Chambers & Partners Asia Pacific Guide 2022 – Band 1, Dispute Resolution - "Justin continues to be identified by interviewees as being 'without doubt in the top echelons of the senior counsel ranks in Australia,' one calling him 'perhaps the best silk I've ever worked with - supremely talented on his feet and meticulous in preparation,' while another remarks: 'I've never seen a Bench that doesn't give enormous weight to everything he says.' His breadth of practice also wins him plaudits, not only for high-profile commercial work, where he is often instructed on appellate cases, but also in the spheres of insolvency, employment and international arbitration.
