Andrew Higgins received an Australia Day Award for his work on the Investor State Arbitration, Philip Morris Asia v Australia in respect of Australia's introduction of tobacco plain packaging laws. The  Tribunal recently dismissed Philip Morris' claim on jurisdictional grounds. Andrew has acted as Special Counsel for the Australian Government since 2011 on the constitutional, investor state arbitration and WTO challenges to its tobacco plain packaging laws. The constitutional challenge was dismissed in 2012 and the WTO challenge is ongoing.

Separately, Andrew was recently re-appointed to the World Health Organisation's Framework Convention on Tobacco Control expert group on Article 19 "Liability" on behalf of the Union for International Cancer Control. Andrew was first appointed to the group in 2013 and authored the group's review of international best practices on civil and criminal liability for tobacco. The group's mandate was extended by the 6th Conference of the Parties.
