Why don't you organize yourselves and do a new vote right now?
Because he has stated that even if he was removed as CEO by a shareholder vote, he would continue with his plan to shut down GLBSE.
Anyway, there are a few reasons why the vote to remove Nefario as CEO failed. First, he has a 24% stake in the company. Second, he had a couple of minor supporters. Third, most of those that opposed him in principle were already resigned to the course of events and didn't care to actually take a stand, as even if he was removed, he stated he would shut it down anyway.
The fact that he stated to shut down GLBSE anyway is irrelevant. Other partners should still take an official stand by passing a motion to remove him as CEO. He has a large stake in the company, but it is not even close to 50% After his last fuck-up it should be possible to get a majority to vote him out.
On the other hand, maybe you don't want the company anymore. Nefario now being the scapegoat is a very easy way out for all other partners. So nobody has to take responsibility for the mess that has been created. It is all Nefario's fault.
