Explain in detail what actus reus and the chain of causation actually means.

The term actus reus is Latin for ‘the guilty act’. It is essential in criminal law, as actus reus must be there for their to be a criminal offence. It can mean a guilty act or an omission to act. In the crime of murder, then the actus reus would be the killing of a human being.

The act must be voluntary for the defendant to be guilty. For example, if the defendant acts out of reflex because of another force, it is not voluntary and the defendant cannot be found guilty. A good example can be found in the case of Hill v Baxter (1958) where a driver is being chased by a swarm of bees and driving a car in these conditions would be extremely hard so could not be held guilty for his actions.

If the defendant is to be found guilty of an offence then it is important to prove that the defendant caused the offence in the first place. This is the chain of causation, and means that there must be a clear and unbroken link between the conduct and the consequence. For example, if a defendant attacked a victim and the victim dies then the chain of causation has not been broken and the defendant is guilty of murder. However, if the defendant attacks the victim and the ambulance has a crash on the way to the hospital then the chain of causation has been broken. To see if the defendant is still to be found guilty we can take into account the ‘but for’ test. This decides ‘but for’ the action of the defendant, would the consequence still have happened. In this case, the answer is no as the victim wouldn’t have had to be taken to hospital ‘but for’ the actions of the defendant so he is still guilty. The courts are very reluctant to let the defendant off.

An example of the ‘but for’ rule is in the R V Pagett (1983) case. The defendant used his girlfriend as a human shield when firing at the police. The police returned fire and shot his girlfriend and killed her. He claimed that it was the police that had killed her and not him. He was found guilty of manslaughter as the result would not have happened ‘but for’ the actions of the defendant.

To break the chain of causation it would take actions of a third party intervening, the victim’s own contribution to the events or ...
