Under the terms of the 1990 Treaty on the Final Settlement with Respect to Germany, the Four Powers renounced all rights they formerly held in Germany, including Berlin. As a result, Germany became fully sovereign on March 15, 1991. After Germany joined the United Nations, there had been disagreement as to whether articles 53[29] and 107[30] of the UN Charter, which named Germany as an "enemy state", still applied, but these articles became irrelevant when the Four Powers renounced their special rights in the 1990 treaty,[31] and they were formally recognized as obsolete by a UN General Assembly resolution[32] in 1995.[33]
