Assessing Freedom of Information in Latin America a Decade Later: Illuminating a Transparency Causal Mechanism

More than 100 freedom of information (FOI) laws have been enacted worldwide, nearly half within the last 10 years. Yet these cross‐domain, lynchpin transparency measures have received little scholarly attention. This article assesses the 16 FOI measures adopted across Latin America. Is secrecy being surrendered in a region marked by legacies of opacity? Why are some laws fulfilling their de jure potential in practice while others are not? This article aims to achieve 3 general objectives. It analyzes the de jure and de facto strength of Latin American FOI regimes; it exposes critical data‐based and methodological challenges in evaluating and comparing transparency laws; and it illustrates how a causal mechanism, driven by the interactive dynamics of legislative balances of power and cabinet compositions, has had a determinate influence in shaping the strength of FOI regimes from adoption to implementation and reform.
