8 The error which is ascribed to the primary judge is that his Honour did not adjust the sentence imposed on the applicant in such a way as to avoid the creation of the gap, said to be too large, between the punishment imposed on the applicant and that imposed on Banks. Specifically, it is said that if there had been a sentence of 9 years producing a non-parole period of 4½ years, the relationship between the applicant's sentence and that imposed on Banks might have been much more defensible. There was discussion before us as to whether, if the sentence were reduced in this way, a declaration would be made under s. 161B(3). The Crown argues that the judge was not entitled to take the course contended for by the applicant, which it is said is inconsistent with this Court's decision in Booth (CA No 338 of 1998, 30 March 1999). Booth was sentenced to 12 years imprisonment for various offences and because of the provisions of s 156A(1)(b)(ii) of the Penalties and Sentences Act 1992, dealing with offences committed while on parole, the 12 year sentences had to be made cumulative upon a substantial balance remaining to be served under earlier sentences. Booth relied in his application on the totality principle, because the result of the sentences imposed on him was that he had a full-time release date more than 17 years ahead. Further, because of the provisions which are in question here requiring service of 80% of the term before eligibility for parole, the parole date was considerably deferred. McPherson JA referred to a method of setting parole, where a cumulative sentence is imposed, which was discussed in Coss (1995) 78 A Crim R 551. I interpolate, although it is not relevant to the present case, that a method of fixing a parole date, said to be that advocated in Coss, was not treated favourably in Walton (CA No 338 of 1997, 18 November 1997), a case on which comment was made in Hartigan (CA No 109 of 1998, 17 September 1998). To return to the principal point of Booth, McPherson JA referred to the statutory requirement in s 156A(2) that the sentences in question be served cumulatively and said:
