Justice Omotosho held that the allegation on which the House of Assembly based the impeachment proceedings was untenable in law and constituted gross misconduct.
He ordered the Inspector-General of Police to provide him with needed security to enable him to resume office and perform the functions of the office until the end of his tenure.
The court warned that any individual, aside from Shaibu, parading themselves as deputy governor would face legal consequences.
The court also set aside the appointment of Omobayo Godwin as the new deputy governor, replacing Shaibu.
