Proportional Liability: Analytical and Comparative Perspectives

The application of this ‘all or nothing’ rule can lead to unfairness by absolving defendants who acted tortiously and may also create undesirable incentives that result in greater wrongful conduct and injustice to victims. Some courts have decided that this ‘no-liability’ outcome is undesirable. They have adopted rules of proportional liability that compensate plaintiffs according to the probability that their harm was caused by the defendant’s tortious conduct.

In 2005 the Principles of European Tort Law (PETL) made a breakthrough in this regard by embracing rules of proportional liability. This project, building on PETL, endeavours to make further inquiries into the desirable scope of proportional liability and to offer a more detailed view of its meaning, implications, and ramifications.
