Homicide Law and Defences Flashcards
What are the two critical factors to consider for a charge or Murder?
Whether the offender intended to;
-Kill the person OR
-Cause bodily injury that the offender knew was likely to caue death
Define homicide
the killing of a human being by another human being, directly or indirectly, by any means whatsoever
What are some examples of where manlaughter would be appropriate?
-Failed to get an ill or injured person to medical treatment
-Driving while intoxicated or incapable and killing someone
Murray Wright Ltd
Because the killing must be done by a human being, an organisation (Such as a hospital or food company) cannot be convicted as the principal offender
In relation to manslaughter and murder, what can an organisation be convicted of?
Manslaughter: parties to the offence
Murder: Cannot be convicted as either the principal offender or a party, this is because the offence carries a mandatory life sentence
When does a child become a human being?
When it has completely proceeded in a living state from the body of its mother, whether it has breathed or not, whether it has independant circulation or not, whether the navel string is severed or not
When does the killing of a child become homicide?
If it dies in consequence of injuries received before, during or after birth
What does culpable homicide mean and what does it include?
It means the killng is blameworthy. It includes Murder, manslaugter or infanticide
When is a homicide culpable?
when it consists in the killing of any person by;
-an unlawful act OR
-an Omission without lawful excuse to perform or observe any legal duty OR
-Both combined
-By causing tha person by threats or fear of violence, or by deception, to do an act which causes his death OR
-Wilfully frightening a child under the age of 16 years or a sick person.
Define an unlawful act
Breach of any act, regulation, rule or bylaw
R v Myatt
Before a breach of any act, regulation or bylaw would be an unlawful act under section 160 for the purposes of culpable homicide, it must be an act likely to do harm to the deceased or to some class of persons of whom he was one.
What is an example of an unlawful act that would not constitute as culpable homicide?
Breach of an electoral law, because while its a breach it is not an act likely to do harm to the deceased.
what does section 150A apply to?
any case where the unlawful act requires proof of negligence, or is strict or absolute liability offence
What are some examples of where, someone can be held criminally responsible because there actions were a major departure from the standard of care expected from a reasonable person in the particular circumstances
Where the offender;
-committing arson
-conducting an illegal abortion where the mother dies
-supplying heroin where the person subsequently dies from an overdose
-giving a child an excessive amount of alcohol to drink
What are some examples of common law duties that have been imposed by statute?
*provide the necessaries and protect from injury (s151)
* provide necessaries and protect from injury to your charges when you are
a parent or guardian (s152)
* provide necessaries as an employer (s153)
* use reasonable knowledge and skill when performing dangerous acts,
such as surgery (s155)
* take precautions when in charge of dangerous things, such as machinery
(s156)
* avoid omissions that will endanger life (s157).
What is an example of an unlawful act and an omission of duty at the same time?
to drive a car so recklessly that you kill
a pedestrian is both an unlawful act and an omission to observe your duty to
take precautions when you are in charge of a dangerous thing (s156).
R v Tomars
formulates the issues in the following way:
1. Was the deceased threatened by, in fear of or deceived by the defendant?
2. If they were, did such threats, fear or deception cause the deceased to do the
act that caused their death?
3. Was the act a natural consequence of the actions of the defendant, in the
sense that reasonable and responsible people in the defendant’s position at the
time could reasonably have foreseen the consequences?
4. Did these foreseeable actions of the victim contribute in a [significant] way to
his death?
What are some examples of threats, fear or deception that resulted in homicide?
- jumps or falls out of a window and dies because they think they are
going to be assaulted - jumps into a river to escape an attack and drowns
- who has been assaulted and believes their life is in danger, jumps from a
train and is killed.
What was identified in R v Corbett in relation to threats, fear of violence and deception?
“the victim’s conduct must be such
that it could be reasonably foreseen, is proportionate to the threat, or is
“within the ambit of reasonableness. Although the victim might do the
wrong thing or act unwisely, it is sufficient if the reaction is “in the
foreseeable range.”
What is willfully frightening?
“intending to frighten, or at least be
reckless as to this”
In relation to frightening a child or sick person does it need to be a result of a fear of violence?
No, may be caused by any act that frightens the child or sick
person, so long as it is done willfully
In relation to frightening a child or sick person, what does simester brookbanks say?
“wilfully” would require that the offender
intended to frighten, or is at least subjectively reckless as to the risk of that.
Mens rea should be interpreted as applying to all the elements in s160(2)(e),
so that the defendant must at least have been aware of a real risk that the
victim is under 16 or sick.
What is an example of killing by influence on the mind
A man took tests at a hospital for an ongoing stomach complaint. “For a
joke”, a hospital employee sent him a letter saying he had terminal,
inoperable cancer. If the man had, as a consequence, committed suicide, the
sender of the letter could be charged under s163.
What is section 163? (Influence of the mind)
No one is criminally responsible for the killing of another by any influence on the mind
alone, except by wilfully frightening a child under the age of 16 years or a sick person, nor
for the killing of another by any disorder or disease arising from such influence, except by
wilfully frightening any such child as aforesaid or a sick person.
Can someone consent to being killed?
No one has the right to consent to being killed (s63). This means that, if
someone is killed, the fact they gave their consent will not affect the criminal
responsibility of anyone else involved with the killing.
How do you prove death?
To establish the death, you must prove the:
* death occurred
* deceased is identified as the person who has been killed
* the killing is culpable
Death can be proved by direct and/or circumstantial evidence.
What can you be charged with if someone gets killed in a lawful game or contest?
the death of a participant from injuries received during the
game or contest is normally treated as non-culpable homicide. However, if a
contestant causes the death of another by an act that is likely to cause serious
injury, they will be guilty of manslaughter.
R V Horry
Death should be provable by such circumstances as render it morally certain and
leave no ground for reasonable doubt – that the circumstantial evidence should
be so cogent and compelling as to convince a jury that upon no rational
hypothesis other than murder can the facts be accounted for.
What are some examples of ‘justified’ or non culpable homicides that the perpetrator would be exempt from both criminal and civil liability?
- homicide committed in self-defence (s48)
- homicide committed to prevent suicide or commission of an offence
which would be likely to cause immediate and serious injury to the
person or property of any-one (s41)
If someone is assaulted and they go on life support what happens to the offender?
A defendant will not be relieved of responsibility merely because a life
support system is withdrawn in good faith.
What are the three main types of culpable homicide?
murder, manslaughter and
infanticide.
Is a body required to prove death of a person?
No a body is not required to prove death of a person has occurred. Death should be provable
by such circumstances as render it morally certain and leave no ground for reasonable doubt
– that the circumstantial evidence should be so cogent and compelling as to convince a jury
that upon no rational hypothesis other than murder can the facts be accounted for. R v Horry
What must you show if you are charging an offender with murder?
the defendant:
* intended to cause death, or
* knew that death was likely to ensue, or
* was reckless that death would ensue.
If such intent is not present the offence is manslaughter unless it falls within
the provisions of infanticide (section 178).
What is intent?
A deliberate act to get a prescribed result
R v Cameron
Recklessness is established if:
(a) the defendant recognised that there was a real possibility
that:
(i) his or her actions would bring about the proscribed
result; and/or
(ii) that the proscribed circumstances existed; and
(b) having regard to that risk those actions were unreasonable.
Define recklessness
consciously and deliberately taking an
unjustifiable risk.
R v Piri
Recklessness [here] involves a conscious, deliberate risk taking. The degree of
risk of death foreseen by the accused under either s167(b) or (d) must be more
than negligible or remote. The accused must recognise a “real or substantial risk”
that death would be caused:
Under 167(b) what do you need to establish to show the defendants state of mind?
The defendant;
* intended to cause bodily injury to the deceased
* knew the injury was likely to cause death
* was reckless as to whether death ensued or not
R v Tipple
The Court suggested as a general rule “recklessness” is to be
given the subjective meaning. The concept is subjective in that it requires
that the offender know of, or have a conscious appreciation of the relevant
risk, and it may be said that it requires “a deliberate decision to run the risk”.
R v Desmond
Not only must the object be unlawful, but also the accused must know that his act
is likely to cause death. It must be shown that his knowledge accompanied the
act causing death.
when killing is done in pursuit of an unlawful object what must the Courts consider?
- whether the defendant knew the acts were likely to cause death, and
- whether the defendant’s original intent (e.g. indecent assault) amounted to
an unlawful object.
define parties
Where 2 or more persons form a common intention to prosecute any unlawful
purpose, and to assist each other therein, each of them is a party to every offence
committed by any one of them in the prosecution of the common purpose if the
commission of that offence was known to be a probable consequence of the
prosecution of the common purpose.
What are the three further definitions of murder under section 168
Culpable homicide is also murder in each of the following cases, whether the
offender means or does not mean death to ensue, or knows or does not know that
death is likely to ensue:
(a) If he means to cause grievous bodily injury for the purpose of facilitating the
commission of any of the offences mentioned in subsection (2) of this section,
or facilitating the flight or avoiding the detection of the offender upon the
commission or attempted commission thereof, or for the purpose of resisting
lawful apprehension in respect of any offence whatsoever, and death ensues
from such injury:
(b) If he administers any stupefying or overpowering thing for any of the purposes
aforesaid, and death ensues from the effects thereof:
(c) If he by any means wilfully stops the breath of any person for any of the
purposes aforesaid, and death ensues from such stopping of breath
When committing a crime with another person and the other person kills someone, to be held responsible for it what are the requirements?
it is
not necessary to show that the secondary party knew the death was a
probable consequence of their carrying out the primary purpose. Rather it
must be shown that the secondary party knew it was a probable consequence
that the principal might do an act that would, if death ensued, bring their
conduct within the terms of section 168
What is the punishment for murder?
172 Punishment of murder
(1) Every one who commits murder is liable to imprisonment for life.
(2) Subsection (1) is subject to section 102 of the Sentencing Act 2002
What is section 102 of the sentencing act?
102 Presumption in favour of life imprisonment for murder
(1) An offender who is convicted of murder must be sentenced to imprisonment for life
unless, given the circumstances of the offence and the offender, a sentence of
imprisonment for life would be manifestly unjust.
(2) If a court does not impose a sentence of imprisonment for life on an offender
convicted of murder, it must give written reasons for not doing so.
What are the three elements of an attempted offence?
Intent (mens Rea) to commit an offence
Act (Actus reus) that they did, or omitted to do, something to achieve that end
Proximity, that their act or omission was sufficiently close
It also must be legally possible to commit the offence in the circumstances. A person. Can be convicted if the offence was physically impossible to commit
R v Murphy
When proving an attempt to commit an offence it must be shown that the
accused’s intention was to commit the substantive offence. For example, in a
case of attempted murder it is necessary for the Crown to establish an actual
intent to kill:
Define sufficiently proximate
Generally, to prove an attempt the defendant must have done or omitted to
do some act(s) that is/are sufficiently proximate (close) to the full offence.
Effectively, the defendant must have started to commit the full offence and
have gone beyond the phase of mere preparation – this is the “all but” rule
R v Harpur
[The Court may] have regard to the conduct viewed cumulatively up to the point
when the conduct in question stops … the defendant’s conduct [may] be
considered in its entirety. Considering how much remains to be done … is always
relevant, though not determinative.
What is the test for proximity
- Has the offender done anything more than getting himself into a position
from which he could embark on an actual attempt? or - Has the offender actually commenced execution; that is to say, has he
taken a step in the actual offence itself?
Who decides if the defendant is sufficiently proximate to the full offence?
The Judge because it is a question of law
What is the punishment for attempted murder
Every one who attempts to commit murder is liable to imprisonment for a term not
exceeding 14 years.
When does section 174, counselling or attempting to procure murder, apply?
Section 174 applies where murder is not in fact committed. If the person
incited or counselled commits murder, the parties’ provisions of s 66(1)(d)
will apply to the inciter or counsellor.
Where murder is attempted but not in fact committed, an inciter, counsellor
or procurer will be liable as a party under s 66(1)(d) to an attempt to murder
under s 173.
What are the ingredients for conspiracy to murder?
Every one is liable to imprisonment for a term not exceeding 10 years who;
-conspires
or agrees with any person
-to murder any other person,
-whether the murder is to take
place in New Zealand or elsewhere.
What are the ingredients for Counselling or attempting to Procure murder
Every one is liable to imprisonment for a term not exceeding 10 years who;
-incites,
-counsels,
or attempts to procure any person to murder any other person in New Zealand,
-when that murder is not in fact committed.
R v Mane
For a person to be an accessory the offence must be complete at the time of the
criminal involvement. One cannot be convicted of being an accessory after the
fact of murder when the actus reus of the alleged criminal conduct was wholly
completed before the offence of homicide was completed.
What is the penalty for Accessory after the fact to murder?
Every one is liable to imprisonment for a term not exceeding 7 years who is an accessory
after the fact to murder.
What are the two types of manslaughter?
- voluntary manslaughter
- involuntary manslaughter
If you make a suicide pact with someone, what would the charge be if you don’t get to kill yourself but the other person does
Manlaughter (Voluntary)
What does involuntary manslaughter cover?
Types of unlawful killing in which the death is caused by an
unlawful act or gross negligence.
What does manslaughter include?
Manslaughter, then, includes culpable homicide that:
* does not come within s167 or s168
* comes within ss167 and 168, but is reduced to manslaughter because the
killing was a part of a suicide pact as defined in s180(3) of the Crimes
Act 1961.
What are some instances where a manslaughter charge might arise?
-Killing in a sudden fight
-By unlawful act
-By negligence
what is the four point test for proving an unlawful act for manslaughter?
- The defendant must intentionally do an act
- The act must be unlawful
- The act must be dangerous
- The act must cause death
In manslaughter by negligence what do you need to consider?
Remember that in many instances the defendant will have been engaged in a
dangerous act or in charge of a dangerous thing, so you need to follow the
standards set out in s155 and 156 to establish what, if any, negligence there
has been.
What are some examples of where manslaughter by negligence may arise?
negligence while in charge of or using trains, factory
machinery, mines, motor vehicles, ships or weapons, or while administering
medical or surgical treatment.
What are three scenario examples of manslaughter
-using a dangerous thing riskily or negligently with the consent of the person who died, still manslaughter
-Someone dies in a game or lawful contest and the defendants actions were likely to cause serious injury
-Contributory negligence, being negligent with someone else and they die, still manslaughter
What is the major departure test?
The ‘major departure’ test in s 150A(2) requires a high degree of negligence,
corresponding to the common law standard of gross negligence,
if a person is to be criminally responsible under s 160(2)(b) for manslaughter by
negligent omission to perform or observe any of the legal duties specified in
s 150A(1)(a) or under s 160(2)(a) for manslaughter by an unlawful act
requiring proof of negligence or imposing strict or absolute liability.
What type of test is it when determining whether a defendant was negligent and whether the negligence was a major departure?
An objective test, and that the defendant’s state of
mind is not a prerequisite to conviction for manslaughter by gross
negligence. All the circumstances of the case must be considered and a
defendant’s state of mind may be relevant to whether there was gross
negligence. This may be more readily found if, for example, the defendant
knowingly ran a risk or was indifferent to an obvious risk of death.
What is the punishment for manslaughter?
177 Punishment of manslaughter
(1) Every one who commits manslaughter is liable to imprisonment for life
If and offender intends to kill A but inadvertently strikes the fatal blow to B, is the offender still guilty of murder?
In a case where an offender intends to kill A but inadvertently strikes and kills B, the guilt of
the offender is not affected. Section 167(c) states that if the offender means to cause the
death of one person and by mistake or accident kills another, even though he did not mean to
hurt the other person, then it is murder.
What does the Crown needs to prove with a charge of attempted muder?
When a charge of attempt to murder is made, the Crown must establish the mens rea and
actus rea as set out in s72 of the Crimes Act 1961. An intention to kill must be proved.
Define voluntary manslaughter and involuntary manslaughter
. In voluntary manslaughter, mitigating circumstances (such as a suicide pact) reduce what
would otherwise be murder to manslaughter, even though the defendant may have intended
to kill or cause grievous bodily harm. Involuntary manslaughter covers those types of
unlawful killing in which death is caused by criminal negligence. In such cases there has
been no intention to kill or cause grievous bodily harm.
When deciding what charges to lay where someone has been killed in a sudden fight, what issues should you consider?
− self-defence
− the requisite mens rea for a murder/manslaughter charge.
What is infanticide?
-Where a woman causes the death of any child of hers under the age of 10 years
-in a manner that amounts to culpable homicide, and where at the time of the offence the
balance of her mind was disturbed,
-by reason of her not having fully recovered from the effect of giving birth to that or any other child,
-or by reason of the effect of lactation
-or by reason of any disorder consequent upon childbirth or lactation, to
such an extent that she should not be held fully responsible,
-she is guilty of infanticide, and not of murder or manslaughter, and is liable to imprisonment for a
term not exceeding 3 year
In cases of infanticide, what must you establish?
In cases of infanticide, the killing of the child must be in a manner that
would amount to culpable homicide. As well as establishing that fact, you
must prove the mother’s mind was disturbed as a consequence of the birth of
that child or of another child. The term “as a consequence” includes the
period of lactation
