The trial of former Egyptian president Hosni Mubarak, his sons Gamal and Alaa, former interior minister Habib El-Adly and his six aides resumed on Monday.

Mubarak arrived at the court by military helicopter from Tora Prison Hospital.

Presiding Judge Mahmoud El-Rashidi began the third hearing of the trial, which began in May, by asking the defendants to confirm their names. "Thank God it's correct this time, sir," Alaa Mubarak said, in reference to several slips by the judge in previous sessions.

The judge then went through a number of exhibits, including a CD, an envelope and a flash drive.

Defence lawyers asked for access to all documentary evidence in the case and for adequate time to read it. The judge then announced a 45-minute recess.

A small number of relatives of those killed during the 2011 revolution were outside the court amid a heightened security presence.

In its last session on Saturday, the court rejected all civil complaints filed by the plaintiffs' lawyers and said they should be referred to a court with the appropriate jurisdiction.

The decision was "shocking" and could signal the court is preparing to acquit Hosni Mubarak, Muslim Brotherhood lawyer Abdel-Moneim Abdel-Maqsoud told Aswat Masryia news website.

Mubarak, who received a life sentence in June 2012 for "failing to protect" unarmed anti-regime protesters during Egypt's 18-day uprising in early 2011, was granted a retrial in January due to procedural irregularities in the initial trial.

Mubarak, together with El-Adly, is accused of complicity in the killing demonstrators during the uprising. The ex-autocrat, together with his two sons, also faces corruption charges. The trial is being held at the Police Academy in Cairo, formerly known as Mubarak's Security Academy, where his police cadets used to receive their four-year training before joining the force.

Hosni Mubarak, business tycoon Hussein Salem and former minister of petroleum Sameh Fahmy are also accused of exporting gas to Israel at below-market prices, causing Egypt to lose LE714 million throughout the deal. Salem, who is now in Spain, also faces charges of using his connections with the Mubarak family to illicitly expand his profit.
