Legal documents describing senator Jacqui Lambie talking about her sex life, using foul language and behaving aggressively in the workplace have been made public, despite the efforts of her legal team.

The material was contained in an initial court submission made by Rob Messenger, the Tasmanian senator's former chief of staff.

Mr Messenger is taking Senator Lambie and the Commonwealth of Australia to the Fair Work Division of the Federal Court, claiming he and his wife Fern Messenger, who was Senator Lambie's former office manager, were unlawfully dismissed in May 2017.

The court documents, obtained by the ABC, showed Mr Messenger's initial statement of claim detailed a number of alleged incidents and complaints regarding Senator Lambie's office conduct, including regular comments about her sex life, aggressive behaviour and use of explicit language.

He claimed Senator Lambie regularly announced to staff words to the effect "I desperately need a root", and that "her excessive alcohol consumption could impact upon her work health and safety and that of the staff working within her office".

Mr Messenger has since made an amended claim which does not contain these details.

But they, and all court documentation relating to the case, were suppressed during an administrative hearing at the Federal Court in Hobart at the beginning of August.

On Thursday that order was lifted by Federal Court Justice Tony Pagone, but Senator Lambie's lawyer, Rick Catanzariti, argued certain elements should still have remained under wraps because Mr Messenger's current statement of claim does not include them.

Lambie's lawyer argues details in claim were 'scandalous'

Mr Catanzariti said some of the matters described in the initial claim were "scandalous in nature" and should be removed on the basis they were designed to "bear cruelly" upon Senator Lambie.

Justice Pagone rejected the application, telling the court "a matter cannot be scandalous if it is relevant to proceedings".

He said the content might be graphic but was relevant to workplace conduct.

Appearing outside the Federal Court in Hobart, Mr Messenger said it would be inappropriate to make a statement, but did offer a brief comment.

"The matter's before the courts, it's still active, so unfortunately any questions you will have we can only answer in court with our hands on the Bible," he said.

He said he and his wife were grateful they would have the opportunity to pursue their claims.

"We're just happy that we're able to tell our story in the court, under oath," he said.

The proceedings are scheduled to continue in October.

'Nothing to hide,' Lambie says

Senator Lambie said Mr Messenger's comments had taken a personal toll on her.

"The fact he's already walked away from his original statement of claim looks like not even he believes the hurtful things he's saying," she said.

"I have nothing to hide. All I have is my reputation, and he's trying to take that away from me."

"Mr Messenger's original statement of claim was full of material that was highly objectionable, prejudicial and embarrassing.

"It was replaced by a new document, yet by quirk of the court rules, the now discarded document becomes available to look at.

"I consider that Mr Messenger's campaign to humiliate me and my office with any false and hurtful claims is an attempt to force me to make concessions in the legal proceedings."
