Attorney-General (NSW) v Brewery Employees Union of NSW, commonly known as the Union Label case, was a landmark decision by the High Court of Australia on 8 August 1908. The case was significant in relation to the endorsement by the majority of the court of the reserved powers doctrine and as the first case to consider the scope of the power of the Commonwealth regarding trade marks. It also addressed who could challenge a law as unconstitutional. There was a strong division in the Court between the original members , Griffith CJ, Barton and O'Connor JJ and the two newly appointed justices, Isaacs and Higgins JJ.
