Second Respondent's submissions
11 The Second Respondent argued it would suffer irreparable prejudice if the amendment is allowed for two "forensic" reasons.
(i) Section 101 of the Environmental Planning and Assessment Act 1979 (the EP&A Act) cannot be relied upon if this amendment is allowed as the amendment is deemed to date from the commencement of the proceedings which were within the three months specified in s 101. If fresh proceedings were commenced now, based on the findings in RAID, s 101 would be able to be raised to bar the proceedings.
(ii) Had this case been pleaded before August 2006 the Second Respondent could have sought to remedy its position by lodging new development applications for the current developments supported by an environment impact study (EIS). It has now lost that opportunity as such development is now prohibited under the amended local environmental plan (LEP).
12 The ground sought to be added could have been raised at the outset of proceedings and the issue dealt with as it was in RAID.
Applicant in reply
13 The Applicant argued that the s 101 argument is irrelevant because these proceedings were commenced within time in terms of s 101 and the uncertainty occasioned by this challenge to the development consent has already arisen regardless of whether the amendment now sought is made. In other words, there is no greater uncertainty occasioned by this amendment to the pleadings than already exists.
14 In relation to the lost opportunity to make application for fresh development consents, whether such an application would succeed cannot be assumed, contrary to the Applicant's submissions that its approval was likely.
Finding
15 The Court has wide discretion under Pt 10.1 of the Court Rules to allow amendments at any stage of the proceedings. Dawson Gaudron McHugh JJ in Queensland v JL Holdings Pty Ltd held at 155:
Justice is the paramount consideration in determining an application such as the one in question. Save in so far as costs may be awarded against the party seeking the amendment, such an application is not the occasion for the punishment of a party for its mistake or for its delay in making the application. Case management, involving as it does the efficiency of the procedures of the court, was in this case a relevant consideration. But it should not have been allowed to prevail over the injustice of shutting the applicants out from raising an arguable defence, thus precluding the determination of an issue between the parties. In taking an opposite view, the primary judge was, in our view, in error in the exercise of her discretion.
