"The sentencing judge possesses a discretion of great
width. It would be improper to seek to define or prescribe
the area in which that discretion is to operate. It is for
the judge to interpret the quality and implications of the
plea. If it is one calculated to serve the public interest
it would be proper to consider whether to allow the plea to
act in mitigation, but not necessary to do so. For example,
the plea may be evidence of remorse, that is, regret as to
participation in the crime. If the Court of Criminal Appeal
in Queensland in R v Cox, (1972) QWN 54 held that a plea of
guilty could operate in mitigation only in so far as it
evidenced genuine remorse, that, in our opinion, would be a
too restrictive view. There are other factors that operate
in the public interest. The plea may operate, and may have
been so intended, to save a prosecutrix the ordeal of giving
evidence in a sexual case. The plea may serve, and may have
been so intended, to save the State a lengthy and expensive
trial. Yet in neither of such cases might the accused feel
genuine remorse. There may be cases in which the only
sorrow felt by him is in the fact that he has been detected.
But, having been detected, he has had to do the best he can
for himself. Weighing the strength of a possible defence
against the likely penalty upon conviction he may elect
deliberately to adopt a course which involves a measure of
public utility in the belief that his own ultimate interest
is best served by doing so. The judge may (not shall) take
such circumstance into account in the accused's favour. If
such action be tainted overmuch by self-interest it probably
will not avail the accused. Professor Sir Rupert Cross in
his book The English Sentencing System (1971), p153 suggests
that it is in the interest of the present judicial system
that provided they are in fact guilty, accused persons
should plead guilty. No doubt great cost to the community
in time, convenience and money is thereby saved. However
expedient this may be from the point of view of the
executive, it is not a matter which requires the sentencing
judge to reduce the sentence below that which he otherwise
believes to be proper in the circumstances.
On the other hand, there may be pleas of guilty which are
not designed to serve the public interest or may do so only
marginally or incidentally. That is to say, the accused's
self-interest is completely predominant in the decision
reached by him. One such case will be when the accused is
quite unrepentant and confesses his guilt simply because the
case against him is overwhelming and, in a practical sense,
unanswerable."
