R v Macdonald; R v Maitland (No 6)

The appeal to the High Court arose from two related cases, R v Macdonald and R v Maitland, where the issue was the discharge of a single juror on the basis of illness and the subsequent continuation of the trial with the remaining jurors. The appellants argued that the discharge of the juror and the continuation of the trial with 11 jurors was a violation of the appellants' right to a fair trial as guaranteed under the Australian Constitution. The High Court was tasked with determining the constitutionality of continuing a trial with fewer than 12 jurors after one juror had been excused due to illness.

The central legal issue before the Court was whether the continuation of a jury trial with 11 jurors after the discharge of one juror on medical grounds was compatible with the constitutional requirement of a fair trial. The Court had to consider whether the right to a trial by jury, as enshrined in section 80 of the Constitution, included the right to a jury of 12 members and whether a trial could constitutionally proceed with fewer jurors under specific circumstances. The Court also needed to examine the legislative provisions that permitted the continuation of trials with fewer than 12 jurors in certain situations and their alignment with constitutional imperatives.

The High Court, in its judgement, concluded that the constitutional guarantee of a fair trial by jury does not necessarily require a jury of exactly 12 members. The Court found that it was within the legislative authority to provide for the continuation of a trial with fewer than 12 jurors in cases where a juror was unable to continue due to illness, provided that the other jurors were satisfied that the remaining jurors were capable of delivering a fair verdict. The Court held that as long as the trial was conducted in a manner that did not compromise the fairness or impartiality of the proceedings, the continuation of the trial with 11 jurors was permissible. Consequently, the Court dismissed the appeal, upholding the constitutionality of the trial proceeding with the remaining jurors.

The final orders of the Court were to dismiss the appeals brought by the appellants, affirming the decisions of the lower courts that the trials could proceed with 11 jurors after the discharge of one juror on medical grounds. The Court's decision clarified the scope of the constitutional right to a jury trial and provided guidance on the legislative framework governing the continuation of jury trials under exceptional circumstances.
