The Security Council commended the countries participating in SFOR to continue their operations for an additional twelve months; it would be extended beyond this date if warranted by the situation in the country. It also authorised the use of necessary measures, including that of the use of force and self-defense, to ensure compliance with the agreements and the safety and freedom of movement of SFOR personnel. At the same time, the mandate of UNMIBH, which included that of the International Police Task Force (IPTF), was extended until 21 June 2002.
