This chapter considers instances where ICT applications cause physical, material, economic, or emotional harm, with a focus on third party liability or tort law. The chapter should be read as an important example of how private law liability may step in to deter the development, sale, or usage of faulty ICT. It discusses the relevant legal conditions of damage, causation, fault liability, and strict liability, ending with questions around compensation and deterrence as the overarching goals of tort law.
