Supporters who have been fighting to have the courts hear exculpatory evidence have had their wish granted by the US Supreme Court today.
The Supreme Court has ordered a Georgia federal judge to determine whether there is evidence "that could not have been obtained at the time of trial (that) clearly establishes petitioner's innocence."
Since Davis' trial, seven of nine witnesses have recanted their testimony.
In the decision, Justice John Paul Stevens writes that "The substantial risk of putting an innocent man to death clearly provides an adequate justification for holding an evidentiary hearing."
Davis was convicted in 1991 of the shooting death of an off-duty Savannah police officer. New witnesses will be presented who say another man has confessed to the crime.
