Abduraghman Thebus and Moegamat Adams v The State

On 14 November 1998, a group of protesting residents in Ocean View, Cape Town, gathered and approached houses of reputed drug dealers. As the group's motorcade moved through the area, a drug dealer named Grant Cronje opened fire on the group. Some members of the group returned fire. In the resulting crossfire, a seven-year-old girl, Crystal Abrahams, was fatally shot and two others were wounded. The two appellants were arrested on suspicion of being part of the group involved in the shooting. After arrest, the first appellant was warned of his right to remain silent but made an oral statement to police saying "the family was in Hanover Park" but refused to make a written statement. Nearly two years later at trial, both appellants disclosed alibi defences for the first time. A state witness, Gregory Edward Kiel, testified that he saw the first appellant holding a pick-handle and the second appellant retrieving spent cartridges. The trial court rejected the alibi defences and convicted both appellants of one count of murder and two counts of attempted murder based on the doctrine of common purpose. The Supreme Court of Appeal confirmed the convictions and increased the sentences from 8 years suspended to 15 years imprisonment. The SCA drew an adverse inference from the first appellant's failure to disclose his alibi before trial.

• Whether the common law doctrine of common purpose is consistent with the Constitution, particularly the rights to dignity, freedom and security of the person, and the right to be presumed innocent
• Whether the SCA failed to develop the common law doctrine of common purpose in accordance with section 39(2) of the Constitution
• Whether drawing a negative inference from the first appellant's failure to disclose an alibi defence prior to trial violated his constitutional right to silence under section 35(1)(a) of the Constitution
• Whether the requirement of a causal connection between the accused's actions and the criminal result should be required under common purpose
• Whether the requirement of active association under common purpose was properly applied
• Whether subjective fault must be proved for each accused in a common purpose case

The appeals of both the first and second appellants were dismissed. The convictions for one count of murder and two counts of attempted murder were upheld, as were the sentences of 15 years imprisonment imposed by the Supreme Court of Appeal.

The binding legal principles established are: (1) The common law doctrine of common purpose, as formulated in S v Mgedezi and subsequent cases, is constitutionally valid and does not require a causal connection between the conduct of each participant and the criminal result. (2) For common purpose liability where the accused is present at the scene, the state must prove beyond reasonable doubt: (a) presence at the scene; (b) awareness of the assault or criminal conduct; (c) intention to make common cause with the perpetrators; (d) active association with the conduct of others through some act; and (e) the requisite mens rea (intention or dolus eventualis regarding the criminal result). (3) An inference of guilt cannot be drawn from an accused's pre-trial silence alone, as this would violate the right to silence and the presumption of innocence. (4) The appropriate approach to alleged violations of the right to silence must be assessed in the context of ensuring a fair trial under section 35(3) of the Constitution. (5) Where an accused makes a statement after being warned of the right to silence, inconsistencies between that statement and later testimony may be used in cross-examination and in evaluating credibility. (6) In determining guilt, a court must consider the totality of all admissible evidence on a conspectus, regardless of its source.

Several important obiter observations were made: (1) Moseneke J observed that if legislation were enacted requiring timeous disclosure of alibi defences with appropriate warnings, it would likely constitute a justifiable limitation of the right to silence under section 36 of the Constitution. (2) The judgment noted that the South African Law Commission has recommended legislation permitting adverse inferences from failure to disclose alibis in certain circumstances. (3) Goldstone J and O'Regan J observed that rules similar to common purpose exist in many common law jurisdictions but not in civil law systems like France and Germany. (4) The Court noted that while common purpose is frequently applied in murder cases, it also applies to various other crimes including treason, public violence, robbery, and assault, though the Court declined to express a view on its application to culpable homicide. (5) The judgment emphasized that superior courts have always had inherent power to develop the common law, now constitutionally authorized and mandated to promote the values in the Bill of Rights. (6) Yacoob J observed that the distinction between inferences as to guilt and inferences as to credibility may be over-theoretical and that courts should focus on substantive fairness rather than rigid categorical distinctions. (7) The judgments collectively emphasized that the right to a fair trial encompasses substantive fairness, not merely procedural fairness, and requires balancing the rights of the accused, victims, and society's interest in effective law enforcement.

This is a leading Constitutional Court judgment on two critical issues in South African criminal law: (1) It comprehensively confirmed the constitutional validity of the common law doctrine of common purpose, holding that it does not require a causal connection between each participant's conduct and the criminal result, and that it serves legitimate crime control purposes without unjustifiably limiting constitutional rights. (2) It provided detailed guidance on the right to silence under section 35(1)(a) of the Constitution, particularly regarding the disclosure of alibi defences. The judgment established that while an inference of guilt cannot be drawn from pre-trial silence alone, the matter is more complex regarding credibility inferences and cross-examination. The different approaches in the various judgments reflect ongoing tensions in balancing the rights of accused persons against effective law enforcement. The case demonstrates the Court's approach to developing common law under section 39(2) of the Constitution and the requirement that all aspects of criminal trials must conform to the right to a fair trial under section 35(3). It remains an important authority on common purpose liability and the right to silence in South African constitutional criminal procedure.
