Deconstructing the Trias Politica Doctrine in the Post- Apartheid South African Context: Insights on Judicial Hegemony.

This article critically examines the applicability of the Trias Politica Doctrine—originally conceptualized by John Locke and Charles De Montesquieu as the separation of powers among the legislature, executive, and judiciary—in post-apartheid South Africa. Using a qualitative case study approach and document analysis, the authors argue that the judiciary, empowered by the principle of constitutional supremacy, exerts significant influence and control over both the legislative and executive branches, a phenomenon they term "judicial hegemony." The paper presents multiple legal cases where South Africa's Constitutional Court and other courts have overruled or directed legislative and executive actions at national and provincial levels, often stepping beyond traditional judicial boundaries. This judicial dominance is partly attributed to the African National Congress's one-party dominance, which has led opposition parties, civil society, and citizens to rely on the judiciary to enforce constitutional compliance. The study concludes that while the separation of powers remains a constitutional ideal, in practice, judicial hegemony characterizes the South African governance landscape due to the judiciary's role as the ultimate interpreter and enforcer of constitutional supremacy.
