Ms. Bachelet expressed her extreme concern at the decision which, if carried out, would amount to “a gross and irreversible miscarriage of justice”.
The trial is one outcome of the military crackdown on Muslim-Brotherhood led protests in the Rabaa al-Adawiya and al-Nahda squares in Cairo on 14 August 2013.
It is alleged that up to 900 mostly unarmed protesters were killed by members of the Egyptian security forces.
The Government later claimed that many protesters had been armed, and that a number of police were killed.
Subsequently, charges were brought against a total of 739 people during a mass trial at the Cairo Criminal Court.
These charges included murder and incitement to violence, membership of an illegal group, participation in an illegal gathering, and other crimes.
In addition to the death sentences, 47 people were sentenced to life imprisonment, while the remainder were handed jail terms of varying length.
No security personel tried
There have been several mass trials in Egypt, involving hundreds of cases being heard at the same time, and raising many of the same issues about due process and fair trial standards.
“The conduct of the trial in the Cairo Criminal Court has been widely criticised,” Bachelet said.
“And rightly so. The 739 people were tried en masse, and were not permitted individual legal representation before the court. In addition, the accused were not given the right to present evidence in their defence, and the prosecution did not provide sufficient evidence to prove individual guilt. The evident disregard of basic rights of the accused places the guilt of all those convicted in serious doubt. I hope that the Egyptian Court of Appeal will review this verdict and ensure that international standards of justice are respected by setting it aside,”.
Ms. Bachelet also pointed to the stark contrast between Egypt’s mass trials and a recent law that effectively grants members of the security forces complete immunity for crimes they may have committed.
In July this year, the Egyptian Parliament approved a law that will effectively bestow immunity from prosecution on security force personnel for any offences committed in the course of duty between 3 July 2013 – the date the military overthrew the Government of President Morsi – and 10 January 2016.
“Justice must apply to all – no one should be immune,” the High Commissioner said.
“Attempts to bestow immunity from prosecution for crimes allegedly committed by members of the security forces merely promotes impunity, and undermines the faith of the Egyptian people in the Government’s capacity to deliver justice for all. I urge the Government of Egypt to ensure that justice will be done, according to law, in relation to any individuals – including members of the State security forces – who are suspected of committing a crime.”
To date, no State security personnel have been charged in relation to the so-called “Rabaa massacre”.
