The Council comprises ministers of the Member States. Its membership changes according to the matter under discussion, for instance it comprises national ministers of agriculture if agriculture is the topic under discussion.

EU measures, generally comprising secondary legislation, can only be adopted by the EU institutions if the Treaty confers on them the power to legislate in the relevant area. The 'legal base' of an EU measure is the Treaty article conferring that power. The Treaty article forming the legal base also sets out the procedure and the voting requirements in the Council - unanimity, simple majority, or qualified majority - for the adoption of the legislation.

Qualified majority voting operates as a system of weighted voting. The larger the Member State, the more votes it holds. For instance the larger Member States, such as France and Germany, hold 29 votes each and the smallest, Malta, holds only 3 votes.

Tariffs are taxes that governments levy on imports of goods in order to protect domestic producers and raise revenues for the government. Sometimes tariffs are accompanied by quotas, which set import limits. Sometimes governments are able to restrict trade and protect domestic producers without the use of tariffs. National product safety standards are an example of a non-tariff barrier to trade. For example, by setting national safety standards, a country can effectively bar foreign producers from selling their goods in the country unless they make modifications for that specific national market-usually too costly for a manufacturer to undertake. Non-tariff barriers to trade proliferated during the economic downturn in the 1970s, as national governments sought to protect their domestic producers. 

European Political Co-operation (EPC), the Common Foreign and Security Policy (CFSP) and European Security and Defence Policy (ESDP) are all forms of political co-operation in the EU. This means that they are all programmes that share the goal of co-operation in the 'high politics' of foreign policy, either in the diplomatic or the military realm. These forms of co-operation are intergovernmental, which means that the European Council, and not the Commission, plays a leading role. Most decisions in political co-operation are taken by unanimity, although there are provisions for qualified majority voting in limited circumstances as well as provisions for member states to abstain from voting without blocking the process of political cooperation among other member states.

The European Union was set up as a three-pillar structure, comprising the three Communities (the first pillar), a Common Foreign and Security Policy (the second pillar) and Co-operation on Justice and Home Affairs (the third pillar).

The fourth enlargement was that of 1995, which admitted Austria, Finland and Sweden. The fifth enlargement in 2004 was the single biggest expansion of the EU. It brought ten new member states into the EU - eight from Central and Eastern Europe - and two small Mediterranean states - Cyprus and Malta.

The European Single Market is a single market which seeks to guarantee the free movement of goods, capital, services, and labour. 

A single market is a market in which most trade barriers have been removed (for goods) with some common policies on product regulation, and freedom of movement of the factors of production (capital and labour) and of enterprise and services including the abolition of passport controls. 

The goal is that the movement of capital, labour, goods, and services between the members is as easy as within them. Control of human trafficking is not a feature of the single market.

The constitutional structure of European Union, as established by the Treaty on European Union 1992, is often described as a Europe of 'variable geometry'. It incorporated both supranational elements (decision-making by the Community institutions, acting partly or entirely independently of the Member States, within the first pillar).

European Political Co-operation (EPC) created an intergovernmental framework for coordination on foreign policy issues. This represented 'deepening' of integration and it allowed Member States to develop common positions on the Middle East (which was important as part of Europe's response to the oil crisis caused by OPEC embargoes), and at the Conference for Security and Co-operation in Europe and for UN General Assembly voting. This co-operation was limited. EPC did not take place within the institutional framework of the European Community; co-operation took place purely on an intergovernmental basis, without the involvement of the European Commission, the European Parliament and the European Court of Justice. It was also limited-it did not create a foreign minister position.

A directive is a form of European Union secondary legislation. Article 288 TFEU describes a directive as 'binding as to the result to be achieved, upon each Member State to which it is addressed, but leaving to the national authorities the choice of form and methods'.
