Bruce - since you asked so politely, here is some additional communication from Mr. Weigelt on said subject:
"The IVA Conference Centre is an independent business unit that sells its services on the open market. Even though the Conference Centre shares our name, the majority of its clients are not connected with IVA .The organizations using our centre are responsible for their own content. That said, we are aware of the risk that some customers may try to exploit our brand for supporting their events and gain credibility by association. This is obviously extra important when it comes to issues as science fraud. Therefore, the policies of our Conference Centre clearly guides to exclude events in conflict with the Academy statutes (to promote technical and economical sciences) and we always perform background checks on new customers.
This time, the venue was booked by Mats Lewan for a “technical presentation by a US company with international guests”. Our Conference Centre staff did not have knowledge in advance of the conference that that Mr Rossi was among the speakers, and the background check on Mr Lewan himself did not reveal anything suspicious. Directly after the event we were made aware of what had happened and took actions to mitigate any potential damages. We contacted media to make it clear that the claims made by Rossi are in no way endorsed by the Academy. Mats Lewan is red-flagged for future reservations in our Conference Centre, and would not have had access of our conference centre had we known the content of the event. It is clear that we need to review our procedures to avoid similar incidents in the future."
