This video records the reaction by activists Alex Bainbridge and Kamala Emanuel after a significant court victory on 28 May 2013.
Emanuel had been charged with failure to comply with a move on notice that was issued during a rally against gas fracking in April 2012. She didn't claim to have complied with the move-on order but only that it had been issued invalidly - that is that there were no reasonable (or indeed legal) grounds for the move on notice to have been issued.
The magistrate Mr Huston found Emanuel "not guilty" and acquitted her of the charge.
His verdict found specifically that the Perth City Council rangers had no legal authority to seize the banner that sparked the issue and that the move-on notice was invalid.
