The Bass Greens MHA was disappointed Labor chose to "recycle" Bryan Green as deputy premier.

"I was disappointed in Labor, that their standards could be so low," Mr Booth said yesterday.

Mr Green stepped down as deputy premier in 2006 for his involvement in the Tasmanian Compliance Corporation scandal.

He faced two corruption trials but neither jury was able to reach a verdict.

At the time Mr Booth said Mr Green "should never return to a position of responsibility in a government because he is either corrupt or pathologically incompetent".

After the election, Mr Booth told Parliament he was "horrified" Mr Green had been reinstated to the government's frontbench.

He said yesterday the appointment was evidence of a shallow parliamentary talent pool.

Despite Mr Booth's opposition, Greens leader Nick McKim said his party could work co- operatively with Mr Green.

He denied the party room decision to back Mr Green showed the Greens had sold out on their principles.

"Ultimately the reason we made the decision to offer supply and confidence to the Labor government and also to accept cabinet positions was around government stability, it was around good governance, and it was about progressive policy outcomes that address the concerns of Tasmanians," he said.

"It wasn't based any way on personality."

A former anti-Greens attack dog, Mr Green yesterday said his past animosity with the Greens would not impact on the power- sharing agreement.

"The experience in working with the Greens in cabinet and even the Greens members in Parliament has been generally a good one," he said.

"I've genuinely enjoyed not only the company of both Nick and Cassy but their intellect and the way they applied themselves to their job.

"So effectively I don't see that as an issue."
