Matthew has a broad commercial practice, but with a particular interest in and focus on disputes involving technology (in all industrial and commercial contexts). In addition to litigation and arbitration (institutional and ad hoc), Matthew advises in relation to dispute avoidance and in non-contentious commercial contexts. He is on the Lord Chief Justice’s advisory group on Artificial Intelligence and a Trustee of the Society for Computers and Law.

His core practice areas are:

  • Technology and Telecoms
  • Intellectual Property
  • Aviation
  • Commercial Litigation & Arbitration

Matthew is recommended in Chambers & Partners and the Legal 500. Comments have included:

  • exceptionally talented
  • exceptional technical understanding
  • a real help on very difficult software and hardware cases
  • A profound understanding of the technical complexities of software

He was featured as one of 10 “Stars at the Bar” in the December 2013 issue of Legal Week, was nominated for Intellectual Property/Information Technology Junior of the Year at the Chambers & Partners Bar Awards 2014 and 2019, and won that award in 2016.

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.

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.

Matthew was one of the experts involved in the EU Commission-funded E-Crime Project, and is currently on the Nominet and ADNDRC Domain Name Dispute Resolution Panels. He speaks regularly on the legal implications of leading edge technologies such as blockchain, IoT and AI. He was one of the authors of the Legal statement on cryptoassets and smart contracts issued by the TawTech Delivery Panel UK Jurisdiction Taskforce.
