R v Mason and Saunders

In the case of R v Mason and Saunders, the applicants, Mason and Saunders, were convicted of various offences including assault occasioning bodily harm in company, rape, and indecent assault. The applicants sought to challenge the application of Part 9A of the Penalties and Sentences Act 1992, which was enacted after the commission of their offences but before the imposition of their sentences. The key issue for the court was whether Part 9A could be applied to the applicants' situation, given that the offences were committed prior to the commencement of Part 9A, but the sentences were imposed afterwards.

The applicants argued that applying Part 9A to their case would contravene the principle of legality, as it would retroactively classify some of their convictions as serious violent offences. They contended that the sentencing judge's declarations under Part 9A were not applicable to offences committed before the commencement of the legislation. The court was required to determine whether the sentencing judge had the authority to make such declarations under Part 9A and whether doing so was compatible with the principle of legality.

The court considered the legislative intent behind Part 9A and the principle of legality, which requires that criminal offences and penalties be clearly defined by law. The court found that Part 9A did not apply to the applicants' situation as the offences were committed before the commencement of the legislation. The court held that applying Part 9A to the applicants' case would effectively alter the nature of their convictions in a manner that was not contemplated by the law at the time the offences were committed. Consequently, the court ruled that the sentencing judge's declarations under Part 9A were invalid in this context, and the applicants' sentences would not be affected by the provisions of Part 9A.

The final orders of the court were that the declarations made by the sentencing judge under Part 9A were quashed, and the applicants' sentences were to remain unaffected by the provisions of Part 9A. This decision underscored the importance of the principle of legality in criminal sentencing and highlighted the limitations of applying retrospective legislation to alter the nature of convictions for offences committed prior to the enactment of such legislation.
