Foley Hoag Attorneys Publish Report on Ghana-Cote d’Ivoire Maritime Boundary Delimitation

Foley Hoag LLP partner Clara Brillembourg and associate Nicholas Renzler have authored “Dispute Concerning Delimitation of the Maritime Boundary Between Ghana and Cȏte d’Ivoire in the Atlantic Ocean,” a new report featured in the authoritative reference guide International Maritime Boundaries. Brillembourg and Renzler were among the Foley Hoag legal team that represented Ghana in the proceedings before the Special Chamber of the International Tribunal for the Law of the Sea (ITLOS) that established the boundary.

This maritime boundary is the first to be delimited by a Special Chamber of ITLOS. The proceedings were also the first maritime delimitation case involving continued hydrocarbon extraction by one of the parties within the area of dispute. Brillembourg and Renzler’s report explores the historical, political, legal, geographic, economic and environmental considerations surrounding the boundary line.

In its ruling, the Special Chamber unanimously agreed with Ghana that the boundary should follow an equidistance line, and that Ghana acted lawfully in its drilling and extractive activities on its side of that line.

Brillembourg and Renzler are both members of the firm’s International Litigation and Arbitration Department. Brillembourg specializes in counseling sovereign States in international disputes with other States, foreign investors and U.S. plaintiffs. She has substantial experience in maritime boundary disputes before the ICJ, UNCLOS Annex VII arbitral tribunals and ITLOS. Renzler’s practice focuses on State-State and investor-State disputes in front of the world's principal dispute resolution bodies, with a particular focus on environmental and public policy issues.
