Prosecutors are arguing that the acquittal of Knox and her former boyfriend Raffaele Sollecito on appeal in October 2011 was flawed.
The pair spent four years in jail for the murder of the 21-year-old student in Perugia in November 2007. They have both always denied any involvement in the murder. The killing and subsequent trials made headlines around the world.
Knox and Sollecito had been facing 26-year and 25-year jail terms respectively following their initial convictions in 2009. But they were acquitted after the defence successfully argued that DNA evidence on a kitchen knife, thought to be the murder weapon, could be flawed.
Knox, who now lives in her home town of Seattle, was ‘very anxious’ about the latest hearing, according to her Italian lawyer.
If the court upholds the October 2011 verdict, this protracted case will finally be over and Knox and Sollecito will have their innocence confirmed in the eyes of the law.
However, if the court rules against the verdict, a new appeals process would be reordered, meaning there would be a retrial, he adds.
The case began in 2007, when Knox moved to Perugia, Italy, to study at the University for Foreigners of Perugia for one year. Knox, then 20, shared a room with British student Meredith Kercher (21). That November, Kercher’s semi-naked body was found at their home, with her throat slashed.
