Accessory liability for intellectual property infringement: the case of authorisation

Discusses the historical emergence of authorisation's role in attributing accessory liability under copyright law. Reviews the pre-1911 position, the introduction of authorisation by the Copyright Act 1911, and its interpretation by subsequent statutes. Compares UK and Australian approaches, the role of joint tortfeasance, the arguments for extending accessory liability to other areas of intellectual property law, and how this might be achieved.
