"A miscarriage of justice may occur in many different situations if a prisoner is not permitted to withdraw his plea of guilty. Such a miscarriage will be established not only where the applicant did not appreciate the nature of the plea which he had entered but also, for example, if there was no evidence upon which he could have been convicted, or if he had not intended to admit that he was guilty or if his plea had been induced by fraud or threats or other impropriety, when he would not otherwise have pleaded guilty. The authorities are collected and discussed in Chiron (at 235), in Sagiv (1986) 22 A Crim R 73 at 80-81; Bell (1987) 8 NSWLR 311 at 314-315; 28 A Crim R 417 at 420-421, in Liberti (1991) 55 A Crim R 120 at 121-122 and in Davies (unreported, Court of Criminal Appeal, NSW, 16 December 1993) at pp 2-5, 7-9, See also Jupp (unreported, Court of Criminal Appeal, 23 November 1993) at pp 2-3. As Badgery-Parker J said in Davies (at p 8), there must be shown to be some circumstance which indicates that the plea of guilty was not really attributable to a genuine consciousness of guilt. In so far as this Court's decision in Foley [1963] NSWR 1270 (upon which the applicant relies) may be taken as suggesting that there is some right to the grant of leave to withdraw a plea wherever the applicant bona fide wishes to be tried by a jury, I would not, with respect, follow it. The requirement that a miscarriage of justice be demonstrated before leave is granted to withdraw a plea is well settled in the authorities to which I have referred."
