Attorney-General for the State of South Australia v Henriette Piepkorn

The case before the court involves an application by the Attorney-General for the State of South Australia against Henriette Piepkorn. The central issue is whether Piepkorn should be declared a vexatious litigant under section 39(1) of the Supreme Court Act and be prohibited from instituting further proceedings in any Court of South Australia without the leave of the Supreme Court. The application also seeks a stay of proceedings currently in the District Court. The court was required to determine if Piepkorn had persistently instituted proceedings without reasonable ground, considering actions taken in various jurisdictions.

The court examined the various legal proceedings initiated by Piepkorn in South Australian courts, the Federal Court, the Australian Industrial Relations Commission, the Federal Magistrates Court, and the High Court. Since 1993, Piepkorn has been involved in numerous actions across these jurisdictions, often re-litigating issues already heard and determined or dismissed in South Australian courts. The court found that Piepkorn's actions demonstrated a persistent and stubborn approach to litigation. The court further assessed the Federal Court and Federal Magistrates Court proceedings, which primarily related to bankruptcy and sequestration orders against Piepkorn, revealing a pattern of groundless, nonsensical litigation attempts.

The court ruled that Piepkorn's litigation was vexatious and granted the application. The declaration was made, and orders were granted to prohibit Piepkorn from instituting further proceedings in any South Australian court without leave of the Supreme Court. Additionally, the court ordered a stay of proceedings currently in the District Court. The court found that Piepkorn had persistently instituted proceedings without reasonable ground, and her actions were vexatious as they demonstrated a lack of any arguable defence and were nonsensical. The court's decision was based on the evidence of Piepkorn's extensive history of litigation in various jurisdictions, which indicated a pattern of vexatious behaviour.
