HSU national secretary Kathy Jackson has personally told a Federal Court judge he should disqualify himself, arguing in court she had been denied procedural fairness.

It was an extraordinary morning on the last day of submissions into whether the HSUEast and the east branch of the federal HSU should be placed into administration.

In two hours, Ms Jackson sacked her lawyers, appointed a new one who then said he was unavailable, and made a string of adverse allegations about the conduct of the case so far, including the rejection of any need for an administrator until she had been heard in full.

As the case began, Ms Jackson's barrister Brett Shields told the court his instructions had been withdrawn, as had those of his instructing solicitors.
