What is the effect of intervening act on contract damage under English law?

Under English law, an intervening act is a factor that interrupts the chain of causation between a breach of contract and the resulting damages. This means that if an intervening act occurs, the party who has suffered a breach of contract may not be able to recover all of the damages they are owed. For example, if a party breaches a contract but then an intervening act occurs which causes further damage, the breaching party may not be liable for the additional damages caused by the intervening act.
