"He cannot leave it to another person to make such a disposition for him" (i.e. a complete disposition of the beneficial interest) "unless he has passed the beneficial interest to that person to dispose of as his own. He may, indeed, provide that a special class of persons or of institutions invested by law with the capacity of persons to hold property are to take in such shares as a third person may determine, but that is only because he has disposed of the beneficial interest in favour of that class as his beneficiaries."
This view, the question of charity apart, would confine the creation of powers of appointment which could be regarded as testamentary dispositions to powers in the nature of a trust and to powers to appoint amongst a class, where it could be concluded from the terms of the will that the class obtained by the will a beneficial interest in the property the subject of the power. If this were the exclusive explanation of the validity of a power of appointment created by will, a power to appoint amongst a class with a gift over in default of appointment would seem to be excluded because the presence of the gift over denies the existence of a beneficial interest in the class. It may be that Sargant J. took this limited view of the creation of a power of appointment as a relevant disposition when he expressed the exceptions to the general rule that the testator must himself make his testamentary dispositions. In Re Hughes; Hughes v. Footner [3] his Lordship said:
The general law on the subject is well settled, and is that the power of testamentary disposition is essentially a personal one and cannot be exercised by a will merely purporting to delegate to another the distribution of the testator's estate and the ascertainment of the objects of his bounty. But there are some real or apparent exceptions to or qualifications of this general rule. One is that of the creation of a general power which the donee may exercise for his own benefit, for such a power is equivalent to property. Another is that of the creation of a power of distribution amongst charities. A third is that of the creation of a power of selection amongst individuals or a class of individuals who are pointed out as the beneficiaries: see Houston v. Burns [1] .
This Court had occasion to consider the theoretical basis for the treatment of the creation of a power of appointment as a testamentary disposition in Tatham v. Huxtable [2] . Fullagar J. says [3] :
It seems quite consistent with legal principle to say that the creation by will of a general power of appointment (which has been said to confer the equivalent of ownership) is a testamentary disposition of property. It also seems consistent with legal principle to say the same of the creation of a special power of appointment among a class, where the class is described with certainty and (as in the normal case) there is, unless and until the power is exercised, a trust for the class or for persons who are to take in default of appointment. Where there is, as a matter of construction, no such trust, there does seem to be a departure from principle if we say that the creation by will of a special power to appoint among a class is a testamentary disposition of property, but to say so represents a natural enough "latitude" of view, which is perhaps characteristic of a system which has never regarded strict logic as its sole inspiration. Unless, however, there is a class designated with certainty, to say that the creation of a power to select beneficiaries amounts to a testamentary disposition of property is not merely to relax the principle to meet an exceptional case but to deny the principle absolutely.
