I seem to recall a comment from Chris Mellas at P-S to the effect that they were given only a few hours notice and could not attend. However, Dr. Potenza was a consultant for Mr. Sollecito. From a machine translation of his report: "On the kitchen knife seized in the apartment of Raffaele Sollecito there are no biological traces due to the above mentioned, having to be ruled out that the use made of it in the period before its evidence collection. Furthermore, none of the two samples was subjected to the investigation before for the search of human blood while the analysis of the DNA of these has provided, as mentioned, the amplification products extremely weak in intensity and considerably below the minimum limit recommended by the recommendations of GEFI (Italian Group Pathologists Porensi) but above were obtained in the various amplifications performed on the two samples incomplete profiles and with buoyancy allelic differences for some loci, such as not to allow a correct use of these results at the end of forensics, state not uniquely interpretable and theoretically even due to analytical artifacts."
RoseMontague will undoubtedly remember more than I do.
Quite often, a party refuses to attend, so that later they can then try to sabotage proceedings by claiming their expert was not there.
If it is "too short notice", he should have made an application to postpone to a more convenient date.
