His current attorney, Stacey Jackson, is defending his position as Registe's counsel.
The state says Jackson should not represent Registe because he worked for the Muscogee County District Attorney's Office during Registe's indictment, reportedly requesting phone records pertaining to the double murder case.
Tuesday, Jackson and the state made their arguments to the state supreme court.
"The crux of the case was that any substantial involvement in the case would trigger a conflict and it's been our position since day one that signing a request for phone records is not substantial involvement in the murder case," Jackson told WTVM after the proceedings.
Jackson hopes the judge's order preventing him from representing Registe will be overturned by the supreme court.
He expects the supreme court to make a ruling within the next 60 to 90 days.
