Sarcs, agreed. The Pelair special audit report, along with the relevant documented observations, NCN's, obtained evidence, written notes and list of persons spoken with, along with the names list of the Inspectors who undertook the audit will be on file. The audit report will also contain references to which part of the regulations they were non compliant with. If the audit report can't be produced then CASA has breached it's own procedures and due governance. Then again it's executives are promulgators of the 'do as I say not as I do' philosophy.
I see no reason why the Senators cannot be given this full audit documentation at a moments notice, it is as simple as pressing the print or send button. Any delay or stalling tactics should be viewed as suspicious to say the least. That is my concern, the stalling game. A royal commission would remove that little ace in CASA's deck of cards. The commissioner could simply call up all who he/she wishes to the witness stand your honour!
The other option is obtaining material under FOI however that is a wasted drawn out exercise as government departments have that issue nutted out perfectly, and getting anything tangible takes years, blacked out page at a time.
So yes, lot rests on the shoulders of the good Senators.
