CANBERRA, Australia (AP) — A judge on Thursday discharged a jury in the high-profile trial of a former government advisor charged with raping a colleague in the Australian Parliament House because a juror had brought a research paper on sexual assaults into the jury room.

Australian Capital Territory Chief Justice Lucy McCallum said a juror had undertaken research in relation to the case and brought it into the room where a panel of 12 had been deciding their verdict.

A court official had discovered the research paper in the room late Wednesday. The jury was supposed to reach its verdict solely on the evidence presented during the 12-day trial.

Former ministerial advisor Bruce Lehrmann, 27, had pleaded not guilty in the Australian Capital Territory Supreme Court to a charge of sexual intercourse without consent in a minister’s office in March 2019 after a night of heavy drinking. He faced a potential 12-year prison sentence if convicted.

His alleged victim, then his 24-year-old junior colleague Brittany Higgins, reacted to the news of a mistrial with a searing attack on the justice system.

“I chose to speak up. Speak up against rape, speak up against injustice, to speak up and share my experiences with others. I told the truth no matter how uncomfortable or unflattering to the court,” a tearful Higgins told reporters outside court.

“Today’s outcome does not change that truth. But I did speak up, I never fully understood how asymmetrical (the) criminal justice system (is), but I do now,” she added.

The Associated Press does not usually identify alleged victims of sexual assault, but Higgins has chosen to identify herself in the media.

She recounted how she was questioned for days in the witness box and forced to surrender her telephones, messages, photos and data to Lehrmann’s lawyers. Lehrmann exercised his right not to give evidence. His lawyers argued there had been no sexual contact.

“My life has been publicly scrutinized, open for the world to see. His was not,” Higgins added.

Lehrmann declined to speak to the media as he left the court. He has not been held in custody since he was charged and remains free on bail until Feb. 20 when a retrial could commence.

Prosecutors have yet to decide whether a retrial will go ahead.

The jury had been deliberating its verdict since the trial ended on Wednesday last week.

The jurors sent a message to the judge on Tuesday saying they could not reach a unanimous verdict, but she told them to continue deliberating.
