United Nations Security Council Resolution 127, adopted on January 22, 1958, dealt with complaints by Jordan regarding Israeli activities between the armistice demarcation lines. Taking into account a report by the Acting Chief of Staff of the United Nations Truce Supervision Organization in Palestine, the Council noted that neither Israel or Jordan enjoyed sovereignty over any part of the zone. The Council then directed the Chief of Staff to regulate activities within the zone so that Israelis would not be allowed to use Arab-owned properties and vice versa, and directed the Chief of Staff to conduct a survey of property records with a view to determine property records with a view to determine property ownership in the zone.
