there was a purchase, or at least an acquisition, of land within the meaning of the Regulations; that such a transaction is prohibited by the Regulations, and is therefore illegal and ineffective and that reg. 10 applies only to past and completed transactions, or alterna- tively (if no contract was made) has no application to an unaccepted offer. It is also argued for the defendants that the " exercise of the option " was not the acceptance of an offer which the executors must be regarded as having made, but, on the other hand, was the making of an offer to the executors which they have not in fact accepted, so that no contract (or transaction) has resulted.
A distinction should be drawn between an option to purchase given inter vivos for value and an option given by will. Options of the first class are binding contracts. Varying opinions have been expressed upon the question whether such an option agreement vests an equitable interest in the property in the optionee before it is exercised See Goldsbrough, Mort &Co. Ltd. v. Quinn (1), where Griffith C.J. said that the option did give an interest in property (2). O'Connor J. was not definite on this point. Isaacs J. took another view (3)-See comment made by Isaacs J. in Carter v. Hyde (4). See also Commissioner of Taxes (Q.) v. Camphin (5); Trustees Executors &Agency Co. Ltd. v. Federal Commissioner of Taxation (6). In Halsbury's Laws of England, 2nd ed., vol. 6, at p. 109, and vol. 20, at p. 65, the references to the creation of an equitable interest in property over which an option may be exercised refer to the exercise of the option, and not to the mere existence of the option agreement.
There are statements that options given for value are them- selves property in a sense which is not very precisely defined In re Cousins Alexander v. Cross (7), where an option which was held to be personal to the optionee, exercisable by him only, and not assignable, was nevertheless, because it was of value, said to be property in one sense." See, further, Carter v. Hyde (8); Re Busby Busby v. Busby (9).
But an option given by a will is very different in legal character from an option arising under a contract. Such an option is plainly not a contract. It is unilateral. It is not an offer made by the testator during his lifetime capable of acceptance after his death so as to become a contract under which the testator can be held to have become liable.
