Class actions and mass claims can put your business under pressure across multiple markets at once. We defend global businesses in class actions, collective proceedings, mass arbitrations, and multi-party litigation. One international team. One coordinated strategy.
We start with the full picture. How could individual claims become large-scale exposure? What will claimants do next? How could a decision in one jurisdiction affect proceedings elsewhere?
Where claims cross borders, we connect the strategy across jurisdictions. You see your total exposure, not a series of isolated proceedings.
We look for opportunities to stop claims gaining momentum, challenge aggregation or certification, and narrow claimant groups or disputed issues. We anticipate claimant and funder strategies and look for ways to limit claims spreading across jurisdictions. We weigh resolution against your total exposure. And when claims need to be fought, we're ready.
Scale demands control. We use eDiscovery platforms, AI-assisted tools, and purpose-built client portals to manage data and disclosure efficiently. You get clear oversight of proceedings and costs.
