Question about missing a recruitment event

[AOII*Azra-elle]

One of my chapter sister's has a wedding on the day of our pref ceremony. The girl getting married is an alumna that alot of the older active members don't like. The girl going gave her excuse for recruitment at the beginning of summer. Now, with recruitment being a little over a week away they are telling her she can't go to the wedding or she'll be fined, and that it has to be approved through the AAC. How do other chapters deal with things like this? Do you guys have to get approval for this? We never have before. Things like illness, bereavement and weddings have always been excused before, but now they want to change it without the chapter voting on it.
