Unsatisfactory though its historical rationale may be, it is an entrenched principle that evidence of early complaint is admissible in rape cases, but "only as evidence of consistency in the account given by the woman claiming to have been raped; that is to say, ... as matter going to her credit": Kilby v. R. [1973] HCA 30; (1973) 129 C.L.R. 460, 466, per Barwick C.J., with whom McTiernan, Stephen and Mason JJ. agreed; see also per Menzies J., with whom Mason J. also agreed, at pp. 473-474. As was pointed out by Gaudron J. in M. v. R. [1994] HCA 63; (1994) 126 A.L.R. 325, 344, in prosecutions for sexual offences evidence of early complaint is "admissible whether the victim is male or female, but, more often than not, the principle has been stated with respect to women and girls, as has its rationale". The principle is based on male assumptions, in earlier times, concerning the behaviour to be expected of a female who is raped, although human behaviour following such a traumatic experience seems likely to be influenced by a variety of factors, and vary accordingly. Presumably for that reason, the law in some places has been altered by statute; e.g. New South Wales, where s. 405B was inserted into the Crimes Act 1900 by the Crimes (Sexual Assault) Amendment Act 1981. See, further, M. v. R. at pp. 344-345.
