Principles of Criminal Law Fully Solved Assignment with Verified Answers
| Criminal Liability, Elements of Crime, Intention and Negligence,
Defences, Criminal Procedure Basics and South African Criminal Law
Principles
Question 1: In South African criminal law, which of the following represents the
correct sequential order for determining criminal liability?
A. Unlawfulness, Act, Definitional elements, Culpability
B. Act, Definitional elements, Unlawfulness, Culpability
C. Culpability, Unlawfulness, Act, Definitional elements
D. Definitional elements, Act, Culpability, Unlawfulness
CORRECT ANSWER: B. Act, Definitional elements, Unlawfulness, Culpability
Rationale: Criminal liability in South African law requires a specific analytical sequence:
first, establishing that the accused committed a voluntary act or omission; second,
determining whether that conduct complies with the definitional elements of the
charged crime; third, assessing whether the conduct was unlawful (i.e., not justified);
and finally, evaluating whether the accused was culpable (possessed criminal capacity
and fault in the form of intention or negligence). If any element is absent, liability cannot
be established, making the sequence critical.

Question 2: The principle of legality in South African criminal law is constitutionally
entrenched in which provision?
A. Section 12 of the Constitution
B. Section 33 of the Constitution
C. Section 35(3)(l) of the Constitution
D. Section 39(2) of the Constitution
CORRECT ANSWER: C. Section 35(3)(l) of the Constitution
Rationale: Section 35(3)(l) of the Constitution of the Republic of South Africa, 1996,
expressly provides that every accused person has the right not to be convicted of a
crime unless the conduct was recognised by law as a crime, in clear terms, before the
conduct occurred, and without requiring broad interpretation of the definition. This
provision embodies the nullum crimen sine lege principle, forming the cornerstone of
the principle of legality in our criminal law.

Question 3: Which Latin maxim expresses the rule that a court may not create a
new crime?
A. Nulla poena sine lege
B. Ius certum
,C. Ius acceptum
D. Ius praevium
CORRECT ANSWER: C. Ius acceptum
Rationale: The ius acceptum rule, derived from the principle of legality, stipulates that
conduct can only be punished as a crime if it was already recognised as such by law
(either common law or statute) at the time of commission. Courts lack legislative
authority to create new crimes; this power resides exclusively with the legislature. This
rule ensures legal certainty and prevents arbitrary criminalisation.

Question 4: In the case of S v Masiya, the Constitutional Court extended the
common-law definition of rape. However, the extended definition was not applied
retrospectively to the accused. Which principle of legality does this illustrate?
A. Ius certum
B. Ius strictum
C. Ius praevium
D. Nulla poena sine lege
CORRECT ANSWER: C. Ius praevium
Rationale: The ius praevium rule prohibits the retrospective creation or extension of
crimes to the detriment of an accused. Although the Constitutional Court in Masiya
extended the definition of rape to include non-consensual anal penetration of a female,
it held that this extension could not apply to conduct occurring before the judgment, as
that would violate the accused's right not to be convicted for conduct not criminal at the
time it was committed.

Question 5: Which requirement of criminal liability refers to the accused's mental
state, encompassing either intention or negligence?
A. Actus reus
B. Unlawfulness
C. Culpability
D. Definitional elements
CORRECT ANSWER: C. Culpability
Rationale: Culpability (or fault) is the fourth requirement for criminal liability and
concerns the accused's blameworthy mental state. It requires that the accused
possessed criminal capacity and acted with either intention (dolus) or negligence
(culpa) regarding the unlawful conduct and its consequences. Without culpability, even
unlawful conduct satisfying definitional elements cannot result in criminal conviction.

,Question 6: Which of the following scenarios would MOST likely constitute a
voluntary act for purposes of actus reus?
A. A person convulses during an epileptic seizure and strikes another
B. A sleepwalker throws an object that injures someone
C. A driver loses consciousness due to a sudden heart attack and causes a collision
D. A person deliberately pushes another during an argument
CORRECT ANSWER: D. A person deliberately pushes another during an argument
Rationale: For conduct to qualify as an "act" in criminal law, it must be voluntary—
willed or controlled by the accused's conscious mind. Options A, B, and C describe
involuntary movements (automatism) arising from medical conditions, which generally
negate the act requirement. Only option D involves conscious, willed muscular
movement, satisfying the voluntariness element of actus reus.

Question 7: In South African criminal law, an omission can only found liability if:
A. The accused intended the harmful consequence
B. There was a legal duty to act positively
C. The omission caused physical harm
D. The accused was aware of the risk
CORRECT ANSWER: B. There was a legal duty to act positively
Rationale: Criminal liability for an omission is exceptional and requires proof of a legal
duty to act positively. Such duties may arise from statute, common law (e.g., parental
duty), contract, voluntary assumption of care, or creation of a dangerous situation.
Without a recognised legal duty, mere failure to act, however morally blameworthy,
does not constitute unlawful conduct for criminal liability.

Question 8: The requirement that the accused's conduct must correspond with the
description of the crime in the relevant definition is known as:
A. Unlawfulness
B. Causation
C. Compliance with definitional elements
D. Criminal capacity
CORRECT ANSWER: C. Compliance with definitional elements
Rationale: After establishing a voluntary act, the second requirement for liability is that
the conduct must comply with the definitional elements (or "type of conduct") of the
specific crime charged. This ensures that only conduct falling within the statutory or
common-law description of an offence can be prosecuted, giving effect to the principle
of legality and legal certainty.

Question 9: Which ground of justification renders conduct lawful because it was
necessary to protect a legally recognised interest from an unlawful attack?
A. Consent
B. Private defence
C. Necessity
D. Official capacity
CORRECT ANSWER: B. Private defence
Rationale: Private defence (self-defence) justifies otherwise unlawful conduct when it is
directed at warding off an unlawful, imminent attack against a legally protected interest
of the defender or another. The defensive act must be necessary, reasonable, and
proportionate. Unlike necessity, private defence specifically responds to a human-
originated unlawful attack.

Question 10: In the context of causation, the "but-for" test is used to determine:
A. Legal causation
B. Factual causation
C. Novus actus interveniens
D. Reasonable foreseeability
CORRECT ANSWER: B. Factual causation
Rationale: Factual causation is established using the conditio sine qua non or "but-for"
test: but for the accused's conduct, would the prohibited consequence have occurred
when and as it did? If the answer is no, factual causation is present. Legal causation, a
separate inquiry, then assesses whether the link is sufficiently close to attribute legal
responsibility, considering factors like reasonable foreseeability and novus actus
interveniens.

Question 11: Which of the following best describes "dolus eventualis" in South
African criminal law?
A. The accused directly intended the prohibited consequence
B. The accused foresaw the possibility of the consequence and reconciled themselves
to it
C. The accused was negligent in not foreseeing the consequence
D. The accused acted under a mistaken belief that their conduct was lawful
CORRECT ANSWER: B. The accused foresaw the possibility of the consequence
and reconciled themselves to it
