But in any event, the argument advanced in support of the submission that the regulations were void as not affording just terms of acquisition is completely lacking in substance. Before Fullagar J., a great deal of evidence, oral and documentary, was adduced to show that the price realized by the Australian Government for the wool acquired under the regulations gave the growers as favourable a return for their wool as could reasonably have been obtained, and that the manner in which the appraisement system operated to distribute the flat rate price amongst the wool growers in accordance with relative values as expertly determined on the basis of a table of limits accurately prepared by persons of great knowledge and experience, was as fair as any that could have been devised. But we do not need to review this evidence in any detail, or to add to the comments which Fullagar J. has made upon it; for, with the whole history of the matter laid open for examination, and with every possible ground of criticism of the regulations available to be relied upon, in the end the attack has been pressed at one point only. It commences with the statement, indeed the admission as the argument regards it, which is contained in reg. 2, that the purpose of the regulations was to provide for the carrying out of the Arrangement made between the Government of Great Britain and the Government of the Commonwealth for acquiring, in connection with the war, all wool produced in Australia, with certain exceptions. Thus, it was said, the acquisition of wool was provided for by the regulations for the sole purpose of servicing the Wool Purchase Arrangement. The ultimate objective was recognized as being the successful prosecution of the war, but the method adopted, counsel insisted, was neither more nor less than the compulsory acquisition of wool for the purpose of reselling it to the United Kingdom Government under the Arrangement, subject to the exception of so much as might be required for local manufacture. The Arrangement entitled the Australian Government to receive a flat rate price, a payment to cover handling charges, and one-half of any profit which should result to the United Kingdom Government from the sale to other countries of any of the wool not required for Britain's own needs. Thus, in relation to all the wool acquired except such of it as was needed for local manufacture, the acquisition by the Commonwealth was for the sole purpose of getting in exchange for it, without incurring any risk of loss, a net sum consisting of the flat rate price plus the one-half share of profits resulting from disposals by the United Kingdom. For such an acquisition, it was contended, terms could not be just which failed to entitle the dispossessed owners, as of right, to have divided amongst them or applied for their benefit, if not in ratable proportion to the appraised values of their respective parcels of wool, at least in some reasonable manner, whatever moneys the Commonwealth might actually receive in respect of its half share of the United Kingdom's profit on external sales. And the final step in the argument was to point to reg. 30 (2) and adopt the statement of the effect of the regulations which appears in the Court's judgment in Ritchie v. Trustees Executors & Agency Co. Ltd. [1] : "No payment to the supplier of wool, beyond, at all events, appraised value (whether appraised value simpliciter or adjusted to flat rate is not material) was required by the regulations; all else remained a matter of administration" [2] . Thus, it was said, the suppliers of the wool were given no right to participate in the profit, and that circumstance suffices to make the terms of acquisition unjust. The mere chance of participation in consequence of an administrative decision given in exercise of a discretion does not make them just.
