A Cook County, IL, judge on Friday ordered the surprise appointment of a special prosecutor to investigate the sudden dismissal of all charges against Jussie Smollett, saying the short-lived prosecution may have been legally invalid from the beginning.

Judge Michael Toomin ruled that State’s Attorney Kim Foxx had the right to withdraw herself from overseeing the prosecution of the onetime “Empire” actor but held no legal authority to then delegate that responsibility to her top deputy, the Chicago Tribune reports.

With the deputy holding no real authority, the Smollett case made its way through the court system without a prosecutor at the helm, the veteran judge said.

“There was no master on the bridge to guide the ship as it floundered through uncharted waters, and it ultimately lost its bearings,” Toomin wrote in the 21-page opinion. “... The unprecedented irregularities identified in this case warrants the appointment of independent counsel to restore the public’s confidence in the integrity of our criminal justice system.”

This is potentially bad news for Smollett, who could be re-charged over his alleged hate crime hoax by a special prosecutor. The whole episode has been costly for Smollett, who won’t return to his role for the final season of the Fox series. He also faces a lawsuit from the city of Chicago seeking to recoup the cost of police overtime for investigating the incident, and his attorneys have been sued for defamation by two brothers who claim Smollett paid them to help stage an attack on him.
