A Farquharson direction is a jury instruction that courts give when the prosecution's case rests entirely, or substantially, on circumstantial evidence. The direction tells jurors the specific reasoning path they must follow before they can return a guilty verdict: every fact they rely on to reach that conclusion must itself be proved beyond reasonable doubt, and the combination of those facts must be inconsistent with any reasonable hypothesis of innocence. It's a structured safeguard, not a formality.
Where the name comes from
The direction takes its name from the Victorian case Farquharson v The Queen [2009] VSCA 307, in which Robert Farquharson was convicted of murdering his three sons by driving a car into a dam on Father's Day 2005. The prosecution's case was built entirely on circumstantial evidence. The Victorian Court of Appeal used the case to clarify the correct direction that trial judges must give to juries in circumstantial cases, cementing principles that had developed across earlier authorities into a clearer, more workable formula.
The Supreme Court of Victoria has since applied and refined the direction in a number of contested trials. Courts in New South Wales and other states draw on the same underlying principles, even if they don't always use the Farquharson label.
The core test the direction sets out
When a judge gives a Farquharson direction, the jury receives the following framework:
- Each fact relied on as a step toward guilt must be proved beyond reasonable doubt on its own.
- Once those facts are established, the jury asks whether the only rational inference from the combination of those facts is that the accused is guilty.
- If a reasonable hypothesis consistent with innocence can be drawn from the proven facts, the jury must acquit.
This is distinct from a direct evidence case, where a witness saw the accused commit the act or the accused admitted to it. Circumstantial cases require the jury to reason by inference, and the Farquharson direction keeps that reasoning within strict logical bounds.
Why it matters to the accused
The direction is one of the most important protections a defendant has when the prosecution relies on inference rather than direct observation. Without it, jurors might treat accumulated suspicion as proof. With it, the jury is required to test every step in the chain of reasoning. A single link that cannot be proved beyond reasonable doubt can be enough to collapse the prosecution's case.
Failure to give a correct Farquharson direction, or giving a defective version of it, is a recognised ground of appeal. In the Farquharson case itself, the original conviction was set aside partly because of errors in the directions given to the jury. Farquharson was retried, convicted again, and that conviction was ultimately upheld. But the case illustrates clearly that an error in how the jury is instructed on circumstantial reasoning is taken seriously at the appellate level.
If you're facing a committal hearing in a matter where the prosecution's evidence is largely circumstantial, the question of what directions the trial judge will ultimately give is already relevant to how your defence should be framed.
How it differs from the standard reasonable doubt direction
Every criminal trial requires the jury to be told that the prosecution must prove guilt beyond reasonable doubt. The Farquharson direction adds a layer on top of that. It doesn't replace the reasonable doubt standard. It tells the jury how to apply that standard when the evidence is indirect.
Think of it this way. In a direct evidence case, the juror asks: do I believe this witness beyond reasonable doubt? In a circumstantial case, the juror must ask something more complex: do I accept each individual fact that the prosecution relies on, and does the combination of those accepted facts exclude every other rational explanation? The Farquharson direction makes that two-step structure explicit.
Circumstantial evidence in practice
Circumstantial cases appear across a wide range of charge types. Murder, fraud, arson, and drug trafficking prosecutions frequently turn on inference rather than eyewitness accounts. Forensic evidence, financial records, phone data, CCTV footage, and expert testimony can all be circumstantial. Each item points toward a conclusion without directly proving it.
In a voir dire, contested circumstantial evidence can sometimes be excluded before it even reaches the jury. Where evidence survives that threshold, the Farquharson direction becomes the critical tool that shapes how the jury engages with it.
What defence lawyers focus on in circumstantial cases
Experienced criminal law practitioners analyse circumstantial cases in two stages. First, they scrutinise each individual piece of evidence to identify any that can be contested, excluded, or undermined. Second, they work at the level of inference: even if the jury accepts all the prosecution's facts, does the combination of those facts really exclude every rational alternative?
