Legal liability has various forms, including the various distin-guishable forms of liability related to the world of sport and disciplinary li-ability in sports in particular, which can also be discussed by comparing it with aspects of criminal law and labour law. Disciplinary liability in sports emerges in the case of accountable, delinquent infringement of the related regulations. The burden of production of evidence lies with the sports federa-tion. Every sports federation is authorised to conduct disciplinary proceed-ings against an athlete, sports specialist and sports organisation involved in the competition system of the given sports federation.The disciplinary regulations defi ne what disciplinary offence the athlete, sports specialist or sports organisation is likely to have committed, for theinvestigation of which the proceedings will start. Both the legal standards of the country concerned and the rules of national sports federations include detailed regulations necessary for disciplinary proceedings to be conducted properly. The knowledge of thereof is essential in terms of practical applica-bility, as presented by this study in detail.
