How are the officers elected? Do you have to be on NIC a certain number of terms? There's no reason that exec board should only be composed of 2 fraternities. Some of the other fraternities need to pick someone to stay on NIC a long time and get elected.

I'm also not sure about this business of the exec board picking the jud board - at any rate, they shouldn't be allowed to just pick their brothers and no one else (which I assume is what is happening).

You really need to go to your Greek advisor (or if he won't help, to whoever is over his head) IMMEDIATELY. There's no reason for things like withholding the bylaws from you - every fraternity should have a copy of them and they should be easily accessible at the Greek life office.
