Supreme Court to decide leadership of Nigeria's African Democratic Congress amid Atiku's presidential bid

The African Democratic Congress (ADC) is poised for a decisive legal battle that could reshape Nigeria's opposition landscape ahead of the 2027 presidential election. Justice Peter Lifu of the Federal High Court ruled on 6 November 2026 that former Senate President David Mark’s leadership was invalid, thereby voiding all actions from his period in charge, such as the party’s selection of former Vice‑President Atiku Abubakar for the presidential race. The ruling has sent the party into fresh uncertainty, with the Mark faction announcing plans to appeal while former Deputy National Chairman, North, Nafiu Bala Gombe hailed the judgment as a victory for constitutional governance.

The dispute centres on a leadership transition that took place earlier in the year when former ADC National Chairman Ralph Nwosu facilitated the appointment of David Mark as National Chairman and former Osun State Governor Rauf Aregbesola as National Secretary. The arrangement was intended to provide a united platform for opposition figures challenging President Bola Tinubu in the 2027 election. However, Gombe contested the transition, arguing that the party’s constitution prescribed a different succession procedure that was not observed.

Background

The legal contest over ADC’s leadership has unfolded across multiple courts. In July 2026, Justice Musa Liman of the Federal High Court heard a separate suit filed by House of Representatives member Leke Abejide and upheld preliminary objections, including lack of jurisdiction and failure to exhaust internal party remedies. Liman’s judgment favoured the defendants, effectively supporting the Mark‑led leadership. The Mark camp subsequently argued that a court of coordinate jurisdiction could not overturn Liman’s decision, a point that remains unsettled.

Previously, on 30 April 2026, the Supreme Court stepped in to overturn a prior status‑quo‑ante‑bellum directive and ordered a swift trial at the Federal High Court, yet it refrained from determining the rightful head of the ADC. The recent judgment by Justice Lifu therefore represents the latest judicial pronouncement in a series of conflicting rulings, with the ultimate resolution now expected to rest with the Supreme Court.

Why it matters

The outcome of the case carries significant implications for several key political actors. Atiku Abubakar’s presidential campaign, launched in Sokoto just 24 hours before the Lifu judgment, now faces the prospect of losing its party platform if the Mark‑led leadership is deemed illegitimate. The ADC was envisioned as a coalition hub for opposition forces; its destabilisation could fragment the anti‑APC front and alter the dynamics of the 2027 election.

For David Mark and his allies, an adverse Supreme Court ruling would constitute a major setback at a critical juncture, potentially diminishing their influence within the party and the broader opposition. Conversely, Gombe’s victory in the Federal High Court reinforces his claim that the party’s constitution must be adhered to, a stance that resonates with party members concerned about procedural integrity.

The legal tussle also underscores the role of Nigeria’s judiciary in adjudicating internal party disputes, highlighting the interplay between party constitutions, the Electoral Act and the courts’ jurisdictional boundaries.

What happens next

Both factions have indicated their next steps. The Mark camp has signalled its intention to appeal the Lifu judgment to higher courts, emphasizing that the earlier Liman decision should prevail. Gombe, meanwhile, has welcomed the ruling and is likely to seek a final determination from the Supreme Court, which has already shown willingness to intervene in ADC matters. The Supreme Court’s forthcoming decision will determine whether the party’s leadership—and consequently Atiku’s candidacy—remains intact or requires restructuring before the 2027 electoral contest.

The case remains active, with the appellate process expected to unfold over the coming weeks, and the political stakes for Nigeria’s opposition coalition continuing to rise.
