Well, in the case at NMSU, the panhellenic association (5 existing NPC chapters) voted to expand. They then sent out the information to NPC and then on to the 21 NPC groups not on campus. Many of the groups sent back information expressing interest in the process. The expansion committee then reviewed the packets of information from the NPC groups which responded and decided to which three of them to invite. The same committee saw the presentations and will make the desision on who to invite.

This question comes under the NPC "authorizing authority" provision. If no NPC groups are on campus, then the campus administration is the authorizing authority. If NPC groups are on campus then the panhellenic association is the authorizing authority and must vote to expand and issue the invitations for presentations.
