I'm having a go at answering the question, "Why do City say the Rules are void?"Thanks Vic but it says….
“that the APT Rules are unlawful on account of being in breach of sections 2 and 18 of the Competition Act 1998 because they exclude from their scope shareholder loans and for no other reason;”
That says to me that if the shareholder loans area is corrected then it becomes lawful as they state that is the only reason?
Because that's what the law says. If the Rules are unlawful (for whatever reason) they are prohibited rules and any agreement, or decision of an association, including the prohibited Rules is thus void. [Competition Act 1988, s.2(4)]
