What is a qualifying trigger?
s55 sets out a number of criteria which will count as suitable triggers for the defence.
D's fear of serious violence from V against D or another (Ahluwalia)/(Martin Anthony)
A thing said or done which (R v Doughty):
Constituted grave circumstances; and
Caused D to have a justified sense of being wronged
Can be combination of 1. and 2.
What is NOT a qualifying trigger?
Non-triggers:
Sexual infidelity (cheating) - Ibrams and Gregory
Pre-planned revenge - Baillie
What is the standard of self control?
"a normal person of D's sex, age, and normal degree of tolerance" (Camplin)
If it can be shown that such a person would have acted in a similar or same way it shows a measurable standard.
"Normal person" - (Hill).
More individual circumstances can be used to show reason for provocation but not standards of self control (Gregson).
