The article explores China International Economic and Trade Arbitration Commission (CIETAC) arbitrations seated in Vienna and addresses legal implications of the interplay between the CIETAC Arbitration Rules and the Austrian arbitration law in connection with document production, additional rounds of written submissions/late submissions of new facts and evidence, and crossexaminations including witness preparation and coaching. The Austrian arbitration law vests the arbitral tribunal with the power to conduct the proceedings in such a manner as it considers appropriate. As a consequence, the arbitral tribunal is authorized (unless the parties agree otherwise) to apply the Rules on the Taking of Evidence in International Arbitration of the International Bar Association (IBA Evidence Rules), the CIETAC Guidelines on Evidence (CIETAC Guidelines) or the Prague Rules. As a consequence, the article also highlights some of the most important differences between the IBA Evidence Rules, the CIETAC Guidelines and the Prague Rules. US-style discoveries or fishing expeditions violate Austrian public policy. Cross-examinations are allowed, but witness coaching and leading questions are available only to a limited extent. The article provides a proposal for new provisions to be included in CIETAC’s ProceduralOrder No. 1 covering additional rounds of written submissions, the late submission of evidence and the introduction of new facts.
