76 The reasons of the delegates, without annexures, run to some 19 pages. They adequately summarise the draft amendment, its intended objectives and its effects. They deal with each criterion and state the objections to each, including the material and critiques set out in the Productivity Commission Inquiry Report entitled Impacts of Native Vegetation and Bio Diversity Regulations. The delegates considered the interrelationship of the proposed management regime and existing Private Tree Reserves and differing statutory provisions, including the Kingborough Planning Scheme, the Bruny Planning Scheme 1986, the Threatened Species Protection Act 1995, the Environment Protection and Biodiversity Conservation Act 1999, the Nature Conservation Act 2002, and the State Policies set out in the State Coastal Policy 1996, the State Policy on the Protection of Agricultural Land 2000, and the State Policy on Water Quality Management 1997. The delegates analysed each of the thirteen criteria for a subdivision required by the amendment cl 9.4.2.1(b), set out in Table 9.1. They dealt with the objections advanced by the opponent representors, made some amendments to the draft, and in some instances identified further amendments or assessments necessary if the Council wished to pursue certain matters such as boundary adjustment or in the implementation of the scheme. The reasons were thorough, disciplined and wide-ranging. The appellants had the opportunity to advance other material or reasoning through the first appellant and can show no significant matters not raised or dealt with by the delegates. An artificial or theoretical construct that something else might have been advanced by another person who might have appeared, did not prevent the learned primary judge from making the finding, if such is the import of his statement. He was not precluded, in the exercise of discretion, from either declining to take the construct into account or concluding that no other reasonable argument was apparent. This ground ought fail.
