Provides that certain international organizations shall have no jurisdiction in this state and creates the "No Shari'a Act" regarding enforcement of certain foreign laws in this state

HB 3338 prohibits Missouri courts and state agencies from enforcing rules or mandates from international organizations (like the UN or World Health Organization) or foreign laws that violate fundamental rights. It specifically voids court decisions, contracts, or arbitration rulings that rely on Shari'a law or other foreign legal systems in areas like marriage, custody, or inheritance if they conflict with constitutional rights. The law defines "fundamental rights" as those protected by Missouri and U.S. constitutions, including due process, free speech, and religious freedom. It does not apply to religious organizations' internal matters, voluntary corporate agreements, or federal treaties.
