[15] The power to make an order must be exercised for the purposes for which that power is conferred. The purpose of the rules generally are "to facilitate the just and expeditious resolution of the real issues in civil proceedings at a minimum of expense", the rules are to be applied "with the objective of avoiding undue delay, expense and technicality and facilitating" that purpose, and each party "impliedly undertakes to the court and to the other parties to proceed in an expeditious way": r 5. That r 374 confers a power to give a judgment which will preclude a judicial determination of issues joined between the parties requires that power to be exercised with caution, but r 5 makes it clear that the relevant considerations must include those which bear upon the question whether an applicant under r 374 is being vexed by a respondent who is unwilling or unable to proceed with the expeditious disposition of the litigation. In considering that question, it is relevant to take into account, as was held in Johnson v Public Trustee of Queensland as executor of the will of Brady (deceased), the "financial and personal strain imposed on litigants, witnesses and other parties who are affected by a party's failure to comply with a court order without adequate explanation or justification", the circumstance that the party applying for the order was put to substantial costs, the absence of any assurance that those costs would be recoverable from the party in default, and the absence of any indication by the party in default "as to how and when, if ever, she would comply with Court directions to file affidavits in a proper form in relation to her assets."[5]
