Rome, Italy (CNN) -- American student Amanda Knox, convicted last year of murdering her British roommate in Italy, faces a hearing Monday to determine whether libel charges should go ahead.
She and her parents are accused of defaming Italian police in the wake of her arrest for the killing of Meredith Kercher.
The case involves her allegations that police mistreated her in custody. Her parents face charges for repeating Knox's allegations.
Knox, 23, is also planning an appeal of her murder conviction. The appeal is due to begin November 24.
Knox was sentenced in December to 26 years in prison for the murder of the British exchange student in Perugia, Italy.
Kercher, 21, was found semi-naked with her throat slashed in the house she shared with Knox in November 2007.
Knox and her former Italian boyfriend, Raffaele Sollecito, 26, were found guilty in December 2009 of Kercher's murder.
Sollecito is serving a 25-year sentence.
A third person, Rudy Guede, a drifter originally from the Ivory Coast, was tried separately and is serving a 16-year prison sentence.
