California Attorney General Rob Bonta declared this week that federal immigration enforcement at state courthouses "violates the law," escalating his ongoing confrontation with ICE over courthouse arrests that California banned in 2017.

Bonta's comments follow a surge in Immigration and Customs Enforcement activity at California courthouses despite a state law explicitly prohibiting such arrests. Federal agents argue courthouses provide a safe, controlled environment for apprehending targets, while California officials say the practice violates state sovereignty and intimidates immigrant communities from accessing justice.

SB 54 Courthouse Protections

California's sanctuary state law, Senate Bill 54, requires the attorney general to issue model policies limiting ICE courthouse access. Every superior court in California must adopt either the attorney general's policy or an equivalent alternative. The law forbids civil immigration arrests in courthouses without a judicial warrant.

ICE under the Trump administration has ignored these restrictions, arguing that federal immigration enforcement authority supersedes state courthouse access policies. Officers continue detaining individuals at courthouses, citing operational safety and efficiency concerns.

Federal Preemption Argument

The Justice Department maintains that states cannot apply "generally applicable" regulations in ways that interfere with federal law enforcement. California lawyers counter that the state's courthouse policy applies equally to all law enforcement without discriminating against federal agents.

The dispute has already triggered litigation, with California attempting to rein in ICE courthouse activity through court orders. A Newsweek analysis found California's efforts largely failing, as federal judges have been reluctant to impose injunctions blocking ICE operations based on state policy.

Impact on Court Access

Immigrant rights advocates warn that ICE courthouse presence deters crime victims and witnesses from cooperating with local law enforcement or pursuing civil remedies like restraining orders. California Chief Justice Patricia Guerrero issued a statement defending courthouse access as fundamental to the rule of law.

The California State Bar is reviewing professional responsibility guidelines for attorneys forced to choose between client safety and court orders. Defense attorneys report clients afraid to appear for hearings, while prosecutors say witnesses increasingly refuse to testify in cases involving immigrant defendants or victims.

Bonta has issued alerts to housing providers and employers warning them of heightened ICE activity and reminding them of California tenant protections. The attorney general's office has held landlords accountable for violating California laws in multiple cities, extending his enforcement actions beyond the courthouse debate.
