Wessen Jazrawi
OVERVIEW
Wessen specialises in large-scale competition damages litigation, on behalf of both corporate entities and consumers in opt-out claims. She is passionate about access to justice, and also plays a key role in our human rights & environmental practice.
Expertise
Prior to joining Hausfeld, Wessen worked at the Financial Services Authority and at Orrick, Herrington & Sutcliffe where she worked on a number of claims before the Competition Appeal Tribunal. This included the first follow-on action to have reached trial in the UK, Enron Coal Services Limited v. English Welsh & Scottish Railway.
At Hausfeld, she has conducted litigation before the Competition Appeal Tribunal, High Court and the Court of Appeal, and has extensive experience on both traditional competition damages claims and collective actions. Examples of the former include some of the most well-known competition cases of recent years such as the MasterCard / Visa interchange fee litigation and the Marine Hose cartel. In the collective sphere, she is acting for Christine Riefa Class Representative Ltd in proposed collective proceedings against Apple and Amazon. She also acted for the proposed class representative, the Consumers’ Association (Which?), in an abuse of dominance claim against Qualcomm on behalf of a class of UK consumers. Finally, she acted for Privacy International in its intervention before the Competition Appeal Tribunal in relation to the Meta / Giphy merger, and is acting for them in the Amazon/iRobot matter before the European Commission.
Working towards a diverse, equitable and inclusive work force is paramount to Wessen who is an active member of Hausfeld's Racial Justice group.
Clients
Because of the nature of her practice, she represents people and corporates, both on an individual or group basis. Notable representations at Hausfeld include acting on behalf of 10+ corporate groups against MasterCard / VISA, for Christine Riefa Class Representative Ltd against Apple and Amazon, and for Privacy International with respect to the Meta/Giphy merger and the ongoing Amazon/iRobot acquisition.
