Dr Johnson Chukwuka, an Action Democratic Party (ADP) presidential aspirant, files a legal challenge against the ADP and the Independent National Electoral Commission (INEC) in Nigeria’s Federal High Court in Abuja. The case contests the emergence of Abbas-Bin Aliyu as the ADP’s presidential candidate for the 2027 election and seeks court orders to overturn the nomination.

Across reports, Chukwuka argues the party does not conduct a valid presidential primary on 29–30 May 2026. He asks the court to declare the primaries invalid, nullify the “purported” declaration of Aliyu as winner, and prevent or unwind the submission of Aliyu’s name to INEC after it is published on INEC’s notice board on 1 August. He also seeks recognition as the duly elected ADP candidate.

One outlet adds details of internal ADP dispute actions: the party petitions the Inspector-General of Police over an alleged unauthorised upload of a presidential nomination form to INEC’s portal. The party reportedly points to a former staff member, and it asks INEC to preserve electronic audit trails, including login records and related data, to support its concerns. Overall, the outlets agree the matter is before the courts ahead of the 2027 polls, with INEC and the party named as respondents.
