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 (Art. 2(1)/c, Vienna Convention). 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.
