Victorian officials declared the wrong horse a winner before correcting the error prior to declaring correct weight at Bendigo on Friday.
The incident occurred in the Silks Function Centre BM64 Handicap (2200m).
After reviewing the photo finish, Archery Peak was declared the winner with House Of Stars and Look At Me Now dead-heating for second.
Due to the closeness of the finish the photo was reviewed prior to the chief steward declaring correct weight and it was identified that the deceiving photo had in fact tricked officials.
"Geoff Hausfeld, one of our senior stewards, was weighing the riders back in as we do after each race," chief steward Terry Bailey told Racing Victoria.
"Looking at the photo finish, he wasn't totally happy with it.
"He took the initiative to go the judges' box and double check it, and that's where the error was determined.
"We can bless our lucky stars it was picked up at the right time, and that was prior to correct weight."
Stewards amended the final placings to be House of Stars ($31) first ahead of Look At Me Now ($4.40 fav) in second and Archery Peak ($5.50) third.
Corporate bookie Sportbet declared a "justice payout" and paid winning tickets on Archery Peak with bonus bets.
