One argument against that interpretation is to be found in sub-par. (i) of par. (e) of s. 399. Why, it is naturally asked, should the express provision be made in favour of allowing questions as to the commission of offences and convictions of offences where relevant if without any provision expressly permitting it the accused as a witness may be asked questions simply because they are relevant to proof of the ingredients of the crime, notwithstanding that they do affect his character? The reason is, one may reasonably suppose, that the draftsman saw the two things in different lights. When he expressly prohibited proof of the commission of an offence or of a conviction of an offence the draftsman saw that he was expressly prohibiting proof of a fact he definitely identified independently of its operation or of the ground of introducing it in evidence. On the other hand, in the case of "questions tending to show that he (the accused) is of bad character" the draftsman was dealing with a description of cross-examination going to credit which he thought of as, ex hypothesi, outside the field of relevancy altogether. In other words, in the case of strictly relevant facts he was regarding them as open to proof as part of the Crown case and as necessarily, or at least as naturally, the subject of evidence by the accused if he were called as a witness on his trial and he regarded them as not matter going to the bad character of the accused but as matter going to proof of his guilt. The words describe questions as to that kind of evidence excluded at common law upon the trial of criminal issues as a matter of policy but allowable in the cross-examination to credit of an ordinary witness. It follows that in so far as the questions excepted to in the case of the present applicant were relevant to the issues they were not excluded by the operation of s. 399 (e). But it is anything but clear that all the questions excepted to are relevant to the proof of guilt. On the contrary the connexion between the issues and some matters put to the accused is tenuous in the extreme and in others the connexion does not exist. It is needless, however, to pursue in detail this divergence; for this is an application for special leave to appeal and we must be guided by the principles which govern our discretion to grant such application. It is enough to say that the evidence properly received against the applicant possessed great probative force and raised a strong presumption of guilt and the questions asked of him which ought not to have been allowed, when weighed with the evidence against him, could have no logical operation in persuading a reasonable man of his guilt and moreover, in the circumstances, are unlikely in fact to have played any part in influencing the verdict.
