If my child was prevented from going on a school trip that I'd paid for, if be taking the school to court. If that really was in an email to parents, the school is asking for trouble.
This. No one, not even a school, has any legal right to take money as payment, for example a school trip, and then withold what has been paid for and refuse a refund. Once the money has been handed over, a contract has been made between the pupil and the school. To refuse the pupil to go on that trip, or refuse to refund the money, is a breach of that contract. And they wouldn't stand a chance of winning if the pupil took his case to court.
So I'm very
about this claim.
