Amends TCA Section 4-1-422.

Tennessee SB1231 amends existing law to prohibit the infringement of individual constitutional rights and private property rights by policy recommendations from any international policymaking organization, broadening the scope from just the United Nations. The bill allows individuals to bring private causes of action against the state or political subdivisions for violations and mandates courts to issue writs of mandamus for compliance. Key provisions include defining "international policymaking organization," establishing penalties for officials who violate the bill, and granting the attorney general the authority to clarify violations.
