In England & Wales, the defence of self-defence provides for the right of people to act in a manner that would be otherwise unlawful in order to preserve the physical integrity of themselves or others or to prevent any crime.

In this essay I will be concentrating on two aspects of the law of self-defence in England and Wales, firstly the use of force in self-defence and the prevention of crime, and secondly why the law has been criticised in relation to people who confront intruders in their homes. Both characteristics have had a lot of criticism over the past few years with more and more people arguing that they should be able to defend themselves and their property from intruders without being charged for a reasonable attempt to safeguard their own.

Doubts about the system of self defence have been discussed by a host of critics, namely by Mr Noel Sweeney in 2000 where he raised criticism of an inherent fault of English jurisprudence stating that "self-defence" is an all-or-nothing defence in that if it succeeds the result is an acquittal and if it fails there is no other verdict but murder. A major case establishing this is R v Clegg1 where D, a soldier, had fired at a stolen car being driven towards him at a checkpoint and killed a passenger. The House of Lords confirmed his conviction for murder because the trial judge had found as a question of fact that the amount of force used was unreasonable and excessive.

The most up to date Law relating to self-defence can be found in Section 3 of the Criminal Law Act 1967;

This section provides a defence to a person who is using force to prevent a crime.

Section 3 states;

'1) A person may use such force as is reasonable in the circumstances in the prevention of crime, or in effecting or in assisting in the lawful arrest of offenders or suspected offenders or of persons unlawfully at large.

2) Subsection (1) above shall replace the rules of the common law on the question when force used for a purpose mentioned in the subsection is justified by that purpose.'2

This section would therefore apply as a defence where the defendant uses necessary and reasonable force to protect oneself and others, defence of one's property, preventing crime and assisting lawful arrest. This is controlled partly by common law and partly by section 3(1) of the Criminal Law Act 1967.

However, in some cases the defendant may be able to rely on both defences, for example, if the defendant is attacked by someone and reacts aggressively or with violence, the defendant may be able to depend on either defence and claim that his use of force was an attempt to prevent further attacks being inflicted on him and would therefore fall under s.3. At common law he could argue that the defendant was acting in order to defend himself. One or both of these defences are in hand to someone who is protecting themselves from an attack to someone who is protecting someone else from harm or where someone who is protecting her own property from an intruder to someone who is protecting someone else's property from a burglar.

Despite the similarities two significant differences still remain within the two defences:3

Firstly, where the defendant is a child or is insane, therefore not acting unlawfully, s.3 does not apply, but even so common law self-defence does apply. Secondly the common law defence only applies if the defendant is acting in order to protect himself or herself and does not apply where he or she is acting in order to prevent an attack on another, but s.3 does.

Even so the key element in both defences of self defence remains the 'reasonableness of force used' which even today is somewhat perplexed and difficult to distinguish, for example it could be considered reasonable where a young lady stabbed a heavily built man who attacked her but on the other hand if the tables were turned it would be different situation. Therefore to establish whether the force applied was reasonable or excessive, the jury must consider all the circumstances of the case including the situation as the defendant believed to be in.

In assessing the reasonableness ...
