Families of 45 of the 47 passengers sued Comair for negligence. (Families of the other two victims settled with the airline before filing litigation.) Three sample cases were due to be heard on August 4, 2008, but the trial was indefinitely postponed after Comair reached a settlement with the majority of the families. Cases brought by Comair against the airport authority and the FAA, arguing each should share in the compensation payments, are now resolved. The case against the airport authority was dismissed on sovereign immunity grounds, and this ruling was upheld by the Kentucky Supreme Court on October 1, 2009. In Comair's case against the United States, a settlement was reached with the United States agreeing to pay 22% of the liability for the crash, while Comair agreed to pay the remaining 78%.
