may be called the rescission clause, in the following terms: 'But if default shall be made in due payment of the said purchase money and interest or any part thereof respectively at the respective times aforesaid the Vendor may at his option without notice to the Purchaser sell the said property and rescind this contract and any moneys paid on account of the purchase shall then be forfeited to the Vendor as and for liquidated damages."
Shortly before 14th January 1952, one of the purchasers, Mr. Holland, asked the vendor for an extension of the time for com- pletion on the ground that he was having difficulty in getting finance. An extension was agreed to, the period of the extension being fixed at a fortnight according to the vendor, but being left indefinite according to the purchasers; but for want of writing, the agreement, whatever it was, cannot be relied upon as a variation of the contract. An offer by the vendor, made about 12th February 1952, to release the purchasers from their obligations on payment of a commission was rejected, and a further attempt to get the necessary finance was promised by the purchasers. Early in March 1952 the vendor told the purchasers' solicitor, in response to an inquiry by the purchasers, that he was prepared to allow £250 of the price to be secured by a second mortgage, and the solicitor promised to get into touch with Mr. Holland. About a fortnight later the vendor saw the solicitor again, and the latter then said
'Mr. Holland is not going on with the contract."
On 17th March 1952, the vendor gave the purchasers a notice in writing which recited the contract of sale and the purchasers' failure to settle, and notified the purchasers that they were required to make settlement by 28th March 1952. It added: " " If settlement is not made by that date the vendor Robert Cyril Wiltshire will take proceedings against you for breach of contract." This notice the purchasers ignored, and they did not at any time retract the intimation which their solicitor had given of their intention not to go on with the purchase.
In May 1952, the vendor instructed a firm of estate agents to sell the property by public auction. The sale was advertised, in the press and by means of a board erected on the property, over a period of three weeks or a month. The property was sold on 10th June 1952 for a price which produced to the vendor the net sum of £3,102 19s. 10d. The vendor then sued the purchasers in the Local Court of Adelaide, a court of common law jurisdiction, to recover as damages £647 Os. 2d., being the amount of the difference between this sum and the price provided for in the contract. The action was tried by a special magistrate who, after allowing credit
