This bill amends Title 73 of the Idaho Code by adding a new Chapter 6, which establishes the state's public policy regarding the application of foreign laws. The chapter aims to protect Idaho citizens from foreign laws that may violate fundamental rights guaranteed by the U.S. Constitution or the Idaho Constitution, such as due process, freedom of religion, and rights related to privacy and marriage. It defines key terms, including "foreign law" and "religious organization," and outlines provisions for the unenforceability of foreign laws in court rulings, contracts, and jurisdictional matters if they do not align with these fundamental rights.

Additionally, the bill addresses the concept of forum non conveniens, stating that if a claim for this is made in Idaho and it could violate a fundamental right, the claim will be denied. The chapter includes specific applicability clauses, indicating that it does not apply to certain legal entities or contracts made prior to the act's effective date. It also clarifies that the provisions do not limit the free exercise of religion or interfere with ecclesiastical matters. The bill declares an emergency, making it effective on July 1, 2026.
