Supreme Court Clarifies Limits of Review in High‑Profile Cases

A unanimous ruling by Ghana’s Supreme Court on 3 September 2026 dismisses former Information Minister Kojo Oppong Nkrumah’s review application, underscoring that review is a narrow tool reserved for exceptional circumstances. The decision clarifies procedural boundaries around interlocutory injunctions and legal‑vacation rules, and sets a precedent for future challenges to single‑Justice orders.

Legal Question at Issue

The core issue is whether a former minister can invoke the Supreme Court’s review jurisdiction to overturn a single‑Justice interlocutory injunction. The court had to decide if the petition met the stringent “exceptional circumstances” threshold that distinguishes review from an ordinary appeal.

Governing Principles

The decision relies on principles codified in the Constitution of the Republic of Ghana and the Rules of Court concerning review. Review is described as a limited remedy, not a substitute for appellate review, and is confined to situations where a single‑Justice decision is manifestly erroneous or involves a jurisdictional error. The Court emphasized that review must be exercised sparingly to preserve the judiciary’s procedural integrity.

Analysis of the Ruling

The Supreme Court, in a unanimous opinion, found the petition "unmeritorious". The panel held that the eight ground‑claims presented by Oppong Nkrumah failed to meet the exceptional‑circumstances standard. The Court clarified that misapplication of legal‑vacation rules to a criminal proceeding, by itself, does not justify review unless accompanied by evidence of a clear breach of jurisdiction.

Strongest Counterargument

Oppong Nkrumah contended that the single‑Justice order overstepped the Court’s authority by addressing the merits of an underlying dispute and that the application of legal‑vacation rules to the criminal context was improper. His argument hinged on the view that a single‑Justice ruling can be reviewed if it effectively encroaches on the appellate system.

Practical Implications

1. Litigants’ Strategy – Lawyers will be more cautious when filing review applications against single‑Justice decisions, ensuring that the grounds demonstrate a jurisdictional error rather than a simple disagreement with the merits. 2. Procedural Clarity – The ruling reinforces the boundary between interlocutory injunctions and substantive appeals, providing clearer guidance for courts dealing with politically sensitive matters. 3. Judicial Efficiency – By restricting review to truly exceptional cases, the Court helps prevent procedural bottlenecks that could arise from frequent review petitions.

Possible Reform or Response

A practical reform would be the enactment of a statutory guideline detailing the precise criteria for review, including a mandatory check-list of factors that must be satisfied. This would standardize the process and reduce uncertainty for litigants. Alternatively, the Court could issue a supplemental order directing lower courts to provide a brief written summary of any legal‑vacation rule application before proceeding with an interlocutory injunction.

Conclusion

The Supreme Court’s decision serves as a critical reminder that review is a narrowly tailored tool, intended to correct clear jurisdictional errors rather than to substitute for appellate review. By reaffirming procedural boundaries, the ruling preserves the balance of power between the judiciary and executive while ensuring that high‑profile disputes are resolved through the proper channels.
