Overview

Our Class Action Litigation Group helps companies resolve potentially high-stakes class action disputes so that they can get back to the business at hand. From product liability and price fixing to securities and corporate governance issues, we understand the financial, regulatory, reputational and other business impacts and uncertainties associated with these typically complex disputes.

Our clients rely on our unsurpassed depth and breadth of practical experience and litigation expertise, coupled with our unparalleled knowledge of procedure, to inform every aspect of the defence of a class action. Our team employs a pragmatic yet highly creative approach to narrowing (if not eliminating) the claim prior to certification. We then proceed to trial (or resolution, as appropriate) based on the broader business context of the dispute. In doing so, we help our clients achieve meaningful results that align with their business objectives.

,,The team is fantastic: they're smart, kind, responsive and accommodating. The lawyers are always ahead of the game.,,
