"It is now established, as the Court said in Bolton v. Madsen
[1963] HCA 16; (1963) 110 CLR 264 , that for constitutional purposes duties
of excise are taxes directly related to goods (i.e. goods
originating in Australia), imposed at some step in their production
or distribution before they reach the hands of consumers. This does
not exclude a tax imposed, as is the duty now in question, upon the
final step in distribution, by which goods reach the hands of
consumers. The crucial question in the case of such a tax is
whether it is 'directly related to goods', in the sense in which
that and similar expressions, such as 'upon' goods, are used in the
lengthening line of judgments which have been delivered in this
Court upon the subject. What is referred to may, I think, be
described as a relation consisting in this, that some conduct is
selected by the relevant legislation as being a step in the
production, manufacture or distribution of goods and in that
character is made of the essence of the tax. A tax must
necessarily be made payable by a person; but it is not a duty of
excise unless the criterion of the person's liability is the fact
that some act of his possesses the quality of a contribution either
to the physical character of goods as subjects of commerce or to
the sequence of events which results in their being available, as
in the hands of a consumer, to be put to their ultimate purpose.
The reason is that a duty of excise is, at bottom a burden upon
home production or manufacture. Obviously it is such a burden if it
is payable upon a step in production or manufacture in its
character of such a step. Not so obviously but just as certainly,
it is such a burden if it is payable upon a step in distribution in
its character of such a step; for in that case from the time the
goods come into existence the law makes it inherent in their
nature, as goods requiring distribution in order to become
available to fulfil their purpose, that the tax shall be paid."
