A parliamentary has heard Tasmania's Premier was told Richard McCreadie was facing potential criminal charges before he announced his reappointment.

The Premier, David Bartlett, announced last year he was temporarily reappointing Mr McCreadie as Police Commissioner.

When he abandoned the process four days later, he pointed to advice from the Director of Public Prosecutions, Tim Ellis.

A parliamentary committee has questioned Mr McCreadie, as well as Acting Commissioner Darren Hine and senior police lawyer Mark Miller.

Mr Hine told the committee he met Mr Bartlett just before the announcement was made, telling him criminal charges were being considered against Mr McCreadie.

"He said that didn't dissuade him," Mr Hine told the committee.

Tim Ellis has told the committee he tried to give similar advice to Mr Bartlett's Chief of Staff, Terry Field.

The DPP said the Government seemed unconcerned about the potential criminal charges.

He said Mr Hine's warning confirmed in his mind that the Government was unconcerned about the possibility Mr McCreadie was leaking information.

"Maybe [they] even want that as a quality," he said.

Earlier, Mr McCreadie told the committee he expected Mr Ellis would oppose him coming out of retirement.

He did not give the reasons why and was further questioned in a closed session.

Mr Miller has also given further evidence behind closed doors.
