Proportional Liability as an Application of the Precautionary Principle. Comparative Analysis of the Italian Experience

Giovanni Comandé, Luca Nocco

Abstract


“All-or-nothing” rule is still the most used system to allocate damages in tort law. According to this principle, a judge must establish the minimum threshold beyond which causation is established and below which, on the contrary, a right to compensation may not exist. The article argues that proportional liability is a suitable option to substitute the “all-or-nothing” approach, especially in cases of (causal/scientific) uncertainty. The aim is to have a more flexible instrument in pursuing the traditional goals of tort law, i.e. compensation an deterrence, by means of a progressive precautionary approach according to which liability should be proportionally attributed in compliance with developments in scientific knowledge and evidence concerning general causation
