Nemo Contra Factum Suum Venire Potest is a Latin maxim which means ‘no one can go against his own act’. When an act has once been performed, which is binding on the actor, s/he cannot at will depart from that act or do anything contrary to it. Thus if one has submitted a question to arbitration s/he cannot resile therefrom. S/he cannot validly do anything to prevent the submission procedure. An agent who enters into a contract on behalf of his principal cannot subsequently depart from his contract on the ground that he had no authority from the principal to enter into it. That might be a good defence in the mouth of the principal, but would not be available to the agent
