The U.S. Department of Justice filed to intervene in a lawsuit brought by artificial intelligence company xAI that challenges a new Colorado law prohibiting “algorithmic discrimination.” The Department argues the statute violates the Equal Protection Clause of the Fourteenth Amendment. The Colorado law requires certain AI “developers” and “deployers” to meet disclosure, reporting, and prevention requirements for algorithmic products used in services such as mortgage lending, student admissions, and job-candidate selection. The Justice Department’s filing focuses on requirements to prevent unintentional disparate impact based on protected characteristics such as race and sex, and on an explicit carveout that exempts liability for discriminatory algorithms designed to advance “diversity” or “redress historic discrimination.” xAI filed its lawsuit on April 9, and the Justice Department’s intervention would position the federal government to participate directly in the case challenging Colorado SB24-205.
