Gregory and others were improperly convicted of disorderly conduct based on the disorderly behavior of bystanders to their First Amendment-protected demonstration.
Social activists, including comedianDick Gregory,protested against school segregation in Chicago, Illinois. Twelve years earlier, inBrown v. Board of Education,theU.S. Supreme Courtruledschool segregationunconstitutional.The protesters marched from Chicago's city hall to the mayor's residence in the white neighborhood of Bridgeport. After the march concluded, white bystanders began to act unruly and heckle the protesters; when they could not contain the hecklers' activity, police asked the protesters to disperse.[2]The protesters did not disperse and were consequently arrested, and subsequently convicted by a jury, of violating Chicago's disorderly conduct ordinance. The protesters appealed to the Illinois Supreme Court. That court upheld their conviction, holding that the protesters' refusal to obey the police order justified the convictions.[3]Aided by theACLU,the protesters appealed to the US Supreme Court.
The US Supreme Court, in a unanimous decision, overturned the conviction for several reasons:
"Petitioners were denied due process since there was no evidence to support their convictions"
"The convictions were for demonstrating, not for refusing to obey police orders."
"The trial judge's charge allowed the jury to convict for acts protected by the First Amendment.Stromberg v. California"
JusticeHugo Black,in a concurring opinion, argued that arresting demonstrators as a consequence of unruly behavior of bystanders would amount to a "heckler's veto."[4]
