State Government - As introduced, prohibits a nongovernmental or intergovernmental entity in this state from infringing upon or restricting private property rights without due process or an individual's constitutional rights by virtue of pursuing a policy recommendation originating from or traceable to the United Nations, a subsidiary entity thereof, or an international policymaking organization; makes it an offense for the state or an official or political subdivision in this state to infringe upon or restrict private property rights without due process or an individual's constitutional rights in pursuing United Nations or international policymaking organizational policy. - Amends TCA Section 4-1-422.

SB 1231 prohibits Tennessee state and local governments (including counties, cities, and school districts) from adopting or implementing policies that restrict private property rights without due process, specifically when those policies originate from or are traceable to the United Nations, its subsidiaries, or other international policymaking organizations like the World Health Organization or World Economic Forum. The bill explicitly targets policies such as the UN’s Agenda 21 (1992), the 2030 Sustainable Development Goals (2015), and net-zero emissions plans, banning state funding or agreements with entities promoting these initiatives. It allows individuals to sue governments for violations, with courts able to void noncompliant policies, award damages, and issue orders for compliance. Violations may also trigger criminal charges for officials under Tennessee’s "official oppression" statute.
