CONSENT

In law, consent is understood to be a free and deliberate act of a rational being. It is invalidated by any undue means - intimidation, improper influence, or imposition - used to obtain it. The mentally incapable, children, etc, cannot give legal consent; neither can persons in a state of absolute drunkenness, though partial intoxication will not afford legal ground for annulling a contract.
