For the purpose of the court-appointed arbitrator by the president of the tribunal, jurisdiction is founded by the arbitration clause designating the seat of the arbitration within that district; in the absence of an express determination of the seat, jurisdiction is determined by the place of conclusion of the arbitration agreement.
An alleged breach of the rotation principle in the appointment of an arbitrator does not bear on the validity of the presidential appointment order and does not constitute grounds for its revocation.
Complaints relating to the conduct of the arbitral proceedings — such as the failure to consolidate proceedings and the selection of documents on which the decision is based — fall outside the scope of the tribunal's review at the stage of appointment of the arbitrator, as they pertain exclusively to the ongoing arbitral proceedings.
