Speaking to ITV News from the family home in Coulsdon in south London, Meredith Kercher's sister Stephanie said:
We welcome the news in the sense that we hope to find the answers. We are never going to be happy about any outcome because we have still lost Meredith but we obviously support the decision and hope to get answers from it.
There are still so many unanswered questions, all we have ever wanted to do is do what we can for Meredith and to find out the truth of what happened that night.
Rudy Guede's conviction was on the basis that there was more than one person there so that is something that needs to be looked into.
- The US and Italy brought an extradition treaty into force in 1984
- It obliges each country to extradite anyone charged with or convicted of an extraditable offence by a jail sentence of more than one year
- In this case, Italy must give the US specific documents to show they have "probable cause to believe" that Meredith Kercher was murdered, and Miss Knox committed the offence
What do we expect? A decision based on justice, so we expect a good outcome.
It was painful to receive the news that the Italian Supreme Court decided to send my case back for revision when the prosecution's theory of my involvement in Meredith's murder has been repeatedly revealed to be completely unfounded and unfair.
I believe that any questions as to my innocence must be examined by an objective investigation and a capable prosecution.
The prosecution responsible for the many discrepancies in their work must be made to answer for them, for Raffaele's sake, my sake, and most especially for the sake of Meredith's family.
Our hearts go out to them. No matter what happens, my family and I will face this continuing legal battle as we always have, confident in the truth and with our heads held high in the face of wrongful accusations and unreasonable adversity.
In a statement, Amanda Knox added that the prosecutors' theory of her involvement in the murder is "completely unfounded and unfair".
No matter what happens, my family and I will face this continuing legal battle as we always have, confident in the truth and with our heads held high in the face of wrongful accusations and unreasonable adversity.
If she is convicted at that trial and if the conviction is upheld by the highest court, then Italy could seek her extradition.
- Italian law cannot compel Amanda Knox to return from the US for the new trial
- The court could declare her in contempt, but that carries no additional penalties
- It is unclear what will happen if she is convicted in a new appeals trial, but Italy can seek her extradition
- It would then be up to the United States to decide if it honors the request
- US and Italian authorities could also come to a deal that would keep Knox in the United States
Reacting to the retrial, Amanda Knox says it is "painful" to have acquittal overturned, but "confident" in the truth.
- Last year, prosecutors filed a motion to appeal against the acquittals, calling the verdicts "contradictory and illogical"
- Italy's top appeal court examined whether there were irregularities which gave grounds for a retrial, rather than assessing the details of the case
- Knox returned to her Seattle-area home after she was released from prison in Italy and had been scheduled to speak publicly about the trial for the first time on American television in April
- The new trial will be held before a court in Florence
Speaking to Sky News, the sister of Meredith Kercher, Stephanie, welcomed today's decision. She said there were "questions still unanswered", and it was "a step towards finding out the truth".
