ABSTRACT
The doctrine of separation of powers is a fundamental principle of governance in Nigeria, designed to ensure that each arm of government (legislative, executive, and judicial) operates within its constitutional boundaries. However, despite its constitutional provisions, the doctrine has been criticized for being more of a myth than a reality in Nigeria. This study aims to investigate the challenges and limitations of the doctrine of separation of powers in Nigeria and provide recommendations for strengthening its effectiveness in promoting national development. The study employs a qualitative research approach, utilizing a combination of primary and secondary data sources. Primary data is collected through interviews with key stakeholders, including government officials, legal experts, and civil society representatives. Secondary data is gathered from relevant legal documents, academic literature, and media reports. The findings of the study reveal that the doctrine of separation of powers in Nigeria is plagued by several challenges, including executive dominance, judicial dependence, and legislative weakness. These challenges have significant implications for national development, including the erosion of the rule of law, lack of accountability, and instability in governance. To address these challenges, the study provides several recommendations, including the need for a constitutional review to strengthen the doctrine, the protection of judicial independence, and the enhancement of legislative capacity. The study also highlights the importance of promoting cooperation and partnership between the different arms of government to ensure the effective implementation of the doctrine. The study contributes to the existing body of knowledge on the doctrine of separation of powers in Nigeria and provides a framework for understanding its implications for national development. The findings and recommendations of the study are relevant for policymakers, legal scholars, and civil society organizations interested in promoting good governance and sustainable development in Nigeria.
