The slow-moving trial of former Egyptian president Hosni Mubarak, alongside his two sons and former top aides, resumed on Sunday.
Mubarak is being retried for conspiracy to murder hundreds of demonstrators during the popular revolt in 2011 that ended his 30-year rule.
His two sons, Alaa and Gamal, are being retried alongside the ex-president for corruption and squandering public funds.
On Saturday, the presiding judge adjourned the case after bad weather grounded a helicopter bringing Hosni Mubarak to court, Al-Ahram reported.
A new round of hearings, due to last over a month, will hear evidence for the defence.
Mubarak and other co-defendants, including his former interior minister, Habib El-Adly, were present in court on Sunday.
The former president was released from prison last August after he served the maximum period of pre-trial detention. He is currently under house arrest at a military hospital in Cairo.
Mubarak was the first Arab ruler to be tried after the uprisings that swept the region. He was sentenced to life imprisonment for ordering the killing of demonstrators, but was granted a retrial in January 2013 on the grounds of procedural irregularities.
The 85-year-old also faces charges of squandering public funds by selling natural gas to Israel at below market prices.
Mubarak's first trial began in August 2011.
The trials of Mohamed Morsi and other Muslim Brotherhood leaders have shifted public attention away from the Mubarak retrials.
Morsi, Egypt's first freely elected president, faces multiple trials on an array of charges, including inciting the murder of opposition protesters and a jailbreak during the 2011 uprising.
The Islamist leader was ousted by the military in July 2013 following mass protests against his rule, which was marred by accusations of power-grabbing and worsening an already fragile economy.
