3 There is some authority for the proposition that a respondent to an application to set aside a judgment may waive the right to object to the proceedings being entertained by a motion or an application in the action in which judgment has been entered, eg, Ainsworth v Wilding (supra) at 679, but in Spies v Commonwealth Bank of Australia (1991) 24 NSWLR 691 where the basis for setting aside the judgment was alleged to be fraud, Handley JA, at 701, urged caution in departing from the established practice of determining such issues by way of a fresh action. Even in Ainsworth v Wilding (supra), Romer J, at 680, acknowledged the desirability of not dealing with them on motion "when, from the nature of the ground on which the application was based, conflicting evidence would have to be gone into or viva voce evidence and cross-examination would be essential". To this could be added the advantage of undertaking orderly discovery and interrogation in a separate action. However, in the circumstances of this case, the defendants, who are respondents to the application, are not prepared to waive their right to object.
