Tilley v The Queen

This matter concerned an application for special leave to appeal to the High Court of Australia by Mr S.W. Tilmouth, QC, appearing with Mr A.J. Crocker, for the applicant, Mr Tilley. The respondent was the Queen, represented by the Solicitor-General for South Australia, Mr J.J. Doyle, OC, and Mr P.J.L. Rofe. The dispute revolved around sentencing principles in South Australia, specifically concerning the impact of remission systems on the proportionality of sentences.

The legal issue before the Court was whether a legislative amendment in South Australia, enacted in response to previous High Court decisions, correctly reflected the principles of sentencing. The applicant argued that the amendment, which introduced subsections (2) and (3) to section 12 of the Criminal Law (Sentencing) Act, effectively mandated an increase in head sentences to negate the benefit of remission, thereby contravening established sentencing principles.

The applicant's argument, as presented, relied on the High Court's prior judgments in *Reg v Hoare and Easton* and *Reg v Dube and Knowles*. In *Hoare and Easton*, the High Court had reaffirmed that a remission system, on its own, should not be a reason to increase a sentence, and that the fundamental principle of sentencing is proportionality to the gravity of the offence. The Court had disapproved of remarks in *Dube and Knowles* which suggested that regard for remission systems could justify increasing head sentences by up to 50 per cent. The applicant contended that the new South Australian legislation, by requiring sentencing judges to have regard to the remission system in a manner that effectively negated its benefits, undermined the principle of proportionate punishment and frustrated the operation of the remission system itself.
