At a recent Frontier Economics Litigation event, the President of the Competition Appeal Tribunal, The Honourable Mrs Justice Bacon, warned that advocate economists, or economists who ignore obvious analytical points adverse to their client, were not helpful to the Tribunal and self-defeating for the expert.

The Competition Appeal Tribunal has published a Practice Direction on expert evidence. The Practice Direction sets out the principles applicable to expert evidence in the Tribunal, including general principles applicable to the evidence of any expert, as well as certain specific principles applicable to economic evidence.
