Legislative History
70 The Land and Income Tax Assessment Act 1895 imposed a land tax that was payable by every owner of land, at such rate as Parliament should from time to time declare, "in respect of all land of which he is such owner for every pound of the unimproved value thereof …" (section 10).
71 Section 68 provided:
"Improvements" includes houses and buildings, fencing, planting, excavations for holding water, wells, ring-barking, clearing from timber, or scrub, or sweet briar, or noxious weeds, or laying down in grass or pasture, and any other improvements whatsoever, the benefit of which is unexhausted at the time of valuation.
…
"Unimproved value" means, in respect to land, the capital sum for which the fee-simple estate in such land would sell, under such reasonable conditions of sale as a bona fide seller would require, assuming the actual improvements (if any) had not been made, and, in case of conditionally-purchased land, of which no grant shall have been issued, after deducting also the balances or amounts of purchase money due to the Crown in respect of the same: Provided that the unimproved value of lands reclaimed from the sea, or from any harbour or river, or made fit for building purposes by levelling or quarrying, or by the erection of retaining-walls, or by any similar operations or works, shall be the capital sum for which the said land would sell under reasonable conditions, after deducting from such sum the cost of the reclamation or making, as well as all other improvements."
72 It is to be noted that the definition of "improvements" is only an inclusive definition, and is circular because it contains the expression "and any other improvements whatsoever". It is also to be noted that it recognises that "improvement" is a concept that includes the conferring of benefit on land. It also recognises that something can cease to be an "improvement" if it ceases to confer a benefit on the land. In the two respects just mentioned, this 1895 definition accords with the construction adopted by the trial judge.
73 The broad policy that underlies this method of taxation can be seen to include the perceived inappropriateness of taxing a landholder of the value of land, to the extent to which that value has been contributed to by alterations that have been made to the land by the landholder or any of the predecessors in title of the landholder. As Knox CJ and Dixon J said in McGeoch v Federal Commissioner of Land Tax (1929) 43 CLR 277 at 290:
"In the legislation in Australia imposing tax on the unimproved value of land we think it is clear that the subject matter is sought to be taxed has always been that part of the value of the land at the relevant date which has been commonly described as the "unearned increment". The value at any given date of any given parcel of land has been considered as including two factors, namely, (1) the portion of the value at the relevant date attributable to improvements on or appertaining to the land made by the owner or his predecessors in title and (2) the portion of the value at such date attributable to extrinsic circumstances, such as public roads or railways, increased settlement in the neighbourhood, public services brought within reach and other causes not brought about by the operations on the land of successive occupiers … we think the unimproved value which is the subject of taxation under this Act is the value at the relevant date of the land in its natural state as for the time being affected by extrinsic circumstances of every kind, as, for example, those above mentioned, but not by what has been done to it or upon it in the shape of the improvement of any kind effected by the operations of successive owners the benefit of which continues as a factor in the then present value of the land."
74 Any such broad policy can only be worked out in detail by reference to the particular words of the statute, and the course of judicial interpretation of the statute; that is what has happened over the years since 1895. One factor that is relevant in the present case is that Knox CJ and Dixon J recognised that "improvement" is necessarily a comparative notion, and held that the state of affairs by reference to which the legislative policy decided whether something was an "improvement" was "the land in its natural state as for the time being affected by extrinsic circumstances of every kind". That is consistent with the construction that the trial judge has adopted in the present case.
75 When the Valuation of Land Act 1916 was originally enacted, section 6 provided:
"The unimproved value of land is the capital sum which the fee-simple of the land might be expected to realise if offered for sale on such reasonable terms and conditions as a bona-fide seller would require, assuming that the improvements, if any, thereon or appertaining thereto, and made or acquired by the owner or his predecessor in title had not been made."
76 The Act contained no definition of "Improvements". Between 1916 and 1961 there continued to be no definition of any species of "improvements" in the Act.
77 Section 15 contained a provision requiring the Valuer-General before making valuation in any district to send to every land owner in the district forms containing "such questions as may be prescribed relating to … the nature of improvements thereon". Section 15(3), then, as now, made it a criminal offence for an owner to not return the form in time, or to make any false statement knowing it to be false in any material particular. Thus, from its beginning, the Act has given rise to the unlikelihood of the legislature intending every landowner to be in a position to make the fairly complex judgment that is involved in deciding whether a particular alteration of the state of land is one that is beneficial to the highest and best use of that land.
78 The Valuation of Land and Local Government (Amendment) Act 1959 introduced a new section 6(2), in the same terms as the present section 6A(2).
79 At the time of introduction of the bill that became the 1959 amending Act, the Minister for Local Government and Minister for Highways, Mr Hills, explained its purpose as being:
"… to remove an anomaly relating to unimproved valuations that has been disclosed by a recent decision of the Land and Valuation Court. In that case, which related to an area of land used for industrial purposes in a living area zone under the County of Cumberland planning scheme, the court held that the unimproved value of the land must be assessed on the basis of its zoning, notwithstanding that the planning scheme gives complete protection to the continued use for industrial purposes of the land and the buildings thereon. The result of this decision is that considerably lower unimproved values must be fixed than at present in respect of all lands occupied by industrial and commercial buildings in living areas or in proclaimed residential districts. It follows that the court's decision will have a disastrous effect upon the determination of the unimproved values of land occupied by service stations, industrial buildings and commercial premises in living areas, and of land occupied by some classes of residential flat buildings. As a result, a very substantial body of ratepayers will be relieved of a great proportion of the rates that they should justly bear, and the burden thereof will necessarily be transferred to the other owners of property, namely, home owners."
80 Mr Hills quoted the following from "a recent decision of the Privy Council":
"… the physical improvements, with any value which they may attach to the land on which they are situated, (must) be excluded from the valuer's computation. The land will then be valued as land void of buildings but situated in the community with the amenities and facilities which have grown up around it …"
