## Federal Magistrate Grants Stay in Colorado AI Law Challenge

A federal magistrate judge in Denver halted enforcement of Colorado Senate Bill 24-205 on April 27, 2026, after xAI LLC filed a constitutional challenge and the U.S. Department of Justice intervened in the case [Gibson Dunn](https://www.gibsondunn.com/dei-task-force-update-june-8-2026/). The stay prevents the state from enforcing the AI antidiscrimination law while litigation proceeds in the U.S. District Court for the District of Colorado [Affirmity](https://www.affirmity.com/blog/colorado-ai-discrimination-enforcement-paused-after-xai-court-challenge/).

The court granted the parties' motion to stay proceedings, finding that doing so would "avoid burdening the parties with the costs of litigating, promotes judicial economy and efficiency, does not negatively impact nonparties, and is in the public interest." The magistrate's order applies to enforcement of SB 24-205 and any legislation replacing or amending it [Affirmity](https://www.affirmity.com/blog/colorado-ai-discrimination-enforcement-paused-after-xai-court-challenge/).

xAI filed the federal lawsuit on April 9, 2026, challenging SB 24-205 on constitutional grounds, and the DOJ filed to intervene as a plaintiff on April 24, 2026 [Gibson Dunn](https://www.gibsondunn.com/dei-task-force-update-june-8-2026/). The case is docketed as *X.AI LLC v. Philip J. Weiser*, No. 1:26-cv-01515 (D. Colo. 2026), with Colorado Attorney General Philip J. Weiser named as defendant.

## DOJ's Equal Protection Challenge

The Department of Justice argued that SB 24-205 violates the **Equal Protection Clause of the 14th Amendment** because the law requires AI developers to prevent unintentional disparate impact based on protected characteristics such as race and sex [Telehealth.org](https://telehealth.org/news/doj-joins-lawsuit-to-block-cos-ai-antidiscrimination-law-from-taking-effect-june-2026/). This marked the first time the federal government sought to invalidate a state AI law through court action [Gibson Dunn](https://www.gibsondunn.com/dei-task-force-update-june-8-2026/).

Colorado had originally set SB 24-205 to take effect January 1, 2027, but regulatory deadlines were extended to June 30, 2026 before the litigation began, increasing pressure for a rapid judicial resolution. The stay prevents enforcement until the court rules on xAI's preliminary-injunction motion.

## Significance for State AI Regulation

The stay signals potential constitutional vulnerability in state-level AI antidiscrimination statutes and underscores federal concern about state regulations that impose disparate-impact liability on AI systems. The case is expected to clarify whether states can mandate protected-class impact testing before systems are deployed.
