The ICSID Additional Facility Rules define the scope of the Facility. Disputes between a State and a national of another State are eligible for arbitration under the Facility if:
  • they are investment disputes between parties, one of which is not an ICSID Member State or a national of an ICSID Member State; or
  • they do not directly arise out of an investment between parties, at least one of which is an ICSID Member State or a national of an ICSID Member State.
Because such disputes are not covered by the ICSID Convention (see Article 25(1) of the ICSID Convention), none of the provisions of the ICSID Convention is applicable to Additional Facility proceedings (Article 3 of the Additional Facility Rules).
An agreement to arbitrate under the Additional Facility Rules is subject to approval by the Secretary-General under the Additional Facility Rules (Article 3) before proceedings can commence.
The Arbitration (Additional Facility) Rules govern the arbitration process from the filing of the request for arbitration onward. Approval of access to the Additional Facility Rules must be granted before the request for arbitration can be registered under the Arbitration (Additional Facility) Rules.
In addition to the provisions of the Arbitration (Additional Facility) Rules, the laws of the place of arbitration apply to the proceeding (Article 20 of the Arbitration (Additional Facility) Rules). If a provision of the Arbitration (Additional Facility) Rules conflicts with a mandatory provision of the applicable law, that law prevails (Article 1 of the Arbitration (Additional Facility) Rules).
The Administrative and Financial Regulations contain provisions concerning:
These provisions apply mutatis mutandis to arbitration proceedings under the Additional Facility Rules (Article 5 of the Additional Facility Rules).
