Leask v Cwealth of Aust

In *Leask v Commonwealth of Australia*, McHugh J, sitting in chambers, considered an application for an interlocutory injunction. The applicant, Leask, sought to restrain the Commonwealth from proceeding with the prosecution of him for alleged breaches of the *Broadcasting and Television Act 1942* (Cth). Leask contended that the prosecution was an abuse of process and that the Commonwealth had acted improperly in initiating and pursuing the proceedings.

The central legal issue before McHugh J was whether the court had the power to grant an interlocutory injunction to restrain a criminal prosecution, and if so, whether the circumstances of this case warranted the exercise of such a power. This involved considering the principles governing the grant of interlocutory injunctions, particularly in the context of criminal proceedings, and the extent to which a court could intervene to prevent an alleged abuse of process.

McHugh J ultimately refused the application for an interlocutory injunction. His Honour reasoned that the court's power to restrain a criminal prosecution was an exceptional one, to be exercised only in the clearest of cases where the prosecution was demonstrably an abuse of process. He found that the applicant had not established a sufficient case to warrant such an extraordinary intervention, particularly at the interlocutory stage, and that the proper forum for determining the merits of the prosecution and any alleged impropriety was the criminal trial itself.
