22. The Applicant for Review, conscious of at least some of the difficulties arising from this uncertainty, has proposed a new set of plans which it seeks to have endorsed pursuant to condition 1 of the permit. In fact these plans are the subject matter of the second proceeding before me namely the referral under what is now s.149 PE Act. The Applicant for Review, having asked the Responsible Authority to approve the plans pursuant to that condition, referred the matter to the Tribunal under what is now s.149 when the Responsible Authority failed to determine that question. The plans so referred are materially different to the endorsed plans which I am invited to take to be the endorsed plans for permit S1342. Although approval of these endorsed plans might clarify the uncertainties referred to in the 10th ground of the application for review, a far more appropriate way of pursuing a development in that form would be for the Applicant for Review to make a new permit application to the Responsible Authority based on those new plans. That would enable a fresh assessment of what is really a new proposal, according to the procedures and protections afforded by the PE Act. It seems to be quite inappropriate to try and graft this new proposal on to the ancient stock of permit S1342. Such a new proposal would be considered and assessed in the light of present circumstances including the physical circumstances of the land and surrounding land, the present planning scheme provisions as they have evolved since 1990 and present planning policies. They have been a number of amendments to the planning scheme and planning policies that are relevant to this property since 1990. Such changes, if relevant to the existing permit, are very powerful considerations against granting a further extension after all this time. Mr Canavan has sought to avoid this adverse result (from the point of view of his client) by suggesting that these various changes, enumerated by Mr Pitt, are not in fact relevant to the permitted proposal. This would be well and good if that proposition was simple and obvious, but it seems to me that I am confronted with a rather difficult, complex and uncertain exercise in trying to distinguish whether any and which aspects of these changes are relevant. These difficulties can be conveniently, and I think suitably, avoided if a new permit was to be applied for. Such an application would be assessed on its merits and on the basis of present circumstances without the need to go back eight years and try and assess a series of changes that have occurred in the meantime.
