Colorado Pauses Enforcement of AI Disclosure Law

Colorado Attorney General Philip Weiser has agreed to halt enforcement of a state law requiring companies to provide "clear and conspicuous notice" when using artificial intelligence, according to a notice filed in a lawsuit brought by xAI.

The pause allows state lawmakers time to complete rulemaking and consider whether to replace the measure entirely. The enforcement suspension was filed in the federal court case challenging the law's constitutionality.

What the Law Required

The Colorado statute mandated that businesses disclose their use of AI in a way that is immediately apparent to users. The requirement applied broadly across industries and use cases.

xAI, the AI company founded by Elon Musk, filed suit arguing the law was unconstitutional. The company's legal challenge prompted the attorney general's decision to pause enforcement.

Next Steps

Colorado lawmakers will now work on regulations to implement or modify the law. The rulemaking process gives the legislature an opportunity to refine the disclosure requirements or potentially repeal the measure.

The pause represents a shift from the state's initial approach to AI regulation. Other states have pursued similar disclosure rules, making Colorado's decision a closely watched test case for how such laws function in practice.
