30 It was submitted on behalf of the appellant that the total sentence of four years imposed was manifestly excessive and offended the principle of totality. In my opinion, having regard to the appellant's appalling traffic and other criminal record, he was fairly to be regarded as an habitual and defiant offender who deserved to be severely punished, both with a view to his personal deterrence and for the protection of the public. It was relevant that, on the last occasion on which he was driving without a licence while disqualified, he was also convicted of dangerous driving causing bodily harm. In the circumstances, given that the maximum sentence in each case was one of imprisonment for 18 months, the four sentences each of 12 months imposed, looked at individually, could not be regarded as manifestly excessive. The totality principle requires that the overall sentence be proportionate to the degree of criminality involved and, particularly in the case of a youthful offender, that the overall sentence should not be crushing. That is a well accepted principle. In my view, not only was each individual sentence appropriate, the overall sentence was proportionate to the criminality involved. The appellant had demonstrated that, not only does he habitually act in defiance of the law, he is a danger to the public and appears to have adopted criminal behaviour as the basic pattern of his lifestyle.
