(1) Subject to this section and sections 637, 638 and 639, the Youth Parole Board, by order, may cancel the parole of a child or young person released on or granted parole under section 627 at any time before the end of the parole period.
(2) If the child or young person is sentenced to a term of imprisonment or to a period of detention in a youth justice custodial centre for more than 3 months in respect of an offence committed during the parole period, whether in Victoria or elsewhere, the Youth Parole Board may cancel that child's or young person's parole, whether or not the parole period has already ended.
(3) If a child's or young person's parole is cancelled under subsection (1)—
(a) the original warrant or other authority for the child's or young person's detention revives; and
(b) unless the Youth Parole Board otherwise orders, having regard to the extent to and the manner in which the child or young person complied with the parole order, no part of the time between being released on parole and recommencing to serve the unexpired portion of the period of detention is to be regarded as time served in respect of the period of detention.
(4) If section 667 applies, the original warrant or other authority for the child's or young person's detention is taken to be a warrant to imprison the child or young person in a youth justice custodial centre.
