Expertise

Sonia has a lively commercial litigation practice, and has been instructed in numerous commercial disputes, including arbitral proceedings, raising issues including:

  • Allegations of fraud in a commercial context, including employee or director fraud.
  • Deceit, breach of fiduciary duty, breach of trust, knowing receipt, dishonest assistance, conspiracy, conversion and receipt of bribes.
  • The construction and validity of contracts, including penalty, liquidated damage, evergreen and insolvency clauses.
  • Construction of joint venture agreements and of letters of credit.
  • Undue influence and capacity.
  • Directors’ duties, partnership disputes and shareholder disputes.

Notable Commercial Dispute Resolution cases

Acting for the respondent in a c.£4m ad-hoc arbitration concerning the alleged breach of a commission contract and construction of “evergreen” clauses. Sonia (leading Will Clerk) successfully applied for security for costs.

Representing several respondent parties in a c.£25m unfair prejudice petition in which the petitioners sought an injunction preventing allegedly sham disciplinary hearings against them from taking place (leading Luka Krsljanin, reported at [2020] EWHC 23 Ch).

Representing a defendant property investor against allegations of breach of confidence and conspiracy to injure, arising out of a property transaction.

Sonia has very significant experience in insurance and reinsurance, and has been listed in Chambers UK and the Legal 500 as a leading junior in this area for many years. She is a Tier 1 Leading Junior in the Legal 500, which describes her as “fearsomely bright…her knowledge of black letter insurance law is second to none. Sonia is my go-to person in all insurance matters when I have a difficult insurance query.”

Sonia regularly advises and litigates on:

  • Disputes arising out of a wide range of covers (professional indemnity, business interruption, public liability, EL, litigation protection, property, art, and consumer).
  • Construction and coverage disputes.
  • Subrogation and assignment issues.
  • Non-disclosure (in both the commercial and consumer context).
  • Joint names insurance.
  • Contribution between insurers.
  • Brokers’ negligence
  • EU regulatory matters.
  • Fraudulent claims.

She is particularly well-known in the market for her expertise in employer’s liability and public liability and related covers such as product, professional indemnity and contractor’s all risks. She represented MMI from first instance all the way through to the Supreme Court in the EL Trigger Litigation [2012] UKSC 14, and appeared in the leading case on policy triggers in public liability insurance, Bolton Metropolitan MBC v Municipal Mutual Insurance Ltd [2006] 1 WLR 1492.

In the field of first party cover she is well-versed in the issues arising in connection with business interruption, fidelity, art and cultural property and personal lines insurance for high net worth individuals. She is also sought after for her expertise in life and health insurance (see further below).

Notable Insurance & Reinsurance cases

Advising on insurance issues in connection with the restoration of an historic London building of national significance.

Advising on policy coverage over a residential heritage property following a fire which caused c.£3.5m of damage.

Advising on insurance and repairing obligations under a long lease of property held by a Government department.

Advising on the construction of contamination exclusions in PL policies, both in connection with Covid-19 and in other contexts.

Sonia’s work on life, income protection and permanent health insurance is an important part of her insurance practice, with Chambers UK noting that she “is a junior of choice for many major insurers” in this highly specialised niche market. She is regularly instructed on large value and complex claims, often against leading counsel.

In addition to relatively straightforward income protection/PHI cases where the extent of disability is disputed, Sonia has substantial experience of the more factually and legally complex disputes which arise under this class of insurance. She regularly advises on group policies, privity of contract between insurer and employee, and limitation (an issue of particular complexity given that the obligation is usually to pay benefit monthly).

On the life/critical illness side, she has dealt with fraudulent claims, suicides (including inquests), murder of one life insured by another, disputes between insolvent policyholders and their trustees in bankruptcy, policies written under trust and cases raising issues of joint/composite insurance.

Sonia has also, very unusually, represented insurers in a judicial review of the Financial Ombudsman Service for (among other matters) making determinations which wrongfully had the effect of overriding FOS’s financial limit.

Notable Life & Health cases

Representing insurers in the Court of Appeal in an appeal concerning construction of disclosure obligations under a policy of income protection insurance (led by Caroline Harrison QC, reported at [2019] EWCA Civ 261).

Advising on a high value and sensitive life insurance case involving financial coercion, in which one spouse had taken out multiple policies over the life of the other, and later murdered them (unled).

Sonia has been listed as a leading junior for professional negligence every year since 2010. The current edition of Chambers UK describes her as “absolutely excellent – good on complicated matters and always available and helpful”.

Over the years she has litigated professional negligence actions of all kinds including:

  • Claims involving property damage and construction professionals (structural engineers, architects, building control inspectors, quantity surveyors, project administrators).
  • Claims against brokers and financial advisors, requiring her insurance/commercial expertise.
  • Claims with an underlying chancery/commercial flavour, where allegations of fraud have been made or when professional indemnity cover is disputed.
  • Numerous valuer claims, testing the boundaries of contributory negligence by lenders (prime and otherwise), and advising on the complex issues which arise when fraudulent conveyancing is suspected, or the loan in question has been assigned and/or securitised.
  • Claims in which the “loss of a chance of a better outcome” approach was challenged.
  • Claims by and against for lawyers in many contexts, particularly where fraud or coverage issues are in play.

Notable Professional Negligence cases

Representing the defendant solicitor in a claim arising out of the drafting of a joint venture agreement for a commercial property transaction, raising an undecided point of law on whether “loss of a chance” applies when a third party gives evidence on what they would have done in hypothetical situation (reported at [2019] EWHC 1326 Ch).

Representing the defendant designer/manufacturer in a £4m claim arising from the design, manufacture and supply of 35,000 faulty valves for use in domestic oil fired boilers.

Sonia has been listed as a leading junior for property damage every year since Chambers UK introduced the category. She has been ranked as a Band 1 junior for several years. Chambers UK describes her as having “a brain the size of a small country…knows property damage law like the back of her hand.”

Over the years she has litigated damage claims of all kinds including:

  • Large commercial fires arising from defective design, products and working methods, from failed fire suppression measures and from use of equipment or appliances known to be defective.
  • Domestic fires caused by a wide range of appliances including golf cart batteries, fridges, TVs and tumble dryers.
  • Fires resulting from arson or carelessly discarded smoking materials.
  • Indoor floods caused by air conditioning units, LTHW systems and defective pipework.
  • Outdoor floods involving culverts, drains, bunds and highways, and floods caused by changes to the topography of an area during building development.
  • Nuisances arising from spread of fire, ignis suusand escape of dangerous substances.
  • Nuisances involving loss of amenity, business interruption and financial loss.
  • Nuisances with a real property element, such as interference with easements, trespass, and claims where one or both parties’ interest in land is via adverse possession.
  • Subsidence and landslips.
  • Coverage disputes under CAR, public liability, PI and other policies.
  • Cross-over claims involving liability of professionals, especially in the construction field.

Sonia is currently instructed in numerous high value and high profile damage cases. She almost always acts unled due to her expertise, seniority and market profile, and usually leads others.

Notable Property Damage cases

Successfully resisting a strike-out application on justiciability grounds in a complex flood claim (reported at [2021] EWHC 543, leading Jack Harris).

Acting as lead counsel in a claim arising from the destruction of historic seafront building by fire (leading Will Clerk).

Sole counsel in a c.£25m warehouse fire alleged to have been caused by a piece of light plant which ignited.

Sole counsel in a c.£3.5m claim arising from flood damage to a prime central London residence.

Significant Cases

Anchor Hanover Group v The Environment Agency and 4 others [2021] EWHC 543 (TCC)

A multi-party action in the TCC arising out of a flood in Bicester in 2013, resulting in significant damage to a block of sheltered accommodation. The cause was a blockage in a culvert created as part of large scale diversionary works. Multiple defendants were involved, including several parties with hydraulic modelling and design responsibility, the riparian owner of the culvert, and the Environment Agency as statutory consultee. Sonia successfully defended a strike-out application by the Environment Agency against her client, put on the basis that the EA did not owe any duty of care on the facts. Instructed by Pinsent Masons LLP, leading Jack Harris.

Newton Equine Services Limited v Jane Sewell and others [2020] EWHC 3874

A debt claim for unpaid stud fees, with a counterclaim for the death of a valuable dressage horse in the stud’s care. Sonia represented the stud farm. Liability was admitted and the principal issue was valuation by reference to the mare’s past performance and her likely ability to have produced future champions had she lived. Issues included (a) whether on a true construction of an order of a QB Master, S had permission to rely on two veterinary experts in different sub-disciplines; (b) whether 89 questions asked by S were impermissible cross-examination and otherwise in the scope of Part 35; (c) whether there should be an unless order against S if her valuation expert refused to disclose comparables relied on. Instructed by Kennedys Law LLP, leading Will Clerk.

In the Matter of R-Squared Holdco Limited (Company No. 1078321) and In the Matter of the Companies Act 2006 (Petitioners: Brown) [2020] EWHC 23(Ch)

The Petitioners alleged that disciplinary proceedings against them by one of the respondent companies were a sham intended to engineer the loss of their shareholding. They sought an injunction restraining any of the Respondents from carrying out the disciplinaries, or procuring others to carry them out. Sonia represented the Second to Fourth Respondent companies. Instructed by Gateley plc, leading Luka Krsljanin.

Moda International Brands Limited v Gateley plc [2019] EWHC 1326 (Ch)

A professional negligence action arising out of the drafting of a joint venture agreement in connection with a commercial property transaction. The claim raised the previously undecided question of whether the Court should adopt a “percentage chance” approach to the assessment of damages when the counterparty had (unusually) given evidence at trial as to what he would have done in a hypothetical situation where there had been no negligence. Instructed by BLM.

Friends Life v Miley [2019] EWCA Civ 261

An appeal against the decision below on policy construction grounds. The appeal considered the scope of the insured’s obligation to disclose information about other income, and the extent to which that obligation was modified or limited by a declaration which stated that the insured “believed” that the information was provided was true. Instructed direct by Friends Life, led by Caroline Harrison QC and leading Luka Krsljanin.

R (on the Application of Aviva Life and Pensions (UK) Limited) v Financial Ombudsman Service [2017] EWHC 352 (Admin)

A very unusual application for judicial review by an insurer of the Financial Ombudsman Service’s decision to reinstate a policy of life insurance, where this would inevitably result in a payment to the insured of more than the FOS jurisdictional limit. Instructed direct by Aviva, led by Robert Moxon Browne QC.

Miley v Friends Life Limited [2017] EWHC 2415 (QB)

A £1.5 million income protection/permanent health claim raising issues of capacity to carry out employment and fraud (in that the insured had been seen on surveillance footage engaging in activities significantly in excess of what he had declared himself able to do). Sonia acted for insurers. Instructed direct by Friends Life, led by Caroline Harrison QC and leading Luka Krsljanin.

Miley v Friends Life Limited [2017] EWHC 1583 (QB)

A life insurance case in which the life insured had moved to the Mumbai office of his employer, and ceased to be insured under the UK group life insurance policy. He had been involved in a fatal accident while in Mumbai and his widow claimed under the life policy. The issues included what, on a true construction, was meant by “permanently employed” outside the UK when there was a possibility, albeit not guaranteed, of a future return. Sonia successfully defended the claim on behalf of L&G, appearing against leading counsel. Instructed by Eversheds Sutherland International LLP.

Co-Star v Red Leads and others [2014] EWHC 1262 (Ch)

Sonia acted for the Claimant in an application in which she successfully obtained a costs order against a party who had objected to being joined as a defendant; the party argued that there was no jurisdiction to make a costs order because he had not been a party until the moment when he was joined and could not be made liable for costs incurred prior to that moment. Instructed by Gateley plc.

Bate v Aviva [2013] EWHC 1687 (Comm)

A consumer insurance claim arising out of a fire, which raised FSMA issues concerning possible routes of recovery for damages for late payment of damages (the case predated the Insurance Act 2015); insurers alleged misrepresentation, non-disclosure on inception and breach of condition precedent. Sonia acted for the claimant policyholder. Instructed by Neumans LLP, led by Neil Moody QC.

Smyth v St Andrews Insurance [2012] EWHC 2511 (QB)

An insurance claim in which the Defendant insurer alleged that the fire was caused by arson on the part of the policyholder’s partner. Sonia acted for insurers. Instructed by Kennedys LLP.

BAI (Run off) Limited (In Scheme of Arrangement) v Durham (and 5 other actions) [2012] UKSC 14

Better known as the “EL Trigger Litigation” – this is the leading case on policy triggers in employers’ liability insurance and also provides an important clarification of the law of construction of contracts, factual matrix and commercial purpose. It was the first case to consider the Employers’ Liability (Compulsory Insurance) Act 1969 at Supreme Court level. Instructed by Watmores, led by Howard Palmer QC.

Municipal Mutual Insurance Company Ltd v Zurich Insurance Company and 10 others (and 5 other actions) [2010] EWCA Civ 1096

Dennard v PricewaterhouseCoopers LLP [2010] EWHC 812 (Ch)

Municipal Mutual Insurance Company Ltd v Zurich Insurance Company and 10 others (and 5 other actions) [2008] EWHC 2692

Instructed by Watmores, led by Howard Palmer QC.

Bolton Metropolitan MBC v Municipal Mutual Insurance Company Ltd and another [2006] 1 WLR 1492; [2006] 1 LRIR 15 (CoA, QBD)

Bright v Barnsley District General Hospital NHS Trust [2005] Lloyds Rep Medical 449
