There can always be issues as to whether a party to a contract freely and knowingly agreed to its terms. These are very fact-specific, and frankly these theories will not often overcome clear contract language, even if that language is tucked away in a sea of verbiage.
Bottom line. It stinks, but there is probably not a whole lot the students can do about it.
Possibly not in the legal venue (depending on contractual terms) but everything can be negotiated -- if you make a big enough stink.
Imagine a landlord demanding that a black renter agree not to use the white laundry room before being allowed to rent. Think that paper would stand up in court?
