As the second rank outsider, Ethical Dilemma ($41) settled near the rear in a hot field that had Galenus start favourite ($2.05) ahead of the promising Coronation Keith ($3), along with this season's Newmarket handicap winner Deroche ($4 out to $5.50).
It was a sizzling tempo early with Galenus and Deroche sharing the lead ahead of Coronation Keith with Liffeybeau caught three-wide for most of the trip.
While the favourites were cutting at each other, rider Bulent Muhcu must have had a smile on his face as wide as the Mowbray straight when he eased his charge to challenge over the final 200 metres.
In the space of 100 metres Ethical Dilemma had the leaders covered and he went on to win convincingly from the other outsider Geegee Trendsetter ($51) with Deroche hanging on for third ahead of the fast-finishing Gee Gee Secondover.
Peter Luttrell also celebrated an emotional win when his five-year-old Military Law scored a game win in a class one over 1420m.
"I've had a few issues I had to sort out with this horse but he's as good as gold now.
"I've always had an opinion of this horse and I'm confident he will win more races this time in and it's so good to see him doing what I've always believed he could."
