Expertise & Experience

In this section

International law is extremely relevant to any cross-border activity and therefore to any public or private sector entity involved in trans-national trade, commerce and investment. In a shrinking world, global and regional cooperation increases the need for an understanding of developments in international law and the ever-expanding impact of international and extra-territorial regulation.

For over 40 years our dedicated team has advised corporations, sovereign States and international organisations on the complex and far-reaching effects of public and private international law and, increasingly, on international regulation and enforcement, including:

  • Economic sanctions
  • Export controls
  • Business and human rights, including corporate responsibility issues
  • Anti-money laundering, anti-corruption and anti-terrorism regulation
  • Bilateral investment treaties and investment protection
  • International environmental law and regulation 
  • International trade law, including the WTO regime
  • Risk assessments for international projects and investments. 

Traditional public international law is extremely important in relationships involving a State or international organisation and we advise on:

  • Treaties and their interpretation
  • Territorial issues, boundaries and jurisdiction
  • Recognition of states, state succession
  • State responsibility 
  • Human rights and international humanitarian law 
  • International environmental law and regulation
  • Law of the sea 
  • State and diplomatic immunity 
  • Privileges and immunities of international organisations 
  • Proceedings before specially constituted claims tribunals 
  • Proceedings before other international courts and tribunals, including the International Court of Justice.
