[43] White J observed that this remained a correct statement of the relevant principles after Queensland v JL Holdings Pty Ltd (1997) 189 CLR 146. ( Jeans v Commonwealth Bank of Australia [2003] FCAFC 309; (2003) 204 ALR 327 at 330-331; Silver v Dome Resources NL [2005] NSWSC 265 at [8]-[9]). His Honour continued:
'56. ... In Jeans v Commonwealth Bank of Australia , the Full Court of the Federal Court said that there was no principle that admissions might or might not be withdrawn, but that the court had a broad discretion to weigh up all matters, with the overall question being to ensure there was a fair trial. (At 330 [18]). Nonetheless, I approach the task of assessing what fairness to the parties requires, guided by the principles expounded by Santow J in Drabsch . It is legitimate and it may be necessary to consider whether the party making the admission did so deliberately, or whether he did so in error, whether the significance of the admission has changed since it was made, for example by reason of other amendments, ( Silver v Dome Resources NL at [12]), or whether new evidence has come to light. In this case there is no suggestion that the admission was made in error. There has been no change to the pleadings which has altered the significance of the admissions. It is not suggested that new evidence has come to light which justifies their withdrawal. Where a party, who is legally advised and does not suffer any disability, deliberately and without mistake, admits liability in whole or in part, and there are no relevant changes of circumstance, prima facie, justice or fairness to both parties does not require that it be allowed to change its mind. That is why admissions made with deliberateness and formality are not ordinarily permitted to be withdrawn.'
[44] His Honour later referred to a Queensland case Rigato Farms Pty Ltd v Ridolfi [2000] QCA 292; [2001] 2 Qd R 455, where De Jersey CJ said this:
'Fulfilling procedural requirements will often contribute significantly to securing an ultimate result which may be considered just. Allowing the appellant to withdraw these deemed admissions would substantially erode the beneficial worth of a very important procedural mechanism directed, through expediting cases and reducing costs, to promoting the interests of justice.'
[45] McPherson JA, in the same case, emphasised that, in permitting an admission to be withdrawn, the Court should be satisfied that there was a genuine dispute, and that would ordinarily require an explanation of how the admission came about. White J quoted the following passage from that judgment:
'Before permitting the admission to be withdrawn, the first step to be determined here was whether there was a genuine dispute about the defendant's liability in this action. ... it is not enough for that purpose simply to assert that a dispute exists: ...Some proper basis must be laid for that assertion, which would ordinarily include an explanation of how the earlier admission came to be made and why it should now be permitted to be withdrawn. That is not shown by a (sic) saying simply that there has been a change of solicitors, or that it is possible to see that, before the admission was made, the issue of liability was an open question. Here the defendant has not condescended to swear to the circumstances in which the admission came to be made, or to show that it occurred by inadvertence, mistake or in some other way that might now justify its withdrawal.'
[46] I was also taken to the decision of the Federal Court in Re Rocco Celestino v Antonio Celestino [1990] FCA 299 and especially paragraphs 12 to 14; and Coopers Brewery Ltd v Panfida Foods Ltd (1992) 26 NSWLR 738 (Rogers CJ Comm D)."
9 The proposed amendment to the Points of Defence consequential upon the proposed withdrawal of the admissions should also be considered in light of the principles in ss 56-61 of the Civil Procedure Act 2005 and the decision of the High Court in Aon Risk Services Australia Ltd v Australian National University [2009] HCA 27, 239 CLR 175 which was decided in the context of similar rules in the Australian Capital Territory. Section 56(1) provides that the overriding purpose of the Act and of the Rules of Court in their application to civil proceedings is to facilitate the just, quick and cheap resolution of the real issues in the proceedings. Section 56(2) mandates that the Court must seek to give effect to the overriding purpose when it exercises any power given to it by the Act or by rules of Court or when it interprets any provision of the Act or any such rule. In Aon the trial judge granted the plaintiff leave to amend its statement of claim to introduce a new and substantial claim. The High Court allowed an appeal against the decision.
10 The respondents simultaneously with their applications to withdraw their admissions seek leave to amend their Points of Defence by, in the case of the Panel, simply denying paragraph 12 of the Further Amended Points of Claim and, in the case of Hyecorp, pleading that it "denies the Development involved carrying out of any work of a permanent character on the area reserved for the county road widening under cl 13(1) of the KPSO".
