On July 5, 2012, the U.S. Court of Appeals issued a 3-page ruling in Kurita v The State Primary Board of the Tennessee Democratic Party, upholding the action of the Tennessee Democratic Party in 2008 and also upholding the U.S. District Court decision of 2008. The incumbent Democratic State Senator, Rosalind Kurita, had won the primary, although by only 19 votes. But the party decertified her as its nominee, and instead nominated the runner-up. The party was hostile to her because she had voted for a Republican for Senate President. Also the Democratic Party charged that some of the voters in the Democratic primary were Republicans. Tennessee has open primaries.
The Sixth Circit decision has almost no original content, and on the merits, merely says that the U.S. District Court decision was correct. The implications of this decision are significant, because the U.S. District Court decision only covered Tennessee, but the 6th circuit decision will also control future similar disputes in Ohio, Michigan, and Kentucky, which are the other states in the Sixth Circuit. Thanks to Jim Riley for this news.
