One of her most significant contributions was leading Ghana’s legal team in the maritime boundary dispute with Côte d’Ivoire at the International Tribunal for the Law of the Sea in Hamburg. The case arose after major oil discoveries in Ghana’s Jubilee and TEN fields. Côte d’Ivoire challenged Ghana’s jurisdiction over these areas, but under her guidance, Ghana argued successfully that it had long exercised sovereignty and that the neighboring claims were untimely.
The tribunal ruled in Ghana’s favor on September 23, 2017, securing the valuable oil and gas resources for the country. This victory preserved billions of dollars in potential revenue, supported ongoing petroleum production exceeding 100,000 barrels per day from the Jubilee Field, and protected reserves in the TEN Field. The outcome strengthened Ghana’s energy sector, contributed to economic growth, and demonstrated the power of peaceful, rule-based international dispute resolution. Many observers view this as a landmark defense of Ghana’s maritime heritage and a boost to national development.
Her appointment as the second female Attorney General marked a milestone for gender representation in Ghana’s top legal offices. She has also served on bodies such as the Ghana @50 Commission of Enquiry and the board of the Volta River Authority. Her selection for the International Chamber of Commerce Court of Arbitration in 2018 recognized her expertise in international commercial dispute resolution. Additionally, her role as Chairperson of the University of Ghana Governing Council in 2025 underscores her commitment to education and institutional leadership.
