LO1: Define a perpetrator in the commission of a crime and differentiate between different types of perpetrators |
A person is a PERPETRATOR if |
a) his conduct, the circumstances in which it takes place and the culpability with which it is carried out are such that he satisfies all the requirements for liability; |
b) if he acted together with one or more persons and the conduct required for a conviction is imputed to him by virtue of the principles relating to common purpose. |
The different persons who may be involved in the commission of a crime are divided into 3 categories: perpetrators, accomplices & accessories after the fact. |
ACCOMPLICE |
Somebody who does not satisfy all the requirements for liability contained in the definition of the crime; |
does not qualify for liability ito the principles relating to common purpose BUT who unlawfully and intentionally furthers its commission by somebody else. |
Consciously associates themselves with the commission of a crime by assisting the perpetrator/co-perpetrators, giving them information/advice OR offering them the opportunity or means to commit the crime or facilitate its commission. |
ACCESSORY AFTER THE FACT |
a) somebody who, after the commission of the crime, unlawfully and intentionally helps the perpetrator or accomplice to escape liability. |
b) only comes in AFTER the commission of the crime |
CO-PERPETRATORS |
If several persons commit a crime together, it is unnecessary to single out who can be the perpetrator and that helpers, must necessarily fall into a different category. |
1) not always practical to identify one principle perpetrator as the principle offender or actual perpetrator |
2) if several people commit a crime and all comply with all the requirements for perpetrators, they are simply co-perpetrators |
3) two persons may act in such a way that each contributes equally to the crime |
DIRECT & INDIRECT PERPETRATORS |
a) An indirect perpetrator is somebody who commits a crime through the instrumentality of another. b) the distinction that may be drawn between direct & indirect perpetrators is irrelevant. c) direct/indirect perpetrators are suitable terms to describe a factual situation. d) the difference between the two has no bearing on a person's liability |
LIABILITY OF PERPETRATOR NOT ACCESSORY IN NATURE |
a) liability of a perpetrator/co-perpetrator is based on his own act and his own culpability. |
b) DOES NOT depend on the commission of a crime by somebody else; his liability is completely independent |
LO 2: Explain the need for and the role of the doctrine of common purpose |
NECESSITY OF DOCTRINE OF COMMON PURPOSE |
1) If several people acting together killed 'Y', it is always impossible to ascertain with certainty who amongst them contributed casually to 'Y's' death |
2) It may be without a doubt that at least one of the group, namely the shooter, caused Y's death but there are also situations in which the conduct of no single one of them can with certainty be described as a cause of Y's death. |
LO3: Define the doctrine of common purpose |
THE DOCTRINE OF COMMON PURPOSE: SUMMARY OF PRINCIPLES |
Courts apply a scientific doctrine to enable it to convict several people acting together of murder - doctrine of common purpose |
1) If 2 or more people, having a common purpose to commit a crime, act together in order to achieve that purpose, the conduct of each of them in the execution of that purpose is imputed to the others. |
2) In a charge of having committed a crime which involves the causing of a certain result, the conduct imputed includes the causing of such result |
3) Conduct by a member of the group of persons having a common purpose which different from the conduct envisaged in the said common purpose may not be imputed to another member of the group unless the latter knew that such other conduct would be committed, or foresaw the possibility that it might be committed & reconciled himself to that possibility. |
4) A finding that a person acted together with one or more other persons in a common purpose is not dependent upon proof of a prior conspiracy. Such a finding may be inferred from the conduct of a person or persons. |
5) A finding that a person acted together with one or more other persons in a common purpose may be based upon the first-mentioned person's active association in the execution of the particular criminal act of the other participant(s). HOWEVER, in a charge of murder this rule applies only if the active association took place while the deceased was still alive and before a mortal wound or mortal wounds had been inflicted by the person or persons with whose conduct such first-mentioned person associated himself. |
6) If, on a charge of culpable homicide the evidence reveals that a number of persons acted with a common purpose to assault or commit robbery and that the conduct of one or more of them resulted in the death of the victim, the causing of the victim's death is imputed to the other members of the group as well, but negligence in respect of the causing of the death is not imputed. |
THE DOCTRINE OF COMMON PURPOSE - GENERAL |
- If 2 or more people in acting in common purpose to commit a crime, the conduct of each of them in the execution of that purpose is imputed to the others. |
- Common purpose is not couched in general terms and therefore, not confined to one type of crime only. mostly found within the context of the crime of murder |
- The persons must all have had the intention to murder and to assist one another in committing the murder. |
- The basis of the doctrine is the idea that each member of that plot gave the other an implied mandate to execute the unlawful criminal act. |
DIFFERENCE BETWEEN PRIOR CONSPIRACY & ACTIVE ASSOCIATION |
Restrictions to common purpose doctrine |
~ If reliance is placed on a prior agreement or conspiracy between the participants, it is enough to prove that X agreed with the wide and general common design of conspirators. |
~ If reliance is placed not on a previous conspiracy, but on active association, there must be proof that X associated himself, not with the wide and general common design, but with the specific act, whereby the other participants committed the crime. |
COMMON PURPOSE AND DOLUS EVENTUALIS |
For X to have a common purpose with others to commit murder, it is not necessary that his intention to kill be present in the form of dolus directus |
It is enough if his intention takes the form of dolus eventualis |
COMMON PURPOSE IN CHARGES OF CULPABLE HOMICIDE |
1. One cannot intend to be negligent |
2. An inference can be drawn that the common purpose doctrine can never be applied to convict people of culpable homicide |
3. If there are difficulties in proving causation, the doctrine can be applied in charges of culpable homicide, see decision in Nkwenja, Magmoed v Janse van Rensburg, read with Sefatsa |
LO5: Evaluate the constitutionality of the doctrine of common purpose with reference to applicable case law |
COMMON PURPOSE DOCTRINE IS CONSTITUTIONAL |
In Thebus, the ConCourt held that the doctrine is compatible with the Constitution. |
~ X's rights to dignity & freedom aren't infringed |
~ If the doctrine didn't exist, |
1) there would have been acceptable situations convicting only the person who had actually committed the principle act |
2) whereas those who have intentionally contributed to the commission of the crime would have been guilty. |
LO4: Identify the requirements of an effective withdrawal from a common purpose |
1) To escape conviction on the ground of a withdrawal from the common purpose, X must have clear intention to withdraw from such a purpose; |
2) To succeed with the defence of withdrawal, X must perform some positive act of withdrawal; |
3) The withdrawal must be voluntary, if X withdraws upon discovering that the police had uncovered the plot, the withdrawal is not voluntary; |
4) The withdrawal will amount to a defence only if it takes place before the course of events start taking place; |
5) The type of act required for an effective withdrawal depends upon a number of circumstances |
6) The role played by X in planning to commit the crime has a strong influence on the type of conduct which the law requires him to perform t succeed with a defence of withdrawal |
ACTIVE ASSOCIATION IN COMMON PURPOSE |
It follows that prior agreement is not the only form of common purpose liability. |
2 categories of common purpose |
1) where there is prior agreement to commit a common offence; |
2) where liability arises from an active association and participation in a common criminal design with the requisite intention to commit a crime |
If there is no proof of prior agreement, the following 5 REQUIREMENTS must be met according to the decision in Mgedezi |
1) X must have been present at the scene of the crime; |
2) X must have been aware of the assault on Y; |
3) X must have intended to make common cause with the person or persons committing the assault; |
4) X must have manifested his sharing of a common purpose by himself performing some act of association with the conduct of others; |
5) X must have intended to kill Y |
