Public International Law
4 New Square Chambers is a fast growing presence at the public international law Bar. Members of Chambers regularly act on behalf of, and against, national governments in the UK and abroad in contentious and advisory proceedings, and advise governments, corporate bodies, non-governmental organizations, and individuals on a range of matters including:
- the protection of foreign investment under bilateral investment treaties as well as regional protections such as NAFTA and the Energy Charter
- the interpretation and application of international law in domestic courts and international courts and tribunals
- state and diplomatic immunity
- international environmental law
- the use of force and armed conflict
- the international protections for human rights through international treaties such as the European Convention on Human Rights and the International Covenant on Civil and Political Rights.
Current and recent instructions in the field of public international law include disputes before the International Court of Justice, the ICSID and ICC tribunals, the European Court of Human Rights, the Court of Justice of the Economic Community of West African States, and the domestic courts of the United Kingdom, the Gambia and the Republic of Turkey. Given Chambers’ long-standing strength in international arbitration work, members of chambers are particularly well placed to advise and to represent parties in investor-State disputes.
