Colorado enacts SB 26-189, repealing and reenacting its covered-ADMT framework for consequential decisions
Colorado SB 26-189, signed May 14, 2026 (2026 Colorado Session Laws, chapter 131), repeals and reenacts with amendments part 17 of article 1 of title 6 of the Colorado Revised Statutes — the framework SB 24-205 created — and in doing so restates the duties attaching to "covered ADMT" under Colorado SB 26-189, automated decision-making technology used to materially influence a consequential decision. A "developer" is a person doing business in Colorado that makes a covered ADMT commercially available or intentionally modifies one to become covered; a "deployer" is a person doing business in Colorado that deploys one. Covered domains include education, employment, financial services, housing, insurance, health care, and essential government services. Under Colorado SB 26-189, a developer must document known limitations and harmful uses for deployers; a deployer must give point-of-interaction notice before using a covered ADMT to materially influence a consequential decision. Where a covered ADMT under Colorado SB 26-189 materially influences a consequential decision under that act resulting in an adverse outcome for a consumer, the deployer must provide, within 30 days after making the decision and without the consumer asking, a plain-language description of the decision and the covered ADMT's role in it, instructions for requesting further information, and an explanation of the consumer's rights. Separately, a consumer who experiences such an adverse outcome may request, and the deployer must then provide in response to that request, instructions for correcting inaccurate personal data used in the decision and an opportunity for meaningful human review and reconsideration of it, the latter to the extent commercially reasonable under Colorado SB 26-189. The Colorado Attorney General enforces exclusively under the Colorado Consumer Protection Act. Before an enforcement action, the Attorney General issues a notice of violation only where a cure is deemed possible by the Attorney General, opening a 60-day period to cure; where the Attorney General finds and can demonstrate a knowing or repeated violation, no cure period is required before penalties or other relief are sought. These cure provisions sunset January 1, 2030. Most duties apply to decisions made on or after January 1, 2027.
Where automated decision-making tools are used to make or substantially replace significant decisions about individuals, several state regimes — notably the CPPA regulations and Colorado's SB 26-189 — attach notice, opt-out, and assessment duties.
Where AI systems make or materially influence consequential decisions — employment, credit, housing, insurance, healthcare, or education — the Colorado-model developer-and-deployer regimes (SB 26-189) allocate documentation, notice, and review duties.
