I saw that too and i couldn't believe it. It was a loophole that protected foreign investments. It went something to the fact that if a a company produced a product,and a govt. baned that product in their country, you could sue the govt for loss of profits that you could have made. It goes both ways, the US was screwing over poor mexicans that refused to let a US company to open a toxic waste dump, so they sued the mexican govt. for lost profits and won a setttlement for 16M. In canada, the govt wanted to take out an additive to gasoline that a US refinery was making that was harful to peoples health, and when the canadian govt. wanted to ban it, the US company threatened to sue them. Another one was when the canadian govt wanted to do something to cigarette package warnings and the Big Tobacco companies here threatened to sue.
