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:
BOKULICH et al. v. JURY COMMISSION OF GREENE COUNTY et al.
No. 1255,
Misc.
Decided March 3, 1969.
Morton Stavis, Arthur Kinoy, William M. Kunstler, Donald A. Jelinek, and Alvin Bronstein for appellants.
MacDonald Gallion, Attorney General of Alabama, . and Robert P. Bradley, Assistant Attorney General, for appellees.
Per Curiam.
The motion of the appellants for leave to proceed in forma pauperis is granted.
Appellants, civil rights workers, were arrested on charges of grand larceny. Together with other persons who are not parties to this appeal, the appellants were plaintiffs in this suit before a three-judge court. The complaint charged that Negroes had been systematically excluded from the grand and petit juries in Greene County and that the all-white county jury commission was unconstitutionally constituted. It sought declaratory and injunctive relief against continued discrimination in the selection of juries, against statutes that allegedly authorized the discrimination, and against the State Governor’s practice of selecting only white jury commissioners for Greene County. The appellants sought also an injunction to prevent the grand jury of Greene County from considering the criminal charges against them.
The District Court held that Negroes had been systematically and purposely excluded from the jury rolls of Greene County, Alabama, and that this discriminatory exclusion violated the appellants’ rights to equal protection and due process. It issued an injunction against discriminatory exclusion of Negroes from jury service in Greene County, and it ordered the appellees to take prompt action to compile a jury list on a nondiscriminatory basis. The court refused, however, to prevent the grand jury from considering the criminal charges against the appellants. This appeal presents only the issue whether the District Court erred in so ruling.
We hold that the District Court did not abuse its discretion. The District Court was warranted in assuming that the constitutional defects of which the appellants complained might be promptly remedied by compliance with its order that juries be reconstituted on a nondiscriminatory basis. If they were not, and if the appellants were in fact indicted, the appellants could raise any objection to the composition of the jury as a defense to their prosecutions. In these circumstances the court could properly conclude that this was not one of “those exceptional cases which call for the interposition of a court of equity to prevent irreparable injury which is clear and imminent.” Douglas v. Jeannette, 319 U. S. 157, 163 (1943). Accordingly, we affirm that part of the District Court’s judgment that denied an injunction preventing the Greene County grand jury from considering criminal charges against the appellants.
In No. 908 the plaintiffs in the court below other than the appellants in the present case appeal from the District Court’s determinations that the challenged Alabama statutes are not unconstitutional and that the Greene County jury commission was not proved to have been illegally constituted. We have today noted probable jurisdiction of that appeal. 393 U. S. 1115.
We do not reach the issue whether 28 U. S. C. §2283 would bar the injunction sought even if irreparable injury had been shown. Cf. Dombrowski v. Pfister, 380 U. S. 479, 484, n. 2 (1965).
