There is a very simple fix to a lot of the CASA problems.
If I remember rightly Dick Smith tried to have it implemented.
Basically make each CASA employee personally liable for their actions and decisions.
If my accountant or Doctor stuffs up I have the legal right to sue them for either breech of contract or mal practice. It then gets taken up by their professional insurer and eventually right is corrected.
In the case of CASA, either the organisation or the individual would need professional indemnity insurance.
This simple change to make the individual responsible for their actions would see CASA staff at least think twice before going off on some tangent other than the law.
But I forgot CASA lives in a very special world of do what I say not what I do.
