One of the main arguments for the trade groups and ISPs that have filed six-yes, six-lawsuits against the U.S. Federal Communications Commission's net neutrality rules is that the agency violated a 69-year-old administrative procedure law in crafting the new regulations. The two ISPs and four trade groups filing lawsuits in recent days have challenged the FCC's decision-as part of the new net neutrality rules-to reclassify broadband as a regulated, common-carrier service, instead of its long-standing classification of broadband as a lightly regulated information service.
