22 The nature and purpose of parole and the way in which a court should enter upon a determination of whether to make an order for eligibility for parole has been the subject of comment in numerous decisions. In Wongawol v R, unreported; CCA SCt of WA; Library No 980233; 4 May 1998, the Court of Criminal Appeal held that the same principles apply under Part 13 of the Sentencing Act and Part 3 of the Sentence Administration Act as previously applied under s 37A of the Offenders Community Correction Act 1963. The principles in question, enunciated originally in Thompson v R [1992] 8 WAR 387, and reiterated in Wongawol, are well-known and I will not refer to them in their entirety. In summary, and with an emphasis upon those principles relevant to the circumstances of the present case, it is apparent that once a court sentences a person to a term of imprisonment, the question of eligibility for parole must be considered. This calls for the exercise of judicial discretion which cannot be triggered unless there is something in the materials before the sentencing court which points positively towards the appropriateness of parole. Nonetheless, the philosophy of the Act suggests a bias towards eligibility. Parole serves to mitigate punishment as well as provide an opportunity for rehabilitation. In determining whether an order for eligibility for parole should be made, the sentencing court may have regard to all or any of the following factors, that is to say, the nature of the offence, the circumstances of the commission of the offence, the antecedents of the offender and circumstances which are relevant to the offender or which might, in the opinion of the court, be relevant to the offender at the time at which the offender would become eligible to be released from prison on parole if an order for eligibility were made and any other matter that the Judge thinks relevant.
