Egypt's Cairo Criminal Court decided Thursday to suspend the trial of ousted president Mohamed Morsi and 35 others charged with espionage to study requests to change the judges' panel, media reported.
The defence demanded that the court dissolve the judges' panel, arguing the panel was biased, Xinhua reported citing state-run MENA news agency.
Morsi's trial Monday over jailbreak charges was suspended for the same reason.
Morsi has been charged with breaking out of jail with the assistance of domestic and foreign forces during the Jan 25 uprising in 2011.
Morsi also appeared in court on charges of spying for foreign groups including the Palestinian Hamas movement to support terrorism in Egypt.
The other defendants included Muslim Brotherhood spiritual leader Mohamed Badie and his two deputies, Khairat al-Shater and Mahmoud Ezzat.
Morsi also faces charges for the killing of protestors during his one-year presidency. He is also expected to go on trial for "insulting the judiciary", but no date has yet been set for that case.
