the Supreme Court in the 2010 case McDonald v. City of Chicago. Hosting of special events Byrne used special events, such as ChicagoFest, to revitalize Navy Pier and the downtown Chicago Theatre. ChicagoFest had first been held the year previous to her election. One of Byrne's first efforts as mayor had instead been an attempt to cancel future editions of the event. But, after facing complaints from citizens and unions, Byrne allowed the festival to continue as an annual event, and formally renamed it "Mayor Jane M. Byrne's ChicagoFest". Festivals inaugurated during her tenure included Taste of Chicago. Byrne held a number of smaller-scale events in neighborhoods across the city, titling them with the prefix "Mayor Byrne's". As mayor, Byrne was a strong supporter of the planned Chicago 1992 World's Fair. In 1980, Byrne announced that the city would host a Championship Auto Racing Teams "Indy Car" automobile race at Grant Park on the 4th of July weekend of the following year.

On November 11, 1981, Dan Goodwin, who had successfully climbed the Sears Tower the previous spring, battled for his life on the side of the John Hancock Center. William Blair, Chicago's fire commissioner, had ordered the Chicago Fire Department to stop Goodwin by directing a full-power fire hose at him and by using fire axes to break window glass in Goodwin's path. Mayor Byrne rushed to the scene and ordered the fire department to stand down. Then, through a smashed out 38th floor window, she told Goodwin, who was hanging from the building's side a floor below, that
