AS Nigeria awaits judgment in the high-profile trial of former Minister of Power, Engr. Sale Mamman, the case has evolved into more than a routine corruption proceeding. It has become a litmus test for evidentiary standards, prosecutorial depth, and public perception of justice.
Over months of hearings, multiple reports across national media have painted a fragmented picture. However, when the courtroom record is examined holistically, a clearer narrative emerges, one that raises critical questions about whether the prosecution has met the legal threshold required for conviction.
At the centre of the case is the alleged diversion of over ₦33 billion linked to the Mambilla-Zungeru power project. The Economic and Financial Crimes Commission (EFCC) constructed its case around financial flows through multiple corporate accounts and a Central Bank of Nigeria (CBN)-domiciled project account. Yet, witness testimonies, particularly under cross-examination, have consistently introduced gaps that the court cannot ignore.
A recurring theme across proceedings is the absence of direct linkage. Key prosecution witnesses, including banking officials and Bureau de Change operators, admitted under oath that they neither knew the defendant personally nor could establish any operational relationship between him and the accounts under scrutiny. Even more telling, witnesses such as PW9 and PW11 confirmed that all instructions they received came from a project accountant, not the minister, and that they never conducted any transaction directly with him.
The documents tendered, including account statements, mandates, and compliance records, were procedural in nature. Crucially, none demonstrated ownership, signatory authority, or beneficial control by the former minister. Evidence from the Office of the Accountant General further confirmed that payments were processed through the Remita platform by designated officials, none of whom included the defendant.
Even more significant is the issue of the Special Project Account. Testimony confirmed that the account was managed by officials from the Office of the Accountant General and the CBN, not the Ministry of Power. The implication is structural: without signatory authority or administrative control, attributing transactional liability to the minister becomes legally tenuous.
The prosecution’s own witnesses also introduced contradictions that complicate its financial narrative. While investigators claimed the funds originated from a China Exim Bank loan, documentary evidence showed that such loans were paid directly to contractors. Investigators further admitted they neither verified total disbursements from the bank nor confirmed actual releases from government accounts during the defendant’s tenure.
Timeline discrepancies further complicate the prosecution’s narrative. Evidence presented indicates that the financial activities in question began before Mamman assumed office and continued after his tenure ended. This temporal mismatch raises a fundamental legal question: on what basis can responsibility be assigned to an individual for actions occurring outside their period of authority?
Equally damaging is the prosecution’s failure to establish the source and unlawful origin of the alleged ₦33 billion. Witnesses who handled the funds admitted they did not know where the money came from, relying instead on what investigators told them. In criminal law, such hearsay cannot establish the predicate offence required for money laundering.
Another critical evidentiary gap lies in the non-production of key materials. Multiple witnesses confirmed the existence of handwritten transaction record books documenting disbursements and recipients, which were seized by investigators. Despite formal requests by the defence, these materials were never produced in court. Under established legal principles, withholding such potentially material evidence raises adverse inferences and directly implicates the defendant’s constitutional right to fair hearing.
The trial has also spotlighted procedural controversies. The defence argued that failure to provide these documents deprived the accused of the “facilities” required to prepare his case, as guaranteed under Section 36 of the Constitution. Additional concerns included allegations of trial by ambush, such as late disclosure of video evidence and the calling of witnesses not previously listed, limiting the defence’s ability to respond adequately.
Further procedural tension arose when the defence attempted to recall a key witness under statutory provisions but was denied, effectively closing its case under constrained circumstances. These developments introduce broader questions about whether the trial process itself met constitutional standards of fairness.
Beyond evidentiary gaps, the prosecution’s case also faces structural weaknesses. The charge of money laundering is predicated on criminal breach of trust, yet no evidence was led to show that funds were ever entrusted to the defendant. Testimony consistently established that financial control rested with designated accounting officers, not the minister. Without proof of entrustment, the foundation of the charge becomes legally unstable.
Even the arithmetic of the prosecution’s case has come under scrutiny. Witnesses admitted disbursing sums that, when aggregated, exceed the total amount allegedly diverted. This creates a mathematical inconsistency that undermines the coherence of the entire financial narrative.
Public discourse has not been immune to distortion. Selective reporting and headline-driven narratives have, at times, overstated the strength of the prosecution’s case, creating an impression of imminent conviction. Yet, courtroom realities suggest a more nuanced picture, one where evidentiary gaps, contradictions, and procedural concerns define the trajectory.
Beyond the individual case, broader institutional questions have surfaced. Why were key officials who managed the project account not subjected to the same level of scrutiny? Why does the investigative scope appear narrowly focused despite a multi-year transaction window spanning different administrations? These are not merely political questions; they go to the heart of prosecutorial completeness.
As judgment approaches, the court is faced with a singular task: to determine whether the evidence presented satisfies the stringent requirements of criminal conviction. The principle remains unchanged: he who alleges must prove.
If the ruling ultimately favours the former minister, it will not merely be a personal vindication. It will reaffirm a foundational tenet of the justice system: that accountability must be anchored in credible, direct, and corroborated evidence, not inference, assumption, or public sentiment.
In the end, this case may be remembered less for its allegations and more for what it reveals about the standards of proof in Nigeria’s fight against corruption. The verdict will speak, but the record already tells a story, one of a prosecution challenged not by rhetoric, but by the weight of its own evidence.
