8 In DPP v Karazisis; DPP v Bogtstra; DPP v Kontoklotsis[5] the Court observed that, conceptually, a Crown appeal has traditionally given rise to three separate questions which can be described as 'stages'. First, the Court considered the nature of the sentencing error in order to determine whether it satisfied the common law requirements, summarised in Clarke[6] and Bright,[7] which were intended to ensure that such appeals should be 'rare and exceptional', and did not unduly circumscribe the sentencing discretion.[8] Secondly, even if the error met those requirements, the Court would consider whether, for reasons of principle or because of discretionary considerations, it should decline to intervene because it did not consider that a different sentence should be imposed. For example, the Court would exercise what it regarded as an overriding, or residual, discretion not to intervene where it did not consider that there was a sufficient difference between the sentence imposed at first instance, and any sentence it regarded as appropriate.[9] Thirdly, if the Court did intervene, because it was a Crown appeal the Court would impose a lesser sentence than it would otherwise have imposed, which was generally toward the lower end of the appropriate range.[10]
