Q

What is voluntary manslaughter?

A

Definition of murder appears to have been satisfied but one of two defences can be successfully pleaded. So, it has a specific partial defence. You can not be charged of voluntary manslaughter, charged of murder and if a defence is satisfied then the charge can be brought down to voluntary manslaughter.

Q

What is diminished responsibility?

A

Originally defined in s2 of Homicide Act 1957 and then is now defined in s52 of Coroners and Justice Act 2009. It is the idea that you can have your conviction downgraded if the defendant can prove (burden of proof) on a balance of probabilities. (R v Wilcocks (2016))

Q

How do we satisfy diminished responsibility? s.2(1)

A
  • D was suffering from abnormality of mental functioning.
  • Which is due to a recognised medical condition.
  • Which substantially impairs the D,s ability to: understand nature of conduct OR form rational judgement OR exercise self control.
  • The abnormality must provide explanation for D causing V’s death i.e there is a casual link between medical condition and the killing.
  • Intoxication may also be a factor
  • When there is unchallenged medical evidence, the judge should withdraw the charge of murder from the jury. (R v Brennan 2014)
