Incommunicado, Unacknowledged and Secret Detention under International Law (2006)

International, regional and national mechanisms are investigating allegations that individuals have been transferred from locations around the world to secret detention and interrogation sites controlled by one State but physically located in the territory of one or more other States.

This paper explains why such activities would constitute a violation of international law, entailing international legal responsibility both for States engaging directly in such detentions and transfers and for those that assist, tolerate, or fail to adequately investigate or prevent such actions on their territory.
