Jenkins v The Queen

The appeal in *Jenkins v The Queen* concerned a criminal conviction where the appellant, Jenkins, alleged that the trial judge failed to adequately direct the jury regarding the evidence of a prosecution witness, Verebes. The dispute centred on whether the jury should have been warned about the potential unreliability of Verebes' testimony, particularly given his prior guilty plea to offences related to the charges against the appellant.

The High Court of Australia was required to determine whether the trial judge was obliged to warn the jury that it would be dangerous to convict on the uncorroborated evidence of Verebes, who had pleaded guilty to related offences. Furthermore, the court considered whether, even in the absence of an accomplice warning, the judge should have cautioned the jury that Verebes' evidence was potentially unreliable and required careful scrutiny.

The High Court dismissed the appeal, finding that the trial judge was not obliged to give the requested warnings. The court reasoned that the way the trial was conducted, the issues that emerged, and the use made of Verebes' evidence by both the prosecution and the defence militated against such an obligation. Crucially, the defence did not seek to attack Verebes' credit and, in fact, relied on his evidence to support its case. This tactical approach by the defence, which included not wishing the jury to know of Verebes' guilty pleas, meant that a substantial contest over the primary facts Verebes was called to prove did not arise. Consequently, the judge was not required to give a warning about the dangers of convicting on his evidence or about its potential unreliability.
