The courts accepted Stefanoni's reports. Crini successfully argued at the Nencini merits court that C& V’s report had been full of references to American standards which led to specious claims by the defence that Stefanoni had not followed ‘international standards’ : it is noted.
The Italian Scientific Police follow the guidelines of the ENFSI – the European Network Forensic Science Institutes. Dr Stefanoni observed that they followed these specific guidelines whereas Conti and Vecchiotti basically picked and mixed a random selection of international opinions:
“We followed the guidelines of the ENFSI, theirs is just a collage of different international opinions”.
The Chieffi Court (Supreme Court) The next level of appeal court overturned completely Hellman’s findings. It rebutted that the DNA sample of Meredith’s was ipso facto low quality just because it was LCN. ‘The experts’ had claimed, relying on their US sources that LCN sampling should only be done on special projects, such as missing persons or cadaver identification, and that there was not the technology as it was ‘too innovative’. Chieffi did not buy this, pointing to embryology studies. He scoffed at the idea of ‘the experts’ being more expert than Professor Novelli or Dr Torricelli. He censured Hellmann for failing to consider their equivalent expert knowledge. Chieffi was particularly critical of ‘the experts’ refusing to test the remaining knife sample, calling their reasoning, ‘intellectually dishonest’. 25 March 2013, Chieffi ordered the case back to the Appeal court to consider the DNA evidence again, amongst other issues, and that the knife sample be tested. One suspects ‘the experts’ were loath to test the sample in case it turned out be further DNA of Meredith, and this may be why Chieffi smelt a rat.
The Nencini Court (Appeal Court) Nencini made it clear in a newspaper interview it was not within his remit to criticise ‘the experts’, but rather, to assess the legal rectitude of the Massei court decision, which Hellmann patently failed to do. However, criticise he does. He directs to Barni that ‘no US standards’ are to be quoted. In upholding the findings of the Massei court he makes the following point in his reasoning about the DNA of the knife and bra clasp: He upholds that the Forensic Police, aside from some human error, acted correctly and dismissed defence claims that Stefanoni had withheld raw data, and as claimed by ‘the experts’, citing documentary proof the information had been deposited. Nencini reinstated the convictions, 31 January 2014, and dismissed the claim of contamination. The sample on the knife ‘the experts’ had claimed was ‘starch’ and ‘too low LCN’ was successfully tested and found to be that of Amanda Knox.
The claim it was contaminated was Marasca-Bruno pulling it out of thin air, a claim which was never tried, tested, cross-examined nor proven in a merits or Appeal Court. The reason the pair were acquitted was thanks to interference from outside the court.
