O'Sullivan v Barker J & Ors

The plaintiff, O'Sullivan, sought orders in the nature of certiorari and an extension of time to file an application for an order to show cause. The application was heard in the High Court of Australia before a single judge. The respondents included Justice Barker and Justice McKerracher of the Federal Court of Australia, along with P&O Maritime Services Pty Ltd.

The central legal issues before the High Court were whether to grant an extension of time for the plaintiff to file an application for an order to show cause, and whether to grant the order to show cause itself, which sought to quash a decision made by Justice McKerracher.

The High Court judge refused the plaintiff's application for an extension of time to file the application for an order to show cause, specifically in relation to the decision of Justice McKerracher. Consequently, the plaintiff's application for an order to show cause, filed on 17 August 2017, was dismissed.
