Number of Copies
The "Request" and attached documents must be supplied in as many copies as there are other respondents, plus one for each arbitrator and one for the Secretariat (Article 3 (1) of the Rules of Arbitration).
For example, if there is one respondent and the arbitration agreement provides for three arbitrators, five copies should be sent.
If the number of arbitrators is not determined, the claimant should provide the number of copies that corresponds with its own preference as to the number of arbitrators. If necessary, the Secretariat will then seek further copies of the "Request" later in the proceedings.
