Justice Mohammed Umar fixed the date on Tuesday in Abuja after counsel for the plaintiff, Abdullahi Muhammad; Duke’s lawyer, Noah Abdul, and Azubuike Ogochukwu, who appeared for INEC, adopted their processes in the case.

The suit seeks the court's declaration that the 25 May primary election of the PRP from which Mr Duke emerged as the party's presidential candidate, was invalidated by overvoting in states like Bauchi, Gombe and Kwara.
