The Jockey Club had some serious thinking to do to ensure the latest jockey-drug embarrassment is never repeated, said executive director of racing Bill Nader. Nader (pictured) promised 'a systematic review' of procedures as the Doleuze case had clearly shown up a problem previously unconsidered. The director stopped short, however, of criticising any of his team and said an early laboratory test of the Bliss Sensory Pills might still not have saved the day. 'We spoke to [chief analyst] Terence Wan about this and he stands by his decision not to test the pills because of the variance that can take place on a batch-to-batch basis,' said Nader. 'Terence said just because one batch of a certain supplement tests clear, it doesn't mean the next one will. That's why he went by the list of ingredients published by the manufacturer. 'We'll all get together - racing control, the laboratory, the legal people and myself and work through the whole issue during the summer. The bottom line is we must uphold the integrity of the drug-testing protocols.'
