The police investigation - codenamed Operation Emerald - was triggered by dozens of allegations of sexual assault that surfaced on social media.
At the High Court hearing, the man’s lawyer Sam Campbell argued the social media “firestorm”, which included death threats, would restart if name suppression was lifted.
The man’s name was “highly identifiable”, he had no support from friends or family, and he was still young, with prospects for rehabilitation if his name was kept secret, Campbell added.
But the man’s circumstances did not reach the threshold for “extreme hardship”, which had to be proven in order to grant name suppression, Justice McQueen said.
She accepted the man had an identifiable name, that there would be mainstream and social media coverage of the case following publication of the man’s name, and that he had little support.
“These factors will combine to cause him distress and embarrassment that amount to hardship,” she said.
“Ultimately, however, I do not consider that these factors on their own are sufficient to establish that he will suffer extreme hardship following publication.”
The man’s interim name suppression will lapse at 5pm on June 27, unless he appeals Justice McQueen’s decision at the Court of Appeal.
