Inclusion of 'recognised medical
condition' due to 2006 Law Commission
Report: Murder, Manslaughter and
Infanticide
Incorporates Byrne into the
statutory definition
Burden of proof
Should it be on D?
Most other defences D need only
raise them and P must disprove
Breach of Art 6(2) - 'everyone
charged with a criminal offence
shall be presumed to be innocent
until proven guilty'?
Developmental immaturity
2006 report
Should under 18's
be included within
the definition of DR?
Evidence suggests frontal lobes of
the brain which are responsible for
self-control and controlling impulsive
behaviour do not mature until 14
Govt took the view that learning
disabilities and autism spectrum
disorders were suffiicient in the context
This is not the same and means that children as young as 10 can be
convicted of murder just because they have not reached a certain stage of
development
LC
LC proposed removal of loss of self control criteria completely as it is
recognised that women in abusive relationships may kill from 'a
combination of anger, fear, frustration and a sense of desperation'.
Only concession govt made was that it need not be sudden
It is probable that some abused women will be
unable to show loss of control so will not be able
to use the defence
Sexual infidelity
Provocation was
created largely to cover
this circumstance but it
is expressly
disregarded under s55
Fear of serious violence
Largely added to cover cases like
Clegg and Martin but proving loss of
control makes it difficult to use
Provocation
Was largely common law
Homicide Act 1957 set out some tests but was insufficient
Until Camplin (1978) the
reasonable man was
considered an adult regardless of D's age
Camplin also allowed the gravity of provocation
(now circumstances). This was a wider
consideration than circumstances
Morhall: Lords allowed
addiction to glue sniffing to be
considered in the gravity of
provocation
Grave character helps avoid
repugnant results (e.g Doughty)
especially with use of an objective test
for the justifiable element of the QT
