The judgment and reasons of the Full Court, delivered by Mansfield S.P.J., are, in my opinion, right. His Honour stated the question at issue and reasons for answering it adversely to the present appellants in a passage with which I entirely agree, and upon which I could not improve. It is as follows: "The whole question in issue in this case depends upon the terms of s. 4 of The Succession and Probate Duties Act 1892. The word "property" as used in that section covers every form of right or benefit, and the matter therefore depends entirely on (a) the meaning of the words "upon the death of any person", and (b) the substantial effect of the will in relation to circumstances in which it operated (cf. Commissioner of Stamp Duties (Q.) v. Donaldson [1] , per Isaacs J.). To come within s. 4 so as to be conferred as a succession the property must "by reason of" the disposition - that is, by reason of the terms of the will relevant to that property - have passed to another at the given moment, namely, upon the death of the testator (ibid.). The date of the entitlement is the date of death, and if the circumstances of the case reveal that after date of death of the person alleged to be the successor, some other person is by reason of a disposition shown to be entitled to a benefit which can be classed as property within the meaning of the Act, and to which he was not entitled before that death, then a "succession" will take place and it will be liable to succession duty under the section. If the entitlement takes place after an interval or is subject to a contingency the duty is payable on the expiration of that interval or upon the happening of the contingency, as the case may be. In the instant case, the beneficiaries, by reason of the will of the testator and upon his death became beneficially entitled to certain rights. The testator as a shareholder in the company held a controlling interest therein which passed to his trustees upon his death. The trustees were bound to act in accordance with the testator's directions, and because of the control which they then possessed they were able to alter the articles of the company and acquire the lands specified by the testator and hold them on the trusts directed by him. The interest in the lands which the appellants Frank Victor Sharpe and Alfred Roy Sharpe received was the fruit of the testator's interest in the company and the directions contained in his will. The important point is that the exercise of the trustees' power and the performance of their fiduciary obligation must, so to speak, be read into the will, so that the benefit which the beneficiaries obtained must be considered to pass under the will (cf. Queensland Trustees Ltd. v. Commissioner of Stamp Duties [2] ). There is in my opinion no new and independent title which precluded the operation of the provisions of the will, and there was therefore a succession. As the contingency to which the acquiring of an absolute interest was subject, has now happened, the succession duty thereon is payable." It was argued for the appellants that all parties are estopped in relation to the question by way of issue-estoppel. This argument is based upon the judgment in the case of In re Sharpe; Queensland Trustees Ltd. v. Commissioner of Stamp Duties [1] . In that case the Supreme Court of Queensland decided that the "nomination of trustees" and the "schedule of trusts" constituted a settlement within the meaning of s. 2 of The Stamps Acts 1894 to 1940 and as such were liable to ad valorem duty. The majority of the court (Philp and Mansfield JJ.) applied Davidson v. Chirnside [2] . Actually, they decided the case without reference to the will of the testator. "The instrument must be assessed by what appears on its face, and on its face it sufficiently appears to be a settlement of the lands described therein without reference to the will" per Philp J. [3] "By s. 4 a tax is imposed upon instruments - not upon transactions - and, as Higgins J. said in Davidson v. Chirnside [4] , "the more instruments you want, the more stamps you must buy." By s. 2 the term "instrument" means and includes any written or printed document."
