Jockey Club officials have refused to enter into a slanging match with top trainer Ivan Allan following his comments on Wednesday over the Cheers Hong Kong inquiry. Allan lambasted what he described as an 'amateurish' inquiry into the horse's Isosorbide positive and was particularly critical of chief stipendiary steward Jamie Stier, but Jockey Club director of racing Winfried Engelbrecht-Bresges said yesterday the club had no plans to respond at this stage. 'The inquiry Ivan Allan has criticised is ongoing and we believe it is therefore inappropriate for anyone to be making comment on it in the media like this,' he said. 'There are correct procedures for inquiries and we plan to respect those procedures.' The inquiry into the presence of Isosorbide in a sample taken from Cheers Hong Kong before he was withdrawn from the Hong Kong Gold Cup on February 23, was adjourned on Wednesday at Allan's request after he was charged under rules dealing with a trainer's responsibility to present horses drug-free for racing. Allan entered a not guilty plea then asked for an adjournment to consider the body of evidence. Engelbrecht-Bresges said he was surprised at the trainer's outburst 'as there has been no decision on his guilt or innocence at this stage'. He added: 'If he is in fact found guilty and is unhappy about the inquiry procedures, then that is why we have an appeal process to enable any licensed person to air those sorts of grievances.' On the track, Allan turned up with his first griffin winner for the season and has in mind to do to Scintillation what some officials at the Jockey Club would liked to have done to him after his barrage this week. 'Scintillation needs to be given time and needs gelding,' Allan said. 'He won nicely today, I'm happy with that, but he will come back better next season and I expect him to improve when he gets over more ground later.' The colt, whose granddam is a three-quarter sister to English Derby winner Slip Anchor, gave Weichong Marwing the first leg of a double he would complete late in the afternoon on Joy Fay Fay.
