As to issue (3):
When sentencing an offender for an offence constituting a breach of a condition of parole, the determination of the commencement date involves the exercise of a discretion having regard to questions of cumulation and concurrency. Given the length of the extant parole period, the nature of the further offence, and the legislative requirement the sentence commence no later than the date of sentencing, the new sentence was (and would be on resentence) subsumed within the balance of parole. It was therefore to be served entirely concurrently.
It was a matter for the State Parole Authority to determine whether, and what part of, the parole period of the earlier sentence during which the applicant was not serving a non-parole period for another offence, should be properly served in the community. The State Parole Authority is not concerned with punishment, but with the safety of the community. Dating the sentence from a point after the revocation of parole would have the effect of adding to the punishment of the offender for the present offence. That is because it would have the effect of taking the decision as to whether and when the offender might be re-released to parole out of the State Parole Authority's hands for a period equal to the period between the date of revocation and the date on which the new sentence commenced. The period of the earlier sentence to be served in custody should be left to the Parole Authority and the new sentence backdated to the date of the applicant's arrest, 5 July 2023: at [2]-[4] (Basten AJA); [45]-[55] (Dhanji J).
