Sénégal Conseil Constitutionnel: Invalide Loi Organique Finances

• The Sénégal Conseil constitutionnel invalidated organic law n° 38/2026 on October 15, 2026, which aimed to modify finance laws.
• The decision, n° 10/C/2026 Sénégal, found that the Assemblée nationale violated a substantial formality during the law's adoption.
• The violation stemmed from the Assemblée's failure to adhere to Article 82 alinéa 4 Constitution Sénégal regarding government amendments.
• Despite a formal request from the government to vote on the text with only its amendments, the Assemblée rejected these amendments separately before adopting the main bill.
• As a result, the loi organique 38/2026 invalidée is deemed unconstitutional and will not enter into force, requiring continued adherence to the existing finance law framework.

This non-compliance, the Council ruled, constituted a "violation formalité substantielle loi organique," fundamentally undermining the adoption procedure and invalidating the loi organique 38/2026 invalidée.

The Conseil constitutionnel of Sénégal recently issued a landmark decision, n° 10/C/2026, on October 15, 2026, declaring organic law n° 38/2026 unconstitutional. This ruling effectively means the Sénégal Conseil constitutionnel invalide loi organique finances, specifically a proposed amendment to the existing organic law n° 2020-07 of February 26, 2020, which governs finance laws. The high court found that the legislative process undertaken by the Assemblée nationale on October 1, 2026, to adopt this measure contained a substantial procedural irregularity.

The President of the Republic initiated the challenge, submitting an urgent request to the Council on October 8, 2026. This petition, recorded under the same reference number 10/C/2026, sought a declaration that the adoption procedure for the organic law was not compliant with the Constitution, and consequently, its invalidation. The Council, asserting its jurisdiction under Article 92 of the Constitution, deemed the referral admissible, noting that Article 74 permits the President to file such a request within six clear days following the transmission of a definitively adopted law. A formal notification regarding the challenge was dispatched to the President of the Assemblée nationale on October 9.

The core of the President's argument centered on the Assemblée nationale's handling of government-proposed amendments during the legislative debate. The President contended that the Assemblée had adopted the law without incorporating two specific amendments put forward by the government, and crucially, without rejecting the entire legislative text. The government had explicitly requested that its amendments be given "exclusive consideration," citing the provisions of article 82 alinéa 4 Constitution Sénégal.

To substantiate this claim, the President provided compelling evidence, including two USB drives containing video footage of the plenary session and a bailiff's report dated October 8, 2026. This report meticulously documented the proceedings, reproducing a statement from the Minister of Justice, representing the government, who formally requested a single vote on the bill, retaining only the amendments proposed or accepted by the government. The same report confirmed that, despite this formal request, the government's amendments were ultimately rejected by the Assemblée nationale. This sequence of events highlighted a critical deviation from the prescribed procédure adoption loi Assemblée nationale Sénégal.

In its deliberation, the Conseil constitutionnel meticulously reviewed the constitutional mandate outlined in Article 82, alinéa 4. This article stipulates that if the government makes such a request, the Assemblée nationale must cast a single vote on all or part of the text under discussion, incorporating only those amendments proposed or accepted by the government. The Council concluded that the Assemblée had two permissible courses of action: either to adopt the bill with only the government's amendments (and any deputy amendments accepted by the President), or to reject the entire text.

However, the Council observed that the government's amendments were voted upon separately from the main bill and subsequently rejected, notwithstanding the government's explicit demand. Following this, the single article of the proposed law was voted on and adopted without these crucial amendments being integrated. The Conseil constitutionnel therefore determined that the Assemblée nationale had failed to adhere to Article 82, alinéa 4, of the Constitution. This non-compliance, the Council ruled, constituted a "violation formalité substantielle loi organique," fundamentally undermining the adoption procedure and invalidating the loi organique 38/2026 invalidée. The decision's first article explicitly states the law is "contrary to the Constitution," with the second article mandating its publication in the Official Journal. The ruling was deliberated by a quorum of four members, including President Ousmane Diagne and Vice-President Aminata Ly Ndiaye, underscoring the gravity of the procedural breach.

Lawyers and compliance officers in Senegal should note this decision as a critical precedent for challenging the procedural validity of laws, particularly regarding the National Assembly's adherence to constitutional provisions on government amendments during legislative adoption. It underscores the strict interpretation of 'formalité substantielle' and confirms that the proposed modifications to the finance law (n° 2020-07) are not in force, requiring continued adherence to the existing framework.
