The parity principle in sentencing is confined to co-offenders convicted of the same offence or to the range of sentences for the same kind of offence; it does not extend to sentences imposed upon other participants in related criminal conduct who were convicted in another State of different offences under different legislation. The fact that an accused has undergone two trials (following a successful appeal against conviction) is not a mitigatory factor warranting a lesser sentence on the second occasion; the only constraint is that the sentence on retrial should not exceed the sentence at the first trial.
