46 In my view, the decision of Gibbs J is not authority for the proposition that, in all circumstances, the evidence of a witness on a particular matter must be accepted if the witness was not cross-examined on that point. One explicit exception is where the evidence is inherently incredible. Further, his Honour considered that the tribunal of fact was entitled to draw a conclusion contrary to the view expressed by the witness on the basis that the witness may have changed her mind about working until 55 years of age, or her circumstances may have altered. Certainly, these factors do not pertain to the relevant fact in issue in this case, which is the respondent's intention at the time he carried the spanner towards the car. However, it is clear from the decision of Gibbs J in Precision Plastics Pty Ltd v Demir that, ultimately, the question of whether the evidence is to be accepted is for the tribunal of fact and certain factors may allow the tribunal of fact to reach a contrary conclusion, notwithstanding the absence of cross-examination. Gibbs J did not attempt to set out all the circumstances in which a tribunal of fact might be entitled to reject the evidence of a witness who has not been cross-examined on that evidence. Yet if factors in that case entitled the jury to reject the witness's evidence, or at least to decline to act upon it, I can see no reason why circumstances in other cases would not entitle the court to reject the untested evidence of a witness. However, in view of the statement of principle that a jury, acting reasonably, were bound to accept the evidence as it was uncontradicted and unchallenged in cross-examination, the rejection of such evidence would necessarily be uncommon.
