How the Arrêté of 31 August 1927 (the ‘Arrêté’), adopted by the Governor-General ad interim of French West Africa, referenced in the Agreement of 28 March 1987 between Burkina Faso and Niger (the ‘1987 Agreement’), should be interpreted in relation to the demarcation of the frontier between the two countries, and to what extent the Arrêté was applicable to the frontier dispute.

Whether the Arrêté was sufficient, in reference to the 1987 Agreement, to determine the course of the frontier running from the agreed Tao astronomic marker to the River Sirba at Bossébangou, and, in any event, what the course of that frontier was and what its end point was.
What role effectivités played in determining the course of the frontier between the Tao astronomic marker and the River Sirba at Bossébangou.
How the course of the southern part of the frontier between the intersection of the River Sirba and the Say parallel and a point located to the west of the village of Tchenguiliba should be determined.
