What the signed record shows
The proof is a signed, tamper-evident record. Anyone can check it, without an account, and nothing has to leave the building to make it. Evidence, not a promise.
Where this stands. The law takes effect on 1 January 2027, and the Attorney General must adopt implementing rules before that date. On 11 August 2026 the Colorado Department of Law filed proposed ADMT and Chatbot Safety Rules covering SB 26-189 and HB 26-1263 together. It released an interim draft on 6 October 2026 and a Regulatory Analysis on 21 October 2026, and held the formal rulemaking hearing on 26 October 2026. The comment period closed at 11:59 p.m. MST that day, and the final rules are being drafted from the comments received. SB 26-189 repeals and replaces SB 24-205, whose own enforcement remains stayed under a joint-motion order while litigation continues.
What it means. The comment window has closed. The next dates are the final rules and the 1 January 2027 effective date.
