I think K has a point here, take a look at the Seaview report from about pg 44 onwards:

BASI (as they were known then) kicked the regulator so many times (13 directly) that their noses would have left a trail of blood from the accident site to Lord Howe and back to Canberra....all without stepping outside the boundaries of their remit!
No wonder the metamorphosed CASA promptly circled the wagons, battened down the hatches and have been in seige mode ever since!
