The government was required to nominate two from the Messiriya and the SPLM/A from the neighbouring Dinka tribe in the Abyei area. The experts in the commission were to consult the British and other relevant archives. The ABC was instructed to determine the boundary to be included in the special administration. The commission was expected to deliver its final report by the end of pre-interim period or 9 July 2005.
