he could not in any form of action recover the price; and it would be singular if the same act which saved the vendee the price of the sheep should vest in him a right of action for their full value without deducting the price.
The whole point of the case lay in the interest which the seller had in the goods by reason of being still in possession of them at the time he converted them - that is to say his interest as an unpaid seller, which had necessarily to be allowed for in valuing the loss by the buyer of his interest in the same goods: see the important discussion of this case in Attack v. Bramwell [5] . Gillard v. Brittan [2] provides a clear contrast, for the seller in that case had delivered the goods to the buyer and the conversion was by way of a retaking, so that the interest the buyer lost by the conversion extended to the whole right of possession of the goods untrammelled by his liability to pay the price. The decision was that for that reason his damages could not be reduced on the ground that the price was unpaid. There is no inconsistency between the two decisions, and the present case is covered precisely by Gillard v. Brittan [2] , which no one but Denman J. seems ever to have doubted and textwriters have generally approved: see Bullen & Leake, Precedents of Pleadings, 3rd ed. (1868), p. 242; Benjamin on Sale, 8th ed. (1950), p. 949; Mayne and McGregor on Damages, 12th ed. (1961), p. 609, par. 704, note (30); Halsbury's Laws of England, 3rd ed., vol. 38, p. 796, par. 1323, note (s). The Court which decided Gillard v. Brittan [2] was a strong one. Lord Abinger C.B. pointed out that the opposite view would allow a party to set off "a debt due in one case against damages in another" - which is precisely what the defendant in the present case seeks to do; and one may add that the departure from principle that would have been involved in so doing is underlined by Baron Parke's acknowledgment in Mondel v. Steel [1] , that the converse process, of setting off damages for a breach of warranty against the price payable, though allowed for convenience, was in truth a deviation from principle. Lord Abinger added an observation [2] which is much in point in the present case: "The verdict in this case does not at all affect the right of the defendant to recover the whole" (of the price) "due to him from the plaintiff." Baron Alderson emphasized the essential disconnexion between the cause of action for the retaking of the goods and the cause of action for the price by saying that while the jury might consider the whole of the circumstances really belonging to "the case", i.e., the action for taking of the goods, a direction which the trial judge had given that the circumstances included the plaintiff's debt to the defendant was a direction to consider "a circumstance which ought to be excluded"; "otherwise", he said, "it is equivalent to adding a set-off in trespass". Baron Gurney concurred. Baron Rolfe said that no authority had been cited which supported the contention that a party who wrongfully retakes possession of his own goods (i.e., which he has sold) thereby debars himself from suing for the price. He found it unnecessary to give any opinion on the point; but the absence of authority upon which he remarked has continued, so far as I can find, to the present day. The truth, as it seems to me, is that the rule of practice now contained in s. 54 (1), enabling a buyer, if he so chooses, to have his claim against the seller for breach of warranty treated as if it were a subject of set off though in principle it is a subject for a separate action (a cross action), provides no logical or legal justification for the proposition that the seller may require his claim against the buyer for unpaid purchase-money to be treated, over the objection of the buyer, as if it had been satisfied by being set off against his liability for breach of warranty.
