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:
MASSACHUSETTS v. PAINTEN.
No. 37.
Argued October 18, 1967.
Decided January 15, 1968.
Elliot L. Richardson, Attorney General of Massachusetts, argued the cause for petitioner. With him on the briefs were Willie J. Davis and James B. Krasnoo, Assistant Attorneys General.
Louis M. Nordlinger argued the cause and filed a brief for respondent.
Anthony O. Amsterdam and Melvin L. Wulf filed a brief for the American Civil Liberties Union et ah, as amici curiae, urging affirmance.
Per Curiam.
In 1958 respondent was tried and convicted in Middle-sex Superior Court, Massachusetts, for armed robbery of a bank and related offenses. He appealed, and in 1961 his conviction was affirmed by the Supreme Judicial Court of Massachusetts, sub nom. Commonwealth v. Binkiewicz, 342 Mass. 740, 175 N. E. 2d 473.
Respondent eventually filed a petition for a writ of habeas corpus in the Federal District Court. Testimony was taken by the District Court on December 30, 1965. It ruled that respondent’s Fourth Amendment rights had been violated by the entry into his apartment, by his arrest, and by the search and seizure of certain articles in his apartment which were introduced in evidence against him. Accordingly, it set aside his conviction and ordered his release. Mapp v. Ohio, 367 U. S. 643 (1961). The Court of Appeals affirmed. We granted certiorari because of the importance of the constitutional issues presented.
At the time of respondent’s trial in 1958, Massachusetts did not have an exclusionary rule for evidence obtained by an illegal search or seizure, Commonwealth v. Wilkins, 243 Mass. 356, 138 N. E. 11 (1923); Commonwealth v. Spofford, 343 Mass. 703, 706, 180 N. E. 2d 673, 675 (1962), and the parties did not focus upon the issues now before us. The evidentiary hearing in 1965 took place almost eight years after the events.
After oral argument and study of the record, we have reached the conclusion that the record is not sufficiently clear and specific to permit decision of the important constitutional questions involved in this case. The writ is therefore dismissed as improvidently granted. Cf. Smith v. Mississippi, 373 U. S. 238 (1963).
Dismissed.
252 F. Supp. 851 (D. C. Mass. 1966).
368 F. 2d 142 (C. A. 1st Cir. 1966).
386 U. S. 931 (1967).
