Huntington Beach sued claiming that the state's law interfered with its authority to enforce local laws. An Orange County judge ruled for the city, saying municipalities with their own charters have a greater degree of autonomy.
California's attorney general also appealed the ruling last year. The state passed the law to protect immigrants from the Trump administration's push to ramp up deportations.
Residents in Los Alamitos have also been involved in litigation related to the issue.
A new report from UC Irvine accuses the Orange County Sheriff's Department of deliberately ignoring the Sanctuary State law.
It says deputies continue to turn over illegal immigrants to the Feds despite the law ..which is designed to limit cooperation with ICE.
The report's author Annie Lai, of the UCI Immigrant Rights clinic, tells KNX that deputies are going out of their way to skirt the new rules.
The OC Sheriff's department says it complies with the law.
One of the other agencies accused of flouting the law is the Laguna Beach police department.
