Claims that outspoken Senator Jacinta Nampijinpa Price defamed an Aboriginal land council head are set to be heard in the Federal Court.
A hearing of the case has been set down for seven days starting from Monday before Justice Michael Wheelahan in Darwin.
A statement of claim by Central Land Council chief executive Lesley Turner says a media release from the senator in July 2024 wrongly suggested he no longer had the support of the majority of council members.
It had been falsely reported that a no-confidence motion had been moved against Mr Turner by council members, the claim says.
The senator's release implied Mr Turner had "behaved so unprofessionally that it warranted his dismissal" and was "unfit to continue to occupy the role of CEO", according to the claim filed to the court.
The Northern Territory senator's assertions were published by the NT News in an article titled, "No confidence motion against Lesley Turner defeated", the claim says.
The newspaper later publicly apologised to Mr Turner and retracted the article.
In October 2024 Justice Wheelahan ordered Senator Price to pay $1500 after her legal team failed to file her defence in time to present at a hearing of the defamation matter.
Senator Price came to prominence in 2023 campaigning against an Indigenous Voice to parliament.
She has long called for an audit of federally funded Indigenous organisations.
in September Senator Price was sacked from her shadow portfolios of defence industry and defence personnel for suggesting the Albanese government favoured Indian migrants because they voted Labor. That prompted Liberal leader Sussan Ley to demand her resignation.
