Abstract: It is no longer news that corruption has in absolute term undermined development efforts of successive administrations in Nigeria, hence the low level of development in every critical sector of her economy. This study was undertaken to critically examine the activities of the anti-graft agency (EFCC) in the fight against corruption in Nigeria (2007-2017). To realize this lofty objective, content analytical method was adopted as data were predominantly generated from the secondary sources. The study adopted structural functionalism theory expounded by Talcott Parson in the 1930’s. The study revealed among other things that the commission has continued to contend with outdated criminal and penal codes which are out of tune with present criminal realities in the country and that the conventional courts have always delayed trials of corrupt cases brought before them by the commission and that EFCC has remained a tool in the hands of successive regimes to witch-hunt their perceived and imagined enemies. It is therefore, against the above obvious revelations that we recommended as follows among others that the commission should be truly made independent so as to carry out independent actions in the discharge of its constitutional mandates that the criminal and penal code be reviewed to be in accord with minimum global best practices and that a special court to try corruption and other related cases should be set up to encourage speedy justice system. These measures if judiciously implemented are believed to assist the commission to win the fight against corruption in the country.
