“41. . . . it is open to a judge to guard against abuse of the system. The defence, wishing to put questions about alleged previous false complaints, will need to seek a ruling from the judge that section 41 does not exclude them. It would be professionally improper for those representing the defendant to put such questions in order to elicit evidence about the complainant’s past sexual behaviour as such under the guise of previous false complaints. But in any case the defence must have a proper evidential basis for asserting that any such previous statement was (a) made and (b) untrue. If those requirements were not met, then the questions would not be about lies but would be “ about [the] sexual behaviour of the complainant” within the meaning of section 41(1). The judge is entitled to seek assurances from the defence that it has a proper basis for asserting that the statement was made and was untrue.”
“22. The difficulty lies in what constitutes a proper evidential basis. In our judgment, it is less than a strong factual foundation for concluding that the previous complaint was false. But there must be some material from which it could properly be concluded that the complaint was false. In Garaxo at paragraph 14 this court considered that there was a proper evidential basis if there was material such that, depending on the answers given by the complainant in cross-examination, the jury could have been satisfied that the previous complaint was untrue, or there was material which was capable of founding an inference that the complaint was untrue. . . . 25. It is a striking feature of this case that the judge did not ask himself whether, on the material before him, depending on the answers given by the complainant, the jury could have been satisfied that the previous complaint was false. That is what was entailed by the question whether there was a proper evidential basis for the assertion that the complaint was false. If the judge had focused on the question whether on the material before them the jury could have been satisfied that the complaint was false, he should have concluded that the jury could have been so satisfied. As Sweeney J. said in the course of argument, there were a number of features relating to the previous complaint which could have led a jury to this conclusion. First, there was the interval of four months between the date of the alleged rape and the date when the complainant reported it to the police. Secondly, there were aspects of the complaint which were puzzling and which caused the investigating police to be sceptical: some of them merit separate mention, but, for example, the police thought it was strange that, according to her account, the complainant had not seen the alleged attacker since the date of the alleged offence although they were members of the same circle of friends. It is also to be noted that on page 2 of the Crime Investigation Plan the police listed a series of questions that they would have wished to ask the complainant about her account in order to test it. Thirdly, there is the fact that the complainant did not follow through with her complaint and would not allow the police to pursue an investigation into what was, if her account was true, a very serious offence. Fourthly, the complainant was willing to give the police only sufficient information to enable her to achieve her goal of being re-housed. Her desire to be re-housed, which was her motive for reporting the matter to the police, raised questions as to her true reasons for making that report.”
