Kajetan is described by independent legal directories as “one of the most able juniors at the Bar” and “a future leading counsel”, who is “operating at a level far beyond his call”. He was named by The Lawyer magazine on its list of the “Hot 100” lawyers in England in 2024.

Amongst other comments, directories have emphasised Kajetan’s oral advocacy (“a brilliant advocate”, “an excellent advocate”, “what looks complex, he makes sound simple”), written advocacy (“excellent research and drafting skills”), court strategy (“very strategic in his thinking”, “understands how things are likely to play out in court”), analytical ability (“stunningly bright”, “supremely intelligent”, “able to analyse complex factual situations and give strategic advice”, “brilliant ability to absorb large amounts of material and quickly produce clear advice”), and his focus on the client’s practical position (“able to clearly see the bigger picture”, “responsive, great with clients and extremely pragmatic”, “written work […] is clear, succinct and constitutes actionable advice for busy practitioners”).

Several of the cases which he has argued as sole counsel have been cited in major practitioners’ textbooks, including (amongst others) Chitty on Contracts, Lewison on the Interpretation of Contracts, Cartwright on Misrepresentation, Mistake and Non-Disclosure, Benjamin’s Sale of Goods, and Clerk & Lindsell on Torts, as well as widely covered in legal updates such as law firm newsletters and articles. Almost invariably though not exclusively, he appears against counsel many years his senior and increasingly often against KCs.

Kajetan is recommended for civil fraud work by both Chambers & Partners and the Legal 500. He is regularly instructed on complex civil fraud disputes governed by varying legal frameworks, from English common law and equitable claims, through statutory causes of action (such as under insolvency, company or financial services legislation), to claims governed by various foreign laws. Many of those are global disputes involving simultaneous proceedings in multiple onshore and offshore jurisdictions.

On the procedural side, he advises on and provides advocacy in relation to all procedures relevant in fraud claims, such as worldwide freezing orders, contempt of court, disclosure applications under the Norwich Pharmacal and Bankers Trust jurisdictions, service, recognition, enforcement, etc., as well as matters where fraud or allegations of fraud affect the process of the court itself rather than being the subject of the dispute.

Featured Civil Fraud cases

  • NMC v Shetty. Acting for Dr B.R. Shetty defending claims for USD 5 billion+ in the courts of the Abu Dhabi Global Market, arising out of the collapse of the NMC Group. The dispute has already resulted in a number of complex hearings, including preliminary issues of ADGM insolvency law (NMC Healthcare Ltd & Ors v Shetty & Ors [2024] ADGMCFI 0007 and Shetty v NMC Healthcare Ltd & Ors [2024] ADGMCA 0001); heavily-fought case management applications concerning concurrency (Abu Dhabi Commercial Bank PJSC v Manghat [2023] ADGMCFI 0021 and Abu Dhabi Commercial Bank PJSC v Manghat [2023] ADGMCFI 0025), discretionary stay in favour of proceedings in another jurisdiction (NMC Healthcare Ltd & Ors v Shetty & Ors [2023] ADGMCFI 0024), and joinder (Abu Dhabi Commercial Bank PJSC v Manghat [2024] ADGMCFI 0010); applications concerning confidentiality (NMC v DIB [2023] ADGMCFI 0006); and others.

  • Eletson Corporation v Levona Holdings Ltd BVIHCM2024/0111. Acting for the defendants in the British Virgin Islands Commercial Court in a successful 3½-day application to discharge a worldwide freezing order described in the judgment as “complex and voluminous matter [which] entails greater length, in terms of everything, for this return date than for many plenary trials, even in this BVI Commercial Court.” The WFO was discharged (without being re-granted) for breaches of duties of full and frank disclosure and fair presentation.
  • Madison Pacific Trust Ltd v Groza & Naumenko [2024] EWHC 267 (Comm). Acting for the beneficial owners of a major grain terminal in Ukraine in a complex application to discharge a worldwide freezing order.

  • During the Hilary term 2021 (January to March), Kajetan worked as a full-time Judicial Assistant in the Commercial Court, assisting judges on several complex fraud matters. In particular, he was a judicial assistant to Cockerill J on Leeds v Barclays [2021] EWHC 363 (Comm) (a LIBOR-related fraud claim and a significant case in the law of misrepresentation), to Jacobs J on GDS v NCR [2021] EWHC 1119 (Comm) (a claim raising all major economic torts), and to Bryan J on Lakatamia v Su [2021] EWHC 1907 (Comm) (unlawful means conspiracy).

Kajetan is recommended for Commercial Dispute Resolution by both Chambers & Partners and the Legal 500. When he was first ranked in this area, he was the most junior barrister recommended for commercial litigation in Chambers & Partners, alongside counsel many years his senior – reflecting the nature of his general commercial (non-fraud) practice described in the directory as “operating at a level far beyond his call”.

He acts extensively in general commercial disputes, both as a junior and as sole counsel. He has worked for a full range of commercial clients: corporations, SMEs, joint ventures, public authorities, company directors, and UHNW individuals. He frequently advises on strategy and procedure, and is noted by clients for his focus on the interplay between the legal analysis and the commercial aims of the litigation.

During the Hilary term 2021 (January to March), Kajetan worked as a full-time Judicial Assistant in the Commercial Court and the Financial List (to Cockerill J, Jacobs J, and Bryan J).

Following the close of pleadings, PD Teesport obtained summary judgment on the force majeure defences raised by P&O (based on the impact of Covid-19 and Brexit), resulting in immediate judgment for 99% of the value of the claim.

Kajetan regularly advises upon and represents parties in relation to issues of civil procedure, whether governed by black letter law, high-level principles, or the Court’s discretion. He has experience of all areas of case management relevant to heavy commercial litigation, including amongst others contested amendments, disclosure, joinders, stays, full and partial summary determination, etc., and a particular expertise in issues relating to open justice and confidentiality of court proceedings (hearings in private, access to court records, party anonymity, disclosure of sensitive material, collateral use, redactions, privilege, etc.). He has acted in a number of heavily-fought multi-day procedural applications.

Kajetan has experience of document- and expert-heavy disputes concerning engineering projects and infrastructure, both in arbitration and in litigation. He was previously recommended as a “Rising Star” in the Construction category in the Legal 500, which described him as having “‘Fantastic attention to detail and insight, and yet still able to clearly see the bigger picture. He has a natural aptitude for complex construction cases. An outstandingly talented junior who is destined for big things.” At the time, Kajetan was the joint most junior barrister recommended in that category.

Featured Construction projects, infrastructure, and engineering cases

  • A USD 800m ICC arbitration between the main contractor and the lead designer in respect of a major infrastructure project in the Middle East.
  • TCC litigation between engineering consultants and the main contractor in connection with design services and building information modelling (BIM) for a major infrastructure project on an offshore military base.
  • A complex £8m adjudication regarding the construction of one of the largest schools in the country (the issues included the appropriateness of advice on the form of procurement, duties to warn, management of value engineering, experts’ conflicts of interest, and the extent to which important facts can be inferred rather than proved by direct evidence).

Kajetan is ranked as a Rising Star in shipping disputes by the current edition of the Legal 500. He has experience of a variety of matters concerning the international trade and transport of goods, including sale of goods disputes, delays, misdelivery, damage to cargo, discharge of cargo against Letters of Indemnity, detention and arrest, and exclusions of liability.

Featured Shipping, commodities, and international trade cases

  • Acting for owners in two LMAA arbitrations in respect of discharge of cargo against letters of indemnity.
  • Concurrent LMAA arbitrations concerning a delay caused by repairs to a vessel’s ballast water treatment system.
  • An USD 80m+ LCIA arbitration concerning sale contracts for delivery of refrigerated commercial propane.

Kajetan spent a part of his pupillage with a leading insurance senior junior. He advises on and acts in a range of insurance matters, for example in respect of coverage disputes, fraud, as well as subrogated claims.

 

Featured Insurance and subrogated claims cases

  • International Medical Technology Investments S.A.R.L. v. Consortium 9744 at Lloyd’s. EUR 70m+ Commercial Court dispute between a private equity house and a Lloyds syndicate in respect of warranty & indemnity cover for a share purchase transaction.
  • Advising insurers and insureds alike on coverage, notifications, repudiating cover for fraud, etc. under different types of policies, including in particular (but not exclusively) issues naturally arising in connection with Kajetan’s civil fraud practice, such as defence cover under D&O policies.
  • Advising a Middle Eastern insurer on differences between English, DIFC, and ADGM insurance law in relation to fair presentation of risk.
  • A variety of subrogated claims in relation to property damage, including by fire, flood, and building subsidence.
  • Pearson v Northern Powergrid (Northeast) Plc [2022] 4 WLUK 184. A subrogated claim against an electric power distribution network in respect of extensive damage to electronics in a “smart home” caused by a surge in voltage. The Court accepted that strict liability for defective consumer products under the Consumer Protection Act 1987 could be applied to a surge in voltage on the basis that the relevant “product” for the purposes of the statute is not electricity as such, but domestic electricity of specific voltage and frequency. Thus by transforming high-voltage electricity to domestic voltage alongside its network, the network operator becomes a “producer” for the purposes of the Consumer Protection Act 1987 and can in principle be strictly liable for any damage caused by surges. Extremely unusually for a County Court decision, it has been cited in major textbooks: Clerk & Lindsell on Torts and Charlesworth & Percy on Negligence.

Kajetan handles a variety of banking and financial services matters, both contractual and regulatory. He has experience of the Financial Services and Markets Act 2000, the Financial Services Act 2012, and the Regulated Activities Order, in particular of civil enforcement claims by the FCA.

  • Advising a group of institutional investors in connection with proposed large-scale securities litigation under s. 90A FSMA.

  • Acting for a bank in relation to alleged misreporting of suspicious transactions.
  • Acting for a bank in a successful summary judgment application in respect of refinanced debt of a construction company.
  • Acting for a bank against directors of a company in a claim on personal guarantees of loans to the company.

Kajetan has experience of professional negligence claims (both on the claimant and defendant side), including in particular claims against lawyers and financial professionals, but also construction professionals such as architects, engineers, valuers and surveyors.

Featured Professional Negligence cases

  • Advising a firm of solicitors in connection with wide-ranging claims of professional negligence and breach of fiduciary duty in respect of conduct of litigation.

  • Acting for an architect in a multi-defendant claim alleging (as against the architect) defects in the technical aspects of the design of a residential home.

Kajetan has significant experience of advising and acting for businesses on high-risk disputes with consumers requiring delicate strategy and difficult judgement calls, for example where the dispute concerns a unique one-off contract, gives rise to a risk of a group action, raises the risk of regulatory action, attracts adverse media interest, or involves exposure to waves of low-value consumer claims in respect of the same subject matter coordinated on social media or similar channels.

Featured High-stakes consumer disputes cases

  • Longley v PPB Entertainment Ltd [2022] EWHC 977 (QB); [2022] LLR 436; [2022] CLY 532: successfully defending the bookmaker Paddy Power in a £286,000 claim in respect of a horseracing bet, raising issues of mistake and the correct approach to the unfair term provisions of the Consumer Rights Act 2015.

  • Advising a major online betting exchange in respect of hundreds of coordinated small County Court claims relating to the same betting market.
  • Advising and acting for a holiday park operator in successfully defending multiple claims related to park closures caused by the COVID-19 pandemic, where thousands of potential claimants appeared to coordinate via Facebook.
