Class Actions

Market-leading class action lawyers

We have been on the cutting-edge of class action litigation for almost 30 years, acted in many seminal class actions, and been at the heart of the development of class actions law, so we deeply understand the issues which drive class actions – and how to defend them.

Our experience covers a broad cross-section of the class action subject-matter that has been conducted in Australia. As a full service firm, we have lawyers with diverse skills and experience, across a range of sectors, and our long track record gives us real knowledge of the Australian class actions landscape.

And that mix doesn't stop at Australia's borders. Strong whole-business connections with leading firms around the globe allow us to exchange knowledge and expertise with our international connections, and maintain an up-to-date understanding of international legal developments, and what they mean for our clients. And when we create the right team for your defence, we tap into an extensive network of the best international lawyers and experts.

The CU class action team have extensive experience in various jurisdictional class action regimes around Australia. This experience allows them to deliver pragmatic advice to their clients to assist with defence / settlement strategies in a confident way.

Demonstrated experience in the strategic defence of class actions proceedings

Successful defences of class actions are about more than just knowing the law. We've learnt from running class actions from initial challenge right through to trial and remediation that there's no single right way to manage a class action successfully which meets our clients' legal and commercial objectives.

That's why we create a bespoke strategy to advise you on your class actions risk, defend actions, devise innovative resolutions in mass claims and manage the issues that arise along the way.

You'll understand all your options when faced with a class action, so you can choose the strategy that's right for your business and your business needs – from early settlement to pursuit of litigation through to the last appeal – and one that complements your regulatory and reputational responses.
