“Novus actus interveniens” is a Latin term used in law that means “a new intervening act” in English. This term is used to refer to a new and unforeseeable event or action that occurs after an initial act or event and interrupts the chain of causation. In legal discussions, novus actus interveniens is often used to argue that the original action or event should not be held responsible for the consequences because the new intervening act was the primary cause of the outcome. This concept is especially relevant in the context of tort law, criminal law, and discussions related to causation in different legal systems.
