I want to know the answer to the following question:
In what year was a group of independent schools found guilty of price-sharing?
All the background I'm provided with is that "However, Jean Scott, the head of the Independent Schools Council, said that independent schools had always been exempt from anti-cartel rules applied to business, were following a long-established procedure in sharing the information with each other, and that they were unaware of the change to the law (on which they had not been consulted).". Is that enough to answer the question?
Answer: no
