Breaking the chain (or novus actus interveniens, literally new intervening act) refers in English law to the idea that causal connections are deemed to finish. Even if the defendant can be shown to have acted negligently, there will be no liability if some new intervening act breaks the chain of causation between that negligence and the loss or damage sustained by the claimant.
