I'm no lawyer, and even less an Italian lawyer, but it seems to me that the ISC in 2013 missed an important modifier to that bit, "each piece of evidence."
It should have said something akin to, "each piece of evidence with merit."
Indeed.
The Chieffi panel of the CSC violated Italian procedural law in their judgment. So did the Massei and Nencini courts, so there was some consistency to these violations.
The specific provisions violated by "each piece of evidence doesn't need to be certain but rather all of the evidence needs to be taken as a whole" include CPP Art. 192 Evaluation of evidence, para. 2: The existence of a fact cannot be inferred from circumstantial evidence unless such evidence is serious, precise and consistent. According to ECHR case-law, evidence as a whole must be evaluated fairly, otherwise, there is a violation of Convention Article 6.
Indeed. This is how it is supposed to work in all civilized countries with the rule of law. When a case is made up entirely of circumstantial evidence (which many are), the trier of fact is to assess each piece of circumstantial evidence for reliability and evidentiary value, if any, as against the accused. This is not even remotely close to requiring proof BARD with respect to each piece of evidence, as some PGP suggest. It is simply that they do not wish to understand the proper process for assessing pieces of evidence.
If any given piece of circumstantial evidence is unreliable or has no evidentiary value against the accused, then it should not be considered further when it ultimately comes time for the trier to fact to assess whether or not the totality of the pieces of reliable and probative evidence as a whole amount to proof BARD.
Hellmann nailed this, and his written judgment is the only one released yet in this case that passes juridical muster and demonstrates a proper appreciation of the law.
Moreover, circumstantial evidence is sufficient to warrant a conviction
only when it is consistent with the conclusion that the criminal act was committed by the accused AND that the facts are such as to be inconsistent with
any other rational conclusion other than that the accused in the guilty party. That is to say, the test for conviction based on circumstantial evidence is that the trier of fact must be satisfied BARD that the
only rational inference that can be drawn by the circumstantial evidence is that the accused is guilty.
This has been the law for a long, long time here in Canada, and it is supposed to be law in Italy as well. The elements of an offence have to be established BARD, and while an element of an offence can be based on circumstantial evidence, that is only so when a trier of fact is satisfied BARD that the guilt of the accused is the
only reasonable inference to be drawn from the
proven facts. The proven facts are those that have survived scrutiny in the initial assessment of the evidence (for reliability and evidentiary value, etc., as noted above). Reliance on irrational or speculative evidence to support an inference of guilt is not appropriate, and cannot properly sustain a conviction.
