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:
UNITED STATES v. BASS
No. 01-1471.
Decided June 28, 2002
Per Curiam.
A federal grand jury sitting in the Eastern District of Michigan returned a second superseding indictment charging respondent with, inter alia, the intentional firearm killings of two individuals. The United States filed a notice of intent to seek the death penalty. Respondent, who is black, alleged that the Government had determined to seek the death penalty against him because of his race. He moved to dismiss the death penalty notice and, in the alternative, for discovery of information relating to the Government’s capital charging practices. The District Court granted the motion for discovery, and after the Government informed the court that it would not comply with the discovery order, the court dismissed the death penalty notice. A divided panel of the United States Court of Appeals for the Sixth Circuit affirmed the District Court’s discovery order. 266 F. 3d 532 (2001). We grant the petition for a writ of certiorari and now summarily reverse.
In United States v. Armstrong, 517 U. S. 456, 465 (1996), we held that a defendant who seeks discovery on a claim of selective prosecution must show some evidence of both discriminatory effect and discriminatory intent. We need go no further in the present case than consideration of the evidence supporting discriminatory effect. As to that, Armstrong says, that the defendant must make a “credible showing” that “similarly situated individuals of a different race were not prosecuted.” Id., at 465, 470. The Sixth Circuit concluded that respondent had made such a showing based on nationwide statistics demonstrating that “[tjhe United States charges blacks with a death-eligible offense more than twice as often as it charges whites” and that the United States enters into plea bargains more frequently with whites than it does with blacks. 266 F. 3d, at 538-539 (citing U. S. Dept. of Justice, The Federal Death Penalty System: A Statistical Survey (1988-2000), p. 2 (Sept. 12,2000)). Even assuming that the Armstrong requirement can be satisfied by a nationwide showing (as opposed to a showing regarding the record of the decisionmakers in respondent’s case), raw statistics regarding overall charges say nothing about charges brought against similarly situated defendants. And the statistics regarding plea bargains are even less relevant, since respondent was offered a plea bargain but declined it. See Pet. for Cert. 16. Under Armstrong, therefore, because respondent failed to submit relevant evidence that similarly situated persons were treated differently, he was not entitled to discovery.
The Sixth Circuit’s decision is contrary to Armstrong and threatens the “performance of a core executive constitutional function.” Armstrong, supra, at 465. For that reason, we reverse.
It is so ordered.
In January 1995, the Department of Justice (DOJ) instituted a policy, known as the death penalty protocol, that required the Attorney General to make the decision whether to seek the death penalty once a defendant had been charged with a capital-eligible offense. See Pet. for Cert. 3 (citing DOJ, United States Attorneys’ Manual § 9-10.010 et seq. (Sept. 1997)). The charging decision continued to be made by one of the 93 United States Attorneys throughout the country, but the protocol required that the United States Attorneys submit for review all cases in which they had charged a defendant with a capital-eligible offense. Ibid.
