The European Parliament is one of the major and most important organs of the European Union and Communities and its role and participation in those institutions’ decision-making process increases systematically, simultaneously with every successive reforming treaty entering into force. The present article is an attempt to present the European Parliament after the latest great events in the European Union, i.e. the election of June 2009 and 1 December 2009, when the Treaty of Lisbon came into force. The author attempts to answer numerous questions that are asked in connection with the last European election and the Treaty of Lisbon. He tries to show how this election and the Treaty of Lisbon changed the image of the European Parliament and strengthened its competence. He proposes many interesting theses, including one that the European election of 2009 together with the treaty of Lisbon are a turning point not only in the history of the European Parliament but also the history of the European integration and its effect: the European Union. In the article, there are many references to Poland and its experiences after the accession to the European Union in 2004 and in the European Parliament. The author proves that today the Poles are satisfied with the European Union membership and feel more confident in the European Parliament and in all the European Union salons.
