Where
Event Type
From ‘expert-led’ proceedings to a ‘cartel of misbehaviour’: the evolving treatment of, and expectations for, expert evidence by the Competition Appeal Tribunal
Expert evidence plays a central role in many proceedings before the Competition Appeal Tribunal, where complex questions of economics, valuation, accounting, technology and market behaviour can be critical to the issues the Tribunal has to determine.
This session will examine the particular approach taken to expert evidence in the CAT, including the Tribunal’s expectations of experts, the preparation and presentation of expert evidence, interaction between opposing experts and the practical issues that can arise during proceedings.
It will also consider and discuss the evolving treatment of expert evidence, from at one point requiring a more “expert-led” process to complaints about too much expert involvement and the new dedicated Practice Direction on Expert Evidence.
The session will address how the Tribunal’s approach is developing and what those acting as experts, or instructing them, need to know.
Networking
After the meeting we will retire to the Gray’s Inn Bar.
