2. In that year, the appellant received from the Commissioner for Railways (N.S.W.) an amount of 12,350 pounds in full settlement of a claim for damages which was the subject of an action then pending in the Supreme Court of New South Wales in which the appellant was the plaintiff and the Commissioner for Railways was the defendant. The claim was in respect of damage done on a grazing property of the appellant, on 24th January 1952, by a fire which had commenced on land of the defendant Commissioner. The appellant's case, as appears from the declaration which he filed in the action, was that the defendant Commissioner was liable to him in damages, either for not having taken reasonable care in relation to the fire or on the principle of Rylands v. Fletcher (1868) LR 3 HL 330 . The amount claimed in the writ was 30,000 pounds. Before the issue of the writ the appellant had supplied particulars, under a number of heads, of the damage he had sustained and of the amounts which he intended to claim in respect of each head of damage. The total of these amounts was 30,240 pounds. The settlement of the action was reached after negotiations in which the Commissioner for Railways was represented by a Mr. Cameron. He was a valuer employed by the Commissioner for Railways, and had visited the appellant's property as early as November 1952 to make his own assessment of the damage caused by the fire. Discussions without prejudice took place first between Mr. Cameron and a brother and a nephew of the appellant, and ultimately between Mr. Cameron and the appellant himself. At their conclusion Mr. Cameron, having consulted the Assistant Solicitor for Railways, told the appellant that the Commissioner for Railways was prepared to offer a lump sum of 12,350 pounds, together with costs, to settle the case. He gave the appellant no information as to how this sum had been arrived at, and the appellant, without knowing how it had been arrived at, agreed to accept it. Payment was made to the appellant on 28th June 1955, after he had signed a document expressing his agreement to accept the sum "in full settlement of all claims for damage arising out of" the fire which has been referred to.
