INVESTIGATING THE SENATE LEADERSHIP FINANCIAL MISAPPROPRIATION PROBE: THE PROFOUND CHALLENGE OF EFCC'S ROLE IN ENSURING ACCOUNTABILITY AND JUSTICE IN GOVERNANCE

This study interrogates the pervasive phenomenon of financial misappropriation and governance failure within Nigeria’s legislative architecture, with particular emphasis on Senate leadership and the broader institutional complicity that undermines public accountability. The main objective of the study is to critically examine the patterns, causes, and consequences of financial abuse in public office, while advancing pragmatic recommendations for strengthening transparency, fiscal discipline, and institutional integrity. The study adopts a mixed-methods research design, integrating both qualitative and quantitative approaches to ensure analytical depth and empirical robustness. Data were sourced from primary and secondary materials, including structured questionnaires, key informant interviews, government reports, legislative records, audit documents, publications from international organisations, and reputable media outlets. The tools employed for data analysis include descriptive statistics, inferential analysis, and thematic content analysis, facilitated through the Statistical Package for the Social Sciences. The Taro Yamane mathematical formula was applied to determine an appropriate sample size, ensuring representativeness and statistical validity. The study further adopts strategic analytical techniques such as triangulation, comparative analysis, and institutional critique to enhance the reliability of findings. Anchored on the Institutional Theory and Public Choice Theory, the research provides a theoretical framework for understanding the interplay between personal interests, systemic weaknesses, and governance outcomes. Findings reveal entrenched patterns of financial mismanagement, weak oversight mechanisms, legislative impunity, and the ineffective role of critical institutions such as anti-corruption agencies and the judiciary in enforcing accountability. The study establishes that the persistence of these anomalies is largely attributable to systemic opacity, political interference, and inadequate enforcement of legal frameworks. Consequently, the study recommends comprehensive institutional reforms, strengthened legislative oversight, enhanced transparency mechanisms, judicial independence, and the adoption of stricter sanctions against financial misconduct. The study unequivocally asserts that without decisive and uncompromising reforms, the integrity of Nigeria’s governance system will remain fundamentally compromised, thereby perpetuating a cycle of economic stagnation and public distrust.
