a sentence of 360 months in prison (the bottom of the range). During sentencing, the judge explained that under Fourth Circuit precedent, “ ‘the Guidelines are considered presumptively reasonable,’ ” so that “ ‘unless there’s a good reason in the [statutory sentencing] factors ..., the Guideline sentence is the reasonable sentence.’” Pet. for Cert. 10.
The United States Court of Appeals for the Fourth Circuit affirmed Nelson’s conviction and sentence. United States v. Nelson, 237 Fed. Appx. 819 (2007) (per curiam). It noted that within-Guidelines sentences are presumptively reasonable, and rejected Nelson’s argument that the District Court’s reliance on that presumption was error. Id., at 821.
Nelson filed a petition for a writ of certiorari. We granted the petition, vacated the judgment, and remanded the case to the Fourth Circuit for further consideration in light of Rita v. United States, 551 U. S. 338 (2007). Nelson v. United States, 552 U. S. 1163 (2008).
On remand and without further briefing, the Fourth Circuit again affirmed the sentence. 276 Fed. Appx. 331 (2008) (per curiam). The court acknowledged that under Rita, while courts of appeals “may apply a presumption of reasonableness to a district court sentence that reflects a proper application of the Sentencing Guidelines,” 551 U. S., at 347, “the sentencing court does not enjoy the benefit of a legal presumption that the Guidelines sentence should apply,” id., at 351. Instead, the sentencing court must first calculate the Guidelines range, and then consider what sentence is appropriate for the individual defendant in light of the statutory sentencing factors, 18 U. S. C. § 3553(a), explaining any variance from the former with reference to the latter. Nonetheless, the Fourth Circuit upheld the sentence, finding that the District Court did not treat the Guidelines as “mandatory” but rather understood that they were only advisory. 276 Fed. Appx., at 333.
Nelson has again filed a petition for a writ of certiorari, reasserting, inter alia, essentially the same argument he made before us the first time: that the District Court’s statements clearly indicate that it impermissibly applied a presumption of reasonableness to his Guidelines range. The United States admits that the Fourth Circuit erred in rejecting that argument following our remand; we agree.
Our cases do not allow a sentencing court to presume that a sentence within the applicable Guidelines range is reasonable. In Rita we said as much, in fairly explicit terms: “We repeat that the presumption before us is an appellate court presumption. . . . [T]he sentencing court does not enjoy the benefit of a legal presumption that the Guidelines sentence should apply.” 551 U. S., at 351. And in Gall v. United States, 552 U. S. 38 (2007), we reiterated that district judges, in considering how the various statutory sentencing factors apply to an individual defendant, “may not presume that the Guidelines range is reasonable.” Id., at 50.
In this case, the Court of Appeals quoted the above language from Rita but affirmed the sentence anyway after finding that the District Judge did not treat the Guidelines as mandatory. That is true, but beside the point. The Guidelines are not only not mandatory on sentencing courts; they are also not to be presumed reasonable. We think it plain from the comments of the sentencing judge that he did apply a presumption of reasonableness to Nelson’s Guidelines range. Under our recent precedents, that constitutes error.
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.
