California would restrict police agreements and federal officers’ state arrests

Federal criminal investigators and law enforcement officers would have limited authority to make arrests under California law. This applies to federal criminal investigators and law enforcement officers using arrest powers under California law. They may make arrests when a California agency requests their help with a joint task force or criminal investigation, or when probable cause points to an offense involving an immediate threat of great bodily injury that has just happened or is underway. They must meet training requirements before using these powers. The limits do not change their federal arrest powers while enforcing federal criminal law as part of their federal duties. The text gives no separate start date.

Deputized Bureau of Indian Affairs tribal officers could use specified arrest powers. This applies to deputized tribal law enforcement officers of the federal Bureau of Indian Affairs. They must complete required training before using these powers. They may act in specified situations under state or local law, when federal duties require incidental arrests, or when peace officers request help protecting tribal lands. Officers must meet the training requirements before using these arrest powers.

California law enforcement agencies would need written agreements with safeguards before entering covered law enforcement agreements. This applies to California police, sheriff, district attorney, probation, and other law enforcement agencies entering covered agreements. Unless federal or state law requires otherwise, the agreement must bar profiling, action based only on protected expression, certain crowd-control weapons against assemblies that do not meet legal requirements, and military equipment not authorized by law. The rule covers agreements with federal or out-of-state law enforcement agencies for criminal law enforcement, but not individual or informal communications. The specified immigration information exchanges remain allowed. Agreements in place on January 1, 2027, may remain in effect until July 1, 2027, but must include the required limits by then. New agreements may last up to four years and need a new written agreement to be renewed.

Some federal employees could serve as peace officers while enforcing California fish and game laws on federal property. This applies to eligible employees of the Fish and Wildlife Service, Forest Service, National Park Service other than park rangers, and Bureau of Land Management. Covered employees must meet training requirements and get written consent from the sheriff or police chief for the area. This authority applies to enforcing the Fish and Game Code on federal property and nearby streets, sidewalks, or property. The text gives no separate start date.
