To illustrate, if X gets mesothelioma from exposure at work, and he has worked for companies A Ltd., B Ltd., and C Ltd., each of which materially increased the risk of mesothelioma occurring in him, then X can choose any of the companies to sue. Suppose X sues C Ltd., then the court will award to X, and order C Ltd. to pay, damages totalling compensation for all of the loss he has suffered due to mesothelioma (i.e. 100%). Thereafter, C Ltd. can bring proceedings against A Ltd. and B Ltd., demanding from each a payment of a proportion of the total damages C was ordered to pay to X, corresponding to the proportion by which each company increased the risk of mesothelioma of the total increase in risk in X.
