I had an EEG for a Class1 in the late 70's. Mandatory then.
However, I am aware of a case in which someone I know had a very similar situation to the one you find yourself in. Everyone thought it was unfair and he sought the guidance of a neurologist one of friends knew. His view was that he would seek to discuss it with his counterpart and it was sorted fairly quickly.
Don't know if you could do that but in any event you must challenge it. Going higher if need be.
After all, if a consultant cannot stand by his view, what are any of his views worth?
