"...I must make some comments upon the judgment of the Court of Appeal. Leggatt LJ said that his construction was "the natural and ordinary meaning of the words used." I do not think that the concept of natural and ordinary meaning is very helpful when, on any view, the words have not been used in a natural and ordinary way. In a case like this, the court is inevitably engaged in chosing between competing unnatural meanings. Secondly, Leggatt LJ said that the judge's construction was not an "available meaning" of the words. If this means that judges cannot, short of rectification, decide that the parties must have made mistakes of meaning or syntax, I respectfully think he was wrong. The proposition is not, I would suggest, borne out by his citation from Through the Looking-Glass. Alice and Humpty-Dumpty were agreed that the word "glory" did not mean "a nice knock-down argument." Anyone with a dictionary could see that. Humpty-Dumpty's point was that "a nice knock-down argument" was what he meant by using the word "glory." He very fairly acknowledged that Alice, as a reasonable young woman, could not have realised this until he told her, but once he had told her, or if, without being expressly told, she could have inferred it from the background, she would have had no difficulty in understanding what he meant."
