On 17 February 2023, Mr Justice Fancourt handed down judgment in Robert David Mackenzie v (1) Rosenblatt Solicitors (2) Rosenblatt Limited  EWHC 331 (Ch).
The case involved a claim for damages for breach of retainer and negligence arising out of a failed claim in conspiracy brought against Mr Mackenzie’s former employer in the AA plc group, in which he sought damages of up to £220m. Mr Mackenzie made allegations of breach of duty and negligence against his former solicitors, including in respect of their alleged failure to advise him that his conspiracy claim had a poor prospect of success, before he incurred, and became exposed to, substantial legal costs.
The judgment is significant, since it provides guidance on how to plead a case in unlawful means conspiracy properly (both factually and ethically) and the duty upon solicitors to advise clients as to the prospect of success of proposed or ongoing litigation.
