136 Despite his Honour's observation that he 'could see no point in repeating conditions in the access arrangement already contained in the license', the parties were agreed that the effect of the determinations which his Honour made, in [2] of the Alcorn determination, for example, was to incorporate as conditions of the access arrangement, all of the conditions imposed in the licence, including those contained in the 'Exploration Environmental Management Plan for the Caroona Project'.
137 The plaintiffs did not seek to appeal this aspect of the determination, but used it to illustrate that by adopting this approach, his Honour had refused access conditions which were 'matters of concern that are raised by individual landholders', going to the detail of how, for example, drilling was to be conducted on the particular sites on their property to which the defendant sought access. The plaintiffs had sought that various conditions be imposed in relation to such drilling, because the licence conditions were stated in broad terms, rather than specifying how those obligations were to be met, in the circumstances of the particular sites to which the defendant sought access on their land.
138 The parties joined issue on those matters before the Mining Warden. The defendant called evidence as to 'precisely how it intended to drill on the plaintiffs' land'. Expert evidence was called which went to the risk of contamination of both water aquifers and the land, which might be posed by such drilling at the particular sites to which the defendant sought access. There were differing views initially amongst the experts. In the case of an expert commissioned by the Caroona Coal Project Community Consultation Committee (whose report was received over the objections of the plaintiffs), the opinion expressed was that 'there is no evidence that exploration drilling for coal could damage aquifers, provided that procedures outlined in the above documents are adopted'. These were the defendant's documents.
139 The experts called by the parties conferred and a consensus emerged. Firstly, that the risks which drilling posed was relatively small and secondly, how drilling should be conducted in the particular conditions pertaining to the sites on the plaintiffs' properties to which the defendant sought access, in order that those risks be addressed. Despite this, his Honour declined to impose conditions in relation to drilling to reflect the consensus which had emerged from the experts. The result was that the defendant was not bound to abide by the views to which the experts had come in relation to drilling at the sites on the plaintiffs' land, during that course of the review proceedings as to the issues in contest.
140 The parties joined issue over the method of drilling in a context where there was a concern that the exploration which the defendant intended to pursue gave rise to the risks of aquifer and land contamination resulting from the drilling process. The defendant's expert's evidence was that while the risks were small, if it occurred, contamination was difficult to detect. If there was contamination to the land, which came to the notice of the plaintiffs, there would be an immediate right to refuse access, until the breach was remedied, if the contamination resulted from the defendant's breach of an access condition. If contamination was the result only of a breach of a licence conditions, all that the plaintiffs could do would be to draw the contamination to the attention of the Minister, in the hope that the Minister would agree that a licence condition had been breached and that action would be taken in respect of the breach. If the Minister refused to take action, all that the plaintiffs would be left with, would be a right to seek compensation.
141 The reasons given by the Mining Warden for the refusal of the access conditions sought in relation to drilling, was that he could see no reason why such conditions should be imposed, given his view that they were adequately dealt with in the licence conditions and associated obligations. The point of the expert evidence was, of course, to delve into particular matters pertaining to the sites in question, which were not dealt with specifically in the licence conditions, as s 141 contemplated. To my mind there can be no question that his Honour misunderstood the statutory scheme in this respect, with the result that he erred in the approach adopted to the resolution of the contest over the access conditions to be imposed upon the defendant.
142 I am satisfied that his Honour was undoubtedly correct to refuse some conditions proposed by the plaintiffs, for example a condition that drilling be subject to an opinion from an independent hydro-geologist, who could impose further conditions. The Act does not envisage such a devolution of the Warden's Court functions.
143 In so far as his Honour came to the view, however, that there 'was no point' in an access condition dealing with matters already dealt with in licence conditions such as those dealing with drilling, his Honour plainly erred in his understanding of the statutory scheme. Under the Mining Act there would be a very substantial, practical point in a landholder succeeding in having an access condition imposed in relation to how drilling was to be conducted at a particular site on the property and a licence holder resisting the imposition of any condition at all. If the result of a conclusion that a specific condition should be provided was inconsistent with any broad licence condition, the licence condition would prevail. Otherwise, contravention of the specific access condition would give the plaintiffs the right to refuse the defendant access to the land, until the contravention ceased.
144 Undoubtedly, whether or not any particular access condition directed to precluding contamination as the result of the drilling process adopted should be imposed was a matter for the Mining Warden to determine as a matter of discretion, but it was a discretion which had to be actively exercised in accordance with the dictates of the statutory scheme.
145 His Honour's decision that to refuse to impose the access conditions sought, because there was no point, once he had imposed all licence conditions as access conditions, involved error. It expanded the right to refuse access for breach of any licence condition from a right only lying in the Minister, to one given to all landholders. It is impossible to see that this accorded with the scheme of the Act. Nor seemingly, had it been sought by the plaintiffs. The exercise of the discretion arising under s 141 required that the matters on which the parties had in fact joined issue be considered and determined, whether or not they related to matters the subject of conditions in the license. Under the statutory scheme, the plaintiffs' claims could not be dismissed without explanation, or on the basis of a view that there 'was no point' in providing for access conditions which touched on areas already dealt with in licence conditions.
