Answer ... A person who is not party to the arbitration may participate in the proceedings as a party if the claim can be resolved only with its participation and if it submits a written a statement regarding its acceptance of the jurisdiction of the tribunal.
In addition, upon the request of any party, the tribunal will inform a person with a legal interest of the outcome of the arbitration proceedings on intervention. The intervener may submit evidence and participate in the hearing and in inspection procedures.
