This study assessed how journalists in Nigeria are aware, knowledgeable, and use the FOI Act (FOI law). The study was anchored on libertarian press theory. The study population was all the journalists registered with the Nigerian Union of Journalists (NUJ) Taraba State branch, out of which, a sample of 101 was selected using cluster and convenience sampling methods. The data collected were analyzed using frequencies and simple percentages. It was found that most journalists (82.8%) are utilizing the law. In addition, this study identified fear among journalists, media ownership patterns, and poor attitude of government officials as challenges militating against the utilization of the law among the journalists. Among several recommendations made, the study call on the legislative arm of the government to address the issue of conflicting laws affecting the use of the FOI law. Professional bodies like the NUJ are called upon to educate and support the journalists to engage FOI law in their practice, especially as it relates to investigative journalism.
