Dispute Over Territorial Limits Between Aracaju and São Cristóvão in Sergipe Has Dragged On for Decades
The territorial dispute in the Northeast between Aracaju and São Cristóvão, in the state of Sergipe, is gaining new developments following the court decision that requires the capital to return part of its territory to the neighboring city. The process, which has dragged on for decades, highlights issues related to the incorporation of areas without compliance with constitutional norms.

It all started with São Cristóvão’s claim that Aracaju had annexed, without public consultation, an area of approximately 20 square kilometers, including important neighborhoods such as Mosqueiro, Areia Branca, and Robalo.
The Federal Constitution of 1988 and the state constitution of Sergipe require plebiscites for these cases, but such a procedure was not respected. Thus, the neighboring municipality challenged the incorporation, initiating a lengthy legal battle.
Intense Legal Dispute: Supreme Court Reaffirms Need for Public Consultation and Aracaju Loses Rights Over Annexed Territories
In 2000, the Court of Justice of Sergipe (TJ-SE) declared the annexation of these regions in the Northeast unconstitutional. This occurred due to the lack of public consultation, a mandatory condition under paragraph 4 of article 18 of the Federal Constitution. However, the City Hall of Aracaju did not accept the decision and appealed, arguing that Constitutional Amendment 57 of 2008 validated the incorporation.
But the dispute in the heart of the Northeast continued. The Supreme Federal Court (STF) reaffirmed that, even with the 2008 amendment, public consultation was still necessary for this type of territorial change. As a result, Aracaju lost all appeals, and the case was finally adjudicated, preventing further appeals.
Master Plan of São Cristóvão Challenged by Aracaju and Proceeded to Decision in the STJ
In addition to this case, the City Hall of Aracaju also went to court to challenge the Master Plan of São Cristóvão, approved in 2020. According to Aracaju, the law included the Mosqueiro area as part of the territory of São Cristóvão in the Northeast.
However, the TJ-SE deemed this norm unconstitutional, arguing that the boundaries between the cities of the Northeast had not been clearly defined in the previous process. Now, the case moves to the Superior Court of Justice (STJ).
IBGE Has Not Commented on How the Review of the Territorial Map of Aracaju and São Cristóvão in the Northeast Will Be Conducted
For Aracaju, the disputed territory is significant. The area includes three Basic Health Units (UBSs), three municipal schools, and is served by 12 public transport lines.
Additionally, the municipality collects approximately 500 tons of urban waste monthly in these regions, highlighting the importance of this zone for local administration.
So far, the IBGE (Brazilian Institute of Geography and Statistics) has not commented on how the review of the territorial map of Aracaju and São Cristóvão will be conducted. This new mapping could redefine municipal borders, potentially bringing a solution to the historic territorial dispute in the Brazilian Northeast.

Com essa decisão abre um precedente para solicitar revisão da divisão nos municípios de Macuco e de Bom jardim no Rio de janeiro.
Uma engenheira querendo falar sobre geografia só poderia dar nisso.Se ela falasse sobre as terras sergipanas que a Bahia tomou , aí sim poderia se falar em devolver terras à Sergipe, mas , falar de municípios de um Estado como se fosse de outro Estado é trágico esse erro geográfico.Como vai devolver bairros de Aracaju para Sergipe se Aracaju é a Capital de Sergipe? Corrige logo isso para não passar mais vergonha !
“Aracaju é obrigada a devolver parte do seu território a Sergipe”. É isso mesmo? Devolver a Sergipe? Criatura zele pela sua profissão! Tenha atenção no que está fazendo! Revise sempre o texto que está preparando, sempre! “O correto é devolver parte do território ao município de São Cristóvão (Sergipe )”.
Pleonasmo é uma figura de linguagem, pelo qual é desnecessário detalhar informações. Se você leu “devolver a Sergipe”, os moradores do estado está por dentro do assunto que se assemelha a devolução do território a cidade de São Cristóvão! PLEONASMO
