Immigration enforcement: prohibitions on access, sharing information, and law enforcement collaboration.
Summary
Existing law, the California Values Act, generally prohibits California law enforcement agencies from investigating, interrogating, detaining, detecting, or arresting persons for immigration enforcement purposes. Existing law provides certain limited exceptions to this prohibition, including transfers of persons pursuant to a judicial warrant and providing certain information to federal authorities regarding serious and violent felons in custody. This bill would prohibit California law enforcement agencies from collaborating with, or providing any information in writing, verbally, on in any other manner to, immigration authorities regarding proposed or currently underway immigration enforcement actions when the actions could be or are taking place within a radius of one mile of any childcare or daycare facility, religious institution, place of worship, hospital, or medical office. To the extent this bill would impose additional duties on local law enforcement agencies or officials, the bill would impose a state-mandated local program. The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill would provide that, if the Commission on State Mandates determines that the bill contains costs mandated by the state, reimbursement for those costs shall be made pursuant to the statutory provisions noted above. This bill would declare that it is to take effect immediately as an urgency statute.
