Cameron’s practice is split between domestic and international courts and tribunals.

He also advises on such proceedings in other common law jurisdictions, including Australia and New Zealand. Elsewhere, he has appeared in high-stakes proceedings before the Permanent Court of Arbitration, the International Tribunal for the Law of the Sea, and the International Court of Justice.
In the arbitral arena, Cameron has developed considerable expertise in investment treaty arbitration, appearing in 16 separate proceedings, whether during the initial arbitration, in relation to post-award remedies, or in relation to arbitration-related applications in the English courts.
