David's practice is in commercial disputes, particularly in the fields of banking and finance, commercial fraud, insurance and reinsurance, professional negligence, and technological and industrial disputes. He appears mainly in the High Court in London, but a significant part of his work is in international arbitration or in the courts of offshore jurisdictions.
Most of his cases have an international element, and he is frequently involved in advising on or arguing issues of conflicts of jurisdiction or choice of law. He regularly works with overseas lawyers.

David's professional negligence practice is focussed on lawyers, accountants, actuaries and brokers.

Before studying law, David was employed for 18 months in the research and development centre of ICL Mainframe Systems (now part of Fujitsu) developing software for the automated design of computer logic and memory components. He was awarded the SB Marsh Scholarship by ICL and also a university sponsorship while taking his mathematics degree. He maintains a close and keen interest in computers and information technology.

He has given a paper to the Society of Computers and Law on "Time and Delay in IT projects".
Many of David's cases involve complex technical, electronic or industrial processes. For example, David has acted:

for a power station operator in a dispute under a long-term gas purchase agreement Esso Exploration v Electricity Supply Board  1 All ER (Comm) 926.
