The Brazilian Supreme Federal Court (STF) unanimously confirmed a ruling by Minister Dias Toffoli that annulled a decision from the Federal Court of Accounts (TCU) and reinstated a regulation from the National Agency of Waterway Transportation (Antaq) regarding the charges for Segregation and Delivery Service (SSE). This service fee is imposed by wet terminals on retroport terminals when containers are separated and made available to importers. This ruling not only affects the port sector but also sparks a significant debate on the powers of the TCU to review definitive decisions made by regulatory agencies.

The case stems from an October 7, 2025, ruling by Minister Toffoli, who reconsidered an earlier decision in favor of the Brazilian Association of Container Terminals (Abratec). The issue at hand is critical because it addresses the balance of power between regulatory agencies, which set rules and enforce standards in various sectors, and the TCU, which oversees public spending and compliance with laws. The AGU (Attorney General's Office) has also defended the TCU's stance in this matter, emphasizing an ongoing conflict over jurisdiction and regulatory oversight.

As this legal dispute unfolds, it could have broader implications for how regulatory decisions are challenged or upheld in Brazil. If the TCU's ability to overturn regulatory agency decisions is limited, it could affect the accountability mechanisms that are in place to oversee these agencies. On the flip side, a ruling empowering the TCU could engender a larger debate over regulatory flexibility and economic efficiency, particularly in sectors that rely heavily on clear and consistent regulatory guidelines, such as transportation and logistics.
