This document summarizes various concepts of liability law, including strict liability, absolute liability, and vicarious liability. It discusses key cases that established principles of strict liability, such as Rylands v. Fletcher. Absolute liability differs from strict liability in that it does not provide any exceptions. Vicarious liability holds one party liable for wrongful acts committed by another in certain relationships, such as between a master and servant. The document also examines liability of corporations and how they can be held criminally liable through principles of vicarious liability.
