Gary Walkling - RPC

Within: Insurance and reinsurance litigation

‘A pre-eminent insurance litigation firm’, RPC has a reputation for contentious insurance work in the financial lines, international property and power generation and energy sectors, areas in which it receives increasing numbers of instructions. The team is also investing in new sectors, having recently hired Naomi Vary, who specialises in trade credit and political risk insurance, from Sedgwick, Detert, Moran and Arnold LLP. Karen Morrish also joined from Sedgwick, Detert, Moran and Arnold LLP, while Toby Higginson and Toby Savage were promoted to partner. The team, headed by Simon Laird, also includes energy insurance market expert Gary Walkling, and is known for its ‘excellent personnel and very capable and effective resources' and for 'providing a quality service’. The practice also has significant capability in the cyber risks field and has developed a cyber incident response service called ReSecure. The team acts for some of the major insurers, London market companies and global composites, including AIG, Liberty, AXA CS, XL Catlin and Aviva. Recent highlights include Simon Goldring applying for a declaration, on behalf of AXA CS, that the English court does not have jurisdiction over XL's claim for double insurance against it, and Leigh Williams acting for WR Berkley Insurance and Lancashire Insurance Company in the high-profile case of Single Buoy Moorings Inc v Aspen Insurance UK & Ors. The latter represents the largest single asset insurance claim that has ever been litigated in the UK and one of the largest contested insurance claims brought in any jurisdiction.

Legal Developments by:

  • Cancelling insurance: insolvency and downgrade clauses

    One of the most common concerns for both parties to an insurance contract (including reinsurance) is that the other party might become insolvent and unable to perform its obligations under the contract. Both insurer and insured will therefore wish to have the right to cancel the insurance mid-term in the event of the other party’s insolvency, or a change in its financial circumstances that makes its insolvency a more likely prospect in the near future.
