International Arbitration & Dispute Resolution




Mark Beeley is “the standout performer: a highly skilled advocate who is a match for any heavyweight silk in a hearing, but also sees the wider commercial context. He is able to fix the strategy and deliver it, giving clients the confidence that the man at the front really understands and cares about their case.” – Legal 500 UK 2021

Mark acts as advocate and counsel in international arbitrations (both commercial and investor-state) and in litigation in the English and DIFC courts. He has particularly deep experience in energy disputes, but also regularly acts in construction, technology, insurance, shareholder and white-collar/civil fraud matters (including advising on sanctions and export controls), as part of a broader commercial practice.

Mark has acted in arbitrations under the ICSID, LCIA, UNCITRAL, ICC, HKIAC, SIAC, LMAA, DIAC, AAA and other arbitration rules in disputes seated around the globe concerning multiple governing laws and is recognised in the leading directories for arbitration and natural resources disputes. In addition, he sits as arbitrator (including both as chairman and sole arbitrator). He previously practiced in Dubai as a Registered Foreign Lawyer and maintains a practice as advocate (and solicitor) in both the English and DIFC Courts (along with supervising cross-border litigation in multiple jurisdictions). Mark has been recognised as a foreign expert in disputes in both the UAE and India by Chambers.  He has been consistently ranked by Chambers for arbitration, as well being recognised in Legal 500 for both arbitration and commercial litigation.

He has a particular interest in energy sector disputes, including those in the upstream and LNG areas (per Chambers & Partners UK 2018 he knows  “oil and gas inside out” and is recognised in Who’s Who Legal for Energy, Chambers UK for Energy & Natural Resource Disputes and Legal 500 for Oil & Gas), but has dealt with matters across the industry, running the gamut from seismic acquisition agreements through to IP disputes involving refined products, carbon trading agreements and the construction of renewable projects. He currently leads the AIPN Model Form Revision sub-committee focusing on the dispute resolution aspects of the model form JOA.

Beyond energy, Mark has acted in the infrastructure/construction, technology, insurance, crypto-currency, fintech, pharmaceutical, telecoms, insurance and finance sectors (amongst others) and also advises extensively (both in the advisory context and in leading investigations/claims) in relation to white-collar/fraud matters, including money laundering, bribery, sanction and export control issues.

Originally called to the English Bar and now practicing as a solicitor-advocate, Mark frequently publishes and speaks on arbitration and energy matters, including on questions of sovereign immunity, res judicata, arbitration procedure, the award of interest and other questions on damages. He features in two categories of Who’s Who Legal, Arbitration and Energy 2020.  Mark serves as a member of the ICC UK Arbitration & ADR Committee and also leads Orrick’s London Office.
