Kane Dallow disobeyed the Federal Court by republishing allegations contained in videos he had been ordered to take off the internet and "scandalised" the same court by alleging it was involved in "ring of protection" of politicians, Federal judge David O'Callaghan said on Monday.

Tasmanian MP Michael Ferguson began defamation proceedings against Dallow last year, and Dallow has already been found in contempt of court during these proceedings.

Jusitce O'Callaghan said Dallow "intentionally disobeyed the orders" of Justice Richard White by publishing a video in early March called "Broken Parliament" to his website TasNews24 and on YouTube, and published a post on Twitter containing a link to the video.

The judge said the video republished his allegations against Michael Ferguson, and further implicated the Federal Court.

"[He] is guilty of contempt of court, in that, in the fourth video he included the following words: 'The ring of protection is hard at work as the politician in this case is being protected by every level of the Government and sadly more to the point by the Courts'," Justice O'Callaghan said.

"Such a contempt, involving as it does the assertion that a member of the Executive can have a court do his or her bidding, is a serious one."

Dallow had represented himself in the matter Justice O'Callaghan said the submissions he made were "absurd".

"Mr Dallow submitted that when he referred to the 'Courts' being involved in a 'ring of protection' he was 'not actually referring to the Federal Court', and was in fact 'referring to another court'," the judge said.

"I reject Mr Dallow's submission. It is self-evidently absurd."

Justice O'Callaghan adjourned the matter for a penalty hearing next Monday.
