The International Court of Justice in The Hague rejected the claim in which Nicaragua sought to obtain navigational rights of the Colorado River, in Costa Rica.
Nicaragua raised the question last year, responding to Costa Rica’s demands that the government of Daniel Ortega invaded and caused environmental damage to the Isla Calero, an area in the most northen point of the Limón province.
The two countries have been locked into an international court battle following the alleged invasion by Nicaragua of Costa Rican territory in October 2010.
At the time of the filing, the demand by the Ortega administration for the right to navigate the Colorado river, an area that is strictly within Costa Rica’s sovereignty, seemed to be in retaliation for the Calero incident.
Nicaragua argued before the International Court that 90% of the flow of the Colorado comes from Nicaragua.
Costa Rica objected to the demands by its neighbour.
The international court said Nicaragua’s requests were “unacceptable within current procedures.”
Costa Rica’s Foreign Ministry posted the court’s ruling on its website.
