The court’s Judge, Ahmed Refaat also announced that Mubarak and Al-Adly, who will face the death penalty if found guilty, are going to be tried at the same time.
The judge also barred television cameras from entering the court, and said the trial will be held behind closed doors.
In the first court session on 3 August, Mubarak pleaded not guilty and denied the charges of ordering the killing of protesters during the 18-day uprising that lead to his downfall.
Al-Adly has already been sentenced to 12 years in prison for corruption.
At least 850 protesters died during the protests in Egypt.
Mubarak is the first Arab leader to stand trial in person since uprisings swept the Arab world.
