Northern Territory Consolidated Acts Northern Territory Consolidated ActsIn deciding whether any question affecting the credibility of a witness is relevant, or ought to be allowed, the Court shall have regard to the following considerations:
(a) The question is proper if it is of such a nature that the truth of the imputation conveyed by it would seriously affect the opinion of the Court as to the credibility of the witness on the matter to which he testifies;
(b) The question is improper if the imputation which it conveys relates to matters so remote in time, or of such a character, that the truth of the imputation would not affect, or would affect in a slight degree, the opinion of the Court as to the credibility of the witness on the matter to which he testifies;
(c) The question is improper if there is a great disproportion between the importance of the imputation made against the witness's character and the importance of his evidence.
