Apprentice Anthony Allen will vigorously defend a charge of excessively reducing the speed of a race when he fronts an adjourned inquiry into a race at Doomben.
On Saturday, Racing Queensland stewards charged Allen under the little-used Australian Racing rule 137 (d) which relates to a jockey slowing the pace of a race too much.
It is believed to be the first time the charge has been used in Queensland but in NSW and Victoria about six jockeys have been prosecuted under since 2005.
The most controversial was when champion jockey Damien Oliver was outed for 11 meetings for a ride on Elite Elle at Moonee Valley in October 2012.
Oliver successfully appealed the suspension.
Stewards opened the inquiry after the running of the Class 6 (1200m) and charged Allen who pleaded not guilty.
Chairman of stewards Daniel Aurisch said stewards believed Allen on the leader Pure Whisper excessively reduced the pace between the 800m and 600m.
He said it resulted in My Quilter (Sam Payne), Sezwho (Luke Tarrant), Nakanai (Rikki Jamieson), Daneodin (Priscilla Schmidt) and Heart of Many (Chris Munce) all being checked to varying degrees.
Allen said he did not believe he had done anything wrong.
"I see the same kind of thing when the pace slows in races three to four times a day. I want to defend the charge," Allen told stewards.
Aurisch then adjourned the inquiry to allow Allen to speak with his master Steele Ryan and for stewards to analyse sectional times for the race.
The inquiry will resume on Monday.
