EU & Competition LawOver the past 20 years members of Henderson Chambers have been instructed in most of the leading group actions issued in the English courts. Henderson Chambers has been at the forefront of the development of the law and practice in relation to group litigation orders and group actions, as well as representative actions and other collective redress actions.
The group actions that members of Chambers have acted in cover a wide range of different types of claim, including: product liability claims; environmental and pollutions claims; group actions arising out of large accidents and disasters; group actions brought by foreign nationals against UK registered companies; collective competition claims; group actions brought by consumers and under the Consumer Credit Act; data protection actions; group actions in respect of industrial disease litigation; employees claiming wrongful dismissal due to defective technology relied upon by the employer; group actions in respect of historic physical, sexual and financial abuse and group actions arising out of the mis-selling of financial and other products. Members of Chambers have become expert in advising in relation to the obtaining of group litigation orders, the structure and management of group actions, and in relation to the funding of group actions.
