Morsi was flown by helicopter to the police academy compound where the trial was being held, then transferred to the courtroom in a minibus. The trial was not televised live, but state TV later released video of him buttoning up his dark blue jacket, flanked by policemen, as he stepped out of the minibus.
He refused to wear a prison uniform and donned instead a suit, but no tie. By contrast, his 14 co-defendants, prominent members of his Muslim Brotherhood, wore the white prison garb as they stood in two lines like a guard of honor and applauded Morsi as he joined them in the defendants' cage.
The footage had no audio so Morsi could be seen but not heard talking. Reporters allowed in the courtroom were not allowed to bring cameras, computers or cellphones as authorities sought to maintain tight control over the proceedings, clearly amid fear of stoking protests and clashes outside.
Independent photographers and video journalists were not allowed in
Morsi, Egypt's first freely elected president, had been held at an undisclosed location since the July 3 coup but was moved to a prison near Egypt's second-largest city of Alexandria after the trial ended.
Morsi and co-defendants face charges of inciting the killing of protesters who massed outside the presidential palace in December, demanding he call off a referendum on a new constitution drafted by his Islamist allies. Brotherhood members attacked a sit-in by the protesters, sparking clashes that left 10 people dead. If convicted, Morsi and the 14 other defendants could face the death penalty.
The longtime Brotherhood leader rejected the proceedings and said he had been forced to attend.
"This is a military coup whose leaders must be put on trial in accordance with the constitution," Morsi told the court.
"I am the president of the republic and I am here against my will," he said. "What is happening here is providing cover for the military coup," he said, as his co-defendants chanted "down, down with military coup."
Monday's raucous session reflected the highly charged atmosphere of a nation deeply polarized between Morsi's Islamist supporters, and the military-backed administration and moderate Egyptians who support it.
Supporters from both sides rallied outside the police academy, although the protests were significantly smaller than past gatherings as much of the Brotherhood's leadership has been arrested in a crackdown.
Morsi's supporters rallied outside the police academy, carrying posters with his photo and banners depicting an open palm with four fingers the symbol commemorating a pro-Morsi sit-in that was violently cleared by security forces in August. They also chanted slogans against Gen. Abdel-Fattah el-Sissi, the military chief who led the July coup.
Police fired in the air and used tear gas to end clashes between the two sides outside a major court complex in Cairo's downtown area. Police also used tear gas to disperse thousands of Morsi supporters in the southern city of Assiut.
The start of the hearing was delayed by nearly two hours over what the officials said was a dispute over Morsi's refusal to wear a prison uniform, part of his rejection of the trial's legitimacy. The officials spoke on condition of anonymity.
The judge, Ahmed Sabry Youssef, had to adjourn the hearing twice because the chants disrupted the proceedings. The proceedings were adjourned until Jan. 8 to allow defense lawyers to review documents, the court's secretary said. Defense lawyers said the judge has ruled that they have access to their clients in prison.
It was not immediately clear where Morsi was taken after the adjournment. State TV initially reported he was to be transferred to the main prison in Cairo where his co-defendants are being held. But later it reported he was being taken to a prison in the desert near Alexandria.
The military says it removed Morsi only after the public turned against him with protests by millions demanding his removal, accusing him and the Brotherhood of trying to subvert the law and impose their will on the country. Morsi's supporters accuse the military of crushing Egypt's nascent democracy by overturning the results of multiple elections won by the Islamists since the ouster in 2011 of autocrat Hosni Mubarak in a popular uprising.
Rights advocates have expressed concern about the fairness of the trial as it is taking place in the atmosphere of a widescale crackdown on the Brotherhood and its Islamist allies in which several thousand have been arrested and hundreds killed. The judicial system also is stacked with Morsi's adversaries, with whom he clashed repeatedly during his yearlong presidency.
In a last-minute change, authorities on Sunday switched the trial's venue in a move apparently aimed at thwarting mass rallies planned by Morsi's Brotherhood.
Security was tight around the police academy, with hundreds of black-clad riot police backed by armored vehicles deployed around the sprawling complex. Police helicopters hovered over the site. The final stretch of road leading to the academy was sealed off, with only authorized personnel and accredited journalists allowed to approach the facility.
The academy also being used for the re-trial of Mubarak, charged with failing to stop the killing of some 900 protesters during the 18-day uprising that toppled his 29-year regime. But unlike Mubarak's first trial, the proceedings against Morsi were not aired live.
