[12] On the first of these matters, therefore, all parties are at one. The contract must, so far as possible or permissible at law, be given operative effect as the agreement of the parties. The law should not earn the reproof of being the destroyer of bargains. If, as is the case, it is not legally possible or practicable in law to give literal effect to cl 12(c) as providing for transfer of the "bare legal estate" in the Seller's Block, then it is to be construed, as its terms suggest, as an agreement to transfer to the buyer the registered title for the seller's estate in the whole of the area, subject however to the obligation on the part of the buyer to retransfer or reconvey to the seller the title to the Seller's Block once it was lawfully excised by registration of a plan of survey authorising the subdivision. It is not, however, at this preliminary stage but at the next step that the issue arises. What was submitted by the sellers, and accepted by the learned judge in para [42] of his reasons, is that there was under each of the contracts a sale of the Seller's Block; or, in other words, that under each such contract the seller had agreed to sell to the buyer a "proposed allotment", being the Seller's Block, in contravention of the statutory prohibition in s 8(1)(a) of the Land Sales Act.
