The Libertarian Party filed a federal lawsuit over the Kentucky U.S. Senate debate on September 28, 2014, called Libertarian National Committee v Holliday, eastern district, 3:14cv-63. Judge Gregory Van Tatenhove denied injunctive relief, and the Libertarian U.S. Senate nominee, David Patterson, was barred from all debates.

The case is still alive. Patterson and his party charge that the debate sponsors changed the rules on which candidates should be invited. When it appeared Patterson might qualify, the debate sponsors said no one could be invited who had not raised at least $100,000 and was at 10% in the polls. Patterson and the party requested permission to file an amended complaint back on November 6, 2014, and the judge still has not ruled on whether the amended complaint can be filed. The amended complaint contains new information that had not come out when the original complaint had been filed. It also asks for a jury trial.
