Step 1: Understanding the Question:
The question asks to identify the test that reflects the principle of "factual causation" in criminal law. This requires distinguishing between different legal tests used in criminal jurisprudence.
Step 2: Key Concepts and Approach:
In result crimes (like murder), the prosecution must prove a causal link between the accused's act and the prohibited result. This causal chain has two parts:
• Factual Causation: This establishes a physical link between the act and the result. It is the preliminary, scientific inquiry.
• Legal Causation (or Proximate Cause): This is a legal or policy-based inquiry to determine if the accused's act was a sufficiently direct and substantial cause of the result to justify holding them criminally liable.
We need to identify the test used for the first part, i.e., factual causation.
Step 3: Detailed Explanation:
• (A) The "But For" Test (‘causa sine qua non‘): This is the standard test for factual causation. The question asked is: "But for the accused's conduct, would the result have occurred?" If the answer is "no" (the result would not have occurred), then factual causation is established. For example, 'but for' the accused stabbing the victim, the victim would not have died.
• Evaluating other options:
- (B) Proximity Test: This is a test for legal causation, not factual causation. It is also used to determine when an act of preparation becomes a criminal attempt. It asks how close the accused's act was to the final result.
- (C) Equivocality Test: This is a test for ‘actus reus‘ in criminal attempts. It asks whether the accused's act unequivocally indicates their intention to commit the crime.
- (D) Social Danger Test: This is another test for attempt, focusing on whether the accused's conduct poses a social danger.
Step 4: Final Answer:
The principle of factual causation is reflected in the "but for" test, which asks whether the prohibited result would have occurred without the accused's action.
