Section 405C(2) has brought about the result that women are no longer, in the eyes of the law, to be put before juries as persons whose evidence requires corroboration before it is safe to act upon it. That concept which has been in the law for a long time has now gone. That, of course, does not mean that a judge cannot draw attention to the absence of corroborating testimony from witnesses who are shown by the evidence to have been present and able to offer corroboration of the girl's story, if it were true, nor does it preclude the judge from making such observations as he considers ought to be made about the credibility of the complainant's evidence, but always with the proviso, of course, that he must make it clear to the jury that those are his opinions and that the weight to be given to the testimony of the woman is entirely a matter for the jury. The fact that a judge does not comment upon the absence of corroboration of the complainant's evidence cannot, in my view, in the case of those offences to which s 405C applies now be made the basis of a criticism of his summing-up, but again this does not mean that the judge cannot or should not, as is done in all cases of serious crime, stress upon the jury the necessity for the jury to be satisfied beyond reasonable doubt of the truthfulness of the witness who stands alone as proof of the Crown case. In all cases of serious crime it is customary for judges to stress that where there is only one witness asserting the commission of the crime, the evidence of that witness must be scrutinised with great care before a conclusion is arrived at that a verdict of guilty should be brought in; but a direction of that kind does not of itself imply that the witness' evidence is unreliable.
