That has to be the case. The stewards' report doesn't stack up. If the gates had in fact opened spontaneously without being activated by the starter, for serious health and safety reasons, they surely could not have restarted the race, nor continued the meeting without the fault being determined and corrected. Testing that the gates opened when activated before doing so would not eliminate the risk of that happening again. So, I think either the report must be inaccurate, or they've continued the meeting on a very risky basis. Whichever, neither is a good look imo.
