voluntary manslaughter- diminished responsibility Flashcards
where was it defined
section 2 of the homicide act 1957, amended by the coroners justice act 2009
proof is on
the balance of probabilities
first rule
section 2 (1) states there must be an abnormality of mental functioning as in Byrne
second rule
the abnormality of functioning must arise from a recognised mental condition.Medical evidence is needed as in Bunch.2 medical proffessionals must agree on a condition as if they do then the defendant cannot be convicted of murder. Can be a mental or physical condition
third rule
the abnormality must substantially impair the defendants ability to either- undertsand the nature of their conduct, form a rational judgement or excersise self control
section 2 (A)
further defined by Lloyd and later Golds- as to substantially impair means more than trivial but need not be total
fourth rule
abnormality of mental functioning mujst provide an explanation for the killing.Need not be the only facor, but must be a significant factor
intoxication rules
Intoxication alone can not be used as an explanation as in Dowds. Wouldnt prevent an abnormality of mental functioning as providing an explanation for the killing however( dietschmann) Intoxication due to alcohol dependancy syndrome where the intoxication has affected their brain can provide an explanation (stewart/wood) If decided the intoxication caused the killing not the abnormality then they cant rely on the defence(joyce and kay)
