Prior to 2007, Nigerian public procurement was not formally regulated, in the sense that there was no law governing procurement at the federal or state level. This changed with the enactment in 2007 of the Public Procurement Act. This act was passed on the recommendation of the World Bank, which had conducted a country procurement assessment report on Nigeria in 1999. This article seeks to determine whether the Public Procurement Act meets the requirements of international best practice. The article examines what may be regarded as international best practice in the public procurement context and analyses whether the Nigerian Public Procurement Act contains provisions which accord with this practice. It also considers what factors are limiting the adoption of international best practice in the Nigerian context.
