Jon-David Giacomelli was one of the three founding partners of Cambridge LLP and the Chair of the Cross-Border and Business Litigation Groups. His practice has encompassed a wide range of complex cross-border litigation and alternative dispute resolution, with an emphasis on private international law, conflict of laws, jurisdictional disputes, enforcement of foreign orders, shareholders’ rights and injunctive relief. Jon-David has represented clients from around the world and is recognized in Canada, the U.S. and abroad as a leading practitioner in the area of cross-border litigation and arbitration.

Mr. Giacomelli has been a frequent speaker and writer on issues related to business litigation, private international law and in particular, cross-border litigation, dispute resolution and conflict of laws. He has spoken and lectured widely at city, provincial, state, national and specialty bar associations in Canada, the United States, South American and Europe.
