When the commissioner came to make the assessment of the value for estate duty of the deceased's estate, he added £20,000 to the value of the deceased's interest in Maples. He ascribed the addition to the "proportion of goodwill" in the partnership business. There stood in his favour the decision of the majority of this Court (Rich, Starke and Williams JJ., Latham C.J. and McTiernan J. dissenting) in Trustees Executors & Agency Co. Ltd. v. Federal Commissioner of Taxation (Milne's Case) [1] . That case differed materially from the present only in the fact that under the deed to which Milne was a party no allowance in respect of the value of the goodwill of the partnership business was to be made to a partner or his representatives on his death, retirement or expulsion. All five members of the Court had decided that no share in the goodwill devolved upon the executor or formed part of the deceased's personal property so as to be comprised in his estate under s. 8 (3). But the majority held that the interest in goodwill was caught by s. 8 (4) (e) as a beneficial interest of the deceased at death which by virtue of an agreement made by him passed or accrued on or after his decease to other persons, namely the surviving partners. The minority dissented on the ground that there was no "passing or accruing" of the deceased's interest as such to the surviving partners. There was simply a cesser of his interest with a consequential enlargement of theirs. Latham C.J. relied upon Attorney-General v. Boden [1] , where Hamilton J. held that there was no "passing" of the goodwill to the surviving partners under a partnership deed in even stronger terms. In that deed there was no option; it was an absolute provision that on the partner's death or on his otherwise ceasing to be a partner that particular partner's share should accrue to the two surviving or continuing partners subject only to payment of the value ascertained by an account without valuation or allowance for goodwill, which should accrue to the two survivors in equal shares. Faced with this decision in Milne's Case [2] the executors of Thomas determined to challenge it in the Privy Council. As a first step they appealed to this Court where they confessed that they could not succeed unless we would allow the correctness of the decision in Milne's Case [2] to be reconsidered; and that we refused to do: Perpetual Executors & Trustees Association of Australia Ltd. v. Federal Commissioner of Taxation (Thomas' Case) [3] . The executors obtained special leave to appeal from the inevitable order upholding the commissioner's assessment. In deciding this appeal the Privy Council adopted a view of s. 8 of the Estate Duty Assessment Act and of the situation produced by the deeds in this and in Milne's Case [2] which struck at the foundation of alike the view of the majority and the view of the minority in Milne's Case [2] . Their Lordships construed sub-ss. (3) and (4) of s. 8 as two mutually exclusive provisions. If a case fell within sub-s. (3) it must be excluded from the application of sub-s. (4). The source of this interpretation is doubtless to be found in Earl Cowley v. Inland Revenue Commissioners [4] ; cf. Attorney-General v. Milne [5] and In re Duke of Norfolk: Public Trustee v. Inland Revenue Commissioners [6] though of course the statutory provisions are very different. As to the devolution of the deceased's interest in goodwill, their Lordships drew no distinction between the effect of the provisions of the partnership instruments in Boden's Case [1] in Milne's Case [2] and in the present case. In all three cases, as their Lordships held, the entire interest of the deceased partner in the assets of the partnership including goodwill vested in the executors on his death. On this footing, as is obvious, sub-s. (3) of s. 8 applied in the two Australian cases and, as the sub-sections are to be regarded as mutually exclusive, sub-s. (4) became inapplicable. As to Milne's Case [2] , Lord Cohen, speaking for the Board said this: - "In their Lordships' opinion the interest of Milne in all the partnership assets, including goodwill, vested in his executors on his death, although his executors would be bound, if the option were exercised, to transfer that interest to the purchaser at the price fixed in accordance with the partnership deed" [3] . Referring to the decision of Hamilton J. in Boden's Case [4] that the interest of the deceased in goodwill was not property which "passed" on his death (scil to the surviving partners) within the meaning of s. 1 of the Finance Act 1894 but that the goodwill was property in which the deceased had an interest ceasing on the death of the deceased, Lord Cohen said: "Their Lordships are unable to agree with this view. In their opinion the deceased partner's interest in goodwill in such a case must pass with his interest in the other assets to his legal personal representative, and the fact that its value is not to be taken into account in calculating the price receivable by the estate for his interest in the partnership is irrelevant" [5] . (Irrelevant means of course irrelevant to liability to duty, not to valuation.) The present case is a fortiori. For whatever view might be taken of the effect of the provisions of the respective deeds in Boden's Case [1] and in Milne's Case [2] the deed in the present case contemplates an interval between death and the exercise of the options and immediately on death the entire interest of the deceased in the partnership assets including goodwill must devolve upon the executor of the deceased partner pending the election to exercise or not to exercise the options.
