Queensland Racing Limited (QR) stewards have not yet fixed a date for the resumption of an inquiry into the running and handling of Baby Boom at the Sunshine Coast last month.
Former Victorian rider John Keating and Gold Coast trainer John Nikolic were questioned by stewards immediately after Baby Boom finished fourth as the $1.30 favourite in a Maiden Handicap (1000m) at Caloundra on January 3.
The inquiry was opened after stewards established that a large volume of money was placed on the horse to lose with betting agency Betfair.
Chief steward Wade Birch flew to Melbourne last week to interview a professional punter who also acts as a commission agent.
Nikolic and Keating, now based at Coffs Harbour, have been interviewed twice and been told they will be required again when the inquiry resumes.
At the initial inquiry, evidence was taken from Nikolic regarding his association with a Gold Coast punter who has declined requests from stewards to assist in their investigations.
Meanwhile, a directions hearing involving apprentice Daniel Ganderton and QR stewards will begin in the newly-formed Queensland Civil Administration Tribunal (QCAT) on Wednesday.
Neither Ganderton nor his master Paul Messara will be required to attend the hearing which will rule on the stewards' appeal against Ganderton being exonerated by Queensland's first level appeal body against a two-month suspension.
Ganderton, who will ride Blue Diamond Stakes favourite Beneteau at Caulfield on Saturday, was suspended by Queensland stewards following his ride on Deer Valley at the Gold Coast on January 2.
Stewards found the 21-year-old apprentice guilty of failing to take all reasonable and permissible measures to give the Steele Ryan-trained Deer Valley every chance when she finished sixth to the Gillian Heinrich-trained Sweepstaking.
No date has yet been announced for another appeal by stewards after jockey Ric McMahon had a three-month suspension overturned.
McMahon was initially suspended for improper riding on Haslington at the Gold Coast on Boxing Day.
The John Morrisey-trained Haslington finished third to Coming Up Trumps in a 1400-metre maiden.
Stewards expressed concern that McMahon allowed Haslington to shift away from the inside rail which gave Coming Up Trumps a run to his inside.
Haslington was beaten just over a length.
