In most democratic countries, the laws are proposed either by the Executive (i.e. The government) or by the legislative power. But once it has been proposed it automatically falls into the Parliament's hands which alone can decide to vote, amend or reject it. This precisely sends back to the check and balance theory establishing a separation of power. The representative democratic system creates a government accountable before the parliament and a parliament accountable before the citizens. It is thus the citizens that hold the essence of power.
The EU is an umbrella grafted on top of all Member States, with its own rules and decisions. One of its particularities is that most of the laws generated at the EU level are enforceable in all the Member States. This is called the Supranationality. Because of its deeply undemocratic way of functionning and the very extended executive power at the EU level, national governments do play a bigger rôle in the law-making process by working at the EU level. The national parliaments are then left behind the national Ministers (who vote in the Council) and the more they can do is to pressurise the Ministers to vote in a way or in another. But if the law passed despites a negative vote from the Minister, it is enforceable in the Member States, no matter if the citizens agree or disagree with it. Suddently, the link is broken between the representants and the citizens, and slyly the level of democracy is lowered.
