Lord Flashart,
I really am very surprised about the CAA taking this standpoint. Who is that you have talked to about it? Is it just an advisor who has said that they will not accept it? You should speak again to Dr Evans (Cheif medical officer) and get her to actually give the definitive answer. One thing that I have found with the CAA medical department is that the advisors, helpful as they are, can give different answers on different occasions. Keep putting on the pressure, there is no reason that they cannot accept your medical, so just keep writing calling etc and keep the pressure on, threaten legal action if need be (altho as a last resort!) Hope it all works out!
