Newspapers in Tennessee have run stories recently about the Green Party and the Constitution Party nominees for public office. For example, see this story. Both parties were put on the ballot by a U.S. District Court, in February 2012. They are the first two parties in Tennessee to be recognized since the period 1968-1972, when the American Party was on the ballot.
The Green Party has nominated six candidates for Congress, and five for the State House. The Constitution Party has only nominated one candidate, who is running for the U.S. Senate. The twelve candidates from these two parties could conceivably be removed from the November ballot, if the state succeeds in persuading the 6th circuit to reverse the decision of the U.S. District Court.
