The Senate has passed a bill seeking to amend the 1999 Constitution to provide for the establishment of state police services across the federation.
The lawmakers passed the bill on Wednesday.
Earlier, the senators resolved to adopt manual voting for the consideration of the state police bill after its electronic voting device developed a technical fault.
The resolution came after concerns among senators that some lawmakers could be disenfranchised if the chamber proceeded with the faulty device.
In the manual voting, each lawmaker will stand, announce their names and openly declare their positions on the proposed state police framework.
