The Greens will tomorrow move to refer matters associated with the Bell Group Companies Act (WA) to the Senate Legal and Constitutional Affairs Committee.

"The allegation that Senator Brandis instructed the Solicitor General to effectively run dead in the High Court are the most serious he has faced in a career that is strewn with misconduct," Greens Justice spokesperson Senator Nick McKim said.

"We need to get Senator Brandis out of witness protection and into an inquiry where he can be questioned about these extraordinary allegations."

Leader of the Australian Greens Party Dr Richard Di Natale has called on the government to put the interests of farmers ahead of their wealthy mates and support the Greens’ compromise plan on the backpacker tax.

“If this was a tax cut for Gina Rinehart, the National Party would be supporting it.”

“The simple solution here is to tax backpackers like Australian residents so that they are eligible for the tax-free threshold and then pay tax on money they earn after that.”

If reports of George Brandis instructing the former Solicitor-General to act in a political way and ignore the rule of law are true, he should immediately resign or be sacked as Attorney-General.

"It appears Senator Brandis was trying to interfere with the Solicitor-General to stitch up a politically cosy deal for the Western Australian Liberal Government," Australian Greens Justice spokesperson Senator Nick McKim said.

"If it looks like corruption and smells like corruption, then it probably is corruption."

The prime minister's confirmation that Gillian Triggs will not be reappointed as President of the Human Rights Commission is the final indignity in a sustained campaign against an eminent Australian.

"Professor Triggs has faced a series of deliberate, politically motivated attacks for nothing more than doing her job," Greens Justice spokesperson Senator Nick McKim said.

"Having failed to induce Professor Triggs to resign, the government has resorted to sacking her."

"She should regard the way she has been treated as a badge of honour."

The Federal government, Labor and One Nation have banded together to vote in further reductions in civil liberties in the name of 'national security'.

"It is very worrying that control orders will now apply to children as young as 14, and we have been given no evidence that this measure will make Australians any safer," Greens Justice spokesperson Senator Nick McKim said.

"As they have done far too often in recent years, Labor has waved this legislation through Parliament for fear of being seen as 'weak' on national security."

Justin Gleeson SC has been run out of office by a government with no regard for proper process or the rule of law, Greens Justice spokesperson Nick McKim says.

"Mr Gleeson's resignation letter makes it clear that he is sticking to his guns," Senator McKim said.

"There was no doubt a breakdown in trust between the Solicitor-General and the Attorney-General, but this can be laid squarely at the feet of Senator Brandis."

Attorney-General George Brandis' disregard for the rule of law and abuse of process calls into question his suitability for the role, Australian Greens Justice spokesperson Nick McKim says.

"Senator Brandis has basically been caught out shopping around for politically convenient legal advice on some of the most contentious issues facing the government," Senator McKim said.

"For the Attorney General to have sidelined the Solicitor General when considering the constitutionality of contentious legislation is an extraordinary development."
