AT&T Loses Bid to Temporarily Halt California's Enforcement of COLR Obligations
A federal judge denied AT&T’s preliminary injunction request, but allowed advocates, local governments, and a telecom group to enter the case
WASHINGTON, July 17, 2026 – A federal judge Thursday rejected an effort by AT&T to temporarily stop California regulators from requiring the company to provide basic telephone service.
AT&T had sought a preliminary injunction in its suit challenging the California Public Utilities Commission’s carrier of last resort rules. U.S. District Judge Linda Lopez of the Southern District of California denied AT&T’s request, allowing the rules to remain in effect while the case moves forward.
