Mixing Writs with Rights: The Implications for Public Law in Sri Lanka

Beginning around 1990, judicial interpretation transformed public law in Sri Lanka by blending writs with fundamental rights. On the one hand, the Supreme Court has defined and expanded the constitutional right ‘to equality and equal protection of the law’ by drawing on administrative law concepts of natural justice, reasonableness, legitimate expectation, the duty to provide reasons for decision-making, and proportionality. On the other hand, judges have relied on the Bill of Rights as a standard to assess the decisions of public authorities in writ matters. This relationship between the writs and the rights has had important implications for the growth of public law in Sri Lanka. There has also emerged an incipient ground of review, ‘rights-based review’, as part of the writ jurisdiction, and the ‘public trust doctrine’ in fundamental rights review. Public law has been strengthened by the growth of public interest litigation and the use of new judicial remedies. This article looks at how the writ jurisdiction and rights-based review have evolved in recent times and considers how the two remedies have been used and fused, in a country where the legal and constitutional history has taken a different trajectory to some other post-colonial societies. The article concludes by arguing that this fusion of constitutional and administrative law concepts, together with the expansion in the rules of standing and the emergence of the new concepts of public trust doctrine and fairness, have generated a more robust legal framework that can better protect constitutional rights and democratic freedoms.
