opinion: GREGORY et al. v. CITY OF CHICAGO.
  No. 60.
  Argued December 10, 1968.
  Decided March 10, 1969.
  Marshall Patner argued the cause for petitioners. With him on the briefs was Paul E. Goldstein.
  Raymond F. Simon argued the cause for respondent. With him on the brief were Marvin E. Aspen and Howard C. Goldman.
  Mr. Chief Justice Warren
  delivered the opinion of the Court.
  This is a simple case. Petitioners, accompanied by Chicago police and an assistant city attorney, marched in a peaceful and orderly procession from city hall to the mayor’s residence to press their claims for desegregation of the public schools. Having promised to cease singing at 8:30 p. m., the marchers did so. Although petitioners and the other demonstrators continued to march in a completely lawful fashion, the onlookers became unruly as the number of bystanders increased. Chicago police, to prevent what they regarded as an impending civil disorder, demanded that the demonstrators, upon pain of arrest, disperse. When this command was not obeyed, petitioners were arrested for disorderly conduct.
  Petitioners’ march, if peaceful and orderly, falls well within the sphere of conduct protected by the First Amendment. See Shuttlesworth v. City of Birmingham, post, p. 147; Brown v. Louisiana, 383 U. S. 131, 141-142 (1966) (prevailing opinion of Mr. Justice Fortas) ; Henry v. City of Rock Hill, 376 U. S. 376 (1964); Fields v. South Carolina, 375 U. S. 44 (1963), reversing 240 S. C. 366, 126 S. E. 2d 6 (1962). There is no evidence in this record that petitioners’ conduct was disorderly. Therefore, under the principle first established in Thompson v. City of Louisville, 362 U. S. 199 (1960), convictions so totally devoid of evidentiary support violate due process.
  The opinion of the Supreme Court of Illinois suggests that petitioners were convicted not for the manner in which they conducted their march but rather for their refusal to disperse when requested to do so by Chicago police. See 39 Ill. 2d 47, 60, 233 N. E. 2d 422, 429 (1968). However reasonable the police request may have been and however laudable the police motives, petitioners were charged and convicted for holding a demonstration, not for a refusal to obey a police officer. As we said in Garner v. Louisiana, 368 U. S. 157, 164 (1961): “[I]t is as much a denial of due process to send an accused to prison following conviction for a charge that was never made as it is to convict him upon a charge for which there is no evidence to support that conviction.” See also In re Oliver, 333 U. S. 257, 273 (1948).
  Finally, since the trial judge’s charge permitted the jury to convict for acts clearly entitled to First Amendment protection, Stromberg v. California, 283 U. S. 359 (1931), independently requires reversal of these convictions.
  The judgments are
  Reversed.
  The trial judge charged solely in terms of the Chicago ordinance. Neither the ordinance nor the charge defined disorderly conduct as the refusal to obey a police order.
instruction: 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.
