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:
ALVARADO v. UNITED STATES
No. 89-6985.
Decided June 25, 1990
Per Curiam.
At his criminal trial, petitioner claimed that the Government used certain peremptory challenges to remove black jurors solely on the grounds of race, contrary to Batson v. Kentucky, 476 U. S. 79 (1986). The District Court accepted the Government’s explanations for its challenges, and petitioner was convicted. He pursued his Batson claim in the Court of Appeals, claiming that the Government’s explanations were pretextual. The Government asserted that petitioner had not made out a prima facie Batson error and that it had race-neutral reasons for each challenge. The Court of Appeals did not rule on these competing claims, for it held that no appellate inquiry was required into the merits of a Batson claim if the jury finally chosen represented a fair cross section of the community, as did this jury. The conviction was affirmed.
Petitioner, seeking certiorari, urges that the Court of Appeals relied on an erroneous ground in rejecting the Batson claim. The United States agrees that the Court of Appeals erred in holding that as long as the petit jury chosen satisfied the Sixth Amendment’s fair-cross-section concept, it need not inquire into the claim that the prosecution had stricken jurors on purely racial grounds. That holding, the Government states, is contrary to Batson and is also discredited by our decision in Holland v. Illinois, 493 U. S. 474 (1990), which held that the fair-cross-section requirement of the Sixth Amendment did not apply to the petit jury and which was handed down after the Court of Appeals issued its opinion below. The Government urges us to deny certiorari, however, because petitioner failed to make out a prima facie case of intentional discrimination and because the reasons given for the challenges were race-neutral grounds for decision that the Court of Appeals did not reach.
When the Government has suggested that an error has been made by the court below, it is not unusual for us to grant certiorari, vacate the judgment below, and direct reconsideration in light of the representations made by the United States in this Court. See, e. g., Biddle v. United States, 484 U. S. 1054 (1988); Malone v. United States, 484 U. S. 919 (1987). Nor is it novel to do so in a case where error is conceded but it is suggested that there is another ground on which the decision below could be affirmed if the case were brought here. Indeed, a case decided earlier this Term presented such a situation and, without dissent, we vacated the judgment below for reconsideration in light of the position asserted by the Government in this Court. Chappell v. United States, 494 U. S. 1075 (1990). This is the appropriate course to follow in this case. If the judgment below rested on an improvident ground, as the Government suggests, the Court of Appeals should in the first instance pass on the adequacy of the Government’s reasons for exercising its peremptory challenges.
Consequently, the motion of petitioner for leave to proceed informa pauperis and the petition for a writ of certiorari are granted. The judgment is vacated, and the case is remanded to the United States Court of Appeals for the Second Circuit for further consideration in light of the position asserted by the Government in its brief filed May 21, 1990.
It is so ordered.
