Jackson v The Queen

This matter concerned an application for special leave to appeal to the High Court of Australia by Rex Frederick Jackson. The dispute arose from a decision of the Court of Criminal Appeal, which had found the sentence imposed on Jackson to be manifestly inadequate. The Crown's sole ground of appeal to the Court of Criminal Appeal was this inadequacy.

The legal issues before the High Court involved the principles governing sentencing, particularly in cases where co-accused have received different sentences. Specifically, the Court was asked to consider whether the Court of Criminal Appeal had erred in its reasoning by focusing on the disparity between Jackson's sentence and that of a co-accused, Harris. The applicant argued that the majority judgment in the Court of Criminal Appeal had espoused a principle of disparity that was not recognised in law and improperly interfered with the trial judge's sentencing discretion.

The applicant contended that the majority of the Court of Criminal Appeal had introduced a novel and radical principle into sentencing law. This principle, it was argued, suggested that a sentence should be adjusted upwards to avoid disparity with a co-accused's sentence, a proposition the applicant submitted was erroneous and unknown to the law. Furthermore, the applicant argued that this approach fundamentally altered the role of the Court of Criminal Appeal, shifting its function from reviewing the appropriateness of a sentence within a judge's discretion to confirming an existing sentence, and that this created a precedent with significant implications for the administration of justice. The applicant sought special leave on the basis that the case raised matters of general public importance concerning the roles of trial judges and appellate courts in sentencing.
