Nigeria Wins $3.38bn Mambilla Arbitration Battle As ICC Rejects Sunrise Claims
Nigeria Wins $3.38bn Mambilla Arbitration Battle As ICC Rejects Sunrise Claims
Nigeria has won a major international arbitration battle over the long-delayed Mambilla Hydroelectric Power Project, after an International Chamber of Commerce (ICC) tribunal in Paris rejected claims by Sunrise Power and Transmission Company Limited that had put the country’s potential financial exposure at more than $3.38 billion.
The ruling, issued on September 17, 2026, is a significant development for the proposed 1,500MW Mambilla power project in Taraba State, which has been stalled for years by a combination of legal, contractual, financing and implementation challenges.
President Bola Ahmed Tinubu welcomed the decision, describing it as the removal of what he called the biggest legal obstacle to the project’s progress.
The dispute dates back to a 2003 agreement concerning the development of the Mambilla project. Sunrise Power subsequently commenced arbitration proceedings against Nigeria at the ICC in October 2017, initially seeking about $2.35 billion over an alleged breach of contract.
The parties later entered into a settlement agreement in 2020 under which Nigeria was to pay Sunrise $200 million. A subsequent disagreement over the implementation of that agreement led to another arbitration.
In the latest proceedings, Sunrise sought about $680 million, including the settlement sum and interest. A separate claim connected to disputes over the development of the Mambilla project was valued at more than $2.7 billion in compensation and interest.
Together, the related claims created potential exposure of more than $3.38 billion for Nigeria.
The ICC tribunal rejected Sunrise’s claim that Nigeria had breached its obligations under the settlement agreement and its addendum. It also dismissed the company’s request for Nigeria to pay $400 million, comprising the $200 million settlement sum and an additional $200 million claimed as a default payment.

The tribunal further held that Leno Adesanya, the promoter of Sunrise Power, was bound by the arbitration agreement under the settlement arrangement. It also confirmed its jurisdiction over Nigeria’s counterclaim against Adesanya and his firm.
Rather than ordering Nigeria to pay the amounts sought by Sunrise, the tribunal directed Sunrise and Adesanya to reimburse Nigeria for 75 per cent of its legal fees and expenses incurred in the arbitration.
The legal costs were assessed at approximately $11.82 million. About $2.5 million is expected to be recovered from funds held in escrow by the ICC, while Sunrise and Adesanya are required to pay the remaining $9.32 million, with interest at 10 per cent annually, compounded annually, from notification of the final award until payment.
The tribunal also fixed the arbitration costs at approximately $1.66 million, with Sunrise and Adesanya responsible for 75 per cent and Nigeria responsible for the remaining 25 per cent.
The three-member tribunal was chaired by Melaine van Leeuwen, with Stavros Brekoulakis and Simon Nesbitt serving as co-arbitrators. Nigeria’s external legal team was led by Elizabeth Oger-Gross and Tolu Obamuroh of Paul Hastings LLP.
The outcome ends a major phase of a dispute that has followed the Mambilla power project for nearly a decade in international arbitration and more than two decades from the original project agreement.
The original proposal envisaged a 3,050MW hydroelectric plant in Taraba State under a build-operate-transfer arrangement. The project was subsequently revised as the government sought to reduce its cost and improve its prospects of attracting financing.
In 2021, the Federal Government announced that the planned capacity would be reduced by about half, from 3,050MW to approximately 1,525MW. The scheme was subsequently rescoped to around 1,500MW to make it more financially viable and “bankable” for lenders.
The original project had been associated with an estimated cost of roughly $5 billion to $5.8 billion, while the rescoped project has been put at around $4 billion in previous government discussions.
The prolonged delay has meant that the Mambilla scheme has yet to become an operational source of electricity despite its potential to significantly increase Nigeria’s generation capacity.
President Tinubu, in his reaction to the ICC ruling, commended Attorney-General of the Federation and Minister of Justice, Lateef Fagbemi, officials of the Federal Ministry of Justice and Nigeria’s external legal team for their role in defending the country.
He also acknowledged former President Olusegun Obasanjo and the late former President Muhammadu Buhari, who testified during the arbitration proceedings, as well as former Ministers of Power Babatunde Fashola and Suleiman Adamu and other witnesses and experts.
Tinubu also credited the National Security Adviser and the Economic and Financial Crimes Commission (EFCC) for their roles in the broader matter.
The President said Nigeria remained committed to working with genuine investors and honouring its legal obligations while defending the country against claims it considers detrimental to the national interest.
The original 2003 contract has also been the subject of separate domestic legal proceedings and investigations. Tinubu said the contract was not authorised by the Federal Executive Council (FEC). Those domestic proceedings are distinct from the ICC arbitration, which has now been decided in Nigeria’s favour.
The arbitration victory, however, does not mean that the 1,500MW Mambilla project is immediately ready for construction or electricity generation.
The government still has to address major issues involving project financing, construction, engineering, transmission infrastructure and implementation arrangements. Previous plans have included financing discussions involving the Export-Import Bank of China, while the project’s restructuring was intended to improve its bankability.
With the arbitration dispute now resolved, the focus shifts to securing the funding and completing the arrangements required to move the Mambilla project from a long-delayed proposal to actual construction and, ultimately, electricity generation.

Kogi: Troops Destroy Kidnappers’ Hideout, Recover 1,000 Rounds of Ammunition, Six Motorcycles
Troops of the Nigerian Army have destroyed a suspected kidnappers’ hideout in Edimogbo Forest, Igalamela/Odolu Local Government Area of Kogi State, recovering 1,000 rounds of ammunition, six motorcycles and other items during an offensive operation.
The operation, according to the Army, followed credible human intelligence indicating that suspected kidnappers were hiding in the forest.
The spokesperson for the Nigerian Army, Appolonia Anele, disclosed this in a statement on Monday, saying the troops recovered a substantial cache of ammunition and other materials from the criminal camp.
Anele explained that the suspected criminals opened fire to alert other members of their group after sighting the advancing troops before fleeing into the forest.
She said the soldiers immediately pursued the fleeing suspects deep into the forest, but were unable to establish contact with them.

“The troops immediately pursued the fleeing criminals deep into the forest, but no contact was made. The troops, however, destroyed the criminal camp, including all supportive structures,” she stated.
According to the Army spokesperson, the recovered items included 1,000 rounds of 7.62mm x 54 ammunition, seven bandoliers, two shovels, a hand pump, a mobile phone, a Glo modem and six motorcycles.
Other items recovered from the hideout included soap, a jerrycan containing petrol, clothing and pairs of shoes.
The Army said troops were still combing the forest and surrounding areas in an effort to track down the fleeing suspects.
The operation forms part of ongoing military efforts to dismantle criminal hideouts, disrupt the activities of suspected kidnappers and improve security across Kogi State.
The recovery of the ammunition and motorcycles is expected to provide further intelligence on the activities and possible movements of the suspected criminal group.
However, the Army did not disclose whether any arrests had been made in connection with the operation as of the time of the announcement.

Nasarawa: Suspected Kidnapper Arrested While Collecting N200,000 Ransom
Troops of the Nigerian Army, working in collaboration with operatives of the Department of State Services (DSS), have arrested a suspected kidnapper while allegedly collecting a ₦200,000 ransom from a female resident of Nasarawa State.
The suspect, identified as Mukaila Iliyasu, was apprehended at Akwaba in Eggon Local Government Area during an intelligence-led operation involving troops of Sector 2, Joint Task Force Operation Whirl Stroke, and DSS personnel.
The arrest followed intelligence reports that Iliyasu had allegedly threatened to abduct a woman unless she paid him ₦200,000.
The Acting Media Information Officer of Joint Task Force Operation Whirl Stroke, Lieutenant Ahmad Zubairu Zubairu, confirmed the arrest in a statement.
According to the statement, DSS operatives alerted the military to the alleged threat on October 29, prompting a coordinated operation to track down the suspect and prevent the planned abduction.
As part of the operation, a soldier reportedly went undercover and posed as the person assigned to deliver the ransom.

The security operatives subsequently arrested Iliyasu while he was allegedly collecting the money.
They also recovered ₦200,000, believed to be the ransom demanded from the intended victim.
The military described the operation as a successful intelligence-led intervention that prevented a possible kidnapping, highlighting the importance of cooperation among security agencies in tackling criminal activities.
Following his arrest, the suspect was handed over to the DSS for further investigation and possible prosecution.
The Force Commander of Operation Whirl Stroke and General Officer Commanding 5 Division of the Nigerian Army, Major General Moses Kolo Gara, commended the troops and DSS operatives for their professionalism, courage and effective coordination during the operation.
Gara urged security personnel to sustain their collaboration and strengthen intelligence sharing to tackle kidnapping and other security threats across their areas of responsibility.
He also stressed the importance of continued inter-agency cooperation in protecting lives, safeguarding communities and maintaining peace across the region.

US-Convicted Osun Monarch Drags Adeleke to Court, Moves to Stop Appointment of Successor
The deposed Apetumodu of Ipetumodu in Osun State, Oba Joseph Oloyede, has instituted a legal action against Governor Ademola Adeleke, seeking to stop the state government from appointing a new traditional ruler to replace him.
Oloyede, who was removed from the throne following his conviction for fraud-related offences in the United States, is challenging the legality of his deposition and asking an Osun State High Court to prevent the government from filling the vacant stool pending the determination of his suit.
The former monarch is listed as the second claimant in suit number HIF/50/2026, filed before the High Court sitting in Ile-Ife.
In a motion on notice dated September 16, 2026, Oloyede sought an interlocutory injunction restraining Adeleke and other government officials from taking steps to appoint another person as the Apetumodu of Ipetumodu until the substantive case is determined.
He argued that the state government failed to formally notify him of any wrongdoing or give him an opportunity to respond before taking the decision to remove him from the traditional institution.
The monarch also challenged an instrument reportedly signed by Adeleke on May 7, 2026, which formalised his removal from the throne.
Oloyede maintained that the process leading to his deposition violated his right to fair hearing, insisting that he was not given an opportunity to defend himself against the allegations before the government acted.
Other claimants in the suit include Princes Oyewusi Adewusi, Isaac Adewuni and Abiodun Oyetoro. They instituted the action on behalf of themselves and other members of the Latimogun Royal Family of the Aribile Ruling House of Ipetumodu.

The defendants include Governor Adeleke, the Osun State Attorney-General and Commissioner for Justice, the Commissioner for Local Government and Chieftaincy Affairs, Chief Afolabi Adedeji, the Asalu of Ipetumodu and head of the kingmakers, Chief Adesoye Babalola, the Malefon of Ipetumodu, and Ife North Local Government.
The latest court proceedings took place on Monday, November 2, 2026, but the hearing could not proceed because of disagreements over the service of hearing notices on the defendants.
Only counsel to the claimants, O. Ogbewe, and counsel representing the fifth defendant, Soji Oyetayo, appeared before the court.
Ogbewe informed the court that the defendants had been served with the relevant court processes.
However, Oyetayo disputed the claim, telling the court that he had not received the hearing notice. He consequently requested an adjournment to allow proper service on all parties.
In his ruling, Justice Dapo Adeniji adjourned the matter until January 21, 2027, directing that fresh hearing notices be issued and served on the defendants.
The legal battle follows Oloyede’s conviction by the United States District Court for the Northern District of Ohio over his involvement in a multimillion-dollar fraud scheme involving COVID-19 relief funds.
The former monarch was sentenced to 56 months’ imprisonment on August 26, 2025, after pleading guilty to offences involving wire fraud, filing false tax returns and conducting financial transactions involving proceeds of criminal activity.
The US court also ordered him to pay approximately $4.4 million in restitution.
Following the conviction, the Osun State Government initiated steps that culminated in his removal from the traditional stool.
Adeleke approved the deposition in May 2026 after the state government obtained a certified true copy of the American court judgment.
The administration said the decision was necessary to protect the integrity of the traditional institution and subsequently declared the Apetumodu stool vacant.
However, Oloyede’s latest court action challenges the procedure adopted by the state government, particularly the circumstances surrounding his removal and the proposed appointment of a successor.
The outcome of the case could determine whether the state government’s action withstands judicial scrutiny and whether the process of installing a new Apetumodu can proceed without further legal complications.
For now, the traditional stool remains at the centre of a legal dispute, with the court expected to resume proceedings on January 21, 2027.
