Court Affirms David Mark-Led ADC Leadership, Dismisses Abejide’s Suit

The Federal High Court in Abuja has affirmed the leadership of the African Democratic Congress (ADC) under former Senate President David Mark, dismissing a suit that sought to nullify the appointments of Mark and former Osun State Governor, Rauf Aregbesola, as the party’s National Chairman and National Secretary, respectively.

In a judgment delivered on Thursday, Justice Musa Liman held that the suit filed by Leke Abejide, the lawmaker representing Yagba Federal Constituency in the House of Representatives, lacked merit and was not justiciable because it bordered on the internal affairs of a political party. The court ruled that it had no jurisdiction to interfere in such matters except where there is a clear breach of the law or violation of a member’s legal rights.

Justice Liman upheld the preliminary objections raised by the ADC, its former National Chairman, Chief Ralph Nwosu, David Mark and Aregbesola, effectively dismissing Abejide’s claims.

The judge held that the plaintiff failed to establish that any of his legal rights had been infringed by the emergence of the current party leadership. He also ruled that Abejide did not exhaust the party’s internal dispute resolution mechanisms before instituting the suit, a requirement under the ADC Constitution and established legal principles governing disputes within political parties.

On the substantive issues, the court ruled that the transition of leadership from Ralph Nwosu to David Mark did not violate either the ADC Constitution or the Electoral Act, 2026.

Justice Liman explained that the July 2, 2025, gathering at the Shehu Musa Yar’Adua Centre in Abuja was merely a stakeholders’ meeting where Nwosu announced his intention to hand over the party’s leadership. According to the court, the formal emergence of David Mark and Aregbesola occurred during the National Executive Committee (NEC) meeting held on July 29, 2025, which was monitored by the Independent National Electoral Commission (INEC). The court held that the process complied with the party’s constitution and all applicable electoral laws.

Justice Liman consequently declared that David Mark’s emergence as National Chairman and Aregbesola’s appointment as National Secretary were valid and lawful.

The court also imposed financial penalties on the plaintiff and his counsel. Abejide was ordered to pay ₦2 million in costs to each of the defendants, while his lawyer was directed to pay ₦10 million in costs pursuant to the provisions of the Electoral Act, 2026.

Abejide had instituted the suit, marked FHC/ABJ/CS/1637/2025, seeking to invalidate the leadership transition within the ADC. He argued that Nwosu’s handover of the party’s leadership to Mark and Aregbesola was unlawful and asked the court to nullify the process.

He also sought perpetual injunctions restraining David Mark and Aregbesola from presenting themselves as the party’s National Chairman and National Secretary and asked the court to prevent INEC from recognising them, alleging that their emergence failed to comply with the Electoral Act.

However, Justice Liman rejected all the reliefs sought by the plaintiff and affirmed the legality of the leadership change, leaving the David Mark-led National Working Committee firmly in charge of the party.

The judgment is regarded as a significant legal victory for the ADC leadership as the opposition party continues preparations for the 2027 general elections. It also comes weeks after INEC reinstated David Mark and other members of the party’s National Working Committee on its official portal following a Supreme Court decision that set aside an earlier Court of Appeal order affecting the party’s leadership recognition. Despite Thursday’s ruling, other suits challenging the ADC leadership remain pending before the courts.
