Para337, the Minister and the public service are consrained to act within the law and also to operate with fairness, Equity, Natural Justice and all that other good stuff. That means they have to follow procedure and assume everyone is acting in good faith.
In mu opinion Minister Joyce's letter is as good as it gets.
1. He has acknowledged the existence of Glens matter.
2. He explained that he has to follow procedure.
3. He has stated that he expects CASA to apply the terms of his SoE.
What more could you ask for?
If Joyce were to say "Too right Glenny! Those CASA B%^$$%^ have stitched you up!". Then its now Joyces problem, not CASA's, to negotiate a settlement and come up with a few million to make you whole.
