16 Thus, the principal question to be determined in the exercise of our discretion is whether in all of the circumstances the total period of nine years and four months to be served by the appellant breaches the principle of totality. In determining whether the sentence offends the principle of totality and is manifestly excessive, I have taken into account the matters urged on the appellant's behalf, and in particular the significance of the appellant's confession to most of the offences, the fact that the offences occurred over a limited period and were committed because the appellant was heavily addicted to heroin, the risk that the appellant would become institutionalised as a consequence of the sentence imposed, the fact that the appellant has remained drug free on remand, has family support and prospects of employment on release, and the fact that the appellant's parents, to whom he was close, suffer from declining health. Taking into account the intention of s 16(3B) and the length of the parole sentence, I am not persuaded that the term of imprisonment which the appellant is now required to serve can be said to be an unjust or inappropriate measure of the total criminality involved. That is to say, the sentence of nine years and four months' imprisonment cannot in all of the circumstances be described as manifestly excessive. I would therefore dismiss the appeal.
