The Department of State Services (DSS) has formally closed its case against Nasir El-Rufai, the former governor of Kaduna State, in the ongoing trial concerning alleged illegal wiretapping.
The development marks a significant procedural shift in the high-profile legal battle before the Federal High Court in Abuja.
With the security agency's investigation concluded, El-Rufai's legal team is now positioned to file a no-case submission.
This move argues that the prosecution has failed to establish a prima facie case, potentially leading to the dismissal of charges before the defense is required to present its own evidence.
The filing represents a critical juncture in the proceedings, which have previously featured testimony from human rights lawyer Deji Adeyanju and the replaying of key interview materials.
The case has drawn considerable attention within Nigeria's political and legal circles, given El-Rufai's prominent status as a former governor and current political figure.
