Out-Law / Your daily need to know
Pinsent Masons has one of the leading international arbitration practices in the energy and infrastructure sectors. We enjoy a world-class reputation in successfully delivering high-value and technically complex cases.
Our team is co-led by Jason Hambury in London and Dean Lewis in Hong Kong. We represent clients on commercial and investment treaty arbitrations all over the world, involving different procedural and substantive laws, issues of public international law, enforcement and treaty rights.
With some 200 dedicated arbitration practitioners based in London, Paris, Singapore, Hong Kong, Dubai, Doha, Johannesburg, as well as Mainland China and Australia, our arbitration expertise has a truly global footprint.
Typically at any one time we are instructed on over 70 international arbitrations, a significant number of which will involve sums in excess of US$100m, and some of which will be very considerably higher.
Our current arbitration portfolio consists of cases comprising some US$10.5bn in dispute involving claims that are high profile and have legal and political significance. We have close links to the major arbitral institutions such as the ICC, LCIA, CIETAC, AAA, DIAC, SIAC, SCC, HKIAC and ICSID. We also have significant experience in conducting UNCITRAL and ad hoc arbitrations.
Our links with the international arbitration community are longstanding. We were on the drafting committee for the England & Wales Arbitration Act 1996 and the DIAC and SIAC Rules. We regularly participate in the pre-eminent research studies. In 2016 we supported the Queen Mary University of London study on dispute resolution in the technology sector. This research was subsequently nominated by Global Arbitration Review for the Best Development of 2016 Award. In 2019 we again partnered with the University on a study into Construction Arbitration.
Our arbitration practitioners are truly diverse and international, many of whom are qualified in more than one legal system and multilingual. They regularly act as advocates and some of them sit as arbitrators. This has allowed us to forge strong relationships with the leading international arbitrators and provide informed advice to our clients on the important issue of arbitrator selection and the composition of the panel.
