Frank beat me to it...so what he said blackie! Or you could end up revisiting the CDPP for an entirely different matter...
I'm also with Frank (and probably most of the aviation fraternity that has taken the time to read the Hansard) and believe there is more than enough evidence of malfeasance, obfuscation and maladministration contained within the public hearing that any 'in camera' evidence is just icing on a rotten cake.
Therefore what Kharon said:
The next thing (Shirley) for the Senate must be to open up a general inquiry into the real impact of CASA actions across the industry. A full and open assessment will lead to a Royal Commission, because if the lid is coming off this crock, whoever is the minister will want control. I wonder if a new government will institute a reformation? They sure need to.
Senators, or who ever, as the 'Ginger Ninja' said "bring it on!"
