11. Examining this sequence of events, the ECHR will have no problem with Knox's choice of remedy and clearly the remedy was exhausted.
Here's a specific case to illustrate the ECHR's case-law.
Amanda Knox complained of police mistreatment in court and in each of her appeals against the judgment of conviction for calunnia, and on Nov. 6, 2007, soon after her interrogation reported the police mistreatment in writing (Memoriale 1) delivered to the police, but did not file a formal complaint to the authorities.
Some posters have argued that this means that she did not exhaust domestic remedies regarding her claim before the ECHR of a violation of Convention Article 3, the prohibition of torture or inhuman or degrading treatment.
However, this situation of an individual complaining of police mistreatment in court but not filing a formal complaint has come up previously.
The ECHR has found that the complaint in court is sufficient, because the States ("The High Contracting Parties" including Italy) that have signed the Convention treaty have pledged on the basis of Article 1: "The High Contracting Parties shall secure to everyone within their jurisdiction the rights and freedoms defined in Section I of this Convention." These rights include, of course, Article 3.
Here's an example from ECHR case-law:
Grinenko v Ukraine 33627/06 15-11-2012
Grinenko maintained that Ukraine had violated his rights under Convention Articles 3 (prohibition of torture or inhuman or degrading treatment), 5 (right to liberty, prohibition against arbitrary detention), and 6 (right to a fair trial) in the course of a criminal case: an allegation that he had ordered a murder for hire.
Before the ECHR, Ukraine's defense was that Grinenko's application for violation of Article 3 was inadmissible because he had not followed proper procedures for a complaint in the Ukrainian justice system. He had repeatedly mentioned his complaint in court proceedings, but had not filed the appropriate formal complaint with the authorities.
ECHR judgment: State authorities must take action whenever there is any credible allegation of mistreatment by State agents, and statements by an alleged victim in court are adequate to bring such allegations to the level of requiring an effective investigation. Failure of Ukraine to conduct an effective investigation was thus a violation of Convention Article 3.
The relevant excerpt from the ECHR judgment:
61. The Court reiterates that where an individual makes an arguable claim that he has been ill-treated by the State authorities in breach of Article 3, that provision, read in conjunction with the State’s general duty under Article 1 of the Convention, requires by implication that there should be an effective official investigation. ....
62. ... [T]he Court considers that the applicant made an arguable complaint of ill-treatment before the domestic authorities which triggered their procedural obligation under Article 3 of the Convention to carry out an effective investigation of the alleged facts. Meanwhile, the applicant’s allegations were examined exclusively by the courts in the course of legal argument concerning the admissibility of evidence at trial. ....

With all the evidence in the above posts, including the specific case-law of Grinenko v. Ukraine, a reasonable and objective person would conclude that Knox had met the ECHR criteria for exhausting domestic remedies.
