A native of The Netherlands, Pieter was in private practice in Amsterdam before serving for nearly three years as a staff lawyer in the Registry of the International Court of Justice (ICJ), the principal judicial organ of the United Nations seated in The Hague. Pieter has also advised a variety of corporate clients in cross-border commercial transactions and financings. He regularly counsels clients in the drafting of arbitration and other clauses for international contracts.
