This bill amends Chapter 33 of Title 18 of the Idaho Code to establish new provisions regarding machine guns and the enforcement of federal restrictions on their possession, manufacture, and transfer. It introduces a new section, 18-3328, which creates a contingent authorization framework that allows for the lawful possession and manufacture of machine guns in Idaho if federal restrictions, specifically 18 U.S.C. 922(o), are repealed or rendered unenforceable. The bill defines a "trigger event" that would activate this authorization, including congressional repeal, court decisions, or formal notices from the state attorney general regarding the enforcement of federal law.

Additionally, the bill adds another new section, 18-3329, which prohibits state agencies and officials from using state resources to enforce invalid federal restrictions on machine guns once a trigger event occurs. It clarifies that this does not prevent cooperation on matters that remain unlawful under state or federal law. The bill also includes a severability clause and declares an emergency, making it effective on July 1, 2026.
