Davi Luks, a retired schoolteacher and longtime Contra Costa County resident, wanted to protest the human cost of the war in Gaza. So, he posted several signs and flags on his property in El Sobrante in the county’s unincorporated area.

County code enforcement fined him $4,300, claiming he had violated the county’s sign ordinance – a flagrant violation of his First Amendment rights.

Today, the ACLU of Northern California filed a federal lawsuit against Contra Costa County on behalf of Luks. It calls for the court to declare the ordinance unconstitutional. The suit also demands that county officials return Luks' unlawful $4,300 fine and remove the lien from his property.
