I want to clarify one or two points before I move on. My final question is for Dr. Singh. This process had its roots in the process described in July 2016. At what stage between July 2016 and 27 April 2017 did it come to light internally that there were discrepancies? Can Dr. Singh put a date on when the discrepancies became apparent in the documents from the State Pathologist and the PULSE system?
