Dispute resolution

JWS is uniquely placed as a Top Tier Dispute Resolution Practice in Australia, handling the largest and most complex litigation across regulatory prosecutions, insolvency, plaintiff and defendant class actions, corporate, commercial and competition and tax disputes. 

There are few firms that can now match JWS across the size, scale and sophistication of its dispute resolution work. No firm of a comparable size has a similar practice. Our partners’ hands on involvement, and our drive and determination to succeed in the cases we conduct in the most cost effective and efficient matter, have seen more and more clients choose JWS for the big ticket claims and defences.

We are renowned for our DR experience and expertise across the spectrum of class actions, insolvency, regulatory claims, corporate, commercial, competition and tax disputes and civil and criminal regulatory investigations and prosecutions for companies, directors and senior executives. We are unique in the market place, combining top-tier capabilities with a service model that promotes the hands-on involvement of our senior lawyers.

We also have considerable expertise in acting for litigation funders who drive class action litigation in Australia. This experience provides us with invaluable insights into the judgment calls made for both plaintiffs and defendants in the conduct of complex claims. Our clients obtain commercially attractive results based on our savvy, strategic and non-process driven advice.

We provide a compelling offer of outstanding litigation services. Our independence and relative conflict-free positioning enables us to pursue plaintiff-based litigation, as well as defendant work.  Our focus on providing strategic advice to Australian funds on class actions puts us in a unique position to prosecute their claims.

We are dedicated to the causes we fight, and to achieving the best case scenario for our valued clients.
