Lawyers for the National Football League and its member teams are asking a federal judge to toss out all claims for monetary damages in a class action antitrust suit brought by satellite TV viewers who complained that the price of the “NFL Sunday Ticket” is illegally fixed.

The suit, which was filed in 1997, cleared a significant hurdle last year when the 3rd U.S. Circuit Court of Appeals greenlighted it to go forward, holding that professional football’s exemption from antitrust laws does not extend to satellite broadcasts.
