A Federal High Court in Abuja on Wednesday convicted and sentenced former Minister of Power, Saleh Mamman, to a cumulative 75 years imprisonment in absentia over a ₦33.8bn money laundering scandal linked to the Zungeru and Mambilla hydroelectric power projects.
The trial judge, Justice James Omotosho, found Mamman guilty on all 12 counts bordering on conspiracy and money laundering filed against him by the Economic and Financial Crimes Commission.
The judge ruled that the prison terms would run consecutively, bringing the total sentence to 75 years.
Justice Omotosho held that Mamman deliberately absented himself from court on the day of judgment and during the previous adjourned sitting in a bid to frustrate the administration of justice.
He agreed with counsel for the EFCC, Rotimi Oyedepo (SAN), that the Administration of Criminal Justice Act, 2015 empowered the court to proceed with sentencing despite the defendant’s absence.
The court consequently sentenced the former minister to seven years imprisonment each on Counts 1, 2, 3, 6, 7, 8, 9, 10, 11 and 12 without an option of fine.
Mamman was also sentenced to three years imprisonment on Count 4 with an option of a ₦10m fine, and two years imprisonment on Count 5 without an option of fine.
Justice Omotosho further ordered that the sentence would commence from the date of Mamman’s arrest since he was convicted in absentia.
The judge directed security agencies within and outside Nigeria, including Interpol, to arrest the convict wherever he is found and hand him over to the Nigerian Correctional Service to serve his jail term.
The court also ordered the final forfeiture of two Abuja properties linked to the former minister, alongside various sums recovered in different currencies by anti-graft agencies.
In addition, the court ordered Mamman to refund the outstanding balance from the ₦22bn already traced to the Zungeru and Mambilla hydroelectric power projects out of the ₦33.8bn allegedly diverted.
The conviction followed a lengthy trial instituted by the EFCC, which accused Mamman of conspiring with ministry officials and private companies to divert funds earmarked for the two power projects.
Mamman was arraigned on July 11, 2024 on a 12-count charge and pleaded not guilty.
During the trial, the EFCC called 17 witnesses and tendered 43 exhibits to support its case.
Following the close of the prosecution’s case, the former minister filed a no-case submission on November 19, 2025, contending that the EFCC had failed to establish sufficient evidence against him.
However, Justice Omotosho, in a ruling delivered on December 11, 2025, dismissed the application and held that the prosecution had established a prima facie case requiring the defendant to open his defence.
The matter was subsequently adjourned for continuation of defence before Wednesday’s judgment brought the proceedings to a close.
The case, regarded as one of the most significant corruption convictions in recent years, stemmed from Mamman’s arrest and detention by the EFCC on May 10, 2021.
