If you were arrested in Newport Beach, Costa Mesa, Laguna Beach, Dana Point, Aliso Viejo, Laguna Niguel, Laguna Woods, or parts of Irvine, your case will likely be scheduled at the Harbor Justice Center, located at 4601 Jamboree Road, Newport Beach, CA 92660.
Harbor Justice Center serves as the primary criminal courthouse for much of coastal and south-central Orange County. It handles a high volume of DUI cases, traffic-related crimes, and misdemeanor prosecutions, as well as select felonies from the region. The courthouse is well known for its fast-paced calendars and a prosecutorial focus on traffic safety and alcohol-related offenses.

We appear here regularly, understand the expectations of the local judges, and know how to challenge the methods used by city police departments and the California Highway Patrol in this region.
