Loss of Control and diminished responsibility are special defences. The defences merely reduces liability.
Where D kills V with malice aforethought, but the killing occurs due to:
loss of control; or
diminished responsibility
Loss of control set out in s.54 of the CORONERS AND JUSTICE ACT 2009:
D must have lost self-control and this caused the killing. There must be a loss of self-control, not just self-restraint: COCKER. The killing must have arisen from a loss of self-control and not from a ‘considered desire for revenge’: s.54
Loss of control set out in s.54 of the CORONERS AND JUSTICE ACT 2009:
2. D’s loss of self-control must have had a qualifying trigger
D’s fear of serious violence from V against D or another identified person: s.55
things done and/or said which were extremely grave and caused D to have a justifiable sense of being seriously wronged: s.55
Loss of control set out in s.54 of the CORONERS AND JUSTICE ACT 2009:
3. It must be that a person of D’s sex and age, with a normal degree of tolerance and self-restraint and in the circumstances of D, might have reacted in the same or similar way to D. So, things that made D lose control more easily, such as being drunk suffering from depression, or being aggressive by nature, are ignored.
Diminished responsibility set out in s.2 of the HOMICIDE ACT 1957 as amended by the CORONERS AND JUSTICEACT2009:
D must have suffered from an abnormality of mental functioning: BYRNE
Diminished responsibility set out in s.2 of the HOMICIDE ACT 1957 as amended by the CORONERS AND JUSTICE ACT 2009:

This covers:
severe depression
paranoia
Diminished responsibility set out in s.2 of the HOMICIDE ACT 1957 as amended by the CORONERS AND JUSTICE ACT 2009:
3. D’s abnormality of mental functioning must have substantially impaired D’s ability to:
Understand the nature of his conduct; or
Form a rational judgement; or
Exercise self-control.
The impairment needs to be significant: GOLDS
Diminished responsibility set out in s.2 of the HOMICIDE ACT 1957 as amended by the CORONERS AND JUSTICE ACT 2009:
4. Finally, D must prove that his abnormality of mental functioning provides an explanation for his conduct in doing or being a party to the killing.
