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:
TAYLOR et al. v. LOUISIANA.
No. 773.
Decided June 4, 1962.
Carl Rachlin and Judith P. Vladeck for petitioners.
Jack P. F. Gremillion, Attorney General of Louisiana, and M. E. Culligan, Assistant Attorney General, for respondent.
Per Curiam.
Petitioners, six Negroes, were convicted of violating Louisiana’s breach-of-the-peace statute, La. Rev. Stat., 1950, § 14:103.1, and were given fines and jail terms by the state court. The Louisiana Supreme Court declined to review their convictions, and the case is here on petition for a writ of certiorari which we have granted.
Four of the six petitioners went into the waiting room customarily reserved for white people at the Trailways Bus Depot in Shreveport, Louisiana, in order to take a bus to Jackson, Mississippi. The Chief of Police of Shreveport approached the four and asked them why they were in the station. They told him they were interstate passengers and wished to purchase tickets and obtain travel information. The Chief told them they could do this in the colored waiting room and ordered them to move on. When the four refused to leave, stating again that they were interstate passengers and asserting their rights under federal law, they were ordered to leave or be arrested. The spokesman of the group then said, “We have no choice; go ahead and arrest us.” The police thereupon arrested the four of them. The other two petitioners were then arrested, while sitting nearby in the automobile which had brought the six to the bus station.
At the trial there was testimony that immediately upon petitioners’ entry into the waiting room many of the people therein became restless and that some onlookers climbed onto seats to get a better view. Nevertheless, respondent admits these persons moved on when ordered to do so by the police. There was no evidence of violence. The record shows that the petitioners were quiet, orderly, and polite. The trial court said, however, that the mere presence of Negroes in a white waiting room was likely to give rise to a breach of the peace. It held the mere presence of the Negroes in the waiting room, as part of a preconceived plan, was sufficient evidence of guilt. It accordingly held that the four had violated the state breach-of-the-peace statute and that the other two had counseled and procured the others to commit the crime.
Here, as in Garner v. Louisiana, 368 U. S. 157, the only evidence to support the charge was that petitioners were violating a custom that segregated people in waiting rooms according to their race, a practice not allowed in interstate transportation facilities by reason of federal law. Boynton v. Virginia, 364 U. S. 454, 459-460. And see Mayor & City Council of Baltimore v. Dawson, 350 U. S. 877 (public beaches); Holmes v. City of Atlanta, 350 U. S. 879 (municipal golf courses); Gayle v. Browder, 352 U. S. 903 (bus); New Orleans Park Assn. v. Detiege, 358 U. S. 54 (municipal golf course and park). The judgments of conviction must therefore be
Reversed.
Mr. Justice Harlan would grant certiorari and set the case for argument.
Mr. Justice Frankfurter took no part in the consideration or decision of this case.
In relevant part, §14:103.1 provides: "A. Whoever with intent to provoke a breach of the peace, or under circumstances such that a breach of the peace may be occasioned thereby: (1) crowds or congregates with others ... in or upon . . . any . . . public place or building . . . and who fails or refuses to disperse and move on, or disperse or move on, when ordered so to do by any law enforcement officer of any municipality ... in which such act or acts are committed, or by any law enforcement officer of the state of Louisiana . .. shall be guilty of disturbing the peace.”
“That there exists a serious and difficult problem arising from a feeling of race hostility which the law is powerless to control, and to which it must give a measure of consideration, may be freely admitted. But its solution cannot be promoted by depriving citizens of their constitutional rights and privileges.” Buchanan v. Warley, 245 U. S. 60, 80-81.
