President Bola Ahmed Tinubu has welcomed the International Chamber of Commerce (ICC) ruling on the $235 billion claim brought against Nigeria by Sunrise Power over the Mambilla hydropower project.
The tribunal dismissed Sunrise Power’s claims against Nigeria and also ordered the company and its promoter, Leno Adesanya, to reimburse the Nigerian government 75 per cent of the legal fees and expenses it incurred in the arbitration
In its final decision, signed by the three-member tribunal, the panel rejected Sunrise’s request for a declaration that Nigeria had breached its contractual obligations under the settlement agreement and the addendum
The tribunal also dismissed Sunrise’s claim seeking an order compelling Nigeria to pay the company $400 million
The amount comprised a $200 million settlement sum and a further $200 million default sum
The panel further declared that Adesanya, the promoter of Sunrise, is bound by the arbitration agreement with Nigeria under the settlement agreement and the addendum
It also ruled that it has jurisdiction over Nigeria’s counterclaim against Adesanya and his firm
Reacting in a statement he personally signed, the President said the ruling has cleared “the single biggest legal hurdle that has paralysed the Mambilla hydro power project for years”
