As for the ECHR interpretation of Convention art. 6 and 3., Enea vs. Italy and Mole vs. Italy sets the principles that defence rights can be partly sacrified on the bìground of compelling needs to protect the public interest to security, that is pretectig the ongoing of the investigation.
Decisions Salduz vs. Turkey and Simons vs. Belgium (the latter inadmissible) also stated that the right to counsel is not absolute from the moment of arrest, and may be delayed by ahtorities on grounds of public security.
As for the Italian law, the power to delay access to counsel is set in procedure code art. 104, §§ 3 and 4. This article was applied to all three suspects.
{Highlighting added to quote.}
The quoted cases, Enea v Italy 74912/01 and Mole v Italy 24421/03, concern the applications of mafia-connected persons who were subjected to special regimes in prison, in which they were denied a variety of communication benefits, such as limitations on family visits, access to telephones, and so on. They were also limited in some other usual benefits that prisoners generally receive. They were allowed to communicate with their lawyers by mail. The special regimes were ordered by decree of the Ministry of Justice for specific periods of time and were renewed, arguably at times without an effective way for the prisoner to appeal the renewal.
Both applicants complained that the special regime was a violation of Convention Article 3, the prohibition of torture and inhuman or degrading treatment. They also complained of a violation of Article 6.1, in that there was a limited appeal path to return to the regular prison regime. The ECHR found a violation of Article 6.1 for specifics in each case, but no over-all violation of 6.1, and no violations of Article 3.
These cases have no bearing on the application of Amanda Knox relating to the calunnia conviction, which (based on my opinion and that of other posters) would be primarily a claim of a violation of Convention Article 6.3c (absence of legal counsel during interrogation by police) with violation of Article 6.1 (unfair trial due to use of statement obtained by violation of Article 6.3c).
For those interested, here are short summaries of the Enea and Mole cases:
Enea v Italy 74912/01
Article 3
The Court noted that the restrictions imposed on the applicant under the special prison regime had been necessary in order to prevent him from maintaining contacts with the criminal organisation to which he belonged. It also noted that the courts responsible for the execution of sentences had lifted or eased certain of those restrictions and that Mr Enea had received treatment appropriate to his state of health, either in prison or in a hospital outside prison. Accordingly, it considered that the treatment to which the applicant had been subjected did not exceed the unavoidable level of suffering inherent in detention and concluded, by 15 votes to 2, that there had not been a violation of Article 3.
Article 6 § 1
With regard to the imposition of the special prison regime provided for in section 41 bis, the Court noted that prisoners subjected to that regime have ten days from the date on which the ministerial decree is served in which to lodge an appeal, which does not have suspensive effect, with the court responsible for the execution of sentences; the latter in its turn must give a ruling within ten days. The Court noted that for one of the 19 decrees issued against the applicant – decree no. 12 – the court responsible for the execution of sentences had given its ruling well after the 10-day deadline laid down in the legislation, and dismissed the appeal on the ground that the validity of the impugned decree had expired and that the applicant was consequently no longer subject to it. The Court considered that, since it had not resulted in a decision on the merits of the application of the special regime, the courts’ review of decree no. 12 had been deprived of its substance.
It concluded, unanimously, that there had been a violation of Article 6. {Only in this special case due to court delay.}
.....
On the merits, the Court noted that, while it was true that a prisoner could not challenge per se the merits of a decision to place him or her in an E.I.V. unit, an appeal lay to the courts responsible for the execution of sentences against any restriction of a “civil” right (affecting, for instance, a prisoner's family visits). In the present case, not only was the applicant not subjected to any such restriction but, if he had been, he would have had access to a court. Accordingly,
the Court concluded unanimously that there had not been a violation of Article 6 § 1 in this respect.
Mole v. Italy 24421/03
The applicant, Girolamo Mole, is an Italian national who was born in 1961 and lives in Parma (Italy). He is serving a life sentence for murder and other offences connected with the activities of a mafia-type criminal organisation. Relying in particular on Article 6 § 1 (right to a fair hearing), he complained that the exercise of his right of access to a court was restricted in that a complaint he lodged against a ministerial decree was not examined on the merits by the court responsible for the execution of sentences.
Violation of Article 6 § 1 (fairness)
