Loss of control is a partial defence to murder, and where successful will decrease a charge to voluntary manslaughter
Included in s.54 (1) of the coroners and justice act
the first rule is that there must be a total loss of control, not partial as in R V Jewel
Under s52(2) the loss of self control doesn't have to be sudden, different to old case of R V Ahluwalia
The second rule is that there must be a qualifying trigger this can be either fear ofviolence or things done or said
In terms of fear of violence, subjective test to prove the loss of control was due to this. In R V Dawes, there was no fear so it wasn't allowed
s55(4) things done or said must a)come from an extremely grave character, and b) gives the D a justifiable sense of feeling wronged this is objective, for the jury to decide. The case for this is R V Zebedee
The third rule is the objtest: this brings the question as to whether a person of the same age and sex as the D would've acted in the same way as D under the samecircumstancess54(1)(c)
The rules on sexual infidelity s55(6) (c) this will not be allowed- diregarded
Revnege: Under s54(4), the defence is not allowed if D acted in revenge. So if D considered revenge, not allowed as in Ibrahams and Gregory.
