According to the U.S. Safe Drinking Water and Toxic Enforcement Act, warning labels should be used to inform consumers when a product contains one or more of around 900 chemicals believed to cause cancer or birth defects. Private citizens, advocacy groups, and attorneys are allowed to sue on behalf of the state and collect a portion of the civil penalties for failures to provide the warnings.
There are still a couple of weeks for the defendants to appeal the ruling.
The World Health Organization (WHO) removed coffee from its list of "possible carcinogens" in 2016.
Some coffee drinkers say they'll give coffee drinking a second thought after the ruling, while others say that nothing can stop them from treating themselves to a few cups of coffee a week.
