No objection was taken to these questions at the time, but the asking of them gave rise to one of the grounds of appeal to the Court of Appeal [1] . Brooking JA, speaking for a unanimous Court of Appeal, rejected this ground, saying:
Mr Kent submits that this cross-examination of his client was impermissible, but, whatever the position might have been had the complainant herself not been cross-examined about motive to misrepresent (and as to this I express no opinion), the applicant had chosen to raise that matter and cannot complain that it was taken up by the Crown Prosecutor when she came to cross-examine the applicant. Again, I might interpolate, there was no objection taken at the trial to this cross-examination.
The question which had been put to L in cross-examination attributed to her a motive to lie, namely, "pay back" or revenge. Cross-examination is permissible and evidence is admissible to establish that a complainant has a motive to make and persist in false allegations. Thus it is said in Wills on Circumstantial Evidence [2] :
It is frequently therefore of the highest importance to investigate the motives of the complainant, and to ascertain whether they are such as may have led to the institution of a false charge. The just course of inquiry in such circumstances was thus laid down by Mr Justice Cresswell. "The jury," he said, "had nothing to do with the prosecutor's motives except so far as if it should appear that there was any motive for the prosecution of an unworthy character made out, it would then be their duty to watch such a case much more narrowly than one in which no such motive appeared. Even in that case, however, if the evidence satisfied them of the truth of the charge, they had no right to look at the motives that had induced the prosecutor to prefer it, but were bound to say that the accused person was guilty" [3] .
In R v Uhrig [4] Hunt CJ at CL said:
A motive to lie where it does exist is a very relevant factor in judging a witness's credit. It will almost inevitably have substantial probative value in relation to the issue of credit, and so will pass the test posed by s 103 of the Evidence Act 1995 for admissibility. If the alleged motive is denied by the witness, other evidence may be led to rebut that denial in accordance with s 106.
1. Ground 2: "The trial of the applicant miscarried in that the applicant was cross examined by the prosecutor as to whether the complainant had any motive to make her allegations."
