Are some groups profiting off California's health laws?

A few months ago, a California court ruled that coffee needed a warning label. That ruling has since been overturned. But the court made its first finding at the behest of a little-known nonprofit called the Council for Education and Research on Toxics, or CERT. CERT keeps a low public profile. It was founded by four men - three of them scientists. They don’t talk to the press. CERT seems to do just one thing: sue corporations for alleged violations of Prop 65, the law that requires businesses to post the warnings.
