Full powers is  a formal document emanating from the competent authority of a state designating a person or persons to represent the state for negotiating, adopting or authenticating the text of a treaty, for expressing the consent of the state to be bound by a treaty, or for accomplishing any other act with respect to a treaty.Before the start of the formal negotiations of a treaty, normally there is a reciprocal examination of the full powers in order to avoid any trouble resulting from negotiation with a representative, not duly authorized to negotiate. Through the conclusion of less formal agreements between the departments of two governments, the practice of production of full powers by states is now increasingly dispensed with.
