JUDGMENT Edgley, J. - In this case there is no evidence to the effect that the constable, whose signal was disobeyed, was a police officer in uniform posted or stationed at the crossings or other places for the regulation of the traffic; and the order of the learned Magistrate does not contain the requisite finding on this point. The rules make it clear that police officers, who are posted at various places for the regulation of traffic., must be in uniform, presumably because traffic directions given by officers in plain clothes are likely to result in confusion. It is therefore necessary in cases under the traffic rules that there should be evidence to the effect that there has been a formal compliance with the provisions of the rules. Having regard to the observation made above, this Rule must be made absolute. The conviction of the Petitioner is set aside and he is acquitted. The fine, if paid, will be refunded.
