 "Inequality of bargaining power" is a term used in English law to express essentially the same idea as unconscionability, which can in turn be further broken down into cases on duress, undue influence and exploitation of weakness.In these cases, where someone's consent to a bargain was only procured through duress, out of undue influence or under severe external pressure that another person exploited, courts have felt it was unconscionable to enforce agreements.Controversy exists as to whether a contract should be voidable simply because one party was pressured by circumstances wholly outside the other party's control.
