This article covers the topic of the grounds for civil liability in the case of injuries suffered while doing sports. This issue is very important, as injuries constitute an inherent element of physical activity. The focus of the article is on a tort liability. It is pointed out that the act has to be fi rst recognised as unlawful to be considered a tort. That is why the article tries to answer the question, which behaviours should be considered illegal. This is infl uenced by such issues as: the breach of sports rules, the consent of an injured person, and the situation where such person acts at his/ her own risk.
