Badie, along with 13 other Muslim Brotherhood leaders, is accused of inciting violence leading to deadly clashes outside Cairo University in July that left nine dead.
Speaking to reporters outside the Cairo court on Monday, Mohammed Al Damaty, Badie's defense lawyer, said the trials were "political, but masquerading as criminal cases."
"I also think that all the orders to keep them imprisoned are in effect detention orders under a legal cover."
The Muslim Brotherhood, Egypt's largest Islamist group, and the one from which Egypt's ousted president Mohammed Morsi hails, has organized a number of protests across Egypt since Morsi's deposal by the army on July 3.
More than 2,000 Islamists, including Morsi himself and top leaders of the Muslim Brotherhood, have been detained.
In an attempt to suppress these pro-Morsi rallies, the military-backed government issued a new law on Sunday banning protests without a police permit. AP
