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:
W. M. C. A., INC., et al. v. SIMON, SECRETARY OF STATE OF NEW YORK, et al.
No. 836.
Decided June 11, 1962.
Leonard, B. Sand and Max Gross for appellants.
Louis J. Lefkowitz, Attorney General of New York, Irving Galt, Assistant Solicitor General, George C. Mant-zoros and Gretchen W. Oberman, Assistant Attorneys General, Sheldon Raab, Deputy Assistant Attorney General, Leo A. Larkin, Benjamin Offner, Bertram Harnett and Francis J. Morgan for appellees.
Per Curiam.
On January 11, 1962, the three-judge District Court dismissed the complaint alleging violation of the Constitution of the United States by New York State’s constitutional and statutory provisions governing apportionment of State Senate and Assembly Districts. 202 F. Supp. 741. The three judges filed separate opinions, no two of which supported the judgment of dismissal on identical grounds. One opinion expressed the view that the action should be dismissed for failure to state a claim, want of justiciability, and want of equity. 202 F. Supp., at 742. A second opinion expressed the view that since the apportionment was not alleged to effect a discrimination against any particular racial or religious group, but merely a geographical discrimination, jurisdiction should be exercised, but only to dismiss. 202 F. Supp., at 754. A third opinion rested on the ground that the action was not justiciable and expressed no view on the merits. 202 F. Supp., at 755.
On March 26, 1962, we held in Baker v. Carr, 369 U. S. 186, that a justiciable federal constitutional cause of action is stated by a claim of arbitrary impairment of votes by means of invidiously discriminatory geographic classification. Our well-established practice of a remand for consideration in the light of a subsequent decision therefore applies. As in Scholle v. Hare, 369 U. S. 429, we believe that the court below should be the first to consider the merits of the federal constitutional claim, free from any doubts as to its justiciability and as to the merits of alleged arbitrary and invidious geographical discrimination. The judgment is vacated and the case is remanded for further consideration in the light of Baker v. Carr, supra.
The motions to substitute Paul R. Screvane in the place of Abe Stark, and Eugene H. Nickerson in the place of A. Holly Patterson, as parties appellee, are granted.
MR. Justice Frankfurter took no part in the consideration or decision of this case.
