Today's hearing in a court in the southern province of Minya comes amid a brutal crackdown on supporters of Morsi and the Muslim Brotherhood since the military overthrew him last July amid massive protests calling for his resignation.
The hearing has come under the spotlight after the judge, Said Yousef Sabry, sentenced an earlier batch of 529 defendants to death in just two sessions last month. That verdict is open to appeal, but has outraged the United Nations and human rights groups.
The rioting erupted as news spread that police had killed hundreds of Morsi's supporters while dispersing two Cairo protest camps.
The charges are similar to those faced by the 529 defendants.

Today's session will be the second for the around 700 defendants, after an opening hearing in March, which Sabry adjourned to announce the verdict.
Of the nearly 700 accused, about 50 are in custody while the rest are either out on bail or on the run.
The judgement can be appealed at the Court of Cassation, which would probably order a new trial or reduce the sentences, legal expert Gamal Eid said.
Under Egyptian law, the court pronounces a death sentence and refers the case to the top Islamic scholar, who plays an advisory role. It then ratifies the sentence in a subsequent hearing.
Defence lawyers boycotted the last session, branding it "farcical" after the mass death sentencing which the United Nations denounced as a breach of international human rights law.
