The American Civil Liberties Union (ACLU) branch in Southern California has filed a lawsuit on behalf of the Black Lives Matter organization over the curfews in Los Angeles and San Bernadino.

The lawsuit “challenges the draconian curfews imposed throughout Southern California to crack down on widespread protests against systemic police violence towards Black people,” said the ACLU in a press release on Wednesday.

“The curfews’ extraordinary suppression of all political protest in the evening hours plainly violates the First Amendment to the US Constitution, and their blanket restrictions on movement outside working hours violate the Constitution’s protection of freedom of movement,” said the release.

The following defendants are listed in the lawsuit:

Eric Garcetti, mayor of Los Angeles.

Michel Moore, chief of Los Angeles Police Department.

Alex Villanueva, sheriff of Los Angeles County.

Kathryn Barger, Chair of the Los Angeles County Board of Supervisors.

Teri Ledoux, City Manager and Director of Emergency Services for San Bernardino.

Eric McBride, chief of San Bernardino Police Department.
