"36. It might also be noted at this point that the applicable legislation imposes a tax. The courts now approach such legislation as being directed to the substance as well as to the form of transactions. To the extent that cases, formerly of high authority, such as Partington v. Attorney-General[3] and Inland Revenue Commissioners v. Duke of Westminster[4] stand in the way of this approach, they are no longer to be followed: Hepples v. Federal Commissioner of Taxation[5]. It nevertheless remains true that the intention to impose a tax or duty must be shown by clear and unambiguous language and cannot be inferred from ambiguous words: Brunton v. Commissioner of Stamp Duties[6]. It is also generally true that, where a taxing Act provides for an exception to the imposition of a charge, and where the construction of the exempting words is 'seriously in doubt, the interpretation should favour those whose claims are based upon the exceptions': Burt v. The Commissioner of Taxation[7]. 37. There is in my opinion every reason to suppose that Parliament intended to combine, with the value of the real property, the value of all other property included (to use the words of the Explanatory Memorandum) 'as an integral part of [the] sale.' The word 'chattels' was adopted not because Parliament wished to restrict the property caught by the amendment to moveable articles such as household furniture but because 'chattels' is the word which naturally comes to mind when one is considering the nature of the personal property that is most commonly included in and with the sale and purchase of land. But there is no sensible reason why Parliament would want to include for the purpose of assessment some categories of personal property, while excluding others, where in all cases the property in question was 'sold as an integral part of [the] sale'. Certainly, the mere adoption in s.63 of a word of such uncertain meaning as 'chattels' gives no clear indication of the location of any line which might be drawn between some categories of personal property which, being 'an integral part of [the] sale', should be assessed and other categories of personal property, although being equally integral, should not. 38. On the contrary, s. 63 (3) speaks of 'chattels ... that by reason of the sale of ... real property ... are sold ... to the transferee'. The licences transferred by Mr. Elliott to the appellant were without a shadow of a doubt sold by reason of the sale of 'Madowla Park'. The word 'chattels' is capable of encompassing those licences. The fact that another word or expression might be more apt is in the circumstances no answer. This, I think, is particularly so given the then Treasurer's use of the expression 'personal property' in the relevant passage in his budget speech. 39. Licences which confer rights to irrigate specified parcels of land, or to draw water for domestic and stock purposes being conducted on that land, have a direct an immediate impact on its value. When sold with the land they are necessarily as integral a part of the sale as anything could be which is not the land itself. I repeat: to exclude such property from the scope of s. 63 (3) merely because the word chosen to there describe it, while accurate in itself, is not as apt as another descriptive word or phase, would I think fly in the face of the will of Parliament. 40. The appellant submits that there is a relevant distinction between chattels which on the one hand are tangible and moveable and those which are on the other intangible and cannot be moved - at least not by the means in transporting physical objects. This distinction is, the appellant submits, given substance by the reference in s.63(3) to 'chattels not being stock in trade held or used in connection with a business carried on or in connection with the real property'. The words 'held or used in connection with a business carried on or in connection with the real property', it is submitted, qualify not the expression 'stock in trade' but the word 'chattels'. But 'chattels not being stock in trade held or used in connection with a business carried on or in connection with the real property' are (the submission continues) necessarily physical objects. It must follow that intangible property such as water rights, if they constitute property at all (which, of course, the appellant submits they do not) are excluded from the operation of s.63(3) and, necessarily therefore, of s.63(4). 41. There are, it seems to me, two problems with this submission. First, if the water rights enjoyed by the appellant constitute chattels, then it could sensibly be said that they are chattels used in connection with the business of growing rice. Secondly, the expression 'not being stock in trade held or used in connection with a business carried on or in connection with the real property' is not divided by punctuation from the word 'chattels'; and it was inserted into the sub-section, as a single expression, by the Stamps Act 1984. Accordingly, it is surely more appropriate to link 'stock in trade' rather than 'chattels' to that which is 'held or used in connection with a business carried on or in connection with the real property'. 42. The form presently taken by sub-section (3) indicates to my mind an intention by Parliament to exclude from duty those objects known as stock in trade which, if they in reality form part of one transaction of which the sale of real property is another constituent part, do so not so much because they are sold as a package with the land but because they are sold as part of a business which is sold as a package with the land. 43. In this respect, they are analogous to the stock and implements sold in connection with a conveyance of land used for primary production. They are not connected with the land as are free-standing cupboards or wardrobes or soft furnishings or furniture. Their first connection is with a business - which (ex hypothesi) happens to be carried on or in connection with the land. Their exclusion from the assessment of stamp duty is explicable and logical on that basis. 44. Not so the rights attached to water licences. They are so intimately connected with the land that they directly affect the use to which it can be put and the profits which may be realised from that use. There is no logical reason why land to which rights of irrigation and the like are linked, and the value of which is increased thereby, should be taxed on a basis which differs favourably from that which applies to land with no better access to water than the rain which falls directly onto the land from the heavens. In other words, there is no reason why the farmer in a region of high and dependable rainfall should pay more duty than a farmer in a drought-prone region but who has access to a comparable supply of water (access to which is regulated by the Crown in the general public interest) from which his property may be successfully irrigated. 45. In my opinion, the Parliament intended to include in the calculation of stamp duty payable on instruments of transfer of land used for primary production not only household chattels such as detached wardrobes or unfixed floor coverings but also such intangible assets as water rights. Each, if part of the sale of the land, are an integral part of that sale - the water rights above all. None fall into the same category as stock or implements. The latter, like stock in trade, are sold as part of the business with which the land is associated. The former (that is, household chattels and water rights) are sold either for domestic use or as a constituent element in the land itself. It is true that water rights may well be vital to the use of real property for primary production; but they are vital in the way the land itself is vital. In this respect, their role in the scheme of things can I think be sensibly differentiated from that of stock or implements; and the reasons which prompted Parliament to exempt the latter from duty do not apply to the former. Indeed, water rights are such an integral part of a transaction involving properties used for primary production that Parliament may have thought it entirely appropriate that their value be included in any assessment of stamp duty. The use of the words 'stock, implements or other chattels' in s.63(4) is compatible with this assessment of Parliament's intention."
