The bill establishes a new chapter in Title 10 RCW concerning tribal warrants, aiming to enhance cooperation between the state of Washington and federally recognized Indian tribes regarding public safety and justice. It recognizes the shared interest of the state and tribes in prosecuting individuals who violate either state or tribal laws. The legislation outlines the rights of defendants in tribal courts, ensuring they receive due process protections equivalent to those guaranteed by the U.S. Constitution. It also sets forth procedures for the recognition and execution of tribal arrest warrants by state peace officers, thereby facilitating the extradition of individuals who flee tribal jurisdiction.

Key provisions include definitions for "certified" and "noncertified" tribes, the process for extradition requests, and the responsibilities of state law enforcement when dealing with tribal warrants. The bill mandates that certified tribes' arrest warrants be treated with full faith and credit by state courts, while also establishing a framework for noncertified tribes to request extradition. Additionally, it creates an implementation work group to ensure effective execution of the act, which will begin its work in May 2024, with the full provisions of the act taking effect on July 1, 2025.
