The European Commission

European Politics Fundamentals

Chapter 2 · The European Commission: The EU's Real Executive Body

Chapter 1 established that the EU's own real legal authority — direct effect, supremacy — makes it more than an international organization. This chapter covers the body that actually proposes and enforces that authority day to day: a genuinely unusual executive, structurally unlike any single national government this site's own Politics Subject has covered so far.

Structure: One Commissioner, Every Member State

The College of Commissioners

The Commission is formed by a College with one Commissioner per member state (27, following Brexit), serving five-year terms matching the European Parliament's own electoral cycle. Every Commissioner takes a real, formal oath of office: to be "completely independent" in carrying out their duties, and — critically — "neither to seek nor to take instructions from any Government." A Commissioner is legally required to represent the EU's own interest, not their home country's, once appointed.

Why this structural detail matters This is a genuine, deliberate design choice distinguishing the Commission from a body like the Council of the EU (covered in Chapter 4), where national ministers explicitly represent their own government's position. The Commission's own legitimacy rests on the fiction — enforced by a real oath — that its members stop being national representatives the moment they take office.

The Legislative Initiative Monopoly

Article 17(2) TEU

"Union legislative acts may only be adopted on the basis of a Commission proposal, except where the Treaties provide otherwise." In practice, this gives the Commission a near-total monopoly on formally proposing new EU legislation. The European Parliament and the Council of the EU — the two bodies that actually debate and adopt legislation — can only invite the Commission to draft a proposal; they cannot, in most policy areas, introduce a bill themselves the way an individual member of a national parliament routinely can.

A genuinely unusual feature by national-parliament standards In most democracies this site's own Politics Subject has already covered, an ordinary legislator can introduce a private member's bill. In the EU's own legislative process, that starting move belongs to one unelected body alone — a real, structural centralization of the agenda-setting power that has no clean national equivalent.

"Guardian of the Treaties": Real Enforcement Teeth

Article 17 TEU also names the Commission the treaties' own "guardian" — responsible for monitoring whether member states actually comply with EU law. Its main real tool is the infringement procedure under Article 258 TFEU, a formal three-stage process.

Stage 1: Formal Notice

The Commission writes to the member state, laying out the alleged breach and inviting a response.

Stage 2: Reasoned Opinion

If the response is unsatisfactory, the Commission issues a formal reasoned opinion and sets a deadline for compliance.

Stage 3: Referral to the CJEU

If the deadline passes without compliance, the Commission may refer the case to the Court of Justice of the EU — which, under Article 260 TFEU, can impose real financial penalties.

A real, dated penalty: Poland, 27 October 2021 The Court of Justice imposed a periodic penalty of €1 million per day on Poland for failing to suspend the operation of its own Supreme Court Disciplinary Chamber, which the Court had already found (15 July 2021) to violate judicial independence and impartiality requirements. This wasn't a symbolic gesture — it was a real, compounding financial cost applied directly against a member state's own government for continued non-compliance.

A real, significant recent ruling: Commission v Hungary (C-769/22) The Commission challenged a 2021 Hungarian law restricting minors' access to LGBTI-related content across media, education, and commerce, arguing it breached Article 2 TEU (the EU's own founding values) and Article 1 of the Charter of Fundamental Rights. The Court of Justice ruled unanimously that the law violated "the very identity of the Union" — the first ruling of its kind to invoke both provisions this way, and a real, concrete demonstration of how far the "guardian of the treaties" role can reach into a member state's own domestic legislation.

Choosing a Commission President: Formal Rule vs. Real Practice

The formal appointment procedure has two real steps: the European Council proposes a candidate by qualified majority, "taking into account" the European Parliament election results, and Parliament must then approve that candidate by a majority of its component members. An informal convention layered on top of this — the Spitzenkandidat ("lead candidate") process — holds that the winning European political party's own pre-announced lead candidate should become Commission President. This convention appears in no treaty at all.

The convention's real, documented breakdown: 2019 Manfred Weber led the European People's Party to the most seats in the May 2019 European Parliament election, making him the presumptive Spitzenkandidat pick. The European Council — led by French President Emmanuel Macron — refused to nominate either Weber or his main rival, and instead proposed Ursula von der Leyen, who had not been a lead candidate in the election at all. Parliament approved her, 383 votes to 327, in July 2019. The formal treaty procedure (Council proposes, Parliament approves) held; the informal democratic convention did not.

Applying Chapter 1's Own Framework

	A Typical National Executive	The European Commission
Who chooses the leader	Directly elected, or chosen by a national legislature	Proposed by member-state governments (Council), approved by a directly elected body (Parliament) — a genuine hybrid
Who can propose new law	Any legislator can typically introduce a bill	The Commission holds a near-total monopoly, per Article 17(2) TEU
Loyalty of individual members	Ministers typically remain party/government figures	Commissioners take a real oath of independence from their own national government

Hands-On Exercises

Exercise 1 — Tracing an Infringement Procedure

A member state ignores the Commission's own formal notice and reasoned opinion regarding a law that breaches EU environmental legislation. List, in order, the remaining real steps available to the Commission, and name the real financial consequence a member state risks at the final stage.

→ Solution

Exercise 2 — Convention vs. Treaty

Using the real 2019 Weber/von der Leyen case, explain the real, structural difference between a political convention (like Spitzenkandidat) and a binding treaty rule (like the Council-proposes/ Parliament-approves procedure). Which one actually determined the outcome, and why?

→ Solution

Exercise 3 — The Independence Oath in Practice

A Commissioner's own home country asks them to block a Commission proposal that would harm one of that country's key industries. Using the real, verified oath of office, explain whether the Commissioner is legally permitted to comply with that request.

→ Solution

Quick Reference — Chapter 2

The College of Commissioners has one member per member state (27), each bound by a real oath to act independently of their own national government
Article 17(2) TEU gives the Commission a near-total monopoly on proposing new EU legislation — Parliament and the Council can only invite a proposal, not introduce one directly in most cases
Article 258 TFEU's real three-stage infringement procedure (formal notice → reasoned opinion → CJEU referral) can end in real financial penalties under Article 260 TFEU — Poland was fined €1 million/day starting 27 October 2021
Commission v Hungary (C-769/22) shows the "guardian of the treaties" role reaching directly into a member state's own domestic legislation, ruled a violation of "the very identity of the Union"
The Spitzenkandidat convention is real but non-binding — its 2019 breakdown (Weber passed over for von der Leyen) shows the formal treaty procedure, not the informal democratic convention, actually determines the outcome
