Public International Law

Latham & Watkins’ dedicated team of globally recognized public international law lawyers regularly acts for both States and private entities in contentious and non-contentious matters.

Why Latham

The firm’s PIL lawyers work on matters related to every continent and region of the world. They contribute insightful and seasoned PIL advice to Latham’s work in project finance, energy, infrastructure, telecommunications and international disputes.

The PIL team has provided market-leading representation in the following areas:
  • Concessions, including for straddling resources
  • Economic sanctions
  • Human rights
  • International environmental law

Latham’s PIL practice also advises clients on the complex and nuanced application of public international law in domestic courts.
