摘要:Civil society organizations have played a pivotal role in democratization process in Nigeria since the advent of the Fourth Republic. They have greatly helped in the success of the 2015 and 2019 General Elections through pre-election, during election, and in post-election monitoring and advocacy. This article, therefore, examined the role of the Nigerian Civil Society Situation Room (NCSSR) in improving the election in Nigeria during the 2015 and 2019 General Elections. While many civil societies flourished recently in Nigeria, their role toward democratization and facilitating credible election remain insignificant until in the 2015 and 2019 General Elections where their activities helped immensely the process of a credible election. A Civil Society as the Third Tier of Government framework was adopted as a theoretical explanation of the context of the work. The research used a qualitative case study method of data collection where informants consisting of members of NCSSR, Independent National Electoral Commission (INEC), and academicians were selected for the interview and Focus Group Discussion. The total number selected was 16 from the three identified categories. The research discovered that the NCSSR aided the process and fairness of the 2015 and 2019 General Elections through proper monitoring, civic voter education, active collaboration with electoral body (INEC), and collaboration with international donor agencies through what they called “Civil Society Situation Room” which consist of more than 60 registered civil societies. The research recommends that civil societies should be empowered with constitutional backing and independent funding to enable them carry out their responsibilities adequately. Also, the article recommends that the electoral body (INEC) should liaise more and cooperate with civil societies to enable them conduct good and credible elections in future.
