In a 6-3 decision led by Justice Clarence Thomas, the court overturned a federal court decision that would force cable companies to share their infrastructure with Internet service providers such as Brand X and EarthLink.

Specifically, the court focused on the question of whether a cable company provides "telecommunications services" or "information services." According to the Telecommunications Act, providers of information services are subject to much less stringent regulations than companies that provide telecommunications services.
