Q

The current situation
a person may use such force as is (objectively) reasonable in the circumstances as he (subjectively) believes them to be

16
Q

there have still been cases where court held no SD because D did not walk away - proportionality vs necessity

There are situations in which the only proportionate response is to ‘take a step backwards and walk away’

A

Brooks v DPP

Aznaag v CPS

17
Q

circumstances may justify a pre-emptive strike (about to be attacked)

A

Beckford

18
Q

Should not deny someone opportunity to prepare themselves immediately before an attack. If the preparation is for a lawful purpose - no more than necessary and to protect against attack then it is fine

A

AG’s Ref (No 2 of 1983)

19
Q

Householder cases - if D has gone completely over the top, these actions would be grossly disproportionate (unless there was some material reason to show otherwise)

A

R (Collins)

20
Q

Householder cases:
Was the degree of force grossly disproportionate in the circumstances as D believed them to be?
If no, was the degree of force used reasonable in the circumstances as D believed them to be?
Duty to retreat is important in distinction between proportionate and grossly disproportionate.

A

R (Collins) v Sec of State for Justice

21
Q

Mistake and SD - SD is available provided the belief about need for force is honestly held

A

Williams

22
Q

the subjective approach to mistake and SD is not problematic, it has been suggested that juries can be trusted and it has not led to too many people using the defence successfully and wrongfully.

A

Beckford

23
Q

Intoxication and Mistake - defence not open to someone who makes a mistake about need for force due to voluntary intoxication

A

O’Grady

24
Q

Murder and Excessive force

- SD either succeeds or fails (all or nothing)

A

Palmer

25
Q

If SD fails, there is no protection at all. Should we consider reducing to manslaughter if SD fails due to unreasonable force

disagrees with above - not for judicial decision to decide about manslaughter - if there was an intention to kill where is SD or not, cannot be manslaughter.

There is no alternative but to convict of murder. Lord here thinks that this should be left to Parliament

AG for NI’s Reference (No.1 of 1975)
