One Oath Is Enough: High Court Restores a Conviction After Jurors Swore Their Separation Oath on Day One

In The King v Bechaud [2026] HCA 36, the High Court of Australia (Gageler CJ, Gordon, Gleeson, Jagot and Beech-Jones JJ) dealt with a narrow but practical question about Victorian jury trials: when must jurors take the "separation oath" that lets them go home overnight once deliberations have begun? A majority of the Victorian Court of Appeal held that taking it on day one, rather than just before the first separation, made the trial miscarry. The High Court unanimously disagreed. The Crown's appeal was allowed, the Court of Appeal's orders were set aside, and the respondent's appeal against his conviction was dismissed (Orders 1–2; [4], [36]). The important point is that s 50 of the Juries Act 2000 (Vic) requires only that each juror has taken the oath before separation is allowed. It says nothing about when, and an oath, once taken, continues to bind ([15], [18], [25], [29]). All paragraph references below are to the judgment.

Why it matters: Jurors routinely go home overnight during deliberations. A trial is not derailed simply because the separation oath was administered early, but reminding jurors of it before each separation is still good practice, and in some circumstances failing to do so could be an error ([29]).

🧩 Facts and Issues

Background

The respondent stood trial before a judge and jury in Victoria in July 2024 on two charges of rape, to which he pleaded not guilty ([5]). On the first day, after empanelment, the trial judge gave preliminary directions, including a warning not to discuss the evidence with anyone outside the jury, and each juror took the separation oath before going home ([5]–[7]). The judge gave no reasons for administering it at that point ([7]).

The prescribed oath (Sch 5 to the Act) is a promise not to discuss "with any person other than another member of this jury any matter relating directly or indirectly to the evidence in this trial or the deliberations" ([2]).

How the case got here

The jury retired to consider its verdicts on Friday, 2 August 2024, nine days after taking the separation oath. That afternoon, without objection, the judge allowed the jury to separate (go home) for the weekend, without reminding the jurors of their oath ([8]). The same thing happened on Monday, 5 August ([9]). On Tuesday, 6 August, the jury acquitted the respondent on the first charge and convicted him on the second ([9]). Neither the prosecution nor the defence ever asked the judge to remind the jury of the oath ([10]).

On appeal, a majority of the Court of Appeal (Priest and Kaye JJA) held that the oath must be administered at a time "both temporally proximate, and necessarily connected" with the first separation during deliberations. They found a "fatal and fundamental irregularity", quashed the conviction and ordered a new trial ([3], [11]–[12]). Taylor JA dissented: s 50 simply makes the oath a precondition, and an oath once taken endures ([13]–[14]).

What each side argued

• The Crown (appellant): The majority misconstrued s 50; there was no irregularity and no substantial miscarriage of justice ([3]).
• The respondent: The oath had to be taken shortly before separation was "imminent". In the alternative, s 50(2) should be read as requiring a close "temporal or factual connection" (such as a reminder), or as if it said "has [just] taken" ([24]–[25]). As a fallback, he argued that the judge's discretion to let the jury separate miscarried because of the time that had passed and the absence of any reminder ([33]).

The issues

• Does s 50 of the Juries Act 2000 (Vic) require jurors to take the separation oath shortly before the judge first allows them to separate during deliberations?
• If not, did the trial judge's discretion to allow the jury to separate nonetheless miscarry?

⚖️ Applicable Law – Legislation, Rules and Principles

• Juries Act 2000 (Vic), s 50(1): the court "may" allow the jury to separate "after the jury has retired to consider its verdict and before the verdict is given or the jurors are discharged" ([1]).
• Juries Act 2000 (Vic), s 50(2): the court may allow separation "only if each separating juror has taken an oath or made an affirmation in the form of Schedule 5" ([1]). In plain English, the oath is a gateway that must be passed before the judge can exercise the discretion.
• Juries Act 2000 (Vic), s 42: by contrast, the empanelment oath must be taken "[o]n being empanelled", which is an express timing rule ([17]).
• Juries Act 2000 (Vic), s 78A: prohibits jurors from making enquiries about the trial, including by consulting another person ([28]).
• Criminal Procedure Act 2009 (Vic), s 276(1)(b): a conviction appeal succeeds where there has been an error or irregularity that results in a substantial miscarriage of justice ([4], [35], fn 2).
• Statutory interpretation: the Court read s 50 by reference to its text, its statutory context (Pt 6, "Jury trials") and its purpose ([15]–[23]).

📌 Authorities Relied On

• Brownlee v The Queen (2001) 207 CLR 278: a jury must deliberate uninfluenced by outsiders. The law has moved away from strict sequestration towards trusting jurors to follow directions, and the ultimate protection lies in jurors' own sense of responsibility ([20]–[21]).
• R v Patton [1998] 1 VR 7: under the predecessor provision (s 51A of the Juries Act 1967 (Vic)), jurors need not re-swear the oath on each separation, and it should be assumed they understand it continues to bind them ([23], [27], [29]).
• Youssef (a pseudonym) v The Queen [2019] VSCA 240: the oath is a safeguard designed to protect deliberations from contamination. The "best practice" of administering it when separation is first allowed, and of later reminders, was referred to ([14], [23]).
• R v Chaouk [1986] VR 707: the strict common law rule that s 50 relaxes ([23]).
• House v The King (1936) 55 CLR 499: the categories of error for a discretionary decision, invoked by the respondent's fallback argument ([33]).

🧠 Analysis

Issue

Was there an "error or irregularity" in the trial because the jurors took the separation oath on day one rather than just before they first separated during deliberations?

Rule

Section 50(2) makes the oath a precondition to the exercise of the discretion to allow separation. It does not prescribe a time ([15]). A statute is not to be read as containing limits "not apparent from the text, context or purpose" ([15]).

Application

The words "has taken" contain no timing requirement

The Court held that, apart from operating as a precondition, "nothing in the text of s 50 supports a conclusion that the separation oath must be taken at any particular time or stage of the trial process" ([15]). The oath itself refers to "the evidence in this trial" as well as "the deliberations". So it is not confined to deliberations, and taking it early binds jurors from that point ([16], [28]).

Context: Parliament knew how to set a deadline when it wanted one

Other provisions in the same Part of the Act fix precise timing. The empanelment oath, for example, must be taken "[o]n being empanelled" (s 42). The absence of any timing words in s 50 was a contextual signal that Parliament did not intend to impose one ([17]–[18]).

Purpose: protecting the verdict does not require a "fresh" oath

The purpose of s 50 is to balance jurors' ability to go home during long deliberations against the need to protect the verdict from outside influence ([22]–[23]). That purpose can be met by an oath taken early. Administering it when separation is first allowed is "best practice", but s 50 is "sufficiently flexible" to accommodate the course taken here ([23]). Early administration may even serve the purpose better, reinforcing the usual directions and the ban on juror enquiries in s 78A ([28]).

An oath does not fade with time

The Court rejected the idea that an early oath becomes "futile or diluted": "The enduring efficacy of an oath taken by jurors should not be doubted merely because of the passage of time" ([25], [29]). Both alternative readings failed. Reading in "just" would wrongly imply a new oath before every separation, contrary to Patton ([26]–[27]).

Reminders are still good practice, and sometimes required

The Court did not endorse silence. It said reminding jurors of the oath each time they separate "remains appropriate". It also said there may be circumstances, such as a question from a juror suggesting a misunderstanding, in which failing to give a reminder could itself be an error or irregularity ([16], [29]).

Modern practice points the same way

Separation during deliberations is now routine across Australia, and nothing in the legislative history or current practice supported a timing constraint ([30]–[32]).

The discretion did not miscarry either

On the fallback argument, the Court found no factual basis for concluding that the judge overlooked the time that had passed or the absence of a reminder. The decision to allow separation was "anything but unreasonable", especially in "this relatively short trial" ([34]).

Conclusion

There was no error or irregularity, so there was no substantial miscarriage of justice. The majority of the Court of Appeal misconstrued s 50 ([35]).

🏛️ Outcome, Orders and Costs

The appeal was allowed. Orders 2 to 6 of the Court of Appeal's orders of 4 December 2025 were set aside and replaced with an order dismissing the respondent's appeal against his conviction (Orders 1–2; [36]). The retrial ordered by the Court of Appeal will therefore not proceed, and the conviction on the second charge stands. The verdict of not guilty on the first charge was not affected. The judgment does not deal with costs, and costs orders are unusual in criminal appeals.

🧭 Practical Lessons

• For self-represented litigants: An appeal court asks whether a legal rule was actually broken and whether that mattered. Pointing to a departure from "best practice" is not enough if the statute itself was complied with ([23], [35]).
• For self-represented litigants: An argument that asks a court to add words to a statute (here, "just") faces a steep climb ([24]–[27]).
• For practitioners: In Victoria, a separation oath taken at the start of the trial satisfies s 50(2). Ask for a reminder before each separation anyway, particularly if anything suggests a juror misunderstands their obligations ([29]).
• For practitioners: Raise jury-management concerns at trial. Here, neither side asked for a reminder ([10]), and a discretion challenge on appeal needs a factual foundation ([34]).

🧠 Take-Home Lesson

• A statutory precondition means what it says: "has taken" is satisfied by an oath taken earlier in the trial.
• An oath endures. Courts assume jurors understand it continues to bind them unless something suggests otherwise.
• Best practice (regular reminders) is still expected, but it is not the same as a legal requirement.

"An oath, once taken, keeps binding. Remind jurors of it, but a missing reminder is not automatically a miscarriage of justice."
