Statutes
A statute is a basic act of the universally binding law in Poland. The statutes are adopted by the Sejm. The right of legislative initiative belongs to a group of at least 100,000 citizens, and also by at least 15 Members of the Senate, the President or the Council of Ministers.
Treaties
Ratified international agreements possess the force of the statute. Once an agreement is published, it becomes a part of the domestic legal system and may be applied directly. Ratification is within the competence of the President of the Republic of Poland.
Some agreements require prior consent before ratification and expressed in the statute. In case where such an agreement contradicts with the statute, the agreement prevails.
Regulations
Regulations are issued only by those organs that are expressly stated in the Constitution. Moreover, regulations have to be issued on the basis of specific authorization contained in the statute and in the purpose to implement the statute.
The competent organs to issue the regulations are the President of Republic of Poland, the Council of Ministers, the National Broadcasting Council, the Chairman of the Committee who is a member of the Council of Ministers, and the minister that manages the relevant area of public administration.
Local law
The acts of local law are binding within territory where the issuing organ exercises its powers. These acts may only be issued on the basis provided in the statute and within the limits prescribed in the statute.
