Wessen plays a key role in both our competition and human rights & environmental practice areas. Providing access to justice for individuals and businesses – regardless of the practice area - lies at the cornerstone of her practice.


At Hausfeld, she has worked on some of the most well-known competition cases of recent years, including the MasterCard / Visa interchange fee litigation and the Marine Hose cartel.

Prior to joining Hausfeld, Wessen acted in two cases before the Competition Appeal Tribunal, including the first follow-on action to have reached trial in the UK, Enron Coal Services Limited v. English Welsh & Scottish Railway.


Because of the nature of her practice, she represents people and corporates, both on an individual or group basis. For example, she advised a group of international retailers in proceedings relating to multilateral interchange fees and represented a large group of multinational companies in a private damages action following the global Marine Hose cartel. 



Wessen Jazrawi is a member of the team that stands out for praise and recognition. In an ongoing case, Wessen has once again shown to me her enormous commitment to her clients and the vindication of their rights. Throughout Wessen has ensured that my clients understand the process and that they are thereby able to play a part in forming the case and the arguments and the way in which the case is framed.
