"It is quite clear that a promissory note, payable on demand, is a present debt, and is payable without any demand, and the statute begins to run from the date of it."
"Although no express reference is made to the rule in Brown's case, its existence is tacitly recognised by the distinction drawn in section 6(2)(b) between the purport on the one hand, and the effectiveness on the other, of a provision making the obligation to repay conditional on a demand for repayment. The potential hardship of the rule to which the Law Reform Committee have drawn attention is, however, mitigated by causing the six-year time bar imposed by section 5 to run, in the case of loan contracts which contain no provision for a fixed repayment date and which omit any effective provision making the loan repayable on demand, from the date of any written demand for repayment."
