The EU treaties constitute the European Union’s ‘primary legislation’, which is comparable to constitutional law at national level. They thus lay down the fundamental features of the Union, in particular the responsibilities of the various actors in the decision-making process, the legislative procedures, under the Community system and the powers conferred on them. The treaties themselves are the subject of direct negotiations between the governments of the Member States, after which they have to be ratified in accordance with the procedures applying at national level (in principle by the national parliaments or by referendum).
The ‘secondary legislation’ is the third major source of Community law after the treaties (primary legislation) and international agreements. Secondary legislation comprises the binding legal instruments (regulations, directives and decisions) and non-binding instruments (resolutions, opinions) provided for in the EC Treaty, together with a whole series of other instruments such as the institutions’ internal regulations and Community action programmes.
Adopted by the Council in conjunction with the European Parliament or by the Commission alone, a regulation is a general measure that is binding in all its parts. A regulation is directly applicable, which means that it creates law which takes immediate effect in all the Member States in the same way as a national instrument, without any further action on the part of the national authorities.
Adopted by the Council in conjunction with the European Parliament or by the Commission alone, a directive is addressed to the Member States. Its main purpose is to align national legislation. A directive is binding on the Member States as to the result to be achieved but leaves them the choice of the form and method they adopt to realise the Community objectives within the framework of their internal legal order.
If a directive has not been transposed into national legislation in a Member State, if it has been transposed incompletely or if there is a delay in transposing it, citizens can directly invoke the directive in question before the national courts.
Adopted either by the Council, by the Council in conjunction with the European Parliament or by the Commission, a decision is the instrument by which the Community institutions give a ruling on a particular matter. By means of a decision, the institutions can require a Member State or a citizen of the Union to take or refrain from taking a particular action, or confer rights or impose obligations on a Member State or a citizen. A decision is an individual measure, and the persons to whom it is addressed must be specified individually and is binding in its entirety.
