We think that the conditions on which s. 13 is itself expressed to operate exist in this case. The purchaser should, we think on the assumption that s. 13 applies to the contract at all be held to have "paid off an amount from the consideration" in the shape of the deposit, and to have "failed to continue to comply with the terms of the contract" within the meaning of the section. It remains, however, to consider whether the contract in this case is one to which s. 13 applies at all. It applies, in our opinion, only to "contracts of sale of land" as defined in the Act. The term "contract of sale of land" is defined by s. 3 as meaning: "An agreement for the sale and purchase of land where the terms of the sale provide that the payment by the purchaser for the land shall be extended over a period of time: the term also includes any such sale of land where the instrument of sale is not a registrable instrument under The Real Property Acts, 1861 to 1887." This muddled and dubious "definition" is of a piece with the rest of the Act. Both branches of it raise difficulties. With regard to the first branch, the words "extended over a period of time" suggest that the draftsman had in mind a contract under which a balance of purchase money over and above a "deposit" is payable by instalments, as distinct from a contract under which the balance is payable in full after a period regarded as reasonable for investigation of title, requisitions, &c. The language used is perhaps not incapable of including the latter class of case as well as the former. But, if it does include the latter class of case, it includes, practically speaking, all contracts for the sale of land, so that no "definition" was necessary. Is it possible, on the other hand, to give to the words "extended over a period of time" any definite meaning which will exclude the latter class of case? The second branch of the "definition" is even more difficult: it is indeed practically unintelligible. If the word "such" merely refers back to "any agreement for the sale and purchase of land", then the second branch of the definition merely means "and all other contracts for the sale of land", for no contract is registrable under the Torrens system. If, on the other hand, it refers back to some limited (though perhaps extremely wide) class of contracts mentioned in the first branch, then it adds nothing whatever to the definition.
