A Catholic broadcasting company has filed a multimillion-dollar lawsuit against one of D.C.’s biggest business law firms, alleging that its lawyers botched a television licensing deal, costing the company untold millions.

The North American Catholic Educational Programming Foundation Inc. says that Womble Carlyle Sandridge & Rice and its former partner, Howard J. Barr, blew the deadline for filing an appeal with the Federal Communications Commission, which “injured” the foundation “and caused it to suffer millions of dollars in damages.”
