Queanbeyan trainer Todd Blowes said he was blindsided by a decision to move stable star Noble Boy to Sydney, robbing him of his best horse despite owning a 30 per cent stake.
Blowes told Racenet he was "absolutely shattered" when told the five-year-old gelding would be moving to Warwick Farm to join Clare Cunningham's stable.
"I've got the biggest share in him but the other owners decided to take him off me," Blowes told Racenet.
"When you put all their (ownership) percentages together they outweigh me.
"The disappointing thing is that two of the owners I've known for 20 plus years and the other one is a farrier who I have known for 15 years.
"Apparently they just decided he would be better off being trained in the city."
Noble Boy secured a slot in the $1.3 million Kosciuszko last year and has won more than $600,000 after 14 starts.
