After practising broadly in the areas of commercial litigation, competition and consumer law, regulatory investigations, white collar crime and investor class actions, he was appointed a senior associate in 2008 and partner in 2011. Matthew has completed a Masters of Laws, during which he studied economics at Melbourne Business School.

On behalf of the firm, Matthew has contributed submissions to numerous government reviews. This includes the ACCC’s review of its cartel immunity policy, the review of the unfair contract terms legislation, the Productivity Commission’s review of intellectual property, and the Competition Policy Review (Harper Review), which recommended a number of Arnold Bloch Leibler’s proposed reforms.

As a published author, Matthew has written articles on ACCC prosecutions, contract interpretation and other topics in the Australian Law Journal, Melbourne University Law Review  and the Journal of Contract Law, as well as a chapter in the textbook Regulation, Litigation and Enforcement  (Thompson Reuters, 2011). One of his co-authored articles on contract interpretation was endorsed by the Supreme Court of Western Australia in a multi-billion dollar mining dispute.
