The Legislative Function
The adoption of laws is the primary task of any parliamentary body. In a parliamentary system, the parliament can be the sole legislator; the other possibility is the combination of parliamentary legislation with the adoption of acts through direct democracy, especially a statewide referendum. In the Czech Republic, the Parliament is currently the sole legislator; nevertheless, the Constitution does not preclude direct democracy in future even in the exercise of legislative power, including the constitutional function.
(1) The people are the source of all power in the state; they exercise it through legislative, executive and judicial bodies.
(2) A constitutional act may define when the people shall exercise state power directly.
Article 2 of the Constitution of the Czech Republic
The legislative function includes the adoption of constitutional as well as other laws. The material scope of the constitutional or legislative powers is not precisely defined. In terms of constitutional powers, it is merely stated that the Constitution may be amended only by constitutional acts. The substantive requisites of a democratic state governed by the rule of law may not be amended. Not even in the case of the acts does the Czech legal system include any complete enumeration of the issues which must or may be regulated by law. Nonetheless, the Constitution and the Charter of Fundamental Rights and Freedoms in various places define some areas that always require legal regulation. These so-called reservations of law are the basic instrument setting the minimum limits of legislative activities. The other areas of legal relations can be regulated by law if the legislator, i.e. Parliament, considers it to be necessary and adopts the relevant act complying with the constitutional provisions by means of constitutional and legal procedures.
Besides by acts, legal relations are also regulated by subordinate legislation, which is issued by the government, by individual ministries or by other central government authorities to implement a particular law and within its limits. The Constitution provides that, unlike the government, ministries and other administrative authorities may issue subordinate legislation if they are expressly empowered to do so by a particular law. The formulation of the empowerment in the law must be specific and also such that the authority may not change in the subordinate legislation the conditions given in the relevant act. The issue of subordinate legislation by the government and other authorities is, however, in the system of separation of state powers their own power, which is not derived from individual acts but arises directly from the Constitution.
