Cusack v Jones

In the High Court of Australia, Mr P.L. Cusack, appearing in person, brought proceedings against Mr Frank William Dudley Jones. The dispute concerned Mr Cusack's assertion of a substantive right of access to the court, particularly in relation to litigation involving property, including his matrimonial home, which he sought to recover. Mr Cusack argued that this right should not be barred, given the nature of the matters he was attempting to litigate in lower courts and his recourse to the High Court.

The primary legal issues before the court involved the interpretation of Order 63 rule 6 of the High Court Rules, which had been applied by Justice Toohey. Mr Cusack contended that the wording of this rule contained ambiguity, particularly concerning the definition of "vexatious and oppressive" or "frivolous and vexatious" proceedings. He referred to authorities that had expressed difficulty in defining these terms, citing Justice Roden's summary in *Attorney-General v Wentworth* as a fair basis for assessing whether the power under Order 63 rule 6 ought to have been applied.

Mr Cusack argued that the test for vexatious proceedings involved both subjective and objective grounds. The subjective ground, concerning the intention to annoy or embarrass, he believed had not been suggested or admitted in his case. The objective ground, relating to proceedings brought for collateral purposes, was also discussed, with Mr Cusack referencing historical cases to illustrate this concept. He submitted that the least onerous interpretation of the court's rules should apply in his circumstances, given the substantive litigation and property involved.
