Criminal law functions as society’s method of social control: it sets
boundaries both to our behaviour and to the power of the state to
coerce and punish us.
Criminal law ensures that human-beings treat each other as human-
beings, rather than as objects.
THE AMERICAN PENAL CODE:
The American Model Penal Code provides us with a statement of the
proper purposes of criminal law:
A. To forbid and prevent conduct that unjustifiably and inexcusably
inflicts/ threatens substantial harm to individuals/ public interests.
B. To subject people whose conduct indicates that they are disposed to
commit crimes to public control.
C. To safeguard conduct that is without fault from being condemned as
criminal.
D. To give fair warning of the nature of offensive conduct.
E. To differentiate between serious and minor offences on reasonable
grounds.
2. PRINCIPLES OF CRIMINALISATION:
PRINCIPLE OF LEGALITY: this principle is a matter of general legislative
morality. It requires that fair warning be given regarding the kind of
conduct that is criminalised, or else the lawfulness of prohibiting
that conduct will be compromised. Further, it discourages the state’s
use of criminal law for political ends, rather than social ends. There are
two limbs to this:
Firstly, criminal laws should not be retroactive (backdated),
especially in modern liberal democracies.
Secondly, offence definitions should not be unduly vague.
Citizens need to be given fair warning of the criminality of certain
actions and in order for such warning to be given, they should not be
left unsure of whether the relevant conduct was prohibited or not.
! Also note the thin-ice principle by Ashworth and Horder in relation to fair
warnings: those who skate at the margins of legality cannot complain if they are not
given precise warning as to when they are about to fall in.

REVISION NOTES
PRINCIPLE OF RESPONSIBILITY: unless the relevant conduct consists of a
moral fault, a person should not be blamed and suffer punishment, however
serious the consequences of their conduct.
PRINCIPLE OF URGENCY/ MINIMAL CRIMINALISATION: criminal
consequences of conduct that consists of a moral fault should only be
attended to if there are substantial interferences with/ threats to public
interest.
PRINCIPLE OF PROPORTIONALITY: the severity of a sentence should vary
according to the seriousness of an offence.
PRINCIPLE OF FAIR LABELLING: the moral distinctions between different
kinds f conduct should be reflected by the creation of different offences.
3. IMPORTANCE OF PUBLIC AND PRIVATE INTERESTS:
PUBLIC INTERESTS:
Preventing physical injury (through crimes of violence, such as murder and
arson).
Proscribing personal immorality deemed injurious to society’s well-
being (through criminalising incest, drug possession, bestiality,
sadomasochism, etc.).
Preventing the moral corruption of the youth (through crimes such as
unlawful sexual intercourse).
Maintaining the integrity of the state and the administration of
justice (through crimes such as perverting the course of justice, tax evasion,
etc.).
Maintaining public order and security (through offences such as public
drunkenness, riot, etc.).
PRIVATE INTERESTS:
Remaining free from:
Undesired physical interference (through crimes such as rape and
assault).
Offence (through crimes such as indecent exposure, indecency in public,
etc.).
Undesired interference with property (through crimes such as theft and
robbery).
4. PRINCIPLES/ IDEAS INFORMING DECISIONS TO CRIMINALISE:
1. AUTONOMY:
Human action is seen as the product of free, rational choices on the part of
the individual (HJ Paton). Therefore, humans are their own autonomous
