The whole problem of the relation between parent and subsidiary corporations is one that is still enveloped in the mists of metaphor. Metaphors in law are to be narrowly watched, for starting as devices to liberate thought, they end often by enslaving it. We say at times that the corporate entity will be ignored when the parent corporation operates a business through a subsidiary which is characterized as an "alias" or a "dummy". All this is well enough if the picturesqueness of the epithets does not lead us to forget that the essential term to be defined is the act of operation. Dominion may be so complete, interference so obtrusive, that by the general rules of agency the parent will be a principal and the subsidiary an agent: Berkey v. Third Avenue Railway Co. [1] .
I am indebted for a knowledge of this to Paton, Jurisprudence , 3rd ed. by Professor Derham, p. 377. It is referred to in the learned commentary there on jurisprudential theories as to the nature, for the purposes of our law, of corporations as legal persons. I mention that basic question as it seems to me to be inevitably involved in a consideration of the attitude the Commissioner has taken. I do so with some diffidence but undeterred by Professor Wedderburn's acid comment on judicial disregard of academic writings and adherence in this field to outmoded theories: see Modern Law Review (1965), vol. 28, p. 70. A proprietary company may well seem to be, in reality, merely the trade-name in which a man carries on some part of his affairs. But by a following of correct legal forms the name becomes in law a thing. Formalism produces a legal substance, and its "owner" can by careful book-keeping get all the advantages, be they limited liability, relief from taxation or other benefit, which the law annexes to his sedulous use of the corporate name. A company like Casuarina may be called prestigious in the proper sense of the word, and the accountants called prestigiators. This and other metaphorical descriptions, dummy, puppet, alias, alter ego and the like come readily to mind: but they remain descriptive not definitive of legal consequences. They suggest agency or instrumentality. That, a generalized concept of agency can I think provide in some cases a practical solution of theoretical difficulties. Of course I must entertain misgivings arising from the way in which basic doctrine is expressed in Salomon's Case [1] . But the strictness of that has been giving way somewhat in recent times. I alluded to this question in my judgment in Peate v. Federal Commissioner of Taxation [1] , and I referred to it too in what I said in Gorton v. Federal Commissioner of Taxation [2] . The latter was a dissenting judgment, but my observations on this matter were merely incidental. I need not go further into the topic here. A company which speaks with the voice of the person who controls it and which acts as he directs is not necessarily to be called a facade, nor its acts in the law called shams. Its existence as a legal person is not incompatible with its practical obedience to orders: and that it acts as a taxpayer directs may be a reason for relying upon s. 260 to ignore it in some cases. But in the present case the Commissioner does not seek to disregard the existence of Casuarina. On the contrary, he seeks to tax it. He invokes s. 260 not because of any arrangement it made to enable it to avoid taxation but because it assumed the character of a public company as part of a scheme to enable Lex Sternberg Motors to avoid taxation. Casuarina is a public company within the meaning of the Act: and the Commissioner, having elected to treat it as a taxpayer, cannot I think by turning to s. 260 treat it as having a different character in law from that which it actually has. I am not concerned with what would be the position if the Commissioner had chosen an entirely different course and the liability of Lex Sternberg Motors to taxation were the question. That does not arise any more than did the position of Aquila Steel Company Pty. Ltd. in Keighery's Case [1] . The Commissioner's attempt to treat the allotment to Forum of shares in Casuarina as a "contract, agreement or arrangement" void by s. 260 fails.
