In this lecture, Sir Anthony Mason will consider the new formulation of the proportionality test developed over a series of High Court cases on the implied freedom of political communication. The development of this new formulation culminated in its adoption by a majority of the High Court in McCloy v New South Wales (2015) 325 ALR 15;  HCA 34. Sir Anthony will consider its consequences and implications.
