Commission composition: an audio-style guide

If I were explaining Commission composition to a new colleague in Brussels, I would not begin with a definition. I would begin with the scene. This card sits in Ch.2 Institutional Structure. Its wider background is this: institutions, legal acts and voting rules define who can do what. The essential point is simple: One Commissioner per Member State (currently 27), serving a five-year term.

The reason this matters is that EU history is rarely a list of isolated facts. It is a chain of choices, compromises and institutional consequences. Here, the useful nuance is: Headed by a President; Commissioners must act independently of national governments. That sentence turns the card from a memory test into a piece of political and legal understanding.

A good EU official listens for the structure beneath the story. Who is acting? Which institution has the power? Which treaty, procedure or policy instrument gives the action its force? With a fact, attach the detail to a consequence. A number, body or label is useful only when it changes how the Union works. That is also how EPSO distractors are built. They sound familiar, but one institutional detail is out of place.

Use Art. 17 TEU as your bookmark. Then say the card aloud in one flowing sentence: Commission composition matters because One Commissioner per Member State (currently 27), serving a five-year term. If that sentence sounds natural, you are no longer memorising a flashcard. You are learning to explain the Union as a living system.
