A California city voted to criminalize “aiding” and “abetting” homeless camps Tuesday – an unusual move that advocates say could stifle aid to help for people who need it.

The action by the city of Fremont, California, comes after a Supreme Court ruling in June that emboldened communities across the country to limit protections for people without homes. The court’s decision in Grants Pass, Oregon v. Johnson lets cities ban homeless residents from sleeping outside, even when a community lacks indoor shelter beds.

A controversial homeless camping ban has passed in Fremont, California, despite hundreds of people voicing their concerns during a city council meeting on Tuesday.
