19 The offences for which the appellant was serving a total effective sentence of 7 years' imprisonment were committed in the period May 2002 to April 2003. The sentences under appeal were for offences committed in April 2003. The sentencing Judge was clearly correct in applying the totality principle. She did so by significantly reducing the sentences she would otherwise have imposed but, unlike Williams and O'Brien DCJs before her, concluded that the sentence should not be served concurrently with the total sentence of 7 years imposed by Hammond CJDC. I am not persuaded that the sentencing Judge erred in the exercise of her discretion in that regard. The aggravated burglary offence for which he was sentenced by Wager DCJ was appropriately characterised by her as serious. The circumstances of a number of the other aggravated burglary offences for which the appellant was already serving a term of imprisonment also fell within that category. The number and seriousness of the offences are relevant to the total criminality of the course of criminal conduct viewed as a whole. It cannot be said that the two further offences, added to the other 40 for which he had already been sentenced, did not add to the total criminality.
