, THEME 1: INTRODUCTION
Principle of Legality
And more specifically its practical application when it comes to criminalization
Principle of legality rules:
IUS = law or right
1. IUS ACCEPTUM
- the conduct must be recognized by law as a crime
- Conduct must be declared as a crime by common law sources or the legislature
(parliament)
- the courts don’t have the competency to declare a conduct a crime
-courts are bound by the law as we have received it to date
-if courts had the power to define new crimes, it would infringe on IUS CERTUM and IUS
PRAEVIUM principles since law making is both uncertain and retrospective
2. IUS PRAEVIUM
- Conduct must be recognized as a crime before it took place
- you can’t blame someone for doing a crime if it wasn’t a criminalized at the time – this is
even said in the constitution
- Constitution section 35(3)(1) … “right to a fair trial includes the right not to be convicted
for an act or omission that was not an offence under either national or international law at
time it was committed or omitted
3.IUS CERTUM
- Law must be clear and unambiguous. The law mustn’t be vague
- implies the principle of fair warning
4. IUS STRICTIM
- must interpret crime narrowly
- if there’s doubt about whether someone’s conduct has infringed upon
legislation/prohibition. Crimes must be narrowly interpreted.
5. NULLA POENA SINE LEGE
- No punishment without law
Explain the implication that these rules have for a lawmaker that is undertaking
criminalisation
Criminalisation = decision to prohibit conduct as a crime. Hence, a crime is conduct that the
law has declared to be criminal.
The only body who may criminalise conduct is parliament (the legislature)
