ROME — Italy's high court on Tuesday harshly faulted the appeals court that acquitted American student Amanda Knox of murdering her roommate, saying its ruling was full of "deficiencies, contradictions and illogical" conclusions.
It ordered a new appeals court to consider all the evidence to determine whether Knox helped kill the young woman.
In March, the high court overturned Knox's acquittal in the 2007 murder of British roommate Meredith Kercher, 21, and ordered a new trial. On Tuesday, the court issued its written reasoning for doing so.
The 74-page document picked apart the 2011 appeals court decision that freed Knox, faulting the judges for ignoring some evidence, considering other evidence insufficiently and undervaluing the fact that Knox had initially accused a man of committing the crime who had nothing to do with it.
The high court said the appeals decision "openly collides with objective facts of the case."
Kercher's body was found in November 2007 in her bedroom of the house she shared with Knox in Perugia, a central Italian town popular with foreign exchange students. Her throat had been slashed.
Knox, now 25, and her Italian ex-boyfriend, Raffaele Sollecito, 29, were initially convicted of the crime and sentenced to long prison terms.
The appeals court acquitted them in 2011, criticizing virtually the entire case mounted by prosecutors.
Knox and Sollecito denied any involvement. A young man from Ivory Coast, Rudy Guede, is serving a 16-year sentence.
Knox left Italy a free woman after her 2011 acquittal.
Italian law cannot compel Knox to return for the new trial.
