I agree in the view that the gift which the testator makes to his son, Walter Charles, of a right to purchase the testator's "Dairy Creek" property is valid and that this option to purchase was duly exercised. In my opinion the trust of the "Dairy Creek" property which the testator declared by the will for his son, Norman, does not give him an absolute interest. Accordingly, I feel that I need not encounter the question whether the option to purchase is void as being a total or substantial restraint on the alienation of the property by Norman. I think that you cannot infer from the fact that Walter Charles takes under the trust declared for him of the "house property" an absolute interest, that it is the testator's intention to give a similar interest to Norman in the "Dairy Creek" property; it was by reasoning substantially of this nature that the decision under appeal was reached. It seems to me to be plain from the language of the will, and the dispositions of these properties, that it is the intention of the testator to give an absolute interest in the "house property" to Walter Charles, but an interest modified by the option to purchase in the "Dairy Creek" property to Norman. The words providing for the option to purchase do not, in my opinion, import a condition subsequent but rather the limitation of an equitable interest in the "Dairy Creek" property. "Words expressing a condition may be treated as being words of limitation or merely creating a trust or charge" Halsbury's Laws of England, 2nd ed. vol. 34, p. 363; (See also Cheshire's Modern Real Property 7th ed. (1954) p. 309). The option to purchase is in the nature of a conditional gift of the "Dairy Creek" property (see Halsbury's Laws of England, 2nd ed. vol. 34, p. 34). As I have already said, the devise of the right to purchase the property creates an equitable interest in the land. (See Hutton v. Watling [1] and the cases therein cited). The "Dairy Creek" property, in the hands of Norman, is bound by this interest. The words creating the option to purchase are an executory devise of such interest. The interest which Norman takes under the will in the property in question is a determinable equitable interest; it determines upon the due exercise of the option to purchase. Subject thereto, it is an equitable interest in fee simple. The testator has by the will devised the whole of his estate in the "Dairy Creek" property, and carved out of that estate the determinable interest given to Norman and the right which is given to Walter Charles to purchase it. The testator by the disposition he made of the "Dairy Creek" property manifests his intention to mould the equitable estate in that property into the determinable interest, given to Norman, and the option to purchase given to Walter Charles. (See Cheshire's Modern Real Property, 7th ed. (1954) at p. 49). The gift of the option of purchase to Walter Charles cannot, in my opinion, be impeached in principle upon the ground of repugnancy to the trust of that property which the will creates in favour of Norman. The other question is whether the option to purchase was duly exercised. I do not desire to add anything to what the Chief Justice has said on that question.
