The Federal High Court in Abuja has nullified the leadership of the African Democratic Congress (ADC) led by former Senate President, David Mark, invalidating all decisions taken by the party under the leadership, including the emergence of former Vice-President Atiku Abubakar as its presidential candidate for the 2027 general elections.

Delivering judgment on Thursday, Justice Peter Lifu declared the Mark-led Caretaker Committee illegal, ruling that its emergence violated the ADC constitution, relevant provisions of the Electoral Act and the 1999 Constitution.

The court also nullified the emergence of former Minister of Interior, Rauf Aregbesola, as the party’s National Secretary, alongside other national officers and all nominations made by the party for the 2027 elections.

The judgment followed a suit marked FHC/ABJ/CS/1819/2025, instituted by former ADC Deputy National Chairman, North-East, Nafiu Bala Gombe, who challenged the process through which Mark and other members of the caretaker committee assumed control of the party.

Gombe argued that following the resignation of the former National Chairman, Ralph Nwosu, he was constitutionally entitled to assume leadership of the party.

He consequently asked the court to invalidate the actions of the Mark-led leadership and restrain Mark and Aregbesola from parading themselves as National Chairman and National Secretary respectively.

Upholding the plaintiff’s case, Justice Lifu also directed that INEC should not recognise or act on decisions taken at the party’s 99th National Executive Committee meeting held on July 27, 2025.

Speaking after the judgment, counsel to Gombe, Lukman Fagbemi (SAN), said all actions taken by the ADC since July 27, 2025, had been annulled.

Another counsel to the plaintiff, Luka Musa Haruna (SAN), said the judgment effectively left the party without candidates for any elective position in the 2027 elections, including the presidency, governorship, Senate and House of Assembly.

However, the party’s National Welfare Secretary, Nkemakolam Ukandu, who was joined in the suit as an interested party, said the ADC would appeal the judgment.

The ruling came barely 24 hours after Atiku Abubakar, whose name had earlier been published by INEC as a presidential candidate, held a campaign rally in Sokoto State.
