The High Court’s Specialised Division has blocked attempts to introduce email messages and pension payment records. These documents were put forward by lawyers representing Kwabena Adu-Boahene. They are accused in the ongoing National Signals Bureau (NSB) trial. The court made its decision on Tuesday, May 12, 2026. This occurred during the questioning of the third prosecution witness.
Defence lawyers first wanted to show email conversations. These emails were between the witness and pension fund managers. These managers were linked to Advantage Solutions Limited. The third accused company is Advantage Solutions Limited. Deputy Attorney-General Justice Srem-Sai opposed this move. He argued the emails were not important to the case. The prosecution stated the emails were from August 2024. This was four years after the alleged illegal transactions. They argued no clear link existed between the emails and the charges.
Defence counsel Samuel Atta Akyea argued differently. He said the prosecution portrayed the first two accused as running a criminal operation. They used Advantage Solutions Limited for this. He explained the emails would show the company was a real business. It was an active and legitimate company. The prosecution cited Section 52 of the Evidence Act. This law allows courts to reject evidence. This happens when other legal issues outweigh its value. The court ruled against admitting the emails. It found the proposed evidence was not relevant to the charges.
A second effort by the defence failed. They tried to submit receipts for pension contributions. These had been paid to pension managers. The Deputy Attorney-General raised similar objections. He argued these receipts were also irrelevant. Following these rulings, defence lawyers changed their questions. They moved to other areas during the cross-examination. Adu-Boahene, his wife Angela Boateng, and Advantage Solutions Limited are on trial. They face allegations of misusing GHS 49 million. This money was meant for government cybersecurity software. The prosecution claims the funds moved through many companies. They ended up at Advantage Solutions Limited. This company allegedly used the money to buy properties. These properties are in Accra, Kumasi, and London.
The case continues on Wednesday, May 13, 2026. The cross-examination of the third prosecution witness will proceed. This legal development highlights the strict rules of evidence in Ghanaian courts. It also shows the prosecution's focus on proving direct financial links to the alleged GHS 49 million in misappropriation. The defence’s strategy to establish the legitimacy of Advantage Solutions Limited has faced a significant hurdle. Future proceedings will likely concentrate on direct financial flows and transactions related to the core charges.
