The defence of loss of control is defined in the coroners and justice act 2009 as a total loss of the defendants powers of reasoning that was caused by a qualifying trigger.
Loss of control must be TOTAL, not partial or a state of confusion.
Qualifying trigger: Genuine fear of serious violence The fear must be that the defendant or someone close to D believes they will be inflicted with serious violence by the victim. Only the defendant has to believe in the fear unless proven ingenuine.
Qualifying trigger: things said or done Things said or done must amount to 'extremely grave nature' and causes the defendant to lose complete control.
A-G jersey and Holey state the reasonable person test for things said or done, as would a reasonable person of the defendants sex and age, with normal tolerance, have lost control in the same situation
A delay used to not be allowed for loss of control, YET Ahlwalia states that now it can be the defendant 'building up' to comitting the offence.
You cannot claim loss of control if it is used due to, revenge, sexual infidelity, D as the agressor.
The sentence for a sucessful defence in Loss of control is voluntary manslaughter.
