This passage was criticised by Mr Priest; in particular, he said it reversed the onus of proof. Talk in a criminal case of presumptions arising from proof of a particular relationship, which require evidence of exceptional factual circumstances to raise a reasonable doubt, does, as Mr Priest submitted, and as the dissenting judgment shows, tend to raise concern. With all respect to the majority justices in Audet, by whose discussion of a number of questions I have been much assisted, I would not myself analyse the matter in terms of a presumption. But I am much attracted by the approach which lies at the base of the majority judgment. This is the view that, generally speaking at all events, "it cannot be concluded that a teacher is not in a position of trust and authority towards his or her students without going against common sense". Turning to the words of the Victorian section, I think it may be said that, generally speaking, it would be contrary to common sense to conclude that a teacher who regularly taught a pupil did not have that pupil under his or her care, supervision or authority. But, I repeat, I would not deal with the matter in terms of presumptions, or of exceptional circumstances which raise a reasonable doubt. It is for the Crown to prove all elements of the offence beyond reasonable doubt. Taking the present case, I think that a reasonable jury, properly instructed, ought to have entertained no reasonable doubt that, as regards "school occasions", the relationship required by s.48 existed. The contrary has not been contended by Mr Priest, and, as I have said, the applicant's case, both at the trial and before us, has tacitly made that concession. How is one to square the view that, generally speaking, to deny the relationship of care, supervision or authority as regards school occasions would be against common sense with the rule of the criminal law about burden of proof and with the constitutional role of the criminal jury as the trier of issues of fact? In the present case, had the sexual activity taken place during school hours, it would have been wrong for a properly instructed jury not to conclude that the offence had been proved. But can a judge ever say something like that to a criminal jury? Compare the discussion in R. v. Faure[30]. Nowadays, where identity is the only issue, bold judges might be tempted to tell the jury, in the case of a very violent bank hold-up, that they need not trouble themselves with the definition of armed robbery, since it is quite clear that one was committed, and that the only issue for them is that of identity. There is a similar temptation in cases of undoubted rape, where the only issue is identity. But such bold judges are few and far between, if they exist at all. On a murder trial, notwithstanding that the body has been hacked into six pieces, the judge will like as not solemnly tell the jury that there seems to be no doubt about the element of death, "although it is a matter for you". Even in 1935, in a case in which the victim was indisputably dead, we find Finlay, J. using the familiar words, with the addition of "entirely":
