In Akoko-Edo Federal Constituency, ₦65 million was spent on a road that residents could dismantle with their bare hands after construction. Contractors were paid, the project was recorded as completed, yet no citizen had a safe or effective channel to trigger government action. This reflects a broader national pattern as the Bureau of Public Procurement documented over 11,000 abandoned federal projects worth ₦12 trillion. In 2023, Afrobarometer further reports that only 24% of Nigerians trust the federal government. Together, these point to a systemic breakdown in procurement accountability and enforcement in Nigeria. The Public Procurement Act 2007 established the Bureau of Public Procurement (BPP) with mandates for contract certification, audits, and citizen complaints under Section 38. However, this system was designed for formal complainants, not ordinary citizens and it has no automatic enforcement trigger linked to citizen reports. This paper evaluates three policy options: Complaint Access & Process Enhancement (CAPE), Citizen Oversight & Reporting Accountability (CORA), and Supplier Compliance & Oversight Rating (SCOR). CORA is recommended as the most feasible option. It is a regulatory upgrade under Section 4 of the Public Procurement Act, requiring no new legislation. It also enables anonymous reporting through USSD, mobile, and web platforms in five Nigerian languages. When reports reach a set threshold, they trigger a Bureau of Public Procurement audit, with findings published within 30 days. By linking citizen reporting to mandatory action, CORA is designed to rebuild institutional trust between citizens and Nigeria's public procurement institutions.
