David’s practice includes business agreements and general commercial disputes, civil fraud, banking, company and partnership matters (including insolvency), professional negligence, and claims against trustees and other fiduciaries. He is equally at home in the Chancery Division and Commercial Court, has experience as an advocate in the Court of Appeal, and has appeared in domestic and international arbitrations. Much of his work has an international aspect, be it jurisdiction challenges or worldwide freezing orders before the English courts, or appearing and advising in offshore jurisdictions such as Singapore, Hong Kong, Gibraltar, the Cayman Islands and Jersey. In 2005 David successfully represented Roy Ranson, the former Managing Director and Appointed Actuary of Equitable Life, at the trial of Equitable Life v Ernst & Young, Bowley & Ors, the £3.3bn High Court action brought by the Society against its former auditors and board. Other substantial matters in which he has since been involved include the Berezovsky joint venture proceedings, a shareholder dispute concerning Bumi Plc, the long-running Masri v Consolidated Contractors litigation, claims in the administration of Lehman Brothers, several large commercial frauds (including JSC BTA Bank v Ablyazov, Jennington v Assaubayev, Cadogan Petroleum plc v Tolley and Marlwood v Kozeny) and the proceedings arising out of the Buncefield oil terminal explosion.
