The U.S. Supreme Court ruled today in favor of the cable provider, saying an $875 million antitrust lawsuit filed on behalf of many as 2 million Philadelphia-area customers could not proceed as a single class-action suit. In a 5-4 ruling, the justices overturned a lower court decision to certify the case as a class action, saying the customers did not provide a common method that could be used to determine monetary damages for each individual party to the lawsuit, proof that is required before the case can proceed as a class action. Justice Antonin Scalia wrote the opinion for the majority. The plaintiffs alleged that the company was monopolizing the Philadelphia market in an attempt to control the market and unfairly raise prices. Comcast has denied the allegations.
