This document discusses various general defenses that can be raised against tort claims, including act of god, volenti non fit injuria (willingness does not make injury), plaintiff's default, and private defence. It provides details on the essential elements and sample case laws for each defense. The act of god defense applies when damage is caused by natural forces beyond the defendant's control. Volenti non fit injuria is consent by the plaintiff to the harm. Plaintiff's default means the plaintiff was at fault for their own losses. Private defence allows reasonable force to protect one's body or property from imminent threats.
