Andreas is a dispute resolution lawyer specialising in complex, high-stakes litigation and investigations across a range of jurisdictions and a variety of industries, as well as in class action litigation, acting for both plaintiffs and defendants.
High stakes matters he has acted in include acting for ASIC in landmark Federal Court proceedings against the ANZ Bank concerning the alleged rigging of the Bank Bill Swap Rate, acting for a US based company operating in the nutraceuticals industry in “bet the firm” litigation seeking to unwind share sale agreements and seeking $175 million in damages, and acting for the former CEO of Leighton Holdings Limited (now CIMIC Group Limited) in connection with AFP and ASIC investigations into alleged foreign bribery.
Andreas also has significant experience acting in class action litigation, including acting for the class of over 400,000 group members in proceedings against subsidiaries of Insurance Australia Group which resulted in the second highest class action settlement in 2020 of A$138m, and defending Merivale in class action proceedings alleging the underpayment of its workforce by a claimed $129m.
Because he acts for litigation funders, plaintiffs and defendants in class action litigation, he has significant insight into the strategies and tactics deployed by all stakeholders in class action disputes.
Clients describe Andreas as having “excellent legal analysis and strategy”, “incredible attention to detail and a keen sense of effective litigation strategy” and being “very calm and focussed”.
