It is my view that the words "or other valuable work or structure" are included to give the chief mining warden a wider discretion to include other items which are not specifically listed in s 62(1) (c). I also agree with the chief mining warden that Parliament used the word "or" to create a disjunctive phrase so that the word "valuable" does not refer to the preceding phrase."
16 Mr AJ Meagher SC, learned Senior Counsel for the appellant, levelled certain criticisms at this reasoning. In the main, they were justified. He submitted that the word "substantial" must qualify all subsequent nouns, which is normal English usage. I agree. This is all the more so when one considers the bizarre results which one would obtain if, as the Warden and the Master held, "substantial" qualified the word "building" alone: an insubstantial building would not be an "improvement", but an insubstantial levee would. Again, Mr Meagher seems to me to be justified in his submission that the Warden invented a test of his own as to the meaning of the word "improvement", viz. whether the object in question fulfilled the intention for which it was designed. There is no statutory warrant for this test.
17 However, he also submitted that the words "or other valuable work or structure" were to be construed as referring to, and only to, the words "dam, reservoir, contour bank, graded bank, levee, water disposal area, soil conservation work", these constituting a genus to which " or other valuable work or structure" belonged. This submission should be rejected. There is no need to mangle the words. There is no reason why "other" should not refer back to "building" as well as to the other nouns. And if it did not, one would have the odd result that objects like a bore would not constitute an improvement. As a matter of English, the wording of paragraph (c) of s.62 (i) requires such of the objects listed to be both "substantial" and "valuable", not withstanding that this involves a certain measure of tautology.
18 Mr Meagher also contended that the expression "value" implicit in the words "valuable work or structure" should be understood as referring to works of special value, considerable value; so that the words actually used should be construed as if they were "very valuable work or structure". I see no justification for this.
19 Mr Meagher further contended that the Warden and the Master were in error in holding that the Warden had a discretion to exercise: a thing either is an improvement or is not an improvement. In this, also, I think he was correct.
20 Mr Meagher's contentions were angled at excluding fences from the definition of "improvements". As I understand it, his argument was that fences could not, of their nature, be either substantial or especially valuable; and, moreover, were outside the genus he discussed in the definition of "improvements". The contentions must collapse once one rejects the notion that "valuable" means "especially valuable".
21 The result is that the appellant has demonstrated error in the reasoning of the Warden, and further error in the reasoning of the Master. However, he has not demonstrated any error in the finding that the fences on both the Ducey land and the Casey land were "other valuable works or structures" within the statutory definition of "improvements". Since the appellant seeks relief of a prerogative nature, this Court has a discretion to refuse such relief. If, as I think, there is an unchallengeably correct finding that fences are "improvements", and, if so, not withstanding the errors of the Warden and the Master, there is a statutory prohibition against granting the lease which the appellant desires, there would be no point in remitting the matter to the Warden.
22 In my view the appeal should be dismissed with costs.
23 POWELL JA I agree with Meagher JA.
