European Competition Litigation Circle
7 May 2026
to 8 May 2026
Grande Real Villa Itália Hotel & Spa, Lisbon, Portugal
The European Competition Law Litigation Circle is an exclusive, invitation only event. It will feature up to 40 handpicked European practitioners with a focus on Competition Litigation. Returning for it's second year, the event is curated by our Advisory Board Sarina Williams of Linklaters, Miguel Sousa Ferro of Sousa Ferro & Associados, Carolin Marx of Hogan Lovells, Marc Barennes of Geradin Partners, and Michele Carpagnano of Dentons.
This exclusive invitation only event, involves facilitated discussions across 1 and a half days of content.
We have been working with the advisory board to devise and curate the invite list and areas of discussion. Designed to be interactive and as inclusive as possible, there are no set-piece presentations or panel sessions with the focus being on open discussion.
The event will run in two broad formats: horseshoe & interactive roundtables, whereby we are expecting all attendees to be involved throughout. Our Advisory Board will each lead on the sessions to get the conversation amongst all attendees started.
Given the format this is very much fluid, and we are keen to take suggestions from attendees up until the event itself as to what you would like to have covered.
This Circle is kindly supported by:

Roundtable 2 – Key Considerations in Damages Estimation - Hosted by RBB Economics
- Beyond damage estimation, what additional value can economists bring to the litigation process ?
- Before damage estimation, how can economists effectively ground their analysis in market realities without stepping into issues that have already been decided in the liability phase?
- On damages estimation, what happens when one side presents detailed economic work, and the other side does not? How should courts weigh these asymmetries in evidence?
- Still on damages, is there room to move away from the quasi-presumptive overcharge rates (e.g., 5% or 10%) seen in the Trucks litigation?
- Looking ahead, how might big data and AI-driven tools influence economic analysis in litigation?
