I don't know about that Andy but I know RT talked about strict liability for the Commonwealth Criminal Code offence discussed on the Roar previously. Beale may still have a mistake of fact defence but that appears unnecessary as the prosecution does not appear to have a witness, and their is doubt about the veracity of the actual evidence. How an impartial body could find against Beale for anything under these circumstances would be an interesting turn because it would appear they are no longer impartial.
Under the Qld Criminal Code it is a crime where it is incumbent upon the prosecution to prove that the defendant 'knowingly' was in possession of such material. To prove 'knowingly' that must be to a standard of beyond reasonable doubt.
What if there is a home computer, and one member of the family does involve themselves in that garbage, but the other members of the family are totally unaware - do you charge every member of the family because they all use the same computer - I would hope not.
Perhaps a personal protest? It is not lost on me that this hearing may deny KB the opportunity to tour England, home of the Magna Carta...
