 The UN has permitted Palestine to title its representative office to the UN as "The Permanent Observer Mission of the State of Palestine to the United Nations".Palestine has started to retitle its name accordingly on postal stamps, official documents and passports; moreover, it has instructed its diplomats to officially represent "State of Palestine", as opposed to the "Palestine National Authority".Additionally, on 17 December 2012, UN Chief of Protocol Yeocheol Yoon decided that "the designation of 'State of Palestine' shall be used by the Secretariat in all official United Nations documents", thus recognising the PLO-proclaimed State of Palestine as being sovereign over the territories of Palestine and its citizens under international law.
