Labor and the Greens have criticised the government's Family Law Inquiry and have called for Pauline Hanson to be sacked from the deputy chair position.

Scott Morrison’s decision last year to appoint One Nation leader Pauline Hanson to co-chair an inquiry into the family law system is now “an albatross around his neck”, Labor has said.

Yesterday, all but two Senators voted in support of a motion condemning the remarks of men’s rights activist Bettina Arndt about the horrific murders of Brisbane mum Hannah Clarke and her three children.

There are growing calls for Ms Arndt to be stripped of her Order of Australia medal, which intensified after she supported the notion that Ms Clarke’s estranged husband was driven to kill his family.

Ms Hanson and fellow One Nation Senator Malcolm Roberts were the lone opponents of the motion, which received strong support from the Coalition.

Yesterday, Liberal Senator Jonathon Duniam described Ms Arndt’s comments as “abhorrent and unacceptable” and added that “there are never any excuses or justifications for family violence or the evil that Hannah Clarke and her children experienced”.

This morning, Labor Senator Tim Ayres slammed Ms Hanson, saying she “failed to repudiate Bettina Arndt (and) failed to act and stand up for Australian women”.

“There was never any place for Pauline Hanson’s abhorrent views about family law, about women and children, about family relationships,” Senator Ayres told reporters in Canberra.

“The idea that she was brought by Scott Morrison in to chair that inquiry is an absolute albatross around the neck of the Morrison government.

“They should never have done it. It’s a decision that was always going to end up going badly and it looks pretty crook today.”

In an interview on Today on Monday, Senator Hanson was asked about the murders of Ms Clarke and her children and echoed Ms Arndt’s remarks when she suggested Rowan Baxter may have been “driven to it”.

“Don’t bastardise all men out there, or women for that matter, because these things happen,” she said on the Channel 9 breakfast show.

And on domestic violence she said: “A lot of people are driven to this, to do these acts for one reason or another.”

Last September, the Prime Minister announced an inquiry into the family law system to examine a range of issues, from the power of judges to compel honesty and the impact of courts on children.

One of Senator Hanson’s election commitments last year was to push for an inquiry into the treatment of men in family law matters.

Ms Morrison appointed her co-chair of the inquiry – a move that was condemned by women’s safety advocates and Opposition leader Anthony Albanese at the time.

In light of Ms Hanson’s dissenting vote in the Senate yesterday, pressure has ramped up again on the PM over his decision, with calls for her to be dumped as co-chair.

“The views of (One Nation) are absolutely reprehensible, and it does show the deep dangers of Scott Morrison playing footsie with (them) and dragging them into the Family Law Inquiry and giving Pauline Hanson a bigger voice over the lives of women and children, a person who is an apologist for family violence,” Senator Ayres said.

Labor’s spokesperson for Women, Julie Collins, told news.com.au she has previously raised concerns that witnesses to the inquiry “might not feel comfortable” giving evidence in light of Senator Hanson’s public comments.

“Labor didn’t support the inquiry to begin with because there have been many, many other inquiries into family law in Australia,” Ms Collins said.

“The government should be looking at the outcomes of previous inquiries and acting quickly on the recommendations.”

Labor’s Tanya Plibersek also attacked Senator Hanson’s role, saying her being co-chair of the inquiry was “part of the problem, not part of the solution”.

“The rhetoric that Pauline Hanson has been using is giving a megaphone to those who say that women who leave violent relationships and take their children for their own protection, out of violent homes, are the cause of the violence that happens after they leave,” Ms Plibersek said on Sky News.

“We know the most dangerous time for a woman in a violent relationship is immediately after ending the relationship. I think giving a megaphone to the groups that say things like ‘men who have been driven too far’, excuse this violent behaviour.”

Yesterday, Greens Senator Larissa Waters attacked Senator Hanson and said “these abhorrent attitudes are offensive and they undermine efforts to prioritise children’s safety in the family law system”.

She added: “Will this government now accept that Senator Hanson’s attitude puts children at risk and will you remove her as deputy chair of the family law inquiry?”

Senator Hanson responded, saying: “You have no idea of my previous life and what I’ve been through.

“To sit here and say you need me off the committee … I was the one that drove to have this family law inquiry, what have the rest of you ever done,” she said.

Senator Waters said the right thing to do was to remove Senator Hanson from the inquiry.

“Senator Pauline Hanson gave public support for victim blaming on national television, after previously stating on national radio that women make up claims of domestic violence,” she said.

“Women are now in the impossible position of having to share their lived experience of violence at the family law inquiry where they risk being disbelieved and re-traumatised by its deputy chair.

“The potential effectiveness of this inquiry will be undermined if witnesses don’t think they’ll get a fair hearing so the committee must be depoliticised by Hanson being removed from the deputy chair role.”
