A five-member Tribunal has been fully constituted to hear the arbitration between the Government of Sudan and the Sudan People’s Liberation Movement concerning the delimitation of the Abyei Area pursuant to an Arbitration Agreement deposited with the PCA on July 11, 2008.

The members of the Tribunal are H.E. Judge Awn Al-Khasawneh of Jordan and Professor Gerhard Hafner of Austria (appointed by the Government of Sudan); Professor W. Michael Reisman and Judge Stephen W. Schwebel of the United States of America (appointed by the Sudan People’s Liberation Movement/Army) and Professor Pierre-Marie Dupuy of France (appointed as presiding arbitrator by the Secretary-General of the Permanent Court of Arbitration (“PCA”) in consultation with the four party-appointed arbitrators).

The PCA International Bureau is acting as registry and providing administrative support.
