Former Egyptian President Hosni Mubarak, currently serving a life term in prison, will receive a retrial. Al Jazeera  reports that this opportunity may give the dictator, who was found guilty last year in the deaths of protestors in 2011, a chance at a verdict of not guilty.
No date has been set for the start of their retrial.
Mubarak and Habib el-Adly, the former interior minister, were sentenced to life in prison in June last year in a court ruling that held them responsible for the deaths of protesters killed by security forces trying to put down the uprising.
Crowds of Mubarak supporters attending the trial cheered.
The 84-year-old former leader was moved from prison to a military hospital in late December after breaking ribs in a fall.
Mina Khalil, a law professor at the University of Cairo, told Al Jazeera "any sentence they get can't be harsher than what they got and it is possible they can get a verdict of innocence.
