International Organisations Law

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.

Legal services in International Organisations Law

Chambers’ IOL practice is divided as follows:

  • Debarment Regimes of Multilateral Development Banks (MDBs) and International Financial Institutions (IFIs): international corruption and bribery, representing companies and individuals accused of fraud, corruption collusion and coercion (together, the Sanctionable Practices) before MDB sanctions regimes as well as global investigations and settlement negotiations.
  • Sanctions Law: advising companies and individuals on all aspects of sanctions law across all regimes, particularly those affecting financial transactions and trade between the US, UK, EU, Russia and Iran. Members of the IOL team regularly represent and advise clients on sectoral sanctions risks relating to prospective commercial transactions, the interaction between UN Security Council resolutions and EU and US law, the EU Blocking Regulation, US secondary sanctions regime, the scope and effect of the Iran nuclear deal (JCPOA) and the post-Brexit statutory framework of the UK sanctions regimes . Members also advise on reporting obligations to the UK’s Office of Financial Sanctions Implementation (OFSI), as well as US, EU and UK delisting applications and civil or criminal penalties arising from sanctions breaches.
  • International Administrative Law: representing international civil servants, class actions of individuals, staff associations and international organisations themselves before international administrative tribunals and other international judicial and quasi-judicial bodies.
  • International Arbitration and ADR: representing parties in commercial arbitrations (including UNCITRAL and LCIA), mediations, conciliations and settlement negotiations with an international dimension, often involving international organisations.
  • International Regulatory and Disciplinary Law: representing both international civil servants and international organisations themselves – with an emphasis on misconduct related to fraud before the disciplinary bodies, committees and appeals panels of international organisations.
  • Immunities of International Organisations and diplomatic immunities: advising on prospects of challenging acts of international organisations before national courts and the applicability of international human rights law to organisations (including domestic litigation before the Court of Appeal and Supreme Court).
  • International Criminal Law and International Humanitarian Law: instructions before the UN International Criminal Tribunal for the former Yugoslavia (ICTY) and in case involving the crime of torture under the UN Convention against Torture.
  • Legal consultancy for international organisations including designing internal justice systems and institutional rules and regulations so that they are compliant with international administrative law.
