"Clause Y also directs that one-tenth of the profits is `to be distributed between and amongst such of the employees for the time being engaged in the said business and in such proportions in all respects as my trustees shall in their absolute discretion think fit.' In the proceedings in 1907 Street J. answered a question asked by declaring `that the trust in favour of the employees for the time being engaged in the said sweep business . . . is not void for uncertainty or otherwise.' It will be observed that his Honour expressly refers to this provision as creating a trust and holds that it is not void for uncertainty or otherwise. Such a trust is not charitable in character; it is intended to continue for an undefined time; and the beneficiaries under it consist of a class of persons fluctuating from time to time. It might be thought therefore that the gift was void but the contrary decision has been reached in litigation between all the parties who are now represented before the court and this court must necessarily accept the decision that the provision in question is not void for uncertainty or otherwise. This decision must, I think, be construed as excluding any objection based on the rule against perpetuities. It means that at the time when the question arose, there was nothing invalid in the provision. The validity of such a provision, if it is valid, cannot be affected by effluxion of time. It might, have been otherwise if the clause had provided for the accumulation of any of the profits. The interest of the employees, however it may be defined is an interest only in relation to one-tenth of the profits while the sweep is a going concern. A later provision in the will (clause DD) provides for the division of the proceeds of the sweep business if it is wound up. The employees take no benefit under clause DD, though, as will be seen, the persons specifically mentioned in clause Y, or their widows, do benefit under clause DD."
