Consideration is an essential ingredient of enforceability of agreements. Classic 19th Century definition of consideration is found in the case of Currie v Misa (1875) - 'may consist either in some right, interest, profit, or benefit accruing to the one party, of some forbearance, detriment, loss, or responsibility given, suffered, or undertaken by the other'. Pollock gives a more concise definition 'the act or forbearance of one party, or the promise thereof, is the price for which the promise of the other is bought and the promise thus is given for value is enforceable in Dunlop v Selfridge [1915]
