Creates a new section in chapter 4.24 RCW establishing a private cause of action for persons whose U.S. Constitutional rights are allegedly deprived during "civil immigration enforcement" by anyone acting under color of law. "Civil immigration enforcement" is defined to include investigation, questioning, detention, transfer, arrest, or removal for the purpose of enforcing civil immigration law, and "color of law" includes federal, state, territorial, and D.C. statutes, ordinances, regulations, customs, or usages. The new provision allows relief by action at law, suit in equity, or other proper proceedings and requires such actions to be commenced within two years after the cause of action accrues. The bill makes several procedural and remedial rules: courts may, in their discretion, award prevailing plaintiffs reasonable attorneys' fees (including expert fees as part of attorneys' fees); judicial officers acting in a judicial capacity are immune from injunctive relief unless a declaratory decree was violated or declaratory relief was unavailable, and are not liable for costs including attorneys' fees unless the action was clearly in excess of their jurisdiction. Defendants may assert absolute or qualified immunity to the same extent available under 42 U.S.C. §1983, and any other sovereign immunity defenses are preserved. The text includes severability language and provides that any provision conflicting with federal requirements tied to federal funds is inoperative to the extent of the conflict for affected agencies; affected agencies' rules must meet necessary federal conditions. The act is declared an emergency measure and takes effect immediately upon enactment. The exact RCW section number added and any legislative history or fiscal impacts are not provided in the extracted text.

If enacted, people who say their constitutional rights were violated during civil immigration enforcement are likely to bring more lawsuits against the officers and entities acting under color of law, and those suits must be filed within two years. Successful plaintiffs can recover attorneys’ fees and courts may include expert fees, which raises the potential financial exposure for defendants, though defendants can still raise the same absolute or qualified immunity defenses available under federal law and sovereign immunity is preserved; judicial officers will generally be shielded from injunctions and fee liability unless they clearly exceeded their jurisdiction. The groups most affected are federal, state and local officials and agencies involved in civil immigration enforcement and the agencies that fund or oversee them: they may face higher litigation risk and related costs, and may need to review policies, training, or procedures to limit exposures. Agencies that rely on federal funding should note that any part of this law that conflicts with federal conditions would not apply to them and must adopt rules that meet federal requirements; the bill takes effect immediately, and some implementation details and fiscal impacts are not provided in the text.
