The primary judge found that the appellant signed the extension of the option in the belief that it was a receipt, unaware that it was an extension of the option, having been told by the agent that he "must sign" the document. His Honour also found that the appellant did not read the document and that he was incapable of reading and understanding it. The manner in which two of these findings are expressed does not conform precisely with the evidence on which they are based, that is, the testimony of the appellant. The statement that Mr. Clements said that the appellant "must sign" the document is a reference to the appellant's account of events when Mr. Clements said to him, "Sign it that you received $50". No doubt all his Honour sought to convey by his finding was that in terms the agent gave an instruction, and did not make a request, to sign. The Court of Appeal found more difficulty with his Honour's finding that the appellant signed in the belief that the document was a receipt. In fact nowhere in his evidence did the appellant explicitly state that this was his belief, although there is material in the appellant's evidence which, properly understood, testifies to the existence of such a belief. First, there is the evidence-in-chief to which we have already referred. Then there are the following questions and answers in cross-examination recorded in the transcript.
