RPC's 'well-established and dedicated department is a first port of call for corporate and insurer clients' and has 'a growing presence in the health and safety arena' thanks to the 'brilliant leadership' of practice co-heads Gavin Reese and Nick McMahon; clients praise Reese as 'clever and tenacious' and single out McMahon as 'highly experienced and easy to work with'. Reese's recent work includes acting for a lift installation company in a HSE and police investigation following the death of an employee who sustained crush injuries and representing United Grab Hire and its director in a HSE prosecution following a fatal accident. McMahon acted for a construction company in an asbestos-related issue and represented a senior hospital manager who was investigated following a patient's suicide. XL Catlin and Faraday are also clients.

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.
