Major U.S. firms representing internet and cable associations filed suit Wednesday to stop California from implementing a sweeping new net neutrality law that provides the strongest internet access protections in the country.

Attorneys from Kellogg, Hansen, Todd, Figel & Frederick; Molo Lamken; Lewis & Llewellyn; and Latham & Watkins filed the 31-page complaint in the U.S. District Court for the Eastern District of California on behalf of the American Cable Association, CTIA – The Wireless Association and other trade groups that are opposed to the state’s California Internet Consumer Protection and Net Neutrality Act.
