Definition
A US state law, effective January 1 2027, that requires companies deploying AI to make consequential decisions—about employment, credit, healthcare, or housing—to notify affected individuals before and after those decisions, and to give them the right to appeal or seek human review. It replaces an earlier, broader 2024 law.
Why it matters
Colorado's law is the leading edge of US state AI regulation and is being watched as a template by other states. Any organisation using automated tools to make decisions that affect employees, customers, or job applicants in Colorado must build disclosure and appeal mechanisms into those systems before year-end 2026.
