Circuit Judge Thomas Jones had ordered Perry County District Attorney Michael Jackson to provide the information in the murder prosecution of former state trooper James Bonard Fowler.
The Alabama Supreme Court ruled Friday that the disclosure is prohibited by Alabama's judicial rules.
Fowler is charged in the 1965 shooting of Jimmie Lee Jackson during a protest in Marion.
His trial has been on hold pending a ruling on the witness list and other issues that still must be resolved.
