This is a bit ridiculous though. So, those found with a colour deficiency who hold an existing CPL(H) can continue to operate (albeit in a restricted capacity), but someone who has exactly the same medical results cannot obtain a CPL(H) in the first place?
That's quite distinctly discriminatory. Unless, of course, the answer to my question is "Yes", and that a CPL(H) can still be obtained with a restricted medical.
