On September 7, 2026, the Senegalese Constitutional Council, known as the Conseil constitutionnel, issued its decision n° 8/C/26. This significant ruling addressed an organic law that proposed modifications to Article 118 of the National Assembly's Internal Regulations, often referred to as the Règlement intérieur AN. The review process was initiated following a formal request from the President of the Republic, underscoring the executive's role in seeking constitutional oversight of legislative procedures.

The Council's verdict represented a nuanced outcome. While a substantial portion of the proposed text received validation, affirming its constitutional compliance, several specific provisions were simultaneously censored. This partial invalidation highlights the Council's active role in ensuring that legislative bodies operate within established constitutional boundaries, even when defining their own internal operational guidelines.

The intervention of the Conseil constitutionnel in matters pertaining to the Règlement intérieur AN is a cornerstone of droit constitutionnel Sénégal. As the ultimate arbiter of constitutional legality, the Council is tasked with scrutinizing laws, particularly organic laws, to ensure their conformity with the nation's foundational legal principles. An organic law, such as the one under review, holds a higher hierarchical position than ordinary laws and often defines the organization and functioning of public powers, including the Assemblée nationale Sénégal.

This specific decision, Sénégal décision 8/C/26, reaffirms the Council's mandate to review legislative texts prior to their promulgation, especially when they touch upon the fundamental structure and operational rules of a key state institution. The loi organique Sénégal in question sought to amend the internal rules governing the legislative body, making it a prime candidate for such a constitutional examination.

In its detailed pronouncement, the Conseil constitutionnel affirmed the constitutionality of the core elements within the organic law. This validation means that the essential framework for the National Assembly's revised internal operations, as outlined in the majority of the text, can proceed. However, the Council did not grant blanket approval. It specifically identified and censored several provisions that were deemed incompatible with the Constitution.

Crucially, these invalidated sections were particularly related to the perte mandat parlementaire Sénégal, addressing circumstances under which a member of parliament could lose their seat. By striking down these specific clauses, the Council has set clear limits on the National Assembly's ability to define the conditions for the forfeiture of a parliamentary mandate, reinforcing constitutional safeguards for elected representatives.

This ruling carries significant weight for the governance and operational autonomy of the Assemblée nationale Sénégal. By partially censoring the proposed amendments to the Règlement intérieur AN, the Conseil constitutionnel has underscored the principle that even the internal rules of a legislative body must adhere strictly to the overarching constitutional framework. This decision clarifies the constitutional boundaries for the National Assembly's internal operations in Senegal, particularly regarding the loss of parliamentary mandate.

For legal professionals advising parliamentarians or involved in constitutional challenges, this judgment necessitates a thorough review of the specific provisions that were both validated and censored. It provides an updated legal framework concerning the internal functioning of the legislative branch and the conditions for the perte mandat parlementaire Sénégal, thereby shaping future legislative practice and constitutional interpretation in Senegal.

This decision clarifies the constitutional boundaries for the National Assembly's internal operations in Senegal, particularly regarding the loss of parliamentary mandate. Lawyers advising parliamentarians or involved in constitutional challenges must review the specific provisions validated and censored to understand the updated legal framework.
