The US government and European Commission insist that the inclusion of a corporate sovereignty chapter in the TAFTA/TTIP treaty will not in any way diminish the ability of nations to pass laws as they wish. A fascinating case involving an investment in Romania shows why that‘s just not true. It concerns a state aid scheme instituted by Romania to attract investments in the country, which offered tax breaks or refunds of customs duties on raw materials. The scheme was supposed to remain in place for 10 years. But as part of Romania‘s accession to the EU, it was required to cancel this scheme, which was regarded by the European Commission as providing unfair state aid. So, obediently, Romania abolished the scheme in 2005, some years earlier than it had promised.
