the European Community (EC). The TEU also established the superior entity, the European Union
(EU), but it did not replace the European Communities. Rather, it supplemented them by two new
processes: the Common Foreign and Security Policy (CFSP) and the Police and Judicial Co-
operation in Criminal Matters (PJCCM). It has generally been the EC that has been party to treaties
with third states.

The structure created by the TEU has been likened to a (rather badly designed) Ancient Greek
temple having only three pillars surmounted by a pediment. The middle pillar (and certainly the
fattest) represents the European Community (EC), flanked by rather thin second and third pillars
representing the CFSP and the PJCCM respectively.

The pediment contains the common
institutions, political values, objectives, and amendment and accession procedures. However, this
deceptively simple image hides the fact that the common institutions operate with different powers,
procedures and legal consequences, depending on the substance of the matter, so the image of a
Gothic cathedral might be closer to the complex reality.
But the heart of the EU remains the first pillar, the European Community, without which the
edifice would collapse. Unlike the CFSP and the PJCCM, the work of the EC covers several large
subject areas, and the resulting acts by the Council of Ministers are subject to the sophisticated legal
order created by the EC Treaty and the judgments of the European Court of Justice, in particular the
primacy of EC law and its direct effect.
But should the new Constitution for Europe ever enter into force, the correct term will then be the
European Union, or simply, the Union. Therefore, in a spirit of optimism, the rest of this book refers
primarily to the EU, even though, as a matter of law and in contrast to the EC, the EU is not yet
generally accepted as having international legal personality.

The EC is referred to when dealing
with a treaty to which the EC is a party or to legislation which only the EC can make.

The fundamental aim of the EU is to bring its member states closer together economically,
socially and politically. The EU has become an extraordinarily complex regional organisation, in
terms of the treaties governing it, its procedures and its legislation. But, although it has a certain
degree of supranational power, it is not a federation. This chapter will outline the structure of the EU
and how it works. It will not attempt to describe the substantive law developed by the EU over
nearly fifty years in the areas of, for example, a customs union, the single market,
