Our International Organisations Law barristers (the IOL Team) have unrivalled experience in the laws, systems and frameworks of international organisations, having been instructed in cases involving more than 30 international institutions worldwide. Such organisations enjoy a number of privileges and immunities and, as a result, have created internal justice systems that are not bound by domestic jurisdictions.

Most international organisations are created by multilateral treaties concluded between sovereign states and they are, therefore, products of public international law. All cases relating to international organisations require expert lawyers with an understanding of the complex workings of each institution, whether they deal with corruption, regulation, employment rights, whistleblowing or policy making in the context of advocacy, litigation, investigations and advisory work.
