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:
HENRY et al. v. CITY OF ROCK HILL.
No. 826.
Decided April 6, 1964.
Jack Greenberg, Constance Baker Motley, Matthew J. Perry, Lincoln C. Jenkins, Jr., Donald James Sampson and Willie T. Smith, Jr. for petitioners.
Per Curiam.
When this case was last before us, we granted certiorari, vacated the judgment holding petitioners guilty of breach of the peace, and remanded the case to the Supreme Court of South Carolina “for further consideration in light of Edwards v. South Carolina, 372 U. S. 229.” 375 U. S. 6. That has been our practice in analogous situations where, not certain that the case was free from all obstacles to reversal on an intervening precedent, we remand the case to the state court for reconsideration. Daegele v. Kansas, 375 U. S. 1; Pickelsimer v. Wainwright, 375 U. S. 2; Newsome v. North Carolina, 375 U. S. 21; Shockey v. Illinois, 375 U. S. 22; Ausbie v. California, 375 U. S. 24; Herrera v. Heinze, 375 U. S. 26; Barnes v. North Carolina, 375 U. S. 28. The South Carolina Supreme Court examined Edwards and the later case of Fields v. South Carolina, 375 U. S. 44, found them not controlling, and reaffirmed the convictions. In its opinion on the remand in the present case, the South Carolina Supreme Court expressed doubt concerning the meaning and significance of our remand order, and it went on to explain why, in its view, the Edwards and the Fields cases were distinguishable. For those reasons, it is appropriate to add these words of explanation.
The South Carolina Supreme Court correctly concluded that our earlier remand did not amount to a final determination on the merits. That order did, however, indicate that we found Edwards sufficiently analogous and, perhaps, decisive to compel re-examination of the case.
We now think Edwards and Fields control the result here. As in those cases, the petitioners here, while at a place where the State’s law did not forbid them to be, were engaged in the “peaceful expression of unpopular views.” Edwards v. South Carolina, 372 U. S., at 237. They assembled in a peaceful, orderly fashion in front of the City Hall to protest segregation. They carried signs to that effect and they sang patriotic and religious songs. Although white onlookers assembled, no violence or threat of violence occurred and traffic was not disturbed. After 15 minutes of this, they were arrested for failure to disperse upon orders. Here, as in Edwards and Fields, petitioners “were convicted of an offense so generalized as to be, in the words of the South Carolina Supreme Court, ‘not susceptible of exact definition.’ ” Ibid. And here as there “they were convicted upon evidence which showed no more than that the opinions which they were peaceably expressing were sufficiently opposed to the views of the majority of the community to attract a crowd and necessitate police protection.” Ibid.
Edwards established that the “Fourteenth Amendment does not permit a State to make criminal the peaceful expression of unpopular views.” Ibid. As in Edwards, the South Carolina Supreme Court has here “defined a criminal offense so as to permit conviction of the petitioners if their speech 'stirred people to anger, invited public dispute, or brought about a condition of unrest. A conviction resting on any of those grounds may not stand.’ [Terminiello v. Chicago, 337 U. S. 1, 5.]” Id., at 238. Accordingly certiorari is granted and the judgment is reversed.
The South Carolina Supreme Court intimated that the rule of Edwards was designed to guide us in determining our review of state action. But Edwards states a rule based upon the Constitution of the United States which, under the Supremacy Clause, is binding upon state courts as well as upon federal courts.
