[17] The appellant has relied on a number of cases which he claims are comparable to demonstrate manifest inadequacy. In Irlam a sentence of 5 years imprisonment with parole eligibility after 12 months was increased on an Attorney-General's appeal to 7 years imprisonment with release after 2 years. Like the present case, it involved a serious breach of trust by a school teacher who sexually abused a female student, but the child was younger (10-12 years old) than the principal complainant in the present offences and Irlam's course of conduct included an offence of penile rape. Further, Irlam went to trial and so did not cooperate with the authorities, nor did he have the significant remorse and rehabilitative prospects of the respondent in this case. When these features are taken into account, although Irlam involved only 1 child instead of the multiple victims in the present case, it suggests the effective sentence imposed in the present case of 6 years and 3 months to serve 17 months before eligibility for release on parole was within range. Similarly, in CX, the offending conduct was more serious than here; it included penile penetration and sodomy and the sentence of seven and a half years imprisonment again was imposed after a trial. In MAM a sentence of six years imprisonment was imposed, again after a trial. The offences in May, as in Irlam, were perpetrated on a pre-pubescent girl. May, like the respondent, pleaded guilty. But the fact that this Court did not regard as manifestly excessive the sentence imposed there (6 years imprisonment with parole eligibility after 2½ years) does not persuade us that the effective sentence of 6 years and 3 months imprisonment with parole eligibility after serving 17 months was manifestly inadequate in the present case. These cases do not demonstrate that the effective sentence imposed on the respondent was outside the range established by decisions of this Court.
