Glen, you can call for FOI notes till you are blue in the face. “he said she said” is irrelevant now so give up on the personalities thing. You have been declared persona non grata, the drawbridge has been pulled up and they are not listening except for a slip by you that allows them to declare that you are not “a fit and proper person” to be involved in Aviation at all.
This problem is not going to be solved within CASA. You need to take your complaints somewhere else.
