The Legal Definition of Murder

In English law, murder is committed when a person of sound mind unlawfully kills another human being with the intent to kill or the intent to cause grievous bodily harm (GBH). Because the intent to cause "really serious injury" is sufficient for a murder conviction, many cases hinge on the defendant’s state of mind at the exact moment of the act.

To secure a conviction, the prosecution must prove that the defendant’s actions were a "substantial" cause of death. Our defence often involves challenging the causation—was there an intervening act, such as medical negligence or a pre-existing condition, that was the true cause of death?

Understanding Manslaughter

Manslaughter is a diverse category of homicide that applies when a killing is unlawful but lacks the specific "malice aforethought" required for murder, or where a partial defence applies. It is divided into two main types:

1. Voluntary Manslaughter

This occurs when the elements of murder are present, but the defendant’s responsibility is reduced by one of three partial defences:

• Diminished Responsibility: An abnormality of mental functioning (arising from a recognised medical condition) that substantially impaired the defendant's ability to understand their conduct or exercise self-control.
• Loss of Control: A reaction to a "qualifying trigger" that would cause a person of the same age and sex, with a normal level of tolerance, to act in a similar way.
• Suicide Pact: Where a person kills another in pursuance of a settled agreement that they would both die.

2. Involuntary Manslaughter

This applies where there was no intent to kill or cause GBH, but the death was caused by:

• Unlawful and Dangerous Act: An intentional act that any sober and reasonable person would recognise as carrying a risk of some harm.
• Gross Negligence: A breach of a duty of care so severe that it is judged to be criminal (frequently seen in medical or workplace fatality cases).

Complete Defences to Homicide

A complete defence results in a full acquittal (Not Guilty). We meticulously investigate the viability of:

• Self-Defence: Using reasonable and proportionate force to protect yourself or another.
• Automatism: Acting without any conscious control due to an external factor (e.g., a medical episode).
• Insanity: A "defect of reason" arising from a disease of the mind, such that the defendant did not know what they were doing or that it was wrong.
• Mistake: Acting under an honest (even if unreasonable) belief that made the use of force necessary.

Attempted Murder

Attempted murder is technically harder for the prosecution to prove than murder itself. For murder, an intent to cause GBH is enough. For Attempted Murder, the prosecution must prove a specific intent to kill. This distinction is a primary area of challenge for our defence team in the early stages of a case.
