Th jury was discharged on Friday afternoon after being unable to reach a unanimous verdict.
The jury foreman told Justice Sarah Huggett there was no prospect of reaching agreement if more time was allowed.

Justice Huggett thanked the jury for their care and attention in considering the matter and told them not to look on the outcome as a failure of their duty.
"It does happen on occasions that juries are not able to reach a unanimous verdict," she said.
"Please don't look on this as a failure.
"You have considered the evidence, you have listened and the system is working if, in fact, you reach the decision you cannot reach a unanimous verdict.
"I thank you on behalf of the community."
Justice Huggett reminded the jury members it was an offence to talk about anything that transpired in the jury room as there was the potential to influence further proceedings.
"Whether these proceedings are retried is up to the Director of Public Prosecutions," she said.
The matter will return to court on February 26.

The jury is considering its verdict in the trial of a police Highway Patrol officer charged over a crash in which Cronulla woman Gai Vieira was critically injured in 2018.
Justice Sarah Huggett completed her summing up on Thursday morning before the jury retired at 10.45am.
The judge told the 12 members of the jury to take as long as they needed to reach a unanimous decision.
Senior Constable Harry Thomas Little, 42, pleaded not guilty to dangerous driving occasioning grievous bodily harm.
Mr Little was pursuing a driver, who was suspected of using a mobile phone, in a westerly direction on Kingsway at Cronulla when his Ford Falcon collided with Mrs Vieira's Mercedes, which was turning right from Connels Road.
The police car was clocked at 133km/h one second before the crash.
Mrs Vieira, who was 68 at the time, was critically injured, and crown prosecutor Carl Young told the court she was left with a brain injury "from which she will likely never recover".

Her three-year-old grandson, who was travelling in the back seat, was uninjured.
The Crown and defence agreed Mr Little accelerated quickly to 122km/h, "braked heavily and slowed" to about 73km/h to move around an L-plater and then accelerated again once back in the right lane.

Witnesses who were driving on Kingsway at the time testified they did not see police lights or hear a siren.
The defence argued Mr Little genuinely believed he had activated the warning lights.
