Key Principles Across Homicide and Violent Crimes

Murder vs. Manslaughter:

Murder requires intent to kill or cause grievous bodily harm.

Manslaughter may arise from unlawful acts or gross negligence without intent to kill.

Gross Negligence Manslaughter:

Duty of care, breach, and death result in criminal liability.

Applicable to professionals (e.g., doctors) and ordinary citizens.

Recklessness and Oblique Intent:

Reckless acts causing death can lead to manslaughter.

Oblique intent suffices for murder if death or serious injury is virtually certain.

Assault and Consent:

Consent cannot justify serious bodily harm.

Both physical and psychological harm can form the basis of violent crime offences.

Proportionality:

Self-defence or defence of property must be reasonable and proportionate. Excessive force can convert defence into criminal liability.
