Wasn’t the MM was the race where AB was stuck in a traffic jam for hours and races delayed for a hour?
Not implying anything but would any vet or any staff give a wrong medication or drink by mistake if the horse was agitated during the trip etc. If so would it be viewed as performance enhancing if given to calm a horse? I am just clutching at straws for the connection.
But you would expect corroboration from the vet.
In fact (I think) if a vet administers any substance to a racehorse there are protocols to be followed, records to be updated.
If you just say "OK" to any uncorroborated reason then you would open a whole Pandora's Box in regard to anyone charged in the future.
There is a precedent to a horse being allowed to keep a race after an abnormal sample.
Think it was one of Clarry Connor's Slipper winners. Tierce in 1991 perhaps? Lignocaine for a tooth?
