The Permanent Mandates Commission (PMC) was the commission of the League of Nations responsible for oversight of mandated territories. The commission was established on 1 December 1920 and was headquartered at Geneva.
The existence of the Commission was stipulated in Article 22 of the League of Nations Covenant: "A permanent Commission shall be constituted to receive and examine the annual reports of the Mandatories and to advise the Council on all matters relating to the observance of the mandates."[1][2]
Even though the PMC was composed of members from imperial and foreign policy establishments, the organization did act independently of states and established norms that constrained the behaviors of colonial powers.[3] The PMC was the first instance that either France or Britain had been subjected to any kind of imperial oversight.[4] The PMC played a key role in establishing that the mandates could not be annexed by the colonial powers. The PMC helped to establish that the mandates had a unique status under international law.[5]
