Quick Take

When applying s 8(5) of the Sentencing Act 1995 (WA), the preferable approach is to determine the ultimate sentence having regard to all mitigating factors (including past and future cooperation), and then identify the sentence that would otherwise have been imposed without the promise of future cooperation; the difference between those two sentences is the 'reduction' for s 8(5) purposes.
