Ghana’s Supreme Court has unequivocally affirmed the independent prosecutorial mandate of the Office of the Special Prosecutor (OSP). This landmark 7-0 decision settles a significant legal dispute over the anti-corruption institution’s powers.
Special Prosecutor Kissi Agyebeng announced the ruling, stating it upholds the OSP’s constitutional basis under the Office of the Special Prosecutor Act, 2017 (Act 959). The decision, delivered on July 29, expressly overturns previous lower court judgments that had challenged the OSP’s authority. This legal clarity allows the OSP to fully pursue its mandate of investigating and prosecuting corruption-related offenses.
The Supreme Court’s ruling provides crucial stability for Ghana’s anti-corruption framework, reinforcing institutional integrity. It ensures that a key body tasked with safeguarding public funds can operate without legal ambiguity. This decision is vital for investor confidence and Ghana's broader economic governance, signaling a commitment to combating financial malfeasance. Previous legal challenges had created uncertainty, potentially deterring foreign direct investment and undermining efforts to improve public sector accountability.
Mr. Agyebeng emphasized the importance of the Supreme Court’s verdict, calling it a “well-reasoned and emphatic” decision. He noted that the ruling in Noah Ephraem Tetteh Adamtey v Attorney General directly addressed the constitutionality of the OSP’s powers. This judicial endorsement strengthens the OSP’s position against corruption, ensuring its legal foundation remains solid.
The ruling has significant implications for ongoing and future anti-corruption efforts. It removes the legal paralysis that had stalled investigations and prosecutions, allowing the OSP to resume its work with full legal backing. Decision-makers and markets will closely watch how this renewed mandate translates into tangible results, particularly concerning asset recovery and high-profile corruption cases. The ability of the OSP to operate effectively is critical for maintaining public trust and ensuring responsible use of state resources.
Before this Supreme Court decision, an Accra High Court had, on April 15, 2026, struck down parts of Act 959. That ruling declared the OSP lacked an independent prosecutorial mandate. Mr. Agyebeng explained this High Court decision invalidated OSP prosecutions and nullified convictions and assets secured. It also directed that OSP cases be transferred to the Attorney General, effectively halting the OSP's operations nationwide.
This legal uncertainty brought the OSP’s investigative and prosecutorial work to a standstill. Investigations were hampered, and prosecutions stalled across the country. Mr. Agyebeng noted that corrupt actors became emboldened during this period. The Supreme Court’s intervention has now resolved this critical issue, restoring the OSP’s operational capacity.
Mr. Agyebeng highlighted the OSP’s performance record despite these challenges. As of December 31, 2025, the OSP was prosecuting 33 individuals. It also had 79 cases at the full investigation stage and 161 at the preliminary investigation level. The Office had secured seven convictions through court-sanctioned plea bargains, demonstrating its effectiveness even under duress.
The OSP’s impact extends beyond prosecutions and investigations. It has also focused on asset recovery and corruption prevention. By December 2025, the OSP had secured financial recoveries totaling GHS 8.5 million and $2 million. It also recovered substantial movable and immovable assets involved in ongoing proceedings, showcasing its commitment to reclaiming stolen state funds.
Furthermore, the OSP prevented significant financial losses through corruption risk assessments. These assessments focused on Ghana’s natural resources and strategic national assets. Mr. Agyebeng credited the OSP with safeguarding the Tema Oil Refinery, which is now operational after years of inactivity. This intervention prevented the facility from being “pawned off,” preserving a key national asset.
The OSP also contributed to reforms in the Customs sector. Its scrutiny led to improvements in the auction of seized items. It also reduced the abuse of the Customs advance ruling regime, enhancing revenue collection. Reforms stemming from the OSP’s review of the government payroll system saved the country over GHS 100 million. This demonstrates the OSP’s significant financial contribution to the state.
Mr. Agyebeng asserted that the OSP has saved the nation more than 20-fold the total amount of money released to it. This indicates the Office has fully justified the resources invested in its establishment. He maintained that the OSP’s impact should be measured by facts, not public applause or political sentiment. Its performance should be assessed based on investigations, prosecutions, assets recovered, losses prevented, and systems corrected. The Supreme Court’s decision now provides a definitive answer regarding the OSP's constitutional authority to prosecute cases independently.
