A blogger and businessman has been barred from filing court cases without the permission of a High Court Judge.
Vincent Siemer is already barred from filing new cases relating to an ongoing dispute with the former Vector chairman Michael Stiassny.
Over the years Mr Siemer has filed lawsuits against many individual judges, the Attorney-General and the Judicial Conduct Commissioner.
In a ruling, Justice French said he had continued to be a vexatious litigant, challenging every adverse ruling, and then trying to have them reconsidered, even in litigation unrelated to his initial dispute with Mr Stiassny.
Mr Siemer also publishes a blog that's critical of leading judges.
