 On 4 May 2009, the NIS voted almost unanimously to revoke the membership of Youroukov, Radonov and eight other “traitors”.The Central Electing Commission (CEC), a pool of all parliamentary represented parties, refused to register the Blue Coalition for the 2009 elections when the quorum of two thirds attendance was not met because the delegates from the Tripartite Coalition were absent.On 31 May 2009 the Supreme Administrative Court (SAC) overturned that decision, amidst allegations from the SAC chairman himself that he was pressured by outside parties.
