The Victorian Court of Appeal has recently considered the object of "harm minimisation" in the context of the Victorian Liquor Control Reform Act 1998. The Court cited with approval the following passage from a Western Australian decision
"to ‘minimise’ harm or ill-health, not to prevent harm or ill-health absolutely. The word ‘minimise’ is consistent with the need to weigh and balance all the relevant considerations."
The case Kordister v Director of Liquor Licensing & Anor [2012] VSCA 325 can be found here.
