WHO says it is powerful?
When the French refused to let in British beef because of the BSE scare, and were then ORDERED to let it in by the EC, they refused.
When the EC FINED them for refusing, they STILL refused, AND refused to pay the fine - and have not paid it YET!!
It is NOT powerful - they have NO means of enforcing anything, other than witholding funding from offending states. Since they rely on money going INTO the EC from offending countries, this is NOT the punishment it might appear.
France also sidestepped rules over National Airline ownership, and subsidised Air France... with impunity!
POWERFUL? No we have a weak crap government(s) which just keeps GIVING IN without a fight
