Senegal's Constitutional Council Pulls the Brake on Sonko's Power Play

Senegal's Constitutional Council struck down a PASTEF-sponsored bill on 10 July 2025, ruling that legislation passed by the ruling party on 29 June to curtail presidential powers was unconstitutional in the form adopted. The unanimous decision is the first durable check on Prime Minister Ousmane Sonko since his party swept legislative elections in November 2024, and it reopens a fight inside the governing coalition that was assumed to be settled.

The ruling is technical in form and seismic in effect. The Council did not address the merits of reversing Senegal's semi-presidential architecture; it ruled that the procedural pathway PASTEF chose, a single omnibus bill, violated the Constitution's requirements for revising the fundamental law. That distinction matters. The substance remains live, and the Council has left the door explicitly open for a properly drafted revision. But the political effect is immediate: Sonko's project to ringfence executive power around his office, and away from President Bassirou Diomaye Faye, has been forced back to the drawing board under public humiliation.

The bill, and what the Council objected to

According to The Africa Report's 10 July coverage, the constitutional revision passed on 29 June by PASTEF lawmakers was meant to reduce President Faye's influence in favour of Sonko, who heads both the party and the National Assembly. The Council's complaint, as reported by The Africa Report in a second dispatch the same day, was procedural: a constitutional revision in Senegal requires the form and procedure set out in the Constitution itself, and the omnibus approach adopted by PASTEF did not meet that test.

That framing matters because it gives both sides a victory to claim. PASTEF retains the right to argue, after a redraft, that the substance of the reform is sound. The opposition, ranging from the Pastef predecessor parties to civil society coalitions that warned of a quiet constitutional coup, retains the right to argue that the process was reckless. The Council has acted as arbiter rather than vetoer, and the precedent set is one of institutional restraint rather than ideological adjudication.

The coalition fault line

The deeper story is what the bill reveals about the Faye-Sonko axis. When Faye won the presidential election in March 2024 with Sonko barred from running, the implicit deal was that Sonko would govern through the prime ministership while Faye held the ceremonial and foreign-policy heft of the presidency. The June bill was the first open attempt to convert that arrangement into constitutional text. The Council's ruling pushes the arrangement back into informal politics, which is precisely where the original deal lived, and where it can be renegotiated without a court sitting in judgment.

This is also why the opposition has been careful not to over-celebrate. The constitutional check is real, but the political asymmetry is not. PASTEF holds the National Assembly. Sonko controls the party machinery. Faye, whatever his personal ambitions, governs from a palace whose powers the Council has just declined to formally rewrite. A ruling against the bill is not a ruling against the government, and it would be a mistake to read it as the beginning of the end for either man.

What the ruling does not change

It is worth being precise about what the Council did and did not decide. The Council did not endorse President Faye's powers. It did not pronounce on whether Senegal ought to be a semi-presidential or parliamentary system. It did not touch the November 2024 electoral result, which delivered PASTEF a working majority, or the March 2024 presidential result, which delivered Faye the palace. The ruling rests on a procedural defect, and a future government can return with a properly drafted bill and force a fresh reckoning.

That procedural thinness cuts both ways. PASTEF can argue, accurately, that the constitutional architecture is unsettled and that the will of the elected majority should prevail. The opposition can argue, also accurately, that constitutional revisions require more than a single-chamber vote and that the Council has now set the standard against which any future attempt will be measured. The dispute has been paused, not resolved.

Stakes and the calendar ahead

The political calendar in Dakar will now run on two tracks. The first is procedural: PASTEF's legal team will need to decide whether to redraft, split, or withdraw. The second is political: the opposition will need to decide whether the ruling gives it enough oxygen to contest the next electoral cycle, or whether it is a single win in a longer losing streak. Senegalese civil society groups that filed amicus-style objections to the bill will want to see their arguments entrenched in any new draft.

For investors and regional partners, the message is one of institutional capacity rather than instability. A Constitutional Council that rules against the government is a sign that the system built after the 2024 transition still has friction in its joints. That is good news for the rule of law, and only mildly bad news for the predictability of executive action. The West African regional frame, dominated by coups in Mali, Burkina Faso, Niger, and Guinea, makes Senegal's continued constitutional politics a more valuable signal than the underlying dispute deserves.

The most plausible scenario through the end of 2026 is that the bill is redrafted in a form the Council can accept, and that the underlying power shift proceeds in slower motion. The least plausible is that PASTEF walks away from the project entirely. The Council has bought time, and the clock is now Sonko's to manage.

Desk note: The wire coverage of the 10 July ruling is sparse outside francophone and pan-African outlets; this piece leans on The Africa Report's same-day dispatches and treats the Council's published reasoning as the authoritative record. Where international wires pick up the story in coming days, expect framing that emphasises institutional resilience over the intra-coalition tension that actually drives the dispute.
