Each Concentrate revision guide is packed with essential information, key cases, revision tips, exam Q&As, and more. Concentrates show you what to expect in a law exam, what examiners are looking for, and how to achieve extra marks. This chapter examines the defences of consent; self-defence (which includes using reasonable force in the defence of oneself, defence of others, of property, and the prevention of crime); and duress (which consists of being compelled to commit a crime to avoid death or serious harm in a situation of immediacy where there is no route of escape). Duress is an excusatory defence; consent and self-defence are justificatory defences. If the defence of necessity does exist separately to the defence of duress, it is a justificatory defence.
