Oiapoque mayoral election 2026 set for 12 April

The Tribunal Regional Eleitoral of Amapá has confirmed that the Oiapoque mayoral election 2026 will take place on 12 April 2026, after the regional court annulled the 2024 results and removed the incumbent mayor and deputy from office. The decision follows a unanimous ruling that found abuse of economic and political power during the previous municipal contest.

Until the supplementary poll is held, the city will be administered by Pedro Guido, president of the Municipal Chamber, who took office as interim mayor on 16 December. The court also ordered the immediate loss of the mandates and the annulment of votes cast for the ousted ticket.

Oiapoque mayoral election 2026 key dates

The TRE-AP and the Superior Electoral Court have published a timetable for the supplementary election. Voters and parties should note the deadlines for voter registration and changes of electoral domicile, party conventions, registration of candidacies, campaign and advertising rules, and the judgement of electoral accounts. The diplomas for the elected candidate are expected to be issued by 4 May 2026.

The process originated in the 4th Electoral Zone, which identified irregularities in the 2024 ballot, and the verdict was ratified by the full panel of the TRE-AP. Appeals filed by the former mayor and vice were rejected by regional judges and the Superior Electoral Court declined to entertain a special appeal, making the decision final and enforceable.

Federal police action in 2024, which included the arrest of four people in connection with alleged vote buying, was referenced in court materials. The findings contributed to the tribunal’s assessment of abuse of power and the integrity concerns that prompted the supplementary election.

Administration and oversight until the vote

As interim mayor, Mr Guido will oversee municipal services and coordinate with electoral authorities to ensure the conditions for a lawful poll. The TRE-AP indicated that it will provide details to political parties and the public on registration procedures, campaign periods and deadlines for presenting and judging electoral accounts.

Local political actors and civic organisations are expected to monitor the campaign closely. The supplementary election will determine who completes the municipal term and will be followed by the formal issuance of diplomas for the successful candidate. The court’s expedited schedule aims to restore duly elected municipal leadership quickly while preserving due process.

Analysts say the decision underscores the regional judiciary’s role in upholding electoral norms and deterring improper influence in small municipalities. For residents of Oiapoque, the coming months will be decisive as parties prepare their slates and voters register or update their electoral domicile in advance of the April poll.
