As many readers here may be aware, the provisional convictions of Knox and Sollecito on the murder/rape charges were due to flaws in those trials. What may not be fully understood is that many of those flaws are evidence of the survival into relatively current times (the year 2007 and later) of dysfunctional and unfair Italian judicial practices from the pre-1988 reforms of the Italian Code of Criminal Procedure and required, or still require, correction by further reforms of Italian laws or the Italian Constitution. One example from the Knox - Sollecito case was the effort to introduce the findings of Guede's fast-track trial into the Knox - Sollecito trials as was done in the Nencini Court of Appeal trial; such documentary evidence was claimed lawfully introduced under CPP Articles 238 and 238-bis. However, as pointed out in the Marasca CSC panel MR that quashed the Nencini judgment, that introduction was an unlawful ruse because (although possibly not explained fully in the MR) it violated CPP Articles 238, paragraph 5, and 192, paragraph 3, as well as Article 111 of the Italian Constitution, in the clause:
The guilt of the defendant cannot be established on the basis of statements by persons who, out of their own free choice, have always voluntarily avoided undergoing cross-examination by the defendant or the defence counsel.
This clause of the Italian Constitution was introduced only in 2001 (the current Italian Constitution dates from 1948). The clause was introduced as the result of the resolution of an ECHR case, Craxi v. Italy (No. 2). Here's a summary of this result from the DEJ/CoM website Factsheet on Italy:

Here's an excerpt from that CoM Resolution:
In conclusion, readers here should recognize the probability that the ECHR cases Knox v. Italy and Sollecito v. Italy do not merely affect the rights of Knox and Sollecito, but the laws as well as police and judicial practices of Italy that potentially affect the rights of all persons in Italy.
