Recently, technology has impacted upon sports umpiring and refereeing. One effect is that the means to make sound judgments has becoe ‘distributed’ to new groups of people such as TV viewers and commentators. The result is that justice on the sports field is often seen not to be done and the readiness to question umpires' decisions that once pertained only to the players and, in some sports, to the crowd, has spread to anyone who has a television. What is more, (...) the questioning can now be done on good grounds. This change is explained and a way of thinking about it is put forward. The aim is to develop a theory of the relationship between human match officials and technology. Toward this end I offer a new terminology for the kinds of justice that are involved in match officiating. I argue that the introduction of new technology should be done in such a way as to maintain the justice of decisions and that justice is not the same as accuracy. Justice is best served with a restrained use of new technology. (shrink)
