The International Court of Justice also known as the World Court ruled largely in favour of Somalia in a case filed by Somalia against Kenya over contested parts of the Indian Ocean believed to be rich in oil and gas.
The court’s ruling gives Somalia the right to exploit oil and gas reserves in the region.
The panel of 14 judges sitting in The Hague said that Kenya had not proved that Somalia had previously agreed to its claimed border.
They rather drew a new line which has split the disputed area in two.
Both countries laid claim to a 38,000 sq. mile (100,000 sq. km) triangle in the waters off the East African coast and accused the other of an illegal grab for resources.
The sea boundary row started in 2012 after Somalia accused Kenya of illegally awarding exploration rights in the waters to multinationals Total and Eni.
In 2014, Somalia brought the case at the United Nation’s highest court for disputes between states after negotiations to resolve the dispute failed.
On Friday, Kenya withdrew from the automatic jurisdiction of the court after boycotting its hearings in March and joined many other members of the U.N. in withdrawing its recognition of the Court’s compulsory jurisdiction.
It described the case as a “flawed judicial process” added that there was “inherent bias” and that the court was an unsuitable way to resolve the dispute.
Kenya’s refusal to recognise the ICJ’s jurisdiction has made it unclear on what will happen because the court has no means to enforce its rulings.
ICJ is supposed to be the final arbiter in disputes between nations.
