Police raided the North-West home of former Lambie chief of staff and ex-Queensland MP Rob Messenger and his wife - former senior Lambie staffer Fern Messenger - on May 12.

The officers had a search warrant, questioned the Messengers and seized computer equipment.

Mr Messenger told the commission police actions may have been misconduct under the Tasmanian Integrity Commission Act.

He argued police had failed to discharge their duties, obligations and responsibilities by not considering all the relevant circumstances, and that the complaint police said led to the raid was vexatious.

Mr Messenger said police used as justification for the search warrant evidence the Messengers had previously supplied to police in good faith in February relating to another former staffer of the Tasmanian crossbench Senator.

Mr Messenger said police told him the raid followed a complaint from the other former Lambie staffer alleging Mr Messenger had breached a section of the Tasmanian Criminal Code relating to stalking and bullying by posting a video.

Mr Messenger said he did not deny posting the video, but it contained no threats.

He said he would vigorously defend any charges relating to stalking or bullying if charges were laid, and that he had been exercising his lawful rights in the interest of the public.

Mr Messenger said the confiscation of the computer gear would severely interfere in matters before the Fair Work Division of the Federal Court.

The Messengers are taking action against the Commonwealth and Senator Lambie involving allegations of unlawful dismissal from employment in Senator Lambie's office in 2017.

The Messengers are representing themselves.

A case management hearing is scheduled for July 10, with a trial scheduled to start on September 21.

The Messengers are seeking to have the other former Lambie staffer subpoenaed to give evidence.

Tasmania Police declined to comment.
