Many people believe that criminal prosecutions require direct evidence, such as evidence from an eyewitness or some form of physical proof. The reality is that a significant number of criminal cases rely heavily or entirely on what is called ‘circumstantial evidence’.
Circumstantial evidence can be powerful, but it also carries inherent risks of misinterpretation and incorrect assumptions; risks that an experienced defence lawyer can quickly identify.
What is circumstantial evidence
Circumstantial evidence is evidence of facts or circumstances from which other facts may be inferred.
Rather than directly proving a particular fact, circumstantial evidence requires the fact finder (this may be a judge or a jury) to find certain basic facts and then, from those facts, draw a conclusion as to the existence of a further fact. The fact finder will consider all of those facts together as a whole and consider whether it can be concluded from those facts that the accused is guilty beyond reasonable doubt.
Common examples of circumstantial evidence
Modern criminal cases frequently rely on various types of circumstantial evidence that prosecutors use to build their case, such as:
- CCTV footage showing someone in an area where a crime occurred
- Mobile phone location data, placing a device near a crime scene
- Financial records showing unusual transactions or spending patterns
- DNA evidence found at a scene without direct proof of how it got there
- Internet search history or communications suggesting planning or motive
- Witness evidence about behaviour before or after an alleged offence
The prosecution then seeks to use these individual facts to draw an inference that a person committed the crime.
While each piece might not seem compelling in isolation, the strength of circumstantial evidence depends on how well these pieces connect and whether they exclude other reasonable hypotheses.
Challenging circumstantial evidence
Challenging circumstantial evidence involves exposing gaps in the chain of reasoning and demonstrating alternative explanations based on the evidence, consistent with innocence.
An effective defence will identify weaknesses in how circumstances are relied upon by the prosecution, highlight missing links in the prosecution narrative, and present alternative theories that explain the evidence.
Where the prosecution case rests substantially on circumstantial evidence, a jury cannot return a guilty verdict unless the prosecution has excluded all reasonable hypotheses consistent with innocence. If the defence can show that other reasonable explanations exist, the high standard of proof beyond reasonable doubt has not been met.
When juries are warned about circumstantial cases
In jury trials involving circumstantial evidence, judges must give specific warnings to the jury about the way in which they may reason and draw inferences from circumstantial evidence. Juries are instructed that before convicting a person, they must consider the evidence and be satisfied that the inferences the prosecution asks them to draw from the circumstances are the only reasonable inferences that may be drawn.
This is a powerful protection that requires juries to consider whether alternative explanations exist before concluding that the guilt of the accused is the only reasonable inference.
