Principle

CRIMINAL LAW — Defences — Insanity — Abnormal Behaviour Distinguished from Insanity

Area of law: CRIMINAL LAW
Court: Supreme Court

Abnormal behaviour alone does not prove insanity. The principle applies to criminal law. The defence must adduce medical or expert evidence. The rule prevents confusion between mental illness and unusual conduct. The court will require proper proof of insanity. The principle is well-established.
