The meaning of the expression "duties of excise" as found in the Constitution has received a great deal of consideration during the lifetime of the Court. On the one hand the Court has taken a limited view by confining duties of excise relevantly to duties upon the manufacture or production of goods On the other hand, the Court has not taken the narrow view that to be a duty of excise the tax must be laid directly on the act or process of manufacture or production. In my view, it should be regarded now as acceptable and settled doctrine that the tax will be a duty of excise if it is upon or in respect of goods at any point including the point of manufacture or production, as they pass to consumption. This view, if I may respectfully say so, has been rightly taken, for a tax upon goods at any stage of their distribution will, in general, and sooner or later, according to circumstances, bear on the rate or level at which they are manufactured or produced or if not locally produced, on the extent of their importation. But there is no warrant, in my opinion, to require it to be established in any particular case that the tax in question will in fact so bear on manufacture or production. Its relevant effect will be presumed: it is enough that the impost is upon or in respect of goods before they have actually reached the consumer. But, of course, the demonstration of the effect of the tax upon such manufacture or production may assist an affirmative conclusion to the question whether the tax is a duty of excise.
As Barwick C.J. had pointed out in Anderson's Pty. Ltd. v. Victoria [52] , "in arriving at the conclusion that the tax is a tax upon" a relevant step in the process of production, manufacture or distribution, "consideration of many factors is necessary, factors which may not be present in every case and which may have different weight or emphasis in different cases". His Honour continued [53] :
The "indirectness" of the tax, its immediate entry into the cost of the goods, the proximity of the transaction it taxes to the manufacture or production or movement of the goods into consumption, the form and content of the legislation imposing the tax - all these are included in the relevant considerations. But in the end what must be decided is that the tax is in substance a tax upon the relevant step. That being the central question in a controversy as to the nature of the tax, it will not, in my opinion, necessarily be resolved by the form of the tax or by identifying what according to that form the legislature has made the criterion of its imposition, however important in any particular case those matters may be.
Prominent among factors which can be added to those mentioned by Barwick C.J. is whether the amount of the tax bears a discernable relationship to the quantity or value of the goods manufactured or produced. While each of the above factors is relevant, no one of them is, by either presence or absence, necessarily conclusive of the ultimate question whether the tax is in substance a tax on the manufacture or production of goods.
