The Alliance of Sahel States opened the first joint session of its confederal parliament in Niamey on 24 August, running through 29 August. The session brings together the transitional legislative bodies of Mali, Burkina Faso and Niger, each of which has governed under military-led rule since 2020-2023: Mali’s National Transition Council, Burkina Faso’s Legislative Assembly of the People, and Niger’s Consultative Council for Refoundation. According to Niger’s state news agency ANP, the presidents of the Malian and Burkinabé bodies arrived in Niamey over the two days preceding the opening, received by their Nigerien counterpart, Dr Mamoudou Harouna Djingarey.
This session is the product of a slow institutional build, not a sudden move. The AES Confederation was created by treaty in July 2024, itself following the three states’ January 2024 withdrawal from ECOWAS. ActuNiger reported that it took until 29 June 2026 for the presidents of the three legislative bodies to meet in Ouagadougou and commit specifically to operationalizing this confederal parliamentary session. ANP separately reported that AES senior officials only conducted a mid-term review of the bloc’s “Year II roadmap” in Niamey on 17 August. Read against that timeline, this week’s opening is less a milestone than a scheduled deliverable, one that took roughly two years from treaty to first joint sitting.
What makes this worth tracking is the gap it is meant to fill. By leaving ECOWAS, the three states also left its shared legal and regulatory architecture, common external tariff, free movement protocols, harmonized trade rules. A confederal parliament tasked with harmonizing legislation across the AES states is, in effect, building a replacement framework from scratch. AES officials have framed this explicitly in sovereignty terms; ANP’s coverage of a 19 August conference in Niamey, organized under Burkina Faso’s AES national commission, noted the event was titled around “the battle for the conquest of sovereignty” within the confederation. That framing signals intent, but intent is not the same as legislative output, and a five-day inaugural session is a thin window to produce binding harmonized text on anything as complex as trade or investment codes.
What to watch: whether the session produces actual harmonized legal instruments, such as a shared trade or investment code, rather than another joint declaration restating the bloc’s founding principles; how this new confederal body’s mandate is meant to interact with each country’s existing national legislative structure, since none of the three has been superseded; and whether any concrete timeline emerges for when businesses operating across AES borders can expect a single legal framework to replace the ECOWAS rules their governments opted out of.
