State AI Regulation
Coverage from WION, Stanford Law School, and others
State AI regulation addresses how governments oversee automated systems used in decisions affecting areas such as employment, housing, credit, health care, education, and public services.
Colorado’s framework illustrates the policy and legal questions involved: its original Colorado Artificial Intelligence Act was challenged in court and replaced by SB 26-189, which centers on covered automated decision-making, consumer notice and explanations, correction, human review, and state enforcement. Connecticut statewide AI oversight forms a parallel state-law dimension. Together, these developments show how state approaches define regulated systems, assign duties to developers and deployers, and protect people affected by consequential decisions.
