Judicial Overreach or Constitutional Necessity? Examining the Supreme Court's Intervention in Parliamentary Proceedings in Ghana: The Case of Alexander Afenyo Markins v. The Speaker of Parliament & Attorney General

The case of Alexander Afenyo Markins v. The Speaker of Parliament & Attorney General presents a pivotal constitutional dispute concerning the balance between judicial oversight and parliamentary autonomy under Ghana's 1992 Constitution. The Supreme Court, invoking its interpretative and enforcement jurisdiction under Articles 2(1) and 130(1), ruled by 5-2 majority that the nomination of four Members of Parliament under different political affiliations did not amount to a vacation of their seats under Article 97(1)(g) and (h) of the 1992 Constitution of Ghana. The Court further held that the Speaker of Parliament exceeded his constitutional mandate by declaring the seats vacant. While some view this judgment/ruling as a necessary safeguard for constitutional supremacy, critics argue that it constitutes judicial overreach, undermining the principle of parliamentary sovereignty. This article critically examines whether the Court's intervention disrupts the separation of powers, drawing on key constitutional jurisprudence. It also analyzes Justice Amadu Tanko's dissenting opinion, which contends that the ruling usurped the High Court's exclusive jurisdiction under Article 99 of the 1992 Constitution. The article concludes by assessing the broader implications of the judgment on Ghana's constitutional framework and democratic governance.
