The Supreme Court will on Tuesday hear separate appeals arising from leadership crises rocking two major opposition parties—the African Democratic Congress (ADC) and the Peoples Democratic Party (PDP).

At the centre of the ADC case is embattled National Chairman, Senator David Mark, who is challenging a Court of Appeal judgment affecting the party’s leadership structure.

Mark is seeking an order to stay execution of the March 12 ruling and restrain the Independent National Electoral Commission (INEC) from recognising any leadership other than his, pending the determination of the appeal.

“Unless this application is granted, the judgment of the Court of Appeal will be enforced and the appeal rendered nugatory,” his counsel, Realwan Okpanachi, argued.

The appeal, marked SC/CV/180/2026, is scheduled for hearing on April 14.

The dispute stems from a suit filed by a former Deputy National Chairman of the party, Nafiu Bala Gombe, who is challenging the legitimacy of Mark and Rauf Aregbesola as national chairman and secretary, respectively.

Following the appellate court judgment, INEC on April 1 removed their names from its official portal, escalating tensions within the party.

Meanwhile, Mark has also approached the Federal High Court seeking an order compelling INEC to restore the party’s leadership structure as it existed before the dispute, with Justice Emeka Nwite also fixing April 14 for hearing.

The ADC spokesperson, Bolaji Abdullahi, confirmed both matters are slated for the same day, raising the possibility that the lower court may defer to the apex court.

“Yes… they are scheduled on the same day,” he said.

In the PDP, the crisis has also reached the Supreme Court, with a faction backed by Oyo State Governor, Seyi Makinde, led by Tanimu Turaki (SAN), challenging an appellate court ruling that nullified its national convention and leadership.

The faction warned that allowing the judgment to stand could destabilise the party, hence its decision to seek a final resolution at the apex court.
