The legal system forged under the Treaty of Rome along with the European Court of Justice was undeniably weak in the beginning. Declarations of Treaty non compliance were unable to embarrass member states into abidance and were easily ignored or brushed aside, as politicians would make use of the political medium to motivate and escape the scope of the Treaty s legal mechanisms. However, a drastic chance has taken place. Currently, even the thought of being brought before the European Court of Justice can prove sufficient to convince a national government to back down on controversial issues regarding national interests and objectives. This change has transformed the European Court of Justice and the European Union along with it. Therefore, it is the objective of the author to critically consider how the transformation of the European Court of Justice arose.
