Former Queensland treasurer Curtis Pitt has been dragged into the saga surrounding minister Mark Bailey's private email account.
Mr Bailey came under fire again last week after it was revealed former Electrical Trades Union state secretary Peter Simpson sent executive Mark Algie's CV to the former energy minister for a government board role.
The email, sent to Mr Bailey's personal account, came almost two months after applications for the position closed.
But Mr Algie was appointed to the $60,000 a year role two weeks later.
Premier Annastacia Palaszczuk on Tuesday said she believed the CV was already with the Department of Treasury, and that it came to cabinet through Mr Pitt, then the treasurer, who was the responsible minister.
Ms Palaszczuk repeatedly refused to say if Mr Algie's CV was with the Department of Treasury before applications for the position closed.
"Cabinet can appoint anyone to a board at any time," she said.
"It went through the cabinet process. I am happy with that process."
She also reiterated she had no problem with Mr Bailey's refusal to release his private emails, which were obtained by media through freedom of information requests.
"They're the laws that apply equally to everyone," she said.
"Everyone knows that."
Mr Bailey was cleared of corrupt conduct following a Crime and Corruption Commission investigation, but the watchdog said the practice of ministers using private emails gave the impression of corrupt conduct.
It recommended the ministerial handbook be changed to ban ministers from using personal emails, which the government agreed to.
New rules are expected to be handed down within a week.
