It is common to hear that “Brussels has passed a new law”, particularly when a new European regulation attracts public attention. The expression is understandable, but it hides a more complicated reality: EU legislation is rarely the work of a single institution, and the process behind a final legal text can reveal as much about the Union as the law itself.
The European Union does not operate like a state with one government and one parliament. Its legislative system distributes power between institutions representing different interests, with the aim of ensuring that decisions reflect both the broader European perspective and the positions of the Member States. Understanding how these institutions interact is therefore essential to understanding not only how EU law is made, but also why negotiations can be lengthy and their outcomes difficult to predict.
From a Commission proposal to European legislation
Under the ordinary legislative procedure, which applies to many of the EU's main policy areas, the process normally begins with the European Commission. It has the right of legislative initiative in most of these areas and is responsible for preparing proposals, which may take the form of regulations, directives or decisions depending on their purpose and legal basis. However, presenting a proposal does not mean that the Commission can determine its final content or adopt it on its own.
That responsibility normally belongs jointly to the European Parliament and the Council of the European Union, the two co-legislators under the ordinary legislative procedure. Although both participate in adopting the same legislation, they represent different interests within the European political system. Parliament is directly elected by EU citizens, whereas the Council brings together ministers from national governments, with the relevant ministers attending according to the policy under discussion.
This distinction is central to the EU's institutional balance. Parliament provides a direct channel for democratic representation at European level, while the Council ensures that national governments participate in decisions affecting their countries. Neither institution simply approves the other's position: both can propose amendments, and legislation can normally be adopted only when they agree on the same text.
As a result, a proposal may change considerably between its initial presentation and final adoption. A measure that begins as an attempt to address a common European problem must pass through institutions with different political priorities, national concerns and views about how much action should take place at EU level. The final text is therefore often a compromise between ambitions that were not necessarily compatible at the outset.
The negotiations behind the final text
Much of this work takes place before the public sees a final vote. Parliamentary committees examine proposals, prepare reports and consider amendments, while national officials and experts work on the Council's position. These discussions can involve detailed questions about definitions, implementation deadlines, enforcement powers and exemptions, all of which may determine how legislation operates in practice.
Trilogues are particularly important in this process. These informal negotiations bring together representatives of Parliament, the Council and the Commission to help the two co-legislators reach an agreement. They do not replace the formal legislative procedure, but they can help reconcile different positions before the institutions complete their respective stages of approval. Once a compromise has been reached, it still has to be formally endorsed through the applicable procedures.
This is one reason why reading a newly adopted regulation does not always explain how the EU reached its decision. The published text establishes the rules that will apply, but the negotiations behind it reveal which concerns prevailed, which concessions were necessary and how the institutions balanced competing objectives. For anyone working with European legislation, understanding that institutional background can be just as important as knowing the final wording.
If Parliament and the Council cannot agree, the ordinary legislative procedure provides further stages for resolving their differences, including conciliation in certain circumstances. Representatives of both institutions then attempt to agree on a joint text. If the process fails to produce an agreement, the proposal is not adopted. The system is designed to require cooperation between the co-legislators rather than allow either of them to impose its preferred version unilaterally.
Three institutions with very different roles
Confusion also arises from the names of the EU's institutions, particularly the European Council and the Council of the European Union. The European Council brings together the heads of state or government of the Member States and sets the Union's general political direction and priorities. Although its conclusions can shape the agenda for future legislation, it does not normally exercise the legislative function.
The Council of the European Union, by contrast, brings together national ministers and acts as a co-legislator alongside Parliament. The Commission occupies a different position: it normally proposes legislation, supports the legislative process and monitors the application of EU law. These responsibilities are not interchangeable, even though the institutions work closely together.
There is also a distinction between adopting EU legislation and applying it. Depending on the legal instrument and the policy area, national authorities may need to implement EU rules, enforce them or adapt domestic legislation. The Commission monitors compliance, while the Court of Justice of the European Union plays a central role in interpreting EU law and ensuring that it is respected. The precise arrangements depend on the applicable legislation and the Treaties.
The ordinary legislative procedure is not the only route to adoption, either. The Treaties establish special legislative procedures for certain areas, in which Parliament and the Council do not necessarily have the same roles or powers. Any explanation of EU law-making must therefore begin with the relevant legal basis rather than assume that every measure follows an identical path.
Why the institutional balance matters
The complexity of the European legislative process is sometimes presented as evidence that the EU is distant from its citizens or unable to act efficiently. Lengthy negotiations and compromises can indeed make responsibility harder to identify, particularly when political actors describe an unpopular decision simply as something imposed by “Brussels”. Yet the institutional structure also reflects the particular challenge the Union faces: making common rules for 27 Member States while maintaining democratic representation and a role for national governments.
In my view, this is the most important point to understand about EU legislation. The question is not simply which institution adopted a particular measure, but how the different institutions influenced its content and where responsibility lies for the choices ultimately made. Public debate becomes less informative when the entire process is reduced to a single actor, because that obscures the role of elected representatives, national ministers and the compromises required to reach an agreement.
The system is not free from shortcomings. Informal negotiations can make the process difficult for citizens to follow, and the technical nature of legislation can create distance between political decisions and their practical consequences. Greater transparency and clearer communication about the responsibilities of each institution would help the public understand not only what the EU has decided, but also why it has decided it.
Ultimately, EU law is neither simply imposed by the Commission nor produced by national governments acting independently. Under the ordinary legislative procedure, it emerges from a process in which the Commission proposes, Parliament and the Council negotiate and adopt, and national authorities apply the resulting rules where required. Understanding these distinctions makes it easier to assess European decisions critically and to identify who had the power to shape them.
To understand European legislation, it is not enough to read the final law. We also need to understand the institutions, negotiations and competing interests that made it possible.
