Multilevel Governance and Principle of Subsidiarity in the European Union

Due to European Union enlargement and its power development over time, member states learned to restrict their own sovereignty in the favour of the Union. Therefore, I believe it is necessary to discuss about multi-level governance within Union; governance that can be achieved by correct application of the principle of subsidiarity, as is mentioned in Lisbon Treaty, together with principle of proportionality. Moreover, my purpose is to present also the principle of subsidiarity impact within a EU member state, Spain, where is realized multi-level governance.
