The ability to sue for the loss of potential profits is at the heart of ALL of the so-called free trade agreements.  Effectively foreign companies can override the wishes of governments, which can have immense negative effects on environmental, health and safety regulations.  The TPP et al turns over to the corporations the traditional powers of governments, but saddles them with none of the responsibilities of government towards the citizenry.  Cute.
