The lingering European financial crisis continues to threaten the Eurozone and, in the opinion of German Chancellor Angela Merkel, the very survival of the European idea. With this apocalyptic rhetoric, it is easily forgotten that only nine years earlier Europe overcame a predicament that was, at the time, equally described as the most challenging in its history. Two failed referendums in Member States of the European Union (Member States)—namely, in France and the Netherlands—stopped the Treaty establishing a Constitution for Europe (Constitutional Treaty) in its tracks and led to an extended “period of reflection” for Europe's leaders. From this emerged a reboot of the Constitutional Treaty, now dubbed the Treaty of Lisbon, with few substantial changes, but more success throughout the ratification procedures. The final hurdle presented itself in the form of institutionally strong Constitutional Courts (CC) and Tribunals (CT) of the European Member States. Of these, the following were at one time or another seized with complaints against the ratification of the Lisbon Treaty: The Austrian Verfassungsgerichtshof (Austrian CC), the Belgian CC, the Ústavní soud České republiky (Czech CC), the French Conseil Constitutionnel (French CC), the German Bundesverfassungsgericht (German CC), the Hungarian CC, the Latvijas Republikas Satversmes tiesa (Latvian CC), the Polish Trybunał Konstytucyjny (Polish CT), and the Tribunal Constitucional de España (Spanish CT).
