Cameron is a leading barrister practicing in public international law and international commercial and investment treaty arbitration. Described in the directories as “a true superstar in the making”, who can “process complex issues at lightning speed”, he is ranked as a leading junior in both Chambers & Partners and Legal 500 for public international law and international arbitration, and has featured regularly as a Future Leader in Who’s Who Legal.
Cameron’s practice is split between domestic and international courts and tribunals. In England, he is most often to be found in the Commercial Court, where he has developed a market-leading practice on state immunity and enforcement matters that also takes him to the Court of Appeal and Supreme Court. 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.
Cameron is regularly instructed directly by states, state organs, corporations and international organisations. He is comfortable working alone or as part of a team.
