Insurance & Reinsurance

As set out above, Christopher is ranked as a leading junior in this sector by Legal500, which describes him as follows: “Highly intelligent, keeps a sense of humour and perspective at all times, knowledgeable and experienced beyond his years”. His recent practice in this area includes:

  • Acting (with David Railton QC, Michael Crane QC and James Cutress QC) for a reinsurer in a complex arbitration brought against it by a construction company’s captive insurer. The proceedings raised issues under the law of New York relating to the extent to which a reinsurer is bound to follow settlements, aggregation of claims, the extent to which faulty workmanship and defective construction work counts as an accident or property damage, as well as the incorporation, scope, and applicability of exclusions.
  • Acting (with Stuart Ritchie QC) for an individual in a coverage dispute relating to two D & O policies. The dispute turned on points relating to an insured’s obligations to assist an insurer, the advancement of defence costs, and the grounds on which an insurer can deny coverage, and arose against the background of civil and criminal proceedings being brought against the individual by their former employer.
  • Acting (with Derrick Dale QC) for a large group of claimants in a substantial solicitor’s negligence claim in a dispute with the insured’s indemnity insurers regarding the application of the aggregation provisions in the Solicitors’ Minimum Terms. The dispute took place against the background of repeated errors by the insured solicitors, and potential fraud, in the context of the sale of a large number of off-plan leasehold properties.
  • Christopher has substantial experience acting as sole counsel in insurance matters. By way of example he has:
    • Advised the SRA on a coverage dispute with a solicitor’s liability insurers, in which the SRA seeks to advance a claim based on rights acquired by way of subrogation, and the insurer says that the claim was not covered on the basis it sought repayment of fees;

    • Advised Lloyd’s underwriters on the proper interpretation of an aggregation clause, and its application to a number of claims brought against valuers.

Professional Negligence

  • Christopher has extensive experience of bringing and defending professional proceedings against providers of legal services, including:
    • Acting (with Derrick Dale QC) for a barrister in a claim said to be worth £20m regarding the provision of negligent advice, which is alleged to have led to the loss of the opportunity to pursue a supposedly valuable mis-selling claim against a leading UK bank. The dispute turns on issues regarding the likelihood of litigation being pursued and resulting in substantial sums being recovered from the bank.
    • Appearing (with Derrick Dale QC) for a large number of purchasers of off-plan properties in proceedings against the solicitors who acted for them in relation to the purchases. The aggregate value of the claims was over £10m, and the proceedings raised issues relating to (among other things) the duties of a purchaser’s solicitors in such transactions, and causation.
    • Acting (with Patricia Robertson QC) for one of the successful defendants in Ridgewood Properties Group Ltd v Kilpatrick Stockton LLP, a large dispute between a firm of solicitors and their former clients, raising issues relating to advice on repudiatory breach, affirmation, advice from counsel, and causation. The Claimants discontinued their claim after the largest part of it was struck out as an abuse of process.
    • Advising a firm of solicitors on whether reliance on counsel’s advice gave them a defence to a claim based on the negligent conduct and settlement of litigation.
  • He has also appeared in a number of matters concerning professional negligence in the financial sector. For example he has:
    • Acted (with James Cutress QC) for a leading firm of financial advisers in two sets of proceedings against former consultants, raising issues relating to the COB rules, the provision of financial advice, and the recovery of sums paid out to settle claims.
    • Appeared, as sole counsel in the High Court, for a prominent UK bank in a case concerning allegations that it negligently advised a wealthy client to invest in certain funds. The claim also raises issues relating to the extent to which a bank owes duties to its customer at common law when calculating any offer of redress made to the customer.

Civil Fraud

  • Appearing (with Brian Doctor QC) for a Paraguayan company in proceedings against individuals said to be responsible for a $40m fraud against it. The claimant successfully obtained freezing and search orders against the defendants, the latter in a novel form.

  • Acting (as sole counsel) for a supplier of electrical components in a matter concerning suspected fraud by a senior employee and a former employee, and a company connected to them which supplied services to the supplier.
  • Christopher has experience of disputes arising out of cybercrime and cyberfraud. For example:
    • As set out above, he has acted:
      • for a charity in a dispute concerning whether it was entitled to an indemnity under a computer fraud provision in an insurance policy, after it was the victim of fraud carried out via e-mail; and
      • for a bank in proceedings brought by a customer after a third party obtained the customer’s login details through a keylogger, and used them to make a series of payments out of the customer’s account.
    • He has, as sole counsel, advised a company on obtaining disclosure of the identity of account holders from paying and receiving banks in circumstances where payments which were meant to be to the company were instead made to third parties, who then dispersed the monies they received, as a result of fraud carried out via e-mail.
  • As sole counsel, Christopher successfully defended a merchant payment services provider at trial against a claim alleging that funds which should have been remitted to the claimant were not, and where the merchant payment services provider refused to remit the funds as it suspected they were being transferred as part of a £1.3m mandate fraud.

Conflict of Laws and Jurisdiction

  • Appearing (with Derrick Dale QC) in Coward v Ambrosiadou, a dispute between two Monaco-domiciled individuals raising issues at the jurisdiction stage as to whether proceedings between them ought to be heard in England or Cyprus, and whether an alleged agreement between them would be governed by English or Cypriot law. The dispute arises against the background of dozens of pieces of litigation involving the individuals and entities connected to them, taking place in Monaco, Greece, Cyprus and the BVI.
  • Acting (with Stuart Ritchie QC) for a Russian individual in proceedings against another Russian individual, seeking remuneration due under a contract for services, and declaratory relief in relation to a number of other agreements. This included acting for the claimant in an application to serve proceedings out of the jurisdiction, raising issues concerning the applicable law, the “necessary or proper party” gateway for granting permission to serve out of the jurisdiction, and when a substantial risk of injustice in another forum may lead to England being the proper forum. Christopher also appeared as sole counsel in a subsequent application relating to effecting service, once permission to serve out had been obtained.
  • Appearing (with Richard Coleman QC) in Standard Chartered Bank (Hong Kong) Ltd v Independent Power Tanzania Ltd (both in the Court of Appeal and at first instance), which concerned a challenge by a Tanzanian company to the existence and exercise of the Commercial Court’s jurisdiction over claims brought against it in England by a bank situated in Hong Kong, following proceedings in New York and Tanzania. Christopher also appeared as sole counsel in the Court of Appeal against a leading silk in an interim hearing.
  • Advising an English company on jurisdiction and choice of law issues arising from a dispute with the Scottish office of a French company. This dispute raised complex issues regarding the Brussels Regulations Recast, and the application of Article 25 (relating to express jurisdiction agreements) to a ‘battle of the forms’ situation where each party sent the other its standard terms, containing differing provisions regarding jurisdiction (and indeed choice of law).
  • Advising a Maltese company on the enforceability of judgments obtained in the Maltese Courts in England under the Brussels Regulation.

The proceedings raised issues concerning who had a beneficial interest in the aircraft, and who had control of it.
