Слово встречается в следующем контексте:

The IAC is entitled to support the activities of the COUNCIL and the execution of its decisions. The 1991 Agreement provides that the States-Parties participate in the IAC activities "through their plenipotentiaries". In practice they are the same plenipatentiaries which are appointed by the States to the COUNCIL and which to an extent are acting "in a duel quality".
