Today marks an important chapter in the history of the Hong Kong Jockey Club as the inquiry into the trackwork fall of work rider Chan Kwok-leung reconvenes to hear the charges brought against trainer Alex Wong Siu-tan. This is no ordinary case, and not simply because of the serious injuries sustained by the 25-year-old when he fell from the Wong-trained The Young Treasure almost three weeks ago. It raises issues not only about a trainer's responsibility for his staff and the horses in his care, but also about the Club's role in those matters and the seemingly blurred lines between the two. And it raises wider issues about track safety and the training, supervision and allocation of work riders. The case already has the prospect of legal proceedings hanging over it, and Wong has taken legal advice since being charged, though he is not expected to have a lawyer present at today's inquiry. Whatever decision is reached may not prove to be the end of the matter, nor will it necessarily be reproduced if the case ever goes to court. The Club's rules do not require the level of proof or certainty demanded under the law - instead, the system stands or falls on the perceived fairness and consistency of its decision-making and the acceptance of those decisions by the parties bound by the rules. In this case, that means the Club must not be seen to be pinning the blame on Wong if more systematic problems contributed to Chan's fall - and Winfried Engelbrecht-Bresges, the Club's director of racing, has already promised a wider review if such doubts are raised by the inquiry. Wong has been charged with a breach of Rule 58 (i) (a), which states: 'Each trainer shall conduct his business properly with due regard to the interest of his owners and is responsible for the good management and training of horses in his charge.' And/or a breach of Rule 58 (i) (b), which states: 'Each trainer shall be responsible for all matters pertaining to the running of his stable including stable routine, feeding, security inside the stable and the work of his stable staff allocated to him.' Chiefly, the case appears to rest on Wong's training of The Young Treasure and whether Chan should have been riding a horse who had gained something of a notorious reputation. In this case, it could be argued that Wong was acting in the interest of The Young Treasure's owner by keeping the horse in training despite its troublesome nature. Does this amount to good or bad 'management or training of horses in his charge'? Training, as the term implies, goes beyond getting horses physically fit for racing, and there are countless examples of wayward horses going on to perform well on the racetrack after being 'trained' to change their behaviour. At what point should trainers give up on such horses? And if The Young Treasure was such a hopeless case, as some people have suggested, did the Club have some responsibility to take action itself? The issue of how work riders are assigned their duties is complicated by the fact that Hong Kong is unusual among major racing jurisdictions in that trainers do not appoint and train their own workforce. Instead, they are allocated staff from the Club's pool, though the rules still place the burden of responsibility on trainers for their work. But this case raises the question of where the trainer's responsibility ends, and the Club's begins? There are also questions that need to be answered which go beyond the individual aspects of this case. Was there any fault with the positioning or construction of the rail and post on to which the work rider fell? Are the provisions for the training and assessment of work riders adequate? Are there enough senior work riders to cope with troublesome horses? Do the lines of communication between trainers and the Club need to be improved over issues concerning work riders? Of course, horses are unpredictable animals and another possible conclusion could be that Chan's fall was simply an unavoidable accident. But for the sake of justice - not only under the rules of racing, but also natural and legal justice, and above all justice for Chan Kwok-leung - the Club has to ensure that it provides answers to all the questions raised by this case.
