The Supreme Court has unanimously thrown out a legal challenge to the constitutional validity of the Office of the Special Prosecutor (OSP), affirming that Parliament lawfully established the anti-corruption body.
The decision, delivered on Wednesday, 29 July, confirmed that the Office of the Special Prosecutor Act, 2017 (Act 959) is consistent with the 1992 Constitution.

The ruling also addressed the constitutional relationship between the OSP and the Attorney-General, clarifying that the Attorney-General retains the authority under Article 88 to discontinue criminal prosecutions initiated by the Office.
The case was brought by private legal practitioner Noah Adamtey, who argued that Parliament had exceeded its constitutional authority by granting the OSP prosecutorial powers that operate independently of the Attorney-General.
Adamtey contended that Article 88 of the Constitution exclusively vests such powers in the Attorney-General, and that only a constitutional amendment could lawfully transfer comparable authority to a separate institution.
The Attorney-General aligned with aspects of that argument during proceedings, maintaining that while prosecutorial functions may be delegated, they must remain subject to the Attorney-General's control rather than being exercised autonomously by a statutory body.
The OSP sought to join the proceedings as an interested party but was refused by the court, which held that the constitutional questions at stake could be adequately resolved between the existing parties.
Several civil society organisations were, however, admitted to participate, given their established roles in governance and anti-corruption work in Ghana.
Supreme Court's Ruling on OSP and the Attorney-General
After hearing all submissions, the Supreme Court concluded that Parliament acted squarely within its constitutional mandate in establishing the OSP as an independent anti-corruption institution. Act 959 was therefore upheld in its entirety.

Critically, the judgment drew a firm line on the limits of the OSP's independence: the Attorney-General's constitutional powers remain fully intact, including the express authority to terminate prosecutions that the Office has commenced.
The ruling stops short of undermining the OSP's operational independence while making clear that the Attorney-General's supervisory role in criminal prosecutions is not diminished by the existence of the Office.
The decision is expected to provide long-awaited judicial clarity on the constitutional boundaries governing one of Ghana's most prominent anti-corruption institutions, settling a dispute that had raised fundamental questions about the limits of Parliament's legislative authority in structuring prosecutorial bodies.
