elapid argument is more or less correct.
Blood bags from OP were requested by Italy's Justice under an agreement of collaboration between Justice administrations of different European countries. This agreement allows the exchange of evidences (and also the extradition of alleged criminals) subject to two conditions:
* The criminal offence in the demanding country is also recognised as such in the country of origin
* Any verdict or judgment made based on the evidences can be appealed to a Court of Justice
None of these apply in Valverde's case:
- Doping was not a criminal offence in Spain in 2006. Doctors could be prosecuted then for bad medical practices, as well as team managers, but athletes could not.
- CONI's verdict cannot be appealed to a Court of Justice
Judge Serrano knew this and rejected all demands from Italy's justice. But Italy's justice made the trick to send the request when Judge Serrano was on leave and his deputy wasn't aware of the game.
