On February 27, 2026, Supreme Court Justice Flávio Dino ordered the federal government and the National Congress to explain, within ten days, the imposition of secrecy on public documents and information.

The measure was taken in the context of an action that questions the repeated application of secrecy to information of public interest, the Claim of Non-compliance with Fundamental Precept 1.308 requested by the Novo party. The action is based on a survey by Transparência Brasil which points to inconsistencies in the control of information classified as secret in the federal government by the Joint Information Revaluation Commission (CMRI).

The study found that the database of the CMRI, the body responsible for overseeing the application of the Law on Access to Information (LAI) in the federal executive, registers 1,971 fewer secrets than the total recorded in the lists published by ministries and other federal bodies. Cross-referencing the databases also revealed discrepancies between official records, including classified information that only appears in one of the systems analyzed.

According to the Transparência Brasil study, these inconsistencies indicate structural flaws in the monitoring of the use of secrecy. Among the problems identified are the limitations and technological outdatedness of the system used to record classifications and the lack of mechanisms to ensure that all federal agencies correctly inform decisions about why they restrict access to public documents.

The data gathered in the study reinforces the need to improve control and transparency mechanisms over the classification of information in the public sector. The lack of systematic monitoring makes it difficult to assess the extent of the use of secrecy in the country and to verify whether restrictions follow the criteria established by the Access to Information Law.
