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:
FULLER v. ALASKA.
No. 249.
Decided October 28, 1968.
George Kaujmann for petitioner.
Per Curiam.
Petitioner was convicted of shooting with intent to kill or wound and was sentenced to 10 years in prison. Over petitioner’s objection that it was obtained in violation of § 605 of the Federal Communications Act, 48 Stat. 1103, 47 U. S. C. § 605, the prosecution introduced in evidence a telegram allegedly sent by petitioner to an accomplice. The Supreme Court of Alaska affirmed, holding that it did not need to decide whether § 605 had actually been violated since the evidence was in any event admissible in state trials under Schwartz v. Texas, 344 U. S. 199.
In Lee v. Florida, 392 U. S. 378, we overruled Schwartz v. Texas and held that evidence violative of § 605 is not admissible in state criminal trials. The decision of the Alaska Supreme Court cannot stand, therefore, if Lee is to be applied retroactively. We hold, however, that the exclusionary rule of Lee is to be given prospective application, and, accordingly, we affirm.
Prospective application of Lee is supported by all of the considerations outlined in Stovall v. Denno, 388 U. S. 293, 297. The purpose of Lee was in no sense to “enhance the reliability of the fact-finding process at trial.” Johnson v. New Jersey, 384 U. S. 719, 729. Like Mapp v. Ohio, 367 U. S. 643, Lee was designed to enforce the federal law. Linkletter v. Walker, 381 U. S. 618, 639. And evidence seized in violation of the federal statute is no less relevant and reliable than that seized in violation of the Fourth Amendment to the Constitution. Moreover, the States have justifiably relied upon the explicit holding of Schwartz that such evidence was admissible.
Retroactive application of Lee would overturn every state conviction obtained in good-faith reliance on Schwartz. Since this result is not required by the principle upon which Lee was decided, or necessary to accomplish its purpose, we hold that the exclusionary rule is to be applied only to trials in which the evidence is sought to be introduced after the date of our decision in Lee.
The petition for a writ of certiorari is granted, and the judgment of the Supreme Court of Alaska is affirmed.
These considerations were more recently applied in DeStefano v. Woods, 392 U. S. 631, 633, in which we concluded that the right to a jury trial in state criminal prosecutions under Duncan v. Louisiana, 391 U. S. 145, and Bloom v. Illinois, 391 U. S. 194, was prospective only.
Lee v. Florida, 392 U. S., at 386-387:
“We conclude, as we concluded in Elkins and in Mapp, that nothing short of mandatory exclusion of the illegal evidence will compel respect for the federal law ‘in the only effectively available way— by removing the incentive to disregard it.’ Elkins v. United States, 364 U. S., at 217.”
