Public International Law

Public and Private International Law

We have a large group of members practising in several areas of public international law. Members at Matrix have excellent reputations, acting in cases before the International Court of Justice, the International Tribunal for the Law of the Sea, the Permanent Court of Arbitration, the International Criminal Court, and the criminal courts and tribunals established for the former Yugoslavia, Rwanda, Sierra Leone, Lebanon, Cambodia and East Timor. To find out more about our arbitration experience, please see our dedicated page.

Specialist areas

Our members cover all areas, including the more specialist fields such as: international organisations and courts and tribunals; diplomatic and other immunities; trade and investment; land and maritime boundary disputes; natural resources; the environment, including climate change; and human rights.

The work includes advisory and litigation. Members are especially experienced in advising on the work of international organisations – at the regional and global levels – and representing states before international courts and tribunals.
