EXECUTIVE DISCRETION AND REGULATORY AUTONOMY UNDER NIGERIA'S PETROLEUM INDUSTRY ACT 2021 WITH LESSONS FROM THE UNITED KINGDOM, UNITED STATES, AND GHANA

The Petroleum Industry Act (PIA) 2021 was enacted to address long-standing governance issues in Nigeria's petroleum sector, including regulatory fragmentation, institutional inefficiency, weak accountability structures, and ongoing uncertainty in the administration of upstream petroleum resources. Despite the significance of these reforms, questions persist about how well the Act balances executive control and regulatory autonomy. This paper examines the relationship between executive discretion and regulatory autonomy under the PIA 2021, focusing on the governance framework of Nigeria’s upstream petroleum sector. It addresses the ongoing debate over the concentration of ministerial powers and its implications for effective petroleum governance. The study adopts a doctrinal and comparative legal methodology, analysing the relevant provisions of the PIA, associated regulatory instruments, and selected scholarly literature, and is complemented by a comparative examination of petroleum governance frameworks in the United Kingdom, the United States, and Ghana. The study finds that although the PIA introduced significant institutional reforms through the establishment of the Nigerian Upstream Petroleum Regulatory Commission (NUPRC), ministerial authority over policy supervision, licensing administration, and institutional oversight continues to overlap with regulatory functions, thereby limiting the regulator's operational independence. The paper also indicates that the Act's governance system reflects a qualified, rather than complete, regulatory autonomy. Comparative analysis shows that, despite their institutional differences, the United Kingdom, the United States, and Ghana have clearer distinctions between policymaking and regulation, stronger accountability mechanisms, and greater protection for regulators from executive interference. The article concludes that the efficacy of the PIA depends not only on legislative change but also on the degree of institutional autonomy granted to regulatory agencies. It advises lowering ministerial involvement in regulatory administration, increasing NUPRC independence, improving licensing transparency, and clarifying institutional boundaries within Nigeria's petroleum governance system.
