It’s been ten years since the tobacco industry agreed to pay nearly $250 billion to 46 states to settle litigation over the companies’ marketing practices and the costs associated with the health consequences of smoking.

The settlement has protected companies from most civil lawsuits brought by the 46 states and their residents, but it has left room for some types of litigation. And those cases have reached the nation’s highest courts, which means more work for Gibson, Dunn & Crutcher, Jones Day, and other firms that represent the nation’s largest tobacco companies.
