Heyl Royster

Class Action & Mass Tort

Relying on a tested team approach, our attorneys become impassioned advocates for our clients.

By its very nature, class action/mass tort litigation places the client at tremendous risk, risks that include extensive litigation costs and resources, dangerous legal precedents spurring copycat litigation in other jurisdictions, and, most significantly, exorbitant liability exposure. Heyl Royster understands that these claims place enormous burdens on companies that need to focus their resources on business rather than legal challenges. Heyl Royster advocates for firm clients in defense of class action and mass tort claims relying on a tested team approach that enables us to learn the client's business and become impassioned advocates.

Heyl Royster was very well positioned to respond to the burgeoning class action filings in plaintiff-friendly Illinois venues in the 1990s and early 2000s. During that time, Illinois became a battleground where many class action attorneys sought to obtain certification of national classes in state court venues, often seeking to apply Illinois law to class members who had no contact with the state. Heyl Royster's role in advancing the law regarding issues such as improper venue, choice of law provisions, improper application of state consumer laws in class contexts, and over-broad class certifications continues today.
