18 In Stewart v Waghorn, Miller J dealt with an appeal against a sentence of 15 months' imprisonment imposed for a sixth offence of driving under suspension. The appellant in that case had previously, in respect of his fifth conviction for driving while under suspension, been sentenced to 12 months' imprisonment, suspended for 2 years. The appellant had, after that conviction, been diagnosed as suffering from Attention Deficit Hyperactivity Disorder. Miller J held that an appropriate sentence would have been one of 6 months' imprisonment and, because of the appellant's medical condition, diagnosed after the previous suspended sentences had been imposed, his Honour directed that the sentence of 6 months which he substituted for the 15 months ordered by the learned Magistrate, would be suspended for 12 months.
