Contempt questions over Buswell cover-up

The West Australian opposition has questioned whether misleading information provided to parliament by Troy Buswell's chief of staff qualifies as breach of privilege and contempt of the Legislative Council.

A Corruption and Crime Commission report this week concluded Rachael Turnseck engaged in misconduct by providing misleading information about the former treasurer's late-night car crashes as he drove home from a wedding in February 2014.

WA Labor's leader of the Legislative Council, Sue Ellery, called on Thursday for the matter to be referred to the Standing Committee on Procedure and Privileges.

"The parliament was misled," Ms Ellery said.

She also put the spotlight on communications between Ms Turnseck and Premier Colin Barnett's deputy chief of staff, Stephen Home.

"It is my contention that this report reveals that it was not just Ms Turnseck but at least Mr Home and others who were informed of Ms Turnseck's intention to mislead," Ms Ellery said.

"Who were those others and to what extent were deliberate actions taken to continue misleading the parliament?"
