This article looks at what needs to be proven in order to prevent an adjudication decision being enforced before the Court makes its determination. The recent Supreme Court decision in Karam Group Pty Ltd v Earthmoving Contractors Pty Ltd deals with the common circumstance where an interim injunction is sought while an alleged jurisdictional error of an adjudicator is determined by the Court.
