Tom is a highly versatile lawyer whose practice straddles public law, competition/regulatory law and commercial law, and who has achieved recognition as a leading practitioner in eleven different practice areas. Tom is noted for his innovative legal problem solving - drawing upon the many aspects of his practice - and his excellent advocacy.

In the public law field, Tom’s work has a strong emphasis on: commercial JR, where Tom has acted in a number of the leading cases (Camelot, Eisai), particularly pharmaceutical litigation and sanctions work; civil liberties, national security (Binyam Mohammed, Kamoka) and data and privacy work (Privacy International/LQDN); and on environmental cases. Tom is a noted expert on the control of secondary legislation and on proportionality and fundamental rights challenges (FACT, Lumsdon), having obtained the first ever declaration of incompatibility by consent (Blood No.2) and the last EOC declaration to disapply primary legislation for incompatibility with EU law (Hughes).

In the competition and regulatory field, Tom has appeared in many of the leading competition law damages cases (Provimi, Devenish), acting regularly for both Claimants (e.g. Peugeot in the bearings litigation) and Defendants (e.g. Goldman Sachs in the FX litigation), as well as in standalone cases (e.g. the ongoing Genius sports betting data litigation). Tom has particular expertise in the application of the competition rules in the context of sport, acting for both the regulated (clubs, players etc) and the regulators/leagues (RFU, Premier League, ECB). Tom has also acted for and against many of the key sectoral regulators (Ofgem, Ofcom, Oftwat etc) in energy and telecommunications disputes, professional discipline matters and the like.

Tom’s commercial work has an emphasis on group litigation (most recently various Dieselgate disputes), conflicts issues (Tom has led in many leading cases domestically and in the CJEU ranging from Grovit v Turner, AMT Futures and most recently MV Prestige), economic torts (particularly market-facing disputes), privacy (e.g. ENRC v Gerrard) and restitution litigation (e.g. the ALFs litigation).

A unifying feature of all of Tom’s work is his noted expertise in EU law work in all hues, public, regulatory or commercial. Before Brexit, Tom appeared in many CJEU/GC cases, in areas ranging from sanctions (NITC), to competition (FIFA/UEFA, Topps Europe), trademarks (Philips), pharmaceutical work (Teva), social security to conflicts, data protection/privacy (Fish Legal, Privacy International/LQDN) and to Brexit itself (Wightman). Tom appeared in the last two Article 267 TFEU references from the UK (DfCNI and MV Prestige).

Competition

Tom is a highly experienced and sought-after competition lawyer. He has an extensive practice ranging from pure commercial/competition work, through EU regulatory (with its blend of public and competition law), commercial EU (such as financial services and conflicts) to diverse “pure public” EU work in areas such as pharmaceutical regulation, data protection and privacy, free movement cases, EU social security and EU fundamental rights and discrimination.

He is a member of the CAT Users Group.

Tom was the Legal 500’s EU and Competition Silk of the Year in 2019 and is ranked Band 1 and 2 for Competition law in Legal 500 and Chambers & Partners respectively (“He is a leader in this area and really knows his stuff. He was one of the first barristers to really see the potential of group and class actions”).

“Pure” competition damages: Tom has acted in a large number of the most prominent competition damages claims since the Vitamins litigation in the mid-00s (in which Tom acted for the Defendants, Aventis, in Provimi, Devenish and other reported cases). Since then, Tom has acted for Claimants in Air Cargo (Emerald), RoRo, Interchange (multiple parties and firms) and Peugeot Bearings, among others. He is also working for Defendants in the various vitamin cases (Aventis), LCDs (Toshiba in Nokia) on Power Cables (Nexans) and is instructed in the FX litigation (Goldman Sachs).

Blended competition claims and competition consumer law: Tom is at the forefront of modern cases involving competition law claims/counter-claims/defences blended with other private law claims. This is a particular characteristic of the two strands of the ongoing Genius litigation (which also involve database and unlawful means claims). Tom’s particular interest in consumer law and data protection means he is well placed to advise and act on such issues where they interface (as they increasingly do, particularly in the digital space) with competition law, especially in abuse of dominance claims.

CPOs and “book built” claims: Tom has written extensively, advised, and acted in relation to CPOs, including in the Mobility Scooters application (the first under the Act), including both follow on and standalone claims. Tom was a member of the CAT Working Party on collective proceedings. Tom has acted in claims involving large multi-party “book built” claims (e.g. Interchange, Trucks, FX, Air Cargo).

Competition & Sport: Tom is an acknowledged expert on the interface between competition law, common law, restraint of trade, and sport, in relation to issues such as salary caps (RFU, Scarlets, F1), financial fair play (RFU, competition law arbitrator in the QPR arbitration), player nationality requirements (ECB, RFU, F1), fixture and league sanctioning/breakaway competitions (Premier League) and regulation by dominant sports bodies (ECB, RFU). Tom is also well versed in the competition (and other) events relating to “Listed Events” (having acted in the GC/CJEU in the FIFA/UEFA cases) as well as the competition law issues in relating to sports broadcasting (e.g. Virgin complaint, Genius litigation).

Regulatory EU/competition work: Tom has undertaken work in all the main fields of sectoral regulation based on EU frameworks on both pure competition points and sectoral regulatory issues (such as systems access, price control etc), notably telecoms (both for and against Ofcom, including currently acting against Ofcom in the first exercise of its competition investigation powers), gas and electricity (for and against Ofgem and the NIAUR) and water (against Ofwat).

EU Law

Tom is a highly experienced and sought-after EU lawyer. He has an extensive practice ranging from EU regulatory (with its blend of public and competition law), commercial EU (such as financial services and conflicts) to diverse “pure public” EU work in areas such as pharmaceutical regulation, data protection and privacy, free movement cases, EU social security and EU fundamental rights and discrimination.

Tom is an acknowledged expert on both Brexit (in particular the operation of EUWA 2018, EUFRA 2020 and the TCA) and state liability claims.

Tom was the Legal 500’s EU and Competition Silk of the Year in 2019 and is ranked in Band 1 for EU Law (“Tom is pre-eminent in the field, entrusted by clients and plainly highly respected by the tribunals before whom he appears”) by both Legal 500 and Chambers & Partners; and

Conflicts/Brussels Regulation: Tom’s damages work in multi-jurisdictional cartels frequently raises conflicts issues (jurisdiction, applicable law) and associated problems of limitation, exclusive jurisdiction, arbitration and claims characterisation. His conflicts expertise dates back to successfully arguing, as a junior, the seminal Grovit case in the CJEU and the Provimi case in Commercial court. Notable recent cases include the AMT Futures litigation in the Supreme Court and the MV Prestige case before the CJEU Grand Chamber argued in January 2022 (the last ever reference from an English Court), which raises fundamental issues about the interface with arbitration.

Regulatory EU/competition work: Tom has undertaken work in all the main fields of sectoral regulation based on EU frameworks on both pure competition points and sectoral regulatory issues (such as systems access, price control etc), notably telecoms (both for and against Ofcom, including currently acting against Ofcom in the first exercise of its competition investigation powers), gas and electricity (for and against Ofgem and the NIAUR) and water (against Ofwat).

State liability: Tom has acted on both sides of many EU state liability claims, including recently for a claimant class of persons affected by mistransposition of an EU Directive, and for the MIB in the Colley litigation (heard by the CA in January 2022). Such cases require a mix of public law expertise (is a breach ‘manifest and grave’?) and commercial litigation know-how (causation, quantum, market modelling) and have strong similarities with competition law “follow on” claims.

Brexit: Tom is one of the acknowledged experts on the UK’s Brexit arrangements, including all aspects of EUWA 2018 and EUFRA 2020 and the Withdrawal Agreement and TCA. Tom acted for the Public Law Project in the Miller2 litigation and for the UK in CJEU GC hearing in Wightman. He frequently gives presentations on these topics, has advised extensively on them, and has been brought into litigation to advise specifically on these issues.

EU Fundamental Rights and Treaty rights cases: Tom has been involved in some of the most prominent recent cases involving EU Fundamental Rights and EU Treaty rights issues of recent years, including Lumsdon in the Supreme Court (the leading authority on EU proportionality), FACT (proportionality and free movement of goods in relation to the Ivory Act), Hughes (Pensions Act disapplied as incompatible with EU fundamental age discrimination rights), TfL (EU free movement and proportionality) and the Privacy International Litigation (s.94 Telecommunications Act inconsistent with EU privacy law).

Sanctions

Tom has undertaken a broad array of sanctions work, advisory and litigated, in relation to both the EU sanctions regime and purely domestic measures. Tom’s EU sanction work before the GC/CJEU has concentrated principally on Iranian sanctions, acting for individuals/companies (Golparvar, NITC, Bank Saderat), but Tom has also worked on the EU Russian Crimean sanctions (Rosneft).

Domestically, pre-Brexit Tom worked extensively on Al Qaeda and terrorism related sanctions, particularly against the LIFG (Kamoka). Post-Brexit, Tom has advised both governmental and private individuals on the new UK (EU inspired) sanctions regime.
