Champion trainer Ivan Allan will appear before the stipendiary stewards at Happy Valley tonight in relation to the booking of French jockey Eric Legrix for Rainbow Star in the seventh event on the Grand National card. Legrix and retaining trainer Patrick Biancone were allegedly not consulted before the jockey was declared by Allan's assistant trainer in the champion's absence in Sydney for the Easter Sales. Chief stipendiary steward, Clinton P. Pitts Jnr, said yesterday: 'We will be talking to Mr Allan before the first race. 'I have received a report from Mr Biancone and we want to find out exactly what took place in relation to the booking of Legrix. Mr Biancone has consulted his owner, who has a horse in the same race, and Legrix remains on Rainbow Star.' Biancone runs the mare Aqua Princess who will be ridden by her regular rider Sheri P. W. Kong, the stable apprentice. Biancone said: 'I will always make Eric available to any trainer who asks and there are no exceptions. But if I have a horse running in the same race I will always ask the owner if he is agreeable to Eric riding against him. 'After all, it is the owner who pays the bills and he also pays part of Eric's retainer. 'If I had known that Eric was wanted for Rainbow Star - or if he had known - then I would have spoken to the owner of Aqua Princess and got his agreement before giving Eric permission,' explained Biancone. There was a possibility of Legrix being taken off the horse in the Classes Four and Five, 2,400-metre race if the owner of Aqua Princess, Chang Sau-man, had raised any objections, but he did not. Normal protocol, in relation to booking stable jockeys, is to ask the retaining trainer if the rider is available. If the jockey is directly asked, it is normal for him to refer the request to his trainer as he may also have had a request for the rider's services. However, there have been several examples of trainers putting in a declaration form and then phoning to find out from the steward on duty what jockeys remain available. A jockey is then declared, although he may not have been asked if he wished to ride the horse in question. A recent case involved English rider Philip Robinson, who was declared to ride Genuine Pearls by trainer Gary Ng Ting-keung. Robinson had not been asked, could not do the weight and a substitute rider had to be put up. Allan, en route to Hong Kong from the Sydney sales, was not available for comment last night.
