Well then it must be acknowledged that Curatolo had a wonderful sense of timing and irony, as the last court to hear him, was so offended as to cut short his appearance.
{1} Does this mean that under ECHR principles, the last court to judge him in person is considered a definitive finding that he is an unreliable witness?
Mignini's go to witness, testified in two other murder trials, at least one of which resulted in a conviction according to Frank's blog.
Wonder if Curatolo's other victims may benefit from the fall out of this case?

Thinking about your question (1). ECHR states it doesn't evaluate the reliability of individual items of evidence; that is the responsibility of the domestic tribunals. ECHR states that its mandate is to evaluate whether a trial overall was fair or unfair (and other claims of violations of the Convention). So it would examine the Curatolo issue in relation to all the other evidence. In doing this, ECHR would look at the practical evaluation of each significant item of evidence, the adversarial contest over the evidence, and whether the judges' evaluations were reasonable rather than arbitrary or conclusory.
