Seven protesters and supporters have filed a suit accusing police and city officials of arresting or harassing demonstrators for exercising their First Amendment rights, even ticketing drivers who honk their horns in support.
At a hearing in Denver federal court Monday, they will ask a judge to order a halt to the alleged violations.
City attorneys deny the accusations and say the lawsuit doesn't provided any supporting facts.
At issue are city ordinances governing traffic, park hours and obstructions on sidewalks.
The lawsuit claims police are enforcing the ordinances selectively to quash the protests.
City lawyers filed a motion last week denying selective enforcement.
