The validation of agreements in law is dependant to some conditions. The causes that invalidate treaties are generally; “treaties made by unauthorised people”, “failure of intentions” and “violation of order rules (iuscogens) of international law”. The legal effect of an agreement becomes invalid, invalidity (nullity, impediment in law) in other words not to come in to operation from the moment of enforcement.
