I agree that Mr Skidmore should not be blamed for the outcomes of the survey. Subject to a couple of exceptions, he inherited a mess that has been created over a couple of decades and was never going to be cleaned up during Mr Skidmore's fleeting tenure. (The exceptions were his response to CVD and the ASRR Report. Both were unnecessarily self-inflicted wounds for which he would have been charged if still a member of the ADF.)
The reason that nobody in CASA is held responsible for the regulatory reform Frankenstein is that they cannot be held responsible. The reason they cannot be held responsible is that they are not responsible in fact. The people who are responsible in fact don't in fact work in CASA. But they are happy to let CASA take the blame. That's CASA's job.
Are the police responsible for reforming the criminal code? Nope.
Is ASIC responsible for reforming the corporations law? Nope.
Is the ATO responsible for reforming the tax law? Nope.
Name me any regulator that's successfully driven the reform of the regulatory system that the regulator itself administers.
