24 First, the leave to appeal against conviction issue. For present purposes, and without further analysis, I am prepared to assume that the question identified above about the Court's duty involves a question of law alone. On that basis the Court's discretion to consider the question of leave is enlivened. The granting of leave to appeal against conviction, in this case, will necessarily also permit Mr Kwong to change his plea from guilty to not guilty. Accordingly, the principles identified above also apply. The decision of Biscoe J in Great Lakes Council v Mood (2007) 157 LGERA 35 provides a convenient summary of the law with respect to entry of pleas. After reviewing the authorities (at [14] to [24]) Biscoe J summarised the law as follows (at [25]):
The following principles, in my view, are supported by these authorities:
(a) the Court must accept a plea of guilty which is unequivocal and not made in circumstances suggesting that it is not a true admission of guilt (those circumstances include ignorance, fear, duress, mistake or the desire to gain a technical advantage). If a plea of guilty is equivocal the Court must enter a plea of not guilty. However, ordinarily, a plea of guilty is not finally accepted by a court until sentence has been passed. See Maxwell at 511, Foster, R v Jerome, R v Tatnel, R v GV.
(b) a person is free to plead guilty even if he is not, and may do so for all manner of reasons (for example, to avoid worry, inconvenience or expense; to avoid publicity; to protect family or friends; or in the hope of obtaining a more lenient sentence than if convicted after a plea of not guilty). It is not a miscarriage of justice for the court to act on an unequivocal, freely made plea of guilty even if the person is not guilty: Meissner at 141, 157.
(c) if the trial judge forms the view that the evidence does not support the charge or that for any other reason the charge is not supportable, he should advise the defendant to withdraw the plea and plead not guilty; but he cannot compel the defendant to do so: Maxwell at 510.
(d) the court has a discretion to permit a change of plea at anytime prior to sentence if it would be a miscarriage of justice not to do so: R v Marchando (2000) 110 A Crim R 337 at [4].
