This reasoning assumes, as I understand it, that if the transaction under consideration is genuinely regarded by the parties as a sound commercial transaction negotiated at arm’s length and capable of justification on purely commercial grounds, it cannot offend against s.54 [Companies Act 1948]. This is, I think, a broader proposition than the proposition which the judge treated as having been accepted by counsel for Belmont. If A Ltd buys from B a chattel or a commodity, like a ship or merchandise, which A Ltd genuinely wants to acquire for its own purposes, and does so having no other purpose in view, the fact that B thereafter employs the proceeds of the sale in buying shares in A Ltd should not, I would suppose, be held to offend against the section; but the position may be different if A Ltd makes the purchase in order to put B in funds to buy shares in A Ltd. If A Ltd buys something from B without regard to its own commercial interests, the sole purpose of the transaction being to put B in funds to acquire shares in A Ltd, this would, in my opinion, clearly contravene the section, even if the price paid was a fair price for what is bought, and a fortiori that would be so if the sale to A Ltd was at an inflated price. The sole purpose would be to enable (ie to assist) B to pay for the shares. If A Ltd buys something from B at a fair price, which A Ltd could readily realise on a resale if it wished to do so, but the purpose, or one of the purposes, of the transaction is to put B in funds to acquire shares of A Ltd, the fact that the price was fair might not, I think, prevent the transaction from contravening the section, if it would otherwise do so, though A Ltd could very probably recover no damages in civil proceedings, for it would have suffered no damage. If the transaction is of a kind which A Ltd could in its own commercial interests legitimately enter into, and the transaction is genuinely entered into by A Ltd in its own commercial interests and not merely as a means of assisting B financially to buy shares of A Ltd, the circumstance that A Ltd enters into the transaction with B, partly with the object of putting B in funds to acquire its own shares or with the knowledge of B’s intended use of the proceeds of sale, might, I think, involve no contravention of the section, but I do not wish to express a concluded opinion on that point.
