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 knowledgeable and a good litigator.
