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.

Per Curiam.
We noted probable jurisdiction in this case, 406 U. S. 956, to review the judgment of a three-judge district court, holding that Indiana’s system of administering unemployment insurance was in conflict with § 303 (a)(1) of the Social Security Act, 49 Stat. 626, as amended, 42 U. S. C. §503 (a)(1). Before the three-judge court entered its injunction, Indiana’s practice was to discontinue unemployment benefits upon a determination of ineligibility, that determination taking place without the benefit of a full hearing for the erstwhile beneficiary.
After several months of effort, however, the class representative in this litigation, Mrs. Burney, succeeded in obtaining a reversal of the initial determination of ineligibility. She has now received full retroactive compensation.
The full settlement of Mrs. Burney’s financial claim raises the question whether there continues to be a case or controversy in this lawsuit. Though the appellee purports to represent a class of all present and future recipients of unemployment insurance, there are no named representatives of the class except Mrs. Burney, who has been paid. Cf. Bailey v. Patterson, 369 U. S. 31, 32-33. Accordingly, the judgment is vacated and the case is remanded to the District Court to consider whether it has become moot.
It is so ordered.
The three-judge court was convened pursuant to 28 U. S. C. §§ 2281, 2284, to consider the prayer for an injunction against enforcement of the Indiana statute, Ind. Ann. Stat. § 52M542a (e) (Supp. 1970), on the grounds that it violated the appellee’s right to due process under the Fourteenth Amendment. The District Court did not reach this issue.
The District Court entered a temporary restraining order against the appellants on May 7,1971. Presumably, the appellee’s payments were then restored pending the outcome of her hearing before a referee, which took place, on July 1, 1971. On July 13, 1971, the referee affirmed the determination of ineligibility. Mrs. Burney then appealed to the Division Review Board. After the judgment and injunction were entered by the District Court, the Review Board reversed the referee and awarded payments to Mrs. Burney. This latter determination was unrelated to the injunction.
