Evidence Act 1906

If a court is satisfied that particular evidence that a party to a proceeding proposes to adduce is so voluminous or complex that it would be difficult to assess or comprehend it if it were adduced in narrative form, the court may direct the party to adduce the evidence in another form, including in the form of a chart, summary or other explanatory document.

The direction may also —

specify the form of the evidence;

specify the witness who is to give the evidence;

specify how any document is to be prepared;

contain directions to ensure that each other party is served with copies of the evidence in the form in which it is to be given and is given sufficient time to examine it;
