Constitutional judiciary is an institution ensuring the effectiveness of the rule of law par excellence. It is because of the constitutional judiciary that a constitutional state is described not only as a country with a constitution, but as a state with a constitution, which is legally enforced.
In this text, we concentrate on one particular aspect of the activities of the Czech Constitutional Court in development of the rule of law as a concept limiting the legislature - not the limits of the content of laws, but limits of the ways in which laws are created. Standards of higher law can therefore be used to test the aim as well as the way.
