The 25 members of the Senate’s initial mandate were formally inducted at the National Assembly headquarters in Porto-Novo. The ceremony was presided over by Élisabeth Pognon, the second eldest senator present. The opening session included a ceremonial phase, featuring an inaugural address and an official group photograph, before the senators proceeded with their deliberations behind closed doors. During her address, Élisabeth Pognon underscored that the Senate’s establishment stemmed directly from the constitutional revision adopted on December 17, 2025. She articulated that this new institution serves to enhance the organization of public authorities and expressed optimism that it would contribute significantly to bolstering confidence in national institutions and fostering political stability.

The Senate’s responsibilities are distinct from those of the Constitutional Court. While the latter primarily adjudicates matters of law, the newly formed chamber exercises powers expressly conferred upon it by Article 113.1 of the Constitution. In this capacity, it is specifically mandated to safeguard national unity, reinforce the state, and uphold democracy, peace, and political truce. The Constitution further grants the Senate the authority to impose sanctions, under specified conditions, affecting the political or civic rights of certain public figures.

Furthermore, the Senate is required to provide a non-objection opinion before the promulgation of constitutional revisions, electoral laws, and legislation pertaining to political parties and their operational frameworks. This critical competence positions the Senate at the heart of the legislative process for several laws deemed essential to the functioning of national institutions. The first senatorial term comprises 25 members, aligning with constitutional provisions. Its composition includes ex-officio members and designated personalities, among whom are former leaders of public institutions and seasoned officials from the defense and security forces. With this official installation, Bénin now operates with a two-chamber Parliament, a structural configuration unprecedented since the Constitution of December 11, 1990, came into effect.
