Definition of Defence in Criminal Law

In the realm of criminal law, the definition of defence is a critical concept that refers to the arguments and evidence presented by a defendant to show why they should not be held legally responsible for a crime. The purpose of a defence is to create reasonable doubt in the minds of the jury or judge, ultimately leading to a verdict of not guilty or a reduction in culpability. Defences can be categorized broadly into two types: justification and excuse. Justification defences argue that the act was not a crime under the circumstances (e.g., self-defense), while excuse defences assert that the defendant was not in a state to be held accountable (e.g., insanity). Each defence must be substantiated with evidence, and the burden of proof often rests on the defendant. Understanding the nuances of these defences can significantly influence the outcome of a criminal trial, showcasing the intricate balance between law and morality. This article will delve deep into the various types of defences, their historical evolution, and the practical implications in the courtroom.
