Prima facie when a cheque is taken for the price of goods, or for that matter in respect of any other debt contracted, it operates as conditional payment. The condition is that the cheque be paid on presentation: if it is dishonoured the debt upon the original consideration revives. The rule is, of course, an old one and the presumption applies to other negotiable instruments as well as to cheques, although perhaps not necessarily with the same strength. Not unnaturally it is sometimes said that the remedy for the primary debt is suspended; but this has no different meaning, for the suspension is the consequence of the conditional nature of the payment. In Bottomley v. Nuttall [1] , Williams J. describes it as "the true doctrine upon which this branch of the law is founded, viz. that, in the case of a money demand, if the creditor accepts a bill or note for and on account of the debt, that operates as a conditional payment" [2] . On the same page in reiterating the rule of law he says that it is established in all the cases and is summed up by Maule J. in Belshaw v. Bush [3] . In Allen v. Royal Bank of Canada [4] Lord Atkinson, speaking for the Privy Council, cited a passage from Byles on Bills expressing the rule in terms of the suspension of remedy. As some reliance has been placed on this as pointing against the principle of conditional payment it may be as well to refer to the formulation which Byles J. made judicially of the rule in Bottomley v. Nuttall [1] . His Lordship said: "it is the first learning that taking a bill for and on account of a debt does not operate as an absolute discharge of the debt. At the most it is only a conditional payment, which is defeated by the subsequent dishonour of the bill, whether total or partial" [1] . In the well-known judgment delivered by Lush J. for the Exchequer Chamber in Currie v. Misa [2] this passage occurs: "the title of a creditor to a bill given on account of a pre-existing debt, and payable at a future day, does not rest upon the implied agreement to suspend his remedies. The true reason is that given by the Court of Common Pleas in Belshaw v. Bush [3] as the foundation of the judgment in that case, namely, that a negotiable security given for such a purpose is a conditional payment of the debt, the condition being that the debt revives if the security is not realized" [4] . In the present case therefore once the cheque was taken by or on behalf of a seller of the goods the debt was conditionally satisfied; accepting the cheque could not amount to giving credit, but once the cheque was dishonoured the debt revived and of course a cause of action also arose upon the cheque. There was at that stage no question of giving or obtaining credit.
