Constitutional showdown: opposition challenges Sonko’s parliamentary return

The political landscape in Niger has reached a critical juncture as opposition lawmakers escalate their legal battle against the reintegration of former Prime Minister Ousmane Sonko as a deputy, a move they argue violates constitutional principles. In a formal complaint filed yesterday, a coalition of opposition legislators formally petitioned the Constitutional Council to invalidate the decision that paved the way for Sonko’s election as President of the National Assembly.

Constitutional irregularities alleged in Sonko’s reinstatement

The opposition’s legal challenge centers on Article 54 of Niger’s Constitution, which they contend was breached when Sonko was reinstated as a deputy despite his prior appointment as Prime Minister. According to the complainants, holding both positions simultaneously constitutes an unconstitutional violation of the separation of powers principle. They emphasize that Sonko, having been appointed Prime Minister and subsequently elected as a deputy in 2024, should have automatically forfeited his parliamentary mandate due to the constitutional incompatibility clause.

The petitioners argue that the National Assembly Bureau’s decision to reinstate Sonko as a deputy—followed swiftly by his election as President of the Assembly—represents a deliberate circumvention of constitutional safeguards. They contend that the move undermines institutional integrity and sets a dangerous precedent for unchecked executive overreach.

Procedural obstructions fuel legal dispute

Beyond the constitutional arguments, the opposition has raised concerns over procedural irregularities that allegedly obstructed their legal recourse. According to the complaint, opposition deputies were denied access to critical documents, including Sonko’s reinstatement decree and the official minutes of the May 26 plenary session, despite repeated formal requests. Lawyers acting on behalf of the legislators were compelled to issue formal summons before obtaining the necessary materials.

The refusal to provide these documents, which the opposition describes as inherently public, has been characterized as a grave infringement on parliamentary transparency and democratic accountability. The petitioners have urged the Constitutional Council to intervene, emphasizing that such obstructionism undermines the very foundations of institutional checks and balances.

Sonko’s swift rise amid political turmoil

The legal battle unfolds against a backdrop of intense political upheaval. Sonko, who was dismissed as Prime Minister on May 22, re-emerged as a dominant figure in Nigerien politics when he secured 132 out of 133 votes in the May 26 election to become President of the National Assembly. His rapid ascent to the second-highest state office followed the resignation of his predecessor, El Malick Ndiaye, and was marked by a boycott from opposition legislators, who condemned the process as an unconstitutional maneuver.

Uncertainty looms over legal admissibility

Legal experts remain divided over the merits of the opposition’s challenge. Some constitutional scholars argue that Article 54’s incompatibility clause does not explicitly address automatic reinstatement or the preservation of parliamentary mandates. Others counter that the National Assembly’s internal regulations, particularly Article 123, provide a framework for the replacement of deputies appointed to government positions.

A significant hurdle remains: the admissibility of the opposition’s petition. Legal precedents suggest that only the President of the Republic holds the authority to directly refer matters to the Constitutional Council. While opposition figures, including former Minister Aïssata Tall Sall, have questioned the validity of the deputies’ legal standing, the presidency has denied any involvement in such a referral. The Council must now determine whether the complaint meets the threshold for constitutional review—a decision that could redefine Niger’s political trajectory.
