Abstract
This article examines the Annulment Procedure of ICSID Arbitration Award. Although the ICSID annulment procedure is not substantially different from arbitration procedure, it does have certain unique features. Article 52 of the Convention provides that the application for annulment must be made within 120days after the date on which the award was rendered. ICSID Arbitration Rule 50, in turn, stipulates that a request for annulment of a award must: i)be addressed in writing to the Secretary-General; ii)identify the award to which it relates; iii)indicated the date of the application; and iv)state in detail the grounds for annulment on which it is based. The grounds for annulment are limited to those in Article 52(1) of the Convention. With respect to the possibility of waiving the right to annulment in advance, commentators are divided. Some authors admit the possibility of agreements eliminating the right to request annulment. Other authors, instead, have taken the position that parties cannot waive their right to annulment in advanced because no provision in the Convention allows the parties to do so, and thus the right to request annulment is inalienable. In accordance with Article 52(4), annulment decisions must comply with the requirements for awards stipulated in Article 48. Therefore; i)the committee decide questions by majority; ii)the decision must be in writing and must be signed by the members of the committee who voted for it; iii)any member of the committee may attach his individual opinion to the award; and iv)ICSID must not publish the decision without the consent of the parties. Finally, under Article 52(4), parties are not allowed to request the interpretation, revision, or annulment of a decision on annulment. Even if the committee allegedly manifestly exceeded its powers or engaged in any conduct sanctioned by Article 52(1), the parties cannot request the annulment of the decision on annulment.
