Insurance and reinsurance litigation

Within: Insurance and reinsurance litigation

With an impressive reputation in insurance litigation, BLM's London office can hold its own with any firm’; it has ‘a very strong team with market-leading expertise in coverage disputes, notably in the fields of commercial property insurance and liability insurance’. This has recently been enhanced by the arrival of professional negligence expert Ross Baker, who specialises in professional indemnity and D&O liability insurance, from Womble Bond Dickinson (UK) LLP. ‘A modern litigator who gets excellent results’, Baker is ‘an insurance and reinsurance coverage expert with superb people skills’. The strong team is headed by John O’Shea, who has ‘great experience of coverage litigation and major subrogated claims’, as well as ‘a very acute understanding of the law', and is 'admirably cool under pressure'. Another noteworthy member of the team is Mark Aitken, ‘an insurance litigator with particular strength in factually complex coverage disputes such as major fire claims’, whose ‘rigorous pursuit of every line of enquiry has secured an enviable series of victories in the High Court’. The team acts for major insurers in important reported cases and ‘achieves excellent results through its meticulous enquiries and clear, rigorous litigation strategies’. A recent example is its advice to Network Rail Infrastructure on a variety of property-related disputes including environmental issues, boundary disputes, engineering issues and other liability claims relevant to land ownership and the rail industry, notably the Court of Appeal case of Williams and Waistell v Network Rail Infrastructure Limited.
