The Constitutional Council of Senegal delivered a landmark ruling on Thursday, July 9, 2026, striking down the constitutional amendment bill passed by the National Assembly in late June. Acting on an urgent petition from President Bassirou Diomaye Faye, the high court ruled that the legislative process behind Law No. 18/2026 violated the country’s foundational legal framework. This unprecedented legal intervention has laid bare procedural fractures at the highest echelons of government while underscoring the Council’s pivotal role as a guardian of constitutional integrity.
Unprecedented executive intervention in legislative matters
The controversial bill, which sought sweeping institutional changes—including rebalancing executive and legislative authority, prohibiting the president from leading a political party, and establishing a new Constitutional Court—was overwhelmingly approved by the National Assembly on June 29, 2026. Yet in a striking departure from conventional practice, particularly given the ruling coalition’s backing of the reforms, President Faye filed an emergency appeal with the Council on July 6. The petition did not contest the substance of the reforms but instead focused exclusively on procedural violations in the bill’s passage through parliament. To substantiate their claim, the presidency submitted a meticulously compiled dossier, including session transcripts, rejected government amendments, and audiovisual recordings of the legislative debates.
Financial and procedural grounds for annulment
In its ruling, the Council dismissed preliminary objections raised by the Assembly president, who argued that the judicial body lacked jurisdiction over constitutional matters. The decision hinged on two decisive violations of Senegal’s Constitution, Article 82:
- Unfunded mandate (Clause 2): The Council reaffirmed that any legislative proposal or amendment that increases public expenditure or imposes additional financial burdens without compensatory revenue measures is constitutionally inadmissible. The bill in question was found to breach this principle by introducing new public offices without securing the necessary budgetary provisions.
- Exclusion of executive objections (Clause 4): The high court observed that the National Assembly had disregarded the government’s repeated requests to adjourn debate or remove contentious provisions, thereby infringing on the executive’s constitutional prerogatives during the legislative process.
The Council concluded that these procedural breaches fundamentally undermined the validity of the amendment law, resulting in its immediate annulment before any possibility of promulgation or submission to a public referendum.
Judicial ruling reshapes the political landscape
This landmark decision has sent ripples through Senegal’s 2026 political calendar. While supporters of the ruling party view the ruling as a technical setback necessitating a more methodical reworking of the reforms, opposition factions have hailed it as a triumph of legal principle over legislative haste. Far from weakening the state’s institutions, the verdict underscores the robustness and independence of Senegal’s constitutional justice system—capable of adjudicating even the most contentious disputes between the presidency and parliament.
By striking down Law No. 18/2026, the Constitutional Council has sent a clear message: no matter how far-reaching or transformative a reform agenda may be, it must strictly adhere to the procedural safeguards enshrined in the Constitution. For President Bassirou Diomaye Faye and his administration, the path forward now demands a strategic reassessment—whether through the drafting of a revised bill or by pursuing the reforms directly via a national referendum.
