This document discusses successes and failures of freedom of information laws from a global perspective. It finds that while FOI laws have increased government accountability in some countries by up to 20 years after enactment, responsiveness to information requests has remained mixed, with less than half of requests being fully successful. An ideal FOI law has broad coverage of information, narrow exemptions subject to public interest overrides, an independent implementing agency, timely responses, low costs, and penalties for noncompliance. Mexico is highlighted as having a relatively strong FOI law due to factors like its broad public interest test and capable independent oversight agency.
