NPC bids

[Lynzi]

Just something I want cleared up.
In the fall, there was one girl that the chapter was divided on, but the division was not enough to keep her from getting a bid. She didn't get pinned/go through initiation because of problems with her parents.
All the girls in the fall class disliked her (including myself) because she made us very uncomfortable. She made a lot of the girls think twice about joining, just because she might be one of their sisters. Her actions tend to be immature and inappropriate. We had two alums who fought for her very strongly, and pushed the vote in her favour (even though they don't get a vote).
The problem is this: if she decides she wants to join in the next rush (winter), do we have to let her in even though with the new girls she would be voted against very heavily (the fall class outweighs the old chapter)? I know that NPC bids are supposed to be honoured for a year, but how does it work if the majority of the chapter is extremely uncomfortable with the idea of her being a sister? Can it be contested?
We don't run by formal rush rules (there's only two NPC sororities on campus and the other one doesn't want to run by NPC rules for rush), so I'm not sure if this can be used as a loop hole (as awful as that sounds). Sorry if this should be in the rush forum, but I think it might be a little scary for PNMs to read, and I think it applies here as well.
