You may have something important here, but does it apply to all police evidence?
Can it be possible that this is the first time that any judge has hired an independent DNA expert that ruled that the police DNA work was contaminated in 26 YEARS. I do not know the answer to this question.
Is hiring an independent DNA expert to evaluate the police DNA work unconstitutional, or just forbidden by the ISC, which does not seem to be bound by the constitution.
Hellmann seemed to think that he had the authority to hire an independent DNA expert to look at the police work: was he wrong?
Can judges hire experts to evaluate the police work in other scientific areas(?) and what happens if the police work is judged wrong or incorrect(?).
Is evaluating, or even questioning the police work, illegal?
I do not pretend to know how this independent expert thing works, but it seems to me that the ISC argument about endangering all the cases to 1986 if any police conclusion is wrong would apply to every other facet of forensic science and mean that no expert may ever question the basis or procedures of any evidence produced by the police.
Is this right or am I missing something?
I would appreciate any feedback.

I don't think the ISC is saying that it is unconstitutional for Hellmann to have done what he did, it's saying that Hellmann shouldn't have subordinated the authority of the court to the analysis.
Maybe I am wrong on that. Others can weigh in if I am.
The ISC makes a weird sort of internal sense... because this business of a court "subordinating its authority" to some outside group does not seem to matter if that "outside group" is itself somehow tied to the court, as the Scientific Police (Stefanoni's lab) is to the public ministers (the prosecutor's, who hold similar rank to judges).
The bias of the ISC seems to be that if some group independent to the court (like Conti-Vecchiotti) is going to challenge the work of (not just a court appointed, but) a court affiliated group like the S.P., then the burden of proof is reversed, that this outside group needs to show the method of contamination, not just offer an opinion on the integrity of contamination/testing protocols of the court-affiliated group.
The other thing I have been missing is that the ISC did not invalidate the work of Conti-Vecchiotti, per se. In fact the whole reason for the testing of Sample 36I starts with the ISC, who in March blames Conti-Vecchiotti as well as the Hellmann court for not testing it.
This was, allegedly, one of the "lapses of logic" that Hellmann committed in the eyes of the First Penal Panel of the ISC.
2.2.4 Lack of reasoning in the decree of 7.9.2011 rejecting new appraisal
requested by the prosecutor, contradictory and manifestly lack of logic of
the judgment on this point: the Court denied the testing of the new trace
found on the knife by the experts Vecchiotti and Conti, on the basis of a
scientific judgment (smallness of the specimen) in stark contrast to the
initial theme of investigation and especially disconnected from the
evolution of the instrumentation used for this purpose.
In the course of their investigations, the appointed experts found a third
trace on the blade of the knife that had been seized in Sollecito's house
(Exhibit 36), in addition to the one attributed to Knox and one which was
attributed under strong objections to the victim, very close to the trace of
DNA extracted and attributed to the latter. This trace was not subjected to
genetic analysis – through a decision made by one of the experts, Professor
Vecchiotti, alone, without documented prior authorization to that effect by
the Court, who had also given a mandate to attribute the DNA on the
present findings on the knife and on the bra hook- because the amount was
not sufficient to provide a reliable result, amounting to Law (sic) Copy
Number. This choice, however, met the subsequent sharing of the group, on
the assumption that such a small sample would not have allowed two
amplifications necessary for a reliable result (p. 84 of sentence).
The ISC's objection, part of the quashing of acquittals, was that the prosecution at the Hellmann trial demanded testing of 36I and were (illogically acc. to the ISC) denied.
Ok. It's now been tested. It went the defence's way. Nencini STILL convicted.
It must be concluded that the decision is flawed to reject the request of
the Prosecutor General and the defenses of the civil parties, to complete
expert examination, with subjection to analysis of the new trace detected on
the blade of the knife found in Sollecito's house,.......
On this point, the complaints are well founded, since the survey once
prepared, must be complete and must therefore, without fear and without a
priori closures, bring to analysis also the newly sampled trace, according to
the most accurate and modern “experimental” analytical techniques, under
pain of violation of the law for not making a decisive test and the fallout in
terms of manifest illogical reasoning (again for obvious incompleteness of
the inferential platform, to have overlooked data that is not only important,
but crucial), as was correctly pointed out by the public plaintiff
Ok, it's done. The illogic of Hellmann is now logic. The trace belongs to Knox. No trace of Meredith is on that knife; at least no trace that can be attributed to murder.
The ISC is trying to uphold, though, that the Courts are the interpretors of DNA evidence, not the experts, and particularly if the court is going to subordinate it's authority to an independent expert, then that independent expert has to go the extra mile and.....
- prove contamination
- rather than simply demonstrate that proper anti-contaminations protocols were not followed, and that testing methods were substandard.
That's it in a nutshell.
