However, the Chicago authorities would eventually block these plans by requiring the NSPA to post a $350,000 public safety insurance bond and by banning political demonstrations in Marquette Park.
[9][10] While Collin filed a lawsuit against the City of Chicago for a violation of his first amendment rights, he realized that this case would get tied up in the courts for far longer than he was willing to wait to begin marching again.
[11] On October 4, 1976, Collin sent out letters to the park districts of the North Shore suburbs of Chicago, requesting permits for the NSPA to hold a white power demonstration.
[16] In addition to filing an injunction, the Village of Skokie passed three ordinances on May 2, 1977 in an attempt to prevent all future events that would be like the march which the NSPA had requested permission to stage.
[18][19] The two other ordinances prohibited the distribution of material containing hate speech and a required a $350,000 insurance bond to hold a demonstration.
[21] On March 20, 1977, Collin notified the Chief of Police and Park District of the NSPA's intentions to protest for their right to free speech on May 1.
On April 28, 1977, village attorney Schwartz filed suit in the Circuit Court of Cook County for an emergency injunction against the march to be held on May 1, 1977.
[5] On June 14, 1977, the Supreme Court ordered Illinois to hold a hearing on their ruling against the National Socialist Party of America, emphasizing that "if a State seeks to impose a restraint on First Amendment rights, it must provide strict procedural safeguards, including immediate appellate review.
[4] In the summer of 1978, in response to the Supreme Court's decision, some Holocaust survivors set up a museum on the Main Street of Skokie to commemorate those who had died in the concentration camps.
The Illinois Holocaust Museum and Education Center remains open today, having been moved to a new permanent location on Woods Drive in 2009.
the litigation left undecided, at the Supreme Court level, whether such older precedents as Beauharnais v. Illinois and Terminiello v. City of Chicago remain authoritative statements of how the First Amendment applies to provocative and intimidating hate speech expressing fascist or racist ideas.
[34] According to Nadine Strossen, the case was part of a gradual process in the 20th century where the Court strengthened First Amendment protections and narrowed down the application of earlier decisions which upheld restrictions of free speech, in part due to the realisation that the Illinois restrictions on Nazi "hate speech" were so broad they could have been equally used to prohibit Martin Luther King Jr. demonstrations in Skokie.
