Succession, Executive Order 7, and the Duterte Name: Mayor Baste's First Months

Sebastian 'Baste' Duterte ran the city as acting mayor from mid 2025 and took his oath as Davao City's permanent mayor on January 23, 2026. He has since signed Executive Order 7 setting up an emergency socioeconomic task force, steered a P15.8 billion budget for 2026, and clashed publicly with DENR over the closure of the city's main landfill.

How succession changed Davao City leadership

Rodrigo Duterte won the 2025 Davao mayoral race while detained at The Hague, and his son Sebastian was elected vice mayor on the same ballot. With the mayor unable to serve, Baste ran the city as acting mayor from June 30, 2025. After the mayor's seat was declared permanently vacant, he took his oath as the city's 22nd mayor on January 23, 2026, with his nephew Rodrigo "Rigo" Duterte II sworn in as vice mayor. GMA News confirmed both oaths that day.

Biography and previous offices

Sebastian Zimmerman Duterte, more widely known as Baste Duterte, is the son of former president Rodrigo Duterte and Elizabeth Zimmerman. His previous offices in Davao City include vice mayor from 2019 to 2022, elected mayor beginning in 2022, vice mayor elect in the 2025 cycle, and mayor again by succession in January 2026 after Rodrigo Duterte failed to assume the mayoralty.

First executive action: Emergency task force (EO7)

In April 2026, Mayor Sebastian signed Executive Order Number 7, which created an interagency task force on emergency socioeconomic crisis response after a run of fuel price increases hit the city. The task force, which held its first meeting on April 6, 2026, covers food security, inflation, and disaster recovery. It is chaired by the mayor or city administrator and includes both city departments and national agencies.

The 2026 budget and the standoff with DENR over garbage

The city council approved a P15.8 billion budget for 2026 on November 13, 2025, about 11 percent higher than the year before. Waste turned into the bigger story. On May 20, 2026, a trash slide at the New Carmen Sanitary Landfill in Tugbok killed two people and buried homes, and DENR suspended the site two days later before ordering it permanently closed. Sebastian blamed DENR for the city's garbage backlog and, on June 4 and 5, had collected trash dumped at the DENR regional office in Lanang. Malacanang condemned the move and the DILG said it would look into his conduct.

Legal mechanism behind his return

  • The Philippine Local Government Code allows succession when an elected official fails to assume office within the prescribed period.
  • Unlike a special election, no new votes were cast. This is a rare situation where a father's non oath elevated the son.
  • Sebastian had previously been vice mayor and mayor, so the role was not new to him. But the legal path was unusual.

What EO7 actually does

  • The task force includes Davao City Hall departments like Social Welfare, Health, and Agriculture, plus national agencies such as DSWD, DOH, and DA.
  • Its mandate covers emergency socioeconomic crises: price surges, supply chain breaks, and post disaster economic shocks.
  • This shifts focus away from the family's traditional security first image toward economic resilience and crisis management.

Position among Duterte family members

  • His brother Paolo Duterte remains in the House of Representatives. His sister Sara Duterte faces an impeachment crisis as vice president.
  • His father Rodrigo Duterte is entangled in an ICC case, creating a political vacuum that Baste's local governance now helps fill.
  • No verified record supports 2028 national ambitions for Sebastian. His public actions center on Davao City ordinances and task forces.

Often overlooked details

  • The January 23 oath was administered under succession, not a fresh mandate. That distinction gets lost in many headlines.
  • EO7's socioeconomic angle is a departure from Rodrigo Duterte's crime focused executive orders during his mayoral years.
  • Baste's previous mayoral term before 2025 means he inherited policy continuity, not a from scratch administration.
  • Searches for 'Sebastian Duterte previous offices' should distinguish his elected vice mayor term, elected mayor term, and 2026 succession back into the mayor's office.
