#Competency of appeal against conviction following a plea of guilty
The appeal against conviction was incompetent because the plea was voluntary and unequivocal, engaging the bar in section 348.
The court examined the plea in mitigation, including the reference to a 'painful experience' in custody, and concluded it was a plea in mitigation seeking leniency by a man in full command of himself, not an alert to coercion. The plea was therefore voluntary and unequivocal, so section 348 applied in full force and barred the appeal against conviction.
Admission of additional evidence on appeal
Application to call additional evidence refused; the evidence would be irrelevant since voluntariness was decided against the appellant.
The point the additional evidence was meant to establish was the involuntariness of the plea, which the court had rejected on the record. With voluntariness closed, custody ill-treatment evidence could not assist. No review lay either, as the magistrate followed correct plea procedure and there was nothing reviewable.
Appeal against sentence
Section 348 does not bar an appeal against sentence, but the appellant made no submissions and the sentence was upheld.
Though the appellant was free to pursue the sentence appeal, counsel made no submissions on sentence and the State had nothing to add. The court therefore upheld the fifteen-month imprisonment term and dismissed the appeal against sentence.
Legal principles established
#- Section 348 of the Criminal Procedure Code bars an appeal against conviction where the plea of guilty was voluntary and unequivocal; only an appeal against sentence lies.
- Only a voluntarily entered plea of guilty is caught by section 348; a plea induced by threats is invalid and no bar.
- Where voluntariness has been decided against an appellant, evidence of ill-treatment in custody is irrelevant and cannot be admitted on appeal or review.
