I. In the field of international law every subject generally acts in person, through its own organs, without resorting to cooperation with other subjects. However, international practice shows that members of the community of nations sometimes act on behalf of other members, with the legal effect that the transactions performed by the acting subject in the name and for the account of the other have for the latter the same legal consequences as if it had acted in person. This happens, for example, when a state, duly authorized, concludes through its own organs a treaty for another state: the latter is thus bound by the treaty exactly in the same way as if it had concluded the treaty itself, through its own organs. This legal phenomenon implies a split between the immediately acting international person and the person to whom the legal effects of these acts are imputed.
