Judicial Control of Cross-examination
12 The right to cross-examine a witness, at least in a civil case, is not unfettered. It is controlled by the trial judge, not by the litigants or their legal representatives. There are times when a judge will be justified in curtailing a cross-examination. This will usually be done by giving notice and imposing a time limit on the remainder of the cross-examination. The smooth operation of lengthy and complex civil cases depends on sensible co-operation by counsel. It sometimes requires, for its efficient operation, compromise and restraint in the advancement of a party's case. More importantly, it invariably requires judgment. This includes recognition that, in some cases, and with some witnesses, cross-examination can have a limited utility.
13 Unduly lengthy, ineffective or unnecessary cross-examination can be a significant factor contributing to delay and unwarranted cost: Fried v National Australia Bank (2000) 175 ALR 194 at 197-198 per Weinberg J. The Law Reform Commission of Western Australia has identified it as a significant problem, stating, among other things, that unduly protracted cross-examination "increases the time and expense of litigation without assisting justice to be done in the particular case": The West Australian Law Reform Commission, Review of the Criminal and Justice System in WA: Project No. 92, Consultation Paper, Volume 2, Curtailing Irrelevant or Unduly Protracted Cross-Examination & Testimony, Section 3 (3.2) (June 1999).
14 Mahoney JA explained the appropriateness of judicial intervention in the cross-examination process in Government Insurance Office (NSW) v Glasscock (1991) 13 MVR 521 at 529-530 in the following terms:
It is also appropriate for a judge to intervene, to an appropriate extent, where the conduct of the case for one party is less adept than the needs of justice require. If a judge feels, after appropriate time and consideration, that the position of a party is unacceptably prejudiced in this way, he may, I think, suggest, or even ask, the necessary questions.
… It will be appropriate for a judge to ensure that unnecessary time is not wasted or cost incurred. The principles of judicial administration require that the procedures of the justice system be effective, efficient and timely. They are to be effective in the sense of bringing to an end the dispute with which they deal. They are to be efficient in the sense of using for the purpose no more resources than are appropriate. And it is necessary that what is to be done be done in due time.
