A Cairo court confirmed on Saturday an earlier decision to acquit 17 people who were charged with ''illegally protesting" as they took part in a peaceful march near Tahrir Square on 24 January.
In May, a court decision acquitted the defendants, however, the prosecution appealed the acquittal decision.
Socialist activist Shaimaa El-Sabagh was among the participants in the peaceful march that aimed to memorialise those killed during the 25 January uprising. The 32-year-old mother was shot dead while heading to Tahrir Square with two dozen other peaceful marchers.
The 17 defendants came forward to testify in investigations of El-Sabagh's killing, but were later charged by the general prosecution.
Fourteen of the defendants belong to the Socialist Popular Alliance Party, as di El-Sabagh, while three do not.
The prosecution previously said investigations revealed El-Sabagh died from wounds sustained from "light birdshot" that a Central Security Forces (CSF) officer fired at her and other protesters. The police officer was charged with “beating that led to death,” then found guilty in a court trial and sentenced to 15 years in prison. His sentence was appealed.
