Consideration
24 Before considering the appellant's contentions, there is a preliminary question that must be resolved. The jurisdiction of this Court to entertain an appeal from the Tribunal is a narrow one. Section 34(1) of the Administrative Review Tribunal Act provides an appeal by a party to a proceeding before the Tribunal will lie only "on a question of law": see generally Grube v Minister for Lands and the Environment. As Brennan J observed in Waterford v The Commonwealth (1987) 163 CLR 54 at 77 there is no error in law simply in making a wrong finding of fact.
25 It has been stated repeatedly that the magnification and inflation of questions of fact into questions of law to provide an avenue of appeal from decisions of an administrative tribunal "is to be deprecated": see, for example, Blackwood Hodge (Australia) Pty Ltd v Collector of Customs (NSW) (1980) 47 FLR 131 at 143-145 per Fisher J; and Willcocks v Comcare (2001) 66 ALD 119 at 124 per Finn J. See also Neal v Secretary, Department of Transport (1980) 29 ALR 350 at 354-355 per Franki J.
26 In Politis v Federal Commissioner of Taxation (1988) 16 ALD 707 at 708 Lockhart J was critical of what he saw as a growing tendency for the Court "to be asked to construe the Tribunal's reasons for its decision minutely and finally and with an eye keenly attuned to the perception of error". It was that passage that formed the basis of the High Court's celebrated admonition against that very vice in Minister for Immigration and Ethnic Affairs v Wu Shan Liang (1996) 185 CLR 259.
27 There is a distinction between an appeal "on a question of law", as required by s 34(1) of the Administrative Review Tribunal Act, and an appeal that merely involves a question of law. The former is a narrower expression. It involves what has been described as "a pure question of law". A mixed question of fact and law is not a question of law within the meaning of s 34(1). See generally Comcare v Etheridge (2006) 149 FCR 522 at [16]. See also Australian Securities and Investments Commission v Saxby Bridge Financial Planning Pty Ltd (2003) 133 FCR 290 at [47]-[48] per Branson J, and at [107]-[108] per Jacobson and Bennett JJ; and Brown v Repatriation Commission [2006] FCA 914 at [7] per Branson J.
28 The distinction between questions of fact and questions of law is one that bedevils many cases. It also causes problems throughout administrative law generally. There is a helpful discussion of the broader issues raised by this distinction in Collector of Customs v Pozzolanic Enterprises Pty Ltd (1993) 43 FCR 280 at 287 where the Full Court (Neaves, French and Cooper JJ) put forward five general propositions which it regarded as emerging from the cases:
"1. The question whether a word or phrase in a statute is to be given its ordinary meaning or some technical or other meaning is a question of law: Jedko Game Co Pty Ltd v Collector of Customs (NSW) (1987) 12 ALD 491; Brutus v Cozens [1973] AC 854.
2. The ordinary meaning of a word or its non-legal technical meaning is a question of fact: Jedko Game Co Pty Ltd v Collector of Customs (NSW) (supra); NSW Associated Blue-Metal Quarries Ltd v Commissioner of Taxation (Cth) (1956) 94 CLR 509 at 512; Life Insurance Co of Australia Ltd v Phillips (1925) 36 CLR 60 at 78; Neal v Department of Transport (1980) 3 ALD 97 at 107-108.
3. The meaning of a technical legal term is a question of law: Australian Gas Light Co v Valuer-General (1940) 40 SR (NSW) 126 at 137-138; Lombardo v Commissioner of Taxation (Cth) (1979) 40 FLR 208 at 215.
4. The effect or construction of a term whose meaning or interpretation is established is a question of law: Life Insurance Co of Australia Ltd v Phillips (supra) at 79.
5. The question whether facts fully found fall within the provision of a statutory enactment properly construed is generally a question of law: Hope v Bathurst City Council (1980) 144 CLR 1 at 7 per Mason J with whom Gibbs, Stephen, Murphy and Aickin JJ agreed; Australian National Railways Commission v Collector of Customs (SA) at 379 (Sheppard and Burchett JJ)."
29 The Full Court went on to state that the fifth proposition had been elaborated by reference to the remarks of Fullagar J in Hayes v Federal Commissioner of Taxation (1956) 96 CLR 47 at 51 to the effect that where the "factum probandum" involves a term used in a statute, the question whether the accepted "facta probantia" establish that factum probandum will generally, if not inevitably, be a question of law. However, the Full Court then went on to observe that this principle was qualified when a statute used words according to their ordinary meaning and the question was whether the facts as found fall within those words.
30 Critically, the Full Court said (at 288):
"Where it is reasonably open to hold that they do, then the question whether they do or not is one of fact: Hope v Bathurst City Council at 8.
31 The term "concrete", as part of the composite expression "concrete batching plant", is used in its ordinary sense in the Plan. That is borne out by the fact that cl 121(1) requires the meaning of any word which is undefined in the Plan to be taken to be the meaning used in the Shorter Oxford English Dictionary.
32 The definition in the Shorter Oxford English Dictionary refers to a "mixture", but does not stipulate the extent to which the process of mixing must be undertaken before concrete is produced. Likewise, the definition of "concrete batching plant" in cl 121(2) refers to "the mixing" of concrete, but says nothing about how extensive that process of mixing must be.
33 Notwithstanding the fact that the Tribunal did not refer to the definition of concrete in the Shorter Oxford English Dictionary, but chose instead to refer to the definition provided in the Australian Building and Construction Definitions Handbook, the Tribunal did not err in law in doing so. The adjective "thoroughly" is taken from that definition. It gives scope and content to the Dictionary definition and is entirely compatible with it. The Tribunal's view that there must be a "thorough" mixing before "concrete" is produced is one that is reasonably open, in the sense discussed by the Federal Court in Pozzolanic. See also Mason J in Hope v Bathurst City Council (1980) 144 CLR 1 at 7; and the observation of Kitto J in NSW Associated Blue-Metal Quarries Ltd v Federal Commissioner of Taxation (1956) 94 CLR 509 at 512.
34 It follows that the appellant's challenge to the Tribunal's finding that concrete was not produced on Portion 49b2 is a challenge to a finding of fact. Whether or not that finding of fact is correct, it was plainly one that was reasonably open. That is sufficient to exclude any attack upon it from being characterised as an appeal "on a question of law". Accordingly, ground 1 is not made out.
35 The same may be said of ground 2. As previously indicated, the Tribunal concluded that the definition of "concrete batching plant" under the Plan required the plant to have, as an integral component, an item of machinery that provided for the mixing of the ingredients as discharged through the discharge chute with added water so as to produce concrete from the one complete, if not continuous, process. The Tribunal regarded the question whether the equipment on Portion 49b2 was a concrete batching plant for the purposes of the Plan as one to be determined "on and from the facts flowing from the evidence and material" before it.
36 The appellant, however, contends that the Tribunal erred in law by requiring that any "mixing component" be permanent (ie fixed or immobile) and located on Portion 49b2, rather than recognising that part of such a plant can be mobile, and that the mixing can take place after the ingredients have been assembled.
37 In my view, the question whether the activities actually carried out on site were those of a "concrete batching plant" (as well as the related question already dealt with as to whether "concrete" was produced on site), is not a question of law, but rather a question of fact. Pozzolanic makes that tolerably clear. It was reasonably open to the Tribunal to arrive at the conclusion that without an additional fixed component, the equipment on site was not a "concrete batching plant".
38 Whether this Court would have arrived at the same conclusion, on the basis of the evidence led below, is not to the point. It can be argued that in concluding that the equipment on site did not constitute a "concrete batching plant" the Tribunal took too narrow a view of what constitutes such a plant. It is also open, however, to conclude that the Tribunal was correct in its assessment of what was necessary to constitute such a plant. The Tribunal's conclusion that there was no concrete batching plant on site because there was only occasional and sporadic mixing of water, and no equipment permanently fixed to allow all key ingredients to be thoroughly mixed, cannot be said to have been so untenable as to give rise an error of law.
39 It follows that ground 2 does not give rise to an appeal "on a question of law".
40 I next turn to grounds 3, 4 and 5 (the "existing lawful use" grounds). As previously noted the Tribunal found that batching operations (which it did not regard as "concrete batching operations") had been carried on at the site between 1997 and 1999. It based that finding largely upon a memorandum dated 30 June 1999 which was written by the appellant and addressed to the Secretary of the Norfolk Island Planning Board. The Tribunal found that the memorandum set out clearly and precisely how the appellant, as the then Building Inspector, saw the position regarding Portion 49b2 at the time.
41 The memorandum relevantly stated:
"I refer to the letter from Ray Grube addressed to The Secretary, NI Planning Board and which I was handed a copy of on Monday 28th June 1999. In this letter Mr Grube expressed concern about the apparent misuse of land zoned "rural residential", in particular Portion 49b2 Stockyard Road. I visited the site at approximately 2pm Tuesday 29th June 1999 and noted the following. Portion 49b2 has long been used as a stockpile area for raw feed material and crushed rock product for the current crushing operations on the adjoining portion 48c and as a parking area for a variety of heavy equipment. During yesterdays visit the following items of equipment were situated on this portion: 2 graders, 2 bulldozers, a low-loader, forklift, water delivery truck, bobcat, concrete mixer delivery truck, hopper and conveyor for loading aggregate, an amount of aggregate, and 2 private cars. The positioning on the site of the forklift, water delivery truck, bobcat, concrete mixer delivery truck, hopper and conveyor, and pile of aggregate suggest that the lower area of Portion 49b2 is being used as a batching area for the loading and mixing of aggregate and cement. It is my belief that this loading and mixing of aggregate and cement is entirely consistent with the present use of portion 49b2 and falls within their "existing rights". I do not believe that there has been any change of use of the land in a manner which substantially alters the scale, intensity and/or character of that present or existing use."
42 In addition, the Tribunal had before it evidence from Mr Christian to the effect that batching was already occurring on the site in 1997 when he first started work. Mr Christian said that even at that stage ready mixed concrete was being produced and sold. He said that prior to 1997 he had gone onto the site many times and seen the subject plant operating.
43 It seems that the appellant sought to resile from his 1999 memorandum, or at least qualify it. The Tribunal rejected his attempt to do so.
44 Ground 3 complains that the Tribunal erred in law in finding any concrete batching plant on portion 49b2 was an existing lawful use within the meaning of the Plan. The appellant's submissions in support of that ground complain that in arriving at that conclusion the Tribunal ignored or did not give credibility to the evidence of the Building Inspector, the Health and Building Surveyor and an adjoining land owner whose property looked directly onto Portion 49b2. They further complain that the Tribunal seemed to put the onus on the appellant and the intervenors when it stated that "[t]here was no evidence brought forward by [Mr Adams or the intervenors] firmly establishing that the subject plant did not ever operate at that site". They complain that the Tribunal did not explain how the activities of Mr Mark Robinson, a former owner of the land who had previously conducted what were arguably concrete batching operations on Portion 49b2, constituted an "existing lawful use" (emphasis added). They note that Mr Robinson was not called by Island Industries to give evidence and that there was no explanation for this. They complain that the Tribunal erred in failing to have regard to the absence of evidence from Mr Robinson.
45 Ground 3, as it was argued before me, is largely misconceived. The appellant's submissions in relation to this ground do not raise a question of law but merely attack a finding of fact. Yet there is one aspect of ground 3 as stated in the notice of appeal that may amount to a question of law, namely the Tribunal's conclusion that any past use was "lawful". However, whether or not it was appropriate for the Tribunal to treat the appellant's memorandum in 1999 as the basis for its conclusion that the earlier use was relevantly "lawful" need not be determined. Given the Tribunal's finding that the activities currently being undertaken on Portion 49b2 do not amount to the use of a "concrete batching plant", its further conclusion regarding existing lawful use is of no legal significance. Accordingly, ground 3, even if made out, does not affect the Tribunal's decision. The same may be said of ground 4.
46 Finally, ground 5 complains that the Tribunal erred in law in finding that any existing lawful use of a concrete batching plant had not been abandoned by the respondent. Each of the matters raised in support of that ground involves an attack upon the weight that the Tribunal gave to particular aspects of the evidence. In substance the ground challenges findings of fact made by the Tribunal, and does not involve any question of law. For this reason ground 5 is not made out. In any event, for the reasons set out in the preceding paragraphs that ground is of no legal significance to this appeal.
47 For the reasons outlined above, the appeal will be dismissed with costs.
I certify that the preceding forty-seven (47) numbered paragraphs are a true copy of the Reasons for Judgment herein of the Honourable Chief Justice Weinberg .
