Public and Private International Law


Matrix International has a large group of lawyers practising in several areas of international law. Our public international law team has an excellent reputation, acting in cases before the International Court of Justice, the International Criminal Court, the International Tribunal for the Law of the Sea 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.

Our private international law group has expertise in advising on issues in commercial contractual disputes involving jurisdiction or choice of law. We have acted for individuals, governments and corporations in claims involving human rights, employment, insurance and consumer disputes.

Specialist areas

Our specialist areas include rules governing international trade, land and maritime boundary disputes, natural resources, environmental protection, climate change and international human rights. We have worked for international organisations and our members have represented states in the ICJ and ICC. Professor Philippe Sands QC and Kate Cook were involved in the Australia v Japan litigation in the ICJ, concerning Japan’s whaling activities in the Pacific Ocean. Professor Sands QC and Professor Zachary Douglas QC also acted in Georgia v Russia before the ICJ and in the recent maritime and territorial boundary dispute Croatia v Slovenia. Four Matrix members have been involved in the cases involving Al-Gaddafi and Al-Senussi: Professor James Crawford AC SC, Professor Philippe Sands QC, Ben Emmerson QC and Michelle Butler.

Professor Sands QC also acted for Croatia before the ICJ in Croatia v Serbia, a case concerning the Genocide Convention. Four other Matrix members were involved in that case: Kate Cook, Edward Craven, Helen Law and Blinne Ní Ghrálaigh.


See former member Professor James Crawford AC SC discuss his role in the Whaling case between Australia and Japan in the International Court of Justice in his Matrix International interview.

In her interview, Michelle Butler discusses the types of disputes that arise from post-conflict situations and some of the cases she has worked on.
