Glen I watch your case with fascination and wish you well in your endeavor for justice but I wonder if it is counter productive to copy CASA into correspondence such as this. It does appear that you need a "Political Champion" to further your case against what appears to be a classic example of the modern Australian public servant who is able to hide behind the motto "not in the public interest" to address issues/stuff-ups they have caused whilst also mouthing that they are model litigants.
As I say keep searching for your "Political champion" but reduce the amount of stuff you copy to CASA.
All the best with your endeavor for justice.
