52 In those circumstances, it appears to me that the learned Magistrate, with respect, adopted an impermissible approach to the exercise of the sentencing discretion. While, with respect, he correctly commenced the sentencing exercise by beginning to consider the seriousness of the offence and by asking himself what the appropriate sentence would be for the single offence of burglary, as the remarks of McHugh, Hayne and Callinan JJ in Pearce v The Queen (supra) cited above suggest should be done before questions of cumulation or concurrence, as well as questions of totality, are considered, the learned Magistrate soon wavered from that approach. The transcript of the learned Magistrate's sentencing remarks shows that, while he considered the starting-point for a term of imprisonment "would be 18 months and upwards", he did not then form a concluded a view as to what sentence for the single offence was appropriate before considering the other relevant sentencing principles. He did not then formulate the view that 2 years' imprisonment was appropriate and proceed to consider a discount for a plea of guilty. Rather, he immediately had regard to what sentences had been imposed to this point and expressed the view that "it's clear that they have been extremely lenient". The learned Magistrate then regarded the "totality of his offending" and noted the "growing concern in the community about the volume and scale of burglary offences". In that context, he formed the view that a "total outcome of 4 years is about right". He considered that not to be a "crushing sentence". The difficulty with this approach, is that the learned Magistrate was not, on this occasion, called upon to sentence for anything but the single offence. His approach was to have regard, in my view, retrospectively, for what in his view the "total criminality" of the appellant's actions during the period March to May 2001 should have reflected by way of a term of imprisonment and then, having regard to the sentence actually imposed for which the appellant was still serving a sentence, calculated that a "2 year sentence should be imposed for this single offence".
