Maybe the judges just determined this was \'race riding\' and has been part of the game for centuries.
As a gambler, you can yell and scream \"MAKE THAT CHANGE\" but when judges alter results, they tend to keep altering results and more and more races down the line get tampered with. Forgetting about individual specific races for example, it really comes down to how quick do we want our judges to be with their trigger finger. Since i don\'t really trust politially appointed hacks to begin with, i\'d prefer they generally not tamper with physical results, a \'wrong dq\' is more damaging than not putting up a horse who physically lost.
With \'quick trigger finger\' judges, its only a matter of time before they rob your legit winner and pay someone else.
