Wpływ traktatu z Lizbony na rozwój wspólnej polityki bezpieczeństwa i obrony Unii Europejskiej

The author of the article conducts a comparative analysis of the Lisbon Treaty with the Constitutional Treaty concerning the provisions of common security and defence policy. The analysis proves that provisions that had caused disputes among most European Union’s Member States were abandoned in the Lisbon Treaty. Differentiating and defining the common security and defence policy in one “section” and collecting there all articles concerning the functioning of common security and defence policy positively influenced the clarity and concreteness. In the Treaty of Nice the provisions relating to common security and defence policy were a part of common foreign policy and security, thereby they were less precise.
