In the present case, I am of the view that the circumstances of hardship do not warrant the exercise of mercy such as to reduce the period of the head sentence that would otherwise be appropriate. I consider that the aggravating circumstances of the offending and the applicable sentencing principles are such as to leave no room for the proper exercise of mercy in that regard. In particular, I think that the importance of the operation of the principle of general deterrence and the need for the Court to express denunciation of the offending conduct requires the imposition of a head sentence in respect of each count, and a total effective sentence, that properly reflects the gravity of the offending, obviously in the context of the mitigating circumstances. It is impossible not to sympathise with the applicant's family and recognise the hardship that they will bear because of his imprisonment, but in all the circumstances, as I have said, I consider that this does not justify the exercise of discretion to extend mercy in relation to the head sentence. It is important to bear in mind in this context the caution sounded by Callaway JA in Carmody,[11] namely that the sentencing judge will be failing in his or her duty of proper sentencing considerations where overwhelmed by an emotional response to the hardship that a sentence would impose upon the family of the offender. Similarly the exercise of mercy should not undermine the general principle that, save for exceptional circumstances, hardship to family members by reason of the offender's imprisonment is not a relevant consideration for sentencing purposes.
