The Federal Regional Court of the 5th Region (TRF-5) has denied the municipality of Aracaju's request to annul a ruling that recognized a disputed area of about 20 square kilometers, representing 11% of Aracaju's total territory, as belonging to the city of São Cristóvão. This decision was made during a session held on the 11th of October, with the ruling made public on the following day. The ruling can still be appealed in higher courts, indicating that the matter may not be fully resolved.

As part of the decision, a deadline of 2024 has been set for the Brazilian Institute of Geography and Statistics (IBGE) to correct mapping and statistical data to reflect the territorial changes, which would involve readjusting the population figures for the contested area. However, no specified date has been provided for when this process will begin, leaving some uncertainty over the timeline of these adjustments.

Inquiries were made to both the city administrations of Aracaju and São Cristóvão regarding the ruling, but no responses were received by the time of the article's publication. The court's decision follows a rescisory action filed by Aracaju in 2025, aiming to contest the previous findings, highlighting ongoing territorial disputes in the region and their implications for local governance and resource allocation.
