NPc Compact and interest groups?

[James]

From what I understand, the local PC has to unanimously approve expansion to a school.

When I see most of the threads talking about expansion, its from the point of view of the local PC looking to exapand and inviting groups to give presentations.

But what happens when you have a group of girls that want to create a sorority and have already decided they don't want to join the existing ones? Why does the local PC often stand in that groups way?

Lets say on a campus total is 70 and an interest group forms around some dynamic girl(s) and has like 60 members. This is a population that wasn't going to join an existing sorority. They have been on campus and looked around.

Why is the Local PC going to prevent them from affiliating? ?Is it just to be mean? Or is it a failure to understand economics?

I have seen this happen several times.
