This bill, designated as SB 3116, establishes restrictions on state and municipal cooperation with federal civil immigration enforcement. It asserts that state and local authorities are prohibited from voluntarily participating in civil immigration enforcement activities, while still allowing compliance with judicial warrants or court orders issued by a court of competent jurisdiction.

The bill introduces a new chapter, CHAPTER 161.1, which includes definitions for key terms such as "administrative warrant," "civil immigration detainer," "civil immigration enforcement," and "law enforcement agency." It outlines limitations on the use of state resources for civil immigration enforcement, stating that no state or local agency may enter into or renew agreements for civil immigration enforcement, processing, detention, housing, or removal, except as required by federal or state law or upon presentation of a valid judicial warrant or court order.

Furthermore, the bill restricts law enforcement agencies and officials from participating in or assisting immigration agents in civil immigration enforcement, providing nonconsensual access to individuals in custody for immigration enforcement interviews, transferring individuals to immigration agents, or disclosing non-public information for immigration enforcement purposes. It specifies that a law enforcement agency shall not detain or extend the detention of an individual solely for civil immigration enforcement without a judicial warrant or court order, and clarifies that a civil immigration detainer or administrative warrant does not constitute probable cause for continued detention under state law.

Individuals aggrieved by violations of this chapter may bring a civil action for declaratory and equitable relief, and prevailing plaintiffs are entitled to reasonable attorneys' fees and costs. The bill also includes a severability clause, ensuring that if any provision is held invalid, the remaining provisions will still be enforceable. The act will take effect upon passage.
