Justice Obiora Egwuatu of the Federal High Court in Abuja has stepped down from a case involving suspended Senator Natasha Akpoti-Uduaghan.
Justice Egwuatu was assigned to hear the suit, but on Tuesday, he announced that he would no longer handle the matter.
He made this decision after Senate President Godswill Akpabio wrote a petition questioning his impartiality.
Although the case was scheduled for hearing, when the court clerk called it up, the judge ruled that he was stepping aside.
He said he would return the case file to the Chief Judge, who would assign it to another judge.
On March 4, Justice Egwuatu issued an interim order stopping the Senate Committee on Ethics, Privileges, and Public Petitions from proceeding with disciplinary actions against Akpoti-Uduaghan.
She was accused of violating Senate rules.
