Gabon’s Constitutional Court has rejected a legal challenge filed by Ariel-Éloi Iwangou-Iwangou, founding president of the Republican and Democratic Party (PRD), concerning the government’s procedure for amending the law governing political parties.

The decision, issued on October 12 and reported on October 15, 2026, centred on the government’s September 18 deliberation concerning proposed changes to Law No. 016/2025 of June 27, 2025, which regulates political parties in Gabon.

Iwangou-Iwangou had argued that the amendment process relied on a version of the legislation that had been withdrawn from the Official Gazette following reported material errors. He asked the court to declare the procedure irregular and annul the government’s decision.

However, the Constitutional Court ruled that the government deliberation being challenged was not among the acts it was constitutionally authorised to review. It also referred to the constitutional deadline for challenging promulgated laws.

The court’s decision was procedural rather than a ruling on the substance of the dispute. It did not determine whether the successive versions of the political parties law were legally consistent.

The case comes amid wider discussions about political regulation and institutional accountability in Gabon. The ruling leaves the substantive questions raised by the PRD leader unresolved, while highlighting the constitutional limits and deadlines that apply to legal challenges.

The implications for any future amendments to the political parties law will depend on the subsequent legislative process and any further legal steps permitted under Gabonese law.
