The Security Council Resolution 39 of April 1948 established a UN Commission (United Nations Commission for India and Pakistan — UNCIP) to mediate between India and Pakistan in order to bring about a cessation of fighting in Kashmir and to make arrangements for a popular plebiscite. After negotiations with the two sides, the Commission passed a three-part resolution in August 1948 and subsequently added a 'supplement'. The three parts dealt with ceasefire, terms for truce, and procedures for negotiation regarding the plebiscite.
