“Investor-state dispute settlement”, or ISDS agreements are perhaps the single most obvious phenomenon in international affairs which conclusively demonstrates the super-sovereignty of multinational corporations. These agreements bind governments to policies dictated by foreign investors, empowering investors with the ability to sue any government for exorbitant compensation if its policies interfere with corporate profit.
If, for example, a newly elected government decided that the natural resources of the country belong to the population rather than to the foreign multinational company which may be extracting them for profit; that government can expect to be taken to a secretive international tribunal of highly paid corporate lawyers in a suit for millions if not billions of dollars in compensation.
In other words, policy is no longer in the hands of the state. Either the state must enact policies which multinationals believe will support their own profitability, or they will be forced to pay the multinationals compensation equivalent to whatever the company believes it might potentially have profited had its prefered policies been enacted.
