Well actually MEL_Traveller, you were entirely accurate because if I am not mistaken, the ATSB and other Australian transport safety bodies tend to use the exact words you used - 'no blame.'
However again you are correct - 'just' might be a better description, because it would be unfair on society, employers and fellow employees if serious negligence or criminality went unpunished. As you suggest, the vast majority of 'errors' are not going to be deliberate. It reminds me of how judges and magistrates apply 'general deterrence' as one of their many sentencing techniques.
Take a bow, MEL_Traveller.
