it is an error to assume that Woodford invested due to the research testing going on in FL. The paperwork for the investment from Woodford was initiated before any reports were given by Penon and was done in the context of IH supporting other work.
It does not appear that the "reports" by Penon where even data that he took himself in his required role as an ERV but he only relayed information he received from Rossi.
The "acceptance" of the 3 reports (if it actually was and "acceptance" and not just a receiving) was done before the work in FL was claimed as the GPT. IH saw no need in "rejecting" them as the GPT since they were not claimed to be that when they were submitted. It was not until later that Rossi started to claim that the work in FL was the GPT. Until then there was no need to officially accept or reject the report.
