8:00 – 8:45 Registration – coffee and tea upon arrival

8:45 – 9:00 Welcome – Special Announcement by Michael Kitzen – CEO, JURIS and Jean-Rémi de Maistre – CEO, Jus Mundi

9:00 – 10:30 Working Session 1Initial Organization of the Arbitral Proceeding and Pre-Hearing Activities

Leader: Nikolaus Pitkowitz – Partner, Pitkowitz & Partners (Vienna)

Prof. Milena Djordjevic – University of Belgrade
Shelby Grubbs – JAMS
Mark Morril – Independent Arbitrator (New York)
Colm Ó hOisín S.C. – Independent Arbitrator (Dublin)
Prof. Patricia Shaughnessy – Stockholm University

Discussion Topics:

  • Is data protection becoming a standard item on the agenda for the CMC? And are parties and arbitrators genuinely engaging in the process, both before and during the procedure?
  • What are best practices in relation to virtual hearings; are these now the default for case management conferences? When is it appropriate for the arbitrators to require these over objection of a party?
  • What are best practices in relation to cyber security, and how can we balance security demands and practical considerations, recognizing the wildly differing expectations and preferences of all participants in an arbitration.
  • Practicalities of submissions: is sufficient thought given to optimizing the shape and form of submissions including numbering, hyperlinking, etc? What works best for one party or even both, may not be optimal for the arbitrators. How should their interests be balanced and is this adequately and transparently addressed for instance in the CMC?
  • Is sustainability the new diversity? Should we aim for comprehensive, industry wide standards based on more research and clear guidelines on the carbon footprint of arbitration or start with small steps regardless?
  • Third-party funding: at what stage should funding be disclosed and have standards developed sufficiently to allow sensible disclosure?
  • There is increasing guidance on the use of tribunal secretaries, both in institutional rules and guidelines and in case law. Is practice changing and how can practice be improved further?

10:30 – 11:00 Networking Coffee/Tea Break

11:00 – 12:30 Working Session 2Effective Presentation of Evidence – Focus on Damages in Complex Cases

Timothy G. Nelson – Partner, Skadden, Arps, Slate, Meagher & Flom (New York)
Lawrence Newman – Of Counsel, Baker McKenzie (New York)
Stefan Riegler – Partner, Wolf Theiss (Vienna)

Discussion Topics:

  • Procedures for best presenting complex damages evidence
    avoiding ships passing in the night.
  • When are tribunal-appointed experts useful; should they always appear at a hearing and be subjected to questions about his or her conclusions?
  • Do the Prague Rules add anything, or is there a predominating style of taking evidence in international arbitration, i.e., have we arrived at a Lex naturalis arbitri void of cultural differences?
  • Presentation of evidence by videoconference. Is this effective? The future?
  • Is it always necessary to have an oral hearing? When is summary disposition permissible (or necessary)?
  • Who controls the length of a hearing? Should arbitrators impose their views or defer to the parties?
  • Are there too many witnesses, too many documents – is advocacy lost among the detail?
  • How can the tribunal or parties control tactical decisions by parties not to cross-examine key witnesses?
  • Is witness conferencing effective? Is this only for experts? Are there particular circumstances when it is most appropriate? Inappropriate?

  • Is service as a Tribunal secretary useful?  Necessary?

– Partner, Brown and Page (Geneva)
Cecilia Carrara – Partner, Legance (Rome)
Calvin Hamilton – Arbitra International (London)
Inka Hanefeld – Hanefeld Rechtsanwälte Rechtsanwaltsgesellschaft mbH (Hamburg)
Luis Martinez – Vice President, AAA-ICDR (New York)

Discussion Topics:

  • Are there best practices as to how a Tribunal should organize its work? Should the chairman be delegated all procedural responsibilities? Or, if less, what should the chairman have delegated to him or her? Does the efficiency of the arbitration as to the delivery of the award depend entirely on the chairman? What can the wing arbitrators do to increase efficiency and assure quality?
  • To what extent should, or must, arbitrators disclose that they are using secretaries? If the arbitrators want to use secretaries and disclose their identity and involvement, how should they do it? Are arbitrators complying with the ICC’s note applicable to arbitrators and secretaries? What can parties and counsel do if they are not aware of certain arbitrators’ practices in this regard until after they appoint them? Or the chairman, whom they may not have appointed?
  • What can be done if an arbitrator is not doing his or her work as the case proceeds or is not paying attention in the course of the proceedings? What if this is the chairman?
  • Should the arbitrators deliberate on the award  immediately after the final evidentiary hearing? After the receiving the post-hearing briefs?  After post-hearing oral argument? Should the arbitrators meet in person? Or by telecommunication? Should arbitrators discuss among themselves the merits of the cases as they proceed? Should such discussions be mandatory? Avoided? Casual or structured (for example, “What did we learn today?”).
  • What should the third arbitrator do if the other arbitrators discuss the case or meet without him or her?
  • Compromises – how imperfect is a unanimous award? Should the tribunal accommodate the potential dissenting arbitrator? If so, how?  For example, with respect to the award of legal fees? What does a dissent accomplish?
  • When should, or may, the arbitrators rule on the basis of theories or arguments that the parties have not made?  What if the arbitrators believe that parties have not understood the precedents they cite, or the facts they refer to, in the same way as the arbitrators do? When should the arbitrators go to the parties and ask for their comments?  Should there be a difference between legal and factual issues?
  • What should the arbitrators do if they do not understand certain expert testimony? For example, damages evidence? Should they ask the parties for comments? What if they are working under a deadline to get the award out? Or they don’t want to confess their inability to understand the evidence?
  • To what extent may arbitrators do their own research on matters of general knowledge, such as how certain machines in the case actually work? Or how certain financial investments function?
