Take the Witness: Cross-Examination in International Arbitration

6 September 2019 – Hamburg, Germany

Hamburg Chamber of Commerce (Handelskammer Hamburg)

Program Information

This conference will bring together a group of some of the best known and experienced practitioners in the field of international arbitration, both advocates and arbitrators, to discuss, and then demonstrate, how to cross-examine witnesses in an international arbitration. The program will make it clear that not all international arbitrations – and not all witnesses – are the same.

All conference attendees will receive a complimentary copy of the all-new Second Edition of Take the Witness: Cross-Examination in International Arbitration. This work, first published in 2010, has been widely praised and features insights from leading practitioners worldwide. It has provided a framework for numerous past interactive seminars on cross-examination, and we are excited to present this latest seminar in the Hamburg, Germany.

Guidelines, tactics, techniques, ideas and advice to be followed or at least considered in conducting cross-examination will be discussed, analyzed and demonstrated, such as:

  • Fundamentals of cross-examination.
  • Cross-examination before international tribunals.
  • Experienced international arbitrators’ views of the effectiveness of cross-examination.
  • Dealing with “impeachment” issues (faulty memory, bias, contradictory testimony).
  • Cross-examination before civil law arbitrators.
  • The differences between cross-examining fact witnesses and cross-examining expert witnesses.
  • Handling written witness statements and effectively cross-examining on them.
  • How to influence and persuade arbitrators – what works, what doesn’t.
  • Using documents effectively.

For the newer entrant to international arbitration, the conference will be a source of learning, for the experienced, it will serve as a refresher of advocacy skills. Participants will benefit from better understanding and appreciating the nuances and process of successful cross-examination in international arbitration. Knowledge gained at this conference will serve to render participants more effective cross-examiners, regardless of prior experience.

9:00-9:15    Welcome

9:15-9:45    Introduction: Basics of Cross-Examination – Lawrence W. Newman and Timothy G. Nelson

9:45-10:00    Overview of Morning Program; Further Tips – Lawrence W. Newman

The morning sessions will feature two cross-examinations of the same fact witness before a mock three-member tribunal, with other faculty members as commentators. The cross-examinations will not be done through a script. Rather, the same witness will be cross-examined by two separate lawyers who will have prepared their outlines independently. The second cross-examiner will not have the benefit of having heard the first cross-examination, and may therefore apply a different style and technique from that used by the first cross-examiner. The cross-examiners will make use of correspondence and other prior statements of the witness that are contained in the background materials (scenario) that will be made available in advance to the examiners, the audience, and the Tribunal.

The two sets of cross-examinations will each be followed by comments and critiques from tribunal members, faculty commentators, and members of the audience.

10:00-11:00    First Cross-Examination of a Fact Witness

Angeline Welsh will cross-examine the witness, the CEO of the Claimant, played by Elke Umbeck, before a tribunal composed of Jonathan Blackman (Chair), Rory O. Millson, and Anke Sessler.

11:00 -11:15    Morning Break

11:15-12:15    Second Cross-Examination of a Fact Witness

Ruth Byrne will cross-examine the same witness, played by Sabine Konrad, before the same tribunal composed of Rory O. Millson (Chair), Jonathan Blackman, and Anke Sessler.

12:15-12:45    Discussion/Post-Mortem of Fact Witness Cross-Examination – led by Timothy G. Nelson

12:45-1:45    Networking Lunch

1:45-2:00    Introduction to Afternoon Program: Cross-Examination of an Expert – Timothy G. Nelson

The afternoon session will follow a similar format, except with an expert as the witness.

2:00-3:00    First Cross-Examination of an Expert Witness

Hamburg, Germany’s second largest city, has much to offer. The Hanseatic city, traditionally an international trading and shipping hub, is powered by its port, Europe’s third largest. The port is also an important hub for cruise liners, welcoming over 200 cruise ships per year. Perched on the Elbe river and a located a mere two-hour drive from the North Sea, Hamburg is defined by its maritime character.

Some sightseeing highlights include strolling around the city’s picturesque downtown area, which is anchored by an imposing city hall from the late 18th century (the Rathaus) and the ultra-chic shopping avenue “Neuer Wall.” Hamburg has various lakes (the Innenalster and Aussenalster) lined with elegant shopping areas, waterside cafés, and parks. The Speicherstadt, a warehouse complex developed in the late 1800s, now a UNESCO World Heritage site, is a short walk from Hamburg’s downtown area. Boat tours of the city’s port offer visitors a fascinating and up-close introduction to the global shipping and trading industry. The “Treppenviertel” inBlankenese is a picturesque and historic fishing village balanced over the Elbe, easily reachable from the downtown area by water taxi.

Hamburg offers many opportunities to enjoy the arts. The recently inaugurated Elbphilharmonie is being lauded worldwide as an architectural gem and acoustic feat. In addition to the Elbphilharmonie, Hamburg boasts anopera, the classically beautiful Laeiszhalle, and many more venues for music concerts, including, for those curious about the city’s thriving electronic music scene, renown nightclubs. In addition, Hamburg has a thriving musicals scene. It has hosted the Lion King for over 15 years and offers a range of other musicals to enjoy. (Note for non-German participants: These musicals are in German.)

Hamburg also boasts an exciting culinary scene, including surprising pockets of excellent Italian, Portuguese, and Spanish restaurants. Traditionally, the city’s cuisine is “fish-forward.” From fish sandwiches sold at stands along the Elbe’s rustic water taxi docks (Landungsbrücken) to haute seafood at the city’s iconic Fischereihafen restaurant—there’s something for everyone, and it often comes with a view of the port.

Hamburg is a city that melds elegance and grit. It is as famous for its culinary offerings, excellent hotels, and ample shopping opportunities as it is for its red light district (the infamous Reeperbahn, where the Beatles kickstarted their career) and cult football scene. Whether you’re looking to have a pint over a St. Pauli match or spend an afternoon shopping on the Neuer Wall, Hamburg’s multifaceted personality will charm you. Be sure to take in the city’s lush landscape, elegant waterways, and beautiful architecture, and don’t forget to enjoy anAlsterwasser (“Alster Water,” Hamburg’s response to the Radler).
