 In this context the basic questions concerning causation in the law are: (i) what are the criteria in law for deciding whether one action or event has caused another (generally harmful) event; (ii) whether and to what extent causation in legal contexts differs from causation outside the law, for example, in science and everyday life; and (iii) what reason(s) (presumably based in the law’s use of causation to attribute responsibility) explain and/or justify such differences as may be found to exist.
