The High Court’s Specialised Division has dealt a setback to former National Signals Bureau (NSB) Director-General Kwabena Adu-Boahene and his co-accused, refusing to admit email correspondence and pension payment receipts as evidence in their ongoing trial.
The ruling came down on Tuesday, May 12, 2026, during the cross-examination of the third prosecution witness.
Defence lawyers had sought to tender two sets of documents. The first was email exchanges between the witness and third-party pension managers linked to Advantage Solutions Limited, the third accused company. The second was receipts of pension contributions paid to the same managers.
Deputy Attorney-General Justice Srem-Sai opposed both attempts, arguing the documents bore no relevance to the charges before the court. The prosecution pointed out that the emails dated from August 2024—four years after the alleged criminal transactions at the heart of the case.
In response, defence counsel Samuel Atta Akyea argued that the prosecution’s own summary of facts sought to portray the first and second accused as operators of a criminal enterprise through Advantage Solutions Limited. The emails and receipts, he contended, would demonstrate that the company was a legitimate, ongoing business.
The prosecution countered by citing Section 52 of the Evidence Act, which allows a court to reject evidence where its probative value is outweighed by other legal considerations.
The court agreed, ruling that the proposed evidence was not relevant to determining the charges. Both attempts to tender the documents were rejected.
Following the rulings, defence lawyers continued with other lines of questioning during cross-examination.
Adu-Boahene, his wife Angela Boateng, and Advantage Solutions Limited are standing trial over allegations that GH¢49 million intended for government cybersecurity software was misappropriated. The prosecution alleges the funds were routed through a network of companies before ending up at Advantage Solutions Limited, which then used the money to acquire properties in Accra, Kumasi, and London.
The case has been adjourned to Wednesday, May 13, 2026, for the cross-examination of the third prosecution witness to continue.
