Now here’s an interesting thing in light of my recent experience… on Friday 9 June 2016 the ACT Legislative Assembly passed the Justice and Community Safety Legislation Amendment Bill 2016, and one of the amendments was to specifically target that act. The explanatory statement 5 May 2016 (PDF) reads,
The Bill introduces a specific offence in the Crimes Act 1900 to clarify that the practice of throwing or directing objects at vehicles (including riders of bicycles) is criminal conduct.
There is no specific offence presently prohibiting this conduct in ACT legislation, either in the Crimes Act or road transport legislation. Prosecution of this behaviour using existing offences (such as assault) is possible but problematic.
I doubt that it would have made much difference in my particular case as the ‘assailant’ was motivated to admit to the incident. However, like the 1 metre rule sets a standard that can be reasonably adjudged, so too that act of throwing or directing and object at any vehicle can’t be argued down under the ‘no harm, no foul’ schoolyard rule.
