19 There is one other matter I need to mention. As I pointed out to Mr Goldberg in the course of the hearing, this was not the occasion to relitigate the factual contest as it emerged before her Honour. Nonetheless I permitted Mr Goldberg, in the context of his argument concerning the asserted unreasonableness of her Honour's conclusion, to address individual aspects of the evidence before her Honour. These included allegations as to the motivation behind the prosecution: that the prosecution was orchestrated by ASIO and that Mr Laughlin was engaged in harassment as Mr Goldberg claimed that Mr Laughlin had apprehended him on a previous occasion. As well there was considerable dispute about particular factual matters raised before her Honour such as the location of speed signs, the nature of the flow of traffic, the position of Mr Laughlin on the roadway, the failure of Mr Laughlin to show Mr Goldberg the speed gun reading, the lack of independent witnesses, the failure by Mr Laughlin to stop any other car at the time that Mr Goldberg's car was stopped, the lack of illuminating signs in the area, the lack of provision of information as to when schools opened and closed in the area. All these matters, ultimately, are irrelevant to the conclusion that I have reached. This is not the place for a canvassing of the pros and cons of the decision reached by her Honour who heard all the evidence, and reached a conclusion well open to her.
