Interpreting the Contours of Self-Defence within the Boundaries of the Rule of Law, the Common Law and Human Rights

Abstract

The Crime and Courts Act 2013 has amended s. 76 of the Criminal Justice and Immigration Act 2008 on the amount of force a person can use in self-defence. The amended provision poses a dilemma for the courts: it states that only reasonable force can be used by a householder against a trespasser, but adds that force is unreasonable if it is grossly disproportionate. Until now, the courts have treated reasonable force and proportionate force as synonyms. This article suggests that the amended s. 76 should be interpreted to comply with the rule of law, incorporating the idea of equality before the law and legality. The courts should respect the traditional common law concept of reasonableness which is an impartial, objective concept that plays an important role across the whole of the criminal legal system. In addition, the article points out that the Act must be interpreted, where possible, in accordance with the European Convention on Human Rights to avoid the problems that arose with the defence of lawful chastisement.
