Citation: R v Mark William Helmhout & Anor [2000] NSWSC 218
Court: Supreme Court of New South Wales (Criminal Division)
Date: 10 March 2000
Judge(s): Bell J
Background
Two accused, Deborah Joy Davidson and Mark William Helmhout, were on trial for what the surrounding evidence indicates was a murder prosecution. During the ninth day of the Crown case, Sergeant Dagwell, the custody manager at Queanbeyan Police Station, gave evidence about the Part 10A protocol he completed when Helmhout was taken into custody on 20 June 1998.
The protocol involved a series of questions displayed on a computer screen, which Dagwell read through in sequence. One question asked whether it was the accused's first time being arrested and placed in police custody. Helmhout's recorded answer was "N" (no), inadvertently revealing to the jury that he had previously been arrested. Neither the Crown Prosecutor nor defence counsel had this particular document in their copies of the protocol bundle, so neither anticipated the disclosure.
Counsel for Helmhout, Mr Corr, applied to discharge the jury on the basis that this evidence of prior criminality carried a real potential for prejudice. The application was stood over overnight before Bell J ruled on it the following morning.
Legal Issues
- Whether the inadvertent disclosure to the jury of the accused's prior arrest warranted the discharge of the jury
- What the applicable legal test is for determining whether a jury should be discharged following an inadvertent and potentially prejudicial event during trial
- Whether a judicial direction to the jury at the time of summing up would be a sufficient and effective remedy
Decision
Bell J declined the application to discharge the jury. Her Honour began by accepting that the disclosure was entirely inadvertent and that no impropriety attached to the Crown Prosecutor or Sergeant Dagwell. The sergeant had simply read the questions and answers from his copy of the document as invited, without any reason to know that the offending question was absent from the copies held by both counsel.
On the applicable test, Bell J rejected the formulation from the Victorian Full Court in R v Knape (1965), which suggested discharge was warranted unless the irregular disclosure "could not in any way affect" the jury's judgment. Her Honour preferred the approach affirmed by the High Court in Crofts v The Queen (1996), which requires a more contextual assessment. Relevant factors include the seriousness of the occurrence in context, the stage of the trial at which the mishap occurred, the deliberateness of the conduct, and the likely effectiveness of a remedial judicial direction.
Applying those factors, Bell J found the accidental disclosure did not create prejudice sufficient to make continuation of the trial unfair. The evidence went no further than establishing a prior arrest, with no suggestion of any prior conviction. Importantly, the trial had already received evidence (without objection) about marijuana and cannabis resin found at Helmhout's premises, and evidence of heroin use before the events in question. Against that background, the additional disclosure of a prior arrest carried comparatively limited prejudicial weight. Neither counsel had reacted visibly to the evidence at the time, minimising any added emphasis it might otherwise have received.
Bell J also decided against giving an immediate corrective direction to the jury, on the basis that doing so would risk drawing unwanted attention to the disclosure. Her Honour instead indicated the direction would be incorporated into the summing up, alongside directions about the drug-related evidence, and proceeded on the basis that the jury would comply with those instructions, consistent with the High Court's observations in The Queen v Glennon (1992) about jurors' capacity to follow judicial directions.

Key Takeaways
- The Supreme Court confirmed that no rigid rule governs applications to discharge a jury following an inadvertent and potentially prejudicial disclosure; the test from Crofts v The Queen (1996) calls for a contextual assessment weighing the seriousness of the occurrence, the stage of the trial, whether the conduct was deliberate, and the likely effectiveness of a remedial direction.
- The narrower Victorian test from R v Knape (1965), which would require discharge unless the disclosure "could not in any way affect" the jury's judgment, was expressly rejected as not accurately reflecting the current state of the law.
- Evidence of a prior arrest, without any evidence of a prior conviction, carries limited prejudicial weight, particularly where other evidence of criminal conduct has already been admitted without objection.
- A trial judge retains discretion to defer a corrective direction until the summing up rather than intervening immediately, where an immediate direction risks giving undue prominence to the inadvertently disclosed material.
- The law proceeds on the footing, as expressed in The Queen v Glennon (1992), that juries acting in conformity with judicial directions will reach their verdicts based on the evidence, and that jurors are capable of setting aside irrelevant and prejudicial information when properly instructed.
