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 ordinance, which prohibits camping on all public property and allows prosecutors to criminally charge anyone “aiding” or “abetting” a homeless camp.

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

Fremont has enacted one of the most restrictive homeless encampment bans in California, sparking backlash from advocates and nonprofits who fear the ordinance could criminalize efforts to help those who are unhoused.

Outreach workers in the Bay Area city of Fremont worry the new ordinance could target them, despite assurances from the city.

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.
