Nudists stripped down and shouted anti-corporate slogans when a second approval for the nude ban passed in City Hall.

You've got to admire their tenacity.

In January, a judge dismissed a lawsuit filed by San Francisco nudists that claimed their First Amendment right to free speech was violated by Supervisor Scott Wiener’s nudity ban. But the decision didn’t deter nudists from their fight to strip down in The City – they’ve filed an amended suit and are staging a protest and ‘body freedom parade’ this Saturday.

The protest is scheduled at noon on July 20, in front of City Hall. The parade will follow, but there’s no word on what route it will take. Under the ban, nudists face a $100 fine for their first offense, with increases for additional infractions.

The amended lawsuit includes five plaintiffs: Russell “Trey” Allen, Mitch Hightower, George Davis, Russell Mills, and Oxane “Gypsy” Taub. Although they initially sued The City for alleged free speech violations, they’ve now taken a different approach. The new suit alleges that the nudity ban has been enforced against them in a discriminatory fashion.

The lawsuit states that several plaintiffs were arrested for baring it all at a rally on February 1, and the others were arrested during a nude dance on February 27. However, plaintiffs were not arrested when they participated in nude activities led by other organizations, leading them to believe that they are being targeted by The City.
