The African Democratic Congress (ADC) is currently facing internal legal disputes regarding its leadership. Several state chapters, including those from Rivers and Lagos, have stepped forward in support of the National Working Committee (NWC), which is led by Senator David Mark. These chapters have denied any association with a recent suit filed at the Federal High Court in Abuja, which questions the leadership of Mark and claims that there were breaches in the party's constitution related to the formation of committees for the upcoming primaries in April 2026.

The legal action appears to have been initiated by ADC chairmen from multiple states, including Imo and Zamfara, who challenge the legitimacy of Mark's leadership and seek an injunction to prevent the conduct of primaries, suggesting serious dissent within the party. The plaintiffs have named the Independent National Electoral Commission (INEC) as a co-defendant in the suit, indicating the potential for broader implications on the electoral process if the matter escalates further.

This situation reflects ongoing tensions within the ADC, highlighting divisions that may impact its effectiveness and unity as it approaches significant electoral events. The party's response to these challenges, particularly through the support of key state chapters, may be crucial in stabilizing its leadership and maintaining its position in the political landscape of Nigeria as the date for the primaries approaches.
