Matthew has a broad commercial practice, but with a particular interest in and focus on disputes involving technology (in all industrial, commercial and consumer contexts). 

Matthew is regarded as one of the most sought-after silks at the bar for technology disputes, with a focus on IT, IP, telecoms and related disputes (including software copyright, licensing, cyber risk, cloud, blockchain and fintech, AI and the internet). This is demonstrated in the directories, where comments include “Technically brilliant and great with clients”; “Matthew’s depth of knowledge, both relating to the law and also on the technical side, is immense. It feels like he has everything in hand” “An absolute star and a pleasure to work with. He provides excellent client service, is always on top of the facts and is possessed of brilliant analytical and technical skills” (Chambers & Partners 2024 – IT).

Matthew was shortlisted for Technology, Data and Crypto Silk of the Year in the Legal 500 bar awards in 2023 and for Information Technology/Intellectual Property Silk of the Year in the Chambers & Partners bar awards in 2024. He was one of only two barristers ranked as a Global Market Leader in Artificial Intelligence by in the Chambers & Partners Global inaugural listing.

His practice areas are:

  • Technology and Telecoms
  • Fintech & Blockchain
  • Intellectual Property (tech related)
  • Aviation
  • General Commercial Litigation & Arbitration

He is co-editor of Hervey & Lavy, The Law of Artificial Intelligence (Sweet & Maxwell, 2020; 2nd edition 2024), and he is a Trustee of the Society for Computers and Law. He is also on the Nominet DRS panel as an Expert for resolving domain name disputes, and is listed in the Blockchain Lawyers’ Forum Arbitrator List.

Matthew acts and advises on a wide range of technology and telecoms-related disputes. He is regularly instructed on behalf of providers, purchasers and users of networks, computer systems, internet and cloud services and software across a variety of industry sectors.  In addition to disputes involving mainstream business systems and services of all sizes, Matthew has acted and advised in relation to highly specialised applications such as broadcasting platforms, radio-telecommunication networks, core banking systems, military technology, safety critical software, and industrial control systems (SCADA/PCL). Disputes in which he has been instructed include those arising out of project failures and delays, IP licensing, copyright infringement, breach of confidence, outsourcing agreements, data protection, digital media and digital rights management. He also has expertise and has advised in relation to cyber liability and the insurance of cyber risks, cryptocurrencies, blockchain technologies and ICOs. His clients regularly include tier-one IT suppliers, telecoms giants, and software and equipment suppliers with global reach.

Matthew is a leading expert in the law of AI and machine learning systems. He is co-editor of The Law of Artificial Intelligence (Sweet & Maxwell, 2020; 2nd edition 2024). His particular focus within the AI field is on liability risks arising out of the development, deployment, training and use of AI and machine learning systems.

Prior to coming to the bar, Matthew worked as a software developer, system administrator and technical writer. Between 1997 and 2002 he gained extensive software development experience (programming in Java, C, C++, Perl, SQL and VB), provided technical support to an 800-node computer network and wrote two books on systems administration. He was responsible for the design and implementation of a business critical 15-000 user bespoke software application commercially commissioned by a leading university. As a result of this experience, Matthew brings to technology disputes an excellent and deep seated understanding of software, networks, IT systems and development approaches, and first-hand appreciation of the realities of project definition and delivery.  He is able to discuss details of a case with experts and clients at the deepest technical level; he can “translate” technical concepts for the benefit of a legal team, arbitral tribunal or the court.
