"The policy must be that the conviction is a matter for the
criminal law and its procedures. Appeals are there
available. If new or fresh evidence comes to hand, the
criminal procedures can be availed of. There can in rare
cases be an application for a pardon, perhaps preceded by a
special judicial inquiry. While it stands, the conviction
must be conclusive, so far at least as concerns a Tribunal
reviewing a decision which takes the conviction and the
Minister's decision as its starting point. When I say
conclusive, I mean conclusive as to the guilt of the accused
in relation to the offence charged, and of the sentence
imposed. This is my understanding of the statutory
intention. Quite obviously, serious practical questions
arise if the position is otherwise. The Tribunal could
presumably arrive at its own decision as to whether the
person concerned did what he was charged with doing, and for
that matter, what sentence his offence merited. It would be
doing so on material gathered and considered at what could
be a long time after the trial, when some witnesses for the
prosecution were unavailable and memories were in any event
dimmed. Accepted trial procedures would be absent. The
Crown, as repository of the function of criminal prosecutions,
would not be a party. The Tribunal might in the end find
itself substituting its own view for that of the jury."
