SYSTEM REFORM OF THE EUROPEAN UNION IN THE TREATY OF LISBON (Reforma ustrojowa Unii Europejskiej w traktacie lizbonskim)

The article deals with the reform of the European Union system in the Lisbon Treaty of 13 December 2007. Analysis is limited to the so-called horizontal changes, also known as structural changes, i.e. those which are significant for the whole EU. Changes in the institutional system, internal market, space of liberty, security and justice, as well as changes in the common foreign policy and security policy of the EU have been left out of considerations. The author therefore focuses on the following issues: transformation of the European Union into a uniform international organization; expansion of the EU's axiology; establishing of division of competence between the EU and its member states; systematization and simplification of the catalogue of legal acts and legal procedures; modification of the democratic procedures of the EU; strengthening of the position of national parliaments in the legislative process; procedures of revisions of treaties and changes in the functioning of closer cooperation.
