Aim of this Diploma Thesis is to have a closer look at current powers of National Parliaments of the Member States to influence legislative process of the European Union. The main question is how do National Parliaments control legislative process in practise. Theoretical Framework is based on a debate about Democratic Legitimacy of the European Union. First the term needs to be defined and basic arguments about the (non)existence of Democratic deficit need to be introduced, then the research question can be introduced. The main focus is on Early Warning Mechanism and a process of issueing of reasoned opinions. An assumption is that through a process of issueing those reasoned opinions by National Parliaments that consist of a democratic elected political parties a Democratic Legitimacy of the European Union could be strenghtened. It is a one-case study of Czech Parliament. All the reasoned opinions, that Czech Senate and Czech Chamber of Deputies issued, will be analysed.
