Reports of Administering Powers

Articles 87 and 88 of the Charter concern the reports of the administering authorities. These reports responded to a questionnaire prepared by the Trusteeship Council on the "political, economic, social, and educational advancement of the inhabitants of each trust territory".

  • There is no document series symbol
  • Only the note transmitting the report was produced as a UN document
    • Reports were usually publications of the administering power and only a few copies were available for consultation at the UN
    • May be available from the national archives of the administering power, or for consultation at a UN Library
  • For citation to the note transmitting the report, see the relevant box on the page for the territory of interest

The Trusteeship Council sent visiting missions to territories. For each visiting mission, the Council adopted a resolution setting the terms of reference for the mission. In general, each territory was visited about every three years.

  • Issued as Supplements to the Trusteeship Council Official Records (TCOR)
  • Often visited several territories in a region
