Description of the office

Election

The president of the republic is elected for a presidential term of seven years, universal and direct suffrage, as per the 2024 Constitution. The president is eligible for re-election once, with a maximum of two consecutive terms, regardless of constitutional revisions. The 2024 Constitution reintroduced a two-term limit, replacing the unlimited re-election allowed under earlier amendments and explicitly prohibiting more than two successive mandates.
The election is conducted via a two-round majoritarian system. The candidate who obtains an absolute majority of votes expressed in the first round is elected. If no candidate achieves this, a second round is held 14 days after the proclamation of results, between the two candidates who received the most votes in the first round. The candidate with the most votes in the second round is elected. In case of withdrawal or permanent incapacity of one of the top two candidates, the next highest-ranking candidate from the first round replaces them.
Eligibility for the presidency is restricted to Gabonese citizens of either sex who:
  • are born Gabonese to at least one Gabonese parent, themselves born Gabonese;
  • hold exclusive Gabonese nationality ;
  • are aged between 35 and 70 years;
  • are married to a Gabonese spouse born to at least one Gabonese parent, themselves born Gabonese;
  • have resided in Gabon continuously for at least three years before the election;
  • can speak at least one national language;
  • enjoy full civil and political rights;
  • are certified to be in complete physical and mental well-being by a sworn medical panel designated by the bureaus of both parliamentary chambers.
The president’s spouse and descendants are ineligible to run for the presidency immediately following the president’s term. If a candidate dies or is incapacitated within the month before the first round, the Constitutional Court may postpone the election, but not beyond the incumbent president’s term end.
The Constitutional Court may extend election timelines, but the election must occur no later than the expiration of the incumbent president’s mandate. If the election is delayed beyond the current president’s term, the president remains in office until their successor is elected. The modalities for these provisions are set by organic law.
The presidential term begins on the day of the presidential oath, within eight working days after the Constitutional Court proclaimed the results, and ends after the seventh year. The election must take place no later than three months before the end of the incumbent president’s term. The incumbent president may not shorten their term to seek another mandate.
If the incumbent president runs for re-election, they cannot legislate by ordinance from the announcement of their candidacy until the election, and the National Assembly may not be dissolved. In cases of necessity, Parliament may convene in an extraordinary session.

Temporary incapacity cannot exceed forty-five days, after which it becomes permanent. In case of a vacancy or permanent incapacity of the president, as certified by the Constitutional Court upon referral by the National Assembly bureau or the Vice-President of the Government, the president of the Senate temporarily assumes presidential duties.
