Our Collegiate Panhellenic only allows one local sorority on GT's campus at any given time. We have filled that spot since 2001. It is also by their decree that the Associate Members (ADChi, AOE, and LTA) and Local (us) have a designated week in which we are allowed to rush, always one or two weeks after NPC recruitment.
Only the 6 NPCs represented on our campus have a vote at council meetings, so we're ultimately just subject to their will. Recently, the presidents of ADChi, AOE, and Coyote wrote a bill to give limited voting rights to Associates and Locals, but the motion failed when brought to a vote last week.
