The Application of the Precautionary Principle in Nigerian Petroleum Environmental Law: A Critical Analysis

This study critically analyses the application of the precautionary principle in Nigerian petroleum environmental law, assessing the extent to which this foundational environmental law norm shapes regulatory decisions, judicial outcomes, and corporate conduct in the sector. The precautionary principle, which requires preventive action under scientific uncertainty, is recognised in international environmental instruments to which Nigeria is a signatory, including the Rio Declaration on Environment and Development. Using a doctrinal analytical methodology, the research examines how Nigerian courts, the NUPRC, and the Federal Ministry of Environment have invoked or failed to invoke the precautionary principle in thirty petroleum-related decisions and regulatory guidelines between 2015 and 2024. Comparative analysis draws on the application of the principle in South African and United Kingdom environmental jurisprudence. The study identifies a persistent judicial reluctance to apply the precautionary principle proactively, partly attributable to weak legislative codification of the principle in Nigerian petroleum law. The research argues for the explicit statutory embedding of the precautionary principle in the PIA 2021's environmental provisions and EGASPIN through legislative amendment, and discusses how such reform could reshape regulatory practice.
