For a complaint in a sexual offence case to be admissible in evidence, it must satisfy two cumulative requirements: (1) the complaint must be made voluntarily, not as a result of questions of a leading, inducing or intimidating nature; and (2) the complaint must be made without undue delay, at the earliest reasonable opportunity, to the first person to whom the complainant could reasonably be expected to make it. A complaint induced by threats of physical assault fails the voluntariness requirement and is inadmissible. Once complaint evidence is inadmissible, if it forms the foundation of the state's case, the prosecution cannot succeed. Even after abolition of the cautionary rule in sexual cases, courts must carefully assess whether the complainant has told the truth, examining the evidence for consistency and probability.
