However, the applicant does not raise or rely on the failure of the judge to instruct the jury as to the effect upon the credibility of the prosecutrix of a failure to complain. His counsel submits that as a matter of law a judge on a trial of an accused for rape is bound in every case to instruct the jury, no matter what the circumstances, that the failure to make such a complaint is evidence of consent by the woman to the intercourse. The submission is founded on the proposition that because evidence of proximate complaint is evidence, as it was said, that the woman had not consented, the lack of complaint must be evidence of consent. But, in my opinion, even granting the premises, the conclusion does not follow. Further, evidence of a complaint at the earliest reasonable opportunity is exceptionally admitted only as evidence of consistency in the account given by the woman claiming to have been raped: that is to say, it is admitted as matter going to her credit (see Reg v Lillyman, per Hawkins J. [1] ; Sparks v The Queen [2] ). Because the account with which the complaint is said to show consistency is an account of intercourse without consent, it has often been said that the evidence of the complaint is evidence negating consent. In my opinion, this manner of expressing the function of the evidence of proximate complaint is not correct: though, as it shows consistency in her account of rape, the fact of the complaint buttresses her evidence of no consent or, as it was said in Reg v Lillyman [3] , is inconsistent with consent. At times also it is said with technical inaccuracy that the evidence of such a complaint is corroborative of the woman's evidence of the rape. It is quite clearly not so corroborative (see R v Christie [4] ; Eade v The King [5] ), though it is so spoken of in American literature (see Wigmore on Evidence, 3rd ed. (1940), vol. IV, p. 219, par. 1134 and p. 227, par. 1137; vol. VI, p. 173, par. 1761).
