Summary The SUMMA database created by the Center for Justice and International Law (CEJIL1, by its acronym in Spanish) grants free access to every active or closed case opened in the last decades by the Commission and the Interamerican Court of Human Rights, the bodies of the Interamerican Human Rights System. Understanding Court judgements and resolutions about human rights violations in Latin America is essential for activists. The system provides quick and intuitive access to a lot of case law issued by the Court and the Commission. Also, it allows to look up every relevant document connected to a case and filter documents by typology, country, case status, signatory judge, etc. The database was developed using UWAZI, the open source platform created by HURIDOCS to organize, analyze and share collections of documents. The database described in this document is constantly updated with new decisions made by the Court and the Commission and can be accessed in the following link: This case study addresses the methodological considerations that were taken into account for enhancing access to judicial information. The guide is, thus, a kickoff to think how to develop a data model and how information should be registered and structured to facilitate its retrieval by users, as well as to provide aggregated information regarding cases, all this accurately and reliably. Needs that motivated the creation of SUMMA CEJIL works with a network of human rights practitioners in the legal and academic fields as well as national and international human rights organizations. For these practitioners and other human rights defenders, the access to cases and decisions made by the Court and the Commission is a constant need. Understanding case 1 CEJIL works on the defense and promotion of human rights in Latin America harnessing the Interamerican Human Rights System and other international mechanisms of protection. Taking advantage of these instruments, the Center seeks to reduce inequality and exclusion in the region, pursuit justice in cases of human rights violations, strengthen democracy and public institutions and improve the efficacy of the Interamerican Human Rights System. 2
