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:
RAY v. UNITED STATES
No. 86-281.
Argued April 28, 1987
Decided May 18, 1987
Joseph A. Connors III argued the cause for petitioner. With him on the brief was Matías Morin, Jr.
Deputy Solicitor General Bryson argued the cause for the United States. With him on the brief were Solicitor General Fried, Assistant Attorney General Weld, and Andrew J. Pincus.
Per Curiam.
Petitioner was found guilty of one count of conspiracy to possess cocaine with intent to distribute, and two counts of possession of cocaine with intent to distribute. He was sentenced to concurrent 7-year prison terms on all three counts, and to concurrent special parole terms of five years on the two possession counts. The Court of Appeals affirmed petitioner’s conspiracy conviction and one of his possession convictions. United States v. Sandoval, 791 F. 2d 929 (CA5 1986) (judg. order). Applying the so-called “concurrent sentence doctrine,” the court declined to review the second possession conviction because the sentences on the two possession counts were concurrent. We granted certiorari to review the role of the concurrent sentence doctrine in the federal courts. 479 U. S. 960 (1986).
It now appears, however, that petitioner is not in fact serving concurrent sentences. Title 18 U. S. C. § 3013 (1982 ed., Supp. Ill) provides that district courts shall assess a monetary charge “on any person convicted of an offense against the United States.” Pursuant to this section, the District Court imposed a $50 assessment on each count, in addition to the concurrent prison and parole terms, for a total of $150. Since petitioner’s liability to pay this total depends on the validity of each of his three convictions, the sentences are not concurrent. The judgment of the Court of Appeals is therefore vacated, and the cause is remanded to that court so that it may consider petitioner’s challenge to his second possession conviction.
It is so ordered.
