The Senate has voted to establish an inquiry that will investigate the deal between the Western Australian government and the Commonwealth regarding the Bell Act, and the involvement of Attorney-General George Brandis and former Treasurer Joe Hockey.

"This motion passed today compels Senator Brandis and Senator Mathias Cormann to appear before the inquiry to answer questions about their involvement in this deal," Greens Justice spokesperson Senator Nick McKim said.

"The Greens believe that former Treasurer Joe Hockey should also be called to give evidence."

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."

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 Senate has supported a motion initiated by Australian Greens Senator Rachel Siewert that calls on the Government to address barriers for people with vision impairment to access the National Disability Insurance Scheme.

“Recently we saw reports that blind and vision impaired Australians have not been able to access the NDIS because materials and pamphlets are not in braille or large print.

“A National Disability Scheme that is not accessible to people with disability is disastrous and flies in the face of the whole purpose of the NDIS. 

Reports of up to 2000 people with serious mental ill health and disabilities being turned away because the National Disability Insurance Scheme is at capacity in the ACT is a crisis that must be urgently addressed, Australian Greens Senator Rachel Siewert said today. 

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."
