The Convention on the Privileges and Immunities of the United Nations, passed by the United Nations General Assembly on 13 February 1946 in New York, and sometimes referred to as the "New York Convention", defines and specifies numerous issues relating to the status of the United Nations, its assets, and officials, in terms of the privileges and immunities that must be granted to them by its member states. As of August 2013, it has been ratified by 160 of the 193 UN member states.
