If a responsible authority refuses to consent, an application for review can be made under section 149 of the Planning and Environment Act 1987.
22 Whilst there are important limitations on the ambit of the authority that may be exercised under secondary consent provisions, there are no limits to the extent of an amendment of permit that may be applied for under section 72. There is no suggestion that only 'minor' amendments are envisaged. The notice and review provisions ensure that persons affected and referral authorities will be given an opportunity to participate in the decision making process.
23 The benefits of enabling permits to be amended are many. The process recognises that a permit holder's plans and needs may change over time in response to matters such as changed economic conditions, changes in technology or operating procedures, more detailed site investigations (such as occurred in Maher's case) or simply because a permit holder has changed his mind. Being able to amend a permit avoids the need to reopen all the issues associated with the permit and focuses only on the amendment itself. It also avoids the proliferation over time of permits for different aspects of the use and development of a single site.
24 However, as noted previously, division 1A does not apply to a permit issued at the direction of the Tribunal. A permit may be issued at the direction of the Tribunal in circumstances arising from a refusal by the responsible authority to grant a permit; a failure to grant a permit; a review by objectors of the decision of the responsible authority to grant a permit; or an application by the permit applicant to review conditions in a permit. The review does not need to have been at the instigation of the permit holder, for example an objector's review under section 82. However, application of the test as to what constitutes a material change of circumstances as formulated in Maher's case would severely disadvantage the holder of a permit that had been issued by direction of the Tribunal. It would force them to apply for a new permit when perhaps only a very minor change to a condition was required. This is a waste of resources. It is also inequitable that permit holders whose permits may have been issued at the direction of the Tribunal for any reason should not have the same opportunity to amend their permits, if appropriate, as other permit holders whose permits have not been the subject of a Tribunal review.
25 It does not seem reasonable to assume that parliament intended to create inequities between permit holders depending upon whether or not their permits had been issued at the direction of the Tribunal. We consider that the amendment of section 87 at the time when division 1A was introduced into the Act indicates an intention on the part of parliament to ensure that any permit holder would have an opportunity to seek amendment of a permit either under section 72 or section 87.
26 Requiring an application to be made under section 87 directly to the Tribunal in circumstances where a permit has been issued at the direction of the Tribunal, avoids the situation whereby conditions that might have been specifically included by the Tribunal could be deleted by the responsible authority perhaps without regard to the reasons for their original inclusion. It avoids the potential to 'undo' the effect of a Tribunal decision, whether deliberately or otherwise. It safeguards the efficacy of Tribunal decisions yet still allows permits to be amended in the same way as under section 72 except under the auspices of the Tribunal. Adequate opportunities are provided in division 3 to ensure that persons with a material interest in the outcome of a request under section 87 are given an opportunity to be heard at the hearing of the request, just as potentially affected people are provided with notice of an amendment under division 1A.
27 Division 3 is intended to apply to the cancellation and amendment of permits at the request of various people not just permit holders. Therefore, many of the grounds referred to in section 87(1) will not necessarily be relevant to requests for amendments by permit holders. The most likely grounds upon which a permit holder will apply to amend a permit is section 87(1)(d) - a material change of circumstances which has occurred since the grant of the permit. On its face, this is a most comprehensive ground. It has been read down by previous Tribunals as previously outlined, and Maher's case probably represents the most restrictive approach it has been given. We do not consider that a sound planning justification remains for maintaining such a narrow interpretation of section 87(1)(d) in light of the changes which have been subsequently made to the Act and the wider opportunities now available to permit holders to apply for amendments to permits.
28 For these reasons, we consider that it is open to the applicant in the present case to rely upon section 87(1)(d) in making this request to the Tribunal to amend permit MPS2002/0010. We consider that the decision of the Tribunal in Hasan v Moreland CC[8] amounts to a material change in circumstances. Hasan's case was conducted as a hearing likely to result in a 'guideline' decision because the application for review had the potential to have broad implications throughout Victoria. The presiding member was the President of the Tribunal, Justice Stuart Morris, and observations were made about the weight to be given to the decision in future cases:
