Mohamed Morsi and 14 other figures from the Muslim Brotherhood are charged with inciting the killing of protesters near the presidential palace in 2012.
At a hearing in another trial four days ago, a defiant Mohamed Morsi shouted that he was still the legitimate president.
The ousted was deposed by the army last year after huge crowds rallied against him.
Mohamed Morsi is now facing four separate criminal trials on various charges.
His Islamist supporters say the charges against him are politically motivated, although officials insist the trials are free and fair.
Mohamed Morsi was flown in by helicopter on Saturday morning from his prison in Alexandria.
Heavy security has been deployed outside the National Police Academy compound where the hearing is taking place.
On Friday, riot police fired tear gas at hundreds of Mohamed Morsi supporters in Cairo and Alexandria and Fayoum, south of the capital.
Islamists have staged regular protests demanding the reinstatement of Mohamed Morsi but have been met with a heavy crackdown in which hundreds have died.
The Muslim Brotherhood has been declared a terrorist organization and authorities have punished any public showing of support for it.
Human rights groups have dismissed some of the allegations against Mohamed Morsi as preposterous.
There were chaotic scenes when he first appeared in court in early November for the trial resuming on Saturday.
Mohamed Morsi chanted slogans against the current government and the court. He also refused to recognize the court’s legitimacy or put on the required prison uniform.
