ABSTRACT
Sport incorporates the elements of a legal system. It is a rule-governed institution for regulating the conduct of human communities. Judicial officials in both contexts, in sport and in law, are called upon to examine evidence to identify important facts and to make decisions about what the laws or rules are or mean and how they are to be applied. A complete account that describes sport as, or at least compares it to, a legal system should also say something about the nature of rules in sport and may also need to consider the relevance of the work of legal theorists in explaining the nature of rules. Any systematic discussion of calls in sport should begin with a small philosophical puzzle. Tamba Nlandu’s arguments address the use of goal-line technology in soccer, but they can be applied generally to the use of technological aids to on-field officiating in all sports.
