Legal Principle: Two or more persons are said to consent if they agree upon the same thing in the same sense. Consent is said to be free when it is not caused by coercion, or undue influence, or fraud, or misrepresentation or mistake. When consent to an agreement is caused by coercion, undue influence, fraud or misrepresentation, the agreement is a contract voidable (rescindable or terminable) at the option of the party whose consent was so caused. However, when consent to an agreement is caused by mistake as to a matter of fact essential to the agreement, the agreement is void.Factual Situation: X threatens to gun down Y, if he (Y) does not sell his property worth ` 20,00,000 for merely ` 1,00,000.
