Uniform Civil Procedure Rules 1999

The court may order a party be relieved, or relieved to a specified extent, of the duty of disclosure.

Without limiting subrule (1), the court may, in deciding whether to make the order, have regard to the following—

the likely time, cost and inconvenience involved in disclosing the documents or classes of documents compared with the amount involved in the proceeding;

the relative importance of the question to which the documents or classes of documents relate;

the probable effect on the outcome of the proceeding of disclosing or not disclosing the documents or classes of documents;

other relevant considerations.
