Federal Court Stays Enforcement of Colorado's AI Act
On April 27, 2026, Chief Judge Daniel D. Domenico of the U.S. District Court for the District of Colorado stayed enforcement of the Colorado AI Act in X. AI LLC v. Weiser, No. 1:26-cv-01515. xAI had filed suit on April 9, 2026 raising First Amendment compelled-speech, Dormant Commerce Clause, due-process vagueness, and equal-protection claims, and the U.S. Department of Justice filed a complaint in intervention against the Act on April 24, 2026 — the first federal intervention in a state AI-law challenge. The stipulated order bars the Colorado Attorney General from initiating any investigation or enforcement of SB 24-205 (or legislation replacing or amending it) until 14 days after the court rules on xAI's forthcoming motion for a preliminary injunction. The Attorney General has stated it will not promulgate implementing rules or enforce the Act until the rulemaking process concludes.
