Andreas Piesiewicz Partner

Meet Andreas

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.

His experience ranges from advising high profile directors and officers of ASX listed companies in the finance and construction industries in relation to securities and foreign bribery related investigations conducted by ASIC and the AFP; to seeking urgent interlocutory and final relief in expedited Commercial List proceedings concerning the market for nuclear medicine technology and associated distribution rights; to prosecuting a $100 million plus negligence claim against a big four accounting firm; to defending a US based company operating in the nutraceuticals industry in Federal Court proceedings seeking to unwind share sale agreements and seeking $175 million in damages. 

He recently acted for ASIC in landmark Federal Court proceedings against the ANZ concerning the alleged rigging of the Bank Bill Swap Rate, and he otherwise has significant experience acting in class action litigation. 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.
