In a landmark ruling made public this Thursday, July 9, 2026, the Constitutional Council of Sénégal struck down the constitutional revision law that had been passed by the National Assembly in late June. Acting on an urgent referral from President Bassirou Diomaye Faye, the esteemed “Sages” of the Council determined that the adoption procedure for law n°18/2026 contravened the nation’s Fundamental Law. This dramatic legal development brings to light significant procedural disagreements at the highest levels of government, while simultaneously affirming the crucial role of the high court as a constitutional guardian.
An unprecedented presidential referral on procedural grounds
The legislative text, which aimed for a significant overhaul of the institutional framework—including a rebalancing of powers between the executive and legislative branches, a prohibition on the head of state leading a political party, and the establishment of a Constitutional Court—had been adopted on June 29, 2026, by the National Assembly.
However, in an unusual move for a bill initially championed by the ruling coalition, President Bassirou Diomaye Faye himself lodged an appeal with the Constitutional Council on July 6. Filed under an urgent procedure by his legal advisors, this appeal did not challenge the substance of the proposed reforms but specifically sought to establish that the parliamentary adoption process had failed to meet constitutional requirements. To support his referral, the presidency submitted a comprehensive dossier containing debate minutes, rejected government amendments, and audio and video recordings of the parliamentary sessions.
Financial and procedural grounds for the Council’s rejection
The Constitutional Council declared the constitutional law non-compliant based on stringent legal arguments, first dismissing the National Assembly President’s objection to the Council’s jurisdiction in constitutional matters.
Two primary reasons, enshrined in Article 82 of the Senegalese Constitution, underpinned this invalidation:
- Creation of public charges without compensation (Paragraph 2): The Sages reiterated the fundamental principle that proposals or amendments by deputies are inadmissible if their adoption leads to a reduction in public resources or an increase in public expenditure, unless accompanied by proposals for compensatory revenue. The text examined by the deputies was found to violate this strict financial rule.
- Refusal to consider Executive objections (Paragraph 4): The high court observed that the National Assembly had refused to adjourn the debate or reject problematic provisions at the express request of the government, thereby infringing upon the executive’s prerogatives in the legislative process.
« This violation of the texts affects the validity of the revision law itself, » stated the Constitutional Council’s decision, leading to its outright annulment before any promulgation or submission to a referendum.
A judicial arbitration at the heart of the political debate
This verdict from the Sages marks a pivotal moment in Sénégal’s 2026 political calendar. While supporters of the ruling party view it as a technical halt that will necessitate a more rigorous re-drafting of the proposal, the opposition celebrates it as a victory for the rule of law against legislative haste.
Far from weakening institutions, this decision underscores the vibrancy and independence of constitutional justice in Sénégal, demonstrating its capacity to arbitrate significant disputes between the presidency and Parliament.
By invalidating law n° 18/2026, the Constitutional Council reaffirms that even the most ambitious reforms must rigorously adhere to the procedures stipulated by the Fundamental Charter. For President Bassirou Diomaye Faye and his government, the immediate task is to re-evaluate their legislative strategy to successfully implement the reforms promised to the Senegalese people, whether through a new, amended text or via a direct popular referendum.
