A research project by the Foundation of Getulio Vargas (FGV) evaluated the responses to information requests from the Senate, House of Representatives (Câmara dos Deputados), and municipal governing bodies. Overall the response rate was only 66%, leaving the legislative branch with the poorest evaluation in the study that tested the effectiveness of the Access to Information Law in different areas of the government. The legislation was introduced in 2011 and signed into law by the president in 2012.
Researchers from the Public Transparency program at the University Fundação Getulio Vargas (FGV) analyzed the information access platforms from the governments of all 27 Brazilian states. The results indicated that the implementation of the Access to Information Law is still far from ideal.
