The filly, owned by Anthony Forde and trained by Francois Rohaut, was first home by a head from Special Duty, with Rohaut’s other runner Baine just a neck away in third.
After a 75-minute inquiry, Liliside was relegated to sixth place, with Special Duty promoted to first.
The latter had also been awarded the 1000 Guineas at Newmarket in the stewards’ room two weeks earlier after being narrowly beaten by Jacqueline Quest.
“Liliside is entered in the Sandringham (at Chantilly), but it may be a bit too close for her. There is also a race for her at Deauville in August, ” said Rohaut.
