Colorado SB 26-189: automated decision-making technology (replaces the Colorado AI Act, SB 24-205; effective 2027-01-01)

Developer documentation to deployers and notice of material updates; deployer notice of ADMT use; a plain-language explanation within 30 days of an adverse outcome; correction, human review and reconsideration; records kept at least three years. SB 26-189 (signed 2026-05-14) repealed and re-enacted SB 24-205, whose duty of care against algorithmic discrimination had been delayed to 2026-06-30 and whose enforcement a federal court had blocked
