The National Agency for the Prevention of Torture is composed of two institutions: the Federal Agency for the Prevention of Torture and and the Joint Commission of the Länder.
The Federal Agency monitors the facilities which fall under the jurisdiction of the Federal Republic of Germany, namely detention facilities of the Federal Police, those of the Federal Armed Forces and the Customs. It is also responsible for monitoring forced returns flights.
The Joint Commission monitors facilities which fall under the jurisdiction of the federal states (Länder), which mainly refer to judicial, police and psychiatric facilities. These are the vast majority of places of detention in Germany.
The National Agency developed its rules of procedure.
