Christopher Mann

Business

Business litigation is at the heart of Christopher’s practice.

He deals with disputes about commercial disputes of most kinds except shipping contracts. One of his advantages is that he has knowledge and expertise in a number of areas of law, in particular banking, company, civil fraud, conflict of laws and real property and brings this multi-disciplinary experience to the cases in which he is involved.

He also has a domestic and international arbitration practice.

Christopher has appeared in a range of construction and engineering disputes over the years and is skilled in digesting technical and expert evidence. He now principally appears/advises in technically – complex sale of goods/supply of services disputes (including adjudications).

Examples of recent cases include representation of a foreign bank in respect of a number of property sales alleged to have been the subject of misrepresentation; and a claim in the Chancery Division for specific performance of a contract to transfer shares/damages.
