The article aims to evaluate the completeness and the functioning of the courts’ electronic databases of judicial decisions. Assuming that access to information from public institutions is necessary, courts have the duty to make their decisions public and easily accessible to citizens. On this basis, electronic databases of judicial decisions are currently the most adequate means for this task. In order to access the courts’ transparency in publicizing their case law, the article presents two evaluation matrices (the basic matrix and the boolean operators matrix), stemming from the premise that the courts’ electronic databases should contain the complete content of all rendered decisions, and should supply adequate research tools for online research, covering the entire decision. To illustrate the use of the presented matrices, they are applied to assess the electronic databases of the Brazilian Federal Supreme Court and the Brazilian Superior Court of Justice.
