The parity principle does not confine comparison exclusively to total effective sentences when co-offenders have been sentenced for both common and unrelated offences. It is open to an appellant to contend that the individual sentence for a common offence reveals a parity infringement, though the analysis must account for the influence of totality considerations on individual sentences. Earlier WASCA statements in Jardim, Tresnjo and Wong suggesting a universal rule confining comparison to total effective sentences should not be read as establishing such a rule. Separately, guilty plea discounts under s 9AA of the Sentencing Act 1995 (WA) of 16-18% were upheld where pleas were not at the first reasonable opportunity and the prosecution case was strong.
