15 The sentencing judge was in no position to form a view on the question whether the appellant would serve his full time or be granted remission. It is true that s 21 of the Corrective Services Regulation 1989 is headed "General Entitlement to Remission" and that the heading forms part of the section[3]. Moynihan J adopted this description in R v Griinke[4] and in the same case, Thomas J referred to remission amounting to one-third of the prison sentence as "generally obtainable". In R v Coss[5], Thomas J referred to such remission as being granted "in the ordinary course". Nonetheless, at least since the decision of this court in McCasker v Queensland Corrective Services Commission[6], the granting of remission could not have been assumed by the sentencing judge. Nor could it have been assumed that remission would not be granted in respect of the period of the sentence after 20 August 1998. True, the appellant's behaviour up to that date, insofar as it was known to the court, did not fall within the definition of "good conduct and industry" in s 21(2) of the Regulation, in that he had committed a number of offences. However s 28 specified the effect that those offences should have on the grant of remission; without more, the offences would not be sufficient to disqualify the appellant from remission in respect of the period after 20 August 1998. On the material available on the sentencing day, a conclusion regarding remission would have been speculative.
