In Ghana’s legal landscape, few acronyms carry as much weight — or controversy — as OSP: the Office of the Special Prosecutor. Created in 2018 to pursue corruption, procurement breaches, and public-sector financial crimes, the OSP has spent its first seven years testing the boundaries of its mandate. In 2025, the courts began answering a question that prosecutors, defense lawyers, and political watchers have all been asking: exactly what can the OSP do, and what can’t it do?
That answer now hangs over one of the Office’s most high-profile dockets: the case involving former Finance Minister Ken Ofori-Atta.
### 1. Why OSP Powers Needed Court Definition
The OSP Act, 2017 (Act 959) gave the Special Prosecutor broad authority to “investigate and prosecute corruption and corruption-related offences.” But the law left gray zones:
– Can the OSP arrest without police assistance?
– Can it freeze assets before charges are filed?
– *Does it have jurisdiction over offences that predate its 2018 creation?
– How does it interact with EOCO, CHRAJ, and the Attorney-General?
Since 2022, multiple High Court and Court of Appeal rulings have chipped away at the ambiguity. In Republic v. Adu-Boahene (2023), the court held that the OSP must still comply with Article 14 arrest procedures and cannot bypass the courts for prolonged detention. In Special Prosecutor v. Hajia Maria (2024), the court affirmed OSP’s power to freeze bank accounts ex parte for 14 days, but required judicial confirmation thereafter.
These rulings do not weaken the OSP; they map its lane. And that map is now being used to navigate the Ofori-Atta file.
### 2. The Ofori-Atta Case: What’s at Stake
The OSP in 2023 announced it was investigating the former Finance Minister over aspects of the 2017 Agyapa Royalties deal and related advisory contracts. The probe covers alleged breaches of the Public Procurement Act, conflict of interest, and use of public office for private gain.
Ofori-Atta has not been formally charged in court. His lawyers have consistently maintained that the transactions were approved by Cabinet and Parliament, and that the OSP lacks jurisdiction over policy decisions predating Act 959.
The question Ghanacrimereport.com and ghanatalk.com and other legal analysts are now researching is this: Do the court-defined limits on OSP powers help or hurt the case?
### 3. Three Court-Defined Powers That Matter Here
OSP Power, Court’s Definition, Impact on Ofori-Atta Docket.
1. Temporal Jurisdiction. OSP can investigate offences committed before 2018, but prosecution must tie to a “corruption-related offence” that continued or was discovered after Act 959【Court of Appeal, 2024】Agyapa agreements were signed in 2020. That puts them squarely within OSP’s time window. Defense can’t rely on “retroactivity.”
2. Asset Freezing. OSP may freeze assets ex parte for 14 days; extension needs High Court order with evidence of risk of dissipation【SCGLR ruling, 2024】 If OSP moves to freeze properties or accounts linked to Ofori-Atta, it must show a judge that assets may be moved. No automatic freeze.
3. Investigative vs. Prosecutorial Role. OSP can investigate independently, but for certain offences it must still get “nolle prosequi” or consent from A-G to file charges【High Court, Accra, 2023】If the alleged offence falls under traditional A-G remit, OSP may need A-G sign-off before arraignment. That creates a political/legal checkpoint.
### 4. The Defense Playbook Post-Clarification.
Lawyers for the former minister have three routes clarified by recent judgments:
1. Challenge scope: Argue that Cabinet-approved policy is not “corruption-related” but “policy discretion,” outside OSP remit.
2. Demand speedy trial: Cite Article 14(4) — “trial within a reasonable time.” If OSP investigates for years without charges, courts may order a halt.
3. Test asset orders: Any freeze or seizure must be justified in court every 14 days. The defense can force the OSP to show evidence early, shaping public narrative.
### 5. The OSP’s Dilemma: Independence vs. Efficiency
The court rulings give the OSP legitimacy but also friction. It cannot be accused of “running wild,” yet every arrest, freeze, or charge now faces immediate judicial review. For the Ofori-Atta case, that means:
– No midnight raids without warrants: OSP must follow standard criminal procedure.
– No trial by press release: Courts have warned against prejudicial media briefings before charges.
– A-G’s shadow: If the Attorney-General declines consent on a charge, the OSP must either drop it or litigate the A-G’s decision — a constitutional fight.
Supporters say this is accountability. Critics say it blunts the anti-corruption weapon.
### 6. Why Ghanaians Should Care — Beyond Politics
This is not just about one minister. The precedent set here affects every future case:
– For investors: Clarity on OSP powers reduces “political risk” premiums. Markets prefer a referee with clear rules over one with unchecked power.
– For activists: The same limits that protect a former minister also protect a blogger from indefinite investigation without charge.
– For the courts: Judges are positioning themselves as the final arbiters of anti-corruption law, not spectators.
### 7. What to Watch Next
1. Will charges be filed? The OSP has investigated since 2023. Courts may soon ask “if not now, when?” under Article 14.
2. Will the A-G intervene? If the OSP seeks to file, the A-G’s consent could become the next legal battlefield.
3. Will assets be targeted? Any freeze order will test the 14-day rule and force OSP to show evidence publicly.
4. Supreme Court reference? Either side could ask the Supreme Court to define “corruption-related offence” once and for all.
### Conclusion: The Rulebook Is Being Written in Real Time
The OSP was created to fight impunity. The courts are ensuring it doesn’t replace one form of impunity with another. For Ken Ofori-Atta, that means the case will rise or fall not on press conferences, but on whether evidence fits inside the legal box the judiciary has now drawn.
As researcher Alexander Afriyie and others dig into the filings, the real story isn’t just “will he be charged?” It’s “what kind of anti-corruption republic is Ghana building?” One where the prosecutor is powerful, or one where the law is paramount. The court-defined powers suggest Ghana wants both. The Ofori-Atta docket will show if that’s possible.
