This comes even after the Court of Appeal had granted an order directing the commission to allow them access.
A member of the team, Silas Onu, told Channels television that INEC has continued to deny them access to the materials, which had been inspected and paid for in the previous week.
Onu revealed that efforts to meet with INEC’s legal team have become an uphill task.
He, however, made it clear that they will continue to follow up until the commission complies with the court order.
Onu also warned that they may be forced to file for contempt against the INEC chairman and other officers of the commission if they do not give a positive response soon.
Meanwhile, INEC’s director of Voter Education and Publicity, Oluwole Osaze-Uzzi, says the claims are not true but if the PDP is insisting on that position they should go back to the court and file a complaint.
