Police have been asked to investigate sexual harassment allegations against former High Court judge Dyson Heydon.
Canberra's director of public prosecutions Shane Drumgold wrote to ACT Policing on Tuesday when he learned of the allegations.
An independent investigation commissioned by the High Court found six former judge's associates were harassed by Mr Heydon when he worked at the court.
Mr Drumgold says he asked police to investigate the claims made by the women and an incident at the University of Canberra in 2013.
"I must stress that communications of this nature between the AFP and DPP are a routine part of operations between the two departments," he said on Wednesday.
ACT Policing, which is a portfolio of the Australian Federal Police, confirmed it had received the request and said the information would be assessed.
Speaking through his lawyers, Mr Heydon, who sat on the High Court bench from 2003 to 2013, categorically denied the women's claims of "predatory behaviour".
"Our client says that if any conduct of his has caused offence, that result was inadvertent and unintended, and he apologises for any offence caused."
Three of the women are pursuing claims for compensation.
If they cannot secure talks with Mr Heydon's lawyers, they will take the matter to the Australian Human Rights Commission and, potentially, the Federal Court.
Attorney-General Christian Porter said it was not a matter in which the government could intervene, as the High Court was independent.
"This is one of those very unique circumstances where the High Court is absolutely and ultimately responsible, as part of the separation of powers doctrine, for complaints and the nature of those complaints," he told 6PR radio.
Former prime minister John Howard defended his government's 2003 decision to nominate Mr Heydon to the High Court.
"I stand by all of the High Court appointments made by my government," Mr Howard told Nine newspapers in a statement published on Wednesday.
Prime Minister Scott Morrison has branded the claims against Mr Heydon "very disturbing" while his predecessor Malcolm Turnbull said the allegations made by the six women were "shocking and appalling".
Labor leader Anthony Albanese said what the women had gone through was a tragedy.
"I find it astonishing, the revelations - they're disappointing, they're shocking, and no doubt there'll be further action as a result," he told reporters.
Mr Albanese said it sent a message to men to change their behaviour and to call out harassment when they saw it.
High Court Chief Justice Susan Kiefel said this week she was ashamed the alleged harassment could have happened at the High Court.
"The findings are of extreme concern to me, my fellow justices, our chief executive and the staff of the court."
In 2014, Mr Heydon headed up a royal commission into union corruption set up by the Tony Abbott-led Liberal government.
The independent report on the allegations against Mr Heydon was prepared for the High Court by former inspector-general of intelligence and security Vivienne Thom.
