Having had some limited involvement in the Pertussis (Whooping Cough) vaccination litigation in the early 1980s (acting first for the Secretary of State for Health and Committee on Safety in Medicines and then for various medical experts summoned as witnesses), he witnessed the collapse of the first phase of that litigation because of the inadequacies of the test case approach adopted. As a result, in the Opren litigation in which he again acted for the Government, he was instrumental in developing the approach to group litigation with lead cases and costs sharing orders which has since become the model for GLOs. After the Government’s successful defence of that litigation, he has become involved in a wide range of group actions, principally in the field of product liability (in particular, tobacco, HIV haemophiliac litigation, CJD human growth litigation and BSE litigation) but also in a range of other fields including group actions against solicitors (Investors Compensation Scheme litigation, Paragon Finance litigation and most recently The Accident Group litigation), tax schemes (Container Leasing, Film Finance and Technology Investment Schemes in particular), and disaster litigation (Buncefield oil explosion at Hatfield by way of example).

He specialises in the cross-examination of witnesses, both factual and technical, in areas varying from specialist scientific subjects such as pharmaceuticals, chemicals and materials and engineering issues, to financial, accountancy and taxation issues.
A key element of his work for defendants in litigation is the analysis of causation issues. This includes issues of epidemiology, statistical probability and causation in fact and was a central element of his preparation work for the human growth hormone and Variant CJD litigation. He spent many months learning about the relative risk of cancer from different activities and problems of causation of cancer when acting for Gallaher, one of the principal Defendants in the tobacco litigation. This work also involves issues of scope of duty and remoteness of damage, particularly in relation to future economic loss.
He is accustomed to dealing with cases involving very large numbers of documents and is familiar with most document management technology systems as well as the use of spreadsheets and databases.
Many of his cases involve careful analysis of accounts, taxation issues, the detection of fraud and exaggerated claims, and the calculation of economic loss.
