Four more former High Court staff members have made allegations of inappropriate behaviour by former High Court judge Dyson Heydon.

Three of those were allegations of sexual harassment, and one was an allegation of bullying.

The revelations come after High Court Chief Justice Susan Kiefel apologised in June after an independent inquiry by Vivienne Thom had found Mr Heydon had harassed six female former associates. She said at the time that the women had been “believed”.

However, Mr Heydon “categorically denied” any allegation of predatory behaviour or breaches of the law.

Following Dr Thom’s report, the High Court contacted more than 100 former associates who worked at the court during the time Mr Heydon was on its bench.

It invited the associates to talk to Dr Thom about their experiences.

High Court Chief Executive and Principal Registrar Philippa Lynch told senate estimates on Thursday that eight former associates and a former staff member had come forward to provide further information to Dr Thom.

Some of those people had provided further information in relation to conduct that was already the subject of Dr Thom’s investigation, she said.

A High Court spokesman said four of the additional people who had come forward had made fresh allegations, three in relation to sexual harassment, and one in relation to bullying.

“The four individuals who made allegations to Dr Thom were very clear that, although they wanted this information to be provided to the court, they were not making formal complaints and did not expect, or want, these matters to be investigated,” he said.

“Dr Thom did not recommend that any further action be taken in respect of these discussions. Some of the discussions related to Dr Thom’s earlier investigation. Dr Thom advised the Court that those comments did not affect the findings of her earlier investigation and she did not recommend any further action.”

Ms Lynch told senate estimates that the High Court had put in place a new human resources policy for staff who worked in judges’ chambers and revised its induction program.

She also revealed that ACT Policing, a division of the Australian Federal Police, had requested a copy of Dr Thom’s report.

She said the High Court had not provided it with a copy because of concerns about the women’s privacy, but had said it was not opposed to the associates providing the police with the parts of the report that related to them.

She said she had also agreed to seek the permission of the associates to release the report to ACT Policing if it wished to “press” its request for a copy of the report. However, it had not done so.

She said she had also passed on contact details for the relevant police officers to the six associates at the centre of Dr Thom’s initial investigation.

A spokesman for ACT Policing said it had “not received a complaint or allegation from any victim” relating to Mr Heydon.

He said ACT Policing had liaised with the Principal Registrar of the High Court to seek a copy of Dr Thom’s report.

“As no complaint has been received, the report is not required at this time,” he said.

He said ACT Policing had received a request from the ACT Director of Public Prosecutions Shane Drumgold in June to investigate the allegations of alleged sexual harassment by Mr Heydon.

“Investigation referrals of this nature between ACT Policing and ACT DPP are a routine part of operations between the two agencies,” he said.
