The result, so far, has been to show not merely that the beneficiaries in one year's income are unascertained as to the next year's income, but also that they are not necessarily the same persons who will be beneficiaries as to the corpus. Children yet unborn, may come in, and may be the only beneficiaries as to the corpus. Not only is the class not ascertained, but not even are the maximum members of the class at present ascertained or ascertainable. On what principle, then, can it be said that the present beneficiaries for the relevant annual period of "net income," can be said to be "entitled" to the corpus under the second trust? With the greatest respect to the opposite opinion, I find standing in my way and preventing its acceptance some of the most vital and fundamental principles of equity. The only doctrine of Finch's Case[29], that an equitable right was merely a chose in action, is, of course, not the law now. Equity regards the cestui que trust of property as the true owner of the property itself. But it is, nevertheless, true that equity acts only in personam, and the rights it recognizes and enforces are rights in personam and not rights in rem. See Butler's note iii. to Coke upon Littleton, 290b. In Ewing v. Orr Ewing[30] Lord Selborne L.C. said: "The Courts of equity in England are, and always have been, Courts of conscience, operating in personam and not in rem; and in the exercise of this personal jurisdiction they have always been accustomed to compel the performance of contracts and trusts as to subjects which were not either locally or ratione domicilii within their jurisdiction." That statement in 1883 is, in effect, what was said in Burgess v. Wheate[31] in 1759. Lord Mansfield then said[32]: "A trust in Chancery is the estate at law." Lord Keeper Henley said[33]: "Where there is a trust, it should be considered in this Court as the real estate, between the cestuy que trust and the trustee, and all claiming by or under them." See also the speech of Lord Selborne in Hansard (N.S.), vol. ccxiv., p. 333, quoted in Underhill on Trusts, 7th ed., at p. 6. Further, "the nature and extent of the equitable interest must be determined by the words by which it is created" (per Lord Davey in Earl of Mountcashell v. More-Smyth[34]). It is an inevitable consequence of what is there said that, before you can assert that any person has an equitable interest, you must ascertain the trust by which he gets it. His equitable interest is commensurate only with the relief which equity will give him. In Central Trust and Safe Deposit Co. v. Snider[35] Lord Parker, for the Judicial Committee, illustrated this principle in a case relating to specific performance. At page 272, a page deserving of careful reading, the learned Lord said: "Though the purchaser of real estate might before conveyance have an equitable interest capable of registration, such interest was in every case commensurate only with what would be decreed to him by a Court of equity in specifically performing the contract, and could only be defined by reference to the relief which the Court would give by way of specific performance." The same view was held and applied by the Privy Council in Plimmer v. Wellington Corporation[36], where a passage from the judgment of Lord Kingsdown in Ramsden v. Dyson[37] was cited, a passage based on the principle that equitable property is commensurate with equitable relief. Precisely the same measure is applicable to trusts. In Hawkins v. Chappel[38] Lord Hardwicke said: "Whoever has the trust is in this Court considered as having the beneficial interest, and therefore the ownership of the estate." It was there argued that by the words of the will the interest of the testator's daughters was contingent, but the Lord Chancellor answered that by saying: "It is objected too, that this interest of the daughters is a contingency, and to arise in futuro; but I am clear of opinion, it is a vested interest." It is manifest that if the Lord Chancellor had considered the daughters' interest contingent, he would not have held them to be the beneficial owners of the property, because they would not have had "the trust," but others would have shared it with them. In other words, he looked to see what was "the trust." The late Professor Maitland in his Equity, at p. 121, quotes with approval Pollock on Contracts, 7th ed., at p. 209, as stating the true way to understand the nature and incidents of equitable ownership. It exactly squares with what has been already stated, and is borne out consistently by the way in which Courts of equity deal with trusts. It is, as I understand, a fundamental principle of equity in relation to trusts that, whatever the trust may be, that and that only can be enforced by the Court, subject only to a special rule of equity, sometimes called "the rule in Saunders v. Vautier"[39]. The main principle is that the Court's "business" is to execute trusts, not to alter them (see per Farwell L.J. in In re Hazeldine's Trusts[40]). In Letterstedt v. Broers[41] the Privy Council, speaking by Lord Blackburn, said, with regard to a trust, that the principal duty of a Court of equity is "to see that the trusts are properly executed." In Leake on Property in Land, 2nd ed., at p. 98, the maxim is quoted as "The equity is the land." In Lewin on Trusts, 12th ed., at pp. 884 et seqq., the cestui que trust's estate in a special trust is said to be "the right to enforce in equity the specific execution of the settlor's intention, to the extent of that cestui que trust's particular interest." Even a contingent legatee, as being what the learned author calls "a quasi cestui que trust," has certain rights. If he can show at the time he brings his suit that he is a person who either by name or designation is an ascertained person having an interest in the execution of the trusts, he is a competent party to ask the Court's assistance. Therein lies the distinction between law and equity. At law, the contingent devisee has no interest in the land. In equity, an identifiable contingent cestui que trust has an interest beyond a mere possibility in the execution of the trusts, and in that sense he has, in the eye of a Court of equity, an interest in the trust estate, because, as shown, in equity the trust is everything. But his interest in the trust estate at any given moment is measured by the relief which equity is then prepared to give him, that is, by the rights which the due execution of the trusts as framed by the creator of the trusts will at that moment give him. There is, however, the special rule above mentioned, which, if not properly understood, may lead to difficulty. In Harbin v. Masterman[42] Lindley L.J. says: - "Notwithstanding the general principle that a donee or legatee can only take what is given him on the terms on which it is given, yet by our law there is a remarkable exception to this general principle. Conditions which are repugnant to the estate to which they are annexed are absolutely void, and may consequently be disregarded. This doctrine, I apprehend, underlies the rule laid down in Saunders v. Vautier24 Beav., 115; Cr. & Ph., 240., and enunciated with great clearness by Vice-Chancellor Wood in Gosling v. Gosling3John., 265, at p. 272.." I believe it has been reserved for that eminent jurist Lord Lindley to state so clearly the true principle involved in the exception. That statement of the fundamental doctrine, however, not only makes all the relevant decisions harmonious, but brings equity into line with legal doctrines on the same subject. The House of Lords, on the appeal (Wharton v. Masterman[45]), appears to have tacitly adopted that point of view. Two lines of the judgment of Lord Davey[46] may be referred to as here important, viz.: "There is no condition precedent to happen or to be performed in order to perfect the title of the legatees" In the present case, as I have said, there is an essential condition precedent even to the ascertainment of the legatees. In Lewin on Trusts, 12th ed., at p. 884, this subject is dealt with as the conversion of a special trust into a simple trust. It is there stated: "If there be only one cestui que trust, or there be several cestuis que trust, and all of one mind (in each case sui juris), the specific execution may be stayed, and the special trust will then acquire the character of a simple trust." In that case, and only in that case, the cestuis que trust are "the absolute beneficial proprietors." Two things, however, are essential. The first is that the election to put an end to the specific trusts must be by persons who are absolutely interested in the property in question, and, if they have only limited or defeasible interests, their direction is ineffective, and consequently they are not in equity regarded as the full owners of the property. The authority for this is abundant, and includes the following cases: Sisson v. Giles[47]; Harcourt v. Seymour[48]; Cookson v. Cookson[49] and In re Douglas and Powell's Contract[50]. Applying the principle stated by Lord Lindley, there is, in the case of beneficiaries not absolutely entitled, no repugnancy between giving them to the full all the full interest they are then entitled to, and not putting them into uncontrolled enjoyment of the trust estate. If they are presently absolutely entitled, however, as were the daughters in Pearson v. Lane[51] or the taxpayers in Archer's Case[52], they can elect to keep unsold the property, instead of having it sold according to the specific terms of the trust. That was the point of learned counsel's argument in Archer's Case given effect to by the Court. Selling the property against the will of the beneficiaries in such a case is, in the view of equity, a fetter on the uncontrolled enjoyment of the property, which the beneficiaries in question alone are to share in. In that case Grant M.R; was very distinct in Pearson v. Lane[53] in stating the rule that equity must first ascertain "the objects of the trust." He was also careful to point out[54] that their right depended on "the event, that has happened, viz., their father's death without issue male." Had the question arisen before that contingency had happened, it is manifest from the whole tenor of the judgment that the Court would have held that no title could have been made. So in the example given by Lord Cairns in Brook v. Badley[55], the four persons are persons absolutely and not contingently entitled. The last-mentioned case rests on the circumstance that, on the construction of the Mortmain Act, a devise is within the Act as an interest in land even though it is only necessary to deal with an interest in land to give effect to it. See per Brett M.R. (then Brett L.J.) in Ashworth v. Munn[56], per Cotton L.J. in In re Watts; Cornford v. Elliott[57], and per Swinfen-Eady L.J. in Gresham Life Assurance Society v. Crowther[58]. Personally I cannot think Lord Cairns would ever have sanctioned the notion that equity regards persons as the beneficial owners where, as here, (1) they are only contingently entitled; (2) they are not yet ascertained as the objects of the trust; and (3) other persons yet unborn may become entitled at the date of distribution. No doubt a man only contingently entitled may, in addition to statutory powers, elect beforehand, so as to bind himself - should he ever become absolutely entitled - or he may assign so as to similarly bind himself in that event; but the point is that until he does become absolutely entitled he is not either in law or in equity the owner of the property. The election or assignment is sustained in equity as election or a contract binding on his conscience when, as Lord Macnaghten in Tailby v. Official Receiver[59] phrased it, "the subject matter ... comes into existence." (See In re Dallas[60].) But how can the present beneficiaries, on these principles, escape from the specific trust for conversion? The trust is imperative, and the objects of the trust, whoever they may turn out to be, if any, are to take the proceeds as personalty and not as realty (Fletcher v. Ashburner[61] and Halsbury's Laws of England, vol. xiii., pp. 106-107). The objects of the trust may - if sui juris - then, at the time when they are ascertainable, elect to reconvert, and in that case they will be entitled to the property in its actual state. The rule in such case is thus stated by Pearson J. in In re Lewis; Foxwell v. Lewis[62]: "Whenever real estate has been converted into personalty, or, according to the doctrine of a Court of equity, is to be treated as having been converted into personalty, it must then descend as personalty, unless some person who is absolutely entitled to it has shown in some way that he has elected to take it as real estate."
