With great respect to the learned judges who decided those cases, I would think that the real question was not whether the power which was given was a valid power as such, but whether it amounted to a true testamentary disposition of property, or, in other words, whether it complied with the well-established rule stated by Lord Haldane in Houston v. Burns [3] and by Lord Simonds in the Diplock Case (Chichester Diocesan Fund v. Simpson [4] ). It is to be remembered that the ultimate basis of the rule lies in the Wills Act, which provides that every person may dispose of all his property by will but that no will shall be valid unless it is in writing and executed by the testator in a particular manner. It is inherent in the very nature of the power so given that it cannot be delegated or exercised by an agent for the testator, and it seems to me necessarily to follow that some powers of appointment, which would be perfectly good in any instrument other than a will, are ineffective in a will for the simple reason that they do not amount to a testamentary "disposition" of property, or indeed to any "disposition" of property at all. 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. And this is, I think, what was done both in Re Park [1] and in Re Jones; Public Trustee v. Jones [2] . When it is said in such cases that the power given is a valid power as such, as no doubt it is, the real question - the question whether there is a testamentary disposition of property - seems to me, with great respect, to be simply avoided.
