OBITER DICTUM OR RATIO DECIDENDI? EXAMINING ENVIRONMENTAL RIGHTS IN CENTRE FOR POLLUTION WATCH (COPW) V NIGERIAN NATIONAL PETROLEUM CORPORATION (NNPCL)

Abstract

The Supreme Court’s decision in Centre for Oil Pollution Watch v. Nigerian National Petroleum Corporation has generated sustained debate within Nigerian environmental jurisprudence regarding the precedential status of the Court’s pronouncements on the justiciability of the right to a clean and healthy environment. This debate has been amplified by the recent English decision in Bille & Ogale, which treated Opara v. Shell as reflecting the authoritative Nigerian position and characterised the Supreme Court’s environmental rights analysis in COPW as obiter dicta, on the premise that the sole issue before the Court was locus standi. This article challenges that characterisation. Through a close doctrinal examination of the judgments in COPW, including both the lead and concurring opinions, it argues that the Supreme Court’s engagement with environmental degradation as a threat to life, health, and human survival was not incidental but constituted the indispensable reasoning upon which locus standi was expanded. By grounding standing in the enforceability of constitutional and statutory obligations under sections 33 and 20 of the 1999 Constitution, the Oil Pipelines Act, and Article 24 of the African Charter on Human and Peoples’ Rights, the Court necessarily affirmed the justiciability of environmental rights. The article concludes that these findings form part of the ratio decidendi of COPW and1 represent the current and binding position of Nigerian law on environmental rights and public interest standing.
