Kajetan maintains a busy practice in both litigation and arbitration. He has attracted unusually early recognition from the market, receiving a total of 8 rankings in major categories across the Legal 500 and Chambers & Partners within 5 years of call to the Bar. Directory recommendations include “operating at a level far beyond his call”, “an excellent advocate” and “an outstandingly talented junior who is destined for big things.” He was named by The Lawyer magazine on its list of the “Hot 100” lawyers in England in 2024.
His practice focuses particularly on civil fraud, economic torts, general commercial disputes, injunctions, construction and infrastructure, shipping, insurance, and banking and finance. Many of his cases raise complex conflict of laws issues, and he regularly acts in disputes governed partly or entirely by foreign laws (both common law and civil law systems). Geographically, he has particular experience of work concerning the Middle East, India, Ukraine, Russia, Poland, Singapore, China (both mainland and Hong Kong) and offshore financial centres. He often deals with voluminous expert evidence, whether in forensic accounting, engineering, or foreign law.
Kajetan works equally frequently with leaders from these and from other chambers, in the latter case usually at the specific recommendation of Instructing Solicitors. He also has a substantial unled advocacy practice both in the High Court and in arbitration, usually appearing against counsel many years his senior. 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, 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.
Before coming to the Bar, Kajetan ran a small consultancy, working on the application of decision-making games such as chess to thinking processes in education, business and rehabilitation of prisoners.
Kajetan specialises in commercial fraud disputes, for which he is recommended by the Legal 500. His cases range from single-forum cases to heavyweight multi-jurisdictional litigation involving simultaneous proceedings in London and multiple foreign jurisdictions onshore and offshore. His practice is roughly balanced between acting for claimants and defendants, both as sole counsel and as junior to leading Silks in the field.
He has experience of all major English law causes of action relevant in fraud claims, including deceit, breach of fiduciary duty, conspiracy, breach of trust, dishonest assistance, unlawful interference, procurement of breach of contract, bribery, and intimidation; statutory fraud claims under the Insolvency Act and FSMA; as well as fraud claims governed by foreign systems of law. On the procedural side, he advises on and provides advocacy in relation to all procedures relevant in fraud claims, such as freezing orders, service out, disclosure applications under the Norwich Pharmacal and Bankers Trust jurisdictions, contempt of court 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.
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  EWHC 363 (Comm) (a LIBOR-related fraud claim and a significant case in the law of misrepresentation), to Jacobs J on GDS v NCR  EWHC 1119 (Comm) (a claim raising all major economic torts), and to Bryan J on Lakatamia Shipping Co Ltd v Su & Ors  EWHC 1907 (Comm) (unlawful means conspiracy).
He often works on cases which attract media coverage.
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”. Although no longer new to the rankings, he remains one of the most junior barristers in the current editions, reinforcing that description.
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. The 2023 edition of the Legal 500 described him as having “Fantastic attention to detail and insight, and yet still able to clearly see the bigger picture.”
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).
Kajetan enjoys working in large teams, and quickly integrates into the team.
Kajetan has substantial experience of document- and expert-heavy disputes concerning engineering projects and infrastructure, both in arbitration and in litigation. He was recommended as a “Rising Star” in the Construction category in the 2023 edition of 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.” Ranked at only three years into practice, Kajetan was the joint most junior barrister recommended in that category.
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. He has practised in the area since commencing independent practice in 2019, having spent a significant proportion of pupillage on assisting with shipping matters such as The “ELIN”  EWHC  (Comm) (the current authority establishing that the statement on a Bill of Lading that the carrier would not be liable for loss of or damage to deck cargo “howsoever arising” is apt to exclude liability for negligence and/or unseaworthiness) and The “Arctic”  EWCA Civ 1161 (an arbitration appeal in which the Court of Appeal determined the status of the obligation to keep a vessel in class), an LMAA arbitration arising out of long-term detention of a vessel in Venezuela, an LMAA arbitration in respect of a failure to redeliver a barge concerning the availability and quantum of restitutionary damages for conversion, and various other matters.
Kajetan advises on and acts in insurance matters, for example in respect of coverage disputes, fraud, as well as subrogated claims. In the latter category, he has particular experience of claims for damage to or destruction of property by fire, but has also dealt with matters arising out of other perils such as flood, building subsidence, and voltage damage to electrical equipment.
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. He is also regularly instructed by banks, particularly in claims arising out of commercial financing such as business lending, guarantees, sales ledger financing, etc. He regularly publishes articles in the area.
In addition to commercial disputes, Kajetan has built up significant experience of advising and acting for businesses on high-risk disputes with consumers requiring delicate strategy and difficult judgement calls. He is very rarely if ever instructed in “regular” consumer disputes such as about quality of goods or services, but he is often called upon by businesses facing consumer claims giving rise to risk of regulatory action, carrying adverse media interest, or having potential wider repercussions by establishing a precedent.
He regularly advises and acts for clients operating in regulated sectors, such as banks and gambling operators, and has advised and acted for businesses facing consumer claims arising out of COVID-19 since the early days of the pandemic. He also has experience of assisting businesses facing large cumulative exposure to waves of low-value consumer claims in respect of the same subject matter coordinated on social media or similar channels, from early strategic advice, through advising throughout the disputes, drafting pleadings and/or applications, to advocacy.
His work in this specialist niche has been recognised by the Legal 500, where he is the most junior barrister recommended in the Consumer Law category for the second year running.
Kajetan has a niche specialist practice in gambling disputes, advising and acting for large gambling operators as well as their customers. He has experience of the whole gamut of such disputes, from contractual (bet outcome disputes, issues of cheating/dishonest bets, withholding of winnings pending completion of integrity investigations) through tortious (problem gambling, self-exclusion) to the interface between findings of regulatory authorities and private law actions between the customer and the bookmaker. He has handled matters ranging from high-value claims about a single bet, through disputes with VIP customers, to disputes about the correct settlement of a market involving hundreds of individual claims (whether coordinated or not).
Kajetan has particular experience in bet outcome disputes in respect of events without an obvious mathematical outcome or official result of a governing body, where the gambling operator has made an evaluative judgement, for example as to the correct result or the appropriate time to close betting.
Complementing his practice in gambling disputes is Kajetan’s practice concerning racehorses, in which area he has been acting for and against several well-known owners, trainers, and auction houses.
Kajetan has experience of IT and telecoms disputes, e.g. concerning hardware, software, and internet projects, including design defects, bugs, delays, fitness for purpose, etc.
Kajetan has experience of a broad range 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.
