The word 'cancelled' in s 71(1) of the Sentence Administration Act 1995 (WA) means 'cancelled in fact' and not 'validly cancelled'. The CEO's authority to detain a prisoner following cancellation of parole is not dependent on the validity of the cancellation order but merely upon the fact that it was made. An invalid parole cancellation order has legal effect for the purpose of calculating a prisoner's release date and authorising detention until it is set aside by a court. The statutory scheme provides separate mechanisms (s 115A review and s 49 resolution of doubts) for challenging the validity of cancellation orders, and these are the appropriate avenues rather than treating the order as having no effect.
