Investment Treaty Arbitration

Allen & Overy has one of the world’s leading International Arbitration practices and a long track record of achieving successful outcomes for our clients in high-value, complex disputes.

We have represented our clients in more than 50 investment treaty claims and have extensive experience of handling arbitration proceedings under the ICSID Convention and the UNCITRAL Arbitration Rules. We regularly represent both sovereign States and claimant investors in these complex disputes.

In addition, we advise states in relation to the negotiation of, and accession to, investment treaties and other public international law instruments, such as free trade agreements. We also advise clients in relation to the structuring, and restructuring, of their overseas investments to secure investment treaty protection.

Ours is a truly global practice, with leading investment treaty practitioners in a number of locations around the world, including London, Paris, Hong Kong, Dubai and Singapore.

We are recognised as being innovators in this field and as having particular expertise in relation to disputes arising under the Energy Charter Treaty (ECT). Our experience includes bringing the very first arbitration under the ECT, as well as the first collective claim under the ECT.
