At 3pm today, Justice Cameron Mander apologised to the jury for a "frustrating day" and said the trial is adjourned until 10am tomorrow.
The judge said "we are reaching a very critical stage of the trial", adding that he was "anxious to avoid any misstep".
The trial continues tomorrow at 10am, likely with the Crown's closing address, followed by the defence closing address, and then the judge's summing up of the case to the jury.
The jury will then retire to begin its deliberations.
