Maritime border Defined
Joint Authority Model
Summary:
After years of failed negotiations, Guinea Bissau and Senegal agreed to arbitrate their pre-independence 1960 maritime boundary agreement established between Portugal and France. The 1989 tribunal ruled in favour of the original agreement. The case was then taken to the ICJ, which confirmed, in 1991, the validity of 1989 tribunal judgement.
In 1993, further negotiations produced a Management and Cooperation Agreement in October
1993 and a supplementary Protocol in 1995 that established a wedge-shaped ‘Area of
joint exploitation’ (Joint Area) straddling the 1960 delimitation line, as well as a further zone of overlapping claims. The zone starts at the land boundary and presumably extends to the outer limits of their maritime claims. Hydrocarbon resources from the exploitation of the continental shelf shall be shared Eighty-five per cent to Senegal, Fifteen per cent to Guinea-Bissau. In the event of new discoveries, these proportions shall be revised, and such revisions shall depend on the quantity of resources discovered. The Agreement mandates the establishment by subsequent agreement of an ‘International Agency’ to exploit the Joint Area. The JDA has been successful in encouraging exploration efforts in the area.
Split:
Resources of the continental shelf:
85 per cent to Senegal; 15 per cent to Guinea-Bissau.
In the event of new discoveries, these proportions shall be revised, and such revisions shall depend on the quantity of resources discovered.
