What is the rule in Browne v Dunn?
The rule in Browne v Dunn is a rule of fairness in cross-examination: if you intend to later contradict a witness, or to ask the court to disbelieve them, you must first put the substance of that challenge to them while they are still giving evidence — so they have a fair chance to respond or explain.
In short, the rule says you cannot ambush a witness. If you plan to argue that a witness is lying, mistaken, or that the truth is different from what they have said, you have to give that witness the opportunity to deal with your version while they are in the witness box. You do this by "putting" your case to them in cross-examination. If you stay silent, let their evidence pass unchallenged, and then attack it in your closing address, the court may simply refuse to let you make that attack.
The rule takes its name from an 1893 decision of the House of Lords, Browne v Dunn (1893) 6 R 67. It is sometimes written "Brown v Dunn" (without the "e"), but the correct spelling is Browne. The rule applies right across Australia, in both criminal and civil cases, and it has survived the introduction of the uniform Evidence Acts.
It is important to understand what kind of rule this is. The rule in Browne v Dunn is a rule of fairness and professional practice — not a strict, technical rule of evidence. It exists to serve three kinds of fairness at once: fairness to the witness, who should not have their honesty or accuracy attacked behind their back; fairness to the opposing party, who can then decide what other evidence to call to support that witness; and fairness to the court or jury, which should not be misled into thinking a point was uncontested when it was always going to be challenged. Because it is a rule of fairness rather than a rigid rule of law, the courts apply it flexibly — and, as you will see below, breaking it does not automatically decide the case.
A simple example
The rule is easiest to understand through an example.
Worked example
Imagine a civil trial about a car accident. A witness, Sarah, gives evidence that the traffic light was green when the other driver entered the intersection. The defendant's barrister cross-examines Sarah about the weather and how far away she was standing — but never suggests to her that the light was actually red, and never puts to her that she is mistaken about the colour.
Sarah leaves the witness box. Later, in the closing address, the defendant's barrister stands up and argues to the court: "Sarah is wrong — the light was red, and you should not believe her." That is exactly the kind of ambush the rule in Browne v Dunn is designed to prevent. Sarah was never given the chance, while she was giving evidence, to explain how she was sure of the colour, or to answer the suggestion that she was mistaken.
Faced with this, the court has options. It might refuse to let the barrister argue that Sarah was wrong. It might allow Sarah to be recalled so the point can finally be put to her. Or it might decide to accept Sarah's evidence more readily, precisely because it was never challenged when it could have been. What the court will not usually do is let the barrister have it both ways — silence at the time, then attack at the end.
What does “putting your case” mean?
"Putting your case" simply means stating your version of events, or your challenge to the witness, directly to that witness so they can agree, disagree or explain. In practice it often sounds like: "I put it to you that the light was red," or "I suggest to you that you did not see what you claim to have seen." The witness then has the chance to respond.
You do not have to put every tiny detail. The courts have made clear that it is enough to put the substance of your case — the real points of difference — not every nuance (see White Industries (Qld) Pty Ltd v Flower & Hart (1998) 156 ALR 169). Trying to put "every possible contingency" to a witness can be oppressive and is not required. Equally, you do not have to put a matter the witness already knows is in dispute — for example, where the issue is obvious from the pleadings, an opening, or a recorded police interview. The whole point is fair notice, and sometimes the witness already has it.
What you must put
- Any direct contradiction — that a fact the witness gave is wrong, or that the truth is your different version of events.
- Any allegation that the witness is lying, has a motive to lie, or has invented or exaggerated their account.
- Any serious attack on the witness’s reliability, memory or honesty that you intend to rely on later.
- The substance of an inference you will ask the court to draw from other evidence that contradicts the witness.
What you need not put
- Matters the witness already knows are disputed — for example, from the pleadings, the opening, or a recorded interview.
- Every minor detail or possible contingency — putting the substance of your case is enough.
- Points that are obvious from the very nature of the case, where fair notice already exists.
- Purely collateral matters that do not go to the real issues in dispute.
What happens if you breach the rule?
This is where most summaries get it wrong. Breaching the rule in Browne v Dunn does NOT automatically mean the witness must be believed, and it is NOT an exclusionary rule that automatically shuts out the contradicting evidence. As the High Court put it in MWJ v The Queen, reliance on the rule “can be both misplaced and overstated.” Instead, the trial judge has a discretion and a menu of possible responses, chosen to fix the unfairness in the particular case. They range from the mild and most common (recalling the witness) to the very rare (excluding evidence):
1. Recall the witness (most common)
The usual cure is simply to bring the witness back so the matter can finally be put to them. In the uniform Evidence Act jurisdictions this is backed by section 46 (“Leave to recall witnesses”). The High Court in MWJ v The Queen [2005] HCA 74 said a party taken by surprise can “almost always” cure the problem this way, without injustice.
2. Adjournment
The court may grant a short adjournment so the witness can be recalled, or so the other side can deal with the new point. In civil cases the party who broke the rule may be ordered to pay the costs thrown away.
3. Taken to accept the evidence
The cross-examiner may be treated as having accepted the unchallenged evidence, and may be barred from arguing in closing that the witness should be disbelieved on that point.
4. Evidence more readily accepted
The court may treat the failure to challenge as a good reason to accept the witness’s evidence — although this is qualified: if the evidence is itself incredible, or is contradicted by other believable evidence, the lack of cross-examination matters far less.
5. Jury direction or comment
In a jury trial, the judge may give a direction or comment explaining the failure and how the jury may (and may not) use it. In criminal trials these directions must be given with great caution — see below.
6. Exclusion of evidence (rare, last resort)
Very occasionally a court may refuse to admit evidence on a point that was never put. This is a last resort, used sparingly, and the position even differs between states — New South Wales recognises the power; Victoria has held there is no such power and that the remedy is comment or direction only.
The rule in criminal cases
In criminal trials the rule applies, but with real caution — because the accused has the right to silence and bears no onus to prove anything. The High Court in MWJ v The Queen [2005] HCA 74 said the principle "needs to be applied with some care when considering the conduct of the defence at criminal trials," and that the rule cannot be applied to an accused "without serious qualification," any more than the related rule in Jones v Dunkel can. As the Court bluntly put it, "it is not for the defence to clear up" inconsistencies in the prosecution case.
The most dangerous situation is where defence counsel fails to put part of the defence case to a prosecution witness, and the prosecutor then suggests to the jury that the accused's evidence must be a "recent invention" because it was never put. The courts have repeatedly warned against this. In R v Manunta (1989) 54 SASR 17, Chief Justice King said this line of reasoning is "fraught with peril and should therefore be used only with much caution and circumspection" — counsel may simply have misunderstood instructions, or the point may have been overlooked. In R v Birks (1990) 19 NSWLR 677, the way the Crown exploited a failure to cross-examine was held to be inconsistent with that need for caution.
The High Court returned to this in Hofer v The Queen [2021] HCA 36. It held that an accused person generally should not be cross-examined, or made the subject of adverse comment, about why their counsel did not put certain matters to the Crown's witnesses — to do so risks reversing the onus of proof. Hofer is now the leading modern authority limiting how the rule can be used against an accused. The practical lesson: in a criminal trial, the usual cure for a failure to cross-examine is to recall the witness, not to invite the jury to convict because of it.
The rule in civil cases
The rule has its fullest force in civil litigation, where both sides carry the burden of proving their own case and there is no right to silence to complicate matters. The leading Australian statement comes from a civil case: Allied Pastoral Holdings Pty Ltd v Federal Commissioner of Taxation [1983] 1 NSWLR 1, where Justice Hunt said that, unless notice has already clearly been given, a cross-examiner must put to an opponent's witness "the nature of the case" on which they propose to rely in contradiction — "particularly where that case relies upon inferences to be drawn from other evidence."
The rule is alive and well in modern civil appeals. In Locke v H C Loneragan & Co Pty Ltd [2025] NSWCA 166, the New South Wales Court of Appeal restated the requirement to put contradictory propositions to a witness, while also showing its limits — there was no unfairness where the allegation was already squarely raised on the pleadings and supported by a large body of contemporaneous documents, so the witness already had fair notice. The rule also shapes what a judge can do: in Kuhl v Zurich Financial Services Australia Ltd (2011) 243 CLR 361, the High Court confirmed that fairness conditions the findings a judge may make against a witness who was never given the chance to respond.
If you are representing yourself
The rule in Browne v Dunn assumes a trained advocate who knows to "put the case." That makes it a trap for self-represented litigants, who often do not realise they must directly challenge the other side's witnesses on every point they dispute. If you are running your own case and you disagree with what a witness says, you generally need to say so to that witness — for example, "I put it to you that what you have just said is not true, because ..." — rather than waiting to argue it at the end.
The courts recognise this difficulty. A trial judge has a duty to ensure a fair trial, which includes explaining the rule to a self-represented person and giving them the chance to put their case before any adverse comment is made about a failure to do so. As one Supreme Court judge has observed, the ultimate responsibility for fairness rests with the trial judge, who can recall witnesses and control the conduct of the trial. Still, you cannot rely on that safety net entirely.

Where the rule comes from (the 1893 case)
The rule was born in an English defamation case heard by the House of Lords in 1893: Browne v Dunn (1893) 6 R 67. A solicitor, Mr Dunn, had prepared a document by which a group of local residents retained him to deal with a man who had been causing them trouble. Several of those residents gave evidence that they had genuinely retained the solicitor. None of them was challenged in cross-examination on whether the retainer was a sham. Yet the other side then asked the jury to disbelieve them and find that the retainer was not genuine.
The House of Lords held that this was unfair. The most famous statement of the rule comes from the Lord Chancellor, Lord Herschell. A second Law Lord, Lord Halsbury, agreed and extended the rule beyond attacks on a witness's honesty to challenges to the accuracy of the facts they had given. Australian courts have applied and refined the rule ever since.
It seems to me to be absolutely essential to the proper conduct of a cause, where it is intended to suggest that a witness is not speaking the truth on a particular point, to direct his attention to the fact by some questions put in cross-examination showing that that imputation is intended to be made … not only a rule of professional practice in the conduct of a case, but is essential to fair play and fair dealing with witnesses.

Key cases on the rule
These are the decisions an Australian court is most likely to turn to on the rule today — from the original House of Lords case to the latest 2025 appeals.
Browne v Dunn
(1893) 6 R 67 (House of Lords)
The origin of the rule. You must put to a witness any matter on which you intend to suggest they are not telling the truth, so they have a chance to explain — a rule of fair play, not mere technicality.
Allied Pastoral Holdings Pty Ltd v FCT
[1983] 1 NSWLR 1 (Hunt J)
The leading Australian statement of the rule. A cross-examiner must put the nature of the case relied on in contradiction, especially where it depends on inferences from other evidence.
R v Manunta
(1989) 54 SASR 17 (King CJ)
Treating a failure to cross-examine as proof of recent invention is “fraught with peril” and must be used only with much caution — there are often innocent explanations for the omission.
MWJ v The Queen
[2005] HCA 74 (High Court)
The modern High Court authority. The rule applies in criminal trials only with serious qualification; the usual cure is to recall the witness; and it cannot be used to reverse the onus of proof onto an accused.
Khamis v R
[2010] NSWCCA 179 (Whealy J)
Sets out the menu of responses to a breach and confirms the rule is not a “preclusive” rule of evidence — excluding evidence is a last resort, not the first response.
Hofer v The Queen
[2021] HCA 36 (High Court)
An accused generally should not be cross-examined, or face adverse comment, about why their counsel failed to put matters to Crown witnesses — doing so risks reversing the onus of proof.
Locke v H C Loneragan & Co Pty Ltd
[2025] NSWCA 166 (NSW Court of Appeal)
A recent civil restatement: contradictory propositions must be put to a witness — but there is no breach where the issue was already squarely raised on the pleadings and the documents.
Lynn v The King
[2025] VSCA 315 (Vic Court of Appeal)
In the high-profile Greg Lynn murder appeal, repeated prosecution breaches — attacking witnesses, and even the Crown’s own expert, on matters never put — were called “indefensible” and caused a miscarriage of justice. The conviction was set aside and a new trial ordered.

Common misunderstandings
⚠️
Thinking a breach means the evidence is automatically thrown out, or the witness must automatically be believed. It does not — the court has a discretion and usually just allows the witness to be recalled.
⚠️
Believing you must put every single detail to a witness. You only need to put the substance of your case — the real points of dispute.
⚠️
Assuming the rule applies to a criminal accused exactly as it does to a civil party. It does not: an accused bears no onus of proof, and the rule is heavily qualified in criminal trials.
⚠️
Confusing the rule in Browne v Dunn (about putting your case to a witness) with the rule in Jones v Dunkel (about not calling a witness at all). They are different rules.
Glossary of terms
Cross-examination
The stage of a trial where a party questions the other side’s witnesses, to test their evidence and put a different version of events to them.
Putting your case
Directly stating your version, or your challenge, to a witness so they can agree, disagree or explain — for example, ‘I put it to you that ...’.
Recall (a witness)
Bringing a witness back to the box so a matter that was missed can be put to them. In uniform Evidence Act states this is governed by section 46.
Exclusionary rule
A rule that keeps evidence out of a trial. The rule in Browne v Dunn is NOT an exclusionary rule — breaching it does not automatically exclude evidence.
Recent invention
An allegation that a witness has made up their account only recently. Suggesting this because a point was not put in cross-examination is dangerous and must be approached with caution.
Rule in Jones v Dunkel
A separate rule allowing a court to draw an inference from a party’s unexplained failure to call a witness or give evidence. It is often confused with Browne v Dunn but addresses a different problem.
Procedural fairness
The basic requirement that a trial be conducted fairly, including that people get a chance to answer the case against them — the principle the rule in Browne v Dunn protects.
Frequently asked questions
What is the rule in Browne v Dunn?
It is a rule of fairness in cross-examination. If you intend to contradict a witness, or to ask the court to disbelieve them, you must first put the substance of that challenge to the witness while they are giving evidence, so they have a chance to respond. It comes from the 1893 House of Lords case Browne v Dunn (1893) 6 R 67 and applies across Australia.
Is it spelled ‘Browne v Dunn’ or ‘Brown v Dunn’?
The correct spelling is Browne v Dunn, with an ‘e’, named after the parties in the 1893 case. It is very commonly written ‘Brown v Dunn’ without the ‘e’, including in some law firm articles, but Browne is correct.
What happens if you breach the rule in Browne v Dunn?
There is no single automatic consequence. The trial judge chooses from a range of responses: most commonly allowing the witness to be recalled (under section 46 of the Evidence Act); granting an adjournment; treating the cross-examiner as having accepted the evidence; accepting the unchallenged evidence more readily; giving a jury direction; or, very rarely, excluding evidence. A breach does not automatically decide the case.
Is Browne v Dunn an exclusionary rule?
No. This is a common misunderstanding. The rule in Browne v Dunn does not automatically exclude evidence — courts have described it as not a ‘preclusive’ rule. Excluding evidence for a breach is a last resort, used only rarely, and the usual remedy is simply to recall the witness so the point can be put.
What does ‘putting your case’ to a witness mean?
It means directly stating your version of events, or your challenge, to the witness so they can respond — for example, ‘I put it to you that the light was red’ or ‘I suggest you did not see what you claim’. It gives the witness a fair chance to agree, disagree or explain before you rely on that point later.
Does the rule apply in criminal cases?
Yes, but with significant caution. Because an accused has the right to silence and bears no onus of proof, the High Court in MWJ v The Queen [2005] HCA 74 and Hofer v The Queen [2021] HCA 36 held the rule must be applied carefully in criminal trials. In particular, an accused should generally not be cross-examined or criticised for why their counsel failed to put matters to prosecution witnesses.
Does the rule apply in civil cases?
Yes — the rule has its fullest force in civil litigation, where both sides must prove their case. The leading Australian statement, in Allied Pastoral Holdings v FCT [1983] 1 NSWLR 1, is a civil case, and it continues to be applied in modern civil appeals such as Locke v H C Loneragan & Co Pty Ltd [2025] NSWCA 166.
Can a witness be recalled if something was not put to them?
Yes. In the uniform Evidence Act states, section 46 lets the court give leave to recall a witness to deal with a matter on which they were not cross-examined. Recalling the witness is the usual and preferred way to fix a breach of the rule in Browne v Dunn.
What must you actually put to a witness?
You must put the substance of your case — the real points you dispute, any suggestion the witness is lying or mistaken, and the inferences you will ask the court to draw against them. You do not have to put every minor detail, and you need not put a matter the witness already knows is in dispute.
Do I have to follow the rule if I am representing myself?
Yes — the rule applies to self-represented litigants too. If you dispute what a witness says, you generally need to put that to them directly rather than only arguing it at the end. A judge should explain the rule to a self-represented person, but it is wise to prepare. Call 1800 951 176 for free guidance.
What is the difference between Browne v Dunn and Jones v Dunkel?
They are different rules that are often confused. Browne v Dunn is about fairness in cross-examination — putting your case to a witness who is giving evidence. Jones v Dunkel is about the inference a court may draw when a party fails to call a witness or give evidence at all. One concerns how you question a witness; the other concerns an absent witness.
What was the case of Browne v Dunn actually about?
It was an English defamation case decided by the House of Lords in 1893. It concerned whether a group of residents had genuinely retained a solicitor. Witnesses said the retainer was genuine and were not challenged on it, yet the other side later asked the jury to disbelieve them. The House of Lords held this was unfair, and the rule was born.
What can a judge do if a lawyer does not put their case properly?
A judge has a range of options to keep the trial fair: allow the witness to be recalled, grant an adjournment, prevent the lawyer from arguing the unchallenged point, give the jury a direction, or order costs in a civil case. The judge’s overriding duty is to ensure a fair trial, and exclusion of evidence is only a last resort.
