The concept of no fault liability in tort law holds people responsible for harm caused to others, even if they didn't do anything wrong. There are two main types: strict liability and absolute liability. Strict liability applies when a dangerous thing causes harm or land is used in a non-natural way, with some defenses available. Absolute liability, on the other hand, offers no defenses - if the criteria are met, the person is held liable. This concept is important for developing countries like India to understand and implement as they progress.
